    Sport specialization is a strategy to acquire superior sport performance in 1 sport but is associated with increased injury risk. Currently, the degree of high school specialization among Division I athletes is unknown. College athletes will display increased rates of specialization as they progress through their high school careers. Descriptive epidemiological study. Level 4. Three hundred forty-three athletes (115 female) representing 9 sports from a Midwest Division I University completed a previously utilized sport specialization questionnaire regarding sport participation patterns for each grade of high school. McNemar and chi-square tests were used to investigate associations of grade, sport, and sex with prevalence of sport specialization category (low, moderate, high) (a priori P ≤ 0.05). Specialization increased throughout high school, with 16.9% (n = 58) and 41.1% (n = 141) of athletes highly specialized in 9th and 12th grades, respectively. Football athletes were less likely to be highly specialized than nonfootball athletes for each year of high school ( P 0.23). The majority of Division I athletes were not classified as highly specialized throughout high school, but the prevalence of high specialization increased as athletes progressed through high school. Nonfootball athletes were more likely to be highly specialized than football athletes at each grade level. Most athletes who are recruited to participate in collegiate athletics will eventually specialize in their sport, but it does not appear that early specialization is necessary to become a Division I athlete. Athletes should be counseled regarding safe participation in sport during high school to minimize injury and maximize performance.

    2012-08-10

    Tobacco use continues to be the leading preventable cause of death and disease in the United States, with nearly 443,000 deaths occurring annually because of cigarette smoking and exposure to secondhand smoke. Moreover, nearly 90% of adult smokers begin smoking by age 18 years. To assess current tobacco use among youths, CDC analyzed data from the 2011 National Youth Tobacco Survey (NYTS). This report describes the results of that analysis, which indicated that, in 2011, the prevalence of current tobacco use among middle school and high school students was 7.1% and 23.2%, respectively, and the prevalence of current cigarette use was 4.3%, and 15.8%, respectively. During 2000-2011, among middle school students, a linear downward trend was observed in the prevalence of current tobacco use (14.9% to 7.1%), current combustible tobacco use (14.0% to 6.3%), and current cigarette use (10.7% to 4.3%). For high school students, a linear downward trend also was observed in these measures (current tobacco use [34.4% to 23.2%], current combustible tobacco use [33.1% to 21.0%], and current cigarette use [27.9% to 15.8%]). Interventions that are proven to prevent and reduce tobacco use among youths include media campaigns, limiting advertisements and other promotions, increasing the price of tobacco products, and reducing the availability of tobacco products for purchase by youths. These interventions should continue to be implemented as part of national comprehensive tobacco control programs and should be coordinated with Food and Drug Administration (FDA) regulations restricting the sale, distribution, and marketing of cigarettes and smokeless tobacco products to youths.

    This study investigates trends in tobacco use based on gender, race, and grade level among Mississippi public high school students during 1993-2009. Data were obtained by combining eight weighted Mississippi Youth Risk Behavior Surveys (YRBS). Current tobacco use (cigarette, smokeless, and cigar) was selected for investigation. During 1993-2009, the prevalence of current cigarette and cigar use among Mississippi public high school students showed a significant linear decrease (p tobacco use. Male students were more likely to be current tobacco users. White students were more likely to use cigarettes and smokeless tobacco. Programs that target male and white students on certain products such as smokeless tobacco are needed to further decrease overall tobacco use in the state.

    Full Text Available Abstract Background Alcohol drinking is frequently related to behavioral problems, which lead to a number of negative consequences. This study was to evaluate the characteristics of male high school students who drink, the drinking patterns among them, and the associations between current drinking and other health risk behaviors which focused on personal safety, violence-related behaviors, suicide and sexual behaviors. Method A cross-sectional study was conducted to explore current alcohol drinking and health-risk behaviors among male high school students in central Thailand. Five thousand one hundred and eighty four male students were classified into 2 groups according to drinking in the previous 30 days (yes = 631, no = 4,553. Data were collected by self-administered, anonymous questionnaire which consisted of 3 parts: socio-demographic factors, health-risk behaviors and alcohol drinking behavior during the past year from December 2007 to February 2008. Results The results showed that the percent of current drinking was 12.17. Most of them were 15-17 years (50.21%. Socio-demographic factors such as age, educational level, residence, cohabitants, grade point average (GPA, having a part time job and having family members with alcohol/drug problems were significantly associated with alcohol drinking (p Conclusions An increased risk of health-risk behaviors, including driving vehicles after drinking, violence-related behaviors, sad feelings and attempted suicide, and sexual behaviors was higher among drinking students that led to significant health problems. Effective intervention strategies (such as a campaign mentioning the adverse health effects and social consequences to the risk groups, and encouraging parental and community efforts to prevent drinking among adolescents should be implemented to prevent underage drinking and adverse consequences.

    McManic, Janet A.

    The purpose of this study was to investigate students' perceptions of motivation to achieve while participating in general level high school biology classes. In a national poll of teacher's attitudes, student's motivation was a top concern of teachers (Elam, 1989). The student's perceptions of motivation are important to understand if improvements and advancements in motivation are to be implemented in the science classroom. This qualitative study was conducted in an urban high school that is located in a major metropolitan area in the southeast of the United States. The student body of 1100 is composed of Caucasian, African-American, Hispanic, and Asian students. The focus question of the study was: What are students' perceptions of their motivation in biology class? From general level biology classes, purposeful sampling narrowed the participants to fifteen students. Semi-structured interviews were conducted with the participants having varying measurements of motivation on the Scale of Intrinsic versus Extrinsic Orientation in the Classroom (Harter, 1980). The interviews were recorded and transcribed. After transcription, the interviews were coded by the constant comparative method (Glaser & Strauss, 1967). The coded data of students' responses were analyzed and compared to current theories of motivation. The current theories are the social-cognitive model (Bandura, 1977), attribution theory (Weiner, 1979), basic needs theory (Maslow, 1954) and choice theory (Glasser, 1986). The results of this study support the social cognitive model of motivation (Bandura, 1977) through the description of family structure and its relationship to motivation (Gonzalez, 2002). The study upheld previous research in that extrinsic orientation was shown to be prevalent in older students (Harter, 1981; Anderman & Maehr, 1994). In addition, the students' responses disclosed the difficulties encountered in studying biology. Students expressed the opinion that biology terms are

    Bolden, Shenell L. T.

    The purpose of this exploratory study was to examine key stakeholders' perceptions of the current Baltimore City Public Schools' (BCPS) sex education curriculum and to gain insight into how they believe the curriculum could be modified to be more effective. A mixed methods approach using qualitative and quantitative data collection consisting of a survey, focus group interview, and individual interviews was conducted to gather information on stakeholders' perceptions. The stakeholders included: (1) former students who received their sex education courses in the Baltimore City Public School system (BCPS); (2) teachers in BCPS who were affiliated with the sex education curriculum; (3) health care professionals who screened and/or treated East Baltimore City residents for a sexually transmitted disease (STD) and; (4) one policy maker who was responsible for creating sex education curriculum at the national level. Analysis of the quantitative data from former Baltimore City Public School students revealed a general satisfaction with the current sex education curriculum. However, qualitative data from the same group of stakeholders revealed several changes they thought should be implemented into the program in an effort to improve the current curriculum. Findings from the other groups after qualitative analysis of the interviews suggest three major themes in support of curriculum change: (1) a blended curriculum that integrates both the cognitive and affective learning domains; (2) knowledge of prevention of STD's and pregnancy; and (3) authentic teaching and learning. Results from this study strongly suggest that the Baltimore City Public School system is apathetic to the sexual health needs of students and, therefore, is inadvertently contributing to the high rate of sexually transmitted diseases among young people. Keywords: Abstinence, Affective domain, Indoctrination, Behavior Modification, Cognitive domain, Sex education curriculum, Sexually Transmitted Diseases.

    Wormington, Stephanie V; Anderson, Kristen G; Corpus, Jennifer Henderlong

    2011-11-01

    The current study investigated the relationship between different types of academic motives-specifically, intrinsic motivation, introjected regulation, and external regulation-and high school students' current and lifetime alcohol consumption. One thousand sixty-seven high school students completed measures of academic motivation, other school-related factors, and lifetime and current alcohol consumption. Using structural equation modeling, different types of motivation and school-related factors were differentially related to student drinking. Specifically, intrinsic motivation was negatively related to lifetime and current alcohol consumption. External regulation, on the other hand, was positively associated with current drinking. Grade point average was the only school-related factor related to student alcohol use. These findings suggest that motivation is an important construct to consider in predicting students' alcohol use, even when other more commonly studied educational variables are considered. In addition, it supports the adoption of a motivation framework that considers different types of motivation in understanding the relationship between academic motivation and alcohol use. Suggestions for incorporating the self-determination model of motivation into studies of alcohol and substance use, as well as potential impacts on intervention efforts, are discussed. In particular, it may be important to foster only certain types of motivation, rather than all types of academically-focused motives, in efforts to deter alcohol use.

    E-cigarette use among adolescents has increased significantly in recent years, but it remains unclear whether cigarette smoking behaviors and intentions for future cigarette smoking differ among current (i.e., 30-day) non-users, only e-cigarette users, only cigarette smokers, and dual users. A nationally representative sample of 4385 U.S. high school seniors were surveyed during the spring of their senior year via self-administered questionnaires in 2014. An estimated 9.6% of U.S. high school seniors reported current e-cigarette use only, 6.3% reported current cigarette smoking only, and 7.2% reported current dual use of e-cigarettes and cigarette smoking. There were no significant differences between current only cigarette smokers and dual users in the odds of early onset of cigarette smoking, daily cigarette smoking, intentions for future cigarette smoking, friends' cigarette smoking behaviors, attempts to quit cigarette smoking, or the inability to quit cigarette smoking. Adolescents who only used e-cigarettes had higher odds of intentions for future cigarette smoking in the next 5years (AOR=2.57, 95% CI: 1.21-5.24) than current non-users. Dual users and only cigarette smokers had higher odds of cigarette smoking behaviors and intentions for future cigarette smoking than non-users or only e-cigarette users. Adolescents who engage in current dual use have cigarette smoking behaviors and intentions for future cigarette smoking that more closely resemble cigarette smokers than e-cigarette users. Adolescents who only use e-cigarettes have higher intentions to engage in future cigarette smoking relative to their peers who do not engage in e-cigarette use or cigarette smoking.

    Currently, little is known about strength and conditioning programs at the high school level. Therefore, the purpose of this research was to explore current practices in strength and conditioning for varsity high school athletes in selected sports. The following were specifically examined: who administers programs for these athletes, what kinds of training activities are done, and whether the responsible party or emphasis changes depending on the gender of the athletes. Coaches of varsity soccer, basketball, softball, and baseball in 3 large Idaho school districts were asked to complete an online survey. Sixty-seven percent (32/48) of the questionnaires were completed and used for the study. The majority of coaches (84%) provided strength and conditioning opportunities for their athletes, although only 37% required participation. Strength training programs were designed and implemented primarily by either physical education teachers or head coaches. Compared with coaches of male athletes, coaches of female athletes were less likely to know the credentials of their strength coaches, and they were less likely to use certified coaches to plan and implement their strength and conditioning programs. Most programs included dynamic warm-ups and cool-downs, plyometrics, agility training, speed training, and conditioning, and most programs were conducted 3 d·wk(-1) (76%) for sessions lasting between 30 and 59 minutes (63%). Compared with their female counterparts, male athletes were more likely to have required training, participate in strength training year round, and train using more sessions per week. This study provides additional information related to the practice of strength and conditioning in a sample of high school athletic teams.

  6. Context, accuracy, and level of inclusion of nature of science concepts in current high school physics textbooks

    Alshamrani, Saeed Mohammed

    To improve K-12 students' images of the nature of science (NOS) through science textbooks, two issues must be addressed: (a) the level of NOS that ought to be included in science textbooks and (b) the treatment of this level in those textbooks. Science educators achieved a consensus level of agreement regarding what NOS aspects should be taught for K-12 science learners; however, there is a need for more clarification regarding the actual treatment of NOS in science textbooks. The purpose of this study is to investigate the NOS inclusion in high school physics textbooks. To be specific, this study examines the included NOS aspects, the frequency of NOS inclusion, the contexts exist for NOS inclusion, and the accuracy of NOS inclusion. This study utilized 12 science education studies to develop the Master Aspects of Nature of Science [MA-NOS] which includes 12 NOS aspects that ought to be included in K-12 science curriculum. The analyzed textbooks in this study are seven textbooks identified by The American Institute of Physics as the most widely used high school physics textbooks in the United States in 2005. These textbooks were used in teaching five academic levels: (a) Regular First-Year Physics, (b) Physics for Non-Science Students, (c) Honors Physics, (d) AP-B Physics, and (e) AP-C Physics. The researcher selected exclusively physics textbooks because physics is his main interest. To facilitate the content analysis of the selected textbooks, the study developed The Collection Data Coding Guide which includes six parts describing the MA-NOS aspects and the process of identifying and collecting data. For each NOS aspect, a description and one or more selected ideal indicators were provided to facilitate data collecting and judging the accuracy of NOS inclusion. This coding guide was reviewed for its content validity by two science educators who specialize in NOS. However, two types of reliability were conducted to identify the consistency of selecting NOS units

    Full Text Available Introduction: A growing body of empirical research documents a significant co-occurrence of suicide attempts and interpersonal violence among youth. However, the potential role of early alcohol use initiation and current heavy alcohol use as correlates of this comorbidity has not been examined in a nationally representative sample of high school students.Methods: We based our analyses on cross-sectional data from the 2009 Youth Risk Behavior Survey, which includes a nationally representative sample (n=16,410 of high school students in grades 9 through 12 in the United States. Multinomial logistic regression analyses were conducted to test the associations between measures of alcohol use (early alcohol use initiation and heavy drinking and comorbid suicidal and violent behavior while controlling for potential confounders.Results: Among high school students, 3.6% reported comorbid physical fighting and suicide attempt in the past year. Early alcohol use (prior to age 13 and heavy drinking (5 or more drinks in a row were strongly associated with comorbid reports of physical fighting and suicide attempts (Adj. odds ratio [OR]=3.12; 95% confidence interval [CI]:2.49-3.89 and (Adj. OR=3.45; 95%CI:2.63-4.52.Conclusion: These findings underscore the importance of both early alcohol use initiation and heavy drinking as statistically significant correlates of comorbid fighting and suicide attempts among youth. While future research is needed to determine the temporal ordering between problem drinking and violent or suicidal behaviors, existing prevention programs may benefit from including components aimed at reducing and delaying alcohol use.

  10. The Coverage of Human Evolution in High School Biology Textbooks in the 20th Century and in Current State Science Standards

    Science.gov (United States)

    Skoog, Gerald

    Efforts to eliminate or neutralize the coverage of evolution in high school biology textbooks in the United States have persisted with varying degrees of intensity and success since the 1920s. In particular, the coverage of human evolution has been impacted by these efforts. Evidence of the success of these efforts can be chronicled by the emphasis given to human evolution in secondary biology textbooks historically and in the current state science standards. Prior to the 1960s, biology textbooks provided little emphasis to human evolution. In the 1970s and early 1980s textbooks reduced the coverage of human evolution. However, in the 1990s the coverage became quite comprehensive again. In 2004, the state science frameworks of only three states had standards concerned with human evolution.

