Tracing "Ethical Subjectivities" in Science Education: How Biology Textbooks Can Frame Ethico-Political Choices for Students

Science.gov (United States)

Bazzul, Jesse

2015-02-01

This article describes how biology textbooks can work to discursively constitute a particular kind of "ethical subjectivity." Not only do textbooks constrain the possibilities for thought and action regarding ethical issues, they also require a certain kind of "subject" to partake in ethical exercises and questions. This study looks at how ethical questions/exercises found in four Ontario textbooks require students and teachers to think and act along specific lines. These include making ethical decisions within a legal-juridical frame; deciding what kinds of research should be publically funded; optimizing personal and population health; and regulation through policy and legislation. While engaging ethical issues in these ways is useful, educators should also question the kinds of (ethical) subjectivities that are partially constituted by discourses of science education. If science education is going to address twenty-first century problems such as climate change and social inequality, educators need to address how the possibilities for ethical engagement afforded to students work to constitute specific kinds of "ethical actors."

Correlation between MCAT biology content specifications and topic scope and sequence of general education college biology textbooks.

Most American colleges and universities offer gateway biology courses to meet the needs of three undergraduate audiences: biology and related science majors, many of whom will become biomedical researchers; premedical students meeting medical school requirements and preparing for the Medical College Admissions Test (MCAT); and students completing general education (GE) graduation requirements. Biology textbooks for these three audiences present a topic scope and sequence that correlates with the topic scope and importance ratings of the biology content specifications for the MCAT regardless of the intended audience. Texts for "nonmajors," GE courses appear derived directly from their publisher's majors text. Topic scope and sequence of GE texts reflect those of "their" majors text and, indirectly, the MCAT. MCAT term density of GE texts equals or exceeds that of their corresponding majors text. Most American universities require a GE curriculum to promote a core level of academic understanding among their graduates. This includes civic scientific literacy, recognized as an essential competence for the development of public policies in an increasingly scientific and technological world. Deriving GE biology and related science texts from majors texts designed to meet very different learning objectives may defeat the scientific literacy goals of most schools' GE curricula.

Gaia Theory in Brazilian High School Biology Textbooks

Science.gov (United States)

Do Carmo, Ricardo Santos; Nunes-Neto, Nei Freitas; El-Hani, Charbel Niño

2009-04-01

Gaia theory proposes that a cybernetic system including the biota and the physicochemical environment regulates environmental variables at a global scale, keeping them within a range that makes Earth inhabitable by living beings. One can argue that this theory can play an important role in school science, since it bears upon current environmental problems, contributes to cross-disciplinary learning, and may help students understand the nature of science. Nevertheless, discourses about Gaia include both scientific and non-scientific ideas, and, consequently, this theory has been seen as pseudoscience, or even antiscience, as an unwarranted view, entangled with mysticism. But an informed view about the contributions and risks associated with Gaia as part of science education depends on a general analysis about the treatment of this theory in school knowledge. Here, we offer the first analysis of this sort, critically evaluating how Gaia is addressed in a representative sample of Brazilian textbooks ( n = 18). We present data about the presence or not of Gaia theory among the contents covered by the textbooks, the presence of the claim that Earth is living, whether and how they use analogies to justify this claim, the discussion of evidence for and against Gaia, and the treatment of its relevance to current issues. Gaia theory is explicitly addressed in ca. 39% of the analyzed textbooks. There is a general script that the textbooks that explicitly name the theory follow when discussing Gaia. First, they argue that life affects the environment, and support this argument by means of examples, then, explain what the Gaia theory proposes, discuss evidence in favor either of the idea that Earth is living or Gaia theory in general, introduce one or more analogies to justify the claim of a living Earth, and, finally, offer remarks on the current importance of Gaia. Three analogies used by Lovelock himself were found in the analyzed textbooks, Gaia as a superorganism, the

Corrêa, Anderson Domingues; Caminha, Juliana dos Reis; de Souza, Cristina Alves Magalhães; Alves, Luiz Anastacio

2013-10-01

The inappropriate use of medication represents a major threat to public health and drugs rank first among the agents causing intoxication in Brazil, ahead of poisons for rodents and insects, illegal drugs, pesticides, cleaning products and spoiled food. The National Curriculum of Secondary Education Parameters (PCN+) give major emphasis to health, since the reference to Drugs is mentioned repeatedly in the text. The scope of this research was to study the approaches to drug use in textbooks. For this purpose, eleven biology textbooks were analyzed, namely six single volumes and five with three volumes each, i.e. a total of twenty-one volumes. The rational use of medication should be considered an important topic for the promotion of health which affects all sectors of society and should be emphasized in basic education. In line with this idea and based on the results obtained, it is suggested that the textbooks analyzed should be adapted to the new legislation and content that addresses Rational Drug Use, thus meeting the recommendations of PCN+. In this context, the books should concisely address the following topics: self-medication, adherence to drug treatment, advertisements and reports on drugs, among others.

Straight, white teeth as a social prerogative.

Science.gov (United States)

Khalid, Abeer; Quiñonez, Carlos

2015-06-01

A distinguishing feature of North American society is preoccupation with self-image, as seen in the ritualistic nature of bodily practices aimed at constantly improving the body. Nowhere is this more apparent than in the prevailing fixation with straight, white teeth. While there is an ever-expanding literature on the sociology of body, very little has been written on teeth in this context. Using literature from anthropology, biology, dentistry, sociology and social psychology, this study attempts to answer: (1) Why have straight, white teeth become a beauty ideal in North American society? (2) What is the basis for this ideal? (3) How is this ideal propagated? It demonstrates that dental aesthetic tendencies are biologically, culturally and socially patterned. Concepts from the works of Pierre Bourdieu and Michel Foucault are used to illustrate how straight, white teeth contribute towards reinforcing class differences and how society exercises a disciplinary power on individuals through this ideal. It is concluded that modified teeth are linked to self and identity that are rooted in social structure. Moreover, teeth demonstrate the ways in which class differences are embodied and projected as symbols of social advantage or disadvantage. Implications on professional, public health, sociological and political levels are considered. © 2015 Foundation for the Sociology of Health & Illness.

Misrepresentations of evolutionary psychology in sex and gender textbooks.

Winegard, Benjamin M; Winegard, Bo M; Deaner, Robert O

2014-05-20

Evolutionary psychology has provoked controversy, especially when applied to human sex differences. We hypothesize that this is partly due to misunderstandings of evolutionary psychology that are perpetuated by undergraduate sex and gender textbooks. As an initial test of this hypothesis, we develop a catalog of eight types of errors and document their occurrence in 15 widely used sex and gender textbooks. Consistent with our hypothesis, of the 12 textbooks that discussed evolutionary psychology, all contained at least one error, and the median number of errors was five. The most common types of errors were "Straw Man," "Biological Determinism," and "Species Selection." We conclude by suggesting improvements to undergraduate sex and gender textbooks.

Comparative analysis of knowledge representation and reasoning requirements across a range of life sciences textbooks.

Chaudhri, Vinay K; Elenius, Daniel; Goldenkranz, Andrew; Gong, Allison; Martone, Maryann E; Webb, William; Yorke-Smith, Neil

Using knowledge representation for biomedical projects is now commonplace. In previous work, we represented the knowledge found in a college-level biology textbook in a fashion useful for answering questions. We showed that embedding the knowledge representation and question-answering abilities in an electronic textbook helped to engage student interest and improve learning. A natural question that arises from this success, and this paper's primary focus, is whether a similar approach is applicable across a range of life science textbooks. To answer that question, we considered four different textbooks, ranging from a below-introductory college biology text to an advanced, graduate-level neuroscience textbook. For these textbooks, we investigated the following questions: (1) To what extent is knowledge shared between the different textbooks? (2) To what extent can the same upper ontology be used to represent the knowledge found in different textbooks? (3) To what extent can the questions of interest for a range of textbooks be answered by using the same reasoning mechanisms? Our existing modeling and reasoning methods apply especially well both to a textbook that is comparable in level to the text studied in our previous work (i.e., an introductory-level text) and to a textbook at a lower level, suggesting potential for a high degree of portability. Even for the overlapping knowledge found across the textbooks, the level of detail covered in each textbook was different, which requires that the representations must be customized for each textbook. We also found that for advanced textbooks, representing models and scientific reasoning processes was particularly important. With some additional work, our representation methodology would be applicable to a range of textbooks. The requirements for knowledge representation are common across textbooks, suggesting that a shared semantic infrastructure for the life sciences is feasible. Because our representation overlaps

Considerations of multicultural science and curriculum reform: A content analysis of state-adopted biology textbooks in Florida

Science.gov (United States)

Delgato, Margaret H.

The purpose of this investigation was to determine the extent to which multicultural science education, including indigenous knowledge representations, had been infused within the content of high school biology textbooks. The study evaluated the textbook as an instructional tool and framework for multicultural science education instruction by comparing the mainstream content to indigenous knowledge perspectives portrayed in the student and teacher editions of 34 textbooks adopted in Florida within the last four adoption cycles occurring from 1990 to 2006. The investigation involved a content analysis framed from a mixed methods approach. Emphasis was placed, in consideration of the research questions and practicality of interpreting text with the potential for multiple meanings, within qualitative methods. The investigation incorporated five strategies to assess the extent of multicultural content: (1) calculation of frequency of indigenous representations through the use of a tally; (2) assessment of content in the teacher editions by coding the degree of incorporation of multicultural content; (3) development of an archaeology of statements to determine the ways in which indigenous representations were incorporated into the content; (4) use of the Evaluation Coefficient Analysis (ECO) to determine extent of multicultural terminologies within content; and (5) analysis of visuals and illustrations to gauge percentages of depictions of minority groups. Results indicated no solid trend in an increase of inclusion of multicultural content over the last four adoption cycles. Efforts at most reduced the inclusion of indigenous representations and other multicultural content to the level of the teacher edition distributed among the teacher-interleafed pages or as annotations in the margins. Degree of support of multicultural content to the specific goals and objectives remained limited across all four of the adoption cycles represented in the study. Emphasis on

2009-01-01

Full Text Available English language teaching materials (textbooks play an important role in many language classrooms, but recently there have been a lot of debates within the English language teaching profession based on the actual role that materials play in teaching English as a foreign language. Arguments have encompassed both the potential and the limitations of materials used for 'guiding' students through the learning processes and curriculum as well as the needs and preferences of teachers who are using the textbooks that are available. Other issues that have arisen in recent years include textbook design and practicality, methodological validity, the role of textbooks in innovation, the authenticity of materials in terms of their representation of language, communicative textbooks, and balance in presenting the language skills as well as cultural components.The purpose of this article is to report the findings of a study carried out in 2006 into how Iranian textbooks could be made more communicative. The textbooks referred to are three English language textbooks, which are currently used in Iranian Secondary Schools. Although the work has been done within Iranian context, many suggestions could be applied to other foreign/second language situations.I will start my discussion by presenting an overview about the English language teaching in Iran, before and after the revolution. This will be followed by presenting the findings of this research that would include the Iranian ELT curriculum, the questionnaire survey (author's and teachers' perspectives as well as their discomfort will be addressed as well as introducing the English language coursebooks for secondary schools in Iran (topic, progression, structure of the lessons, types of exercises etc.. I will then present a discussion on findings of this research which would be a detailed exemplary criticism and suggestions for changes to make the materials communicative.The findings of this explanatory case

Full Text Available eTextbooks have steadily and recently more rapidly penetrated the textbook market. In order to effectively support students’ learning, it is important to comprehend students’ experiences using eTextbooks. This survey study was designed to gain an understanding of students’ experiences in using eTextbooks and variables that impact their experiences, perceptions, and attitudes towards eTextbooks. In a total of 33 courses, faculty members at five state university campuses in California participated in the eTextbook pilot project during the fall of 2010. Six hundred and sixty-two student questionnaires were returned from those courses. Key findings include: 1 More than one-third of the students were satisfied with the eTextbook; 2 more than half of the students felt that the eTextbook was easy-to-use; 3 older students (22 or older tended to have more positive experiences with the eTextbook than younger students; and 4 students most liked the eTextbook’s cost, accessibility, light weight, and keyword search features. This study implies that the eTextbook must be a high-quality, easy-to-use resource to serve as a viable textbook option for student learning.

Neglected issues concerning teaching human adrenal steroidogenesis in popular biochemistry textbooks.

Han, Zhiyong; Elliott, Mark S

2017-11-01

In the human body, the adrenal steroids collectively regulate a plethora of fundamental functions, including electrolyte and water balance, blood pressure, stress response, intermediary metabolism, inflammation, and immunity. Therefore, adrenal steroidogenesis is an important biochemistry topic for students to learn in order for them to understand health consequences caused by deficiencies of enzymes in the adrenal steroidogenic pathways. However, popular biochemistry textbooks contain insufficient information and may sometimes give students a misimpression about certain aspects of human adrenal steroidogenesis. This article highlights two neglected issues in teaching human adrenal steroidogenesis in popular biochemistry textbooks. The purpose of this article is to draw attention to these issues. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(6):469-474, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

Fixed field alternating gradient (FFAG) accelerators are recently subject to a strong revival. They are usually designed in a circular shape; however, it would be an asset to guide particles with no overall bend in this type of accelerator. An analytical development of a straight FFAG cell which keeps zero-chromaticity is presented here. A magnetic field law is thus obtained, called “straight scaling law”, and an experiment has been conducted to confirm this zero-chromatic law. A straight scaling FFAG prototype has been designed and manufactured, and horizontal phase advances of two different energies are measured. Results are analyzed to clarify the straight scaling law.

Straight until proven gay: A systematic bias toward straight categorizations in sexual orientation judgments.

Science.gov (United States)

Lick, David J; Johnson, Kerri L

2016-06-01

Perceivers achieve above chance accuracy judging others' sexual orientations, but they also exhibit a notable response bias by categorizing most targets as straight rather than gay. Although a straight categorization bias is evident in many published reports, it has never been the focus of systematic inquiry. The current studies therefore document this bias and test the mechanisms that produce it. Studies 1-3 revealed the straight categorization bias cannot be explained entirely by perceivers' attempts to match categorizations to the number of gay targets in a stimulus set. Although perceivers were somewhat sensitive to base rate information, their tendency to categorize targets as straight persisted when they believed each target had a 50% chance of being gay (Study 1), received explicit information about the base rate of gay targets in a stimulus set (Study 2), and encountered stimulus sets with varying base rates of gay targets (Study 3). The remaining studies tested an alternate mechanism for the bias based upon perceivers' use of gender heuristics when judging sexual orientation. Specifically, Study 4 revealed the range of gendered cues compelling gay judgments is smaller than the range of gendered cues compelling straight judgments despite participants' acknowledgment of equal base rates for gay and straight targets. Study 5 highlighted perceptual experience as a cause of this imbalance: Exposing perceivers to hyper-gendered faces (e.g., masculine men) expanded the range of gendered cues compelling gay categorizations. Study 6 linked this observation to our initial studies by demonstrating that visual exposure to hyper-gendered faces reduced the magnitude of the straight categorization bias. Collectively, these studies provide systematic evidence of a response bias in sexual orientation categorization and offer new insights into the mechanisms that produce it.

Straight lines of neutron scattering in biology: a review of basic controls in SANS and EINS.

Science.gov (United States)

Zaccai, Giuseppe

2012-10-01

Neutron and X-ray beams in scattering experiments have similar wavelengths and explore the same length scale (~1 Å or 0.1 nm). Data collection and analysis are also broadly similar for both radiation types. There are fundamental differences, however, between the interaction of X-rays and neutrons with matter, which makes them strongly complementary for structural studies in biology. The property of neutrons to distinguish natural abundance hydrogen from its deuterium isotope and the dispersion relation that leads to the energy of ~1 Å neutrons being of the order of thermal energy are well known. They form the basis, respectively, of contrast variation on the one hand and energy-resolved scattering experiments to study macromolecular dynamics-neutron-specific scattering methods on the other. Interestingly, analysis procedures for the structural and dynamics experiments display common aspects that can be expressed as straight-line relationships. These not only act as controls of good sample preparation, but also yield model-free parameters on an absolute scale that provide fundamental information on the structure and dynamics of the system under study.

Simon, Josep; García-Belmar, Antonio

Education and textbooks have traditionally been standard objects of research in the history of science, technology, and medicine. However, they have often remained marginal in the formulation of large historiographical questions. In the last decades, the work of some historians of science has challenged this state of affairs. STEP has promoted a distinctive focus on education and textbooks, compared to other scholarship cultures such as the Anglo-American. This essay reviews its work in this field and stresses the potential of education and textbooks to produce interdisciplinary research in local, national, and international perspective.

Weighted straight skeletons in the plane.

Biedl, Therese; Held, Martin; Huber, Stefan; Kaaser, Dominik; Palfrader, Peter

2015-02-01

We investigate weighted straight skeletons from a geometric, graph-theoretical, and combinatorial point of view. We start with a thorough definition and shed light on some ambiguity issues in the procedural definition. We investigate the geometry, combinatorics, and topology of faces and the roof model, and we discuss in which cases a weighted straight skeleton is connected. Finally, we show that the weighted straight skeleton of even a simple polygon may be non-planar and may contain cycles, and we discuss under which restrictions on the weights and/or the input polygon the weighted straight skeleton still behaves similar to its unweighted counterpart. In particular, we obtain a non-procedural description and a linear-time construction algorithm for the straight skeleton of strictly convex polygons with arbitrary weights.

2016-01-01

Perioperative straight sinus thrombosis is extremely rare. A 59-year-old female was admitted to our department because of incidentally found small anterior cerebral artery (A1) aneurysm with microbleeding. After clipping the cerebral aneurysm, she had delayed emergence from anesthesia, total aphasia, and right hemiparesis. Fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) of the head showed hyperintensity in the bilateral caudate nuclei, putamina, and thalami, and computed tomography of the head showed a hyperdense straight sinus, suggesting straight sinus thrombosis. Her neurologic symptoms improved gradually, and she achieved a full clinical recovery, with radiological evidence of recanalization of the straight sinus at follow-up. The possibility of straight sinus thrombosis should be considered in postoperative patients with unexplained postoperative deficits when MRI demonstrates hyperintensity in the bilateral basal ganglia and thalami on FLAIR signal images.

[Hygienic Assesment of Educational Texts: Methodical Approaches and Evaluation of Difficulties for Children of Secondary Textbooks].

Kuchma, V R; Tkachuk, E A

2015-01-01

The understandability and readability of the text are significant indicators of evaluation of textbooks. The aim of the study - rationale of improving the readability and understandability of textbooks. 60 modern textbooks for 5-11th classes on History, Physics, Biology and 23 textbooks of 1960-1980's edition. Flesch index was used to assess the readability, Fogh index - to evaluate understandability. The readability and understandability of texts in textbooks of 1960-1980's and modern editions have no differences and show the same complexity of old and modern textbooks for students. The indicator of understandability of textbooks for primary classes corresponds to age norm and is 4.4±0.2 points. The indicator of readability for these books is less age norm and is 53.8±2.9 points, which increases the physiological cost of educational activities of children of primary school age. Children's readability and understandability of school textbooks are a significant factor of intensity of training activities and can be objectively assessed by Flesch and Fogh indices, that it is appropriate for an objective hygienic assessment of the tension of the educational activities for children. The main direction of optimization of the tension of educational activity is to reduce the intellectual and emotional loads in children by increasing the easiness of reading textbooks due to their compliance with the age peculiarities of students.

[Joint contractures in nursing textbooks].

Bartoszek, G; Meyer, G; Thiesemann, R

2014-01-01

The transparency criteria of the German statutory health insurance on joint contracture prevention have led to controversies about the appropriate assessment, prevention and treatment as well as to various actions in nursing practice. However, appropriate nursing assessments and proven treatment options are lacking so far. It is unclear whether textbooks on nursing reflect these uncertainties. Search for textbooks on nursing through internet-based search engines and publisher registers, data extraction by one investigator and control by a second. A total of 35 textbooks with contributions on joint contractures were identified of which 25 included a definition, causes/risk factors are presented in 32 textbooks and assessments are presented in 5 books. Most often positioning into a physiological or functional neutral position and passive moving of limbs are recommended as passive prophylaxis. Recommended therapeutic and preventive options do not differ. None of the textbooks reflect that there is a lack of scientific knowledge on the subject. Textbooks on nursing do not deal with complete and scientific sound information on joint contractures.

