A set of practical exercises is reported, used with students in illustration of the unconscious biases of TV presentation techniques upon the viewer. The development of media studies work of this type is discussed, and its outcome for the students is illustrated by extracts from their written reports. The article is intended primarily for teachers of media and television studies, exemplifying an experimental approach made possible by the use of simple video equipment at various levels of education. 相似文献

In this article, the author explores the "algebra for all" issue to raise awareness about the many facets of this dilemma facing educators at the middle and high school levels. She discusses both sides of this controversial issue, especially regarding its impact on students' futures relative to higher education and employment. The author concludes that unless dramatic reform occurs in the delivery of algebra so that all students benefit from such instruction, students must make the decision to take algebra based on individual needs, interests, and desires. 相似文献

A multimedia game was designed to serve as a dual-purpose intervention that aligned with National Science Content Standards, while also conveying knowledge about the consequences of alcohol consumption for a secondary school audience. A tertiary goal was to positively impact adolescents' attitudes toward science through career role-play experiences within the game. In a pretest/delayed posttest design, middle and high school students, both male and female, demonstrated significant gains on measures of content knowledge and attitudes toward science. The best predictors of these outcomes were the players' ratings of the game's usability and satisfaction with the game. The outcomes suggest that game interventions can successfully teach standards-based science content, target age-appropriate health messages, and impact students' attitudes toward science. 相似文献

Online lectures have been used in lieu of live lectures in our gross anatomy and embryology course for the past eight years. We examined patterns of online lecture use by our students and related that use to academic entry measures, gender and examination performance. Detailed access records identified by student were available from server logs. Total views per page of lecture material increased over the first six years, then decreased markedly between years seven and eight, possibly due to the recent availability of alternate forms of lecture audio. Lecture use peaked in midafternoon and again in the evening, although some use was seen at all hours. Usage was highest at midweek and lowest on Fridays as might be expected. Individual student's use varied widely from rates equivalent to less than one viewing/page to more than three viewings per page. Overall use by male students was greater than that of females and gender‐specific differences in the daily pattern were seen. Lecture use was correlated to the Medical College Admission Test® (MCAT®) Verbal Reasoning and Physical Sciences scores but not to composite MCAT scores or undergraduate grade point average. Overall use appeared to be driven by scheduled team‐based learning (TBL) sessions and major examinations. Specific subsets of lecture material were most often viewed before related TBL sessions and again during review for examinations. A small but significant correlation between lecture use and examination and course performance was seen, specifically in the male student population. These findings, along with earlier observations, suggest that varied use of online lectures is attributable to multiple factors. Anat Sci Educ © 2012 American Association of Anatomists. 相似文献

Medical students at the Schulich School of Medicine and Dentistry at The University of Western Ontario in London, Ontario, Canada, learn clinical facts about the hepatobiliary system as transplant surgeon Dr. Vivian McAlister (at the far right) demonstrates Whipple's procedure in the anatomy laboratory. In this issue of ASE, Ullah and colleagues describe an extracurricular student initiative known as the Surgically Oriented Anatomy Program (SOAP), which aims to deliver anatomy teaching from a surgical perspective through the philosophy of “education through recreation”. 相似文献

This paper reports on a project aimed at identifying and exploring the development and implementation processes of teaching practices with interactive whiteboards (IWBs) in two Swedish K-6 schools. The purpose of the project was to generate results and insights of value when preparing student teachers for professional use of IWBs and to give school leaders guidelines when implementing IWBs. A range of methods were used to collect rich and varied empirical materials in this exploratory project. Judging from our data, it was obvious that the implementation process of IWBs, just like other information and communication technology initiatives, is very technology-oriented, but also dependent on attitudes. Over the course of time in the project, different strategies emerged among the teachers regarding whether and how they used the IWBs in their lectures. It also became increasingly clear during the study that there is a distinction between technical interactivity and pedagogical interactivity. Our results further suggest that training is needed when introducing these boards for future users. This training should include both technical instructions and pedagogical discussions. 相似文献