    How to teach writing courses have become troubled by the majority of junior high school language teacher cur-rently a major problem, and this situation is even more prominent in rural junior high school. New Curriculum requirements:Students should be close to the actual teaching of writing, so that students easy to write, ask students to tell the truth, the truth, the truth, do not tell lies, empty words, and clichés. How can we do it? For many problems in terms of students' writing, com-bined with years of teaching experience, I believe that rural junior high school teaching writing must recognize the new situ-ation and start to mobilize the enthusiasm of the students' writing from the culture interest in writing, focusing on student life and practice reading accumulation, the use of flexible composition assessment methods in order to effectively improve the level of writing.%如何上好写作课已成为当前困扰广大初中语文老师的一大难题,而这种情况在农村初中更是突出。新课标要求:写作教学要贴近学生实际,让学生易于动笔,要求学生说真话、实话、心里话,不说假话、空话、套话。如何才能做到呢?针对学生写作方面存在的诸多问题,结合多年来的教学实践,笔者认为,农村初中作文教学必须认清新形势,从培养写作兴趣入手来调动学生的写作积极性,注重学生的生活实践和阅读积累,运用灵活多样的作文评改方式,才能切实提高作文水平。

  17. Dual Campus High School

    2013-04-01

    Full Text Available September 2010 witnessed the opening of the first complete dual campus high school in Alberta. Catholic Central High School, which had been in existence since 1967 in one building, now offered courses to students on two campuses. The “dual campus” philosophy was adopted so as to ensure maximum program flexibility for students. The philosophy, however, was destined to affect student engagement and staff efficacy as the change in organizational structure, campus locations, and course availability was dramatic. Changing school organizational structure also had the potential of affecting student achievement. A mixed-methods study utilizing engagement surveys, efficacy scales, and interviews with students and teachers was used to ascertain the degree of impact. The results of the study showed that minimal impact occurred to levels of student engagement, minor negative impact to staff efficacy, and a slight increase to student achievement results.

    Research misconduct has become an important matter of concern in the scientific community. The extent to which such behavior occurs early in science education has received little attention. In the current study, using the web-based data collection program REDCap, we obtained responses to an anonymous and voluntary survey about science fair from 65 high school students who recently competed in the Dallas Regional Science and Engineering Fair and from 237 STEM-track, post-high school students (undergraduates, 1st year medical students, and 1st year biomedical graduate students) doing research at UT Southwestern Medical Center. Of the post-high school students, 24% had competed in science fair during their high school education. Science fair experience was similar overall for the local cohort of Dallas regional students and the more diverse state/national cohort of post-high school students. Only one student out of 122 reported research misconduct, in his case making up the data. Unexpectedly, post-high school students who did not participate in science fair anticipated that carrying out science fair would be much more difficult than actually was the case, and 22% of the post-high school students anticipated that science fair participants would resort to research misconduct to overcome obstacles. No gender-based differences between students' science fair experiences or expectations were evident.

    2005-01-01

    The secondary particle focusing horn for the AGS neutrino experiment proposal is a high current and high current density device. The peak current of horn is 300 kA. At the smallest area of horn, the current density is near 8 kA/mm2. At very high current density, a few kA/mm2, the electromigration phenomena will occur. Momentum transfer between electrons and metal atoms at high current density causes electromigration. The reliability and lifetime of focusing horn can be severely reduced by electromigration. In this paper, we discuss issues such as device reliability model, incubation time of electromigration, and lifetime of horn.

An account of the 1998 winners appeared in last January's issue (5), providing the basis for another convenient resource file. Water droplets on a surface of Magic Sand. For many students electrochemistry is among the least favorite of the topics included in first- or second-year high school chemistry - despite the many interesting applications that students encounter every day. There are many reasons why students find the topic difficult, but misconceptions about current flow seem to present the largest obstacle to developing a conceptual understanding of electrochemical processes. Two university faculty members and a high school teacher, Huddle, White, and Rogers, have developed a teaching model to help students confront and overcome their misconceptions (pp 104-110). They have conducted studies of the impact of the model's use on student learning in both high school and introductory college chemistry courses. Particularly encouraging were the learning gains made by students with weak academic backgrounds. An action research project focused on student perspectives of small-group learning is described by Towns, Kreke, and Fields (pp 111-119). Although the project involved upper-division undergraduate university students, action research can be useful to any chemistry teacher who wishes to systematically examine and improve instructional methods and strategies. This article may be especially interesting to readers who frequently employ small-group learning techniques in their classroom. Advances in the technology of multimedia delivery are having an impact on the format in which new JCE Software releases are available. In particular, CD-ROM and Internet browsers are becoming increasingly important as the medium and method of access respectively. To better understand what is

Lawrence and Stuart Fishelson, p 1216A Author Recognition A new program has been instituted to recognize high school teachers who are authors or coauthors of manuscripts published in the Journal. In May, letters were sent to teachers who wrote articles published in JCE beginning with Volume 74 (1997). If you were an author, you should have received a letter from us in late May or early June stating that your high school principal has been sent a Certificate of High School Author Recognition to be presented to you at a suitable occasion. Because the letters were sent late in the school year, you may not see the certificate until fall, or you may not receive your letter until then if we had only your school address. If you have authored or coauthored an article published in JCE and did not receive a letter, please contact me using the information about the Secondary School Chemistry Editor appearing on the Information Page in this issue. Syllabus Swap In the August issue, this column contained an invitation to exchange high school syllabi. The day after my copy of the August issue arrived, I received an email from a teacher indicating an interest in participating in an exchange. If you are interested, check the August "Especially for High School Chemistry Teachers" column for a brief discussion of the informal exchange program, or contact me. Research Conducted by High School Students In his June 1999 editorial "Learning Is a Do-It-Yourself Activity", p 725, John Moore wrote about the need to engage students actively in the learning process.

    Full Text Available The information technology revolution has influenced education greatly. All participants in the educational process should be informed about the latest teaching and information technology on a regular basis, and should prepare and teach the younger generation to use it. An important role in spreading information literacy is played by libraries and librarians in frame of the subject of Library Information Skills tought in schools. The research, as presented in continuation, was performed by means of a questionnaire answered by students of Gimnazija Poljane (Poljane High School. The purpose of the research was to find out how well the students are prepared to use information technology (IT, which types of materials (traditional : up-to-date electronical they tend to use more, how they gather information. The results have shown that boys can handle the information technology better than girls. Boys use electronic sources more frequently, they visit the school library more frequently, more of them searching for information which is not directly related to their lessons. Girls use traditional materials and search for information related to their lessons. However, the majority of students search for library material on their own or with the help of a librarian rather than use information technology.

    Full Text Available This article presents the results of a study of mathematical fluency in high school students. We provide a definition of mathematical fluency and illustrate the relevance of the research by presenting an overview of studies examining mathematical fluency development and its relationship with success in mathematical disciplines. A computerized test “Problem Verification Task” (Tosto et al., 2013 was administered to 692 high school students from one public secondary school (grades 9/10/11: n = 336/210/146 in the Moscow region. The stimuli consisted of 48 elementary arithmetic equations along with answer options. To indicate a correct answer, participants were instructed to press the corresponding key on the keyboard as quickly as possible. Two-way ANOVA was used to estimate grade and sex similarities and differences in mathematical fluency at the high school level. The current study has two primary findings: (1 students differed in math fluency across grades, and (2 there were no sex differences in mathematical fluency at the high school level. ANOVA exhibited significant differences in mathematical fluency among all three groups of students at grades 9, 10 and 11 with a 19% effect size. These results may be associated with the accumulating effects of the educational process: high school students in each subsequent year of schooling demonstrate a higher level of mathematical fluency on average compared to the previous year. At the same time, we observed no sex differences in mathematical fluency at the high school level. The results are discussed in terms of educational effects.

    Recently the need to manage food allergies in schools has been growing. This study aimed to examine the current status of managing food allergies in schools in Seoul, Korea. A questionnaire survey was conducted in cooperation with the School Dietician Association during April 2009. Among the participating 154 schools, a total of 109 (71%) were determining students' food allergy status through parental surveys based on self-reported food allergies. A total of 72 (47%) had experienced student visits to a school health room due to food allergies within one year before the survey. Over 80 percent of the schools relied on self-care only without any school-wide measures for food allergies in place. Among the 890 menu items most frequently served in school lunch programs, a total of 664 (75%) were found to contain more than one food allergen. It is highly suggested that preventive plans and treatment measures should be established to manage food allergies in schools.

    176A-176B. Addressing Some Specialized Interests As in any issue of the Journal, there are several articles that are not designated with the secondary school mark (?) but are likely to be of interest to some high school teachers. For example, if you are interested in staying abreast of educational applications of computational chemistry, the articles on pages 199-221 will be among those you will wish to examine even though the focus is on meeting the learning needs of college students. For those with an interest in electronics, there are several articles on pages 252-262, on building on modifying useful devices. Among the topics: building a digital monitor for analyzing spectrophotometer signals, building a digital interface for a graphing calculator, and using an inexpensive commercial analog-to-digital converter.

  11. Credentialing high school psychology teachers.

    Weaver, Kenneth A

    2014-09-01

    The National Standards for High School Psychology Curricula (American Psychological Association, 2013b) require a teacher with considerable psychology content knowledge to teach high school psychology courses effectively. In this study, I examined the initial teaching credential requirements for high school psychology teachers in the 50 states plus the District of Columbia. Thirty-four states (the District of Columbia is included as a state) require the social studies credential to teach high school psychology. An analysis of the items on standardized tests used by states to validate the content knowledge required to teach social studies indicates little or no presence of psychology, a reflection of psychology's meager presence in the social studies teacher preparation curricula. Thus, new teachers with the social studies teaching credential are not prepared to teach high school psychology according to the National Standards. Approval of The College, Career, and Civic Life (C3) Framework for Social Studies State Standards: Guidance for Enhancing the Rigor of K-12 Civics, Economics, Geography, and History (National Council for the Social Studies, 2013) presents an opportunity to advocate for establishing a psychology credential in the 34 states.

    Full Text Available About 100 teachers participated in a study and helped to understand how new reforms are faced by those who work in the field, in the particular case of the discipline of geography. The study that was done with geography teachers after 10 years of national curriculum revealed many gaps in terms of what teachers are expected to do. Only recently, some legislation has been issued to regulate the kind of training teachers do as they progress in their teaching careers. The national curriculum for basic education is a huge step in terms of being a part of the world agenda in what concerns a modern teaching and a new vision of what schools should prepare students to, but the instruments of that change (teachers have been neglected.

  13. SCHOOLS AND CYBERBULLYING: PROBLEM PERCEPTION, CURRENT ACTIONS AND FUTURE NEEDS

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Cyberbullying is a common phenomenon amongst young people. It exhibits many similarities to traditional school bullying, with a potentially serious impact on the mental health and school functioning of victims. For this reason, action by schools is often recommended. The aim of this article is to provide a better picture of what schools are currently doing to address cyberbullying and of what schools will need to continue doing so in the future. An online survey was conducted among staff members of 309 primary and secondary schools in Flanders, which is the Dutch speaking part of Belgium. The questionnaire measured the schools’ experiences with cyberbullying and their perceived responsibility and efficacy in dealing with this issue as well as their concrete preventive, detective, and reactive actions. The results indicate that, although most schools are aware of relatively few cases of cyberbullying, they do consider cyberbullying to be a problem. Many schools consider it their duty to inform students about cyberbullying and to help find solutions to cyberbullying incidents involving students, even if they take place away from the school grounds or outside school hours. Although most schools organize concrete actions with regard to cyberbullying, they often seem uncertain about the appropriateness and effectiveness of their actions. They would welcome evidence-based intervention programmes that would appeal to their students.

    Chemistry and the Environment This issue contains more than 20 articles relating to the environment. Several articles of potential interest are indicated in the Table of Contents with the SSC mark (). Others are not so indicated because they depict use of expensive instrumentation or costly procedures, but if you have an interest in environmental chemistry you may wish to examine all the environmentally related articles. While many of the articles, both marked and unmarked, are targeted to college-level environmental chemistry curricula or to introductory courses for non-major, the methods described in several could be readily adapted to high school chemistry courses. One article likely to be of interest to teachers is found in News from Online, pp 1608-1609. The author explains how to use the U.S. Environment Protection Agency's EnviroMapper Web site to view and query environmental information. She mentioned finding a hazardous waste handler located near her home, so I decided to check the area near my home. I quickly located a natural gas salt dome storage facility marked on the map and, with a few more mouse clicks, I found information that included status of compliance with regulations, amounts of each compound released to the air in tons per year, and how to contact the corporation owning the site. Email and Web site addresses were included for the convenience of anyone wishing to contact the corporation. Students could learn a great deal about where they live that is relevant to chemistry by using the EPA site. Additional Web sites dealing with environmental issues and chemistry are cited in the sidebar at the bottom of p 1609. Among the articles that could be adapted to an advanced high school chemistry class or possibly even to an introductory class is one titled Bridge of Mandolin County (pp 1671-1672). It describes a case-study strategy similar to the scenarios used in ChemStudy. Students analyze information from various sources, including laboratory

    Earth science provides an ideal opportunity to integrate authentic research into middle and high school curricula by providing a context for teaching scientific content, promoting a sense of intrigue through the inquiry process, and sharpening skills needed for future scientific endeavors. The University of New Hampshire's offerings as part of the Transforming Earth System Science Education (TESSE) project provide for the professional development of in-service and pre-service middle and high school science teachers. A centerpiece of the TESSE program is an entry-level accelerated course in Earth Systems Science (Earth System Science for Teachers, ESST-1). Participants in the ESST-1 course include current and prospective teachers wishing to improve their Earth science content background or those interested in updating their traditional content background to include a systems approach. Time scale and system interactions significant in the Earth System are introduced through authentic research conducted during field trips, research experiences and working with long-term datasets. Teachers are trained in keeping a field notebook, making field observations, and drawing conclusions based on this evidence. Combining these techniques with digital photography, teachers document evidence of Earth system processes and their associated timescales, presenting their findings in a peer-group poster session. Teachers also participate in research-based field trips to the local estuary and a wetland research site. During the following school year, the teachers are paired with science graduate fellows to integrate inquiry- based research with existing curricula. These classroom collaborations include measurement techniques, process skills and methods of communicating evidence learned during the summer institute that are then incorporated into the classroom activities. In addition to effecting change at the curriculum-development level, the graduate fellows paired with the first

    Care to Share? An Informal Syllabus Exchange A recent email message from Thomas Shiland, who teaches at Saratoga Springs Senior High School, noted that the process of revising the high school chemistry syllabus is underway in New York State. He expressed a strong interest in helping construct a chemistry syllabus that represents the best thinking about appropriate content. He wondered if it would be possible to develop a way in which different secondary chemistry syllabi could easily be exchanged. It is likely that readers from other states and countries are involved in a similar process and might also be interested in exchanging syllabi. Many states do not use the term syllabus to describe their guiding curricular document for chemistry but rather refer to it as a framework or as guidelines. In most cases, the document includes a list of key ideas or topics, performance indicators, and the major understandings associated with each key idea. Such documents would be appropriate for exchange among those of you involved in the revision process. If you are interested in arranging an exchange please contact me by email at j.e.howell@usm.edu or by mail at J. E. Howell, Box 5043, USM, Hattiesburg, MS39406-5043, USA.

