    As teachers committed to educating all students, we need to learn more about how instructional materials shape representations of sexuality and gender. Through its insistent deconstruction of the norms that structure practice and belief, queer theory offers perspectives from which science educators can question assumptions embedded in textbooks. This article applies queer theory to analyze eight biology textbooks used in the United States. Specifically, we ask how biology textbooks address sexuality outside the heterosexual norm and if they propagate heteronormative attitudes. The textbooks examined offer deafening silences, antiseptic factoids, socially sanitized concepts, and politically correct binary-gendered illustrations. In these textbooks, the term homosexuality was used only in the context of AIDS where, along with iv drug users, they were identified as an affected group. The pervasive acceptance of heteronormative behavior privileges students that fit the heterosexual norm, and oppresses through omission and silence those who do not. We offer implications for practice to help science educators broaden their perspectives on the constructs of sexuality and gender to construct new ways of knowing and understanding differences in science classrooms and the natural world.

  2. Queering animal sexual behavior in biology textbooks

    Full Text Available Biology is instrumental in establishing and perpetuating societal norms of gender and sexuality, owing to its afforded authoritative role in formulating beliefs about what is "natural". However, philosophers, historians, and sociologists of science have shown how conceptions of gender and sexuality pervade the supposedly objective knowledge produced by the natural sciences. For example, in describing animal relationships, biologists sometimes use the metaphor of marriage, which brings with it conceptions of both cuckoldry and male ownership of female partners. These conceptions have often led researchers to overlook female behavior and adaptations, such as female initiation of mating. Such social norms and ideologies influence both theories and research in biology. Social norms of gender and sexuality also influence school cultures. Although awareness of gender issues has had a major impact in Sweden during recent years, the interventions conducted have been based on a heteronormative understanding of sex; this has rendered sexual norms a non-prioritized issue and thereby rendered non-heterosexuals invisible in teaching and textbooks. Since this research was published in 2007 and 2009, norm critical pedagogics have been included in the Swedish National Agency for Education's guidelines for teaching. This inclusion represents one way to tackle the recurring problem of heterosexuality being described as a naturalized "normal" behavior and homosexuals, bisexuals and transsexuals being described from a heteronormative perspective. In this paper, I employ gender and queer perspectives to scrutinize how animal sexual behavior is described and explained in Swedish biology textbooks. The analysis is based in gender and queer theory, feminist science studies, and evolutionary biology. The article begins with an outline a discussion of my theoretical framework, relating gender and queer perspectives on evolutionary biology to a discussion of queer

  3. Contextualization and technologies in the Biology and Chemistry textbooks

    Full Text Available We analyze Biology and Chemistry school textbooks to understand how conceptions of contextualization and technologies are overtaken and hybridized. We consider that textbooks produce meanings (senses and signifieds in curricular policies. These are cultural productions that were hybridized and recontextualized according to Basil Bernstein and Stephen Ball. We argue that the focus on contextualization and technologies expressed in those textbooks are hybridized from several influences and they do not represent a consensus about those conceptions.

  5. ``Sex Hormones'' in Secondary School Biology Textbooks

    Nehm, Ross H.; Young, Rebecca

    2008-11-01

    This study explores the extent to which the term “sex hormone” is used in science textbooks, and whether the use of the term “sex hormone” is associated with pre-empirical concepts of sex dualism, in particular the misconceptions that these so-called “sex hormones” are sex specific and restricted to sex-related physiological functioning. We found that: (1) all the texts employed the term “sex hormone”; (2) in all texts estrogen is characterized as restricted to females and testosterone is characterized as restricted to males; and (3) in all texts testosterone and estrogen are discussed as exclusively involved in sex-related physiological roles. We conclude that (1) contemporary science textbooks preserve sex-dualistic models of steroid hormones (one sex, one “sex hormone”) that were rejected by medical science in the early 20th century and (2) use of the term “sex hormone” is associated with misconceptions regarding the presence and functions of steroid hormones in male and female bodies.

  6. Sex Education Representations in Spanish Combined Biology and Geology Textbooks

    2013-07-01

    Sex education is principally dealt with as part of the combined subject of Biology and Geology in the Spanish school curriculum. Teachers of this subject are not specifically trained to teach sex education, and thus the contents of their assigned textbooks are the main source of information available to them in this field. The main goal of this study was to determine what information Biology and Geology textbooks provide with regard to sex education and the vision of sexuality they give, but above all to reveal which perspectives of sex education they legitimise and which they silence. We analysed the textbooks in question by interpreting both visual and text representations, as a means of enabling us to investigate the nature of the discourse on sex education. With this aim, we have used a qualitative methodology, based on the content analysis. The main analytical tool was an in-house grid constructed to allow us to analyse the visual and textual representations. Our analysis of the combined Biology and Geology textbooks for Secondary Year 3 revealed that there is a tendency to reproduce models of sex education that take place within a framework of the more traditional discourses. Besides, the results suggested that the most of the sample chosen for this study makes a superficial, incomplete, incorrect or biased approach to sex education.

  7. Positioning Genomics in Biology Education: Content Mapping of Undergraduate Biology Textbooks

    Directory of Open Access Journals (Sweden)

    Naomi L. B. Wernick

    2014-07-01

    Full Text Available Biological thought increasingly recognizes the centrality of the genome in constituting and regulating processes ranging from cellular systems to ecology and evolution. In this paper, we ask whether genomics is similarly positioned as a core concept in the instructional sequence for undergraduate biology. Using quantitative methods, we analyzed the order in which core biological concepts were introduced in textbooks for first-year general and human biology. Statistical analysis was performed using self-organizing map algorithms and conventional methods to identify clusters of terms and their relative position in the books. General biology textbooks for both majors and nonmajors introduced genome-related content after text related to cell biology and biological chemistry, but before content describing higher-order biological processes. However, human biology textbooks most often introduced genomic content near the end of the books. These results suggest that genomics is not yet positioned as a core concept in commonly used textbooks for first-year biology and raises questions about whether such textbooks, or courses based on the outline of these textbooks, provide an appropriate foundation for understanding contemporary biological science.

    We redesigned the undergraduate introductory biology course by writing a new textbook (Integrating Concepts in Biology [ICB]) that follows first principles of learning. Our approach emphasizes primary data interpretation and the utility of mathematics in biology, while de-emphasizing memorization. This redesign divides biology into five big ideas (information, evolution, cells, emergent properties, homeostasis), addressing each at five levels of organization (molecules, cells, organisms, populations, ecological systems). We compared our course outcomes with two sections that used a traditional textbook and were taught by different instructors. On data interpretation assessments administered periodically during the semester, our students performed better than students in the traditional sections (p = 0.046) and exhibited greater improvement over the course of the semester (p = 0.015). On factual content assessments, our students performed similarly to students in the other sections (p = 0.737). Pre- and postsemester assessment of disciplinary perceptions and self-appraisal indicate that our students acquired a more accurate perception of biology as a discipline and may have developed a more realistic evaluation of their scientific abilities than did the control students (p < 0.05). We conclude that ICB improves critical thinking, metacognition, and disciplinary perceptions without compromising content knowledge in introductory biology. PMID:23463233

  10. Introductory Biology Textbooks Under-Represent Scientific Process

    2011-08-01

    Full Text Available Attrition of undergraduates from Biology majors is a long-standing problem. Introductory courses that fail to engage students or spark their curiosity by emphasizing the open-ended and creative nature of biological investigation and discovery could contribute to student detachment from the field. Our hypothesis was that introductory biology books devote relatively few figures to illustration of the design and interpretation of experiments or field studies, thereby de-emphasizing the scientific process.To investigate this possibility, we examined figures in six Introductory Biology textbooks published in 2008. On average, multistep scientific investigations were presented in fewer than 5% of the hundreds of figures in each book. Devoting such a small percentage of figures to the processes by which discoveries are made discourages an emphasis on scientific thinking. We suggest that by increasing significantly the illustration of scientific investigations, textbooks could support undergraduates’ early interest in biology, stimulate the development of design and analytical skills, and inspire some students to participate in investigations of their own.

  13. How do the high school biology textbooks introduce the nature of science?

    Although helping students to achieve an adequate understanding of the nature of science has been a consistent goal for science education for over half a century, current research reveals that the majority of students and teachers have naive views of the nature of science (Abd-El-khalick & Akerson, 2004; Bianchini & Colburn, 2000). This problem could be attributed not only to the complex nature of science, but also to the way the nature of science is presented to students during instruction. Thus, research must be conducted to examine how the science is taught, especially in science textbooks, which are a major instructional resource for teaching science. The aim of this study was to conduct a content analysis of the first chapter of four high school biology textbooks, which typically discusses "What is science?" and "What is biology?" This research used a content analysis technique to analyze the four high school biology textbooks, using a conceptual framework that has been used often for science textbook analysis. This conceptual framework consists of four themes of the nature of science: (a) science as a body of knowledge, (b) science as a way of thinking, (c) science as a way of investigating, and (d) the interaction of science, technology, and society. For this study, the four-theme-framework was modified to incorporate descriptors from national-level documents, such as Science for All Americans (AAAS, 1990) Benchmarks for Science Literacy (AAAS, 1993) and the National Science Education Standards (NRC, 1996), as well as science education research reports. A scoring procedure was used that resulted in good to excellent intercoder agreement with Cohen's kappa (k) ranging from .63 to .96. The findings show that the patterns of presentation of the four themes of the nature of science in the four high school biology textbooks are similar across the different locations of data, text, figures, and assessments. On the other hand, the pattern of presentation of the four

  18. From Fertilization to Birth: Representing Development in High School Biology Textbooks

    Science.gov (United States)

    Wellner, Karen L.

    Biology textbooks are everybody's business. In accepting the view that texts are created with specific social goals in mind, I examined 127 twentieth-century high school biology textbooks for representations of animal development. Paragraphs and visual representations were coded and placed in one of four scientific literacy categories: descriptive, investigative, nature of science, and human embryos, technology, and society (HETS). I then interpreted how embryos and fetuses have been socially constructed for students. I also examined the use of Haeckel's embryo drawings to support recapitulation and evolutionary theory. Textbooks revealed that publication of Haeckel's drawings was influenced by evolutionists and anti-evolutionists in the 1930s, 1960s, and the 1990s. Haeckel's embryos continue to persist in textbooks because they "safely" illustrate similarities between embryos and are rarely discussed in enough detail to understand comparative embryology's role in the support of evolution. Certain events coincided with changes in how embryos were presented: (a) the growth of the American Medical Association (AMA) and an increase in birth rates (1950s); (b) the Biological Sciences Curriculum Study (BSCS) and public acceptance of birth control methods (1960s); (c) Roe vs. Wade (1973); (d) in vitro fertilization and Lennart Nilsson's photographs (1970s); (e) prenatal technology and fetocentrism (1980s); and (f) genetic engineering and Science-Technology-Society (STS) curriculum (1980s and 1990s). By the end of the twentieth century, changing conceptions, research practices, and technologies all combined to transform the nature of biological development. Human embryos went from a highly descriptive, static, and private object to that of sometimes contentious public figure. I contend that an ignored source for helping move embryos into the public realm is schoolbooks. Throughout the 1900s, authors and publishers accomplished this by placing biology textbook embryos and

  4. Ella Thea Smith and the lost history of American high school biology textbooks.

    Ladouceur, Ronald P

    2008-01-01

    Two influential articles published in the 1970s suggested that pressure from Christian fundamentalists, subsequent to the Scopes trial of 1925, forced American high school biology textbook authors and publishers to significantly limit discussion of the topic of evolution. The conclusions reached by these studies have become foundational for historians examining the interplay between science and religion in the United States in the twentieth century. However, a reexamination of key twentieth century biology textbooks suggests that the narrative that the treatment of the theory of evolution was held hostage to anti-rational cultural forces is largely a myth, created first as part of a public relations effort by the Biological Sciences Curriculum Study (BSCS) to differentiate, defend, and promote its work, and later as part of an attempt by scholars to sound a warning concerning the rise of the religious right. A focus on this narrative has not only allowed biologists to sidestep uncomfortable questions regarding the race-biased and class-biased assumptions embedded within the concept of evolutionary progress, it has also limited reliance on the texts in question as reliable reflections of the cultural assumptions of educators and scientists. A reexamination of the most popular American biology textbooks from 1907 to 1963, particularly the work of Ella Thea Smith, provides evidence in support of these contentions.

    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.

The experimental design was a randomized block in factorial arrangement (2 x 10: 10 winter cover crops systems (Fallow [control], black oats, white oats, ryegrass, forage turnip, vetch, white lupine; black oat + forage turnip; black oat + vetch and black oat + vetch + fodder turnip, and two nitrogen rates in the form of urea applied in successive crops of beans common and maize, with four replications. We assessed the biological attributes (Margalef’s richness, Simpson’s dominance, Shannon’s diversity and abundance of organisms and microbiological (carbon and nitrogen microbial biomass, basal respiration, metabolic quotient and microbial quotient of the soil. The fallow with wild species and white lupine showed greater Simpson’s dominance and abundance of organisms due to the increase in the number of individuals of the order Collembola. Vetch improved the biological attributes of the soil with increase in Collembola abundance and diversity of organisms of soil fauna. The application of nitrogen favored the microbial biomass carbon and reduced the metabolic quotient.