In the textbooks for the elementary school from the sixth to ninth grade, students acquire knowledge of the migrations by the inductive approach. Difficulty level of treatment and quantity of information are increasing by the age level. In the grammar school program a trail of gaining knowledge on migration is deductive. Most attention is dedicated to migrations in general geography textbooks. The textbooks for vocational and technical school programs deal with migrations to a lesser extent and with different approaches.

The Slovenian Art History Textbook in Comparison to Polish Textbooks: Authorship and Content, Didactic Structure and Publishing Circumstances

Directory of Open Access Journals (Sweden)

Marjana Dolšina

2014-09-01

Full Text Available The paper analyses two concepts of art history textbooks for secondary schools. It discusses their role in the learning and teaching process of art history and related school subjects within the formal educational programmes in Slovenia and their didactic structure. The comparison between one Slovenian and two Polish textbooks might contribute to better understanding of the present situation regarding art history textbook production in Slovenia, which is a result of several factors: the historical continuity of textbook writing and research in textbook didactics, the current school policy and financial competition on the textbook market. Its intention is also to clarify the idea of didactic transformation of the art history contents from the challenging scientific texts to a form suitable for secondary school students who are textbooks' main target audience.

This research sought to determine how well the causes of addiction, addiction harms, and prevention of addiction have been noticed in high school textbooks. We used descriptive method to select the main related components of the addiction concept and content analysis method for analyzing the content of textbooks. The study population comprised 61 secondary school curriculum textbooks and study sample consisted of 14 secondary school textbooks selected by purposeful sampling method. The tools for collecting data were "content analysis inventory" which its validity was confirmed by educational and social sciences experts and its reliability has been found to be 91%. About 67 components were prepared for content analysis and were divided to 3 categories of causes, harms, and prevention of addiction. The analysis units in this study comprised phrases, topics, examples, course topics, words, poems, images, questions, tables, and exercises. Results of the study showed that the components of the addiction concept have presented with 212 remarks in the textbooks. Also, the degree of attention given to any of the 3 main components of the addiction concept were presented as follows: causes with 52 (24.52%) remarks, harm with 89 (41.98%) remarks, and prevention with 71 (33.49%) remarks. In high school textbooks, little attention has been paid to the concept of addiction and mostly its biological dimension were addressed while social, personal, familial, and religious dimensions of addiction have been neglected.

Andrikopoulou, M; Michala, L; Creighton, S M; Liao, L-M

2013-10-01

When a healthy woman expresses concerns about her vulva, the doctor's response should be informed by clinical knowledge. For many doctors, accumulation of such knowledge would have begun with undergraduate teaching and medical textbooks. The aim of this study is to examine the information on female genital morphology in medical textbooks. A total of 59 gynaecology and anatomy textbooks were searched for information on the dimensions of vulval constitutent parts. No textbook gave measurements for all vulval structures. Vaginal length was reported in 21/59 textbooks, clitoral size in 15/59 and labia minora in 1/59. Where measurements appear, they suggest narrower ranges than recent reports. Information of vulval morphology is scanty and inaccurate in medical textbooks. The general lack of professional resources means that doctors may consciously or non-consciously rely upon personal experiences and popular culture to form their opinions, as do their patients.

Comparative analysis of a nontraditional general chemistry textbook and selected traditional textbooks used in Texas community colleges

Science.gov (United States)

Salvato, Steven Walter

The purpose of this study was to analyze questions within the chapters of a nontraditional general chemistry textbook and the four general chemistry textbooks most widely used by Texas community colleges in order to determine if the questions require higher- or lower-order thinking according to Bloom's taxonomy. The study employed quantitative methods. Bloom's taxonomy (Bloom, Engelhart, Furst, Hill, & Krathwohl, 1956) was utilized as the main instrument in the study. Additional tools were used to help classify the questions into the proper category of the taxonomy (McBeath, 1992; Metfessel, Michael, & Kirsner, 1969). The top four general chemistry textbooks used in Texas community colleges and Chemistry: A Project of the American Chemical Society (Bell et al., 2005) were analyzed during the fall semester of 2010 in order to categorize the questions within the chapters into one of the six levels of Bloom's taxonomy. Two coders were used to assess reliability. The data were analyzed using descriptive and inferential methods. The descriptive method involved calculation of the frequencies and percentages of coded questions from the books as belonging to the six categories of the taxonomy. Questions were dichotomized into higher- and lower-order thinking questions. The inferential methods involved chi-square tests of association to determine if there were statistically significant differences among the four traditional college general chemistry textbooks in the proportions of higher- and lower-order questions and if there were statistically significant differences between the nontraditional chemistry textbook and the four traditional general chemistry textbooks. Findings indicated statistically significant differences among the four textbooks frequently used in Texas community colleges in the number of higher- and lower-level questions. Statistically significant differences were also found among the four textbooks and the nontraditional textbook. After the analysis of

The findings indicated that coordinating conjunctions were the most frequent conjunctions that occurred in the five textbooks followed by subordinating and correlative conjunctions. The ranking of the different types of conjunctions in the Textbook Corpus was similar to that of the reference corpus, BNC. The results also indicated that the textbooks failed to present conjunctions effectively. The findings are expected to help textbook developers or language teachers in developing or adapting learning materials. Keywords: Conjunctions, Textbook evaluation, Distribution patterns

[The early medical textbooks in Korea: medical textbooks published at Je Joong Won-Severance Hospital Medical School].

Science.gov (United States)

Park, H W

1998-01-01

Kwang Hye Won(Je Joong Won), the first western hospital in Korea, was founded in 1885. The first western Medical School in Korea was open in 1886 under the hospital management. Dr. O. R. Avison, who came to Korea in 1893, resumed the medical education there, which was interrupted for some time before his arrival in Korea. He inaugurated translating and publishing medical textbooks with the help of Kim Pil Soon who later became one of the first seven graduates in Severance Hospital Medical School. The first western medical textbook translated into Korean was Henry Gray's Anatomy. However, these twice-translated manuscripts were never to be published on account of being lost and burnt down. The existing early anatomy textbooks, the editions of 1906 and 1909, are not the translation of Gray's Anatomy, but that of Japanese anatomy textbook of Gonda. The remaining oldest medical textbook in Korean is Inorganic Materia Medica published in 1905. This book is unique among its kind that O. R. Avison is the only translator of the book and it contains the prefaces of O. R. Avison and Kim Pil Soon. The publication of medical textbook was animated by the participation of other medical students, such as Hong Suk Hoo and Hong Jong Eun. The list of medical textbooks published includes almost all the field of medicine. The medical textbooks in actual existence are as follows: Inorganic Materia Medica (1905), Inorganic Chemistry (1906), Anatomy I (1906), Physiology (1906), Diagnostics I (1906), Diagnostics II (1907), Obstetrics (1908), Organic Chemistry (1909), Anatomy (1909), and Surgery (1910).

Gender Representation in Elementary Level, African Language Textbooks

Directory of Open Access Journals (Sweden)

Antonia Folarin Schleicher

2004-01-01

Full Text Available Foreign language learners' perceptions and understanding of a target culture(s are affected by the infonnation presented by their teacher(s, textbooks and other instructional materials. This paper focuses on an analysis of gender representation in elementary level, African language textbooks, with a specific concentration on Hausa, Swahili, Yoruba, and Zulu textbooks. Although the study of gender representation in textbooks is not new (see Blankenship, 1984; Clausen, 1982; Neussel, 1977 and others, relatively few authors have focused on gender representation in foreign language textbooks (Graci, 1989; Rifkin, 1998. This study seeks to extend the work of these scholars into the field of African languages. As a result, the present analysis focuses on (1 establishing criteria for evaluating African language textbooks for gender representation; (2 applying these criteria to seventeen different, elementary level, African language textbooks to create a basis for a comparative case study; (3 presenting the findings of a detailed analysis; and ( 4 utilizing the findings to formulate guidelines for future textbook writers.

Sociology of health textbooks and narratives: historical significance.

Science.gov (United States)

Nunes, Everardo Duarte

2016-03-01

This article has as its starting point two central ideas: textbooks as a means of production and dissemination of knowledge and narrative as an approach. After a brief review of studies on health/medical sociology textbooks, I analyze a few of these textbooks from the 1900-2012 period, produced in the United States and England. I have selected eleven textbooks which I thought were representative. In addition to a content analysis, the textbooks are located within the process of constitution of the health/medical sociology with brief references to the biographies of the authors. The textbooks analyzed were classified according to the main narrative features: doctor-centered; interdisciplinary; pedagogical; analytical; almost autobiographical; critical; and synthetic-reflective. In the final remarks, some points about the textbooks, limits and possibilities are presented.

A Faster Algorithm for Computing Straight Skeletons

KAUST Repository

Cheng, Siu-Wing

2014-09-01

We present a new algorithm for computing the straight skeleton of a polygon. For a polygon with n vertices, among which r are reflex vertices, we give a deterministic algorithm that reduces the straight skeleton computation to a motorcycle graph computation in O(n (logn)logr) time. It improves on the previously best known algorithm for this reduction, which is randomized, and runs in expected O(n√h+1log2n) time for a polygon with h holes. Using known motorcycle graph algorithms, our result yields improved time bounds for computing straight skeletons. In particular, we can compute the straight skeleton of a non-degenerate polygon in O(n (logn) logr + r 4/3 + ε ) time for any ε > 0. On degenerate input, our time bound increases to O(n (logn) logr + r 17/11 + ε ).

Do mathematics textbooks cultivate shallow teaching? Applying the TIMSS Video Study criteria to Australian eighth-grade mathematics textbooks

Science.gov (United States)

Vincent, Jill; Stacey, Kaye

2008-04-01

Australian eighth-grade mathematics lessons were shown by the 1999 TIMSS Video Study to use a high proportion of problems of low procedural complexity, with considerable repetition, and an absence of deductive reasoning. Using definitions from the Video Study, this study re-investigated this `shallow teaching syndrome' by examining the problems on three topics in nine eighth-grade textbooks from four Australian states for procedural complexity, type of solving processes, degree of repetition, proportion of `application' problems and proportion of problems requiring deductive reasoning. Overall, there was broad similarity between the characteristics of problems in the textbooks and in the Australian Video Study lessons. There were, however, considerable differences between textbooks and between topics within textbooks. In some books, including the best-selling textbooks in several states, the balance is too far towards repetitive problems of low procedural complexity.

Pragmatic Content in Global and Local ELT Textbooks

Hussein Meihami

2015-11-01

Full Text Available This study is an attempt to explore the frequency of pragmatic content occurrence represented as three speech acts of requesting, refusing, and apologizing in global and local English Language Teaching (ELT textbooks. Three global elementary ELT textbooks, namely Interchange, Top Notch, and American English File along with the local elementary textbooks of Iran Language Institute (ILI Series, were examined for their pragmatic content. To analyze the pragmatic content of these textbooks, the researchers used three different frameworks. The results indicated that while both global and local ELT textbooks shared a sufficient number of speech acts of request and refusal, they failed to pay enough attention to the speech act of apology regarding its frequency and the strategies through which it is performed. To sum, the findings of this study highlight the differences in the frequency of different speech acts and the strategies used to perform them in global and local elementary ELT textbooks, which bear some implications for ELT textbook developers and language instructors.

The axis of the non-diffracting beam produced by an axicon is very stable and can be adopted as the datum line to measure the spatial straightness error in continuous working distance, which may be short, medium or long. Though combining the non-diffracting beam datum-line with LVDT displace detector, a new straightness error measurement method is developed. Because the non-diffracting beam datum-line amends the straightness error gauged by LVDT, the straightness error is reliable and this method is matchs new generation GPS

Gjunsburgs, B.; Bulankina, V.

2017-10-01

The equilibrium stage of scour at the head of straight guide banks with a uniform and stratified bed conditions have been studied. The contraction of the river by bridge crossing with straight guide banks considerably alters the flow pattern. The streamlines become curve and the concentration of streamlines, longitudinal and transverse slopes of the water surface, a local increase in velocity, vortex and eddy structures, and the origin of a flow separation zone between the extreme streamlines and the guide bank are observed and local scour is developing at the head of the straight guide banks. New formulae for calculation of equilibrium depth of scour at straight guide banks at uniform and stratified river bed is elaborated and confirmed by tests and computer modelling results.

Trickle-down evolution: an approach to getting major evolutionary adaptive changes into textbooks and curricula.

Science.gov (United States)

Padian, Kevin

2008-08-01

Although contemporary high school and college textbooks of biology generally cover the principles and data of microevolution (genetic and populational change) and speciation rather well, coverage of what is known of the major changes in evolution (macroevolution), and how the evidence is understood is generally poor to nonexistent. It is critical to improve this because acceptance of evolution by the American public rests on the understanding of how we know what we know about the emergence of major new taxonomic groups, and about their adaptations, behaviors, and ecologies in geologic time. An efficient approach to this problem is to improve the illustrations in college textbooks to show the consilience of different lines of fossil, morphological, and molecular evidence mapped on phylogenies. Such "evograms" will markedly improve traditional illustrations of phylogenies, "menageries," and "companatomies." If "evograms" are installed at the college level, the basic principles and evidence of macroevolution will be more likely taught in K-12, thus providing an essential missing piece in biological education.

TEXTBOOK ANALYSIS IN THE SERVICE OF CHEMISTRY TEACHING

Directory of Open Access Journals (Sweden)

Aija Ahtineva

2005-06-01

Full Text Available The authors of textbooks have their own visions of contents and teaching methods, which should lead to a high level of scientific thinking. However, the textbook alone does not guarantee good results because the personal and social relationships between the teacher and students have a major influence on teaching and learning. Therefore, the teacher’s study of the textbook before teaching facilitates the teaching process. This paper suggests one method of textbook analysis. In the analysis, one upper secondary level course of chemistry instruction involved the use of a learning strategy: classification of the central concepts and a classification of activities based on task difficulty. The study also attempted to find out the goodness of fit between the national curriculum and the textbook chemistry course. The national objectives concerned the content of knowledge, social significance, emphasis on experimental chemistry, and inspiring students for further study. The majority of the textbook tasks fall into higher order categories characterized by knowledge structures assuming application of knowledge or making inferences. Good textbook activities also have social significance, and a number of experimental tasks are included. The textbook quality is further enhanced by up-to-date content. All of the above qualities are related to high study motivation.

Weiner, Brittany A; Zinner, Leah

2015-01-01

This study examined American attitudes toward transsexual and gay male parenting, compared to straight parenting. After reporting levels of transphobia, participants read a vignette regarding a couple seeking child adoption. Individuals high in transphobia perceived nontraditional couples as more emotionally unstable than straight couples and were less willing to grant custody of a child to the nontraditional couples vs. the straight couples. In addition, the transsexual couple faced more prejudice and discrimination than the gay male couple. Implications of these findings are discussed.

Digital textbooks are increasing in popularity, often resulting from the perception that students demand the use of technology in academics. However, few studies have been done on student perceptions of digital textbooks. A pilot study was conducted with students enrolled in a nursing research course; 123 nursing students participated. This study found that students overwhelmingly preferred print textbooks over digital textbooks. More research needs to be done before assuming students would prefer digital textbooks over print.

THE REPRESENTATIONS OF TYPE OF DISABILITY, ETHNICITY AND AGE AND HOW THESE ARE ASSOCIATED WITH PARTICIPATION IN TEXTBOOKS

Directory of Open Access Journals (Sweden)

Monica REICHENBERG

2017-10-01

Full Text Available Introduction Textbooks matter for an inclusive education. I examined the way in which 30 textbooks in history, religion, civics, and biology represent disability-related issues. Aim: The overall aim is to find out if textbooks represent the type of disability in association with age, ethnicity, and participation. Specifically, this research addresses the question: Are textbooks’ representations of the type of disability, age, and ethnicity associated with participation? By participation I refer to whether textbooks represent people with disabilities as (a engaged in daily activities located outside of institutionalized residence. Engagement in activities may be indicated by sports, being a wage earner, voting, protesting, spending time with family or friends or (b only being at their institutionalized residence/flat. Methods: I examined three hypotheses regarding representations of type of disability, ethnicity, and age and how these are associated with participation. I analysed the data using a combination of qualitative coding of the content as well as qualitative comparative analysis (QCA. Results: Although most textbooks do mention disability, people with a disability remain largely invisible, and less than half of the textbooks represent people with disabilities as active participants. Conclusions: First, I demonstrate that physical disability is associated with active participation. Second, I demonstrate that disability is associated with ethnic majority. Third, I demonstrate that the participation of people with disabilities is associated with both young and old age groups.

Breastfeeding information in pharmacology textbooks: a content analysis.

Science.gov (United States)

Amir, Lisa H; Raval, Manjri; Hussainy, Safeera Y

2013-07-01

Women often need to take medicines while breastfeeding and pharmacists need to provide accurate information in order to avoid undue caution about the compatibility of medicines and breastfeeding. The objective of this study was to review information provided about breastfeeding in commonly used pharmacology textbooks. We asked 15 Australian universities teaching pharmacy courses to provide a list of recommended pharmacology textbooks in 2011. Ten universities responded, generating a list of 11 textbooks that we analysed for content relating to breastfeeding. Pharmacology textbooks outline the mechanisms of actions of medicines and their use: however, only a small emphasis is placed on the safety/compatibility of medicines for women during breastfeeding. Current pharmacology textbooks recommended by Australian universities have significant gaps in their coverage of medicine use in breastfeeding. Authors of textbooks should address this gap, so academic staff can recommend texts with the best lactation content.

Evaluating Junior Secondary Science Textbook Usage in Australian Schools

Science.gov (United States)

McDonald, Christine V.

2016-08-01

A large body of research has drawn attention to the importance of providing engaging learning experiences in junior secondary science classes, in an attempt to attract more students into post-compulsory science courses. The reality of time and resource constraints, and the high proportion of non-specialist science teachers teaching science, has resulted in an overreliance on more transmissive pedagogical tools, such as textbooks. This study sought to evaluate the usage of junior secondary science textbooks in Australian schools. Data were collected via surveys from 486 schools teaching junior secondary (years 7-10), representing all Australian states and territories. Results indicated that most Australian schools use a science textbook in the junior secondary years, and textbooks are used in the majority of science lessons. The most highly cited reason influencing choice of textbook was layout/colour/illustrations, and electronic technologies were found to be the dominant curricula material utilised, in addition to textbooks, in junior secondary science classes. Interestingly, the majority of respondents expressed high levels of satisfaction with their textbooks, although many were keen to stress the subsidiary role of textbooks in the classroom, emphasising the textbook was `one' component of their teaching repertoire. Importantly, respondents were also keen to stress the benefits of textbooks in supporting substitute teachers, beginning teachers, and non-specialist science teachers; in addition to facilitating continuity of programming and staff support in schools with high staff turnover. Implications from this study highlight the need for high quality textbooks to support teaching and learning in Australian junior secondary science classes.

Straight leg elevation to rule out pelvic injury.

Bolt, Caroline; O'Keeffe, Francis; Finnegan, Pete; Dickson, Kristofer; Smit, De Villiers; Fitzgerald, Mark C; Mitra, Biswadev

2018-02-01

Pelvic x-ray is frequently used as a screening tool during initial assessment of injured patients. However routine use in the awake and alert blunt trauma patient may be questioned due to low yield. We propose a clinical tool that may avoid unnecessary imaging by examining whether the ability to straight leg raise, without pain, can rule out pelvic injury. We conducted a prospective cohort study with the exposure variables of ability to straight leg raise and presence of pain on doing so, and presence of pelvic fracture on x-ray as the primary outcome variable. Of the 328 participants, 35 had pelvic fractures, and of these 32 were either unable to straight leg raise, or had pain on doing so, with a sensitivity of 91.43% (95% CI: 76.94-98.2%) and a negative predictive value of 98.57% (95% CI: 95.88-99.70%). The 3 participants with a pelvic fracture who could straight leg raise with no pain, all had a GCS of less than 15, and therefore, among the sub-group of patients with GCS15, a 100% sensitivity and 100% negative predictive value for straight leg raise with no pain to rule out pelvic fracture was demonstrated. Among awake, alert patients, painless straight leg raise can exclude pelvic fractures and be incorporated into initial examination during reception and resuscitation of injured patients.