McKean, p 916 * A pHorseshoe, by Roger Plumsky, p 935 National Conferences in Your Part of the Country For the past several months, considerable space in this column has been devoted to forthcoming national conferences and conventions and to highlights of conferences past. For some of us, location is fairly unimportant; but for most of us travel costs and time are both factors to consider when choosing a conference. The community of high school chemistry teachers is favored by the number of national conventions and conferences that are held each year in different locations. In 1999, for example, the spring National Meeting of the American Chemical Society was in Anaheim and the National Science Teachers Association National Convention was in Boston. This summer CHEMED '99 will be held in Fairfield, CT, August 1-5, and the fall National ACS Meeting will be in New Orleans. Teachers from the mid-South especially should consider attending the High School Program at New Orleans, described below by Lillie Tucker Akin, Chairperson of the Division's High School Program Committee. The event will be held on Sunday to minimize conflicts with the beginning of the school year. JCE at CHEMED '99 Stop by the JCE booth at CHEMED '99 in the exhibits area to learn more about the wide array of print and nonprint resources you can use in your classroom and laboratory. Members of the editorial staff will be on hand to talk with you.

    Adolescents transitioning to high school may be at greater risk of depression and suicide if they are victims of bullying behavior. This study explored sex differences in bullying victimization (physical, verbal/social, and cyberbullying) and the impact on depressive symptoms and suicidal behaviors in ninth-grade students ( N = 233). Females reported significantly more verbal/social and cyberbullying than male students. There were no significant sex differences in physical bullying; male students who reported physical bullying victimization were more likely to experience depressive symptoms. Verbal/social bullying predicted depressive symptoms in males and females. Females who reported being victims of cyberbullying were more likely to report depressive symptoms, suicide ideation, and suicide attempts. Eighteen students reported suicide attempts, and each also experienced verbal/social bullying. School nurses are positioned to reach out to transitioning students, screen for mental health issues, provide a safe place to talk about bullying experiences, and promote positive mental health.

    A technique has been developed which allows the simultaneous determination of most of the important parameters of a high current superconductor. The critical current, propagation velocity, normal state resistivity, magnetoresistance, and enthalpy are determined as a function of current and applied field. The measurements are made on non-inductive samples which simulate conditions in full scale magnets. For wide, braided conductors the propagation velocity was found to vary approximately quadratically with current in the 2 to 5 kA region. A number of conductors have been tested including some Nb/sub 3/Sn braids which have critical currents in excess of 10 kA at 5 T, 4.2 K.

    Reports from the French Ministry of Education warn of a decrease in the use of school food services, especially in sensitive urban areas. They also suggest that this decline has led to cases of malnutrition. This article describes the characteristics of the current supply of school meals and measures the evolution of demand observed between 1992 and 1996 in relation to the economic situation of students' families. The study was carried out in 3 departments in France: Doubs, Herault, and Val de Marne. The administrators of all public and private middle and high schools in the 3 departments received a questionnaire asking them to describe the services offered in their cafeterias and to provide the corresponding statistical and accounting data. External food services near the schools were also taken into account. Seventy-nine percent of schools responded to the survey. Concerning the services offered, 91% of schools have their own cafeterias, of which 81% are managed by the schools. Concerning the evolution of utilisation, a significant decrease in the number of meals served in seen in middle schools. On the other hand, high schools have observed stable utilisation. The positive changes in utilisation are linked, in middle schools, to characteristics of the schools' internal food services (self-service, choice of main courses, modulation of seats). In high schools, positive changes in the utilisation of school services are linked to the lack of external food services near the schools. As middle schools and high schools control the logistics and management of food services offered to students, they are potentially in a position to influence a policy on this issue. The evolution in utilisation is very different among departments and between middle and high schools. While economic precariousness has a negative structural effect on utilisation, it doesn't seem to be a major factor in the evolution of the decrease observed over the past few years.

    The development of high current positive and negative ion sources is an essential issue for the next generation of high current linear accelerators. Especially, the design of the European Spallation Source facility (ESS) and the International Fusion Material Irradiation Test Facility (IFMIF) have increased the significance of high brightness hydrogen and deuterium sources. As an example, for the ESS facility, two H{sup -}-sources each delivering a 70 mA H{sup -}-beam in 1.45 ms pulses at a repetition rate of 50 Hz are necessary. A low emittance is another important prerequisite. The source must operate, while meeting the performance requirements, with a constancy and reliability over an acceptable period of time. The present paper summarizes the progress achieved in ion sources development of intense, single charge, positive and negative ion beams. (author) 16 figs., 7 refs.

    Many places have carried out reforms about the entrance examination for senior high schools in China currently,and people have different views about this.This paper thinks we should clarify four focus questions which closely interconnected with reformation before research reformation of the examination: test or not test,what to test,how to test and how to recruit students.The reformation of the examination will obtain good results only if the four questions are clarified.First,the evaluation and filtering capabilities of graduation and entering a higher school determine that the examination not be canceled at this stage in junior high schools.Secondly,the setting of examination subjects must be able to promote the development of students' overall quality,and the degree of difficulty about examination content must be reasonable.Thirdly,it's not suitable for using the model of the open-book examination,the comprehensive examination of arts and the comprehensive examination of science in elementary and junior high schools in order to prevent the early formation of the concept about dividing of art and science which affects the comprehensiveness of the basic knowledge.Finally,no matter what method of recruiting we choose,we should pay attention to the fairness.%当前我国许多地方都在进行中考改革,人们对于这些改革的意见不一,评价也不一。要研究中考改革,必须厘清下面四个与改革密切相关的焦点问题:考不考?考什么?怎样考?怎样招?只有厘清了这四个问题,中考改革才能取得实效。首先,初中阶段的毕业和升学所需要的评价与筛选功能决定了现阶段中考不能取消;其次,考试科目的设置一定要能够促进学生全面素质的发展,考试内容的难易度设计一定要合理;再次,在中小学阶段不适合采用开卷考试以及文科综合和理科综合的考试方式,以防止过早地形成文理分科现象,从而影响学生基础知识的全

For each article I have highlighted the major point(s) and the reasons it may be of interest to high school teachers. First, the article "The NSF 'Systemic' Projects- A New Tradition" (G. M. Barrow, p 158) is a commentary on changes in post-secondary introductory chemistry courses in which a distinction is drawn between information management and individual understanding. The author is of the opinion that most students expect the former and that the NSF-funded systemic projects "will thrive only if they are consistent with their information-management mission". Three individuals provided responses to the commentary from their perspective. Has a student asked you why mercury is a liquid, or why gold is the most electronegative metal?

In order to get the anticipated performance level of ampere-class currents, many technological barriers are yet to be broken. BNL's Collider-Accelerator Department is pursuing some of these technologies for its electron cooling of RHIC application, as well as a possible future electron-hadron collider. We will describe work on CW, high-current and high-brightness electron beams. This will include a description of a superconducting, laser-photocathode RF gun and an accelerator cavity capable of producing low emittance (about 1 micron rms normalized) one nano-Coulomb bunches at currents of the order of one ampere average.

    Writing Across the Curriculum The notion that student learning is enhanced through writing is widely accepted at all educational levels if the product is fairly assessed and the learner is provided with feedback. Finding the time to critically evaluate student papers is difficult at best and competes with time needed to prepare laboratory investigations. A few weeks ago a teacher who has extensive extracurricular responsibilities that include extensive interaction with parents and community members shared with me his frustration in not being able to grade written reports. This teacher is the head football coach at his school, but many readers experience the same difficulties due to a variety of duties. There are no easy or completely satisfying answers to this problem, but this issue contains an account of a successful approach (Writing in Chemistry: An Effective Learning Tool, pp 1399-1403). Although they are based on experience in college courses, several ideas described in the article could be applied in high school chemistry courses. In another article, the author of Precise Writing for a Precise Science (pp 1407-1408) identifies 20 examples of familiar, but incorrect, grammatical constructions and explains how to phrase each one correctly. Chemical Education Research: Improving Chemistry Learning The results from research on how students learn have greatly increased our understanding of cognition in recent years. However, the results are often published in the science education research literature and are not readily accessible to the classroom teacher. Additionally, the research reports are couched in specialized terminology. This issue contains a Viewpoints article (pp 1353-1361) that bridges the gap between research results and classroom application. It was written by two veteran chemical educators, Dudley Herron and Susan Nurrenbern.

    Cigarette smoking in adolescent is a significant public health problem, leading to the risk of addiction, morbidity, and mortality in the long term. This study determined the prevalence and correlates of current smoking among adolescent school children. A nationwide school-based survey among 25 507 students between Forms 1 to 5 (aged 12-17) was conducted using a 2-stage cluster sampling design. The prevalence of current smoking was 11.5%. Multivariable logistic regression analysis revealed that current smoking was significantly associated with males (adjusted odds ratio [aOR] = 3.25; 95% confidence interval [CI] = 1.87, 4.98), current drinking (aOR = 2.34; 95% CI = 1.46, 3.74), drug used (aOR = 2.97; 95% CI = 1.24, 7.11), and being bullied (aOR = 1.41; 95% CI = 1.00, 1.98) at least once in the past 12 months. Smoking is associated with several behaviors that pose risks to adolescents, such as social issues and smoking-related health problems. Thus, early and integrated prevention programs that address multiple risk behaviors simultaneously are required.

    Optimization of machine operation, including plasma position control, density control and especially feedback control on multiple magnetohydrodynamic modes, has led RFX-mod to operate reliably at 1.5 MA, the highest current ever achieved on a reversed field pinch (RFP). At high current and low density the magnetic topology spontaneously self-organizes in an Ohmical helical symmetry, with the new magnetic axis helically twisting around the geometrical axis of the torus. The separatrix of the island disappears leaving a wide and symmetric thermal structure with large gradients in the electron temperature profile. The new topology still displays an intermittent nature but its overall presence has reached 85% of the current flat-top period. The large gradients in the electron temperature profile appear to be marginal for the destabilization of ion temperature gradient modes on the assumption that ions and electrons have the same gradients. There are indications that higher currents could provide the conditions under which to prove the existence of a true helical equilibrium as the standard RFP configuration.

    assigned as a take-home activity. JCE Classroom Activity #15, "Liver and Onions: DNA Extraction from Animal and Plant Tissues" (p 400A, March 1999) also integrates chemical and biological concepts. The JCE Software videotape HIV-1 Protease: An Enzyme at Work is another useful resource. It can be used in any classroom where kinetics, catalysis, proteins, or enzymes are discussed. Information about JCE Software products can be found in recent issues of the Journal or by accessing JCE Online (http://jchemed.chem.wisc.edu). Because most high school students complete at least one year of biology before enrolling in chemistry, developing the connections between biology and chemistry can be especially productive. Connections between chemistry and biology often seem to be more real to students than do many of the phenomena we cite as applications. For example, students often are not able to make the connection between the excitation of electrons to produce electromagnetic radiation and anything that is personally relevant. The light given off by sodium or mercury vapor lights provides a common example of relating atomic emission to a useful process, but many students do not seem to find that particularly interesting. The need to make a connection between biology and chemistry becomes especially meaningful to students when the chemical change occurs within the human body. As an example, the interaction of emitted electromagnetic radiation with human cells to cause well-tanned skin seems more relevant to a greater number of students than the color of lights in a parking lot. This issue contains an article that describes a useful application of light to kill cancer cells through use of photosensitizers (p 592). The process of photodynamic therapy (PDT) provides another example that could help students make a connection between the emission of electromagnetic radiation and the challenge of killing cancer cells without harming healthy cells. Certainly this example is not a magic

  11. High-temperature superconducting current leads

    Hull, J. R.

    1992-07-01

    The use of high-temperature superconductors (HTSs) for current leads to deliver power to devices at liquid helium temperature is near commercial realization. The use of HTSs in this application has the potential to reduce refrigeration requirements and helium boiloff to values significantly lower than the theoretical best achievable with conventional leads. Considerable advantage is achieved by operating these leads with an intermediate temperature heat sink. The HTS part of the lead can be made from pressed and sintered powder. Powder-in-tube fabrication is also possible, however, the normal metal part of the lead acts as a thermal short and cannot provide much stabilization without increasing the refrigeration required. Lead stability favors designs with low current density. Such leads can be manufactured with today's technology, and lower refrigeration results from the same allowable burnout time. Higher current densities result in lower boiloff for the same lead length, but bumout times can be very short. In comparing experiment to theory, the density of helium vapor needs to be accounted for in calculating the expected boiloff. For very low-loss leads, two-dimensional heat transfer and the state of the dewar near the leads may play a dominant role in lead performance.

    Secondary School Feature Articles * Amino Acid Wordsearch, by Terry L. Helser, p 495. Games, Puzzles, and Humor In honor of April Fools' Day this issue contains 22 pages devoted to games and puzzles that can be used to teach aspects of chemistry. Most are designed for high school and first-year college students. The lead article, p 481, contains an annotated bibliography of chemistry games, complete with a vendor list. Many of the annotated games must be purchased, but the other articles that follow in this issue describe some games and puzzles that require minimal preparation using a word processor and readily available materials. Actually, JCE has a long tradition of publishing games and puzzles for chemistry teachers and their students. Read the letter by Helser and the Editor's response, p 468, for some recent background. Not having counted articles over past years, I became curious and turned to the online index, accessed by way of http://jchemed.chem.wisc.edu/. Because I wanted to search the entire 75-year life of the Journal, I searched titles for the words "game", "puzzle", and "humor" and obtained a total of 85 hits from the three searches. After eliminating titles of articles that were not applicable, I found that at least 25 games, 48 puzzles, and 5 humor articles have appeared during the past 75 years. At an average of one per year, the JCE editors hardly can be accused of frivolity, but game, puzzle, and humor articles have been published. The term "game" did not appear in any titles during 1945-1970, "puzzle" did not appear from 1927 to 1953, and there was no mention of humor (in the titles) prior to 1974. What appears to be the earliest article (1929) about a game was authored by an undergraduate student at the University of Colorado (1). It was titled "Chemical Bank", and the game pieces were tokens cut from cork stoppers. Wire hooks were inserted in the side of the token to represent valence electrons available for bonding. Carbon contained 4 hooks

    2016-12-01

    Current literature reports that the astronomy education is motivating and interesting for basic education, but the content suggested by the national curriculum guidelines do not seem to attract students and teachers in order to transcend the discipline of Science in the elementary School or Physics in High School. By applying a questionnaire to 80 students of High School and participants of Brazilian Olympiad of Astronomy and Astronautics of two schools of São Paulo state, we obtained results that indicate that astronomy topics that really motivate students are topics linked to science fiction and current research, which are the subject of extensive media release and have a strong interdisciplinary character. At the end of the work we suggest a new context for astronomy education, by inserting topics combined with other areas of knowledge to what we call “interdisciplinary astrophysics teaching”.