  12. Pedagogic discourse in introductory classes: Multi-dimensional analysis of textbooks and lectures in biology and macroeconomics

    Carkin, Susan

    The broad goal of this study is to represent the linguistic variation of textbooks and lectures, the primary input for student learning---and sometimes the sole input in the large introductory classes which characterize General Education at many state universities. Computer techniques are used to analyze a corpus of textbooks and lectures from first-year university classes in macroeconomics and biology. These spoken and written variants are compared to each other as well as to benchmark texts from other multi-dimensional studies in order to examine their patterns, relations, and functions. A corpus consisting of 147,000 words was created from macroeconomics and biology lectures at a medium-large state university and from a set of nationally "best-selling" textbooks used in these same introductory survey courses. The corpus was analyzed using multi-dimensional methodology (Biber, 1988). The analysis consists of both empirical and qualitative phases. Quantitative analyses are undertaken on the linguistic features, their patterns of co-occurrence, and on the contextual elements of classrooms and textbooks. The contextual analysis is used to functionally interpret the statistical patterns of co-occurrence along five dimensions of textual variation, demonstrating patterns of difference and similarity with reference to text excerpts. Results of the analysis suggest that academic discourse is far from monolithic. Pedagogic discourse in introductory classes varies by modality and discipline, but not always in the directions expected. In the present study the most abstract texts were biology lectures---more abstract than written genres of academic prose and more abstract than introductory textbooks. Academic lectures in both disciplines, monologues which carry a heavy informational load, were extremely interactive, more like conversation than academic prose. A third finding suggests that introductory survey textbooks differ from those used in upper division classes by being

    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."

    While education communities have well defined commitments to protect their learners from oppressive instructional materials, discourses of science education are often left unexamined. This analysis/critique employs queer theory as a perspective to look at how one widely used textbook in Ontario schools conceptualizes notions of gender and sexuality. Results indicate the use of discourses that promote exclusively heteronormative constructions of sexuality along with sex/gender binaries. Challenging such oppressive misconceptions of sex/gender and sexuality is discussed.

    Implementation of evolution lectures at Biology Department Faculty of Mathematics and Natural Sciences State University of Padang has been considered not optimal. The reasons are the limited availability of textbooks and students' learning attitudes. Because currently the students are very familiar with the internet and even has become a necessity, it has developed textbooks of evolution based on ICT and metacognitive. Selection of ICT based is in order to optimize the utilization of multimedia, and this is very compatible with the development of learning technology. While metacognitive based is in order to train students' learning attitudes to be able to think analysis, creative and evaluative. The aim of this study is to determine the effect of the use of evolution textbooks based on ICT and metacognitive to the cognitive competence of students of Biology Department State University of Padang. The data of this research is students' cognitive competence obtained from the implementation of effectiveness test of evolution textbook in the form of student learning outcomes. The research instrument is a learning result test designed to determine students’ cognitive competence. The subject of the study is a group of students in evolution course consisting of 33 students. Lectures are conducted through face-to-face and online lectures on Edmodo’s platform. The result of data analysis shows that there is an increase of cognitive competence of biology students after learning using ICT and metacognitive based evolution textbook, where average achievement is 77.72 with Percentage of achievement of criteria mastery is 81.25%. Therefore, it can be concluded that the evolution textbook based on ICT and metacognitive is effective in improving cognitive competence of students of Biology Department, Universitas Negeri Padang.

  17. Justifying molecular images in cell biology textbooks: From constructions to primary data.

    Serpente, Norberto

    2016-02-01

    For scientific claims to be reliable and productive they have to be justified. However, on the one hand little is known on what justification precisely means to scientists, and on the other the position held by philosophers of science on what it entails is rather limited; for justifications customarily refer to the written form (textual expressions) of scientific claims, leaving aside images, which, as many cases from the history of science show are relevant to this process. The fact that images can visually express scientific claims independently from text, plus their vast variety and origins, requires an assessment of the way they are currently justified and in turn used as sources to justify scientific claims in the case of particular scientific fields. Similarly, in view of the different nature of images, analysis is required to determine on what side of the philosophical distinction between data and phenomena these different kinds of images fall. This paper historicizes and documents a particular aspect of contemporary life sciences research: the use of the molecular image as vehicle of knowledge production in cell studies, a field that has undergone a significant shift in visual expressions from the early 1980s onwards. Focussing on textbooks as sources that have been overlooked in the historiography of contemporary biomedicine, the aim is to explore (1) whether the shift of cell studies, entailing a superseding of the optical image traditionally conceptualised as primary data, by the molecular image, corresponds with a shift of justificatory practices, and (2) to assess the role of the molecular image as primary data. This paper also explores the dual role of images as teaching resources and as resources for the construction of knowledge in cell studies especially in its relation to discovery and justification. Finally, this paper seeks to stimulate reflection on what kind of archival resources could benefit the work of present and future epistemic

    Full Text Available The criticism of the current language in school textbooks indicates the gravity of this problem in our environment and the need to solve it. The first step in approaching this problem is studying the reception of primary school textbooks. In the first part of the paper we discuss all primary school textbooks from the fifth to the eighth grade with regard to the frequency of textbook usage and the perception of the difficulty of textbook language. In the second part of the paper there is an additional analysis of history, geography, biology, physics and chemistry textbooks from the fifth to the eighth grade with regard to the reasons for which pupils find them difficult. This preliminary research comprised in total 120 pupils from an urban school, thirty from each fifth to eighth grade. We analyzed the textbooks of the Institute for Textbook Publishing and Teaching Aids, which are used most frequently in our educational practice, and hence can represent the general situation of the problem. Bearing in mind the limited size of the sample of pupils, the results are used only as an illustration and should encourage new studies on a more extensive sample. Textbook language is often difficult since it is mostly insufficiently comprehensible, longwinded and with many data. In natural sciences, physics and chemistry, pupils give up studying from the textbook. The textbooks in narrative subjects lead the way with respect to their usage, among which everybody finds history textbooks most difficult. Geography and biology textbooks were evaluated differently, depending on the grade and success of the pupils declaring themselves. The results present a guideline to the current and new writers of our textbooks, critics and publishing houses.

    Forested catchments are generally assumed to provide higher quality water in opposition to agricultural and urban catchments. However, this should be tested in various ecological contexts and through the study of multiple variables describing water quality. Indeed, interactions between ecological variables, multiple land use and land cover (LULC) types, and water quality variables render the relationship between forest cover and water quality highly complex. Furthermore, the question of the scale at which land use within stream catchments most influences stream water quality and ecosystem health remains only partially answered. This paper quantifies, at the regional scale and across five natural ecoregions of Wallonia (Belgium), the forest cover effect on biological water quality indices (based on diatoms and macroinvertebrates) at the riparian and catchment scales. Main results show that forest cover - considered alone - explains around one third of the biological water quality at the regional scale and from 15 to 70% depending on the ecoregion studied. Forest cover is systematically positively correlated with higher biological water quality. When removing spatial, local morphological variations, or population density effect, forest cover still accounts for over 10% of the total biological water quality variation. Partitioning variance shows that physico-chemical water quality is one of the main drivers of biological water quality and that anthropogenic pressures often explain an important part of it (shared or not with forest cover). The proportion of forest cover in each catchment at the regional scale and across all ecoregions but the Loam region is more positively correlated with high water quality than when considering the proportion of forest cover in the riparian zones only. This suggests that catchment-wide impacts and a fortiori catchment-wide protection measures are the main drivers of river ecological water quality. However, distinctive results from the

    Evaporation of soil moisture is one of the most important processes affecting water availability in semiarid ecosystems. Biological soil crusts, which are widely distributed ground cover in these ecosystems, play a recognized role on water processes. Where they roughen surfaces, water residence time and thus infiltration can be greatly enhanced, whereas their ability to clog soil pores or cap the soil surface when wetted can greatly decrease infiltration rate, thus affecting evaporative losses. In this work, we compared evaporation in soils covered by physical crusts, biological crusts in different developmental stages and in the soils underlying the different biological crust types. Our results show that during the time of the highest evaporation (Day 1), there was no difference among any of the crust types or the soils underlying them. On Day 2, when soil moisture was moderately low (11%), evaporation was slightly higher in well-developed biological soil crusts than in physical or poorly developed biological soil crusts. However, crust removal did not cause significant changes in evaporation compared with the respective soil crust type. These results suggest that the small differences we observed in evaporation among crust types could be caused by differences in the properties of the soil underneath the biological crusts. At low soil moisture (evaporation among crust types or the underlying soils. Water loss for the complete evaporative cycle (from saturation to dry soil) was similar in both crusted and scraped soils. Therefore, we conclude that for the specific crust and soil types tested, the presence or the type of biological soil crust did not greatly modify evaporation with respect to physical crusts or scraped soils.

  9. Is ground cover vegetation an effective biological control enhancement strategy against olive pests?

    Directory of Open Access Journals (Sweden)

    Daniel Paredes

    Full Text Available Ground cover vegetation is often added or allowed to generate to promote conservation biological control, especially in perennial crops. Nevertheless, there is inconsistent evidence of its effectiveness, with studies reporting positive, nil or negative effects on pest control. This might arise from differences between studies at the local scale (e.g. orchard management and land use history, the landscape context (e.g. presence of patches of natural or semi-natural vegetation near the focal orchard, or regional factors, particularly climate in the year of the study. Here we present the findings from a long-term regional monitoring program conducted on four pest species (Bactrocera oleae, Prays oleae, Euphyllura olivina, Saissetia oleae in 2,528 olive groves in Andalusia (Spain from 2006 to 2012. Generalized linear mixed effect models were used to analyze the effect of ground cover on different response variables related to pest abundance, while accounting for variability at the local, landscape and regional scales. There were small and inconsistent effects of ground cover on the abundance of pests whilst local, landscape and regional variability explained a large proportion of the variability in pest response variables. This highlights the importance of local and landscape-related variables in biological control and the potential effects that might emerge from their interaction with practices, such as groundcover vegetation, implemented to promote natural enemy activity. The study points to perennial vegetation close to the focal crop as a promising alternative strategy for conservation biological control that should receive more attention.

To fill this gap, this work was aimed to determine the effects of leguminous cover crops on the chemical and biological properties of the soil and on the structure of the microbial community in pots of Citrus unshiu (Marcovitch. After amendment with cover crops, an increase in total organic C (TOC, total extractable C (TEC, and total N (TN contents were observed irrespective of the type of soil. Substrate induced respiration (SIR, and potentially mineralisable nitrogen (PMN, tested three times in one year, were higher in soils with leguminous cover crops while no significant differences were observed in protease and deaminase activity. The effect on the chemical and biochemical properties of the soil was more evident in plots containing Trifolium subterraneum. No changes were observed in the microbial communities studied (_-proteobacteria, _-proteobacteria, nitrogen-fixing, and ammonia oxidizers irrespective of the kind of cover crop or type of soil, neither were variations noted during the trial.

  13. Diel hysteresis between soil respiration and soil temperature in a biological soil crust covered desert ecosystem.

    Soil respiration induced by biological soil crusts (BSCs) is an important process in the carbon (C) cycle in arid and semi-arid ecosystems, where vascular plants are restricted by the harsh environment, particularly the limited soil moisture. However, the interaction between temperature and soil respiration remains uncertain because of the number of factors that control soil respiration, including temperature and soil moisture, especially in BSC-dominated areas. In this study, the soil respiration in moss-dominated crusts and lichen-dominated crusts was continuously measured using an automated soil respiration system over a one-year period from November 2015 to October 2016 in the Shapotou region of the Tengger Desert, northern China. The results indicated that over daily cycles, the half-hourly soil respiration rates in both types of BSC-covered areas were commonly related to the soil temperature. The observed diel hysteresis between the half-hourly soil respiration rates and soil temperature in the BSC-covered areas was limited by nonlinearity loops with semielliptical shapes, and soil temperature often peaked later than the half-hourly soil respiration rates in the BSC-covered areas. The average lag times between the half-hourly soil respiration rates and soil temperature for both types of BSC-covered areas were two hours over the diel cycles, and they were negatively and linearly related to the volumetric soil water content. Our results highlight the diel hysteresis phenomenon that occurs between soil respiration rates and soil temperatures in BSC-covered areas and the negative response of this phenomenon to soil moisture, which may influence total C budget evaluations. Therefore, the interactive effects of soil temperature and moisture on soil respiration in BSC-covered areas should be considered in global carbon cycle models of desert ecosystems.

    2014-12-01

    Full Text Available In this paper we present a strategy for analyzing the text of the textbook based on principles of Actor-Network Theory. This theory seeks to understand central claims about knowledge, subjectivity, society and nature, as effects of an interaction network. By analyzing the argumentative strategies employed by the authors of the text analyzed, we found that there is a process of strengthening the scientific explanation that construct a conception of science and which leaves religious conceptions isolated. In this process, the authors establish a network that exclude religious explanation of the field of rationality and interdict the rationality of religion. We wondered whether this is the best attitude when considering the diversity present in school.

  15. Frequent fire promotes diversity and cover of biological soil crusts in a derived temperate grassland.

    The intermediate disturbance hypothesis (IDH) predicts that species diversity is maximized at moderate disturbance levels. This model is often applied to grassy ecosystems, where disturbance can be important for maintaining vascular plant composition and diversity. However, effects of disturbance type and frequency on cover and diversity of non-vascular plants comprising biological soil crusts are poorly known, despite their potentially important role in ecosystem function. We established replicated disturbance regimes of different type (fire vs. mowing) and frequency (2, 4, 8 yearly and unburnt) in a high-quality, representative Themeda australis-Poa sieberiana derived grassland in south-eastern Australia. Effects on soil crust bryophytes and lichens (hereafter cryptogams) were measured after 12 years. Consistent with expectations under IDH, cryptogam richness and abundance declined under no disturbance, likely due to competitive exclusion by vascular plants as well as high soil turnover by soil invertebrates beneath thick grass. Disturbance type was also significant, with burning enhancing richness and abundance more than mowing. Contrary to expectations, however, cryptogam richness increased most dramatically under our most frequent and recent (2 year) burning regime, even when changes in abundance were accounted for by rarefaction analysis. Thus, from the perspective of cryptogams, 2-year burning was not an adequately severe disturbance regime to reduce diversity, highlighting the difficulty associated with expression of disturbance gradients in the application of IDH. Indeed, significant correlations with grassland structure suggest that cryptogam abundance and diversity in this relatively mesic (600 mm annual rainfall) grassland is maximised by frequent fires that reduce vegetation and litter cover, providing light, open areas and stable soil surfaces for colonisation. This contrasts with detrimental effects of 2-year burning on native perennial grasses

    Biological soil crust communities provide important ecosystem services to arid lands, particularly regarding soil fertility and stability against erosion. In North America, and in many other areas of the globe, increasingly intense human activities, ranging from cattle grazing to military training, have resulted in the significant deterioration of biological soil surface cover of soils. With the intent of attaining sustainable land use practices, we are conducting a 5-year, multi-institutional research effort to develop feasible soil crusts restoration strategies for US military lands. We are including field sites of varying climatic regions (warm and cold deserts, in the Chihuahuan Desert and in the Great Basin, respectively) and varying edaphic characteristics (sandy and silty soils in each). We have multiple aims. First, we aim to establishing effective "biocrust nurseries" that produce viable and pedigreed inoculum, as a supply center for biocrust restoration and for research and development. Second, we aim to develop optimal field application methods of biocrust inoculum in a series of field trials. Currently in our second year of research, we will be reporting on significant advances made on optimizing methodologies for the large-scale supply of inoculum based on a) pedigreed laboratory cultures that match the microbial community structure of the original sites, and b) "in soil" biomass enhancement, whereby small amounts of local crusts are nursed under greenhouse conditions to yield hundred-fold increases in biomass without altering significantly community structure. We will also report on field trials for methodologies in field application, which included shading, watering, application of chemical polymers, and soil surface roughening. In a soon-to-be-initiated effort we also aim to evaluate soil and plant responses to biocrust restoration with respect to plant community structure, soil fertility, and soil stability, in multi-factorial field experiments.