2016-01-01

Full Text Available The aim of this paper is to define textbooks, analyze their advantages and disadvantages and to explicate the process of textbook selection and reasons for analyzing textbooks. The paper describes two reasons for performing a textbook analysis: evaluating for potential and evaluating for suitability, and further states various processes of textbook content analysis including the analysis of the stated aims and objectives, learner needs, their abilities and preferences, as well as the establishment of criteria in relation to previously set objectives. The paper concludes by stating that the task that teachers are faced with when selecting and evaluating textbooks is not that is an easy one, but it is crucial. With the assistance of clear guidelines and detailed criteria, they should be able to make an informed decision and choose a textbook that is most suitable for the requirements of their specific classroom context.

The text of Bernardino Quijada marked a landmark and polarized to those in favor and detractors during half century. The evolutionary subject was reduced in second half of century XX, partly by the development of other biological fields, but also by ideological pressures of preservative religious sectors. During the last reforms, evolutionary theory oscillates between the compulsory and the optative contents of the programs of Chilean secondary education.

Classical and spatial stochastic processes with applications to biology

CERN Document Server

Schinazi, Rinaldo B

2014-01-01

The revised and expanded edition of this textbook presents the concepts and applications of random processes with the same illuminating simplicity as its first edition, but with the notable addition of substantial modern material on biological modeling. While still treating many important problems in fields such as engineering and mathematical physics, the book also focuses on the highly relevant topics of cancerous mutations, influenza evolution, drug resistance, and immune response. The models used elegantly apply various classical stochastic models presented earlier in the text, and exercises are included throughout to reinforce essential concepts. The second edition of Classical and Spatial Stochastic Processes is suitable as a textbook for courses in stochastic processes at the advanced-undergraduate and graduate levels, or as a self-study resource for researchers and practitioners in mathematics, engineering, physics, and mathematical biology. Reviews of the first edition: An appetizing textbook for a f...

Oku, Hidehisa; Matsubara, Kayoko; Booka, Masayuki

2015-01-01

Digital textbooks have been expected for providing multimedia information that the print textbooks could not handle. The original digital textbook can be fabricated relatively easily by using Epub or DAISY. Print textbooks are, however, employed as textbooks in the most of lectures in universities. Therefore, it is considered necessary to convert the content of the print textbook to the digital textbook simply and in a short time. In this paper, the digital textbook using PDF files of the print textbook was suggested as one of simple and practical solution to provide an alternative textbook for the physically disabled university student who has difficulty handling the print textbook. Then usability of the suggested method was evaluated experimentally from the point of workload. Result of the experiment indicates that the digital textbook fabricated as the alternative one for the print textbook by the suggested method has a potential to reduce workload for the physically disabled university students. In addition, the digital textbook with larger LCD display needs less workload than the print textbook. Then, there are not so much difference in the workload between the print book which is smaller than the print textbook and the digital book made from the print book.

2015-01-01

Utilizing invisible 2-dimensional codes and digital audio players with a 2-dimensional code scanner, we developed paper-based textbooks with audio support for students with print disabilities, called "multimodal textbooks." Multimodal textbooks can be read with the combination of the two modes: "reading printed text" and "listening to the speech of the text from a digital audio player with a 2-dimensional code scanner." Since multimodal textbooks look the same as regular textbooks and the price of a digital audio player is reasonable (about 30 euro), we think multimodal textbooks are suitable for students with print disabilities in ordinary classrooms.

Visual straight-ahead preference in saccadic eye movements.

Science.gov (United States)

Camors, Damien; Trotter, Yves; Pouget, Pierre; Gilardeau, Sophie; Durand, Jean-Baptiste

2016-03-15

Ocular saccades bringing the gaze toward the straight-ahead direction (centripetal) exhibit higher dynamics than those steering the gaze away (centrifugal). This is generally explained by oculomotor determinants: centripetal saccades are more efficient because they pull the eyes back toward their primary orbital position. However, visual determinants might also be invoked: elements located straight-ahead trigger saccades more efficiently because they receive a privileged visual processing. Here, we addressed this issue by using both pro- and anti-saccade tasks in order to dissociate the centripetal/centrifugal directions of the saccades, from the straight-ahead/eccentric locations of the visual elements triggering those saccades. Twenty participants underwent alternating blocks of pro- and anti-saccades during which eye movements were recorded binocularly at 1 kHz. The results confirm that centripetal saccades are always executed faster than centrifugal ones, irrespective of whether the visual elements have straight-ahead or eccentric locations. However, by contrast, saccades triggered by elements located straight-ahead are consistently initiated more rapidly than those evoked by eccentric elements, irrespective of their centripetal or centrifugal direction. Importantly, this double dissociation reveals that the higher dynamics of centripetal pro-saccades stem from both oculomotor and visual determinants, which act respectively on the execution and initiation of ocular saccades.

Straight eye for the gay guy: composing queerness.

Science.gov (United States)

Alexander, Jonathan

2010-01-01

Drawing on the work of Didier Eribon and his theorization of the construction of gay male subjectivity, this article examines different "texts," broadly defined, that grapple specifically with straight men attempting to represent male homosexuality: Norman Mailer's essay, "The Homosexual Villain"; the Bravo reality television series Boy Meets Boy, and Michael Griffith's short story, "Hooper Gets a Perm." These texts represent attempts by straight authors to grapple with queer experience in ways that move the imagination of queers beyond simple stereotypes or uncritical explorations of the sexual "other." In the process of examining these texts, the following questions are addressed: What happens when a straight man attempts to represent a gay man? Does he "get it right," and is such a question even useful? More specifically, what is the value in having straights imagine queerness? Is such an imagining possible? Is such desirable? And, if so, what are the contours of such an imagining-as well as its possibilities and limitations, pedagogically, personally, and politically? Ultimately, I contend that the straight imagining of queerness offers rich potential for mutual understanding; furthermore, attempting to understand what goes into the making of those representations tells us much about how queerness circulates in our culture as a subject, a figure of discussion, contention, and representation.

Ways of incorporating photographic images in learning and assessing high school biology: A study of visual perception and visual cognition

Science.gov (United States)

Nixon, Brenda Chaumont

This study evaluated the cognitive benefits and costs of incorporating biology-textbook and student-generated photographic images into the learning and assessment processes within a 10th grade biology classroom. The study implemented Wandersee's (2000) 20-Q Model of Image-Based Biology Test-Item Design (20-Q Model) to explore the use of photographic images to assess students' understanding of complex biological processes. A thorough review of the students' textbook using ScaleMaster R with PC Interface was also conducted. The photographs, diagrams, and other representations found in the textbook were measured to determine the percentage of each graphic depicted in the book and comparisons were made to the text. The theoretical framework that guided the research included Human Constructivist tenets espoused by Mintzes, Wandersee and Novak (2000). Physiological and cognitive factors of images and image-based learning as described by Robin (1992), Solso (1997) and Wandersee (2000) were examined. Qualitative case study design presented by Yin (1994), Denzin and Lincoln (1994) was applied and data were collected through interviews, observations, student activities, student and school artifacts and Scale Master IIRTM measurements. The results of the study indicate that although 24% of the high school biology textbook is devoted to photographic images which contribute significantly to textbook cost, the teacher and students paid little attention to photographic images other than as aesthetic elements for creating biological ambiance, wasting valuable opportunities for learning. The analysis of the photographs corroborated findings published by the Association American Association for the Advancement of Science that indicated "While most of the books are lavishly illustrated, these representations are rarely helpful, because they are too abstract, needlessly complicated, or inadequately explained" (Roseman, 2000, p. 2). The findings also indicate that applying the 20-Q

Uncertainty of spatial straightness in 3D measurement

2005-01-01

The least-square method is commonly employed to verify the spatial straightness in actual three-dimensional measurement process, but the uncertainty of the verification result is usually not given by the coordinate measuring machines. According to the basic principle of spatial straightness least-square verification and the uncertainty propagation formula given by ISO/TS 14253-2, a calculation method for the uncertainty of spatial straightness least-square verification is proposed in this paper. By this method, the coefficients of the line equation are regarded as a statistical vector, so that the line equation, the result of the spatial straightness verification and the uncertainty of the result can be obtained after the expected value and covariance matrix of the vector are determined. The method not only assures the integrity of the verification result, but also accords with the requirement of the new generation of GPS standards, which can improve the veracity of verification

The book is a textbook (with many exercises) giving an in-depth account of the practical use of mathematical modelling in the biomedical sciences. The mathematical level required is generally not high and the emphasis is on what is required to solve the real biological problem. The subject matter is drawn, e.g. from population biology, reaction kinetics, biological oscillators and switches, Belousov-Zhabotinskii reaction, reaction-diffusion theory, biological wave phenomena, central pattern generators, neural models, spread of epidemics, mechanochemical theory of biological pattern formation and importance in evolution. Most of the models are based on real biological problems and the predictions and explanations offered as a direct result of mathematical analysis of the models are important aspects of the book. The aim is to provide a thorough training in practical mathematical biology and to show how exciting and novel mathematical challenges arise from a genuine interdisciplinary involvement with the biosci...

In order to assess spatial straightness error matched new generation Dimensional Geometrical Product Specification and Verification (GPS), the theory of spatial straightness error assessing is proposed and its advantages are analyzed based on metrology and statistics in this paper. Then, the assessing parameter system is proposed and it is testified in real application comparing to assessment result of the geometric tolerance theory. Statistical parameters of this assessing system post the different characteristics of spatial straightness error, and can reveal the impact of spatial straightness error on the accessory function more roundly to complement the single assessing parameter of geometrical tolerance for straightness error. The statistical spatial straightness tolerance and statistical spatial straightness error proposed in this paper is possible to be applied in evaluation of other error of form, orientation, location and run-out

Transforming "Ecosystem" from a Scientific Concept into a Teachable Topic: Philosophy and History of Ecology Informs Science Textbook Analysis

Science.gov (United States)

Schizas, Dimitrios; Papatheodorou, Efimia; Stamou, George

2017-04-01

This study conducts a textbook analysis in the frame of the following working hypothesis: The transformation of scientific knowledge into school knowledge is expected to reproduce the problems encountered with the scientific knowledge itself or generate additional problems, which may both induce misconceptions in textbook users. Specifically, we describe four epistemological problems associated with how the concept of "ecosystem" is elaborated within ecological science and we examine how each problem is reproduced in the biology textbook utilized by Greek students in the 12th grade and the resulting teacher and student misunderstandings that may occur. Our research demonstrates that the authors of the textbook address these problems by appealing simultaneously to holistic and reductionist ideas. This results in a meaningless and confused depiction of "ecosystem" and may provoke many serious misconceptions on the part of textbook users, for example, that an ecosystem is a system that can be applied to every set of interrelated ecological objects irrespective of the organizational level to which these entities belong or how these entities are related to each other. The implications of these phenomena for science education research are discussed from a perspective that stresses the role of background assumptions in the understanding of declarative knowledge.

Radical heterosexuality: Straight teacher activism in schools : Does ally-led activism work?

Directory of Open Access Journals (Sweden)

Leigh Potvin

2016-06-01

Here, I explore the efficacy of straight teacher allies, the importance of understanding straight privilege, and the significance of radical heterosexuality for straight people doing LGBTQ activism. Relying on queer theory and decolonizing/Indigenous queer theory, I argue that it is necessary for straight teachers to acknowledge their straight privilege in order to challenge homophobia's companions: heterosexism and heteronormativity. In addressing the latter two covert forms of oppression in schools, teachers and students could shift into deeper, more effective resistance measures.

A Thorough Scrutiny of ELT Textbook Evaluations: A Review Inquiry

Directory of Open Access Journals (Sweden)

Reza Gholami

2017-07-01

Full Text Available It is thoroughly agreed that English language textbooks stand amongst the foremost components in any language classrooms worldwide, being referred to as valid, beneficial and labor-saving tools to fulfill an extensive range of needs. An ELT textbook is not merely a set of sheets of paper fastened together to hinge at one side, but is the beating heart of any education system whereupon the whole learning revolves. Notwithstanding their interminable benefits, it is admitted that still the compiled textbooks, especially the ones prescribed in Educational systems have to be evaluated and assessed to confirm whether they fulfil the objectives they are meant for or not, as it is said no perfect textbook exists. Having dealt with evaluation in general, this research meticulously elaborates on textbook evaluation more specifically concluding that there is a dearth of inquiry on textbook selection and evaluation. Afterwards, this research introduces the most common approaches for evaluating ELT textbooks and materials. The paper culminates with concluding remarks and implications, hoping to shed light on how textbook evaluation is practiced worldwide.

Results of a Textbook Survey Given in Introductory Astronomy

Science.gov (United States)

Willoughby, Shannon

2007-05-01

Textbooks are required for virtually all college science courses taught around the country, but whether students use them and find them valuable is not clear. In order to get a better idea about what the students thought of the textbook and how they spent their time using it, an anonymous survey was taken by 305 (out of 400) students enrolled in Physics 101 during the Fall semester of 2005. Developed and administered by www.textrev.com, this is a free survey that college faculty may use for physics and chemistry textbooks. This survey revealed two interesting points. First, although 75% of the students found the textbook to be moderately to very challenging, only 38% of students reported spending 2 or more hours per week reading the text. Reading was assigned the majority of class periods, with the intention that they would read the material before it was covered in class. Second, 81% of the students found that the end of chapter problems were moderately to very challenging, but 62% reported spending one hour or less per week working on the assigned questions. Homework was assigned regularly from the textbook for the first half of the class, after which point we experimented with an online homework system. Next semester a new textbook is being adopted for this class, which has no color pictures and is significantly slimmer than the current textbook. This textbook survey will be given again at the end of next semester to look for any changes in textbook usage.

Sex division of labour in Syrian school textbooks

Science.gov (United States)

Alrabaa, Sami

1985-12-01

The sexist division of labour, particularly in the occupational sector, which is believed to be more eminent in developing countries than in the developed ones, is reinforced by school textbooks. This state of affairs is hampering sex-role equality on the way to emancipation. Various Syrian school textbooks have been scrutinized and proved to be malebiased in content and language. Despite quantitative growth of education, the emancipatory quality of the school textbooks leaves much to be desired. The government has had the chance since 1963 to produce textbooks conductive to its promise of sex-role equality in education. The textbooks portray males for a bustling world of decision making, while conditioning the females to seek fulfilment in the background where servitude and support are the only requirement. Females are derogated and victimized. These contents, which are internalized at school and reproduced in society, certainly do not serve development. The exclusion of one-half of the population from contributing to the tasks of development is a waste of human talent which no society can afford. Furthermore, the sexist portrayal of females in Syrian textbooks is a pale reflection of Arab women in Arab history and literature.

Scientific explanations in Greek upper secondary physics textbooks

Science.gov (United States)

Velentzas, Athanasios; Halkia, Krystallia

2018-01-01

In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the explanandum is a logical consequence of the explanans, which in all cases include at least one scientific law (and/or principle, model or rule) previously presented, as well as statements concerning a specific case or specific conditions. The same structure is also followed in most of the cases in which the textbook authors explain regularities (i.e. laws, rules) as consequences of one or more general law or principle of physics. Finally, a number of the physics laws and principles presented in textbooks are not deduced as consequences from other, more general laws, but they are formulated axiomatically or inductively derived and the authors argue for their validity. Since, as it was found, the scientific explanations presented in the textbooks used in the study have similar structures to the explanations in internationally known textbooks, the findings of the present work may be of interest not only to science educators in Greece, but also to the community of science educators in other countries.

Motivating students to read the textbook before class

Science.gov (United States)

Pepper, Rachel E.

2016-11-01

Many faculty in STEM courses assign textbook reading in advance of lecture, yet evidence shows few students actually read the textbook. Those students that do read often do so only after the material has been presented in class. Preparing for class by reading the textbook beforehand improves student learning and is particularly critical for classes that employ active engagement strategies. Here I present strategies I have used to successfully motivate my students to read the textbook before class in physics classes ranging from introductory algebra-based physics to advanced courses for physics majors. In the introductory course, I used pre-class reading quizzes, a common strategy that has been shown effective in previous studies, but one that is somewhat time-consuming to implement. In my more advanced courses I used reading reflections, which required considerably less time. While it was typical for less than 25% of students to read the textbook before I implemented reading quizzes or reflections, after implementing these strategies 70-90% of students reported reading the textbook before class most of the time. Students also report finding both the readings themselves and the quizzes and reflections valuable for their learning.

Full Text Available This research is an exploratory study that investigates students’ perceptions pertinent to textbook layout and organization and their evaluation of the textbook ease of learning. The objective is to find out whether the layout dynamics of school textbooks make any difference in students’ interest in studying or subject understanding. 73 students from various private schools of Pakistan’s cosmopolitan city Karachi responded to a quantitative survey that gauged their perceptions regarding textbook components such as paper, print, color, and textbook pedagogical features. Findings indicate that students rank print and color above paper quality, and that there is no particular relationship between a book layout and the actual use of textbooks.

Gender bias in Islamic textbooks for Muslim children in Indonesia

Directory of Open Access Journals (Sweden)

Suwardi Suwardi

2018-01-01

Full Text Available Textbook has a strong influence on the formation of children’s attitudes and value system. Therefore, Islamic textbooks as the main learning source for Muslim children in Indonesia need to consider the gender equality. This is very important to note, because feminists often view that Islam contains teachings of gender inequality. Islam places men in the higher position, while women are placed in the lower position. For example, men can be imam for women in prayer, but women cannot be imam for men. It is easier for children to learn textbook material presented in pictures. Therefore, the pictures presented in Islamic textbooks ideally do not contain gender bias. So, a research is needed to know if there is gender bias in the pictures presented in Islamic textbooks taught to Muslim children in Indonesia. To prove it, a literary research is conducted on the Islamic textbooks taught to the first grade Muslim student of Islamic Elementary School/ Madrasah Ibtidaiyah (MI in Indonesia which includes pictures in their teaching materials. Islamic textbooks studied in the research include Fikih, Akidah Akhlak, and Arabic textbooks. The results of this study conclude that the pictures presented in Islamic textbooks taught in Muslim children in Indonesia contain gender bias. The man favor pictures are more than those of woman favor. Based on the conclusion, this study recommends an improvement of pictures presented in Islamic textbooks taught to Muslim children in Indonesia.

2015-10-01

The aim of this study was to evaluate bent and straight phacoemulsification tips to determine which tip is more efficient in removal of lens fragments, using micropulsed longitudinal ultrasound in phacoemulsification. In vitro laboratory study. The John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, was the study setting. Pig lenses hardened in a manner comparable with dense human cataracts were cut into 2-mm cubes and removed with micropulsed longitudinal ultrasound using settings previously shown to be optimally efficient (6 milliseconds on and 6 milliseconds off for a bent tip). To verify this time as most efficient for a straight tip, we also tested times of 5, 6, and 7 milliseconds time on and off. The tips were either straight or with a 20-degree bend. Twenty cubes were used for each comparative run. For the straight tip, 6 milliseconds on (1.56 ± 0.815 seconds) was significantly more efficient than 7 milliseconds on (2.45 ± 1.56 seconds, p = 0.001) and not significantly more efficient than 5 milliseconds on (1.69 ± 0.86 seconds, p = 0.43). Five milliseconds off time (1.45 ± 0.76s) was more efficient than 6 milliseconds (2.06 ± 1.37 seconds, p = 0.004) and 7 milliseconds off (2.18 ± 1.24s, p = 0.001). The straight tip was more efficient than the bent tip (1.38 ± 0.83 versus 2.93 ± 2.14 seconds, p = 0.006). Results are contrary to accepted common belief. Micropulsed longitudinal phacoemulsification is more efficient with a straight rather than a bent tip. Copyright © 2015 Canadian Ophthalmological Society. Published by Elsevier Inc.