  8. Current trends in high temperature design

    Energy Technology Data Exchange (ETDEWEB)

    Marriott, D.L. (Illinois Univ., Urbana, IL (United States). Dept. of Mechanical Engineering)

    1992-01-01

    A review of high temperature design guidelines has been carried out in preparation for designing a solar storage module for the Freedom Spacelab. Three major guidelines, N47, R5 and RCC-MR form the basis of the survey. The main issues with current, mature design in the power industry appear to be adequately covered by these guidelines. A significant finding is that long established models of material damage have survived the test of time very well. A new design regime referred to as Very High Temperature Design (VHTD) is identified. The characteristics of this regime are changing material properties which require some changes in philosophy in drafting of future codes, particularly in regard to definitions of yield strengths and other design allowables. Finally, there is some discussion of the more general use of the stress/strain plane, e.g. isochronous curves, for representation of very complex material constitutive behaviour. A concept called the 'Relaxation Locus', which summarizes essential local constrained component behavior, is introduced and its application to high temperature design problems is discussed briefly.

    Kumar, Sarvesh; Mandal, A.

    2016-02-01

    The high current injector (HCI) provides intense ion beams of high charge state using a high temperature superconducting ECR ion source. The ion beam is accelerated upto a final energy of 1.8 MeV/u due to an electrostatic potential, a radio frequency quadrupole (RFQ) and a drift tube linac (DTL). The ion beam has to be transported to superconducting LINAC which is around 50 m away from DTL. This section is termed as high energy beam transport section (HEBT) and is used to match the beam both in transverse and longitudinal phase space to the entrance of LINAC. The HEBT section is made up of four 90 deg. achromatic bends and interconnecting magnetic quadrupole triplets. Two RF bunchers have been used for longitudinal phase matching to the LINAC. The ion optical design of HEBT section has been simulated using different beam dynamics codes like TRACEWIN, GICOSY and TRACE 3D. The field computation code OPERA 3D has been utilized for hardware design of all the magnets. All the dipole and quadrupole magnets have been field mapped and their test results such as edge angles measurements, homogeneity and harmonic analysis etc. are reported. The whole design of HEBT section has been performed such that the most of the beam optical components share same hardware design and there is ample space for beam diagnostics as per geometry of the building. Many combination of achromatic bends have been simulated to transport the beam in HEBT section but finally the four 90 deg. achromatic bend configuration is found to be the best satisfying all the geometrical constraints with simplified beam tuning process in real time.

    for You? The end of the school year is approaching quickly. In previous years, several readers have submitted manuscripts soon after the end of the school year, while ideas were fresh in their mind and there was relief from the demands of daily classes. If you have an idea for an article, I encourage you to think about writing as soon as the school term ends. I can probably guess what you are saying, "I don't have anything that readers would be interested in." This is a common reaction, to which we frequently respond by reminding high school teachers that this is "your journal" and the only way to ensure that topics of interest to you are considered or published is by your active participation. In this presidential election year I am reminded of the familiar sentiment, "I voted in the election, so I have earned the right to complain about the politicians." I do not wish to encourage complaining, but there is a relevant correlation. By submitting manuscripts to the Journal, you are ensuring that you will continue to get your money's worth because it will include topics of interest to you. When considering a submission, many prospective authors are overwhelmed at the thought of preparing a complete manuscript. Don't let that stop you. If you have an idea, an outline, or a rough draft, any of the feature editors or I would be happy to discuss it with you. This one-on-one interaction during the development process will help you express your ideas more effectively. Many teachers across the country who are faced with similar situations and problems each day would benefit from an article discussing innovative teaching strategies or a new way to look at principles we teach every year. As you begin to formulate your ideas, I would like to emphasize five features whose editors are fellow teachers: JCE Classroom Activities.

    2008-04-01

    During the inaugural year (2006-07) of the Academic Dental Careers Fellowship Program (ADCFP), 110 faculty members at ten different dental schools were interviewed by dental students who were participating as ADCFP fellows in this year-long program designed to introduce them to faculty roles and activities and help them gain an appreciation for the rewards and issues associated with academic life. The goals, format, and components of the ADCFP are described in a companion article in this issue of the Journal of Dental Education. One of the fellows' assignments during the ADCFP was to interview faculty at various academic ranks who had differing degrees of work emphasis in teaching, research, service/patient care, and administration. Sixty-nine (63 percent of the total) of these interviews were reviewed and analyzed by the authors, who were student fellows in the ADCFP during 2006-07. The purpose of these interviews was to provide the fellows with insight into the positive aspects and challenges in becoming and remaining a dental school faculty member. This aggregate perspective of the interviews conducted at ten dental schools highlights the motivations and challenges that confront a dentist during the process of choosing a career in academic dentistry and determining if dental education is a good fit for each individual who elects to pursue this pathway. Thematic analysis of the interviews revealed several factors consistently identified by faculty across the schools as being positive influences on the quality of the academic work environment and career satisfaction: mentorship and student interaction, opportunities for scholarship (research and discovery), job diversity, intellectual challenge, satisfaction with the nature of academic work, lifestyle/family compatibility, flexibility, lifelong learning, professional duty, and lab responsibility. A series of negative themes were also consistently identified: bureaucracy/administrative burdens and barriers, time

    A pediatrician is asked by her local school board to help them decide whether to discontinue their high school football program. She reviews the available evidence on the risks of football and finds it hopelessly contradictory. Some scholars claim that football is clearly more dangerous than other sports. Others suggest that the risks of football are comparable to other sports, such as lacrosse, ice hockey, or soccer. She finds very little data on the long-term sequelae of concussions. She sees claims that good coaching and a school culture that prioritizes the health of athletes over winning can reduce morbidity from sports injuries. In this paper, 3 experts also review the evidence about sports risks and discuss what is known and not known about the science and the ethics of high school football.

    2001-01-01

    The percentage of sexually experienced young persons in South Korea has increased and the age of first intercourse has lowered significantly. However, these marked changes in the sexual behavior of young people have been taking place when schools in the country still generally lack a realistic sex education program. Given this situation, the aim of this study is to gather student opinions on current school-based sex education in Korea. A self-administered questionnaire survey was conducted in Seoul, Incheon, and Kyunggi Province to assess the status and needs of high school sexuality education. Survey data was obtained from 1,160 senior high school students. In this study 68.8% of boys and 94.4% of girls had some school-based sex or sexuality education. The mean hours of sex education instruction of boys and girls were 2.29 and 3.39 hours respectively. There are several reasons for not being satisfied with sex education in schools. Lack of information was the first reason in all categories. About seventy-four percent of respondents felt that the sex education taught in schools did not cover the information that they want. The second reason was that there was no trained sex education teacher. Lack of materials, interactive teaching method, and time were the other reasons given. They advocated starting sex education in elementary school and covering all topics by the age-appropriate level. More than half supported that sex education should be made compulsory in schools.

  11. MACHINE PROTECTION FOR HIGH AVERAGE CURRENT LINACS

    Energy Technology Data Exchange (ETDEWEB)

    Jordan, Kevin; Allison, Trent; Evans, Richard; Coleman, James; Grippo, Albert

    2003-05-01

    A fully integrated Machine Protection System (MPS) is critical to efficient commissioning and safe operation of all high current accelerators. The Jefferson Lab FEL [1,2] has multiple electron beam paths and many different types of diagnostic insertion devices. The MPS [3] needs to monitor both the status of these devices and the magnet settings which define the beam path. The matrix of these devices and beam paths are programmed into gate arrays, the output of the matrix is an allowable maximum average power limit. This power limit is enforced by the drive laser for the photocathode gun. The Beam Loss Monitors (BLMs), RF status, and laser safety system status are also inputs to the control matrix. There are 8 Machine Modes (electron path) and 8 Beam Modes (average power limits) that define the safe operating limits for the FEL. Combinations outside of this matrix are unsafe and the beam is inhibited. The power limits range from no beam to 2 megawatts of electron beam power.

  13. Investigating high school teachers’ views on cram schools

    Directory of Open Access Journals (Sweden)

    Savaş Baştürk

    2010-07-01

    Full Text Available The university entrance examination plays an important role in Turkish society. To explain this importance, one can find several reasons sociological, political or economic, but if we compare the rate of enrolment in higher education in Turkey with that of some countries (e.g., according to Dagli, 2006: Canada, 88%; Belgium, 56%; France, 51%; Egypt, 20% and Turkey, 12.5% , we note that it is very close to meeting the needs of the people. The importance of entrance to university in Turkey is exacerbated and is increasing because of the insufficient number of free places in universities or in the alternative programs in higher education and providing access to a trade. This situation leads many parents and teachers to urge their children (or students to succeed in school and in competitions. Thus, age as students begin to prepare for the competition down to 15-16 years. Research (Baltas et al. 1988; Cuceloglu, 1993 show that, students spend virtually all their time working, they are under intense physiological pressure and unnecessary stress. As parents are concerned about the future of their children and want them to receive tutoring to increase their chances of success in the competition, it has created in Turkey while a system of preparation for competition. These are the centers of private tutoring, commonly called "Dershane" in Turkish. It is private, not mandatory, but of course under the control of the state. Their main objective is to prepare students for competitions. They also provide tutoring to struggling students in secondary education. Students attend classes at Dershane after school, weekend or evening. In this paper, we aimed at investigating high school teachers’ views on dershanes High school teachers, who experience negative or positive effects of dershanes in their mathematics teaching, are the first-hand information sources to determine the place of the cram school education in an education system similar to Turkey.

    Conventional approaches to thermal conductivity in itinerant systems neglect the contribution to thermal current due to interactions. We derive this contribution to the thermal current and show how it produces important corrections to the thermal conductivity in anisotropic superconductors. We discuss the possible relevance of these corrections for the interpretation of the thermal conductivity of anisotropic superconductors.

  16. The interactive impacts of high school gay-straight alliances (GSAs) on college student attitudes toward LGBT individuals: an investigation of high school characteristics.

    Science.gov (United States)

    Worthen, Meredith G F

    2014-01-01

    Although gay-straight alliances (GSAs) are becoming more popular in high schools across the U.S., empirical studies investigating GSAs and their impact are sparse. Utilizing a sample of college students drawn from a large Southern university (N = 805; 78% White; 61% female; average age 22), the current study investigates the ways that the presence of high school GSAs affect college student attitudes toward LGBT individuals and how these relationships may vary by high school GSA location (South vs. non-South), town type (rural/small town, suburban, large city), and high school student population size. Overall, results from the current study show that the presence of a GSA in high school is a robust positive predictor of supportive attitudes toward LGBT individuals, even when considering many control variables. Such results suggest that the presence of GSAs in high schools may have significant positive and potentially long-lasting effects on college students' attitudes toward LGBT individuals.

    Full Text Available The purpose of this study was to determine the discipline styles of high school teachers. The population of this research included students of 10rd grade at central high schools in Niğde. There were 789 students at these high schools in the educational term of 2006-2007. The sample of this study was randomly selected 334 students. The data of the research were collected with an inventory called “Teacher Discipline Style Inventory” developed by Tomal (1999, 2001. The questionnaire is based upon a model consisting of five-discipline styles: Enforcing, abdicating, supporting, compromising and negotiating. There are six questions for each discipline styles with a total number of thirty questions. The data were analysed using means and standard deviation. The results of the study indicated that high school teachers most frequently used negotiating discipline style and rarely used abdicating discipline style.

    1996-08-01

    The refrigeration loads of current leads for superconducting magnets can be significantly reduced by using high-temperature superconductor (HTS) leads. An HTS conductor type that is well suited for this application is a laminated sintered stack of HTS powder-in-tube (PIT) tapes. The superconducting elements are normally characterized by their manufacturer by measuring critical currents at 77 K in self field. Additional characterization, which correlates electrical performance at 77 K and at lower temperatures with applied magnetic fields, provides the current lead designer and conductor element manufacturer with critical information. For HTS conductor elements comprising a laminated and sintered stack of Bi-2223 PIT tapes having an alloyed Ag sheath, this characterization uses variable applied fields and operating temperatures.

    For a more detailed investigation of current induced domain wall movement in nanowires by spin torque effect, it is essential to have maximum control of the external experimental parameters, i.e. the current density and the wire temperature. Additional, to study the forces that act on the walls, it is desirable to perform experiments with DC currents large enough to move the domain walls. In this talk we present the realization of Permalloy nanowires which sustain current densities larger 4.10{sup 12} A/m{sup 2}. The wires are made from 20 nm thick Permalloy, evaporated on diamond, with a width of 1 {mu}m and a length of 25 {mu}m. While applying current densities beyond 10{sup 11} A/m{sup 2}, we observe ohmic heating of the wires, which causes annealing effects. This effect can be used to improve the specific resistance of the wire near to the values of bulk material. The experiments are performed under HV conditions to prevent oxidation and cooling with liquid nitrogen is necessary for heat dissipation. The temperature of the wire, which depends on the applied current, has been evaluated utilizing the change in wire-resistance and estimated by heat transfer calculations.

  17. Castro Valley High School's Solar Panels

    Science.gov (United States)

    Lew, A.; Ham, S.; Shin, Y.; Yang, W.; Lam, J.

    2014-12-01

    Solar panels are photovoltaic cells that are designed to convert the sun's kinetic energy to generate usable energy in the form of electricity. Castro Valley High School has tried to offset the cost of electricity by installing solar panels, costing the district approximately 3.29 million dollars, but have been installed incorrectly and are not operating at peak efficency. By using trigonometry we deduced that Castro Valley High School's south facing solar panels were at an incline of 10o and that the east and west facing solar panels are at an incline of 5o. By taking the averages of the optimum angles for the months of September through May, roughly when school is in session, we found that the optimum angle for south facing solar panels should be roughly 46o. This shows that Castro Valley High School has not used it's budget to its full potential due to the fact that the solar panels were haphazardly installed.

    Fabrication of high T{sub c} superconductors and its applications for electric power device were carried out for developing superconductor application technologies. High quality YBCO superconductors was fabricated by melt texture growth, top-seeded melt growth process and multi-seeded melt growth process and the properties was compared. The critical current density of the melt processed YBCO superconductors was about few 10,000 A/cm{sup 2} and the levitation force was 50 N. The processing time needed for the growth of the 123 single grain was greatly reduced by applying multi-seeding without no significant degradation of the levitation force. The multi-seeded melt growth process was confirmed as a time-saving and cost-effective method for the fabrication of bulk superconductors with controlled crystallographic orientation.

    Bondü, Rebecca; Scheithauer, Herbert

    2009-01-01

    In March and September 2009 the school shootings in Winnenden and Ansbach once again demonstrated the need for preventive approaches in order to prevent further offences in Germany. Due to the low frequency of such offences and the low specificity of relevant risk factors known so far, prediction and prevention seems difficult though. None the less, several preventive approaches are currently discussed. The present article highlights these approaches and their specific advantages and disadvantages. As school shootings are multicausally determined, approaches focussing only on single aspects (i.e. prohibiting violent computer games or further strengthening gun laws) do not meet requirements. Other measures such as installing technical safety devices or optimizing actions of police and school attendants are supposed to reduce harm in case of emergency. Instead, scientifically founded and promising preventive approaches focus on secondary prevention and for this purpose employ the threat assessment approach, which is widespread within the USA. In this framework, responsible occupational groups such as teachers, school psychologists and police officers are to be trained in identifying students' warning signs, judging danger of these students for self and others in a systematic process and initiating suitable interventions.