    Dissipative Kerr solitons (DKS) in optical microresonators provide a highly miniaturised, chip-integrated frequency comb source with unprecedentedly high repetition rates and spectral bandwidth. To date, such frequency comb sources have been successfully applied in the optical telecommunication band for dual-comb spectroscopy, coherent telecommunications, counting of optical frequencies and distance measurements. Yet, the range of applications could be significantly extended by operating in the near-infrared spectral domain, which is a prerequisite for biomedical and Raman imaging applications, and hosts commonly used optical atomic transitions. Here we show the operation of photonic-chip-based soliton Kerr combs driven with 1 micron laser light. By engineering the dispersion properties of a Si 3 N 4 microring resonator, octave-spanning soliton Kerr combs extending to 776 nm are attained, thereby covering the optical biological imaging window. Moreover, we show that soliton states can be generated in normal group-velocity dispersion regions when exploiting mode hybridisation with other mode families.

To determine the frequency with which topics in leading online evidence-based medical textbooks report treatment recommendations consistent with more recently published research evidence. Summarized treatment recommendations in 200 clinical topics (ie, disease states) covered in four evidence-based textbooks--UpToDate, Physicians' Information Education Resource (PIER), DynaMed, and Best Practice--were compared with articles identified in an evidence rating service (McMaster Premium Literature Service, PLUS) since the date of the most recent topic updates in each textbook. Textbook treatment recommendations were compared with article results to determine if the articles provided different, new conclusions. From these findings, the proportion of topics which potentially require updating in each textbook was calculated. 478 clinical topics were assessed for inclusion to find 200 topics that were addressed by all four textbooks. The proportion of topics for which there was 1 or more recently published articles found in PLUS with evidence that differed from the textbooks' treatment recommendations was 23% (95% CI 17-29%) for DynaMed, 52% (95% CI 45-59%) for UpToDate, 55% (95% CI 48-61%) for PIER, and 60% (95% CI 53-66%) for Best Practice (χ(2) (3)=65.3, P<.001). The time since the last update for each textbook averaged from 170 days (range 131-209) for DynaMed, to 488 days (range 423-554) for PIER (P<.001 across all textbooks). In online evidence-based textbooks, the proportion of topics with potentially outdated treatment recommendations varies substantially.

    2013-12-01

    Full Text Available The use of cover crops has been suggested as an effective method to maintain and/or increase the organic matter content, while maintaining and/or enhancing the soil physical, chemical and biological properties. The fertility of Cerrado soils is low and, consequently, phosphorus levels as well. Phosphorus is required at every metabolic stage of the plant, as it plays a role in the processes of protein and energy synthesis and influences the photosynthetic process. This study evaluated the influence of cover crops and phosphorus rates on soil chemical and biological properties after two consecutive years of common bean. The study analyzed an Oxisol in Selvíria (Mato Grosso do Sul, Brazil, in a randomized block, split plot design, in a total of 24 treatments with three replications. The plot treatments consisted of cover crops (millet, pigeon pea, crotalaria, velvet bean, millet + pigeon pea, millet + crotalaria, and millet + velvet bean and one plot was left fallow. The subplots were represented by phosphorus rates applied as monoammonium phosphate (0, 60 and 90 kg ha-1 P2O5. In August 2011, the soil chemical properties were evaluated (pH, organic matter, phosphorus, potential acidity, cation exchange capacity, and base saturation as well as biological variables (carbon of released CO2, microbial carbon, metabolic quotient and microbial quotient. After two years of cover crops in rotation with common bean, the cover crop biomass had not altered the soil chemical properties and barely influenced the microbial activity. The biomass production of millet and crotalaria (monoculture or intercropped was highest. The biological variables were sensitive and responded to increasing phosphorus rates with increases in microbial carbon and reduction of the metabolic quotient.

    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.

    Full Text Available Pesquisas têm demonstrado que o livro didático tem papel determinante na organização curricular e na prática pedagógica dos professores. O livro didático precisa, como sugerem os Parâmetros Curriculares Nacionais do Ensino Médio (PCNEM, contemplar conhecimentos modernos em um contexto de historicidade, discutindo, paralelamente, temas de apelo social. Esta pesquisa analisou os livros didáticos de acordo com o padrão de atualização, utilizando a Biologia como modelo. Os resultados sugerem que os atuais livros didáticos não estão atualizados no estudo dos temas considerados essenciais para perfeito entendimento e aquisição de informações associadas ao rápido avanço do conhecimento na área da Nova Biologia. Aponta-se para o fato de que necessitam de reformulação e atualizações com textos modernos, que promovam mudanças conceituais.Recent research has demonstrated that Science textbooks have a determining role in curricular organization and that teachers use them to compose their classes, activities, and exams. The National Programs for High School Curriculum Parameters (PCNEM has infuenced Brazilian education since 1999, bringing updated concepts of Biology and genetics, including themes such as transgenics, gene therapy, cloning, stem cell and paternity testing into the curriculum. The teaching of High School is challenging because of the need to contemplate both classic and modern knowledge within a historical context that simultaneously discusses appealing social themes. The current study analyzed how up-to-date the current High School textbooks are, using the Biology as a model. The themes included in the so-called New Biology was analyzed because they are essential to a good understanding of modern concepts of great social significance. The results suggest that the current textbooks are not up-to-date concerning the themes considered essential for perfect understanding and acquisition of suitable information which

    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.

  15. Biological Oceanography

    Science.gov (United States)

    Dyhrman, Sonya

    2004-10-01

    The ocean is arguably the largest habitat on the planet, and it houses an astounding array of life, from microbes to whales. As a testament to this diversity and its importance, the discipline of biological oceanography spans studies of all levels of biological organization, from that of single genes, to organisms, to their population dynamics. Biological oceanography also includes studies on how organisms interact with, and contribute to, essential global processes. Students of biological oceanography are often as comfortable looking at satellite images as they are electron micrographs. This diversity of perspective begins the textbook Biological Oceanography, with cover graphics including a Coastal Zone Color Scanner image representing chlorophyll concentration, an electron micrograph of a dinoflagellate, and a photograph of a copepod. These images instantly capture the reader's attention and illustrate some of the different scales on which budding oceanographers are required to think. Having taught a core graduate course in biological oceanography for many years, Charlie Miller has used his lecture notes as the genesis for this book. The text covers the subject of biological oceanography in a manner that is targeted to introductory graduate students, but it would also be appropriate for advanced undergraduates.

    Energy Technology Data Exchange (ETDEWEB)

    Pearsall, D.R.

    1995-12-31

    The aim of this research is to provide an understanding of the three-dimensional (air-earth-organism) units of the landscape of the University of Michigan Biological Station (UMBS) that the author calls landscape ecosystem types, or simply ecosystems. Specifically, he has focused on the kinds, spatial location and patterns, and composition (physiography, soil, vegetation) of the local landscape ecosystem types of UMBS and Colonial Point. Future research on the functioning of these ecosystems together with inventories of their plant and animal life will add significantly to the landscape ecology research that has been initiated. A major reason for this research is to provide the conceptual basis and baseline data for understanding ecosystem change. Although it is popular to speak of climate change, entire ecosystems change; some components change faster than others.

    2014-01-01

    Full Text Available In the present research, it will be shown how grammar activities in textbooks still retain the structural method of teaching grammar. The results found by previous scholars’ research will be covered, and illustrated by excerpts of textbooks, including comparison of Hong Kong and Malaysian textbooks. Communicative Language Teaching (CLT materialized in the West in the 1960s, and has extended to the Eastern countries over the last 20 years (Chung, 2005: 33. Since the introduction of CLT, many English textbooks have been published to incorporate communicative activities, authentic material and personalized contexts, however, most of the learning and teaching of grammar in textbooks do not fully reflect CLT principles (ibid.. The paper is written to show concerns over textbook designing issues and hence provide recommendations in changing the design of the modern English language textbooks. In the end of the paper, this research will suggest methods of designing more communicative grammar activities in English language textbooks for future textbook designers having guidelines in compiling the CLT English language textbooks. Besides, some approaches of communicative teaching with the CLT textbooks will be recommended to the pre- and in-service English language teachers in order to lead them to the current trend of CLT.

    Directory of Open Access Journals (Sweden)

    H. T. Root

    2017-09-01

    Full Text Available Changing fire regimes in western North America may impact biological soil crust (BSC communities that influence many ecosystem functions, such as soil stability and C and N cycling. However, longer-term effects of wildfire on BSC abundance, species richness, functional groups, and ecosystem functions after wildfire (i.e., BSC resilience are still poorly understood. We sampled BSC lichen and bryophyte communities at four sites in Idaho, USA, within foothill steppe communities that included wildfires from 12 to 16 years old. We established six plots outside each burn perimeter and compared them with six plots of varying severity within each fire perimeter at each site. BSC cover was most strongly negatively impacted by wildfire at sites that had well-developed BSC communities in adjacent unburned plots. BSC species richness was estimated to be 65 % greater in unburned plots compared with burned plots, and fire effects did not vary among sites. In contrast, there was no evidence that vascular plant functional groups or fire severity (as measured by satellite metrics differenced normalized burn ratio (dNBR or relativized differenced normalized burn ratio (RdNBR significantly affected longer-term BSC responses. Three large-statured BSC functional groups that may be important in controlling wind and water erosion (squamulose lichens, vagrant lichens, and tall turf mosses exhibited a significant decrease in abundance in burned areas relative to adjacent unburned areas. The decreases in BSC cover and richness along with decreased abundance of several functional groups suggest that wildfire can negatively impact ecosystem function in these semiarid ecosystems for at least 1 to 2 decades. This is a concern given that increased fire frequency is predicted for the region due to exotic grass invasion and climate change.

    Full Text Available In Slovenia, the migrations are treated in almost all geographical textbooks for different levels of education. 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.

    1996-01-01

    Since the injective envelope and projective cover were defined by Eckmann and Bas in the 1960s, they have had great influence on the development of homological algebra, ring theory and module theory. In the 1980s, Enochs introduced the flat cover and conjectured that every module has such a cover over any ring. This book provides the uniform methods and systematic treatment to study general envelopes and covers with the emphasis on the existence of flat cover. It shows that Enochs' conjecture is true for a large variety of interesting rings, and then presents the applications of the results. Readers with reasonable knowledge in rings and modules will not have difficulty in reading this book. It is suitable as a reference book and textbook for researchers and graduate students who have an interest in this field.

    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

  9. Understanding European education landscape on natural disasters - a textbook research

    2012-04-01

    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

    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.

  12. Towards a Framework of Socio-Linguistic Analysis of Science Textbooks: The Greek Case

    Science.gov (United States)

    Dimopoulos, Kostas; Koulaidis, Vasilis; Sklaveniti, Spyridoula

    2005-09-01

    This study aims at presenting a grid for analysing the way the language employed in Greek school science textbooks tends to project pedagogic messages. These messages are analysed for the different school science subjects (i.e., Physics, Chemistry, Biology) and educational levels (i.e., primary and lower secondary level). The analysis is made using the dimensions of content specialisation (classification) and social-pedagogic relationships (framing) promoted by the language of the school science textbooks as well as the elaboration and abstraction of the corresponding linguistic code (formality), thus combining pedagogical and socio-linguistic perspectives. Classification and formality are used to identify the ways science textbooks tend to position students in relation to the interior of the corresponding specialised body of knowledge (i.e., in terms of content and code) while framing is used to identify the ways science textbooks tend to position students as learning subjects within the school science discourse. The results show that the kind of pedagogic messages projected by the textbooks depends mainly on the educational level and not particularly on the specific discipline. As the educational level rises a gradual move towards more specialised forms of scientific knowledge (mainly in terms of code) with a parallel increase in the students' autonomy in accessing the textbook material is noticed. The implications concern the way both students and teachers approach science textbooks as well as the roles they can undertake by internalising the textbooks' pedagogic messages and also the way science textbooks are authored.

  17. Preliminary assessment of geologic materials to minimize biological intrusion of low-level waste trench covers and plans for the future

    International Nuclear Information System (INIS)

    Hakonson, T.E.; White, G.C.; Gladney, E.S.; Muller, M.

