Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed. 相似文献

Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the Introductory Biology I class is associated with even more dramatic gains among students from underrepresented minority populations than the gains found among their peers. These gains do not seem to be the product of better students availing themselves of supplemental instruction or other outside factors. The Introductory Biology I class consists of a team-taught lecture component, taught in a large lecture classroom, and a laboratory component where students participate in smaller lab sections. Students are expected to master an understanding of basic concepts, content, and vocabulary in biology as well as gain laboratory investigation skills and experience applying scientific methodology. In this context, supplemental instruction classes are cooperative learning environments where students participate in learning activities that complement the course material, focusing on student misconceptions and difficulties, construction of a scaffolded knowledge base, applications involving problem solving, and articulation of constructs with peers. 相似文献

Traditionally, citation count has served as the main evaluation measure for a paper's importance and influence. In turn, many evaluations of authors, institutions and journals are based on aggregations upon papers (e.g. h-index). In this work, we explore measures defined on the citation graph that offer a more intuitive insight into the impact of a paper than the superficial count of citations. Our main argument is focused on the identification of influence as an expression of the citation density in the subgraph of citations built for each paper. We propose two measures that capitalize on the notion of density providing researchers alternative evaluations of their work. While the general idea of impact for a paper can be viewed as how many researchers have shown interest to a piece of work, the proposed measures are based on the hypothesis that a piece of work may have influenced some papers even if they do not contain references to that piece of work. The proposed measures are also extended to researchers and journals. 相似文献

This paper reviews research on students’ usage of university counselling services across countries and their demographic and
psychological characteristics. In doing so, emphasis is given to reported distinctions between local and international university
students. Utilisation rates, encouraging factors and barriers to utilisation, presenting problems, and methodological problems
with existing studies are each examined. The findings suggest that only a minority of between 2% and 4% of university students
access such services, with females being more likely to use them than males. International students in particular underutilise
these services, and this is primarily due to such students’ preference for seeking help from family or friends over outside
sources. When students do seek assistance, their presenting issues most commonly involve symptoms of depression or anxiety,
as well as academic and relationship difficulties. 相似文献

This study moves in the space between two fields: science and technology studies (STS) and childhood studies; it thus belongs to the broader STS literature that investigates everyday practices outside the laboratory. The interpretation of ethnographic and bibliographic data on contemporary cardiovascular and obesity prevention in German kindergartens makes evident that when knowledge travels from biomedical laboratories to the preschool, then psychology comes into play! Bodies of knowledge such as behavioural or cognitive theories shape prevention and intervention practices, which could be seen as originally resulting from biomedical findings and trends. Accompanying this development is a change in the primary sciences that deal with childhood: these are no longer pedagogy or developmental and educational psychology (at least in their traditional forms), but ‘developmental science’. All this shapes contemporary childhood in quite normative ways. It thus remains an open question what non- or less normative institutional practices and bodies of knowledge could look like. 相似文献