Sandia National Laboratories is developing Straight-Line -- a pilot system to demonstrate comprehensive monitoring of nuclear material in storage. Straight-Line is an integrated system of sensors providing information that will enhance the safety, security, and international accountability of stored nuclear material. The goals of this effort are to: (1) Provide the right sensor information to the right user immediately. (2) Reduce the expenses, risks, and frequency of human inspection of the material. (3) Provide trustworthy data to international inspectors to minimize their need to make on site inspections. In pursuit of these goals, Straight-Line unites technology from Sandia's Authenticated Item Monitoring System (AIMS) and other programs to communicate the authenticated status of the monitored item back to central magazine receivers. Straight-Line, however, incorporates several important features not found in previous systems: (1) Information Security -- the ability to collect and safely disseminate both classified and unclassified sensor data to users on a need-to-know basis. (2) Integrate into a single system the monitoring needs of safety, security, and international accountability. (3) Incorporate the use of sensors providing analog or digital output. This paper will present the overall architecture and status of the Straight-Line project

Full Text Available Research in materials evaluation has been an important focus in ELT since the 1980s. The objective of the present study is to evaluate the general attributes of the textbooks and to evaluate the learning-teaching content. In this study, 944 male and female English teachers (Year 1 to Year 6 & Form 1 to Form 5 evaluated the English books using a valid and reliable checklist. In terms of general attributes and learning-teaching content of the textbooks, the results showed that Year 1 to Year 6 teachers reported that the current textbooks are ‘highly useful’ to the students, whereas Form 1 to Form 5 teachers contended that the school books are only ‘moderately useful’. The findings of this study can be useful for curricula designers and Ministry of Education as a reference for improving or modifying the textbooks.

Secondary-school chemistry textbooks in the 19th century

Directory of Open Access Journals (Sweden)

Milanović Vesna D.

2015-01-01

Full Text Available The teaching of chemistry in Serbia as a separate subject dates from 1874. The first secondary-school chemistry textbooks appeared in the second half of the 19th century. The aim of this paper is to gain insight, by analysing two secondary-school chemistry textbooks, written by Sima Lozanić (1895 and Mita Petrović (1892, into what amount of scientific knowledge from the sphere of chemistry was presented to secondary school students in Serbia in the second half of the 19th century, and what principles textbooks written at the time were based on. Within the framework of the research conducted, we defined the criteria for assessing the quality of secondary-school chemistry textbooks in the context of the time they were written in. The most important difference between the two textbooks under analysis that we found pertained to the way in which their contents were organized. Sima Lozanić’s textbook is characterized by a greater degree of systematicness when it comes to the manner of presenting its contents and consistency of approach throughout the book. In both textbooks one can perceive the authors’ attempts to link chemistry-related subjects to everyday life, and to point out the practical significance of various substances, as well as their toxicness.

Textbooks in transitional countries: Towards a methodology for comparative analysis

Directory of Open Access Journals (Sweden)

Miha Kovač

2004-01-01

Full Text Available In its first part, the paper analyses the ambiguous nature of the book as a medium: its physical production and its distribution to the end user takes place on a market basis; on the other hand, its content is predominantly consumed in a sector that was at least in the continental Europe traditionally considered as public and non-profit making. This ambiguous nature of the book and with it the impact of the market on the organization of knowledge in book format remains a dark spot in contemporary book research. On the other hand, textbooks are considered as ephemera both in contemporary education and book studies. Therefore, research on textbooks publishing models could be considered as a blind-spot of contemporary social studies. As a consequence, in the majority of European countries, textbook publishing and the organization of the textbook market are considered as self-evident. Throughout a comparative analysis of textbook publishing models in small transitional and developed countries, the paper points out that this self-evident organization of the textbook market is always culturally determined. In its final part, the paper compares different models of textbook publishing and outlines the scenarios for the development of the Slovene textbook market.

Straight-Line -- A nuclear material storage information management system

International Nuclear Information System (INIS)

Nilsen, C.; Mangan, D.

1995-01-01

Sandia National Laboratories is developing Straight-Line -- a pilot system to demonstrate comprehensive monitoring of nuclear material in storage. Straight-Line is an integrated system of sensors providing information that will enhance the safety, security, and international accountability of stored nuclear material. The goals of this effort are to (1) Provide the right sensor information to the right user in a timely manner. (2) Reduce the expenses, risks, and frequency of human inspection of the material. (3) Provide trustworthy data to international inspectors to minimize their need to make on site inspections. In pursuit of these goals, Straight-Line unites technology from Sandia's Authenticated Item Monitoring System (AIMS) and other programs to communicate the authenticated status of the monitored item back to central magazine receivers. Straight-Line, however, incorporates several important features not found in previous systems: (1) Information Security -- the ability to collect and safely disseminate both classified and unclassified sensor data to users on a need-to-know basis. (2) Integrate into a single system the monitoring needs of safety, security, and international accountability. (3) Incorporate the use of sensors providing analog or digital output. This paper will present the overall architecture and status of the Straight-Line project

Kaiser, David

2012-03-01

Though the notion of a scientific textbook has been around for almost three centuries, the category has hardly been stable. The plasticity of the textbook genre may be illustrated by recent variations as well as long-term trends. In this brief essay I examine two idiosyncratic but highly successful physics books, each published in the mid 1970s, whose production, marketing, and adoption reveal some of the slippage between such categories as textbook, scholarly monograph, and popular best seller.

Kar, Tuğrul; Güler, Gürsel; Şen, Ceylan; Özdemir, Ercan

2018-02-01

This study analyzed the methods used to teach the multiplication of fractions in Turkish and American textbooks. Two Turkish textbooks and two American textbooks, Everyday Mathematics (EM) and Connected Mathematics 3 (CM), were analyzed. The analyses focused on the content and the nature of the mathematical problems presented in the textbooks. The findings of the study showed that the American textbooks aimed at developing conceptual understanding first and then procedural fluency, whereas the Turkish textbooks aimed at developing both concurrently. The American textbooks provided more opportunities for different computational strategies. The solutions to most problems in all textbooks required a single computational step, a numerical answer, and procedural knowledge. Furthermore, compared with the Turkish textbooks, the American textbooks contained a greater number of problems that required high-level cognitive skills such as mathematical reasoning.

Highly sensitive straightness measurement system using a ball-lens

International Nuclear Information System (INIS)

Lee, Minho; Yang, Hyun-Ik; Cho, Nahm-Gyoo

2016-01-01

In this paper, a new and simple optical technique to accurately measure the straightness errors of a linear stage is proposed. To improve the performance, including the measurement sensitivity and resolution of the measurement system, and to simultaneously measure two-dimensional straightness errors (2D straightness errors), an optical system was designed using a laser, a retro-reflector, a ball-lens, and a two-dimensional position sensitive detector (2D PSD). The characteristics of the measurement system were analytically and experimentally investigated. A prototype measurement system was manufactured based on the investigated results, and the performances of this system have been tested. The measuring performance of the system was easily improved by about 12 times using the proposed technique and it can be further improved. It is shown that the proposed technique can easily and effectively improve the performance of a conventional straightness measurement system based on the geometric optical method using a PSD.

Ratcheting failure of pressurised straight pipes and elbows under reversed bending

International Nuclear Information System (INIS)

Vishnuvardhan, S.; Raghava, G.; Gandhi, P.; Saravanan, M.; Goyal, Sumit; Arora, Punit; Gupta, Suneel K.; Bhasin, Vivek

2013-01-01

Ratcheting studies were carried out on Type 304LN stainless steel straight pipes and elbows subjected to steady internal pressure and cyclic bending load. The internal pressure for all the straight pipes was 35 MPa and in the case of elbows the internal pressure was varied for different elbows, ranging from 27.6 MPa to 39.2 MPa. Cyclic bending load was applied on the specimens by subjecting them to different levels of load-line displacement. The specimens have undergone significant ratchet swelling (ballooning), ovalization and consequent thinning of the cross-section during ratcheting. The straight pipes failed either by occurrence of through-wall crack accompanied by simultaneous ballooning, or bursting with simultaneous ballooning. All the elbows failed by occurrence of through-wall crack accompanied by simultaneous ballooning. Ratcheting behaviour of straight pipes and elbows were compared and it was generally inferred that ratcheting was more pronounced in straight pipes than in elbows. -- Graphical abstract: Strain history for the specimen QCE-RAT-6-L1. Highlights: • Studies were carried out under combined internal pressure and cyclic bending. • Ratcheting strains were measured at critical locations of the specimens. • Quantified the percentage of ballooning, ovalization and reduction in thickness. • Modes of ratcheting failure of straight pipes and elbows are studied. • Inferred that ratcheting is more pronounced in straight pipes than in elbows

As Good or Better than Commercial Textbooks: Students’ Perceptions and Outcomes from Using Open Digital and Open Print Textbooks

Directory of Open Access Journals (Sweden)

Rajiv S. Jhangiani

2018-04-01

Full Text Available The increase in the cost of college textbooks together with the proliferation of digital content and devices has inspired the development of open textbooks, open educational resources that are free, openly licensed, and often peer-reviewed. Although several published studies have investigated the impact of open textbook adoption on educational outcomes, none have separated the effects of textbook openness and format and only two have taken place in Canada (Hendricks, Reinsberg, & Rieger, 2017; Jhangiani & Jhangiani, 2017. This study investigates the perceptions, use, and course performance of Canadian post-secondary students assigned a commercial or open textbook in either print or digital format. Results show that students using the print format of the open textbook perceive its quality to be superior to the commercial textbook. Moreover, students assigned an open textbook in either format perform either no differently from or better than those assigned a commercial textbook. These results are consistent with the existing literature and support the conclusion that the cost savings to students associated with the adoption of open textbooks do not come at the expense of resource quality or student performance. L’augmentation du coût des manuels universitaires ainsi que la prolifération du contenu numérique et des appareils électroniques ont inspiré le développement de manuels ouverts, des ressources éducationnelles qui sont gratuites, dont les licences d’exploitation sont ouvertes et qui sont souvent évalués par les pairs. Bien que plusieurs études publiées aient étudié l’impact de l’adoption de manuels ouverts sur les résultats éducationnels, aucune n’a séparé les effets du caractère ouvert des manuels et du format et seulement deux études ont été menées au Canada (Hendricks, Reinsberg & Rieger, 2017; Jhangiani & Jhangiani, 2017.

2015-06-01

Medical textbooks are an important teaching supplement. Few have junior doctors or medical students ('juniors') as primary contributors. However, the strengths of junior-led face-to-face teaching are now well-established, and we hypothesized that similar advantages would be transferrable to a textbook setting. Juniors were approached to contribute to an independently published medical textbook, with senior clinicians recruited in parallel to ensure factual accuracy. Juniors directed every aspect of textbook writing and the production process. The published book stressed that it was an open collaboration with readers, inviting them to get in touch to evaluate the text and suggest ideas for new titles. Of 75 respondents, 93 % awarded the first textbook in the series 4 or 5 out of 5 for overall quality. Five other titles have been released, with seven more in development. Over 100 juniors are currently involved, with two students progressing from reviewers to editors after less than a year of mentorship. Juniors can be a motivated, dynamic, innovative group, capable of significant contributions to the medical textbook literature. This initiative has generated a sustainable infrastructure to facilitate junior-led publishing, and has the capacity for expansion to accommodate new initiatives and ideas.

Mermelstein, Claudia; Costa, Manoel Luis

2017-04-01

The enormous amount of information available in cell biology has created a challenge in selecting the core concepts we should be teaching our undergraduates. One way to define a set of essential core ideas in cell biology is to analyze what a specific cell biology community is teaching their students. Our main objective was to analyze the cell biology content currently being taught in Brazilian universities. We collected the syllabi of cell biology courses from public universities in Brazil and analyzed the frequency of cell biology topics in each course. We also compared the Brazilian data with the contents of a major cell biology textbook. Our analysis showed that while some cell biology topics such as plasma membrane and cytoskeleton was present in ∼100% of the Brazilian curricula analyzed others such as cell signaling and cell differentiation were present in only ∼35%. The average cell biology content taught in the Brazilian universities is quite different from what is presented in the textbook. We discuss several possible explanations for these observations. We also suggest a list with essential cell biology topics for any biological or biomedical undergraduate course. The comparative discussion of cell biology topics presented here could be valuable in other educational contexts. © 2017 The Authors.

INSTRUCTIONAL MANUALS OF BOUNDARY‐WORK: PSYCHOLOGY TEXTBOOKS, STUDENT SUBJECTIVITIES, AND DISCIPLINARY HISTORIOGRAPHIES

Science.gov (United States)

FLIS, IVAN

2016-01-01

This article aims to provide an overview of the historiography of psychology textbooks. In the overview, I identify and describe in detail two strands of writing histories of introductory textbooks of psychology and juxtapose them to provide an integrated historiography of textbooks in psychology. One strand is developed by teachers of psychology—first as a general approach for investigating textbooks in a pedagogical setting, and then later upgraded into a full history of psychology textbooks in America. The other strand follows a more familiar perspective of historians of science and historians of psychology who build on various post‐Kuhnian and post‐Foucauldian perspectives on textbooks. I make an argument for integrating these two views for a more comprehensive historiography of textbooks in psychology, recasting textbooks as objects of research and sources that are interesting sui generis for historians of psychology in their investigations.

Mees, Steven; Jiménez Bellinga, Raúl; Mommaerts, Maurice Y; De Pauw, Guy A M

2013-12-01

Several investigators have compared the perception of profile attractiveness between professional and non-professional people, different groups of clinicians, and different ethnic groups. Our aim was to study preferences for facial protrusion in the lateral view for a straight Class I profile and to study the influence of gender, age, sex preference, and profession. Portrait images of one male and one female model with a Class I occlusal relationship were warped into nine different antero-posterior positions. An internet site was established to reach as many people as possible, and a request was sent by email to participate in a scientific experiment. Finally, 1707 Caucasion assessors could be grouped. The preferred male profile is the straight full ante profile. For a feminine facial profile, the straight average and the straight 2/3 ante profiles were perceived as the most attractive. Surgeons tended to give significantly higher scores to attractive (ante) profiles, which correlated strongly with scores of the orthodontists. Whenever possible with combined orthodontic/surgery treatment, straight ante profiles should be aimed for. Copyright © 2013 European Association for Cranio-Maxillo-Facial Surgery.

The positron and electron damping rings for the International Linear Collider will contain long straight sections consisting of twenty wiggler/quadrupole pairs. The wigglers will be based upon the CESR superconducting design. There are a number of challenges associated with the design of the wiggler straight vacuum system, in particular, the absorption of photon power generated by the wigglers. This paper will present the overall conceptual design of the wiggler straight vacuum system developed for the ILC Reference Design Report. Particular emphasis will be placed on photon power load calculations and the absorber design

INSTRUCTIONAL MANUALS OF BOUNDARY-WORK: PSYCHOLOGY TEXTBOOKS, STUDENT SUBJECTIVITIES, AND DISCIPLINARY HISTORIOGRAPHIES.

Science.gov (United States)

Flis, Ivan

2016-07-01

This article aims to provide an overview of the historiography of psychology textbooks. In the overview, I identify and describe in detail two strands of writing histories of introductory textbooks of psychology and juxtapose them to provide an integrated historiography of textbooks in psychology. One strand is developed by teachers of psychology-first as a general approach for investigating textbooks in a pedagogical setting, and then later upgraded into a full history of psychology textbooks in America. The other strand follows a more familiar perspective of historians of science and historians of psychology who build on various post-Kuhnian and post-Foucauldian perspectives on textbooks. I make an argument for integrating these two views for a more comprehensive historiography of textbooks in psychology, recasting textbooks as objects of research and sources that are interesting sui generis for historians of psychology in their investigations. © 2016 The Authors.

Replacing textbook problems with lab experiences

Science.gov (United States)

Register, Trevor

2017-10-01

End-of-the-chapter textbook problems are often the bread and butter of any traditional physics classroom. However, research strongly suggests that students be given the opportunity to apply their knowledge in multiple contexts as well as be provided with opportunities to do the process of science through laboratory experiences. Little correlation has been shown linking the number of textbook problems solved with conceptual understanding of topics in mechanics. Furthermore, textbook problems as the primary source of practice for students robs them of the joy and productive struggle of learning how to think like an experimental physicist. Methods such as Modeling Instruction tackle this problem head-on by starting each instructional unit with an inquiry-based lab aimed at establishing the important concepts and equations for the unit, and this article will discuss ideas and experiences for how to carry that philosophy throughout a unit.

Critical analysis of science textbooks evaluating instructional effectiveness

CERN Document Server

2013-01-01

The critical analysis of science textbooks is vital in improving teaching and learning at all levels in the subject, and this volume sets out a range of academic perspectives on how that analysis should be done. Each chapter focuses on an aspect of science textbook appraisal, with coverage of everything from theoretical and philosophical underpinnings, methodological issues, and conceptual frameworks for critical analysis, to practical techniques for evaluation. Contributions from many of the most distinguished scholars in the field give this collection its sure-footed contemporary relevance, reflecting the international standards of UNESCO as well as leading research organizations such as the American Association for the Advancement of Science (whose Project 2061 is an influential waypoint in developing protocols for textbook analysis). Thus the book shows how to gauge aspects of textbooks such as their treatment of controversial issues, graphical depictions, scientific historiography, vocabulary usage, acc...

An innovative textbook: design and implementation.

Science.gov (United States)

Ortega, Rafael; Akhtar-Khavari, Vafa; Barash, Paul; Sharar, Sam; Stock, M Christine

2017-12-01

The 'flipped classroom' instructional strategy has gained much momentum in educational discourse, yet no single educational offering exists in postgraduate medical education (PME) to systematically replace the lecture element of didactic sessions. This article describes the design and implementation of Clinical Anesthesia Fundamentals, the first known textbook in PME addressing this gap in resources through the integration of full-length interactive multimedia-enhanced video lectures. The 'flipped classroom' instructional strategy has gained much momentum in educational discourse INNOVATION: The textbook was developed in alignment with the content outline for the specialty provided by the American Board of Anesthesiology. Its accompanying video lectures, produced at the Media Lab in the Department of Anesthesiology at Boston University Medical Center (BUMC), cover the topics in each chapter of the textbook and include review questions featuring explanatory feedback. Following a 5-month trial period at the BUMC Anesthesiology Residency Program, the complete resident class (25 of 25; 100%) participated in an anonymous, Institutional Review Board (IRB) -approved, five-point Likert-type scale survey assessing an underlying variable of preference for the use of multimedia learning tools. Survey results suggest that residents favour technology-enhanced learning environments in which textbooks are coupled with interactive multimedia, and the 'flipped classroom' approach is employed. Although the development of digital videos requires time and financial investment, the improved accessibility and uniform delivery of didactic content are two positive outcomes. This textbook provides an example for educators wishing to learn how to capitalise on advances in technology to further enhance learning and accessibility. Further studies could address the impact of this approach on the academic performance of residents. © 2016 John Wiley & Sons Ltd and The Association for the Study

Teachers' selection and enactment of mathematical problems from textbooks

Science.gov (United States)

Son, Ji-Won; Kim, Ok-Kyeong

2015-12-01

In order to investigate how teachers' use of textbooks creates different kinds of opportunities for student learning, this study focused on teachers' selection and enactment of problems and tasks from the textbooks and their influence on the cognitive demand placed on students. By drawing on data from three elementary teachers in the USA, two of which used a reform-oriented textbook— Math Trailblazers and one a commercially developed textbook—this study examined kinds of problems the teachers chose and ways in which they enacted those problems in relation to the cognitive demand of the problems. In particular, we attended to the kinds of questions the teachers asked in enacting the problems and ways in which those questions influenced the cognitive demand of the textbook problems. This study also identified critical issues involved in teacher decision-making on task selection and enactment, such as the match between teachers' goals and those of the textbooks, and teachers' perception of textbook problems. Based on the results of the study, we discuss implications for teacher education and professional development.

2016-01-01

Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. Three known textbooks (Ingle's Endodontics, Seltzer and Bender's Dental Pulp and Cohen's Pathways of the Pulp) were chosen and all the editions of the textbooks since 2000 were investigated for quoted Iranian publications. Only Iranian authors with affiliations from a domestic university were chosen. All references at the end of each chapter were read by hand searching, and results were noted. The trend and percentage of Iranian publications in different editions of the textbooks were also calculated. The number of citations of these publications in Google Scholar and Scopus databases were also obtained. The number of Iranian publications in all well-known textbooks have notably increased since 2000. The number and percentage of Iranian publications in the latest edition of Cohen's Pathways of the Pulp was higher compared to other textbooks as well as the previous edition of the same text. Number and percentage of Iranian publications in the field of endodontics in all three textbooks have remarkably increased since 2000.