    1981-01-01

    The long-term integrity of low-level waste shallow land burial sites is dependent on the interaction of physical, chemical, and biological factors that modify the waste containment system. Past research on low-level waste shallow land burial methods has emphasized physical (i.e., water infiltration, soil erosion) and chemical (radionuclide leaching) processes that can cause radionuclide transport from a waste site. Preliminary results demonstrate that a sandy backfill material offers little resistance to root and animal intrusion through the cover profile. However, bentonite clay, cobble, and cobble-gravel combinations do reduce plant root and animal intrusion through cover profiles compared with sandy backfill soil. However, bentonite clay barrier systems appear to be degraded by plant roots through time. Desiccation of the clay barrier by invading plant roots may limit the usefulness of bentonite clay as a moisture and/or biological carrier unless due consideration is given to this interaction. Future experiments are described that further examine the effect of plant roots on clay barrier systems and that determine the effectiveness of proposed biological barriers on larger scales and under various stress conditions

    2016-12-01

    The offshore extent of seagrass habitat along the West Florida (USA) coast represents an important corridor for inshore-offshore migration of economically important fish and shellfish. Surviving at the fringe of light requirements, offshore seagrass beds are sensitive to changes in water clarity. Beyond and intermingled with the offshore seagrass areas are large swaths of colonized hard bottom. These offshore habitats of the West Florida coast have lacked mapping efforts needed for status and trends monitoring. The objective of this study was to propose an object-based classification method for mapping offshore habitats and to compare results to traditional photo-interpreted maps. Benthic maps depicting the spatial distribution and percent biological cover were created from WorldView-2 satellite imagery using Object Based Image Analysis (OBIA) method and a visual photo-interpretation method. A logistic regression analysis identified depth and distance from shore as significant parameters for discriminating spectrally similar seagrass and colonized hard bottom features. Seagrass, colonized hard bottom and unconsolidated sediment (sand) were mapped with 78% overall accuracy using the OBIA method compared to 71% overall accuracy using the photo-interpretation method. This study presents an alternative for mapping deeper, offshore habitats capable of producing higher thematic (percent biological cover) and spatial resolution maps compared to those created with the traditional photo-interpretation method.

    2016-04-01

    How soil cover types and extreme rainfall event influence carbon (C) release in temperate desert ecosystems has largely been unexplored. We assessed the effects of extreme rainfall (quantity and intensity) events on the carbon release from soils covered by different types of biological soil crusts (BSCs) in fixed sand dunes in the Tengger Desert, Shapotou regionof northern China. We removed intact crusts down to 10 cm and measured them in PVC mesocosms. A Li-6400-09 Soil Chamber was used to measure the respiration rates of the BSCs immediately after the rainfall stopped, and continued until the respiration rates of the BSCs returned to the pre-rainfall basal rate. Our results showed that almost immediately after extreme rainfall events the respiration rates of algae crust and mixed crust were significantly inhibited, but moss crust was not significantly affected. The respiration rates of algae crust, mixed crust, and moss crust in extreme rainfall quantity and intensity events were, respectively, 0.12 and 0.41 μmolCO2/(m2•s), 0.10 and 0.45 μmolCO2/(m2•s), 0.83 and 1.69 μmolCO2/(m2•s). Our study indicated that moss crust in the advanced succession stage can well adapt to extreme rainfall events in the short term.

    Directory of Open Access Journals (Sweden)

    Lazarević Emilija

    2009-01-01

    Full Text Available Hermetic textbook language poses a significant problem in education of the young in our country. The goal of this paper is to point out to the complexity of vocabulary in textbooks, which contributes to students' lack of understanding of what they are reading. Since we established that textbooks in narrative subjects - history, geography and biology - are mostly used during studying and that students mark them as especially difficult for understanding, the subject of this research is precisely the analysis of words which seventh-grade students from primary school state as unfamiliar on a randomly selected, but balanced in terms of length, textbook text of those subjects. The results of frequency analysis indicate that there are a lot of unfamiliar expert words, and frequently the same number, or even more, of common Serbian words in textbook texts, especially in history. Approximately the same or even larger number of unfamiliar words occurs in familiar texts when compared to unfamiliar, which indicates that the previous usage of texts does not contribute to their understanding. Based on correlation analysis referring to the number of unfamiliar words, frequency of textbook usage, perception of difficulty of the text in textbook, general and the achievement in the particular subject, it was determined that unfamiliar words are not only mentioned by students with low grades, although they do it more often, nor that only these students are the ones complaining how difficult textbooks are to them. Based on regression analysis, the number of unfamiliar words, especially in the history textbook, even figures as a predictor of success, which seems contradictory and can be interpreted differently. The results point out to the fact that inaccessibility of textbook language mostly does not guide the students to learn new words, but causes revolt and thus disables the development of language, scientific concepts and acquiring professional terminology

    reorganization of the publishing company, web based user interfaces, and ultimately the branding, that market these new digital objects, are building powerful discourses around the product. Thus it is suggested that the design process of the iBog-case can be understood in a model of database-based publishing......Building on a preliminary case study of the Danish educational publisher, Systime A/S, and its flagship product, the web based ‘iBog’ {Systime 2014}, this paper explores how digital textbooks can be understood as design. The shaping of digital books is seen as intertwined in a wider circuit...... with multiple levels. In the final analysis, the iBog is much more than a product and a technology. It is a brand that goes beyond what can be studied by looking at the digital textbook as a singular artefact....

Therefore, teaching has to beaccompanied by clear explanations and by simulations illustrating theexamined topics. This is why an electronic textbook (ET of EM wavesand applications was developed. The ET presents theoreticaldescriptions of selected EM phenomena on two levels - on a bachelor'sone and a master's one. Descriptive parts of the ET are completed bycomputer programs, which enable the reader to simulate the studiedphenomena. Moreover, the ET explains the practical implementation ofsimulation routines in MATLAB, which helps students to understand arelationship between rather complicated mathematics and a relativelysimple source code of its software implementation. Since the ET isfreely accessible on the web, students can use it whenever as aclassical textbook, a handbook or a software package.

    Belnap, Jayne; Phillips, Susan L.; Smith, Stanley D.

    2007-01-01

    Biological soil crusts are an integral part of dryland ecosystems. We monitored the cover of lichens and mosses, cyanobacterial biomass, concentrations of UV-protective pigments in both free-living and lichenized cyanobacteria, and quantum yield in the soil lichen species Collema in an undisturbed Mojave Desert shrubland. During our sampling time, the site received historically high and low levels of precipitation, whereas temperatures were close to normal. Lichen cover, dominated by Collema tenax and C. coccophorum, and moss cover, dominated by Syntrichia caninervis, responded to both increases and decreases in precipitation. This finding for Collema spp. at a hot Mojave Desert site is in contrast to a similar study conducted at a cool desert site on the Colorado Plateau in SE Utah, USA, where Collema spp. cover dropped in response to elevated temperatures, but did not respond to changes in rainfall. The concentrations of UV-protective pigments in free-living cyanobacteria at the Mojave Desert site were also strongly and positively related to rainfall received between sampling times (R2 values ranged from 0.78 to 0.99). However, pigment levels in the lichenized cyanobacteria showed little correlation with rainfall. Quantum yield in Collema spp. was closely correlated with rainfall. Climate models in this region predict a 3.5–4.0 °C rise in temperature and a 15–20% decline in winter precipitation by 2099. Based on our data, this rise in temperature is unlikely to have a strong effect on the dominant species of the soil crusts. However, the predicted drop in precipitation will likely lead to a decrease in soil lichen and moss cover, and high stress or mortality in soil cyanobacteria as levels of UV-protective pigments decline. In addition, surface-disturbing activities (e.g., recreation, military activities, fire) are rapidly increasing in the Mojave Desert, and these disturbances quickly remove soil lichens and mosses. These stresses combined are likely to

  3. A rapid transition from ice covered CO2–rich waters to a biologically mediated CO2 sink in the eastern Weddell Gyre

    W. Geibert

    2008-09-01

    Full Text Available Circumpolar Deep Water (CDW, locally called Warm Deep Water (WDW, enters the Weddell Gyre in the southeast, roughly at 25° E to 30° E. In December 2002 and January 2003 we studied the effect of entrainment of WDW on the fugacity of carbon dioxide (fCO2 and dissolved inorganic carbon (DIC in Weddell Sea surface waters. Ultimately the fCO2 difference across the sea surface drives air-sea fluxes of CO2. Deep CTD sections and surface transects of fCO2 were made along the Prime Meridian, a northwest-southeast section, and along 17° E to 23° E during cruise ANT XX/2 on FS Polarstern. Upward movement and entrainment of WDW into the winter mixed layer had significantly increased DIC and fCO2 below the sea ice along 0° W and 17° E to 23° E, notably in the southern Weddell Gyre. Nonetheless, the ice cover largely prevented outgassing of CO2 to the atmosphere. During and upon melting of the ice, biological activity rapidly reduced surface water fCO2 by up to 100 μatm, thus creating a sink for atmospheric CO2. Despite the tendency of the surfacing WDW to cause CO2 supersaturation, the Weddell Gyre may well be a CO2 sink on an annual basis due to this effective mechanism involving ice cover and ensuing biological fCO2 reduction. Dissolution of calcium carbonate (CaCO3 in melting sea ice may play a minor role in this rapid reduction of surface water fCO2.

  4. Teaching NMR Using Online Textbooks

    1999-12-01

    Full Text Available Nuclear magnetic resonance (NMR spectroscopy has almost become an essential analytical tool for the chemist. High-resolution one- and multi-dimensional NMR, timedomain NMR, and NMR microscopy are but a few of the NMR techniques at a chemist's disposal to determine chemical structure and dynamics. Consequently, even small chemistry departments are finding it necessary to provide students with NMR training and experience in at least some of these techniques. The hands-on experience is readily provided with access to state-of-the-art commercial spectrometers. Instruction in the principles of NMR is more difficult to achieve as most instructors try to teach NMR using single organic or analytical chemistry book chapters with static figures. This paper describes an online textbook on NMR spectroscopy called The Basics of NMR (http://www.cis.rit.edu/htbooks/nmr/ suitable for use in teaching the principles of NMR spectroscopy. The book utilizes hypertext and animations to present the principles of NMR spectroscopy. The book can be used as a textbook associated with a lecture or as a stand-alone teaching tool. Conference participants are encouraged to review the textbook and evaluate its suitability for us in teaching NMR spectroscopy to undergraduate chemistry majors.

    2008-10-01

    The majority of "special access" students at the University of Cape Town are second language English speakers for whom reading the physics textbook is daunting. As a strategy to encourage meaningful engagement with the text, students wrote textbook summaries due the day material was covered in class. The summaries were returned, and they could bring them or re-write them for use during their examinations. A framework was developed to analyze the summaries based on Waywood, defining three cognitive levels seen in mathematics journaling: recounting, summarizing, and dialoging. This framework was refined, expanded, and tested. Interviews with students were conducted for their views on summary writing and survey questions were included on their final exams. The study was carried out in the 2007 spring semester of the "Foundation Physics Course," a component of the special access program.

    2012-05-01

    To engage students in a more meaningful discussion of course material and prompt their higher thinking skills, most instructors expect students to read the course textbook for initial exposure to the course content before class. However, as many instructors are aware, most students do not read their textbook throughout the quarter.1,2 At California State Polytechnic University, Pomona (Cal Poly Pomona) we have adopted web-based multimedia learning modules (MLMs) as prelecture assignments to help students to prepare for the class activities. The MLMs place lecture contents into the hands and control of the learners; similar to "flipped"3 or "inverted"4 classroom approaches, this method allows students to receive key course content outside of class and apply and analyze the content actively during class. In addition to initial exposure to basic principle, the MLMs provide additional worked examples that cannot be thoroughly covered in class.

    Full Text Available Abstract Background Physicians caring for elderly people encounter death and dying more frequently than their colleagues in most other disciplines. Therefore we sought to examine the end-of-life content in popular geriatric textbooks and determine their usefulness in helping geriatricians manage patients at the end of their lives. Methods Five popular geriatric textbooks were chosen. Chapters on Alzheimer's disease, stroke, chronic heart failure, chronic obstructive pulmonary disease and lung cancer were examined because of their high mortality rates among the elderly patients. Text relevant to end-of-life care was highlighted. Two reviewers independently coded text into 10 pre specified domains and rated them for the presence of end-of-life information. Content was rated as absent, minimally helpful, or helpful. The proportion of helpful information was calculated. Results The textbook with the best end-of-life coverage contained 38% helpful information, the worst had only 15% helpful information. Minimally helpful information ranged from 24% to 50%. As much as 61% of the content in one textbook contained no helpful information at all. Of the ten domains, epidemiology, disease progression and prognostic factors were fairly well covered. Information on advance care planning, ethical issues, decision making and effects of death and dying on patient's family were generally lacking under the individual diseases though they were covered as general topics in other parts of the textbooks. All except one textbook dedicated a chapter to the care of the dying. Conclusion This study showed that end-of-life content in geriatric textbooks differed significantly. Most of the textbooks lack good coverage on end-of-life care and more can be done to improve on this.

    en el que se evaluaron, de modo estructurado, todos los libros de biología recomendados para la secundaria por el Ministerio de la Educación. El análisis de cada libro se realizó según su contenido de nutrición a partir de una ficha de evaluación. Las variables evaluadas fueron seleccionadas mediante revisión de literatura, y se pudo clasificarlas en: Suficiente: cuando las variables analizadas estuvieran totalmente presentes en los libros didácticos y en concordancia con los conocimientos actuales; Insuficiente: cuando las variables analizadas estuvieran parcialmente presentes en los libros didácticos, en concordancia con los conocimientos actuales; Ausente: cuando el contenido no fuera abordado en el libro didáctico. Variables presentes, pero desactualizadas o incorrectas, fueron analizadas individualmente y de modo descriptivo. La técnica de «análisis de contenido» guió a ese trabajo. RESULTADOS: Todos los libros didácticos contenían informaciones sobre nutrición, pero, en su mayoría, se presentaban insuficientes para promover elecciones alimentarias conscientes y/o cambios de hábitos. Algunas informaciones estaban ausentes en algunos libros, como: hipovitaminose A y deficiencia de folato (100%, anemia ferropénica (89%, obesidad, deficiencia de iodo y pirámide de los alimentos (78%. CONCLUSIONES: La inserción de la educación nutricional en el currículum escolar y la revisión periódica para adecuación de los contenidos sobre nutrición en los libros didácticos son medidas coadyuvantes a la prevención de agravio a la salud de los futuros adultos.OBJECTIVE:To analyze the nutrition-related issues of high school Biology textbooks by comparing the available information with the current knowledge.