    2009-08-01

    Pulsed current generator was developed for experiments with current carrying pulsed plasma. Main parts of the generator are capacitor bank, low inductive current driving lines, and central load part. Generator consists of four identical sections, connected in parallel to one load. Capacitor bank is assembled from 24 capacitor blocks (100 kV, 80 nF), connected in parallel. It stores 9.6 kJ at 100 kV charging voltage. Each capacitor block incorporates a multigap spark switch, which is able to commute by six parallel channels. Switches operate in dry air at atmospheric pressure. The generator was tested with an inductive load and a liner load. At 17.5 nH inductive load and 100 kV of charging voltage it provides 650 kA of current amplitude with 390 ns rise time with 0.6 ohms damping resistors in discharge circuit of each capacitor block. The net generator inductance without a load was optimized to be as low as 15 nH, which results in extremely low impedance of the generator (approximately 0.08 ohms). It ensures effective energy coupling with a low impedance load such as Z pinch. The generator operates reliably without any adjustments in 70-100 kV range of charging voltage. Jitter in delay between output pulse and triggering pulse is less than 5 ns at 70-100 kV charging voltage. Operation and handling are very simple, because no oil or purified gases are required for the generator. The generator has dimensions 5.24x1.2x0.18 m(3) and total weight about 1400 kg, thus manifesting itself as simple, robust, and cost effective apparatus.

  6. ISAC target operation with high proton currents

    2003-01-01

    The TRIUMF-ISAC facility target stations were designed for ISOL target irradiations with up to 100 mu A proton beam currents. Since beginning operation in 1998, ISAC irradiation currents have progressively increased from initial values of approx 1 mu A to present levels of up to 40 mu A on refractory metal foil targets. In addition, refractory carbide targets have operated at currents of up to 15 mu A for extended periods. The 1-40 mu A operational regime is achieved by tailoring each target to the thermal requirements dictated by material properties such as beam power deposition, thermal conductivity and maximum operating temperature of the target material. The number of heat shields on each target can be varied in order to match the effective emissivity of the target surface for the required radiative power dissipation. Targets of different thickness, surface area and volume have been investigated to study the effect of diffusion and effusion delays on the yield of radioisotopes. For yields of short-lived p...

  11. Science school and culture school: improving the efficiency of high school science teaching in a system of mass science education.

    Science.gov (United States)

    Charlton, Bruce G

    2006-01-01

    Educational expansion in western countries has been achieved mainly by adding years to full-time education; however, this process has probably reduced efficiency. Sooner or later, efficiency must improve, with a greater educational attainment per year. Future societies will probably wish more people to study science throughout high school (aged c. 11-19 years) and the first college degree. 'Science' may be defined as any abstract, systematic and research-based discipline: including mathematics, statistics and the natural sciences, economics, music theory, linguistics, and the conceptual or quantitative social sciences. Since formal teaching is usually necessary to learn science, science education should be regarded as the core function of high schools. One standard way to improve efficiency is the 'division of labour', with increased specialization of function. Modern schools are already specialized: teachers are specialized according to age-group taught, subject matter expertise, and administrative responsibilities. School students are stratified by age and academic aptitude. I propose a further institutional division of school function between science education, and cultural education (including education in arts, sports, ethics, social interaction and good citizenship). Existing schools might split into 'science school' and 'culture school', reflected in distinct buildings and zones, separate administrative structures, and the recruitment of differently-specialized teaching personnel. Science school would be distinguished by its focus on education in disciplines which promote abstract systematic cognition. All students would spend some part of each day (how much would depend on their aptitude and motivation) in the 'science school'; experiencing a traditional-style, didactic, disciplined and rigorous academic education. The remainder of the students' time at school would be spent in the cultural division, which would focus on broader aspects, and aim to generate

    The University of Washington in the High School (UWHS) program enables high schools to offer the 5 quarter credits Astronomy 101 (Astr 101) course for college credits. The credits are transferable to most colleges and universities. The course provides an alternative to advance placement courses and programs such as Washington's Running Start whereby high school students take courses at community colleges. Astr 101 focuses on stars, galaxies and the universe, as well as background topics such as gravitation, electromagnetic radiation and telescopes. The course satisfies the UW "natural world” and "quantitative/symbolic reasoning” distribution requirements. Students must pay a fee to enroll, but the credits cost less than half what they would cost for the course if taken on one of the UW campuses. The course can be offered as either one semester or full-year at the high school. Teachers who offer Astr 101 must be approved in advance by the UW Astronomy Department, and their syllabi and course materials approved also. Teachers receive orientation, professional development opportunities, classroom visits and support (special web site, answering questions, making arrangements for campus visits, planetarium visits) from astronomy department course coordinator. The UWHS Astr 101 program has produced positive outcomes for the astronomy department, the participating teachers and the students who complete the course. In this poster we will discuss our 5 years of experience with offering Astr 101, including benefits to the students, teachers, high schools, university and department, student outcomes, course assessments and resources for offering the course.

    2013-01-01

    Graduate students at the University of Virginia (UVa) are volunteering as research advisors on astronomy projects for Virginia's science and technology high schools. In previous years, we have worked with more than a dozen students through a research class at Central Virginia Governor's School in Lynchburg to develop an astronomy research curriculum that teaches background concepts and terminology, guides students in data analysis, and prepares them to present material in poster and oral forums. In our fourth year of operation, we are continuing to work with Central Virginia Governor's School and adapting the research curriculum to an independent course at Roanoke Valley Governor's School in Roanoke. Because both schools are far from UVa in Charlottesville, the program operates remotely; graduate advisors and high school students interact through "virtual" means, establishing a successful framework for meaningful remote mentoring. In the current year, six students will complete projects on astrophysical topics including megamasers, astrochemistry, and pulsars using data taken by the Green Bank Telescope (GBT). Students at Roanoke Valley were directly trained on the GBT as part of a separate outreach program called the Pulsar Search Collaboratory, and all six students will receive hands-on experience in handling GBT data. The current projects are components of larger research efforts by graduate student and professional level researchers, so that the projects contribute to high-level projects only possible with the GBT. This stands as a rare outreach program that uses the principle of “deliberative practice” to train high school students in the development of skills that are crucial to success in science. Furthermore, it provides graduate students with an opportunity to plan and advise research projects, developing a skill set that is required in more advanced academic positions. Our poster discusses the implementation of our online curriculum in two distinct

    Sinclair, C K

    2005-01-01

    Cornell University is constructing a 100 mA average current, high brightness electron injector for a planned Energy Recovery Linac (ERL) hard X-ray synchrotron radiation source. This injector will employ a very high voltage DC gun with a negative electron affinity photoemission cathode. Relatively long duration electron pulses from the photocathode will be drift bunched, and accelerated to 5-15 MeV with five two-cell, 1300 MHz superconducting cavities. The total beam power will be limited to 575 kW by the DC and RF power sources. A genetic algorithm based computational optimization of this injector has resulted in simulated rms normalized emittances of 0.1 mm-mrad at 80 pC/bunch, and 0.7 mm-mrad at 1 nC/bunch. The many technical issues and their design solutions will be discussed. Construction of the gun and the SRF cavities is well underway. The schedule for completion, and the planned measurements, will be presented.

    2005-04-01

    In an effort to help high school physics teachers bring technology into their classrooms, we at JSU have been offering professional development to secondary education teachers. This effort is part of Project IMPACTSEED (IMproving Physics And Chemistry Teaching in SEcondary Education), a No-Child Left Behind (NCLB) grant funded by the Alabama Commission on Higher Education, serving high school physics teachers in Northeast Alabama. This project is motivated by a major pressing local need: A large number of high school physics teachers teach out of field. To achieve IMPACTSEED's goals, we have forged a functional collaboration with school districts from about ten counties. This collaboration is aimed at achieving a double aim: (a) to make physics and chemistry understandable and fun to learn within a hands-on, inquiry-based setting; (b) to overcome the fear- factor for physics and chemistry among students. Through a two-week long summer institute, a series of weekend technology workshops, and onsite support, we have been providing year-round support to the physics/chemistry teachers in this area. This outreach initiative has helped provide our students with a physics/chemistry education that enjoys a great deal of continuity and consistency from high school to college.

    Full Text Available This paper analyzes the consequences of peer victimization for the satisfaction with schooling (“happiness” of college-bound high school graduates in Brazil.  Several types of victimization are explored including discrimination due to race/ethnicity, socioeconomic status, gender, sexual orientation, religious affiliation, and disability. We compare the satisfaction with their schooling of students planning to head to college straight from high school and older students applying for college later in life (“nontraditional students”. We conclude that students who perceived that they had been discriminated against were more dissatisfied with their school experience than those who did not, ceteris paribus, and we relate level of dissatisfaction to type of discrimination. The older student evidence reveals that this dissatisfaction wanes with time and age, however. Our conclusions are based upon ordered logistic analyses of data for 2.4 million current high school seniors and 78.7 thousand older students drawn from the Exame Nacional do Ensino Médio questionnaire (ENEM.

  16. Developing High School Geoscientists through Summer Internships

    Saltzman, J.

    2012-12-01

    High school students in the San Francisco Bay Area have the opportunity to contribute to Earth sciences research during the summer at Stanford University. The School of Earth Sciences hosts about 25 high school students each summer to support ongoing research, through more than just washing glassware. To increase diversity in the geosciences, we select students from diverse backgrounds through an application process which lessens the burden on busy faculty. The students work for 15-20 hours per week under the supervision of graduate students or postdoctoral fellows. The supervisors come to value the interns for a few reasons: not only are they getting some extra help with their research, but they are getting teaching experience in an informal but powerful way and supervising the interns' work over the summer. Another key part of the internship is bringing all of the interns together regularly. Whether it is for career talks, lab tours or field trip, high school students find kindred spirits in the group. Another important reason for weekly gatherings is to introduce the students to the wide field of Earth sciences and the different approaches and paths that scientists take. The summer ends with a culminating event where interns make short informal presentations about their research which give them an opportunity to articulate the big questions they have been helping to answer. Some interns are also invited to present a poster in a session for high school students at the Fall AGU meeting. These experiences of working in the laboratory and communicating about the research are part of the world of Earth sciences that are absent for most youth. The high school internships foster good will between Stanford and the local communities, help develop a more Earth and environmentally knowledgeable public and may have a long-term affect on diversifying the geosciences by exposing more young people to these fields.

Currently the teachers in high school education find themselves in an unprecedented situation due to the recent obligatory nature of this education level, the equally recent education reforms and the application of the competency education approach. Formed in many cases for teachers with no pedagogical formation or experience, the staff of high school education faces the institutional requirements with very few elements to be able to satisficed. In this context it began to be introduced the alternative of the Education for peace, but it is necessary to reflect upon the real possibilities of the schools, their authorities, their teachers and their students to accomplish it.

  19. School Start Times for Middle School and High School Students - United States, 2011-12 School Year.

    Adolescents who do not get enough sleep are more likely to be overweight; not engage in daily physical activity; suffer from depressive symptoms; engage in unhealthy risk behaviors such as drinking, smoking tobacco, and using illicit drugs; and perform poorly in school. However, insufficient sleep is common among high school students, with less than one third of U.S. high school students sleeping at least 8 hours on school nights. In a policy statement published in 2014, the American Academy of Pediatrics (AAP) urged middle and high schools to modify start times as a means to enable students to get adequate sleep and improve their health, safety, academic performance, and quality of life. AAP recommended that "middle and high schools should aim for a starting time of no earlier than 8:30 a.m.". To assess state-specific distributions of public middle and high school start times and establish a pre-recommendation baseline, CDC and the U.S. Department of Education analyzed data from the 2011-12 Schools and Staffing Survey (SASS). Among an estimated 39,700 public middle, high, and combined schools* in the United States, the average start time was 8:03 a.m. Overall, only 17.7% of these public schools started school at 8:30 a.m. or later. The percentage of schools with 8:30 a.m. or later start times varied greatly by state, ranging from 0% in Hawaii, Mississippi, and Wyoming to more than three quarters of schools in Alaska (76.8%) and North Dakota (78.5%). A school system start time policy of 8:30 a.m. or later provides teenage students the opportunity to achieve the 8.5-9.5 hours of sleep recommended by AAP and the 8-10 hours recommended by the National Sleep Foundation.

    The result and outcome of the cloud chamber project, which aims to develop a cloud chamber useful for science education is reported in detail. A project includes both three high school students and a teacher as a part of Super Science High School (SSH) program in our school. We develop a dry ice free cloud chamber using salt and ice (or snow). Technical detail of the chamber is presented. We also argue how the project affects student's cognition, motivation, academic skills and behavior. The research project had been done in very similar way to those of professional researchers, i.e., planning research, applying fund, writing a paper and giving a talk in conferences. From interviews with students, we learn that such style of scientific activity is very effective in promoting student's motivation for learning science.

    Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.

    Tobacco use is the leading cause of preventable disease and death in the United States; if current smoking rates continue, 5.6 million Americans aged students. In 2015, e-cigarettes were the most commonly used tobacco product among middle (5.3%) and high (16.0%) school students. During 2011-2015, significant increases in current use of e-cigarettes and hookahs occurred among middle and high school students, whereas current use of conventional tobacco products, such as cigarettes and cigars decreased, resulting in no change in overall tobacco product use. During 2014-2015, current use of e-cigarettes increased among middle school students, whereas current use of hookahs decreased among high school students; in contrast, no change was observed in use of hookahs among middle school students, use of e-cigarettes among high school students, or use of cigarettes, cigars, smokeless tobacco, pipe tobacco, or bidis among middle and high school students. In 2015, an estimated 4.7 million middle and high school students were current tobacco product users, and, therefore, continue to be exposed to harmful tobacco product constituents, including nicotine. Nicotine exposure during adolescence, a critical period for brain development, can cause addiction, might harm brain development, and could lead to sustained tobacco product use among youths. Comprehensive and sustained strategies are warranted to prevent and reduce the use of all tobacco products among U.S. youths.

The abstract nature of pure physics is often made more accessible when motivated by examples from everyday life, and providing copious mathematical as well as conceptual examples has become standard practice in high school physics textbooks. Astronomy is a naturally captivating subject and astronomical examples are often successful in capturing the curiosity of high school students as well as the general population. This project seeks to diversify the range of pedagogical materials available to the high school physics instructor by compiling and publishing specific examples where an astronomical concept can be used to motivate the physics curriculum. This collection of examples will consist of both short problems suitable for daily homework assignments as well as longer project style activities. Collaborations are encouraged and inquiries should be directed to sdieterich at carnegiescience dot edu.This work is funded by the NSF Astronomy and Astrophysics Postdoctoral Fellowship Program through NSF grant AST-1400680.

    Full Text Available Introduction: the problem of formulation of social mandate at the level of primary education is caused by integration, globalisation processes, and introduction of reforms in education. The contemporary society puts forward new requirements to education system which has to meet demands of various social actors, involved in the educational process. Social mandate is a tool of interaction between society and education by which the diverse consumers of educational services can express their educational needs. A student as the main subject of education takes the special place among the consumers of educational services. Clearly defined social mandates ensures quality of education, therefore this article focuses on the attempt of formulating social mandate for the high school on behalf of a learner. Materials and Methods: a theoretical analysis of pedagogical and sociological literature was made in the process of writing the article. Results: the domestic and international experience in elaboration of the social mandate for the high school was explored and summarised. The main targets of social mandate at the level of basic education was analysed. Discussion and Conclusions: the paper describes the specifics of formulation of the social mandate (specific interests, needs, requirements and requests to high school, that high school should work towards to be able to maintain its competitiveness in the modern market society.