The intercultural component in Business English textbooks

Directory of Open Access Journals (Sweden)

M. Carmen Lario de Oñate

2013-10-01

Full Text Available The relationship between culture and business is crucial; therefore, in an international business context Intercultural Communicative Competence (ICC is essential for effectively dealing with other cultures. The Common European Framework of Reference for Languages highlights the relevance of intercultural language education in developing effective communication across linguistic and cultural boundaries (Council of Europe, 2001. Thus, in recent years, whereas there has been an increasing interest in Intercultural Business Communication (IBC, relatively little attention has been paid to the study of the intercultural component in texts used for the teaching of English for Business, despite the fact that textbooks are a key resource for language instructors. This paper aims to examine the role that the intercultural component has played in Business English textbooks since the 1960s. It explores whether and to what extent those textbooks have promoted the acquisition of ICC, at the same time it reviews the development of ICC as a concept and the ways in which it has been taught over the years. A selection of 67 general Business English textbooks published between 1963 and 2009 are analysed.

Raising European Citizens: Constructing European Identities in French and English Textbooks

Directory of Open Access Journals (Sweden)

Inari Sakki

2016-06-01

Full Text Available Schools play a pivotal role in the formation of identities and in the political socialization of youth. This study explores the social representations of European integration in French and English school textbooks and shows how the social representations are discursively used to construct national and European identities. By analysing the history and civics textbooks of major educational publishers, this study aims to demonstrate how European integration is understood, made familiar and concretized in the school textbooks of the two influential but different European countries. The findings suggest some shared and some diverse patterns in the way the two European countries portray and construct the political project of European integration. These representations, constructed around French Europe in French textbooks and ambivalent Europe in English textbooks, share the images of a strong European economy and a French-led political Europe. However, they position themselves differently with respect to the United States, motivation for the European unification process and the significance of common values and heritage. In both countries textbooks draw upon memories that are important for group identity. While the French textbooks make European integration meaningful in reference to a shared post-war collective memory and to a cultural memory based on a more ancient idea of Europe, shared values and heritage, the English textbooks anchor it more strongly to domestic policy.

Do textbooks address known learning challenges in area measurement? A comparative analysis

Science.gov (United States)

Hong, Dae S.; Choi, Kyong Mi; Runnalls, Cristina; Hwang, Jihyun

2018-02-01

This study compared area lessons from Korean textbooks and US standard-based textbooks to understand differences and similarities among these textbooks, as well as how these textbooks address known learning challenges in area measurement. Several well-known challenges have been identified in previous studies, such as covering, array structure, and linking array structure to area formula. We were interested in knowing if textbooks addressed these issues in their treatments of area measurement and, in doing so, provided students with opportunities to overcome or become familiar with known challenges. The results show that both countries' textbooks demonstrated similar limitations; only few area and area-related lessons are covered and three important learning challenges in area measurement are not covered well, which need to be informed to practicing teachers.

Local institutionalization, discontinuity, and German textbooks of psychology, 1816-1854.

Science.gov (United States)

Teo, Thomas

2007-01-01

In the context of social and intellectual developments and the changing role of German universities in the first half of the nineteenth century, which led to the local institutionalization of the discipline of psychology at German universities, the structure and content of textbooks of psychology are discussed. Textbooks in the first half of the nineteenth century had a pedagogical function in training teachers, in socializing students into the field, and in providing students and readers with knowledge about the subject matter, methodology, and topics of psychology. The textbooks, representative of influence, philosophical-psychological orientations, and different decades in the first half of the nineteenth century, are reconstructed with regard to the definition of psychology, the ways of studying the soul, and how to conceptually organize the field. The textbooks by Herbart, Beneke, and Waitz, which were written within a natural-scientific programmatic vision for psychology, are contrasted with the traditional philosophically intended textbooks of Reinhold, Mussmann, George, and Schilling. Fischhaber's textbook for Gymnasien is summarized. Issues regarding the continuity of psychology are discussed, and discontinuous developments in the history of German psychology are identified.

Student Selection of the Textbook for an Introductory Physics Course

Science.gov (United States)

Dake, L. S.

2007-10-01

Several years ago I had to select a new textbook for my calculus-based introductory physics class. I subscribe to Just-in-Time Teaching methods, which require students to read the book before the material is covered in class. Thus, the readability of the text by the students is critical. However, I did not feel that I was the best judge of this factor, so I turned the textbook selection into a class project. The students unanimously chose one textbook, which I have now successfully used for three years. The project was decidedly worthwhile, and I gained considerable insight into what students prefer in a textbook.

Investigating the Conceptual Variation of Major Physics Textbooks

Science.gov (United States)

Stewart, John; Campbell, Richard; Clanton, Jessica

2008-04-01

The conceptual problem content of the electricity and magnetism chapters of seven major physics textbooks was investigated. The textbooks presented a total of 1600 conceptual electricity and magnetism problems. The solution to each problem was decomposed into its fundamental reasoning steps. These fundamental steps are, then, used to quantify the distribution of conceptual content among the set of topics common to the texts. The variation of the distribution of conceptual coverage within each text is studied. The variation between the major groupings of the textbooks (conceptual, algebra-based, and calculus-based) is also studied. A measure of the conceptual complexity of the problems in each text is presented.

Desegregating undergraduate mathematics and biology--interdisciplinary instruction with emphasis on ongoing biomedical research.

Science.gov (United States)

Robeva, Raina

2009-01-01

The remarkable advances in the field of biology in the last decade, specifically in the areas of biochemistry, genetics, genomics, proteomics, and systems biology, have demonstrated how critically important mathematical models and methods are in addressing questions of vital importance for these disciplines. There is little doubt that the need for utilizing and developing mathematical methods for biology research will only grow in the future. The rapidly increasing demand for scientists with appropriate interdisciplinary skills and knowledge, however, is not being reflected in the way undergraduate mathematics and biology courses are structured and taught in most colleges and universities nationwide. While a number of institutions have stepped forward and addressed this need by creating and offering interdisciplinary courses at the juncture of mathematics and biology, there are still many others at which there is little, if any, interdisciplinary interaction between the curricula. This chapter describes an interdisciplinary course and a textbook in mathematical biology developed collaboratively by faculty from Sweet Briar College and the University of Virginia School of Medicine. The course and textbook are designed to provide a bridge between the mathematical and biological sciences at the lower undergraduate level. The course is developed for and is being taught in a liberal arts setting at Sweet Briar College, Virginia, but some of the advanced modules are used in a course at the University of Virginia for advanced undergraduate and beginning graduate students. The individual modules are relatively independent and can be used as stand-alone projects in conventional mathematics and biology courses. Except for the introductory material, the course and textbook topics are based on current biomedical research.

Image of the Ottomans in Bosnian Textbooks Published After 2007

2015-01-01

Full Text Available Division of historical consciousness in Bosnia and Herzegovina started before the Yugoslav Wars, but this division of historiographies and approaches towards the past resulted with more openly manifestation of the divisions to educational system and history textbooks during the wartime and post Dayton era. Even though International Community tried to change poisonous environment of ethnic hatred in which textbooks are produced, except few successes with Bosniak textbooks, not much positive development was achieved. Reform period which started in 1998 today is seen as an unfinished project. In Bosnia and Herzegovina three different versions of history with two of them having the focus point in neighboring Serbia and Croatia are taught to the students. Besides the fact that students are learning three different histories, there is a certain level of hatred and fear of others spreading through history textbooks. History textbooks became an important tool for poisoning the minds of the youth and building the barriers towards the others. This is the case especially with Serb and Croat textbooks in Bosnia and Herzegovina. Ottoman period in Balkans is mainly seen as a ‘’dark age of the Balkans’’ as it is underlined in one Serbian textbook and to lesser extend in Croat ones. Even though Bosniaks see Ottoman period in more positive light than other two ethnic groups, there are certain topics and periods were it is possible to see romantistic and nationalistic tone towards the Ottomans. History textbooks in Bosnia are having negative contribution for country’s possible future dissolution and it is the one of the main source of stereotype engineering that country is passing in the last decades and which is one of the main reason of the recent wars. In the times where country is confronting with secessionist threat, it is highly important to start building Bosnian statehood and understanding of others through history textbooks, otherwise we can

Spherical Projection Based Straight Line Segment Extraction for Single Station Terrestrial Laser Point Cloud

Directory of Open Access Journals (Sweden)

ZHANG Fan

2015-06-01

Full Text Available Due to the discrete distribution computing errors and lack of adaptability are ubiquitous in the current straight line extraction for TLS data methods. A 3D straight line segment extraction method is proposed based on spherical projection for single station terrestrial laser point clouds. Firstly, horizontal and vertical angles of each laser point are calculated by means of spherical coordinates, intensity panoramic image according to the two angles is generated. Secondly, edges which include straight line features are detected from intensity panoramic image by using of edge detection algorithm. Thirdly, great circles are detected from edges of panoramic image using spherical Hough transform. According to the axiom that a straight line segment in 3D space is a spherical great circle after spherical projection, detecting great circles from spherical projected data sets is essentially detecting straight line segments from 3D data sets without spherical projection. Finally, a robust 3D straight line fitting method is employed to fitting the straight lines and calculating parameters of the straight line segments. Experiments using different data sets and comparison with other methods show the accuracy and applicability of the proposed method.

Starting in 1958, Harry Harlow published numerous research papers analyzing the emotional and social development of rhesus monkeys. This essay examines the presentation of Harlow's work in introductory psychology textbooks from 1958 to 1975, focusing on whether the textbooks erased the process of research, presented results without hedging, and provided a uniform account of Harlow's work and results. It argues that many textbooks were not passive vehicles of knowledge transmission; instead, they played a role similar to articles of meta-analysis and literature reviews.

Changing Text: A Social Semiotic Analysis of Textbooks

Directory of Open Access Journals (Sweden)

Jeff Bezemer

2010-12-01

Full Text Available In this paper we provide a multimodal account of historical changes in secondary school textbooks in England and their social significance. Adopting a social semiotic approach to text and text making we review learning resources across core subjects of the English national curriculum, English, Science and Mathematics. Comparing textbooks from the 1930s, 1980s and 2000s, we show that a all modes operating in textbooks -typography, image, writing and layout- contribute to meaning and potential for learning b that the use of these modes has changed between 1930 and now, in ways significant for social relations between and across makers and users of textbooks. Designers and readers / learners now take responsibility for coherence, which was previously the exclusive domain of authors. Where previously reading paths were fixed by makers it may now be left to learners to establish these according to their interests. For users of textbooks the changes in design demand new forms of ‘literacy’; a fluency not only in ‘reading’ writing, image, typography and layout jointly, but in the overall design of learning environments. We place these changes against the backdrop of wider social changes and features of the contemporary media landscape, recognizing a shift from stability, canonicity and vertical power structures to ‘horizontal’, more open, participatory relations in the production of knowledge.

Low Horizontal Beta Function In Long Straights Of The NSLS-II Lattice

International Nuclear Information System (INIS)

Fanglei, L.; Bengtsson, J.; Guo, W.; Krinsky, S.; Li, Y.; Yang, L.

2011-01-01

The NSLS-II storage ring lattice is comprised of 30 DBA cells arranged in 15 superperiods. There are 15 long straight sections (9.3m) for injection, RF and insertion devices and 15 short straights (6.6m) for insertion devices. In the baseline lattice, the short straights have small horizontal and vertical beta functions but the long straights have large horizontal beta function optimized for injection. In this paper, we explore the possibility of maintaining three long straights with large horizontal beta function while providing the other 12 long straights with smaller horizontal beta function to optimize the brightness of insertion devices. Our study considers the possible linear lattice solutions as well as characterizing the nonlinear dynamics. Results are reported on optimization of dynamic aperture required for good injection efficiency and adequate Touschek lifetime. This paper discusses dynamic aperture optimization for the NSLS-II lattice with alternate high and low horizontal beta function in the long straights, which is proposed for the optimization of the brightness of insertion devices. The linear optics is optimized to meet the requirements of lattice function and source properties. Nonlinear optimization for a lattice with working point at (37.18, 16.2) is performed. Considering the realistic magnets errors and physical apertures, we calculate the frequency maps and plot the tune footprint. The results show that the lattice with high-low beta function has adequate dynamic aperture for good injection efficiency and sufficient Touschek lifetime.

Du, Quanye; Xu, Biao; Cao, Hui

2009-10-01

This paper presents a registration method which based on straight lines primitive. Firstly, 2D straight lines are extracted from aerial images using Canny operator and straight line fitting. In the similar way, 3D straight lines are extracted from LiDAR range images which derive from laser scanning point cloud. Secondly, 3D straight lines are projected to aerial images using collinearity equations and Position and Orientation System (POS) data. Then the corresponding lines are determined by straight line error. At last, each image's new exterior orientation elements are calculated by generalized point (straight line) photogrammetry.

Shipman, Harry L.; Finkelstein, N.; McCray, D.; Mac Low, M.; Zollman, D.

2006-12-01

In May 2006, a group of scientists, publishers, technology gurus, National Science Foundation officers, and other interested parties met for a few days to think collectively about the future of the textbook. We met because: -The Web and search engines like Google change the relationship between students and information. If the textbook no longer needs to be encyclopedic, then what is its role? --Knowing information is not enough. Our students, whether they follow academic or other careers, will need to know how to get information, evaluate it, and use it to solve real world problems. How can a textbook help students in these environments? --The static, comprehensive narrative of a textbook does not always lend itself well to inquiry learning, which is strongly encouraged by science education research and by national science k-12 education standards. How can textbooks support active, student-centered learning and support new faculty as they adopt it? The workshop generated partial and uncertain answers to these questions, providing some ideas for the future, though not a complete roadmap. A metaphor that generated considerable support among the group was the idea of a textbook as a compact travel guide, like the Lonely Planet guides. It should be adaptable, and thus web-based, but it might still exist in paper form. The participants discussed barriers on the path ahead. How will peer review, which many workshop participants value, be incorporated? What incentives could motivate textbook authors and publishers to produce truly innovative products? How will new technologies such as computer simulations & animations, electronic readers, and widely accessible databases reshape the role of the textbook in education? Many workshop participants including this paper’s authors acknowledge support from the NSF Distinguished Teaching Scholars Program and the NSF CAREER awards program.

Body image in gay and straight men: a qualitative study.

Science.gov (United States)

Morgan, John F; Arcelus, Jon

2009-11-01

Recent research has emphasized vulnerability to eating disorders in gay men, with calls for research on causality, cultural factors and focus on a younger age cohort. This study aimed to examine body image and related eating behaviours in younger gay and straight men. Qualitative study using a sample of gay and straight male university students, applying audiotaped and transcribed depth interview subjected to interpretative phenomenological analysis. Fifteen young men (18-24) with a spectrum of sexual orientation (gay, straight and bisexual) agreed to participate. Five dominant categories emerged: body image ideal, external influences, perception of body image, dieting, mechanisms for modification (diet, exercise, cosmetics) and sexual orientation. Health and aesthetic ideals appear less divorced for young men than women, offering some degree of protection from eating disorders. Nonetheless there is widespread body dissatisfaction. Media and social influences are powerful, particularly for single gay men, but the study suggests fewer differences than similarities between gay and straight men.

Perspectives on Violence Against Women: A Study of United States Nursing Textbooks.

Science.gov (United States)

Price-Glynn, Kim; Missari, Stacy

2017-03-01

This study examines conceptualizations of violence against women in U.S. nursing textbooks published from 1995 to 2005. Framing this pivotal decade, the federal Violence Against Women Act (VAWA) was passed and renewed. The American Nurses Association, the National League for Nursing, and the American Association of Colleges of Nursing also recognized violence against women as a health care priority. Sampling 107 generalist nursing textbooks from 1995 to 2005, the current study analyzes textbook terminologies, arguments, and protocols. Textbooks including violence were empirically tested for their application of gender neutral, symmetrical, and asymmetrical theoretical frameworks. Over 40% of generalist textbooks did not mention violence against women. Despite the VAWA in 1994 and broad recognition across national nursing organizations, textbooks did not change with regard to their treatment of violence over the next decade. The frameworks that nursing textbooks use may foster challenges for nurses in recognizing, supporting, and assisting women who are victims/survivors of violence. [J Nurs Educ. 2017;56(3):164-169.].

Chen Benyong; Zhang Enzheng; Yan Liping; Li Chaorong; Tang Wuhua; Feng Qibo

2009-01-01

Not only the magnitude but also the position of straightness errors are of concern to users. However, current laser interferometers used for measuring straightness seldom give the relative position of the straightness error. To solve this problem, a laser interferometer for measuring straightness and its position based on heterodyne interferometry is proposed. The optical configuration of the interferometer is designed and the measurement principle is analyzed theoretically. Two experiments were carried out. The first experiment verifies the validity and repeatability of the interferometer by measuring a linear stage. Also, the second one for measuring a flexure-hinge stage demonstrates that the interferometer is capable of nanometer measurement accuracy. These results show that this interferometer has advantages of simultaneously measuring straightness error and the relative position with high precision, and a compact structure.

Retrotext- E 1.0: The Beginnings of Computer-based ELT Textbook Evaluation

Directory of Open Access Journals (Sweden)

Jayakaran Mukundan

2010-07-01

Full Text Available There are two main reasons why textbooks are evaluated; the first which is associated to the task of textbook selection (predictive evaluation and the second to the need to evaluate it while in use (retrospective evaluation so that teachers can implement adaptation procedures later. Predictive evaluation is almost nonexistent in most developing countries as textbooks are usually provided free or through a textbook loan scheme. There is however hope for getting teachers involved in while-use/post use or retrospective evaluation of textbooks as they no only help teachers with adaptation but help teachers in their overall professional development. Since textbooks are an essential part of the teacher’s professional  life any form of out-of-class work that involves the teacher’s own knowledge building can become an integral part of the teacher’s professional development.

Plant physiology at the institute for philosophy in Brno in Mendel’s teacher F. Diebl textbook from 1835

Directory of Open Access Journals (Sweden)

Jiří Šebánek

2012-01-01

Full Text Available Gregor Mendel attended lectures of F. Diebl, professor of natural history and agricultural science at the Institute of Philosophy in Brno. Diebl published his lectures in a textbook “Abhandlungen über die allgemeine und besondere Naturgeschichte, Brünn 1835.” From the textbook the level of scientific knowledge in plant biology is obvious, with which the later founder of a new field of biology – genetics got acquainted. Diebl considered germination to be a specific method of fermentation transforming seed starch into a sugary matter which nourishes the germinating plant. In the physiology of nutrition he distinguished nutrition from the soil via roots from nutrition from the air via leaves. The former is based primarily on the humus theory of A. Thaer (1809 because not until 5 years after the publication of Diebl’s textbook J. Liebig initiated the mineral theory. Diebl’s presentation of photosynthesis was based on information available at that time about the release of oxygen by green plants under conditions of light and the uptake of CO2, but he had no knowledge about the passage of CO2 into the leaves through stomata. Remarkable is Diebl’s discovery that respiration increases during flowering. Electricity is considered to be a force significantly supporting the life processes of plants. Diebl also noticed the difference between diurnal and night evaporation of water from the leaves. In his textbook growth is connected with nutrition only, as it was the entire 19th century. Stem thickening from the cambium is described very simply. Bud and root regeneration is given the term reproduction which today is commonly used in relation to sexual reproduction. Diebl considered nyctinastic movements (bending or unbending of the leaves and closing of the flowers at night to be “sleep”. He described fertilisation in a primitive way, because it was not until 1848 that the first exact description came out.

Ali Roohani

2013-07-01

Full Text Available Abstract: Textbooks can affect learners’ attitudes, viewpoints, and their choice of language in second/foreign language (L2 communication. The various ways in which the people are displayed in communication may affect students’ viewpoints. This study was an attempt to examine several potential areas of gender-bias in the representation of women and men in the pre-university English textbook, an English language teaching (ELT textbook with two volumes taught in the high schools of Iran. To evaluate this textbook, content analysis was done in terms of gender-bias, gender-neutral, male-generics, and the firstness in the reading texts, instructions, exercises and illustrations. The frequency and percentages of names, nouns, pronouns and pictures attributed to each gender (i.e., males and females were obtained and chi-square tests were carried out. In general, names, nouns and pictures pertinent to males outnumbered those attributed to females. Besides, there was a statistically significant difference between males and females in the two volumes of the pre-university textbook in terms of the above features. Also, male-oriented terms came first more frequently. However, there was not a statistically significant difference between male and female pronouns between the two volumes, though the percentage of male pronouns was higher. Moreover, the textbook included many gender-neutral nouns and pronouns not having any gender orientations. Findings indicated that the Iranian pre-university English textbook was somehow male-oriented and gender-biased as regards names, nouns, firstness and pictures associated with them though great efforts were made to avoid specific gender orientations.