    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.

    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.

  4. Climatic, biological, and land cover controls on the exchange of gas-phase semivolatile chemical pollutants between forest canopies and the atmosphere.

    Science.gov (United States)

    Nizzetto, Luca; Perlinger, Judith A

    2012-03-06

    An ecophysiological model of a structured broadleaved forest canopy was coupled to a chemical fate model of the air-canopy exchange of gaseous semivolatile chemicals to dynamically assess the short-term (hours) and medium term (days to season) air-canopy exchange and the influence of biological, climatic, and land cover drivers on the dynamics of the air-canopy exchange and on the canopy storage for airborne semivolatile pollutants. The chemical fate model accounts for effects of short-term variations in air temperature, wind speed, stomatal opening, and leaf energy balance, all as a function of layer in the canopy. Simulations showed the potential occurrence of intense short/medium term re-emission of pollutants having log K(OA) up to 10.7 from the canopy as a result of environmental forcing. In addition, relatively small interannual variations in seasonally averaged air temperature, canopy biomass, and precipitation can produce relevant changes in the canopy storage capacity for the chemicals. It was estimated that possible climate change related variability in environmental parameters (e.g., an increase of 2 °C in seasonally averaged air temperature in combination with a 10% reduction in canopy biomass due to, e.g., disturbance or acclimatization) may cause a reduction in canopy storage capacity of up to 15-25%, favoring re-emission and potential for long-range atmospheric transport. On the other hand, an increase of 300% in yearly precipitation can increase canopy sequestration by 2-7% for the less hydrophobic compounds.

    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.

    Full Text Available Research collected and reviewed a number of empirical studies in the field of educational research regarding the analysis of mathematics textbooks to provide summary and overview the information there in. The questions were identified via Google Scholar and collected from different data sources. A total of 44 papers published from 1953 to 2015 were selected based specific criteria, with 24 articles include in the SSCI database. Descriptive statistics were used to evaluate and interpret the results. A perspective on the learning analysis methods was used to collect studies and showed the mathematics textbooks analyzed were investigated under four themes: The analysis of standards, distributive property, language in mathematics, and others. School’s level which is investigated textbooks: Kindergarten, elementary, junior school, and senior school. Subjects covered in the mathematics textbooks included algebra and arithmetic, geometry, measurement, data analysis and probability, number and operations, among others. Research found the most frequently discussed in perspective on learning was the analysis of the standards and the distributive property (15 studies, the most common subject was number and operations (16 studies, and the highest number in school’s level was elementary school (18 studies. Nevertheless, fewer studies have been found to analyzing mathematics textbooks. Future research can pay attention for the relevant theoretical issues and collaborate studies in more perspective learning analysis.

    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.

    2017-06-01

    Full Text Available Some significant components are essential in teaching a language. Among these, textbooks are the most significant ones and must be considered seriously. Textbooks play an important role in EFL teaching and learning because they can provide ready-made materials to both teachers and students. Besides, if textbooks aren’t used appropriately, they may spoil the process of teaching. This study aimed at analyzing listening and speaking activities of the textbook Prospect 3 which is used for Junior High School third graders in order to investigate in which level of lower or higher of the learning objectives related to Bloom’s (2001 Revised Taxonomy of Cognitive Domain they would be classified. The findings revealed that all of the activities of listening and speaking skills were classified as the low level of cognitive complexity and could not train the students of this grade for high levels of learning objectives. Hence the teachers should employ extra activities to make the students perform in higher levels of thinking skills and book designers should improve the content of the textbook to cover the higher levels of the cognitive domain.

  16. The Concept of the Interculture in Time: (Intercultural Topics in Textbooks of French as a Foreign Language

    Directory of Open Access Journals (Sweden)

    Meta Lah

    2012-12-01

    Full Text Available The article deals with the concept of interculturality as used in foreign language didactics. In accordance with the definition of interculturality given in the first part of the article, two categories are included in the analysis – two “levels” of culture, each of them bearing a different name in literature, namely high and popular culture. Various textbooks used for teaching French as a foreign language in Slovenia in both the past and present were chosen for the analysis of topics that cover a fairly long period of time – among them the textbooks by two Slovenian authors: Južnič (1938 and Grad (1954, as well as some generally-used French textbooks, such as Cours de langue et de civilisation françaises (1953, Le nouveau sans frontières (1988 and Nouveau rond point (2011. The article is based on the hypothesis that high culture is more likely to be present in the older textbooks, which are based on traditional methods, whereas in modern textbooks more popular, everyday topics can be found. It is also presumed that topics in modern textbooks are, compared to their more traditional counterparts, introduced in an intercultural manner which could encourage students to compare the culture of the foreign country with their own. Both hypotheses are partly confirmed. In Slovenian textbooks there are very few culture-based topics. On the other hand, they are present in all French textbooks, regardless of the methodology. It is true that Mauger introduces more high culture than the others and that the intercultural topics are presented only in the most recent textbook. In all the others, it is exclusively the culture of the target country that is introduced.

    2013-01-01

    Biology textbooks tend to assert the correctness of evolutionary concepts but mention very little of the evidence that supports them. This gives the impression that evolutionary theory is poorly supported, which discourages acceptance of the theory. A case in point is the age of the Earth. Biology textbooks usually mention that the planet is…

  20. 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.

  1. Comparison of textbook passages, nonfiction trade book passages and fiction trade book passages as instructional tools for learning science

    Science.gov (United States)

    Kelly, Cynthia

    This study examined the impact of different types of text on student achievement in elementary school science. Gender was also examined to see if the type of text passage read had any differential effect on boys' and girls' achievement. This study was a pretest/posttest/retention test design. Eighty-four fourth grade students from a public charter elementary school in South Florida were randomly assigned a passage from a physical science textbook, a physical science nonfiction trade book, a physical science fiction trade book, a biological science textbook or a biological science nonfiction trade book. Results in the physical science content area revealed that students in the textbook passage group had higher posttest and retention test results than students in the nonfiction and fiction trade book passage groups. There was no difference on the posttest results of students in the biological science textbook and nonfiction trade book passage groups. Students in the biological science textbook passage group had higher retention results than students in the biological science nonfiction passage group. Gender results in the physical science content area revealed that boys had a higher retention score than girls in the fiction trade book passage group. There were no gender achievement differences as a result of the text passage read in the biological science content area. It was concluded that no definitive answer as to the efficacy of textbooks versus trade books was possible based upon results of the study. Recommendations for future research include examining the effects of different types of texts in conjunction with other authentic teaching methods.

    Full Text Available The present research aims to investigate the distribution pattern of conjunctions and their ranking in two different corpora, namely the Malaysian school English language Textbook Corpus (Textbook Corpus and the British National Corpus (BNC. An additional objective of the study was to find out how conjunctions had been presented in the Malaysian school English language textbooks (Forms 1-5. The method applied was qualitative content analysis. 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

  20. Robert Heath Lock and his textbook of genetics, 1906.

    Science.gov (United States)

    Edwards, A W F

    2013-07-01

    Robert Heath Lock (1879-1915), a Cambridge botanist associated with William Bateson and R. C. Punnett, published his book Recent Progress in the Study of Variation, Heredity, and Evolution in 1906. This was a remarkable textbook of genetics for one appearing so early in the Mendelian era. It covered not only Mendelism but evolution, natural selection, biometry, mutation, and cytology. It ran to five editions but was, despite its success, largely forgotten following Lock's early death in 1915. Nevertheless it was the book that inspired H. J. Muller to do genetics and was remembered by A. H. Sturtevant as the source of the earliest suggestion that linkage might be related to the exchange of parts between homologous chromosomes. Here we also put forward evidence that it had a major influence on the statistician and geneticist R. A. Fisher at the time he was a mathematics student at Cambridge.

  1. 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.

  2. Biology curriculum in twentieth-century Spain

    Science.gov (United States)

    Barberá, Óscar; Zanón, Beatriz; Pérez-Pl, José Francisco

    1999-01-01

    One hundred years of history of Spanish biology curricula are reviewed in this article. The aim of this analysis is focused on the relationship between socially controversial biological issues and the decisionmaking procedures in the construction of the national curricula published under the different regimes that have governed Spain over the last 100 years. The study covers the secondary level of schooling (age 10 up to university), and is based mainly on the data afforded by the official publications of the nine national curricula in twentieth-century Spain, and some of the main textbooks used for this schooling level. Special attention is given to the teaching of evolution, the most sensitive issue in biology education, and some parallelisms are traced and compared with similar phenomena occurring in other countries. The new trends in biology education from the last reform of the Spanish education system are briefly discussed. This study provides a perspective of the pressures affecting socially controversial issues included in education. These pressures have been identified mainly as political, social, and religious beliefs held by powerful and influential social groups, the same kinds of forces that have existed in other countries worldwide. Studies such as this one, about the real forces that have shaped curriculum development in the past, are vital for understanding the present circumstances in biology education and, therefore, unavoidable in order to enhance future standards in biology education.

  3. 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.

  4. 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.

    Full Text Available Neste artigo, realizo uma leitura do cinema de Rogério Sganzerla, desde o clássico O bandido da luz vermelha até os documentários filmados na década de oitenta, a partir de duas noções centrais: cover e over. Para isso, parto de uma controvérsia com o ensaio de Ismail Xavier, Alegorias do subdesenvolvimento, em que o crítico realiza uma leitura do cinema brasileiro da década de sessenta através do conceito de alegoria; depois releio uma série de textos críticos do próprio Sganzerla, publicados em Edifício Sganzerla, procurando repensar as ideias de “herói vazio” ou “cinema impuro” e sugerindo assim uma nova relação do seu cinema com o tempo e a representação; então busco articular tais ideias com certos procedimentos de vanguarda, como a falsificação, a cópia, o clichê e a colagem; e finalmente procuro mostrar que, no cinema de Sganzerla, a partir principalmente de suas reflexões sobre Orson Welles, a voz é usada de maneira a deformar a interpretação naturalista.

    DEFF Research Database (Denmark)

    Hald, Tine; Baggesen, Dorte Lau

    A risk ranking process identified Toxoplasma gondii and pathogenic verocytotoxin-producing Escherichia coli (VTEC) as the most relevant biological hazards for meat inspection of sheep and goats. As these are not detected by traditional meat inspection, a meat safety assurance system using risk......-based interventions was proposed. Further studies are required on T. gondii and pathogenic VTEC. If new information confirms these hazards as a high risk to public health from meat from sheep or goats, setting targets at carcass level should be considered. Other elements of the system are risk...... slaughter. For chemical hazards, dioxins and dioxin-like polychlorinated biphenyls were ranked as being of high potential concern. Monitoring programmes for chemical hazards should be more flexible and based on the risk of occurrence, taking into account FCI, which should be expanded to reflect...

    Although titanium and its alloys are widely used as implant material for orthopedic and dental applications they show only limited corrosion stability and osseointegration in different cases. The aim of the presented research was to develop and characterize a novel surface modification system from a thin diamond base layer and a hydroxyapatite (HAp) top coating deposited on the alloy Ti6Al4V widely used for implants in contact with bone. This coating system is expected to improve both the long-term corrosion behavior and the biocompatibility and bioactivity of respective surfaces. The diamond base films were obtained by Microwave Plasma Assisted Chemical Vapor Deposition (MW-PACVD); the HAp coatings were formed in aqueous solutions by electrochemically assisted deposition (ECAD) at varying polarization parameters. Scanning electron microscopy (SEM), Raman microscopy, and electrical conductivity measurements were applied to characterize the generated surface states; the calcium phosphate coatings were additionally chemically analyzed for their composition. The biological properties of the coating system were assessed using hMSC cells analyzing for cell adhesion, proliferation, and osteogenic differentiation. Varying MW-PACVD process conditions resulted in composite coatings containing microcrystalline diamond (MCD/Ti-C), nanocrystalline diamond (NCD), and boron-doped nanocrystalline diamond (B-NCD) with the NCD coatings being dense and homogeneous and the B-NCD coatings showing increased electrical conductivity. The ECAD process resulted in calcium phosphate coatings from stoichiometric and non-stoichiometric HAp. The deposition of HAp on the B-NCD films run at lower cathodic potentials and resulted both in the highest coating mass and the most homogenous appearance. Initial cell biological investigations showed an improved cell adhesion in the order B-NCD>HAp/B-NCD>uncoated substrate. Cell proliferation was improved for both investigated coatings whereas ALP

    Full Text Available English for Specific Purposes (ESP educators often face dilemma in deciding what lexical items to teach their students. In the field of English for Nursing Purposes (ENP, there is no exception on this issue as well. Only by analyzing the nursing corpus made up of essential core textbooks that can provide better insights and guide to both nursing students and educators. This research aims to highlight the 2,000 most frequently used nursing words across the core textbooks of nursing and to profile the types of ‘low frequency’ lexis which comprise the nursing corpus in terms of the General Service List (GSL and Academic Word List (AWL lexis coverage. By knowing the frequently used nursing words would further reduce students’ reading deficiency if the students use the 2000-word list.

  13. Undergraduate medical textbooks do not provide adequate information on intravenous fluid therapy: a systematic survey and suggestions for improvement.