    2014-06-01

    High school is an important time in the educational career of students. It is also a time when adolescents face many behavioral, academic, and social-emotional challenges. Current statistics about the behavioral, academic, and social-emotional challenges faced by adolescents, and the impact on society through incarceration and dropout, have prompted high schools to direct their attention toward keeping students engaged and reducing high-risk behavioral challenges. The purpose of the study was to examine the effects of School-Wide Positive Behavioral Interventions and Supports (SW-PBIS) on the levels of individual student problem behaviors during a 3-year effectiveness trial without random assignment to condition. Participants were 36,653 students in 12 high schools. Eight schools implemented SW-PBIS, and four schools served as comparison schools. Results of a multilevel latent growth model showed statistically significant decreases in student office discipline referrals in SW-PBIS schools, with increases in comparison schools, when controlling for enrollment and percent of students receiving free or reduced price meals. In addition, as fidelity of implementation increased, office discipline referrals significantly decreased. Results are discussed in terms of effectiveness of a SW-PBIS approach in high schools and considerations to enhance fidelity of implementation.

Material and methods: The study was carried out in March 2011 in high schools in Szczecin. Own elaborated questionnaire was used. 288 students from high school, technical college and vocational school were tested. Results: The majority of responders (95,1% claimed that cigarette smoke is harmful both for passive and active smokers. They most often pinpoint the direct cause connected with smoking to pulmonary diseases (264 persons and cancers (240 persons. Almost 90% of students found negative impact of tobacco products on development of fetus of pregnant women. Overwhelming majority of respondents (83,2% feels anxious if it comes to stay in a room filled with smoke. Conclusions: The awareness of high school students on negative influence of smoking on human body is quite satisfactory, but there is still a need for more education in the range of diseases and symptoms connected with smoking.

  10. Facilitating problem solving in high school chemistry

    Science.gov (United States)

    Gabel, Dorothy L.; Sherwood, Robert D.

    The major purpose for conducting this study was to determine whether certain instructional strategies were superior to others in teaching high school chemistry students problem solving. The effectiveness of four instructional strategies for teaching problem solving to students of various proportional reasoning ability, verbal and visual preference, and mathematics anxiety were compared in this aptitude by treatment interaction study. The strategies used were the factor-label method, analogies, diagrams, and proportionality. Six hundred and nine high school students in eight schools were randomly assigned to one of four teaching strategies within each classroom. Students used programmed booklets to study the mole concept, the gas laws, stoichiometry, and molarity. Problem-solving ability was measured by a series of immediate posttests, delayed posttests and the ACS-NSTA Examination in High School Chemistry. Results showed that mathematics anxiety is negatively correlated with science achievement and that problem solving is dependent on students' proportional reasoning ability. The factor-label method was found to be the most desirable method and proportionality the least desirable method for teaching the mole concept. However, the proportionality method was best for teaching the gas laws. Several second-order interactions were found to be significant when mathematics anxiety was one of the aptitudes involved.

The body of the book is supported with statistical data. There are three periods outlined within the development – the first one covers the time till the Liberation, from the Liberation until 1909 while the third one is from 1909 to 1944. The second period is characterized by a strive towards the leveling of the male and female secondary schools and their consolidation as a ground for higher education. During the third period the high school takes after the European one, it develops steadily and the short and ineffective changes do not bear any influence on the gradual expansion of the web of high schools (full – male, female, mixed or semigymnasium, with a real, half-classical or classical curriculum.

    Fortus, David; Shwartz, Yael; Rosenfeld, Sherman

    2016-12-01

    Modeling is a core scientific practice. This study probed the meta-modeling knowledge (MMK) of high school students who study science but had not had any explicit prior exposure to modeling as part of their formal schooling. Our goals were to (A) evaluate the degree to which MMK is dependent on content knowledge and (B) assess whether the upper levels of the modeling learning progression defined by Schwarz et al. (2009) are attainable by Israeli K-12 students. Nine Israeli high school students studying physics, chemistry, biology, or general science were interviewed individually, once using a context related to the science subject that they were learning and once using an unfamiliar context. All the interviewees displayed MMK superior to that of elementary and middle school students, despite the lack of formal instruction on the practice. Their MMK was independent of content area, but their ability to engage in the practice of modeling was content dependent. This study indicates that, given proper support, the upper levels of the learning progression described by Schwarz et al. (2009) may be attainable by K-12 science students. The value of explicitly focusing on MMK as a learning goal in science education is considered.

    Bowen, Natasha K; Powers, Joelle D

    2005-11-01

    OBJECTIVE: The purpose of the current study was to examine the practice validity of a new ecological assessment instrument for 3(rd) through 5(th) graders in terms of whether it provided school staff with new knowledge about students. METHOD: Pre-assessment knowledge of school staff was compared to data obtained from 21 children and their parents on 29 measures. Data were collected using the Elementary School Success Profile (ESSP). School staff pre-assessment knowledge was compared to obtained data across seven domains of children's lives (neighborhood, school, family, peers, parent educational involvement, well-being, and home behavior), data sources (child and parent), and grade level of students. RESULTS: Pre-assessment knowledge was not highly correlated with obtained data; pre-assessment expectations matched obtained data only about 41% of the time; and knowledge varied by domain, source, and grade level. CONCLUSIONS: Ecological assessments can address gaps in school staff's knowledge of targetable factors that influence the success of students.

    Sayers, J.

    2004-12-01

    Through a series of summer workshops, seismologists at Indiana University have trained secondary physics and earth science teachers in fundamentals of seismology and basic concepts in seismic research. Teachers and students then gain hands on experience in science research through operation of a research quality seismic station sited at the local schools. Physics and earth science students have operated the Northview High School Seismic Station since 1998. Data from the Northview seismometer are stored locally and also transmitted over the Internet to a database at Indiana University. Students have access to local data as well as seismic databases accessible through the Internet to use for research projects. In this presentation, I will describe how these projects have been incorporated into the physics and earth science programs at Northview High School. I will discuss how our teachers and students have benefited from the opportunity to take part in hands-on collaborative scientific research under the guidance of university faculty. In particular, I will describe our participation in a regional seismic network through seismic data acquisition, data analysis using seismological software, and students' experiences in a university-based student research symposium. I reflect on the some of the successes, such as increased student and community interest, resulting from our work with the seismic station. I comment on some of the barriers, such as time constraints and unintended interference from school personnel, to high-school teachers' and students' involvement in scientific research programs. I conclude with a discussion of a successful student seismology project, an examination of blasts from local surface coal mines, that was a finalist in the 2003 INTEL International Science and Engineering Fair

    2010-05-01

    Full Text Available Motivation studies have focused on three aspects that are important for their educational implications: relevant variables for assessing motivation to attend school; motivational differences between students with different academic performance, and changes in motivation as they advance in school. Considering these aspects, the present study was developed with these objectives: to develop, and to set up the validity and reliability of a psychometric instrument for investigating how people perceive different motivational variables regarding various school activities typical of the Mexican junior high school; and to find out whether there is a relationship between motivational variables and academic achievement, grade level and gender. The results indicate that academic performance is related to the way motivation is perceived, that students change their perception of motivation during their school life, and that boys and girls differ concerning this only in some respects.

    Participating in sports while experiencing symptoms of a concussion can be dangerous. An athlete's lack of knowledge may be one factor influencing his or her decision to report symptoms. In an effort to enhance concussion education among high school athletes, legislation in Florida has attempted to address the issue through parental consent forms. To survey high school varsity football players to determine their level of knowledge about concussions after the initiation of new concussion-education legislation. Cross-sectional study. Descriptive survey administered in person during a team meeting. A total of 334 varsity football players from 11 high schools in Florida. Participants completed a survey and identified the symptoms and consequences of a concussion among distractors. They also indicated whether they had received education about concussions from a parent, formal education, neither, or both. The most correctly identified symptoms were headache (97%), dizziness (93%), and confusion (90%), and the most correctly identified consequence was persistent headache (93%). Participants reported receiving education from their parents (54%) or from a formal source (60%). Twenty-five percent reported never receiving any education regarding concussions. No correlations were found between the method of education and the knowledge of symptoms or consequences of concussion. The high school football players we surveyed did not have appropriate knowledge of the symptoms and consequences of concussions. Nausea or vomiting, neck pain, grogginess, difficulty concentrating, and personality or behavioral changes were often missed by participants, and only a small proportion correctly identified brain hemorrhage, coma, and death as possible consequences of inappropriate care after a concussion. Even with parents or guardians signing a consent form indicating they discussed concussion awareness with their child, 46% of athletes suggested they had not.

  4. Forensic Science Curriculum for High School Students

    Science.gov (United States)

    Burgess, Christiana J.

    Over the last several decades, forensic science---the application of science to civil and criminal legal matters---has become of increasing popularity with the public. The range of disciplines within the field is immense, offering individuals the potential for a unique career, regardless of their specific interests or expertise. In response to this growth, many organizations, both public and private, have recognized the need to create forensic science programs that strive to maintain and enhance the quality of forensic science education. Unfortunately, most of the emphasis placed on developing these materials relates to post-secondary education, and creates a significant lack of forensic science educational materials available in the U.S., especially in Oklahoma. The purpose of this project was to create a high school curriculum that provides the foundation for building a broad, yet comprehensive, overview of the field of forensic science and its associated disciplines. The overall goal was to create and provide course materials to high school teachers in order to increase their knowledge of forensic science such that they are able to teach its disciplines effectively and with accuracy. The Forensic Science Curriculum for High School Students includes sample lesson plans, PowerPoint presentations, and lab activities with step-by-step instructions.

    2010-03-01

    This article describes the development of a direct-current (dc) superconducting transformer system for the high current test of superconducting cables. The transformer consists of a core-free 10,464 turn primary solenoid which is enclosed by a 6.5 turn secondary. The transformer is designed to deliver a 50 kA dc secondary current at a dc primary current of about 50 A. The secondary current is measured inductively using two toroidal-wound Rogowski coils. The Rogowski coil signal is digitally integrated, resulting in a voltage signal that is proportional to the secondary current. This voltage signal is used to control the secondary current using a feedback loop which automatically compensates for resistive losses in the splices to the superconducting cable samples that are connected to the secondary. The system has been commissioned up to 28 kA secondary current. The reproducibility in the secondary current measurement is better than 0.05% for the relevant current range up to 25 kA. The drift in the secondary current, which results from drift in the digital integrator, is estimated to be below 0.5 A/min. The system's performance is further demonstrated through a voltage-current measurement on a superconducting cable sample at 11 T background magnetic field. The superconducting transformer system enables fast, high resolution, economic, and safe tests of the critical current of superconducting cable samples.

    The current study analyzed the effectiveness of integrating parents in the education of their children through interactive homework (IH). More specifically, the research questions of the study examined the effectiveness, feasibility, and usefulness of parental involvement in increasing academic performance within high school science classes. Using a mixed method design with a single IH treatment group, a convenience sample of 84 anatomy and biology students was assessed over a 6-week period. Although Spearman correlations failed to reveal any associations linking hours of parental IH involvement with student outcomes, related-samples t tests of pre/post student performance indicated significant increases in homework, test scores and overall grades, with greatest improvement observed in test scores. Exit questionnaires, focus groups, and interviews were coded for emergent themes that in turn were analyzed for common patterns. These qualitative data revealed positive feedback related to specific program components and a general interest for program continuation. The results indicated that it is possible to successfully incorporate parents at the high school level, even in technical subject areas. The research may be of particular interest to families and educators due to the positive scholastic effects of incorporating parents in high school academics. Social change is generated by incorporating parents into the educational process which strengthens the school-home bond and contributes to student achievement and motivation.

  8. Stable and unstable thermo -current states of high temperature superconductors

    2008-02-01

    Formation peculiarities of the stable and unstable states of high-T{sub c} superconductors are discussed. To understand the basic physical trends, which are characteristic for the current penetration mechanism in high temperature superconductors, the operating states of Bi2212 slab without stabilizing matrix placed in DC external magnetic fields at low coolant temperature are theoretically investigated. It is proved that the temperature of a high-T{sub c} superconductor is not equals to the coolant temperature before instability onset. Therefore, the voltage-current characteristic of a high-T{sub c} superconductor has only a positive slope during continuous current charging. As a result, it does not allow one to find the boundary between stable and unstable thermo - current states. This peculiarity has to be considered during experiments at which the critical current of high-T{sub c} superconductors is defined.

    2017-04-01

    In Austria there are currently some major reforms concerning high school education underway. At our school, the Bundesgymnasium and Bundesrealgymnasium Draschestrasse, a school belonging to the Vienna Bilingual Schooling branch, we have developed a course system in which pupils can select courses and determine individually which areas of study they want to focus on. Specially devised courses have been developed which fit within the framework of natural and applied sciences but go beyond the basic curriculum in physics. Geodynamics is the title of one of these courses, with an emphasis on weather, climate and geodynamic processes of the earth's crust. The course „The restless earth" deals specifically with plate tectonics, vulcanism, formation of mountains and processes such as ocean currents and the physics involved. Apart from theoretical basics we use manifold media and approaches concerning visualization: graphics, map data taken from Google Maps, satellite pictures, and others. The knowledge acquired in this course is broadened and consolidated by means of excursions to the Vienna Natural History Museum where additional instructional materials and visual aids are on display. Based on this experience pupils are requested to hold presentations (individually or in groups) at the end of the course.

  11. Merits of Undergraduate and High School Research

    Kenney, John

    2016-06-01

    When it comes to sports, everyone gets it; you have to play to really understand, experience, and learn what the game is all about. It would be ludicrous to teach basketball by practicing basketball fundamentals in the gym (layups, free throws, jump shots, dribbling, defense), reading about and attending professional basketball games, but never playing in a game. As important as classes and teaching laboratories may be in science education, there is simply no substitute for active engagement in scientific research to show students what science is all about and, perhaps even more importantly, to inspire and motivate them to become scientists or at least appreciate science. It is a widely held misconception that a student cannot really do meaningful, publishable scientific research until he/she is in graduate school. In actual fact, college undergraduates and even high school students can make original and significant scientific research contributions. Astronomical research, in particular, is very well suited to engage the beginning high school or college undergraduate researcher. The night sky’s inherent accessibility and also its inherent grandeur are natural draws for the curious student’s mind. And much can be learned and discovered using small telescopes. In sports, joining a team is a key aspect of the sports experience. Similarly in science, joining a research team and thereby entering a “community of scientific practice” is fundamental and transformational. As important as working with equipment and acquiring data happen to be in scientific research, this is only the beginning of the research process. Student researchers of all ages—particularly high school students and college undergraduates—have much to gain by giving presentations on their research, writing up their results for publication, and going through the peer review process. But this only works if the student researchers are imbedded within the community of practice.

    2013-11-01

    Full Text Available In this study, a novel, differential pair based, high performance and high bandwidth current subtractor is proposed. Very low equivalent impedances are obtained at input ports n and p by using source follower transistors. Furthermore, the proposed circuit is self-biasing which makes it resistant to process, supply voltage and temperature variations. The proposed current subtractor can be used as an input stage for current-mode active circuits like current differencing buffered amplifier (CDBA, operational transresistance amplifier (OTRA and current differencing transconductance amplifier (CDTA which employ current subtractors. A numeric figure-of-merit is defined and it is used to demonstrate the superior performance of the proposed circuit.

