Coenrollment for students who are deaf or hard of hearing: friendship patterns and social interactions

Third- and fourth-grade students in two separate classrooms--one a classroom with only hearing students and the other a coenrolled classroom with hearing, hard of hearing, and deaf students--were assessed to determine friendship patterns, attitudes, beliefs, and perceptions about sign language and deafness. Sociograms, interviews, and videotape analysis of the students' responses were done. Results suggest that hearing students in the coenrolled classroom had better sign language skills, a more positive attitude toward deafness, and an improved awareness of certain aspects of hearing loss (such as speech and amplification). Deaf and hard of hearing students' social acceptance was similar to that of their hearing peers.     

AN ASSESSMENT OF THE CONTENT OF MEDICAL PRACTICE IN THE UNITED STATES: PROFILES OF PHYSICIANS IN FIVE SPECIALITIES

The University of Southern California has conducted a series of 24 surveys of the professional activities of physicians and surgeons in the United States. The surveys encompass more than 10,000 respondents representing 65.8% of all practising physicians in the United States and its territories. Using a specially‐developed “log‐diary” recording instrument, these physicians reported data on the care they provided during hundreds of thousands of encounters with their patients. This article provides an exposition of the study's unique methodology, presents illustratative data for 5 of the 24 specialities surveyed (cardiology, family practice, general internal medicine, orthopaedic surgery and psychiatry), and discusses the study's relevance and implications for medical education.     

Data and graph interpretation practices among preservice science teachers

The interpretation of data and construction and interpretation of graphs are central practices in science, which, according to recent reform documents, science and mathematics teachers are expected to foster in their classrooms. However, are (preservice) science teachers prepared to teach inquiry with the purpose of transforming and analyzing data, and interpreting graphical representations? That is, are preservice science teachers prepared to teach data analysis and graph interpretation practices that scientists use by default in their everyday work? The present study was designed to answer these and related questions. We investigated the responses of preservice elementary and secondary science teachers to data and graph interpretation tasks. Our investigation shows that, despite considerable preparation, and for many, despite bachelor of science degrees, preservice teachers do not enact the (“authentic”) practices that scientists routinely do when asked to interpret data or graphs. Detailed analyses are provided of what data and graph interpretation practices actually were enacted. We conclude that traditional schooling emphasizes particular beliefs in the mathematical nature of the universe that make it difficult for many individuals to deal with data possessing the random variation found in measurements of natural phenomena. The results suggest that preservice teachers need more experience in engaging in data and graph interpretation practices originating in activities that provide the degree of variation in and complexity of data present in realistic investigations. © 2005 Wiley Periodicals, Inc.

Effects of visual grouping strategies of computer-animated presentations on selective attention in science

The effects of visual grouping strategies involving animated and static graphic presentations on selective attention were studied. Also studied was the ability of students to learn a scientific rule presented incidentally in an animated sequence. A total of 39 fourth-graders participated in an introductory lesson on Newton's laws of motion. Two levels of Visual Presentation (Static Graphic, Animated Graphic) were crossed with two levels of Visual Grouping (Grouped, Ungrouped). A within-subjects factor consisted of two levels of Learning Intent (Intentional, Incidental). Results showed that students given animated presentations of lesson content outperformed students receiving static presentations, but only when the animated lesson frames were presented in groups, or “chunks,” of textual and visual sequences. Results also showed that students were able to successfully extract information pertaining to an application of Newton's second law incidentally presented in animated sequences. These latter results replicate earlier findings.     

Men’s and Women’s Intentions to Persist in Undergraduate Engineering Degree Programs

This is a quantitative study of 493 undergraduate engineering majors’ intentions to persist in their engineering program. Using a multiple analysis of variance analysis, men and women had one common predictor for their intentions to persist, engineering career outcome expectations. However, the best sociocognitive predictor for men’s persistence was not the same for women. Men’s persistence in undergraduate engineering was predicted by their abilities to complete the required coursework. Women’s persistence in undergraduate engineering depended upon their beliefs in getting good grades (A or a B). In brief, women’s intentions to persist in undergraduate engineering were dependent upon higher academic standards compared to men.