    2014-02-20

    Inappropriate prescribing of intravenous (IV) fluid, particularly 0.9% sodium chloride, causes post-operative complications. Fluid prescription is often left to junior medical staff and is frequently poorly managed. One reason for poor intravenous fluid prescribing practices could be inadequate coverage of this topic in the textbooks that are used. We formulated a comprehensive set of topics, related to important common clinical situations involving IV fluid therapy, (routine fluid replacement, fluid loss, fluids overload) to assess the adequacy of textbooks in common use. We assessed 29 medical textbooks widely available to students in the UK, scoring the presence of information provided by each book on each of the topics. The scores indicated how fully the topics were considered: not at all, partly, and adequately. No attempt was made to judge the quality of the information, because there is no consensus on these topics. The maximum score that a book could achieve was 52. Three of the topics we chose were not considered by any of the books. Discounting these topics as "too esoteric", the maximum possible score became 46. One textbook gained a score of 45, but the general score was poor (median 11, quartiles 4, 21). In particular, coverage of routine postoperative management was inadequate. Textbooks for undergraduates cover the topic of intravenous therapy badly, which may partly explain the poor knowledge and performance of junior doctors in this important field. Systematic revision of current textbooks might improve knowledge and practice by junior doctors. Careful definition of the remit and content of textbooks should be applied more widely to ensure quality and "fitness for purpose", and avoid omission of vital knowledge.

  15. An analysis of how electromagnetic induction and Faraday's law are presented in general physics textbooks, focusing on learning difficulties

    International Nuclear Information System (INIS)

    Guisasola, Jenaro; Zuza, Kristina; Almudi, José-Manuel

    2013-01-01

    Textbooks are a very important tool in the teaching–learning process and influence important aspects of the process. This paper presents an analysis of the chapter on electromagnetic induction and Faraday's law in 19 textbooks on general physics for first-year university courses for scientists and engineers. This analysis was based on criteria formulated from the theoretical framework of electromagnetic induction in classical physics and students' learning difficulties concerning these concepts. The aim of the work presented here is not to compare a textbook against the ideal book, but rather to try and find a series of explanations, examples, questions, etc that provide evidence on how the topic is presented in relation to the criteria above. It concludes that despite many aspects being covered properly, there are others that deserve greater attention. (paper)

  18. 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

    MrDuring last year a new astronomical textbook under title ""ASTRONOMY"" has been prepared. In this book I have tried to keep the spirit of my previous editions started 1972. with first ever printed text on general astronomy in Bosnia-Herzegovina. After five editions the sixth one is a totaly new book. In comparation with fifth edition text of the new Astronomy is not drasticaly changed. But using computer graphics especially computer air brush technics (made by bosnian artist Mr. O. Pavlovic) I think that we produced something new in line of similar leading astronomical textbook in the world. Explantions of some astronomical phenomena who can't be described so easy by words or we are not in position to have direct images of them are much easier when you have color paintings. The new textbook and used approaches can be interesting for others who are involved in astronomical teaching and popularization. Also ASTRONOMY"" will be important step forward looking present situation in astronomy in Bosnia-Herzegovina.

  1. Content Area Textbooks as Sources for Vocabulary Learning

    Directory of Open Access Journals (Sweden)

    Bambang Yudi Cahyono

    2016-02-01

    Full Text Available This study examines the potential of content area textbooks as a lexical environment for incidental vocabulary learning. The two questions proposed are how many rarely-used words content area textbooks contain within a particular number of words, and how different or similar the frequency of rarely-used words is in the linguistic studies and non-linguistic studies textbooks. This study concludes that content area textbooks contain a relatively high frequency of words within Nat3 and Nat4 levels. The high percentage of rarely-used words indicates that content area textbooks are rich sources for vocabulary learning. The findings also suggest that different kinds of textbooks in the content courses can be rich lexical environments for the study of second language vocabulary

    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.

  6. 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.

    2010-10-01

    Full Text Available In this paper we analyzed the presence of the evolution in secondary education textbooks used en Chile since 1902 to 2003. Textbooks analysis of secondary education shows the disputes between evolutionisms and their opponents. Members of the clergy participated actively as antievolutionisms and several of the most outstanding evolutionisms were liberal and francmasones. 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.

    Oman, Auna

    This action research project investigated fourth grade students¡¦ motivation to learn science using a digital science techbook. Participants in the study included 29 fourth grade students in two different classrooms. One classroom of 16 students used a digital science techbook to learn science while the other classroom of 13 students used a traditional paper science textbook to learn science. Students in both classrooms answered five sets of questions regarding their experience using a digital science techbook and a paper science techbook to understand science, find science information, solve science problems, learn science, and assess learning science was fun. Results were compiled and coded based on positive and negative responses to conditions. A chi-square was used to analyze the ordinal data. Overall differences between techbooks vs. textbook were significant, X2 (1, N = 29) = 23.84, p = .000, justifying further examination of individual survey items. Three items had statistically significant difference for finding science information, solving science problems, and learning science. A gender difference was also found in one item. Females preferred to use paper science textbooks to understand science, while males preferred digital techbooks to learn science. The fourth graders in this study indicated that digital techbooks were a powerful learning tool for increasing interest, excitement and learning science. Even though students reported paper science textbooks as easy to use, they found using digital science techbooks a far more appealing way to learn science.

  15. A readability analysis of elementary-level science textbooks

    Science.gov (United States)

    Trainer, Robyn

    Given both the unprecedented attention to the importance of providing children with the best possible science textbooks and the overwhelming evidence that students in the United States are severely lacking the most basic science knowledge, the decline in the number of students pursuing science degrees is alarming. In spite of all the efforts being made, a disparity still exists between (1) the wealth of science information available, (2) the apparent ease of access to scientific information, and (3) the lack of scientific academic progress being made in classrooms across the United States. A literature review was conducted which included the areas of textbook analysis and textbook readability levels, the fields of textbook analysis and readability, and findings from recently published books about textbook readability. The majority of the literature reflected an urgent need for science textbooks to be revised. Based on the information gathered during the literature review, the study examined the readability levels of elementary level science textbooks that were published by six textbook publishers. Results from the study revealed that when used properly, readability formulas provide an objective look at textbooks. After applying these formulas to the selected elementary level science textbooks, it became clear that very few changes were implemented between the most recent previous editions and the current editions. The textbooks remain too difficult for the students using them. The findings from this study will help science textbook publishers and textbook writers see that some changes need to be made in the way their textbooks are written. In order to maintain a competitive edge in the global marketplace, more students need to pursue science. In order for more students to do that, they need to pursue science degrees, but in order for them to pursue science degrees, they need to have a certain degree of confidence and level of interest in the subject matter.

    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.

  1. A Modern Approach to the Traditional Textbook: Bringing Introductory Geology Courses into the 21st Century

    Science.gov (United States)

    Workman Ford, K.; Ford, K. R.

    2013-12-01

    Undergraduate introductory geology courses are required in many colleges nationwide as part of the general education requirement. As a result, a large portion of those students are non-majors and most are not science majors. Textbooks used in these courses are often extensive with respect to the amount of material covered which tends to be overwhelming to the average student. Thus, students often purchase the pricey textbook but turn to their smartphones, notebooks, and laptops for answers. Before the development of the internet, students spent many hours in libraries and with their textbooks organizing and retrieving information. However, new technologies in the 21st century have essentially replaced traditional textbooks with students turning to online search engines, such as Google, to study and to complete homework assignments. Presently, online search engines may be more intuitive, but what's going on in the background isn't intuitive at all, and few students have a clear understanding of how search engines operate. Effectively this leads to students without the conception of how to build an adequate search strategy independent of search engines. Often, students are directed to online encyclopedias that may have erroneous information. Here, we employ an alternative to traditional textbooks and online search engines by implementing a guidebook with electronic resources for online activities and homework assignments. The proposed guidebook is roughly modeled after the American Geosciences Institute's Geoscience Handbook: AGI Data Sheets 4th, revised edition, and will include diagrams, graphs, charts, and pictures of basic geologic principles, processes, and earth materials. Along with the information, each topic will have online resources including sites for general reading, specific assignments that require visiting scientifically sound websites (i.e., USGS, GSA, AGU, Science, Nature), online self-assessment activities, and Google Earth activities. In addition

  11. 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.

  12. A Thorough Scrutiny of ELT Textbook Evaluations: A Review Inquiry

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available The main approaches to defining the concept of electronic textbook have been analyzed in the article. The main advantages of electronic textbooks in the context of future teachers’ training have been outlined. They are interactivity, feedback provision, availability of navigation and search engine. The author has presented and characterized the main stages in the technology of development of an electronic textbook on Handicraft and Technology Training Methodology: determination of its role and significance in the process of mastering the discipline; justification of its structure; outline of the stages of its development in accordance with the defined structure. The characteristic feature of the developed electronic textbook is availability of macro- and microstructure. Macrostructure is viewed as a sequence of components of the electronic textbook that are manifested in its content; microstructure is considered to be an internal pattern of each component of macrostructure.

  11. 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.

  12. Visualizing Geoscience Concepts Through Textbook Art (Invited)

    Science.gov (United States)

    Marshak, S.

    2013-12-01

    Many, if not most, college students taking an introductory geoscience course purchase, borrow, download, or rent one of several commercial textbooks currently available. Art used in such books has evolved significantly over the past three decades. Concepts once conveyed only by black-and-white line drawings, drawn by hand in ink, have gradually been replaced by full-color images produced digitally. Multiple high-end graphics programs, when used in combination, can yield images with super-realistic textures and palettes so that, in effect, anything that a book author wants to be drawn can be drawn. Because of the time and skill level involved in producing the art, the process commonly involves professional artists. In order to produce high-quality geoscience art that can help students (who are, by definition, non-experts) understand concepts, develop geoscience intuition, and hone their spatial-visualization skills, an author must address two problems. First, design a figure which can convey complex concepts through visual elements that resonate with students. Second, communicate the concepts to a professional artist who does not necessarily have personal expertise in geoscience, so that the figure rendered is both technically correct and visually engaging. The ultimate goal of geoscience art in textbooks is to produce an image that avoids unnecessary complexity that could distract from the art's theme, includes sufficient realism for a non-expert to relate the image to the real world, provides a personal context in which to interpret the figure, and has a layout that conveys relationships among multiple components of the art so that the art tells a coherent story. To accomplish this goal, a chain of choices--about perspective, sizes, colors, texture, labeling, captioning, line widths, and fonts--must be made in collaboration between the author and artist. In the new world of computer-aided learning, figures must also be able to work both on the computer screen and

  16. 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.

    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.

    Vicedo, Marga

    2012-03-01

    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.

  10. 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...

    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.

  17. Between training and popularization: Regulating science textbooks in secondary education.

    Science.gov (United States)

    Shapiro, Adam R

    2012-03-01

    Recruitment into the scientific community is one oft-stated goal of science education--in the post-Sputnik United States, for example--but this obscures the fact that science textbooks are often read by people who will never be scientists. It cannot be presupposed that science textbooks for younger audiences, students in primary and secondary schools, function in this way. For this reason, precollegiate-level science textbooks are sometimes discussed as a subset of literature popularizing science. The high school science classroom and the textbook are forums for exposing the public to science. The role of governments and educational institutions in regulating the consumption of these texts not only determines which books are used; it influences how they are written, read, and deemed authoritative. Therefore such science textbooks should not be seen as (at best) the disjunction of texts-for-training and books-for-popularization. A changing sense of what "textbooks" are compels a different understanding of their use in the history of science.

  18. 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.

    Full Text Available In this paper we describe ways to use the Wiki-platform as a tool for learning. In our teaching we have used Wiki's as an on-line text-book, for student collaborative work and as the practical course presentation. The choice of optimal software for a WIKI (e.g. MediaWiki, or Wikispaces depends on the intended use, we describe our experiences with various software in the three cases above. No matter the overall purpose for the use of the Wiki, it has a great functionality that it easily updatable, it is used widely thus the format is known to the students. Besides printed literature more and more teaching material is available in a digital version and accessed either via special software or an internet browser, the same way a wiki is accessed, this automatically integrates the various learning material and gives easy and fast access to relevant information for the students. If you are not a computer expert it is not easy to set up a private web server to host a wiki, however, this can in many cases be avoided by choosing a commercially available Wiki's. We conclude that Wiki's implemented for online educational teaching material help a large part of the students to structure their studies and attain the intended learning outcomes and at least for some students in their collaborative work the learning outcome is above expected for the course.

  1. Need for a contamination control textbook

    International Nuclear Information System (INIS)

    Stowers, I.F.; Patton, H.G.; Guntrum, S.K.

    1980-01-01

    Since the authors have become associated with contamination control technology they have repeatedly found themselves searching for technical information that was either never documented and therefore never reached a technical journal or was too specific to appear in a technical article. On countless occasions they have found other workers frustrated over the same lack of concise and up to date information in the relatively broad and interdisciplinary field of surface science, surface cleaning, and clean room operation and design. It is for these reasons that the authors wish to suggest formally that those engineers, chemists, technicians, and surface scientists working in this field collectively create a textbook that they may use as their first reference and teaching book. The text of this paper suggests a topical outline for a book and gives examples of the kinds of information that it should contain and the types of questions it should address. Included is an extensive bibliography recently collected showing the diversity of disciplines that those working in contamination control must be knowledgeable of and the variety of publications and journals in which these reports and articles are generally found

Jonathan Swift This book emerges from a long story of teaching. I taught chemical engineering thermodynamics for about ten years at the University of Naples in the 1960s, and I still remember the awkwardness that I felt about any textbook I chose to consider-all of them seemed to be vague at best, and the standard of logical rigor seemed immensely inferior to what I could find in books on such other of the students in my first class subjects as calculus and fluid mechanics. One (who is now Prof. F. Gioia of the University of Naples) once asked me a question which I have used here as Example 4. 2-more than 20 years have gone by, and I am still waiting for a more intelligent question from one of my students. At the time, that question compelled me to answer in a way I didn't like, namely "I'll think about it, and I hope I'll have the ...

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

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

    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.