This decline may be due to psychological and social reasons. It is shown that risk factors of involving in chemical dependency are meaningfully disclosed in longitudinal studies, whereas the dynamics of personal change during the formation of anti-addictive prevention skills are more fully disclosed in the comparative age sections. The typical phenomena, accompanying the downward trend in prevention, are the growth of problem behavior and the crisis of mass dropout. Such phenomena are so great that they are recognized as a crisis at a state level.

    Full Text Available In this study, it is aimed to determine the high school students’ views on blended learning. The study was carried out in biology course for the lesson unit of “Classification of Living Things and Biodiversity” with 47 9th grade students attending Nevzat Ayaz Anatolian High School in the second term of the academic year of 2009-2010. The lessons were taught in a way appropriate to the blended learning model both via the Internet and on face-to-face basis. As the online dimension of the blended learning model, Moodle, a Learning Management System (LMS, was used. The application lasted 10 weeks. The scale of learners’ views on blended learning was applied and interviews were held to determine the views. As a result of the analysis of the scale, it was seen that their views were “highly” positive. The interviews held with the students revealed that the blended learning model provided students with various opportunities such as getting prepared for the lessons, reviewing the lessons as many times as wanted, reaching the subject-related materials without being dependent on time and place, testing oneself and communicating with the teacher and other students out of the school. The interviews also revealed that there were various problems though such as lack of Internet connection at home and problems experienced while playing the videos.

    Although cigarette use by adolescents is declining, emerging tobacco products are becoming increasingly popular and youth may use more than one type of tobacco product. The purposes of this study were: (1) to assess patterns of poly-tobacco use among a representative sample of high school students and (2) to determine how beliefs correlate with poly-tobacco use. Data came from the 2013 North Carolina Youth Tobacco Survey (n = 4092). SAS logistic regression survey procedures were used to account for the complex survey design and sampling weights. Among all high school students in NC in 2013, 29.7% reported current any tobacco use, with 19.1% reporting current poly-tobacco use, and 10.6% reporting current use of only one product. Among poly-tobacco users, 59.3% reported that one of the products they currently used was cigarettes. Positive tobacco product beliefs were found to be significantly associated with poly-tobacco use. Communication campaigns, policy efforts, and future research are needed for prevention, regulation, and control of poly-tobacco use among adolescents, which represents a significant public health problem.

    Cathode erosion rate was experimentally investigated for two types of arcs: one with tungsten cathode in nitrogen atmosphere and one with hafnium cathode in oxygen atmosphere. Conditions were typical for plasma arc cutting systems: gas pressure from 2 to 5 atm, arc current from 200 to 400 A, gas flow rate from 50 to 130 litre min sup - sup 1. It was found that the actual cathode evaporation rate G is much lower than G sub 0 , the evaporation rate that follows from the Hertz-Knudsen formula: G = nu G sub 0. The difference is because some of the evaporated particles return back to the cathode. For conditions of our experiments, the factor nu could be as low as 0.01. It was shown experimentally that nu depends strongly on the gas flow pattern close to the cathode. In particular, swirling the gas increases nu many times. To explain the influence of gas swirling, model calculations of gas flows were performed. These calculations revealed difference between swirling and non-swirling flows: swirling the gas enhances...

  13. Tobacco use among middle and high school students --- United States, 2000-2009.

    Science.gov (United States)

    2010-08-27

    Tobacco use continues to be the single leading preventable cause of death and disease in the United States. More than 80% of established adult smokers begin smoking before age 18 years. To monitor trends in tobacco use among middle and high school students, CDC analyzed 2000-2009 data from the National Youth Tobacco Survey (NYTS), a school-based survey that collects information on tobacco use and related behaviors and attitudes from middle school (grades 6-8) and high school (grades 9-12) students. This analysis indicated that in 2009, 8.2% of middle school students and 23.9% of high school students reported current use of any tobacco product; 5.2% of middle school students and 17.2% of high school students reported current use of cigarettes. Overall prevalence did not decrease from 2006 to 2009 for use of any tobacco product among either group. During 2000-2009, the prevalence of current tobacco use among middle school students declined (15.1% to 8.2%), as did current cigarette use (11.0% to 5.2%) and cigarette smoking experimentation (29.8% to 15.0%). Similar trends were observed for high school students (current tobacco use: 34.5% to 23.9%; current cigarette use: 28.0% to 17.2%; cigarette smoking experimentation: 39.4% to 30.1%). Overall, no change in susceptibility to initiate cigarette smoking was observed for either group. To further decrease tobacco use and susceptibility to use among youths, restrictions on advertising, promotion, and availability of tobacco products to youths should be combined with full implementation of evidence-based, communitywide, comprehensive tobacco control policies.

    Samuelson, Anne; Lytle, Leslie; Pasch, Keryn; Farbakhsh, Kian; Moe, Stacey; Sirard, John Ronald

    2010-11-01

    This article describes policies, practices, and facilities that form the physical activity climate in Minneapolis/St. Paul, Minnesota metro area middle and high schools and examines how the physical activity climate varies by school characteristics, including public/private, school location and grade level. Surveys examining school physical activity practices, policies and environment were administered to principals and physical education department heads from 115 middle and high schools participating in the Transdisciplinary Research on Energetics and Cancer-Identifying Determinants of Eating and Activity (TREC-IDEA) study. While some supportive practices were highly prevalent in the schools studied (such as prohibiting substitution of other classes for physical education); other practices were less common (such as providing opportunity for intramural (noncompetitive) sports). Public schools vs. private schools and schools with a larger school enrollment were more likely to have a school climate supportive of physical activity. Although schools reported elements of positive physical activity climates, discrepancies exist by school characteristics. Of note, public schools were more than twice as likely as private schools to have supportive physical activity environments. Establishing more consistent physical activity expectations and funding at the state and national level is necessary to increase regular school physical activity.

    1997-11-01

    Heating and noninductive current drive in NSTX will initially use 6 MW of rf power in the high harmonic fast wave (HHFW) regime. We present numerical modelling of HHFW heating and current drive in NSTX using the PICES, CURRAY, FISIC, and METS95 codes. High electron β during the discharge flattop in NSTX is predicted to result in off-axis power deposition and current drive. However, reductions in the trapped electron fraction (due also to high β effects) are predicted to result in adequate current drive efficiency, with ~ 400 - 500 kA of noninductive current driven. Sufficient per-pass absorption (>10%) to ensure effective electron heating is also expected for the startup plasma. Present plans call for a single twelve strap antenna driven by six FMIT transmitters operating at 30 MHz. The design for the antenna and matching system will also be discussed.

    2013-01-01

    The current study examined the association among home-school dissonance, amotivation, and classroom disruptive behavior among 309 high school juniors and seniors at two urban high schools in the Southern region of the country. Students completed two subscales of the Patterns of Learning Activities Scales (PALS) and one subscale of the Academic Motivation Scale (AMS). ANCOVA analyses revealed significant differences in classroom disruptive behaviors for the gender independent variable. Controlling for gender in the multiple hierarchical regression analyses, it was revealed that home-school dissonance significantly predicted both amotivation and classroom disruptive behavior. In addition, a Sobel mediation analysis showed that amotivation was a significant mediator of the association between home-school dissonance and classroom disruptive behavior. Findings and limitations are discussed.

    2015-05-01

    Full Text Available Starting with a short retrospective and an overview of the incorporation of foreign language learning into the Austrian curriculum for primary schools the paper in hand describes the current situation of foreign language teaching in primary schools as well as various current models of foreign language education in primary schools in Vienna (school year 1 to 4. In terms of objectives these models exceed the requirements of the curriculum of the formal education system or regard themselves as quantitative and qualitative enrichment. They follow different didactic approaches and/or site-specific characteristics and needs. The formulation of basic skills is to be understood as an attempt to find a common basis of output indicators and to facilitate the transition to secondary education. Although English is the most commonly chosen resp. offered language the paper also refers to school experiments that focus on Romance or Slavic languages or on languages of Austra’s neighbouring countries.

    2014-01-01

    The University of Chicago Multiwavelength Astronomy modules are web-based lessons covering the history, science, tools, and impact of astronomy across the wavebands, from gamma ray to infrared. Each waveband includes four lessons addressing one aspect of its development. The lessons are narrated by a historical docent or practicing scientist who contributed to a scientific discovery or instrument design significant to astronomical progress. The process of building each lesson began with an interview conducted with the scientist, or the consultation of a memoir or oral history transcript for historical docents. The source was then excerpted to develop a lesson and supplemented by archival material from the University of Chicago Library and other archives; NASA media; and participant contributed photographs, light curves, and spectra. Practicing educators also participated in the lesson development and evaluation. In July 2013, the University of Chicago sponsored 9 teachers and 15 students to participate in a STEM education program designed to engage participants as co-learners as they used the Multiwavelength Astronomy lessons in conjunction with talks given by the participating scientists. Teachers also practiced implementation of the resources with students and designed authentic research activities that make use of NASA mission data, which were undertaken as mini-research projects by student teams during the course of the program. This poster will introduce the Multiwavelength Astronomy web modules; highlight educator experiences in their use with high school audiences; and analyze the module development process, framing the benefits to and contributions of each of the stakeholders including practicing astronomers in research and space centers, high school science educators, high school students, University libraries and archives, and the NASA Science Mission Directorate. The development of these resources, and the summer professional development workshops were

    To screen and clinically interview European adolescents reporting current suicidality (suicidal ideation and suicide attempt) and investigate attendance at the clinical interview. The Saving and Empowering Young Lives in Europe (SEYLE) Project was carried out in 11 European countries. A baseline questionnaire was completed in school by 12,395 adolescents (mean age 14.9; SD 0.9). Those who screened positive for suicidality (attempting suicide and/or serious suicidal ideation or plans) in the past 2 weeks were invited to a clinical interview with a mental health professional. Of the 12,395 adolescents, 4.2 % (n = 516) screened positive for current suicidality. The prevalence ranged from 1.1 % in Hungary to 7.7 % in Israel (p attended the clinical interview. Female students were more likely to attend for interview (42.0 % versus 30.6 %, p = 0.010). The attendance rate varied considerably across countries, from 5.7 % in Italy to 96.7 % in France (p attendance was associated with using school as the only interview setting (Mean attendance rate, MAR = 88 vs. 31 %, p = 0.006) and arranging the interview within 1 week of contacting the student (MAR = 64 vs. 23 %, p = 0.013). The greater the travel time to interview, the lower the attendance rate (Pearson's r = -0.64, p = 0.034). Independent of the variation by country, at the individual level, adolescents with more depressive symptoms and a recent suicide attempt more often attended for interview. A high rate of current suicidality was found amongst European adolescents. However, the majority of these displayed limited help-seeking behaviour. Future studies should investigate ways of making screening programmes and other interventions more acceptable and accessible to young people, especially young males.

    2015-12-01

    Global Systems Science (GSS), a high school integrated interdisciplinary science project based at Lawrence Hall of Science at UC Berkeley, has collaborated with many organizations and institutions since its inception in the early 1990s. To start with, there were the federal agencies that made GSS possible: WESTGEC, NIGEC, NSF, and NASA. An NSF grant enabled the project to have teachers field test GSS in their classes and meet in summer institutes that resulted in GSS module dealing with climate change and related topics including energy use, ozone, loss of biodiversity, and ecosystem change. Interacting small and large systems naturally became an overarching theme. NASA grants and relationships with other NASA grantees in the NASA Innovations in Climate Education (NICE) program resulted in formation of Professional Learning Communities (PLCs) in the GSS Lifelines for High School Climate Change Education project. Teachers involved in that project participated in webinars with representatives of various climate change education resources, including SatCam, Detroit Climate Action Collaborative, Picture Post (UNH), Eyes on Earth, Earth Exploration Toolbook, My NASA Data, Digital Earth Watch (DEW), Alliance for Climate Education (ACE), the JPL Global Climate Change website, EOS-Webster (UNH), and Museum of the Earth at the Paleontological Research Institution. These webinars were recorded and are available at http://www.globalsystemsscience.org/lifelines/presentations.

    Grant, Jon E; Potenza, Marc N; Krishnan-Sarin, Suchitra; Cavallo, Dana A; Desai, Rani A

    2011-01-01

    Although shopping behavior among adolescents is normal, for some, the shopping becomes problematic. An assessment of adolescent shopping behavior along a continuum of severity and its relationship to other behaviors and health issues is incompletely understood. A large sample of high school students (n = 3999) was examined using a self-report survey with 153 questions concerning demographic characteristics, shopping behaviors, other health behaviors including substance use, and functioning variables such as grades and violent behavior. The overall prevalence of problem shopping was 3.5% (95% CI, 2.93-4.07). Regular smoking, marijuana and other drug use, sadness and hopelessness, and antisocial behaviors (e.g., fighting, carrying weapons) were associated with problem shopping behavior in both boys and girls. Heavy alcohol use was significantly associated with problem shopping only in girls. Problem shopping appears fairly common among high school students and is associated with symptoms of depression and a range of potentially addictive and antisocial behaviors. Significant distress and diminished behavioral control suggest that excessive shopping may often have significant associated morbidity. Additional research is needed to develop specific prevention and treatment strategies for adolescents who report problems with shopping. Copyright © 2011 Elsevier Inc. All rights reserved.

    2012-03-01

    Ethnically diverse high school contexts present unique social opportunities for youth to form interethnic relationships, but they may also subject students to certain social challenges such as peer ethnic discrimination. With a sample of 1,072 high school students (55% girls; 54% Latino, 20% African American, 14% Asian, 12% White) attending 84 high schools, school context factors that protect students' exposure to peer ethnic discrimination across the high school years were investigated with a three-level hierarchical linear model. Each spring for four consecutive years (grades 9-12), self-reported peer ethnic discrimination, interracial climate at school, and perceived school ethnic composition were assessed. At the school level, objective high school ethnic composition data were collected. Peer ethnic discrimination was found to decline slightly across the high school years. Above and beyond this decline, more positive perceptions of the school interracial climate and both objective and perceived numerical ethnic majority status predicted lower levels of peer ethnic discrimination. Taken together, the results highlight the significance of both objective (e.g., ethnic composition) and subjective (e.g., interracial climate) aspects of the school ethnic context to students' high school social experiences.

    Rao, Yuan; Deng, Wan-Ling; Huang, Jun-Kai

    2015-03-01

    A novel on-chip current sensing circuit with current compensation technique suitable for buck-boost converter is presented in this article. The proposed technique can sense the full-range inductor current with high accuracy and high speed. It is mainly based on matched current mirror and does not require a large proportion of aspect ratio between the powerFET and the senseFET, thus it reduces the complexity of circuit design and the layout mismatch issue without decreasing the power efficiency. The circuit is fabricated with TSMC 0.25 µm 2P5M mixed-signal process. Simulation results show that the buck-boost converter can be operated at 200 kHz to 4 MHz switching frequency with an input voltage from 2.8 to 4.7 V. The output voltage is 3.6 V, and the maximum accuracy for both high and low side sensing current reaches 99% within the load current ranging from 200 to 600 mA.

