媒介素养教学方法和教师培训

由于全球文化急剧变化以及素养在提高个人、社会和文化发展中的作用,如今的素养概念已经扩展为包括数字、视觉和电子媒介以及流行文化在内的一种内涵;这也就提升了媒介素养教育对个人和社会发展的重要意义。开展媒介素养教育可以在正规和非正规教育环境下进行,它将对学生学习动机的激发、师生关系的改善、公民技能的提高产生作用。     

Multi-candidate reduction: Sentence compression as a tool for document summarization tasks

This article examines the application of two single-document sentence compression techniques to the problem of multi-document summarization—a “parse-and-trim” approach and a statistical noisy-channel approach. We introduce the multi-candidate reduction (MCR) framework for multi-document summarization, in which many compressed candidates are generated for each source sentence. These candidates are then selected for inclusion in the final summary based on a combination of static and dynamic features. Evaluations demonstrate that sentence compression is a valuable component of a larger multi-document summarization framework.     

Factors affecting placement decisions of children following short-term emergency care

Case files of 424 residents at an emergency treatment center for abused and neglected children were used to generate a beginning set of variables which, in combination, predicted whether or not children from the center would be discharged to their natural family environment. Variables with descending order of predictive significance were place from which the child was admitted, the length of time spent in treatment, the age and the race of the child, Other variables--the number of siblings, the child's sex and the presence of physical/sexual abuse--did not approach significance.     

An Evaluation of Three Interdisciplinary Social Science Events Outside of the College Classroom

This article describes three interdisciplinary events held outside of the classroom to examine social psychological concepts in the criminal justice system, with undergraduate students enrolled in criminal justice and psychology courses. These events can most accurately be described as using a synthetic interdisciplinary approach, in which the disciplines of psychology and criminal justice remain clearly identifiable in looking at phenomena like occurrences of bystander apathy, while enabling a holistic view of these phenomena. First, 75 students celebrated the life of Kitty Genovese, a famous victim of bystander apathy. Later in the semester, the same students competed in a game-show-like review session. Finally, 45 students explored the intersection of the mental health and criminal justice systems with professionals from various fields. Overall, students enjoyed the social interaction with their peers across the majors, as well as with their professors and professionals in the field. Students also indicated that the interactive learning techniques enhanced their new understanding of the intersection of the disciplines. Future research should investigate the offering of interdisciplinary events to students within and across academic divisions to build community and enhance students' understanding of their educational and career opportunities.     

An international collaborative investigation of beginning seventh grade students' understandings of scientific inquiry: Establishing a baseline

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.     

Statistical estimates of learners�� judgments about knowledge in calibration of achievement

In theoretical models of self-regulated learning, calibration is one important component in successful learning. Two issues of calibration are explored. First, Nelson (1987) suggested the G (gamma) coefficient is the most appropriate measure of calibration (judgment accuracy) and rejected signal detection theory’s d′ statistic because data commonly challenge distributional assumptions. We empirically examined this issue, comparing G and d′. Second, we examined whether a learner’s calibration varies across three domains of knowledge: general, word, and mathematics. A sample of 266 university students volunteered to participate in the study. Participants were selected from various undergraduate and graduate courses. Participants first answered demographic items. Then they completed three knowledge tests (general, word, and mathematics) and judged correctness for each answer provided. Order of domains was randomly counterbalanced among participants. Results show that d′ is a valid measure of calibration, that assumptions about underlying distributions can be tested, and that preliminary evidence suggests that d′ may be a superior measure of accuracy compared to G. Finally, calibration varied by domain.     

The introduction of a medical informatics course into a medical school curriculum

Fulfilling the need for a course in medical informatics to be taught to medical students requires an effort on the part of the teaching faculty and administration. Creators of the curriculum must take into account contemporary pedagogical trends and the direction of medical education. Producing a course of study requires a firm conviction that practicing medicine in the 21st century demands currency, accuracy, and literacy with the available information sources.

Why are Women Underrepresented in Elite Colleges and Universities? A Non-Linear Decomposition Analysis

The emerging female advantage in education has received considerable attention in the popular media and recent research. We examine a persistent exception to this trend: women’s underrepresentation in America’s most competitive colleges and universities. Using nationally generalizable data spanning four decades, we evaluate evidence for three possible explanations. First, we analyze whether men’s academic profiles more closely match the admissions preferences of elite institutions. Next, we consider organizational preferences for male applicants. Finally, we test whether women self-select out of elite institutions through their application choices. Using Blinder–Oaxaca non-linear decomposition techniques and multinomial logistic regression, we find that men’s advantage in standardized test scores best explains the enrollment gap. Our analyses thus suggest that the gender enrollment gap in elite colleges and universities is a matter of access, not student choice. We discuss the implications of these results for educational equity and college admissions.