    2009-06-01

    Full Text Available The goal of this paper is to verify up to what point ELT textbooks used in Spanish educational settings comply with the official regulations prescribed, which fully advocate the Communicative Language Teaching Method (CLT. For that purpose, seven representative coursebooks of different educational levels and modalities in Spain – secondary, upper secondary, teenager and adult textbooks – were selected to be analysed. A full unit randomly selected from each coursebook was examined through the parameters of the communicative potential of the activities – measured on a scale from 0 to 10 – and the communicative nature of the methodological strategies implemented – measured on a dichotomous scale (yes/no. Global results per educational levels point to the prevailing communicative nature of all the materials, which was shown to be above 50%. The remaining non-communicative block was covered by activities focused on the formal features of language (grammar and vocabulary. This resulting degree of dissociation between official regulations and what is really found in teaching materials may be positive, since the learning of languages is complex and results from the intervention of multiple factors and learning styles, as is evidenced by the professional experience of teachers from different backgrounds and beliefs.

  14. Misconception and miseducation: Presentations of radical behaviorism in psychology textbooks

    Science.gov (United States)

    Todd, James T.; Morris, Edward K.

    1983-01-01

    Behavior analysts have recently expressed concern about what appear to be misrepresentations of behaviorism in psychology textbooks. This paper presents an analysis of currently used textbooks in the areas of introductory, social, cognitive, personality, and developmental psychology that confirms this. Topics on which behavior analysis is most often misrepresented relate to the role of animal learning research, environmentalism, the “empty organism,” language, and the overall utility of the approach. Because textbooks are often a major medium of interaction between the public and behaviorism, behavior analysts must work to correct these errors and to prevent possible negative consequences of widespread misunderstanding. Several potential solutions to these problems are presented that take into account current publishing practices and the monetary contingencies which support them. PMID:22478585

    2016-12-01

    Full Text Available This paper uses the sentences from the Singapore primary school Chinese textbooks as the research material, using sentence as a unit; analyses sentence composition and sentence patterns, from quantity, distribution, characteristic and semantic type aspects to examine the progression of sentence complexity in Chinese language. The paper describes how the sentence develops in a systemic and complexity aspect in textbooks of various levels. The paper suggests 7 types of sentence pattern grading in term of complexity progression, and proposes a formula to examine and calculate the complexity index of a sentence. The findings derive a set of valuable data to expound the complexity of a sentence and discuss the variable factors influencing the complexity of sentences used in primary school Chinese textbooks.

  16. Toward textbook multigrid efficiency for fully implicit resistive magnetohydrodynamics

    KAUST Repository

    Adams, Mark F.

    2010-09-01

    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.

    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.

    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.

  20. 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.

    The purpose of the final cover of a landfill is to contain the waste and to provide for a physical separation between the waste and the environment for protection of public health. Most landfill covers are designed with the primary goal to reduce or prevent infiltration of precipitation...... into the landfill in order to minimize leachate generation. In addition the cover also has to control the release of gases produced in the landfill so the gas can be ventilated, collected and utilized, or oxidized in situ. The landfill cover should also minimize erosion and support vegetation. Finally the cover...... is landscaped in order to fit into the surrounding area/environment or meet specific plans for the final use of the landfill. To fulfill the above listed requirements landfill covers are often multicomponent systems which are placed directly on top of the waste. The top cover may be placed immediately after...

  3. Recurring errors among recent history of psychology textbooks.

    Science.gov (United States)

    Thomas, Roger K

    2007-01-01

    Five recurring errors in history of psychology textbooks are discussed. One involves an identical misquotation. The remaining examples involve factual and interpretational errors that more than one and usually several textbook authors made. In at least 2 cases some facts were fabricated, namely, so-called facts associated with Pavlov's mugging and Descartes's reasons for choosing the pineal gland as the locus for mind-body interaction. A fourth example involves Broca's so-called discovery of the speech center, and the fifth example involves misinterpretations of Lloyd Morgan's intentions regarding his famous canon. When an error involves misinterpretation and thus misrepresentation, I will show why the misinterpretation is untenable.

    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.

    Gouda, Hebe N; Powles, John W

    2014-02-10

    Epidemiology is often described as 'the science of public health'. Here we aim to assess the extent that epidemiological methods, as covered in contemporary standard textbooks, provide tools that can assess the relative magnitude of public health problems and can be used to help rank and assess public health priorities. Narrative literature review. Thirty textbooks were grouped into three categories; pure, extended or applied epidemiology, were reviewed with attention to the ways the discipline is characterised and the nature of the analytical methods described. Pure texts tend to present a strict hierarchy of methods with those metrics deemed to best serve aetiological inquiry at the top. Extended and applied texts employ broader definitions of epidemiology but in most cases, the metrics described are also those used in aetiological inquiry and may not be optimal for capturing the consequences and social importance of injuries and disease onsets. The primary scientific purpose of epidemiology, even amongst 'applied' textbooks, is aetiological inquiry. Authors do not readily extend to methods suitable for assessing public health problems and priorities.

    Textbook content is a powerful indicator of what is and is not considered important in a given discipline. Textbooks shape both curriculum and students' thinking about a subject. The extant literature indicates that gender is not well represented in American government textbooks, thus signaling to students that women and gender are not part of the…

Although previous research has documented this lack of preference for e-textbooks, student performance and use of…

    2015-10-01

    On October 13, 1804, Seishu Hanaoka performed a mastectomy on Kan Aiya in Hirayama, Kii Province Japan, in what is considered to be the first operation under general anesthesia. She was anesthetized with a mixture of herbs known as Mafutsuto. Although Seishu did not record his anesthetic practices, his student, Gendai Kamada, documented the use of Mafutsuto in Mafutsuto-Ron. Written in 1839, Mafutsuto-Ron is 10 pages and covers six topics, including preoperative management, dosing and administering Mafutsuto, induction of general anesthesia, common errors, and postoperative precautions. Mafutsuto-Ron, therefore, meets the requirements to be considered the first extant anesthesia textbook. We present a complete English translation of Mafutsuto-Ron. Copyright © 2015 Elsevier B.V.

  1. ORAL DISCURSIVE GENRE APPROACH IN SPANISH LANGUAGE TEXTBOOKS

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Several studies point that the oral genres have been marginalized in the classroom. However, often, difficulties in oral communication arise because a lack of knowledge about the discursive genre, although the speaker has the knowledge about the linguistic system. From this evidence and considering the role of textbooks in the language teaching learning process, in this article we aim to analyze how oral genres are treated on two textbooks of Spanish language. For this, we carry out a bibliographic research in which we analyzed textbooks chosen by the Programa Nacional do Livro Didático (PNLD, in the years of 2012 and 2015. To achieve our goal, we exposed a theoretical overview about discursive genres and oral discursive genres, present the methodology adopted and the performed analyzes, which made it possible to note that in the collections there are still primacy by the pedagogical work from written genres, although when comparing the approach, the latest textbook presents more activities with oral discursive genres.

  13. Representation of Hidden Curriculum in EFL Textbook (Gender Markers

    Directory of Open Access Journals (Sweden)

    Ekaterina E. Shishlova

    2014-01-01

    Full Text Available The article considers the mechanism ofrepresenting the hidden curriculum in the discourse of EFL textbooks, i.e. the transmission ofsociocultural norms and values of native speakers to foreign students. To do this the authors make a brieftheoretical review of this problem and demonstrate the results of the comparative discourse analysis of two popular textbooks, the one of the pre-globalization age and the present-day one. The authors provide evidence for their idea of the dual role, which English plays today being simultaneously a national language of different English-speaking societies and the global lingua franca. The conducted discourse analysis is based on the analysis of semiotic means, which are used to nominate concepts basic to any society and culture. In the article, the authors demonstrate their own plan of analysis by the example of the "gender" concept. The gender concept shows social and cultural conditionality of distinctions in behavior and the identity of men and women. The comparative analysis of gender markers in the discourse of EFL textbooks reveals a global vector of transformation and distribution ofsociocultural values. Authors state that cultural expansion through English teaching is an instrument of smart power. It is suggested using the mechanism of transmission ofsociocultural norms and values, which is analyzed in the research, to create Russian textbooks for foreign students.

  7. 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.

  10. Implementing Digital Interactive Textbooks in the Science Classroom

    Science.gov (United States)

    Allen, Gary R.

    Digital interactive textbooks represent a major step forward in the quest to integrate technology into instructional methodology. Because this technology is new, virtually no research has been done as to the response of teachers to this innovation. The purpose of this study was to understand the process of change in relation to implementing these digital interactive textbooks in science classrooms at the high school level. The conceptual framework was based on Senge's theory of organizational change, Rogers' theory of the diffusion of innovations, and Davis' research regarding factors involved in technology acceptance. Participants included 7 science teachers and 2 administrators who were members of a professional learning community at a Title I high school in the southeastern region of the United States. A case study design was used to collect data from teacher and administrator interviews and observations of instructional activities in the classroom and professional learning community meetings. Data were coded, categorized, and analyzed for common themes. Results indicated that the digital interactive textbook was met with teacher apprehension and anxiety regarding the transition from teacher-led to student-led instruction, and this apprehension manifested in resistance. During the course of the study, educators found that the digital interactive textbook engaged students and was demonstrated to be a successful tool of instruction. The study is important because educators will develop a better understanding of how to implement technology innovations in the classroom that minimize teacher resistance to instructional change.

    Sternberg, Robert J.

    2017-01-01

    Although academics are accustomed to writing articles and books, they much less frequently write textbooks. When they do, they likely find it much harder to do well than they ever would have imagined. This difficulty is likely to surprise them, because they have considerable experience in writing research articles and in teaching. I argue in this…

  9. 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.

  10. Values of individualization in science & social studies textbooks

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Ways of achieving individualization of the learning process are one of the most important issues of modern didactics. They represent a new approach to creating modern systems of teaching. There is a growing discussion about developmental teaching that can be characterized as a model of individualized teaching. This is the answer to the classical organization of teaching in a class-lecture system in which teaching content, teaching methods, learning styles and all other working conditions are the same for all students. Therefore, the creation of a modern Science & Social Studies textbook which should meet the requirements of modern teaching has a great social importance and requires joint efforts of theoreticians, researchers and practitioners. When the textbooks is well-designed, we can expect improved student activity in didactic and methodological sense, development of his individuality and creativity, as well as positive influence on his self-formation and self-actualization. Starting from the notion of individualization, the textbook as an assumed scenario of the learning and teaching process, the authors determine the goal of the research: to examine the presence of values of individualization in Science & Social Studies textbooks for the fourth grade of primary school. The research sample is deliberate and stratified: it consists of Science & Social Studies textbooks for the fourth grade of primary school, published by the Institute for Textbooks Publishing and Teaching Aids. 121 primary school teachers from the Zlatibor and Moravicki Districts participated in this research. Independent evaluators assessed the distribution of several categories that relate to the values of individualization: 1 content in two levels of difficulty - remedial content for students with poor performance and additional content for good students; 2 examples designed in three levels of difficulty - for students with the weakest performance, for average students

    Full Text Available Textbooks play a very crucial role in the process of language teaching and learning. The present study carries out an evaluation of two series of ELT textbooks used for teaching English language in Iranian high schools since 1970 to 2010. For this purpose, Tucker’s (1975 textbook evaluation model (see Appendix has been employed. The results suggest that one of the main factors for the students’ achievement in English language is the ELT textbooks. The researcher suggests that in the textbooks, there should be enough opportunity for the learners to communicatively practice the language they are learning.

  17. An undergraduate course, and new textbook, on ``Physical Models of Living Systems''

    Science.gov (United States)

    Nelson, Philip

    2015-03-01

    I'll describe an intermediate-level course on ``Physical Models of Living Systems.'' The only prerequisite is first-year university physics and calculus. The course is a response to rapidly growing interest among undergraduates in several science and engineering departments. Students acquire several research skills that are often not addressed in traditional courses, including: basic modeling skills, probabilistic modeling skills, data analysis methods, computer programming using a general-purpose platform like MATLAB or Python, dynamical systems, particularly feedback control. These basic skills, which are relevant to nearly any field of science or engineering, are presented in the context of case studies from living systems, including: virus dynamics; bacterial genetics and evolution of drug resistance; statistical inference; superresolution microscopy; synthetic biology; naturally evolved cellular circuits. Publication of a new textbook by WH Freeman and Co. is scheduled for December 2014. Supported in part by EF-0928048 and DMR-0832802.

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

    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.

    Full Text Available Can folding a piece of paper flat make it larger? We explore whether a shape S must be scaled to cover a flat-folded copy of itself. We consider both single folds and arbitrary folds (continuous piecewise isometries \\(S\\to\\mathbb{R}^2\\. The underlying problem is motivated by computational origami, and is related to other covering and fixturing problems, such as Lebesgue's universal cover problem and force closure grasps. In addition to considering special shapes (squares, equilateral triangles, polygons and disks, we give upper and lower bounds on scale factors for single folds of convex objects and arbitrary folds of simply connected objects.