    The relationship between students’ school environment and exercise habits is complex, and is affected by numerous factors. However, the few studies that have been conducted on this relationship have reported inconsistent results, especially regarding Taiwanese students. We conducted this cross-sectional study to investigate the association of school environment and after-school physical activity with health-related physical fitness in Taiwanese adolescents. Data were drawn from a national survey conducted by the Ministry of Education in Taiwan in 2008 of health-related physical fitness measurements among junior high school students (649,442 total) in grades seven to nine. School environment (level of urbanization, school size, presence of sports field or gymnasium) and after-school physical activity were assessed for their association with adolescents’ physical fitness measurements (body mass index (BMI), bent-leg sit-ups, 800-/1600-m run, sit-and-reach, standing long jump). Urban boys and girls perform significantly better in muscle strength and endurance, cardiorespiratory endurance, flexibility, and explosive power; girls from rural areas exhibited significantly worse scores in body composition. Boys from large-size schools performed the worst in cardiorespiratory endurance, flexibility, and explosive power; whereas girls from large-size schools performed the worst in muscle strength, muscle endurance, and explosive power, but had the best score for body composition. However, the differences in body composition of boys from large-, medium-, and small- size schools did not reach a statistically significant level. Adolescents of both genders in schools with a sports field or gymnasium exhibited significantly better in muscle strength and endurance, cardiorespiratory endurance, and explosive power.

    Face-to-face contacts between individuals contribute to shape social networks and play an important role in determining how infectious diseases can spread within a population. It is thus important to obtain accurate and reliable descriptions of human contact patterns occurring in various day-to-day life contexts. Recent technological advances and the development of wearable sensors able to sense proximity patterns have made it possible to gather data giving access to time-varying contact networks of individuals in specific environments. Here we present and analyze two such data sets describing with high temporal resolution the contact patterns of students in a high school. We define contact matrices describing the contact patterns between students of different classes and show the importance of the class structure. We take advantage of the fact that the two data sets were collected in the same setting during several days in two successive years to perform a longitudinal analysis on two very different timescal...

    Williams, A; McCartt, A; Geary, L

    2003-01-01

    Objective: To determine seatbelt use of teenage drivers arriving at high schools in the morning and at evening football games compared with belt use of adults driving teenage passengers to these events, and teenage passenger belt use depending on whether they were being driven by another teenager or an adult. Methods: Unobtrusive observations of belt use were made at 12 high schools in Connecticut and Massachusetts. Results: Among males, teenage drivers had lower belt use than adults; differences between female teenage and female adult drivers were slight. Teenage passengers had lower belt use in vehicles driven by other teenagers than in cars driven by adults, but more than 40% of teenage passengers in vehicles driven by adults, presumed in most cases to be the teenager's parent, were not belted. Teenage passenger belt use was lower than teenage driver use regardless of gender. These differences were found both at morning arrivals and at football games, but teenage belt use was not much different in these two settings. Teenage passengers were belted more often if drivers were belted, whether the driver was another teenager or an adult, but a third of male passengers and 25%–30% of female passengers were unbelted even when drivers were belted. Conclusion: Teenagers have high crash risk but low belt use, which adds to their injury problem. Avenues to address this include strong belt use laws and their enforcement, building belt use requirements into graduated licensing systems, keeping young beginners out of high risk driving situations, and finding ways to influence parents and other adults to ensure that their teenage passengers use seatbelts.

    Full Text Available This article discusses the results of a study of actual mental state of high school students who are active subjects of career self-determination in terms of interactive learning. There are four groups of methods of interactive training: psychological training, art therapy, cognitive, and game training. The main task, which is solved by a researcher in a formative experiment with the use of each of these methods, is to establish significant differences in health, activity and mood as the indicators of current mental state of students in the classroom. As a result, we found that the most significant improvements in the current mental state takes place when using art and game therapy, so these techniques should be used in groups of students with low motivation to work, as well as in the adverse psychological climate. Less significant was the improvement of the current mental state after psychological training due to the fact that this method allow to update and seek solutions to the most important intrapersonal issues and require the implementation of a deeper reflection

  19. The limitations of mathematical modeling in high school physics education

    Science.gov (United States)

    Forjan, Matej

    The theme of the doctoral dissertation falls within the scope of didactics of physics. Theoretical analysis of the key constraints that occur in the transmission of mathematical modeling of dynamical systems into field of physics education in secondary schools is presented. In an effort to explore the extent to which current physics education promotes understanding of models and modeling, we analyze the curriculum and the three most commonly used textbooks for high school physics. We focus primarily on the representation of the various stages of modeling in the solved tasks in textbooks and on the presentation of certain simplifications and idealizations, which are in high school physics frequently used. We show that one of the textbooks in most cases fairly and reasonably presents the simplifications, while the other two half of the analyzed simplifications do not explain. It also turns out that the vast majority of solved tasks in all the textbooks do not explicitly represent model assumptions based on what we can conclude that in high school physics the students do not develop sufficiently a sense of simplification and idealizations, which is a key part of the conceptual phase of modeling. For the introduction of modeling of dynamical systems the knowledge of students is also important, therefore we performed an empirical study on the extent to which high school students are able to understand the time evolution of some dynamical systems in the field of physics. The research results show the students have a very weak understanding of the dynamics of systems in which the feedbacks are present. This is independent of the year or final grade in physics and mathematics. When modeling dynamical systems in high school physics we also encounter the limitations which result from the lack of mathematical knowledge of students, because they don't know how analytically solve the differential equations. We show that when dealing with one-dimensional dynamical systems

    The large hadron collider (LHC) will be equipped with about 8000 superconducting magnets. Some 3380 leads will feed the currents ranging from 60 to 13000 A. To reduce the heat inleak into the liquid helium, CERN aims to use high temperature superconducting material for leads having current ratings between 600 and 13000 A. Specifications have been written for 13000 A current leads, incorporating a high temperature superconducting section, for the main of the LHC, and contracts have been placed with several firms for the supply of prototypes for comparative testing. The leads used for feeding locally the 60 and 120 A dipole orbit correctors will be conventional conduction cooledmagnets resistive leads. An optimized lead of variable cross section has been tested, and an integral design has been initiated. This report describes the design status of the current leads for the LHC, emphasizing, for the different solutions, the principle of optimization and the choice of cooling methods. (8 refs).

    Conditions for current instabilities that arise in high-temperature superconducting composites with essentially nonlinear dependences of the critical current densities and resistivity on the temperature and magnetic induction have been studied. The analysis has been conducted in terms of zero-dimensional models, which has made it possible to formulate general physical mechanisms behind the formation of currents states in superconducting composites according to the external magnetic field induction, cooling conditions, and the properties of the superconductor and cladding. The possible existence of current and temperature stable steps, as well as stable steps of the electric field strength, in the absence of the superconducting-normal transition, has been demonstrated. Reasons for instabilities under multistable current states have been discussed.

    2015-12-01

    Problem solving is a critical element of learning physics. However, traditional instruction often emphasizes the quantitative aspects of problem solving such as equations and mathematical procedures rather than qualitative analysis for selecting appropriate concepts and principles. This study describes the development and evaluation of an instructional approach called Conceptual Problem Solving (CPS) which guides students to identify principles, justify their use, and plan their solution in writing before solving a problem. The CPS approach was implemented by high school physics teachers at three schools for major theorems and conservation laws in mechanics and CPS-taught classes were compared to control classes taught using traditional problem solving methods. Information about the teachers' implementation of the approach was gathered from classroom observations and interviews, and the effectiveness of the approach was evaluated from a series of written assessments. Results indicated that teachers found CPS easy to integrate into their curricula, students engaged in classroom discussions and produced problem solutions of a higher quality than before, and students scored higher on conceptual and problem solving measures.

    A counterpulse technique for the controlled interruption of very high currents in inductive storage pulsed power systems is described and analyzed, and some simulation results of its performance are presented. The accompanying circuit comprises a pre-charged capacitor bank, connected in series with the inductive load, which has to be provided with a current pulse. Upon actuation, a resonant counterpulse current is created in the opening switch, connected in parallel with the current source and the load. In this way, the opening switch is opened at low current. A separate closing switch prevents closing of the opening switch at high voltage. Operation of the opening switch, often a mechanical switch, at low current and low voltage prevents arc erosion of the contacts. The advantage of this circuit compared to other counterpulse circuits is that the capacitor bank does not experience a voltage reversal. Electrolytic capacitors, which have a high energy density, are applied. The remaining energy of the capacitor bank after opening the opening switch, is transferred to the load. The required initial voltage of the capacitor bank is only a few hundred volts, whereas it may be above a kilovolt in other circuits. Another advantage of the method described here is that the load does not experience a pre-current, causing unwanted preheating of the load, before the resonant current is activated. At the moment, work is being performed at the Pulse Physics Laboratory to develop the resonant series counterpulse circuit for use with rail accelerators, which must be supplied with current pulses in the millisecond range up to the mega-ampere level.

    Conventionally, turbidity currents are considered as fluidal flows in which sediment is supported by fluid turbulence, whereas debris flows are plastic flows in which sediment is supported by matrix strength, dispersive pressure, and buoyant lift. The concept of high-density turbidity current refers to high-concentration, commonly non-turbulent, flows of fluids in which sediment is supported mainly by matrix strength, dispersive pressure, and buoyant lift. The conventional wisdom that traction carpets with entrained turbulent clouds on top represent high-density turbidity currents is a misnomer because traction carpets are neither fluidal nor turbulent. Debris flows may also have entrained turbulent clouds on top. The traction carpet/debris flow and the overriding turbulent clouds are two separate entities in terms of flow rheology and sediment-support mechanism. In experimental and theoretical studies, which has linked massive sands and floating clasts to high-density turbidity currents, the term high-density turbidity current has actually been used for laminar flows. In alleviating this conceptual problem, sandy debris flow is suggested as a substitute for high-density turbidity current. Sandy debris flows represent a continuous spectrum of processes between cohesive and cohesionless debris flows. Commonly they are rheologically plastic. They may occur with or without entrained turbulent clouds on top. Their sediment-support mechanisms include matrix strength, dispersive pressure, and buoyant lift. They are characterized by laminar flow conditions, a moderate to high grain concentration, and a low to moderate mud content. Although flows evolve and transform during the course of transport in density-stratified flows, the preserved features in a deposit are useful to decipher only the final stages of deposition. At present, there are no established criteria to decipher transport mechanism from the depositional record.

    Recently, a phenomenon known as sexting, defined here as the transfer of sexually explicit photos via cell phone, has received substantial attention in the U.S. national media. To determine the current and potential future impact of sexting, more information about the behavior and the attitudes and beliefs surrounding it must be gathered, particularly as it relates to sexting by minors. The present study was designed to provide preliminary information about this phenomenon. Participants were 606 high school students (representing 98 % of the available student body) recruited from a single private high school in the southwestern U.S. Nearly 20 % of all participants reported they had ever sent a sexually explicit image of themselves via cell phone while almost twice as many reported that they had ever received a sexually explicit picture via cell phone and, of these, over 25 % indicated that they had forwarded such a picture to others. Of those reporting having sent a sexually explicit cell phone picture, over a third did so despite believing that there could be serious legal and other consequences attached to the behavior. Given the potential legal and psychological risks associated with sexting, it is important for adolescents, parents, school administrators, and even legislators and law enforcement to understand this behavior.

    Full Text Available Based on the production and disappearance of ions and electrons in the high power impulse magnetron sputtering plasma near the target, the expression of the discharge current is derived. Depending on the slope, six possible modes are deduced for the discharge current and the feasibility of each mode is discussed. The discharge parameters and target properties are simplified into the discharge voltage, sputtering yield, and ionization energy which mainly affect the discharge plasma. The relationship between these factors and the discharge current modes is also investigated.

    Microstructural defects are the primary determining factors for the values of critical-current densities in a high {Tc} superconductor after the electronic anisotropy along the a-b plane and the c-direction. A review is made to assess firstly what would be the maximum achievable critical-current density in YBa{sub 2}Cu{sub 3}O{sub 7} if nearly ideal pinning sites were introduced and secondly what types of pinning defects are currently introduced or exist in YBa{sub 2}Cu{sub 3}O{sub 7} and how effective are these in pinning vortices.

    Internal current collection efficiencies greater than 90% and energy conversion efficiencies of 18 % at 30 suns were measured on a laboratory version of the interdigitated back contact (IBC) solar cell. A phosphorous gettering diffusion was performed on the front surface and then etched off to achieve these high current collection efficiencies. Thermal oxides were grown on the front and back of the cell to passivate the silicon surfaces. Although the internal collection efficiencies of the cell were high, series resistance caused the fill factor (FF) to decrease at concentrations above 30 suns. Dark current measurements on cells with a new grid spacing indicate that the series resistance is much lower than in the previous cell design. It is suggested that this should result in higher efficiencies at high concentration.

    We developed an education module on nuclear forensics, designed for high school science classrooms. The lessons include a mix of hands-on activities, computer simulations, and written exercises. Students are presented with realistic scenarios designed to develop their knowledge of nuclear science and its application to nuclear forensics. A two-day teacher workshop offered at Hope College attracted 20 teachers. They were loaned kits to implement activities with their students, and each teacher spent 3--7 days on the lessons. All who reported back said they would do it again and would share the lessons with colleagues. Many said that access to equipment and ready-made lessons enabled them to expand what they taught about nuclear science and introduce nuclear forensics. A few teachers invited guest speakers to their classroom, which provided an excellent opportunity to share career information with students. We acknowledge generous support from the Department of Homeland Security and the AIP Meggars Award.

    The Lifelines project aims to establish a network of practicing high school teachers actively using climate change curricula by creating professional learning communities (PLCs) of teachers who, through remote meetings and workshops, maintain ongoing communication and sharing of best practices among colleagues to strengthen knowledge and promote effective teaching strategies. The project explores techniques to achieve the most effective teleconferencing meetings and workshops. This promotes not only teaching about minimizing environmental impacts of human activity, but minimizes environmental impacts of professional development — practicing what we preach. To date, Lifelines PLCs have set up websites and e-mail lists for sharing information. Teleconferences and webinars have been held using services such as Skype, ReadyTalk, and Wiggio. Many of the meetings have been recorded and archived for the benefit of members who could not attend in real-time.

    Full Text Available The recent spread of technological innovation along with the sophistication of the ICT gadgets have shapped and transformed the realm of learning and teaching including in that of English Language. Alongside, ICT has become more and more inextricable part of human businesses and put a higher level of demand for technological literacy in the part of English learners in order for them to be convident in the digital era membership and participation. This study surveyed 400 high school students as regards: (a their ICT gadgets perceived ownership; (b their day-to-day outside and in-school use and; (c their activities using ICT gadgets for English learning. Findings from the descriptive analyses of the mixed-method study, disclose the positive perception about the gadget ownership. Interestingly, the current study also discovers that there has been a mismatch between the positively perceived ownership of the ICT gadgets and the real day-to-day use as facilitative media for learning, in particular as a useful aids for English language learning. Focusing on the result discussion, issues with regard to discrepancies in the provision of infrastructures and the lack of the support system by school institutions emerge from the FGD analysis highlighting the importance for all decision makers, school institutions, and teachers to consciously start doing something about it. By highlighting the pivotal role of the technology, the researcher suggested a real action for responding to the call for a change in both policy makers and institutonal levels to start integrating the technology into the school curricula.