Full Text Available This study aims to examine the treatment of linguistic variation in Brazilian Portuguese textbooks for High School and prompts a debate about concepts like right and wrong, language variation, language change and language prejudice. In this sense, it considers whether the textbook discusses the linguistic variation, understanding it as a result of a variety of sociocultural factors of a linguistic community. Our corpus consists of a collection of Portuguese Language for High School, prepared by Carlos Alberto Faraco, approved by the National Textbook Program (PNLD 2015. The research is part of the dialogue between Sociolinguistics and mother tongue teaching, more specifically, in theoretical and methodological studies of Bortoni-Ricardo (2004, Faraco (2004, Alkmim (2005, Labov (2008, among others, in addition to the National Curriculum Parameters of High School Portuguese Language – PCN (BRASIL, 2000. The methodology is based on descriptive, bibliographical and documentary research and a qualitative approach. The results show, that the current development, in that collection highlights a concern to incorporate linguistic studies in the heterogeneity and linguistic diversity from sociolinguistic perspective.

Additional Quadrupoles At Center Of Long Straights In The NSLS-II Lattice

International Nuclear Information System (INIS)

Lin, F.; Bengtsson, J.; Guo, W.; Krinsky, S.; Li, Y.; Yang, L.

2011-01-01

The NSLS-II storage ring lattice is comprised of 30 DBA cells arranged in 15 superperiods. There are 15 long straight sections (9.3m) for injection, RF and insertion devices and 15 shorter straights (6.6m) for insertion devices. In the baseline lattice, the short straights have small horizontal and vertical beta functions but the long straights have large horizontal beta function optimized for injection. In this paper, we explore the possibility of installing additional quadrupoles at the center of selected long straight sections in order to provide two low-beta source locations for undulators in the same straight. The required modification to the linear lattice is discussed as well as the preservation of adequate dynamic aperture required for good injection efficiency and adequate Touschek lifetime. This paper discusses the possibility of producing two low-beta source locations for optimum brightness of undulators in the long straights of NSLS-II lattice by installing additional quadrupoles at the center. The linear optics is optimized to satisfy the requirements of lattice function and properties. Nonlinear optimization for a lattice with working point at (37.16, 17.22) is performed. Considering the magnets misalignment errors and physical apertures, we calculate the frequency maps and plot the tune footprint. The results show that the modified high-low beta function lattice can achieve a modest dynamic aperture in this preliminary study. Further work will continue to expand the dynamic aperture to meet the requirement of good injection efficiency and sufficient Touschek lifetime.

Propagation of ovalization along straight pipes and elbows

International Nuclear Information System (INIS)

Millard, A.; Roche, R.L.

1981-01-01

The aim of this paper is to present analytical solutions for the propagation of evalization and the variation of the flexibility factor along pipe bends terminated by straight pipes or flanges, under in-plane bending, assuming an elastic material behaviour. The influence of the various strains in analysed in the simple case of a straight pipe, subjected to an elliptical cross-section shape deformation at one end. The results enlighten the very important part played by the distorsion in the propagation. They have been compared with finite elements solutions and with simple experiments. The solution is developed for an elbow terminated by a straight pipe or a flange, following the Von Karman's approach: local displacements are expanded in Fourier series, the coefficients of which vary along the curvilinear abscissa, like the rotation of the cross-section as a whole; the differential equations as well as the boundary conditions are found by minimization of the total potential energy of the assembly. The solutions are compared to existing and experimental results. (orig./HP)

Hola, O.; Holy, K.

2005-01-01

In our contribution we want to outline our plan of actions to be carried out for the creation of the first multimedia internet textbook in Slovakia in the field of ionizing radiation and radiation protection. In particular we want to describe first steps that have been performed at its realisation. This textbook would be applicable to the full-time study as well as to distance learning at traditional universities and technical universities. It will also be usable for various forms of in-service training by e-learning. Our objective is to create a modem internet textbook in radiation protection, of which production will be co- ordinated with other European Union countries. The output of our project -the multimedia textbook -will be available to all students at our university's servers and other users will have CDs at their disposal. We propose the use of this multimedia didactic means also in various forms of the distance e-learning. The main motivation for the implementation of distance courses is the necessity to update knowledge, skills and qualification in our contemporary rapidly developing world. The distance e-learning form of education can solve also the problem with the acquisition of the professional qualifications for the work with ionizing radiation. This is the reason for usage of the mentioned textbook not only as the fundamental and unified textbook for the students of universities, but also as the study material for the civil servants responsible for radiation protection, for in-service workers and providers of the professional training.

History of science content analysis of Chinese science textbooks from the perspective of acculturation

Science.gov (United States)

Ma, Yongjun; Wan, Yanlan

2017-08-01

Based on previous international studies, a content analysis scheme has been designed and used from the perspective of culture to study the history of science (HOS) in science textbooks. Nineteen sets of Chinese science textbooks have been analyzed. It has been found that there are noticeable changes in the quantity, content, layout, presentation, and writing intention of the HOS sections in textbooks from different time periods. What's more, the textbooks aim at presenting the scientific culture and aim to help students understand it better. However, the cultural associations of the HOS in textbooks is insufficient and significant differences exist among textbooks of different subjects. In order to explore the reasons why the presentation of HOS in various subjects is different, we made a specific comparison of curriculum standards of two subjects with great differences and interviewed the editors-in-chief of two textbooks. Results show that one of the most important reasons for the different writings of the HOS in textbooks is that different subject curriculum standards attach greater importance to the HOS. In addition, the attention to the HOS by editors-in-chief, the tradition of studying the HOS within the history of the discipline, and the reference textbooks in compiling textbooks are all important influence factors. Some suggestions for future textbooks compilation are given at the end.

2017-09-01

Full Text Available Textbooks have been considered to play a key role in the processes of education by researchers and educators, and the need to explore the language of textbooks has become increasingly recognized. However, although textbooks are an important learning tool, textbook language and composition have not been widely explored especially from textual perspectives. The purpose of the present study is to investigate text complexity progression in the reading texts of English textbooks published for senior high school students in Indonesia. The nature and rate of that progression are addressed within the framework of Systemic Functional Linguistics. Being largely qualitative, this study examines three consecutive textbooks issued by the Ministry of Education, which are available online for classroom use. Data were collected and sampled from the reading texts found in the textbooks and were analyzed with regard to lexical density, lexical variation and grammatical intricacy in order to find the complexity of the texts. The results of the analyses show that regardless of the inconsistent progression of text complexity within each textbook, there is a consistent pattern of text complexity progression across grade levels. In other words, the lexical density, lexical variation and grammatical intricacy across the textbooks were found to have consistent progression from one grade level to another of which the direction is positive. It could be concluded that in general the language used in the texts becomes increasingly sophisticated, especially at lexical level, in accordance with grade level progression to cater for students’ intellectual development.

2017-03-21

The saphenous vein is commonly used as a vascular graft in peripheral artery surgery but rarely used for vascular access. The literature on straight configuration saphenous vein transposition to the popliteal artery is scarce. Here we present two cases of straight configuration saphenous vein transposition to the popliteal artery for vascular access, the surgical technique and respective follow-up. Two young men, aged 29 and 36 years, were chosen for lower-limb vascular access for hemodialysis. The first patient was paraplegic since birth. He used his arms to move so upper extremity vascular access was avoided. The second patient presented with an infected upper extremity arteriovenous graft (AVG) and after multiple closed AVFs he had no more available arm veins. Both patients received autologous lower extremity straight configuration saphenous vein transpositions to the popliteal artery under spinal anesthesia in May and October 2012, respectively. Cannulation of the fistula was allowed after one month. There were no early complications. Slight swelling on the leg appeared in one of the patients. Both fistulas were still functional after 36 and 32 months, respectively. The straight configuration saphenous vein transposition to popliteal artery is simple to perform, offers a long and straight segment for cannulation and may be a suitable autologous vascular access in selected patients.

2017-05-01

Full Text Available Standards-Based Approach to textbook evaluation has been blooming in recent decades. Nevertheless, this practice has received very little attention in Morocco.  The present study aims to bridge a gap in the literature of the Moroccan context by investigating the extent to which three locally designed ELT textbooks conform to the theoretical principles of the Standards-Based Approach which defines the teaching of English as a foreign language in the country (Ministry of National Education, 2007. Its objective is to examine whether and how these textbooks present contents that enable learners to meet the content standards included in the goal areas of Communications, Cultures, Connections and Comparisons. The study is informed by the theoretical framework of the Standards-Based Approach. It adopts a mixed-methods design that uses content analysis as a mixed data analysis method combining both quantitative and qualitative techniques. The findings reveal a number of shortcomings relevant to the representation of the content standards as several standards are not sufficiently addressed in the activities included in these textbooks. Eventually, some suggestions are addressed to policy makers, textbook designers and teachers to overcome the identified problems in current and future textbooks. The study is expected to sensitize ELT practitioners about the viability of using textbook evaluation in boosting both the quality of ELT textbooks and the quality of the teaching learning outcomes.

Full Text Available In other to facilitate the automation of camera calibration process, a mathematical model using straight lines was developed, which is based on the equivalent planes mathematical model. Parameter estimation of the developed model is achieved by the Least Squares Method with Conditions and Observations. The same method of adjustment was used to implement camera calibration with bundles, which is based on points. Experiments using simulated and real data have shown that the developed model based on straight lines gives results comparable to the conventional method with points. Details concerning the mathematical development of the model and experiments with simulated and real data will be presented and the results with both methods of camera calibration, with straight lines and with points, will be compared.

A gender analysis of secondary school physics textbooks and laboratory manuals

Science.gov (United States)

Kostas, Nancy Ann

Secondary school physics textbooks and laboratory manuals were evaluated for gender balance. The textbooks and manuals evaluated were all current editions available at the time of the study with copyrights of 1988 to 1992. Illustrations, drawings and photographs were judged gender balanced based on the number of men and women, boys and girls shown in both active and passive roles. Illustrations, drawings and photographs were also evaluated by the number of male and female scientists identified by name. The curricular content of the textbooks was analyzed for gender balance by three criteria: the number of named male and female scientists whose accomplishments were described in the text; the number of careers assigned to men and women; and the number of verbal analogies assigned to girls interests, boys interests or neutral interests. The laboratory activities in the manuals were categorized as demonstrations, experiments and observations. Three of each of these types of activities from each manual were analyzed for skills and motivating factors important to girls as identified by Potter and Rosser (1992). Data were analyzed by use of descriptive statistics of frequencies, means and chi-square goodness of fit. The.05 level of significance was applied to all analyses based upon an expected frequency of 50 - 50 percentage of men and women and a 4.5 percent for women scientists to 95.5 percent for men scientists. The findings were as follows. None of the textbooks had a balance of men/women, boys/girls in the illustrations, drawings and photographs. The Hewitt (Scott-Foresman, 1989) textbook was the only textbook with no significant difference. Using the expected frequency for male and female scientists, two textbooks were gender balanced for illustrations, drawings and photographs while all textbooks were gender balanced for described accomplishments of scientists. The Hewitt (Scott Foresman, 1989) textbook had the only gender balanced representation of careers

Cherry Picking: Virginity Loss Definitions Among Gay and Straight Cisgender Men.

Science.gov (United States)

Huang, Howard

2017-08-03

Virginity loss is a vital milestone in the development of one's sexual identity. Unfortunately, there is very little literature available studying virginity loss definitions among the wider straight population, and even less examining virginity loss among LGBTQ+ populations. The present study recruited 251 (45.4%) cisgender straight men and 114 (54.6%) cisgender gay men. An online, anonymous survey was administered to explore whether they considered various male-on-male (M-M) and male-on-female (M-F) sexual behaviors as constitutive of virginity loss. Results indicate that more gay men than straight considered M-M receptive anal intercourse (i.e., bottoming) and M-F penetrative anal intercourse to be constitutive of virginity loss. Results also indicate that both gay and straight men almost unanimously endorsed M-F penovaginal sex to be constitutive of virginity loss. This study is a first-step toward gaining a better understanding of LGBTQ+ virginity loss conceptualizations. Future research is strongly encouraged.

The ever increasing fossil fuel usage and cost, environmental concern has forced the world to look for alternatives. Straight vegetable oils in compression ignition engine are a ready solution available, however, with certain limitations and with some advantages as reported by many researchers. A comprehensive and critical review is presented specifically pertaining to straight vegetable oils usage in diesel engine. A detailed record of historical events described. Research carried out specifically under Indian conditions and international research work on the usage of straight vegetable oils in the diesel engine is separately reviewed. Many researchers have reported that straight vegetable oils in small percentage blends with diesel when used lower capacity diesel engines have shown great promise with regards to the thermal performance as well exhaust emissions. This has been explained in detail. Finally based on the review of international as well as Indian research a SWOT analysis is carried out. The review concludes that there is still scope for research in this area. (author)

Full Text Available The present study aimed at probing into the use of grammatical and lexical cohesive subdevices in Iranian high school EFL textbooks. To this end, the reading sections of three high school EFL textbooks and one pre-university EFL textbook were analyzed in terms of the distribution of grammatical and lexical cohesive subdevices. The results of One-way ANOVA illustrated that: athere are no significant differences among the frequencies of grammatical cohesive subdevices across grade 1 high school EFL textbook and the pre-university EFL textbook, bthere are significant differences among the frequencies of grammatical cohesive subdevices across grades 2 and 3 high school EFL textbooks. Moreover, the results of Chi-Square test showed that the significant values of all of the lexical cohesive subdevices were higher than .05 across each of the Iranian EFL high school textbooks. These findings can be beneficial for textbook writers, materials developers and EFL teachers.

Curved-straight neutron guide system with uniform spatial intensity distribution

International Nuclear Information System (INIS)

Mildner, D.F.R.; Cook, J.C.

2008-01-01

The spatial intensity distribution of neutrons emerging from a curved guide is asymmetric, and straight guide sections are sometimes appended to curved guides to make the intensity distribution more nearly uniform. For idealized uniform illumination and in the perfect reflectivity approximation, the spatial-angular acceptance at the exit of the combination can be made exactly uniform for a range of long wavelengths by using a sufficiently long straight section, together with a curved guide whose outer wall coating has a critical angle slightly greater than those of the other guide walls. We refer to this as a 'phase space tailoring guide' where the coatings on the inner wall and straight section are used to define the required divergence at the end of the guide. Increasing the critical angle of the outer wall of the curved section reduces the characteristic wavelength of the curved guide as well as the wavelength at which ideal uniformity can be obtained. The outer wall coating need only be of sufficiently high critical angle to fill the transmittable phase space area of the straight guide uniformly to adequately short wavelength

A Praxeological Study of Proportionality in Mathematics Lower Secondary Textbooks

Brunet, Darlene P; Bates, Michael L; Gallo, John R; Strother, Elizabeth A

2011-05-01

Since 2005, the Louisiana State University Health Sciences Center School of Dentistry has required the VitalSource Technologies, Inc. Bookshelf as the textbook program for all dental students. In a 2008 survey, four classes of dental students expressed dissatisfaction with most features of the bookshelf. With the expectation that incoming students would be more accustomed and amenable to digital textbooks and to further determine student attitudes toward electronic textbooks, we developed two surveys for first-year dental students in the class of 2013. The sixty-five first-year students received a survey (S1) one week before they were introduced to the e-textbook program. Questions centered on their undergraduate experience with e-books and their expectations of studying with an electronic textbook collection. In the second survey (S2), sent nine months later, the questions focused on students' opinion of the VitalSource Bookshelf. Forty-five students (69.2 percent) completed the S1 survey. Of those, thirty-six (80 percent) responded that they never used e-textbooks in college. Of the nine students who responded that they used e-books, only two liked them without reservations. The response rate to S2 increased to fifty students (77 percent). After using VitalSource for nine months, thirty-three students (66 percent) indicated a preference for reading print textbooks, compared to forty-seven students (57.3 percent) of the four classes surveyed in 2008. Although we expected incoming dental students to have had previous experience with e-textbooks, only nine students had used e-books in college courses. Few students indicated preference for e-textbooks, and over half of the group was undecided. After experience with VitalSource for first-year courses, students indicated that they like VitalSource for the ability to search for specific topics across the entire collection of dental books, but not for reading large amounts of text.

Book Review: Khine Swe, M. (Ed., Critical Analysis of Science Textbooks: Evaluating instructional effectiveness

Directory of Open Access Journals (Sweden)

Miha Slapničar

2014-03-01

Full Text Available Science educators agree that textbooks play a crucial role in teaching and learning processes (Clement, 2008; Koppal & Caldwell, 2004; consequently, numerous research studies have been conducted in the analysis of science textbooks. In 1941, Graham noted that ‘The textbook is an old instrument in learning and teaching processes’ and traced the origin of the textbook back to the classical Greek era. With the invention of the printing press, textbooks became omnipresent in every school. Since textbooks are being used as a major source of information in teaching a particular subject, the quality and accuracy of the content is crucial for their educational effectiveness. Critical Analysis of Science Textbooks: Evaluating instructional effectiveness includes contributions by authors from various backgrounds, theorists and practitioners. In analysing science textbooks, researchers look into the balance between theoretical and practical knowledge, the portrayal of minorities, women and gender fairness, the treatment of socio-scientific and controversial issues, and the depiction of graphical information, vocabulary load, comprehensibility and readability at the intended level, the representation of indigenous knowledge, the role of textbook questions, and cultural and religious sensibility

Designing a Tool for History Textbook Analysis

Directory of Open Access Journals (Sweden)

Katalin Eszter Morgan

2012-11-01

Full Text Available This article describes the process by which a five-dimensional tool for history textbook analysis was conceptualized and developed in three stages. The first stage consisted of a grounded theory approach to code the content of the sampled chapters of the books inductively. After that the findings from this coding process were combined with principles of text analysis as derived from the literature, specifically focusing on the notion of semiotic mediation as theorized by Lev VYGOTSKY. We explain how we then entered the third stage of the development of the tool, comprising five dimensions. Towards the end of the article we show how the tool could be adapted to serve other disciplines as well. The argument we forward in the article is for systematic and well theorized tools with which to investigate textbooks as semiotic mediators in education. By implication, textbook authors can also use these as guidelines. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs130170

EFL Published Materials: An Evaluation of English Textbooks for Junior High School in Indonesia

Directory of Open Access Journals (Sweden)

Rizaldy Hanifa

2018-04-01

Full Text Available The use of EFL published materials like textbooks are becoming more widespread as they can bring easiness in the classroom by providing teachers with guidelines comprised of syllabus, methodologies, as well as materials for teaching and learning. However, choosing a suitable textbook for their teaching situation is deemed to be one of the most challenging tasks that EFL teachers often face. To get a good picture of the suitability of a textbook, a careful investigation needs to be undertaken. This study focused on the analysis and evaluation of two different English textbooks addressed to junior high schools grade VII in Indonesia, KTSP and curriculum 2013 textbook. Harmer’s (2007 framework was employed to figure out the strengths and weaknesses of each textbook. The analysis revealed that both textbooks are quite satisfactory as they are very affordable, contain interesting layout, attractive designs, and clear instructions, correspond to current ELT methodology, cover all language skills, and comprise a wide range of topics which are familiar and culturally appropriate for learners. Nonetheless, the KTSP textbook does not have add-ons and extra materials; meanwhile, curriculum 2013 textbook is weak in providing authentic listening materials. Therefore, although the teachers manage to use the textbooks as their core materials, they are supposed to make adjustment and supplement them with other materials according to their learners’ needs and their teaching context.

Research and pedagogy a history of quantum physics through its textbooks

CERN Document Server

Navarro, Jaume

2013-01-01

Historians of quantum physics and early quantum mechanics have seldom paid attention to the ways the new theory was integrated in physics textbooks, perhaps taking for granted that novelties in science can only be taught once they are fully understood and generally accepted. The essays in this volume challenge this view by studying some of the early books and textbooks in which quantum theory was first introduced. By so doing, the authors show the many ways books and textbooks embody pedagogical and research practices in certain local environments (geographical, disciplinary, in terms of expertise, etc.), as well as the circular feedback between research and pedagogy. Textbooks can become the subject of a history of early quantum physics since the very process of writing a textbook, (i.e., of trying to organise a new doctrine to the newcomer in an accessible way), together with its life as an object that is issued, used, changed, and abandoned, incorporates many of the tensions between research and pedagogy....