  2. Evapotranspiration (ET) covers.

    2012-01-01

    Evapotranspiration (ET) cover systems are increasingly being used at municipal solid waste (MSW) landfills, hazardous waste landfills, at industrial monofills, and at mine sites. Conventional cover systems use materials with low hydraulic permeability (barrier layers) to minimize the downward migration of water from the surface to the waste (percolation), ET cover systems use water balance components to minimize percolation. These cover systems rely on soil to capture and store precipitation until it is either transpired through vegetation or evaporated from the soil surface. Compared to conventional membrane or compacted clay cover systems, ET cover systems are expected to cost less to construct. They are often aesthetic because they employ naturalized vegetation, require less maintenance once the vegetative system is established, including eliminating mowing, and may require fewer repairs than a barrier system. All cover systems should consider the goals of the cover in terms of protectiveness, including the pathways of risk from contained material, the lifecycle of the containment system. The containment system needs to be protective of direct contact of people and animals with the waste, prevent surface and groundwater water pollution, and minimize release of airborne contaminants. While most containment strategies have been based on the dry tomb strategy of keeping waste dry, there are some sites where adding or allowing moisture to help decompose organic waste is the current plan. ET covers may work well in places where complete exclusion of precipitation is not needed. The U.S. EPA Alternative Cover Assessment Program (ACAP), USDOE, the Nuclear Regulatory Commission, and others have researched ET cover design and efficacy, including the history of their use, general considerations in their design, performance, monitoring, cost, current status, limitations on their use, and project specific examples. An on-line database has been developed with information

The chemistry books introduce concepts that should relate biochemistry to students in schools. It is important that this first contact turns out into an encouraging experience for the students, because once it worked as expected it arouses interest and makes the students see themselves curious to delve into the subject. The research aims to evaluate the presence of related concepts in biochemistry textbooks in chemistry in high school, over 20 years. MATERIAL AND METHODS: In order to perform this study, we analyzed the following content related to biochemistry: proteins, carbohydrates, lipids and nucleic acids in the books "Chemistry - Structure of Matter and Organic Chemistry" of the year 1993 and the book "Chemistry in approach to daily life" of the year 2012 with the purpose of verifying the changes in the content of biochemistry in the last 20 years. RESULTS AND DISCUSSION: In the 90s, as used in the book, concepts and explanations are introduced in a very objective approach, making a total of 22 pages. The current largest is 23 pages with experiments and curiosities. Through analysis we found that current textbooks present the same issues related to biochemistry, however, a greater amount of data, bringing students to more examples and applications in everyday life. Today we see that the contents and processes are most exploited and that there is a concern on the importance of the study of issues that relate to biochemistry. CONCLUSIONS: The study of the biochemistry textbooks has been more attractive in recent years, contextualizing content with the daily life of

    The reformation of the "Object Formerly Known as Textbook" (coined by the Chronicle of Higher Education) toward a digital future is underway. Emerging nextgen texts look less like electronic books ("ebooks") and more like online courseware. In addition to text and illustrations, nextgen textbooks for STEM subjects are likely to combine quizzes, grade management tools, support for social learning, and interactive media including web maps. Web maps are interactive, multi-scale, online maps that enable teachers and learners to explore, interrogate, and mash up the wide variety of map layers available in the cloud. This presentation will show how web maps coupled with interactive quizzes enable students' purposeful explorations and interpretations of spatial patterns related to humankind's interactions with the earth. Attendees will also learn about Esri's offer to donate ArcGIS Online web mapping subscriptions to every U.S. school as part of the President Obama's ConnectED initiative.

    Students who enroll for the special access course in physics at the University of Cape Town generally do not speak English as first language and have experienced poor science teaching. As a consequence students experience a large range of difficulties in trying to learn physics. We discuss research carried out in two such areas (a) understanding of measurement and (b) engagement with the textbook. With regard to (a) an overview of the methodology, analysis framework and findings of previous work will be presented together with more recent preliminary findings regarding audience dependence when conveying measurement results. With regard to (b) the idea of writing chapter summaries was used to guide students through the book with the aim that the textbook would come to be valued an accessible resource. Findings from the analysis of the student summaries are presented

    Science.gov (United States)

    Franklin, Allan

    2016-04-01

    Anyone who studies the history of physics quickly realizes that the history presented in physics textbooks is often inaccurate. I will discuss three episodes from the history of modern physics: (1) Robert Millikan's experiments on the photoelectric effect, (2) the Michelson-Morley experiment, and (3) the Ellis-Wooster experiment on the energy spectrum in β decay. Everyone knows that Millikan's work established the photon theory of light and that the Michelson-Morley experiment was crucial in the genesis of Albert Einstein's special theory of relativity. The problem is that what everyone knows is wrong. Neither experiment played the role assigned to it by physics textbooks. The Ellis-Wooster experiment, on the other hand, is rarely discussed in physics texts, but it should be. It led to Wolfgang Pauli's suggestion of the neutrino. I will present a more accurate history of these three experiments than those given in physics texts.

  15. EQUATIONS AND THE EQUAL SIGN IN ELEMENTARY MATHEMATICS TEXTBOOKS

    Science.gov (United States)

    Powell, Sarah R.

    2012-01-01

    To promote a relational understanding of the equal sign (=), students may require exposure to a variety of equation types (i.e., 3 = 8 − 5; 2 + 3 = 1 + 4; 9 − 3 = 6). The purpose of this study was to evaluate 8 elementary curricula for degree of exposure to equation types. Across 6 elementary grade levels, curricula were coded for the number of standard and nonstandard equation types appearing within the student textbook. Except in 1 of the 8 curricula, students typically do not receive exposure to nonstandard equation types that promote a relational understanding of the equal sign. An analysis of the accompanying teacher manual for each textbook suggests that students receive minimal instruction on relational definitions of the equal sign, with the majority of instruction occurring in grades K–2 and minimal instruction provided in grades 3–5.

The sample was composed of 2,583 images and 87 secondary school pupils. The analysis was carried out through the elaboration of an ad hoc coding scheme. The results showed that people whose appearance is similar to the in-group predominate. The kind of physical activity, the field, space, and level of competence vary according to race. The textbooks analyzed in this study engender a stigmatized vision of racial diversity, and the images reproduce and reinforce racial prejudice.

    1996-04-01

    The development of on-line engineering textbooks presents new challenges to authors to effectively integrate text and tools in an electronic environment. By incorporating human factors principles of interface design and cognitive psychology early in the design process, a team at Sandia National Laboratories was able to make the end product more usable and shorten the prototyping and editing phases. A critical issue was simultaneous development of paper and on-line versions of the textbook. In addition, interface consistency presented difficulties with distinct goals and limitations for each media. Many of these problems were resolved swiftly with human factors input using templates, style guides and iterative usability testing of both paper and on-line versions. Writing style continuity was also problematic with numerous authors contributing to the text.

    It is my assumption that our way of understanding globalization in the last two decades has changed the subject matter of history. The focus has shifted from the regional and national to the global perspective. This is evident if we analyze German and Danish textbooks on history. This development and its consequences have only been vaguely reflected in the debates on history didactics. Perhaps we have accepted this development as unavoidable as it is often done in economic discourses? To my o...

  2. Do You Need a Textbook to Teach Astro 101?

    Science.gov (United States)

    Rudolph, Alexander L.; Collaboration of Astronomy Teaching Scholars CATS

    2011-01-01

    During educational sessions at astronomy meetings, especially during Center for Astronomy Education (CAE) Teaching Excellence workshops, which I have attended and now help present, one of the questions everyone wants to discuss is which textbook to use to teach Astro 101 classes (general education astronomy courses for non-science majors). Some instructors have a favorite. Others will claim that they are all the same and that it doesn't matter. Increasingly, however, the discussions turn to the question of whether any textbook is needed at all. Some of this discussion has been driven by the increase in the use of interactive learning strategies such as Think-Pair-Share questions, Lecture-Tutorials, and Ranking Tasks. These activities provide students a learning modality very different from the traditional lecture supplemented by homework, and raises the question of whether the learning that takes place during such interactive activities is enough to teach students what we wish them to know about astronomy. I had been teaching an Astro 101 class for almost three years using a full suite of interactive learning strategies, when I decided to teach it without requiring the students to purchase a textbook. Comparison of test scores before and after this change shows that there is no statistical difference in student achievement whether a textbook is required or not. Details on the course and methodology used to reach this conclusion will be presented.

    The use of metallic iron as environmental remediation medium was based on an incorrect interpretation of experimental observations. Since then, faced with seemingly contradictory data, researchers have substantially revised their models but controversial reports are still current, suggesting that a substantial revision is unavoidable. This communication analyses redox processes in Fe0/H2O systems and demonstrates that the current paradigm even contradicts textbook knowledge on aqueous iron co...

    This study was performed to develop the electronic textbook (CD-rom title) about preclinical practice of oral and maxillofacial radiology, using multimedia technology with interactive environment. After comparing the three authoring methods of multimedia, i.e. programming language, multimedia authoring tool and web authoring tool, we determined the web authoring tool as an authoring method of our electronic textbook. Intel Pentium II 350 MHz IBM-compatible personal computer with 128 Megabyte RAM, Umax Powerlook flatbed scanner with transparency unit, Olympus Camedia 1400L digital camera, ESS 1686 sound card, Sony 8 mm Handycam, PC Vision 97 pro capture board, Namo web editor 3.0, Photoshop 3.0, ThumbNailer, RealPlayer 7 basic and RealProducer G2 were used for creating the text document, diagram, figure, x-ray image, video and sound files. We made use of javascripts for tree menu structure, moving text bar, link button and spread list menu and image map etc.. After creating all files and hyperlinking them, we burned out the CD-rom title with all of the above multimedia data, Netscape communicator and plug in program as a prototype. We developed the dental radiology electronic textbook which has 9 chapters and consists of 155 text documents, 26 figures, 150 x-ray image files, 20 video files, 20 sound files and 50 questions with answers. We expect that this CD-rom title can be used at the intranet and internet environments and continuous updates will be performed easily.

  5. Oral Health and Hygiene Content in Nursing Fundamentals Textbooks

    Full Text Available The purpose of this paper is to describe the quantity and quality of oral hygiene content in a representative sample of before-licensure nursing fundamentals textbooks. Seven textbooks were examined. Quantity was operationalized as the actual page count and percentage of content devoted to oral health and hygiene. Quality of content was operationalized as congruency with best mouth care practices. Best mouth care practices included evidence-based and consensus-based practices as published primarily by the American Dental Association and supported by both published nursing research and review articles specific to mouth care and published dental research and review articles specific to mouth care. Content devoted to oral health and hygiene averaged 0.6%. Although the quality of the content was highly variable, nearly every textbook contained some erroneous or outdated information. The most common areas for inaccuracy included the use of foam sponges for mouth care in dentate persons instead of soft toothbrushes and improper denture removal.

  6. [Textbooks of western medicine in the early modernization period].

    The first modern hospital, royal Kwang-Hye-Won (House of Extended Grace) was established in April of 1885, whose name was changed into royal Che-Jung-Won (House of Helpfulness) in several days. Private (not royal) Je-Jung-Won opened its Medical School in 1899. And the teachers composed of western missionaries taught some Korean student-assistants the Western medicine with English textbooks in English. With very low effectiveness of teaching due to language barrier, Dr. Avison, the principal of that school decided to write medical textbooks in Korean. At first he tried to translate Henry Gray's Anatomy of 1859. In the effort he referred some Chinese and Japanese medical books. With that reason, we can find many Japanese style medical terms in some medical books of his. On the other hand, Eui-Hak-Kyo (the Medical School) was established by the Government of Dae-Han Empire in 1899. The teaching staff of the school published medical textbooks in Korean, some of which were written by Japanese doctors. After the Japanese annexation of Korea in 1910, Japanese government forced teachers of the school to teach with Japanese medical books and to speak Japanese in teaching. ...

  7. Socioscientific Issues and Multidisciplinarity in School Science Textbooks

    The inclusion of socioscientific issues (SSIs) in the science curriculum is a well-established trend internationally. Apart from claims about its innate value, one of the rationales for this approach is its potential for helping to counter declining interest and participation. SSIs involve the use of science and are of interest to society, also raising ethical and moral dilemmas. Introducing such problems presents a significant and usually cross-disciplinary challenge to curriculum developers and teachers. The aim of this paper is to examine how this challenge has been met when judged against contemporary views of the issues concerned. It first explores how SSIs have been interpreted in an important and innovative science course for students aged 14-16 in England, entitled Twenty First Century Science. This paper analyses the Twenty First Century Science textbooks, focusing in detail on two SSIs, reproductive genetic technology and climate change. For each of these issues, the key ideas present in the social science literature surrounding the problems are outlined. This review is then used as an analytical framework to examine how the issues are presented in the textbooks. It is argued in this paper that the perspectives the textbooks take on these issues largely do not include perspectives from social science disciplines. It goes on to suggest that the development of future SSI-based curricula needs to take account of these wider, often interdisciplinary, perspectives.

    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. PMID:21364103

    The principles of bone biology and physiology permeate all subspecialty practices in plastic and reconstructive surgery from hand surgery to aesthetic surgery. Despite its importance in our practices, the biology of bone healing and bone physiology rarely surfaces within textbooks, literature reviews, or residency curricula. In this article, the authors present the first of a two-part series reviewing the important concepts of bone biology and bone physiology relevant to plastic surgery in an effort to ameliorate this educational gap.

    1.1. INTRODUCTION Plastic covering, either framed or floating, is now used worldwide to protect crops from unfavorable growing conditions, such as severe weather and insects and birds. Protected cultivation in the broad sense, including mulching, has been widely spread by the innovation of plastic films. Paper, straw, and glass were the main materials used before the era of plastics. Utilization of plastics in agriculture started in the developed countries and is now spreading to the developing countries. Early utilization of plastic was in cold regions, and plastic was mainly used for protection from the cold. Now plastic is used also for protection from wind, insects and diseases. The use of covering techniques started with a simple system such as mulching, then row covers and small tunnels were developed, and finally plastic houses. Floating mulch was an exception to this sequence: it was introduced rather recently, although it is a simple structure. New development of functional and inexpensive films trig...

  11. 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...

    priorities. One hundred textbooks were collected, with 663 health messages. The priorities most frequently covered in the textbooks were diet, physical exercise and the impact of environmental contamination. The least frequently covered topics was bullying, child maltreatment, poverty, self harm, and obesity. The latter topic was especially lacking in kindergartens and elementary schools. Conclusions: The health messages contained in school textbooks are not well adapted to the priorities defined by health organizations.

    2011-01-01

    Full Text Available This study aims to examine the oral communicative activities found in the Saudi EFL third year secondary textbooks and to determine the role they play in influencing the learners' oral communication in English. A questionnaire of 52 items based on four domains is utilized to explore the perception of Saudi EFL teachers regarding the oral communicative activities found in the textbooks. The preliminary survey, conducted on a group of Saudi teachers who are using the target textbooks, showed that the textbooks do not have highly communicative activities for fluency development. The participants' rating of the activities, found in the textbooks, was very low. The activities seem to be highly structured and lack free communicative activities. The study shows that the textbooks require much modification. Other types of oral communicative activities should be included to fulfill the goals of developing the Saudi learners' oral fluency in English.

    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.