The importance of natural-disaster education for social preparedness is presented. Increasing damage caused by natural disasters around the globe draws attention to the fact that even developed societies must adapt to natural processes. Natural-disaster education is a component part of any education strategy for a sustainably oriented society. The purpose of this article is to present the role of formal education in natural disasters in Europe. To ensure a uniform overview, the study used secondary-school geography textbooks from the collection at the Georg Eckert Institute for International Textbook Research in Braunschweig, Germany. Altogether, nearly 190 textbooks from 35 European countries were examined. The greatest focus on natural disasters can be found in textbooks published in western Europe (3.8% of pages describing natural disasters), and the smallest in those published in eastern Europe (0.7%). A share of textbook pages exceeding three percent describing natural disasters can also be found in northern Europe (3.6%) and southeast Europe, including Turkey (3.4%). The shares in central and southern Europe exceed two percent (i.e., 2.8% and 2.3%, respectively). The types and specific examples of natural disasters most commonly covered in textbooks as well as the type of natural disasters presented in textbooks according to the number of casualties and the damage caused were analyzed. The results show that the majority of European (secondary-school) education systems are poorly developed in terms of natural-disaster education. If education is perceived as part of natural-disaster management and governance, greater attention should clearly be dedicated to this activity. In addition to formal education, informal education also raises a series of questions connected with the importance of this type of education. Special attention was drawn to the importance of knowledge that locals have about their region because this aspect of education is important in both

Textbook in global society: a few steps towards the methodology of comparative research

Full Text Available The paper analyzes differences in primary school textbook publishing models in European Union, United States and Slovenia. Regardless the fact that there exist important differences among these models, in the majority of states there is competition among textbooks for the same subject. Nevertheless, the textbook is not a marketable good as any other: it is also a carrier of social and cultural values. Even more, in most cases, the decision which textbook to buy is not taken by the parent who pays for the textbook, but by the teacher who has no financial obligations in the whole process. As a result, textbook market is unperfect, and the majority of states regulates it more thoroughly than markets for other goods. Adoption processes are one of the most important keys for understanding the nature of such regulation. They are closely related to the nature of educational legislation: in the states with final-oriented legislation,the adoption processes are more common than in the states with process-oriented legislation. In Slovenia, the state has started to withdraw from textbook publishing in early eighties. Nevertheless, the state still adopts and evaluates textbook content,and is therefore more process than final oriented.

Full Text Available Established during the Japanese protectorate period, the censorship system lasted throughout the colonial period as well. Therefore it is necessary to examine such censorship system as part of Japan’s colonization policy and shed light on the historical and current significance of the censorship system as well as its effects. Recently, copies of textbook provided to the Ministry of Education (Hakbu for inspection in the protectorate period were newly discovered. Materials that have been inspected by the Japanese Residency-General of Korea—inspection copies of textbooks from the Young Korean Academy (Heungsadan—were included in the “Collection of new materials related to Yu Kilchun”. Using these newly discovered copies of textbooks that had been subject to inspection, this study is the first in a series of research that attempted to examine actual cases of textbook inspection and censorship during the protectorate period and shed light on the historical significance of such activities. This study therefore review legislations on inspection and censorship in this period and studied the early stages in the establishment process of a censorship system in modern Korea. Secondly, this study attempted to provide a bibliographical analysis of the inspection copies of textbooks from the protectorate period, as these are new documents that had never been analyzed or used in research.

The teaching of evolution in Portugal in the early 20th century through the programs and textbooks of Zoology

Directory of Open Access Journals (Sweden)

Bento CAVADAS

2011-11-01

Full Text Available The teaching of evolution in the Portuguese secondary schools is not yet fully understood. This research aimed to contribute to this clarification, in the framework of the history of the curriculum and the biology subject, by showing the expressions of the evolutionism teaching in the first three decades of the twentieth century. To this end we analyzed the programs of Zoology of 1905 and 1919, as well as two textbooks, entitled «Lições de Zoologia» and written by Bernardo Aires in accordance with these programs. This analysis showed that the study of evolution, eliminated from the program in 1905, was again recognized in the program in 1919. In textbooks, the exposure of evolution focused on the subject of evolution, in the grounds of competition and natural selection, adaptation, the biogenetic law and the essential differences between Lamarckism and Darwinism. The comparative study of these textbooks showed that the text which addresses the evolution is essentially Darwinian. However, neoLamarckians sections have been identified that show the influence of the «eclipse of Darwinism» on the teaching of evolutionism.

Gender, health behavior, and intimate relationships: lesbian, gay, and straight contexts.

Science.gov (United States)

Reczek, Corinne; Umberson, Debra

2012-06-01

Many studies focus on health behavior within the context of intimate ties. However, this literature is limited by reliance on gender socialization theory and a focus on straight (i.e., heterosexual) marriage. We extend this work with an analysis of relationship dynamics around health behavior in 20 long-term straight marriages as well as 15 gay and 15 lesbian long-term cohabiting partnerships in the United States (N = 100 individual in-depth interviews). We develop the concept of "health behavior work" to align activities done to promote health behavior with theories on unpaid work in the home. Respondents in all couple types describe specialized health behavior work, wherein one partner works to shape the other partner's health behavior. In straight couples, women perform the bulk of specialized health behavior work. Most gay and lesbian respondents-but few straight respondents--also describe cooperative health behavior work, wherein partners mutually influence one another's health behaviors. Findings suggest that the gendered relational context of an intimate partnership shapes the dynamics of and explanations for health behavior work. Copyright © 2011 Elsevier Ltd. All rights reserved.

Seomun, Gyeongae; Lee, Jung-Ah; Kim, Eun-Young; Im, Meeyoung; Kim, Miran; Park, Sun-A; Lee, Youngjin

2013-10-01

This qualitative study used the grounded theory approach to analyze digital textbook-related health experiences of school-age children. In-depth interviews were held with 40 elementary school students who had used digital textbooks for at least a year. Data analysis revealed a total of 56 concepts, 20 subcategories, and 11 categories related to digital textbook health issues, the central phenomena being "health-related experiences." Students' health-related experiences were classified into "physical" and "psychological" symptoms. Adverse health effects related to digital textbook usage were addressed via both "student-led" and "instructor-led" coping strategies. Students' coping strategies were often inefficient, but instructor-led strategies seemed to prevent health problems. When health issues were well managed, students tended to accept digital textbooks as educational tools. Our findings suggest that students can form healthy computer habits if digital textbook usage is directed in a positive manner.

Genetic engineering: a matter that requires further refinement in Spanish secondary school textbooks

Science.gov (United States)

Martínez-Gracia, M. V.; Gil-Quýlez, M. J.

2003-09-01

Genetic engineering is now an integral part of many high school textbooks but little work has been done to assess whether it is being properly addressed. A checklist with 19 items was used to analyze how genetic engineering is presented in biology textbooks commonly used in Spanish high schools, including the content, its relationship with fundamental genetic principles, and how it aims to improve the genetic literacy of students. The results show that genetic engineering was normally introduced without a clear reference to the universal genetic code, protein expression or the genetic material shared by all species. In most cases it was poorly defined, without a clear explanation of all the relevant processes involved. Some procedures (such as vectors) were explained in detail without considering previous student knowledge or skills. Some books emphasized applications such as the human genome project without describing DNA sequencing. All books included possible repercussions, but in most cases only fashionable topics such as human cloning. There was an excess of information that was not always well founded and hence was unsuitable to provide a meaningful understanding of DNA technology required for citizens in the twenty-first century.

The role of business agreements in defining textbook affordability and digital materials: A document analysis

Full Text Available Adopting digital materials such as eTextbooks and e-coursepacks is a potential strategy to address textbook affordability in the United States. However, university business relationships with bookstore vendors implicitly structure which instructional resources are available and in what manner. In this study, a document analysis was conducted on the bookstore contracts for the universities included in the State University System of Florida. Namely, issues of textbook affordability, digital material terminology and seller exclusivity were investigated. It was found that textbook affordability was generally conceived in terms of print rental textbooks and buyback programs, and that eTextbooks were priced higher than print textbooks (25% to 30% markup. Implications and recommendations for change are shared. DOI: 10.18870/hlrc.v5i4.284

Direct laryngoscopy can be performed using curved or straight blades, and providers usually choose the blade they are most comfortable with. However, curved blades are anecdotally thought of as easier to use than straight blades. We seek to compare intubation success rates of paramedics using curved versus straight blades. Design: retrospective chart review. hospital-based suburban ALS service with 20,000 annual calls. prehospital patients with any direct laryngoscopy intubation attempt over almost 9years. First attempt and overall success rates were calculated for attempts with curved and straight blades. Differences between the groups were calculated. 2299 patients were intubated by direct laryngoscopy. 1865 had attempts with a curved blade, 367 had attempts with a straight blade, and 67 had attempts with both. Baseline characteristics were similar between groups. First attempt success was 86% with a curved blade and 73% with a straight blade: a difference of 13% (95% CI: 9-17). Overall success was 96% with a curved blade and 81% with a straight blade: a difference of 15% (95% CI: 12-18). There was an average of 1.11 intubation attempts per patient with a curved blade and 1.13 attempts per patient with a straight blade (2% difference, 95% CI: -3-7). Our study found a significant difference in intubation success rates between laryngoscope blade types. Curved blades had higher first attempt and overall success rates when compared to straight blades. Paramedics should consider selecting a curved blade as their tool of choice to potentially improve intubation success. Copyright © 2018 Elsevier Inc. All rights reserved.

Bhutani, Garima; Kalra, Sanjay

2015-01-01

The study is aimed to assess whether the information contained in standard pharmacology, endocrinology, and diabetology textbooks regarding timings of administration, frequency and dose of various insulins is adequate and also to see whether the information contained in these texts is concordant with product inserts. Four standard textbooks of pharmacology, two of diabetology and three of endocrinology were assessed for the published information regarding dose, timing, and frequency of insulin administration. The product inserts of commonly available insulins in India were also studied for the same. Various omissions and disparities could be seen in the coverage of insulins in standard textbooks. Posology information about premixed insulins and basal insulins have been omitted by the majority of the textbooks. Details about dose, frequency and timings of ultra-short acting insulins have also not been covered by all textbooks. Some discrepancies regarding prescribing information was also noted in product inserts, especially in case of newer insulins. Thus, this article stresses upon the need of a uniform source of information for providing adequate and standardized knowledge regarding timing, frequency, and dose of insulins.

The transmission of 1 and 3 MeV protons through a borosilicate straight glass capillary and a tapered glass capillary was investigated. The straight capillary had a diameter of ∼0.18 mm and a length of ∼14.4 mm, while the tapered capillary had an inlet diameter of ∼0.71 mm, an outlet diameter of ∼0.10 mm and a length of ∼28 mm. The results show that the 1 and 3 MeV protons traverse through both samples without energy loss, while the tapered capillary showed better transmission than the straight capillary. (paper)

Medical Subspecialty Textbooks in the 21st Century. Essential or Headed for Extinction?

Science.gov (United States)

Broaddus, V Courtney; Grippi, Michael A

2015-08-01

In recent years, the role of medical subspecialty textbooks as sources of information for students, trainees, and practicing clinicians has been challenged. Although the structure of textbooks continues to evolve from standard, printed versions to digital formats, including e-books and online texts, we maintain that the authoritative compilation of clinical and scientific material by experts in the field (i.e., a modern-day textbook) remains central to the education, training, and practice of subspecialists. Regardless of format, an effective medical subspecialty textbook is authoritative, comprehensive, and integrated in its coverage of the subject. Textbook content represents a unique synthesis of clinical and scientific material of real educational and clinical value. Incorporation of illustrations, including figures, tables, videos, and audios, bolsters the presentation and further solidifies the reader's understanding of the subject. The textbook, both printed and digital, reinforces the many widely available online resources and serves as a platform from which to evaluate other sources of information and to launch additional scientific and clinical inquiry.

Effect of iron catalyst thickness on vertically aligned carbon nanotube forest straightness for CNT-MEMS

International Nuclear Information System (INIS)

Moulton, Kellen; Jensen, Brian D; Morrill, Nicholas B; Konneker, Adam M; Vanfleet, Richard R; Allred, David D; Davis, Robert C

2012-01-01

This paper examines the effect of iron catalyst thickness on the straightness of growth of carbon nanotubes (CNTs) for microelectromechanical systems fabricated using the CNT-templated-microfabrication (CNT-M) process. SEM images of samples grown using various iron catalyst thicknesses show that both straight sidewalls and good edge definition are achieved using an iron thickness between 7 and 8 nm. Below this thickness, individual CNTs are well aligned, but the sidewalls of CNT forests formed into posts and long walls are not always straight. Above this thickness, the CNT forest sidewalls are relatively straight, but edge definition is poor, with significantly increased sidewall roughness. The proximity of a device or feature to other regions of iron catalyst also affects CNT growth. By using an iron catalyst thickness appropriate for straight growth, and by adding borders of iron around features or devices, a designer can greatly improve straightness of growth for CNT-MEMS.

Full Text Available The depiction of females and males in Mozambican Primary Mathematics textbooks for grades 6 and 7 were examined, and comparisons made with Victorian  (Australia textbooks for years 5 and 6. It was found that mathematics learning was portrayed as a  male domain in the Mozambican textbooks, reflecting what used to be the case with Australian texts of the 1970s, although there are some differences between the two countries that may be culturally based. The Victorian textbooks depicted mathematics learning as a domain for all children, and in the majority of categories examined, females and males were distributed fairly evenly. Compared to earlier reported findings, there was a general improvement in the portrayal of females in Victorian textbooks.

Finally, nuclear engineering textbooks with a Canadian flavour!

International Nuclear Information System (INIS)

Bonin, H.W.

2002-01-01

The need for nuclear engineering textbooks more appropriate to the Canadian nuclear industry context and the CANDU nuclear reactor program has long been felt not only among the universities offering nuclear engineering programs at the graduate level, but also within the Canadian nuclear industry itself. Coverage of the CANDU reactor system in the textbooks presently supporting teaching is limited to a brief description of the concept. Course instructors usually complement these textbooks with course notes written from their personal experience from past employment within the nuclear industry and from their research interests In the last ten years, the Canadian nuclear industry has been involved on an increasing basis with the issue of the technology transfer to foreign countries which have purchased CANDU reactors or have been in the process of purchasing one or several CANDUs. For some of these countries, the 'turn key' approach is required, in which the Canadian nuclear industry looks after everything up to the commissioning of the nuclear power plant, including the education and training of local nuclear engineers and plant personnel. Atomic Energy of Canada Limited (AECL) in particular has dispatched some personnel tasked to prepare and give short courses on some specific aspects of CANDU design and operation, but a lack of consistency was observed as different persons prepared and gave the courses rather independently. To address the many problems tied with nuclear engineering education, the CANTEACH program was set up involving major partners of the Canadian nuclear industry. Parts of the activities foreseen by CANTEACH consist in the writing of nuclear engineering textbooks and associated computer-based pedagogical material. The present paper discusses the main parts of two textbooks being produced, one in reactor physics at steady state and the other on nuclear fuel management. (author)

Full Text Available The purpose of this study is to analyze and compare the value of authentic materials and textbooks in ESP English for Specific Purposes learning and teaching context. The study compares the characteristics of the authentic materials and the characteristics of textbooks designed and selected for the purpose of teaching and learning English as a foreign language in ESP setting. The study defines the role of materials in ESP setting and compares the benefits and possible drawbacks of both types of materials and resources: the authentic materials in English for Specific Purposes context compared to traditional textbooks designed for the purpose of teaching and learning English for Specific Purposes. The study identifies the benefits of authentic materials, which include the richness as an input source and the authenticity of the tasks offered to learners, as well as the negative sides of authentic materials, which include the level of difficulty that these materials might present to the learner . Furthermore, the study identifies the benefits of textbooks, which include available sources for the learners and less time consuming class preparation for the teachers, as well as the drawbacks which include the impossibility of finding a textbook which corresponds entirely to learners’ needs. In addition, the article focuses on teachers’ attitudes and opinions regarding the appropriateness and exploitability of each source and their preferences and reasons for material selection. The target population consists of eleven lecturers who teach English for Specific Purposes in tertiary education. The lecturers teach various branches of ESP, including ESP for Computer Sciences, Business, Communication and Legal Studies. Data collection is conducted through a specifically designed questionnaire, addressing the questions of materials selection, teachers’ preferences regarding textbooks or authentic materials and the selection criteria applied by the

Effects of cavity on leakage loss in straight-through labyrinth seals

International Nuclear Information System (INIS)

Zhao, W; Nielsen, T K; Billdal, J T

2010-01-01

Labyrinth seals are widely used in rotating fluid machinery, due to its low-cost, simplicity and reliability. A straight-through labyrinth seal consists of a clearance between the stator and rotor, and sometimes cavities which are included on the stator or the rotator side. In this type of seals, making cavities are an effective way to convert turbulence kinetic energy into thermal energy by forming turbulence vortices, thereby reducing pressure difference and leakage flow. In this paper, the effect of cavities on leakage loss in straight-through labyrinth seals are studied by changing cavity dimensions such as depth and length, cavity number and cavity location. The influences of unilateral cavities and bilateral cavities on the leakage loss in straight-through labyrinth seals are also compared. The fluid flow characteristics through straight-through labyrinth seals were obtained by using viscous flow analysis along with a standard k-ωturbulence model. The cavity dimensions and cavity numbers have significant effects on the leakage as well as on the flow pattern in the seal. The bilateral cavity has better leakage performance than the unilateral cavity when cavity dimensions are identical. However, the cavity location shows no significant influences on the leakage flow.

Implanting straight into cochlea risks the facial nerve: a Cartesian coordinate study.

Science.gov (United States)

Deshpande, Anita S; Wendell Todd, N

2016-12-01

To describe the straight-into-cochlea line that affords the best access for an electrode array to enter via the round window, and how this line relates to the facial nerve, the incus, and mastoid size. The straight-into-cochlea line is important to minimize the cochlear trauma and maximize the likelihood of placement into the scala tympani. High-resolution CT scans were obtained for ten craniums with the extremes of large (N = 5) and small (N = 5) mastoid pneumatization; the specimens were from a series of 41 ear normal craniums. Using FIJI, a publicly available software program, the straight-into-cochlea insertion line was determined by defining the x-y-z coordinates of the middle of the round window and a point 6.0 mm into the cochlea on its centrifugal wall. Then, from the extended straight-into-cochlea insertion line, we determined the shortest perpendicular distance to the middle of the fallopian canal, and from that "fallopian point" to the apex of the posterior process of the incus. We found good repeatability of measurements. We found the extended straight-into-cochlea insertion lines routinely close to or in the midst of the fallopian canal (50 % ≤ 1.0 mm). We found the lines 4.7-7.8 mm from the apex of the posterior process of the incus. Line positions relative to "fallopian point" and incus showed no relation to mastoid pneumatization. For the distance "fallopian point" to incus, bilateral symmetry was suggested. Using landmarks registered in an x-y-z coordinate system, straight-into-cochlea insertion via the round window puts the facial nerve at risk.

Full Text Available English for Academic Purposes (EAP and English for Specific Purposes (ESP are developing branches of English as a Foreign Language (EFL instruction in Iran. These branches have a marginal status in the tertiary education, and the Ministry of Science, Research, and Technology’s high commission offers no clear guidance for selecting and developing basic academic instructional materials related to the linguistic or communicative standards expected by teachers (Mazdayasna & Tahririan, 2008. This paper tries to evaluate an ESP textbook written for BSc students of physics entitled, ‘English for the students of physics’, which is prepared by the Center for Studying and Compiling University Books in Humanities (SAMT. The present research was based on qualitative and quantitative research techniques and included two steps. First, internal, external and overall evaluation of the book was carried out based on McDonough & Shaw (1993 model. While conducting the external evaluation of the book, the intended audience, the proficiency level, the context of use, the language, the author's views on language and methodology, the inclusion of a vocabulary list/index, visual features, and the cultural aspects were examined. The internal evaluation included the presentation of the skills, grading and sequencing, discourse skills, listening section, the representation of different learning styles. And in overall evaluation, general suitability of the textbook was assessed. In the second step, six teachers each responded to a 22-item textbook evaluation questionnaire to express their perceptions concerning various aspects of the textbooks. The results revealed the extent of appropriateness of the textbook used by BSc students of physics. Suggestions are offered for the future revision and/or designing the textbooks.

A visual analysis of gender bias in contemporary anatomy textbooks.

Parker, Rhiannon; Larkin, Theresa; Cockburn, Jon

2017-05-01

Empirical research has linked gender bias in medical education with negative attitudes and behaviors in healthcare providers. Yet it has been more than 20 years since research has considered the degree to which women and men are equally represented in anatomy textbooks. Furthermore, previous research has not explored beyond quantity of representation to also examine visual gender stereotypes and, in light of theoretical advancements in the area of intersectional research, the relationship between representations of gender and representations of ethnicity, body type, health, and age. This study aimed to determine the existence and representation of gender bias in the major anatomy textbooks used at Australian Medical Schools. A systematic visual content analysis was conducted on 6044 images in which sex/gender could be identified, sourced from 17 major anatomy textbooks published from 2008 to 2013. Further content analysis was performed on the 521 narrative images, which represent an unfolding story, found within the same textbooks. Results indicate that the representation of gender in images from anatomy textbooks remain predominantly male except within sex-specific sections. Further, other forms of bias were found to exist in: the visualization of stereotypical gendered emotions, roles and settings; the lack of ethnic, age, and body type diversity; and in the almost complete adherence to a sex/gender binary. Despite increased attention to gender issues in medicine, the visual representation of gender in medical curricula continues to be biased. The biased construction of gender in anatomy textbooks designed for medical education provides future healthcare providers with inadequate and unrealistic information about patients.

First-year engineering students' use of their mathematics textbook - opportunities and constraints

Science.gov (United States)

Randahl, Mira

2012-09-01

The role of the mathematics textbook at tertiary level has received limited exposure in previous research although it is likely that students work individually and that some of this work depends on the use of the textbook. The aim of this study was to investigate the process of approaching the textbook from epistemological, cognitive, and didactical perspectives. The focus was on identifying and discussing the opportunities and constraints in the process. The study was an explorative case study and the participants were first-year engineering students taking a basic calculus course. The data were collected through questionnaires, observations, and interviews. Results showed that the textbook was used to a very low degree and mainly perceived as a source of tasks. Different opportunities and constraints are pointed out and some didactical implications are suggested. The results and discussion indicate that a need for greater awareness about the use of mathematical textbooks in meaningful ways at tertiary level.

Chiel, Hillel J; McManus, Jeffrey M; Shaw, Kendrick M

2010-01-01

We describe the development of a course to teach modeling and mathematical analysis skills to students of biology and to teach biology to students with strong backgrounds in mathematics, physics, or engineering. The two groups of students have different ways of learning material and often have strong negative feelings toward the area of knowledge that they find difficult. To give students a sense of mastery in each area, several complementary approaches are used in the course: 1) a "live" textbook that allows students to explore models and mathematical processes interactively; 2) benchmark problems providing key skills on which students make continuous progress; 3) assignment of students to teams of two throughout the semester; 4) regular one-on-one interactions with instructors throughout the semester; and 5) a term project in which students reconstruct, analyze, extend, and then write in detail about a recently published biological model. Based on student evaluations and comments, an attitude survey, and the quality of the students' term papers, the course has significantly increased the ability and willingness of biology students to use mathematical concepts and modeling tools to understand biological systems, and it has significantly enhanced engineering students' appreciation of biology.

At the 2.5-GeV ring of the Photon Factory, a large reconstruction of the lattice around the straight sections has been accomplished in 2005. Thus reconstruction is the main part of the straight-sections upgrade project to rebuild existing undulators and to increase the number of undulator beamlines. As a result of the reconstruction, four short straight sections have been newly created and the lengths of the existing straight sections have been much extended. To exploit the new straight sections, short-period narrow-gap undulators which have a sufficiently high brilliance in hard x-ray range have been developed. The reconstruction work of the ring was completed in a seven-month shutdown from March to September, 2005. In the area over two thirds of the storage ring, all the quadrupole magnets and all the beam ducts have been renewed and rearranged to construct the new lattice. Recommissioning of the storage ring was finished at the end of October, 2005. Though we made no in-situ baking for the beam ducts, recovery of the beam lifetime has favorably progressed due to the vacuum scrubbing by the synchrotron radiation

Straight-Line Target Tracking for Unmanned Surface Vehicles

Directory of Open Access Journals (Sweden)

Morten Breivik

2008-10-01

Full Text Available This paper considers the subject of straight-line target tracking for unmanned surface vehicles (USVs. Target-tracking represents motion control scenarios where no information about the target behavior is known in advance, i.e., the path that the target traverses is not defined apriori. Specifically, this work presents the design of a motion control system which enables an underactuated USV to track a target that moves in a straight line at high speed. The motion control system employs a guidance principle originally developed for interceptor missiles, as well as a novel velocity controller inspired by maneuverability and agility concepts found in fighter aircraft literature. The performance of the suggested design is illustrated through full-scale USV experiments in the Trondheimsfjord.

Posology of insulins: A review of standard textbooks and product inserts

2015-01-01

Full Text Available Objectives: The study is aimed to assess whether the information contained in standard pharmacology, endocrinology, and diabetology textbooks regarding timings of administration, frequency and dose of various insulins is adequate and also to see whether the information contained in these texts is concordant with product inserts. Materials and Methods: Four standard textbooks of pharmacology, two of diabetology and three of endocrinology were assessed for the published information regarding dose, timing, and frequency of insulin administration. The product inserts of commonly available insulins in India were also studied for the same. Results: Various omissions and disparities could be seen in the coverage of insulins in standard textbooks. Posology information about premixed insulins and basal insulins have been omitted by the majority of the textbooks. Details about dose, frequency and timings of ultra-short acting insulins have also not been covered by all textbooks. Some discrepancies regarding prescribing information was also noted in product inserts, especially in case of newer insulins. Conclusions: Thus, this article stresses upon the need of a uniform source of information for providing adequate and standardized knowledge regarding timing, frequency, and dose of insulins.

Toward textbook multigrid efficiency for fully implicit resistive magnetohydrodynamics

Adams, Mark F.; Samtaney, Ravi; Brandt, Achi

2010-01-01

Multigrid methods can solve some classes of elliptic and parabolic equations to accuracy below the truncation error with a work-cost equivalent to a few residual calculations - so-called 'textbook' multigrid efficiency. We investigate methods to solve the system of equations that arise in time dependent magnetohydrodynamics (MHD) simulations with textbook multigrid efficiency. We apply multigrid techniques such as geometric interpolation, full approximate storage, Gauss-Seidel smoothers, and defect correction for fully implicit, nonlinear, second-order finite volume discretizations of MHD. We apply these methods to a standard resistive MHD benchmark problem, the GEM reconnection problem, and add a strong magnetic guide field, which is a critical characteristic of magnetically confined fusion plasmas. We show that our multigrid methods can achieve near textbook efficiency on fully implicit resistive MHD simulations.

Wiegant, Fred; Scager, Karin; Boonstra, Johannes

2011-01-01

This article reports on a one-semester Advanced Cell Biology course that endeavors to bridge the gap between gaining basic textbook knowledge about cell biology and learning to think and work as a researcher. The key elements of this course are 1) learning to work with primary articles in order to get acquainted with the field of choice, to learn scientific reasoning, and to identify gaps in our current knowledge that represent opportunities for further research; 2) formulating a research project with fellow students; 3) gaining thorough knowledge of relevant methodology and technologies used within the field of cell biology; 4) developing cooperation and leadership skills; and 5) presenting and defending research projects before a jury of experts. The course activities were student centered and focused on designing a genuine research program. Our 5-yr experience with this course demonstrates that 1) undergraduate students are capable of delivering high-quality research designs that meet professional standards, and 2) the authenticity of the learning environment in this course strongly engages students to become self-directed and critical thinkers. We hope to provide colleagues with an example of a course that encourages and stimulates students to develop essential research thinking skills.

Explaining Dimensions of Middle School Mathematics Teachers’ Use of Textbooks

2012-12-01

Full Text Available Abstract The purpose of the study was to describe middle school mathematics teachers’ use of textbooks. For this purpose, the Use of Mathematics Textbooks Questionnaire was distributed to 531 middle school mathematics teachers. The results of the study showed that teachers used the student edition textbook during the class and prior to class; and mostly read it for the topic, but rarely for problems and examples. Teachers frequently selected questions from the workbook that were not included in the student edition textbook. They frequently used questions in the workbook similar to the ones in the high school entrance exam questions. They used the teacher edition textbook to read the curriculum objectives and to prepare for the class but they very rarely tended to look up the answers of the questions from the teacher edition textbook.

Suderman, Bethany L; Vasavada, Anita N

2017-08-01

Musculoskeletal models of the cervical spine commonly represent neck muscles with straight paths. However, straight lines do not best represent the natural curvature of muscle paths in the neck, because the paths are constrained by bone and soft tissue. The purpose of this study was to estimate moment arms of curved and straight neck muscle paths using different moment arm calculation methods: tendon excursion, geometric, and effective torque. Curved and straight muscle paths were defined for two subject-specific cervical spine models derived from in vivo magnetic resonance images (MRI). Modeling neck muscle paths with curvature provides significantly different moment arm estimates than straight paths for 10 of 15 neck muscles (p straight lines to model muscle paths can lead to overestimating neck extension moment. However, moment arm methods for curved paths should be investigated further, as different methods of calculating moment arm can provide different estimates.

Full Text Available Assessment and evaluation instruments provide teachers the opportunity of shaping education in the beginning, contributing to education during the process and evaluating education at the end of the process. Textbooks, on the other hand, are resources that present the aforementioned contributions to teachers at first hand. Thus, the study aims to compare the distribution of assessment and evaluation instruments in the physics textbooks being used in the academic year of 2011- 2012 and 2016-2017 according to units, settlement within units and types of assessment instruments that are used. For that purpose, 9, 10, 11 and 12th grade textbooks being used in physics lessons in the academic year of 2011-2012 and 2016-2017 were examined via document analysis method. As a result of the study, it was determined that the highest number of assessment instruments in physics textbooks from two different years was encountered in the unit of force and motion. The reason for this unit having higher number of questions could be associated with higher number of mathematical operations in the unit intended for allowing students to overcome their mathematical deficiencies by practicing such questions. It was observed that the number of questions was increased especially in the books being used in the academic year of 2016-2017 and alternative assessment instruments were fewer than traditional assessment instruments. Traditional assessment instruments are still used very frequently in the textbooks, which proves the effect of traditional approaches in assessment and evaluation. Another reason for this condition is that a result-oriented evaluation is used in the university entrance exam. In the light of these results, it is suggested to make the university exam student-centered rather than making an arrangement in textbooks.

A generalized, periodic nonlinearity-reduced interferometer for straightness measurements

International Nuclear Information System (INIS)

Wu Chienming

2008-01-01

Periodic nonlinearity is a systematic error limiting the accuracy of displacement measurements at the nanometer level. However, an interferometer with a displacement measurement accuracy of less than 1 nm is required in nanometrology and in fundamental scientific research. To meet this requirement, a generalized, periodic nonlinearity-reduced interferometer, based on three construction principles has been developed for straightness measurements. These three construction principles have resulted in an interferometer with a highly stable design with reduced periodic nonlinearity. Verifications by a straightness interferometer have demonstrated that the periodic nonlinearity was less than 40 pm. The results also demonstrate that the interferometer design is capable of subnanometer accuracy and is useful in nanometrology

Friends with benefits, but without the sex: straight women and gay men exchange trustworthy mating advice.

Russell, Eric M; DelPriore, Danielle J; Butterfield, Max E; Hill, Sarah E

2013-02-09

Although research has made progress in elucidating the benefits exchanged within same- and opposite-sex friendships formed between heterosexual men and women, it is less clear why straight women and gay men form close relationships with one another. The current experiments begin to address this question by exploring a potential benefit hypothesized to be uniquely available to straight women and gay men in the context of these friendships: trustworthy mating advice. Experiment 1 revealed that straight women perceive mating-relevant advice from a gay man to be more trustworthy than similar advice offered by a straight man or woman. Experiment 2 demonstrated that gay men perceive mating advice offered by a straight woman to be more trustworthy than advice offered by a lesbian woman or another gay man. Overall, the results provide initial experimental evidence that relationships between gay men and straight women may be characterized by a mutual exchange of mating-relevant benefits in the absence of sexual interest or competition.

2015-12-01

Full Text Available Abstract The present study was an attempt to investigate and compare the efficiency of the new and the old first grade high school English textbooks by focusing on thirty teachers and three hundred learners’ attitudes through a textbook evaluation checklist and a questionnaire. The analysis of the results revealed that, with regard to teachers' attitude toward the two books compared with each other, these books were nearly the same with regard to pronunciation and exercises. The old book was considered more efficient regarding grammar. Regarding the rest of the items, the new book was more efficient. Taking the learners perspective into account toward these two books compared with each other, there were no noteworthy difference between the books regarding vocabulary. Regarding the other items, the new book was considered more efficient. The findings of this study can assist decision-makers to pay more attention to the evaluation of textbooks and consequently the selection of an appropriate book according to the teachers and learners’ expectations, needs and interests.

Biospies of brain lesions with unknown entity are an everyday procedure among many neurosurgical departments. Biopsies can be performed frame-guided or frameless. However, cerebellar lesions are a special entity with a more complex approach. All biopsies in this study were performed stereotactically frame guided. Therefore, only biopsies of cerebellar lesions were included in this study. We compared whether the frame was attached straight versus oblique and we focused on diagnostic yield and complication rate. We evaluated 20 patients who underwent the procedure between 2009 and 2017. Median age was 56.5 years. 12 (60%) Patients showed a left sided lesion, 6 (30%) showed a lesion in the right cerebellum and 2 (10%) patients showed a midline lesion. The stereotactic frame was mounted oblique in 12 (60%) patients and straight in 8 (40%) patients. Postoperative CT scan showed small, clinically silent blood collection in two (10%) of the patients, one (5%) patient showed haemorrhage, which caused a hydrocephalus. He received an external ventricular drain. In both patients with small haemorrhage the frame was positioned straight, while in the patient who showed a larger haemorrhage the frame was mounted oblique. In all patients a final histopathological diagnosis was established. Cerebellar lesions of unknown entity can be accessed transcerebellar either with the stereotactic frame mounted straight or oblique. Also for cerebellar lesions the procedure shows a high diagnostic yield with a low rate of severe complications, which need further treatment.

This study examined the influence of knee angle on the cardiorespiratory system loading during submaximal and maximal stationary cycle ergometry. Experimental design and participants: eighteen untrained women (age: 21+/-1.88 years, weight: 57+/-5.75 kg, height: 165+/-5.03 cm, values are mean+/-SD) volunteered as subjects and underwent two-cycle ergometer incremental (Jaeger ER900) tests: 1) straight knee (180 degrees), 2) bent knee (140 degrees). oxygen uptake (VO2), ventilation (VE) and respiratory exchange ratio (RER) were measured continuously during each test using an open circuit spirometry and blood lactate concentration was determined by means of an enzymatic method. Comparing cycling with "straight knee" to cycling with "bent knee" at 50 W, heart rate (HR), V(E) and VO2 were significantly higher (10.6%, 12.5%, 17.8%). At 100 W, blood lactate was significantly lower (10.8%) while VO2 and RER was higher (5.5%, 7.1%). During maximal exercise, the total exercise time was significantly longer (11.2%) and VE, VO2 and HR were significantly higher during cycling with "straight knee" compared to cycling with "bent knee". No significant difference in peak lactate was evident between the two sitting positions. The results of this study indicate that cycling with bent knee requires lower oxygen uptake while pedaling with straight knee is the only way to reach VO2max during cycle testing, since the cardiorespiratory system is fully taxed.

Gender stereotyping in EFL grammar textbooks. A diachronic approach

Directory of Open Access Journals (Sweden)

Marcin Lewandowski

2014-12-01

Full Text Available Gender stereotyping in educational materials (especially in EFL textbooks has been a common theme in linguistic research (cf., e. g., Hellinger 1980; Porreca 1984; Freebody/Baker 1987; Sunderland 1994; Lee/Collins 2010. However, very little attention has been paid to the representation of men and women in EFL/ESL grammar textbooks; i. e. the way both genders are portrayed in constructed examples of usage and practice sentences. The present contribution is intended to fill this gap. The paper investigates the scope of gender stereotyping from a diachronic perspective: it seeks to demonstrate whether and how the images of men and women have changed following the dissemination of guidelines for non-sexist language and equal treatment of the two genders in English language educational materials. To this aim, two corpora have been compiled. The first one includes sentences derived from three EFL textbooks published in the 1970s and 1980s, while the other one contains analogous data from three 21st century titles. The contrastive analysis of the sentences in the two corpora across 11 semantic domains has found that the recently published grammar textbooks portray the two genders in a much less stereotyped way than the 20th century course books.

Toward textbook multigrid efficiency for fully implicit resistive magnetohydrodynamics

KAUST Repository

Adams, Mark F.; Samtaney, Ravi; Brandt, Achi

2010-01-01

Multigrid methods can solve some classes of elliptic and parabolic equations to accuracy below the truncation error with a work-cost equivalent to a few residual calculations so-called "textbook" multigrid efficiency. We investigate methods to solve the system of equations that arise in time dependent magnetohydrodynamics (MHD) simulations with textbook multigrid efficiency. We apply multigrid techniques such as geometric interpolation, full approximate storage, Gauss-Seidel smoothers, and defect correction for fully implicit, nonlinear, second-order finite volume discretizations of MHD. We apply these methods to a standard resistive MHD benchmark problem, the GEM reconnection problem, and add a strong magnetic guide field, which is a critical characteristic of magnetically confined fusion plasmas. We show that our multigrid methods can achieve near textbook efficiency on fully implicit resistive MHD simulations. (C) 2010 Elsevier Inc. All rights reserved.

Efficient odd straight medium chain free fatty acid production by metabolically engineered Escherichia coli.

Science.gov (United States)

Wu, Hui; San, Ka-Yiu

2014-11-01

Free fatty acids (FFAs) can be used as precursors for the production of biofuels or chemicals. Different composition of FFAs will be useful for further modification of the biofuel/biochemical quality. Microbial biosynthesis of even chain FFAs can be achieved by introducing an acyl-acyl carrier protein thioesterase gene into E. coli. In this study, odd straight medium chain FFAs production was investigated by using metabolic engineered E. coli carrying acyl-ACP thioesterase (TE, Ricinus communis), propionyl-CoA synthase (Salmonella enterica), and β-ketoacyl-acyl carrier protein synthase III (four different sources) with supplement of extracellular propionate. By using these metabolically engineered E. coli, significant quantity of C13 and C15 odd straight-chain FFAs could be produced from glucose and propionate. The highest concentration of total odd straight chain FFAs attained was 1205 mg/L by the strain HWK201 (pXZ18, pBHE2), and 85% of the odd straight chain FFAs was C15. However, the highest percentage of odd straight chain FFAs was achieved by the strain HWK201 (pXZ18, pBHE3) of 83.2% at 48 h. This strategy was also applied successfully in strains carrying different TE, such as the medium length acyl-ACP thioesterase gene from Umbellularia californica. C11 and C13 became the major odd straight-chain FFAs. © 2014 Wiley Periodicals, Inc.

Most of these books belong to medical genetics, followed by general genetics, while the books on plant genetics, animal genetics or microbial genetics are relatively few. In these search results, 91 had the same name of Medical Genetics, professor Ji Zuo is the most productive author, who edited 9 genetics textbooks, and Science Press Ltd. is the most productive press, which published 179 (20%) genetics textbooks. The questionnaire survey showed that "Genetics" (Second Edition) edited by Zhuohua Dai is the most widely used textbooks in the Chinese colleges, while the mainly used experimental books are the handouts or self-edited textbooks. Finally, we analyzed the problems currently existed in the textbooks, such as slowly updating cycle, less supports, lots of books with the same name, lack of scientific stories, very rare and unique illustrations, too full printed pages, and also provided the proposed solution.
