Most teacher preparation programs have embraced the use of video as an effective methodology for developing teachers’ noticing skills. This study focused on learning about what secondary mathematics prospective teachers (PSTs) were able to notice when viewing video of their own co-teaching, particularly in a microteaching setting that consisted of peers. PSTs documented their observations on an observation tool while re-watching their video and then identified and ranked their top three observations. The ranked noticing statements were analyzed based on a grounded theory approach. Overall, PSTs’ ranked observations were more likely to attend to students and had a strong focus on mathematics and student learning. Ranked observations equally demonstrated both broad and specific understanding of video moments and often made suggestions that something they noticed could be improved in the implementation stage, versus improvements in planning or changes in themselves. Results support PSTs’ use of video for developing noticing skills in teacher education programs. 相似文献

ABSTRACTStereotypes people hold about computer scientists contribute to underrepresentation in computer science. Perceptions of computer scientists have historically been linked to males and a “nerd” culture, which can lead to lack of interest, particularly for girls. This article presents two studies conducted with two groups of middle schoolers: those who attended our programming camp (Study One) and those who did not (Study Two). After analyzing participants’ drawings and two survey questions we found that perceptions youth holds about computer scientists may be improving. Additionally, we found that males (versus females) and those youth who did not attend our camp (versus those who did) tended to have more stereotypical perceptions of computer scientists. With this article, we contribute to the literature on CS stereotypes by examining both positive and negative representations youth had about computer scientists. We also cast light on the lack of awareness about this profession among the youth of this age. 相似文献

The inadequate number of American young adults selecting a scientific or engineering profession continues to be a major national concern. Using data from the 23-year record of the Longitudinal Study of American Youth (LSAY) and working within the social learning paradigm, this analysis uses a set of 21 variables to predict young people's employment in science, technology, engineering, mathematics, or medicine (STEMM) at ages 36 to 39. The LSAY is one of the longest and most intensive longitudinal studies of the impact of secondary education and postsecondary education conducted in the United States. Using a structural equation model, the study found that mathematics continues to be a primary gateway for STEMM professions, beginning with algebra track placement in grade eight and continuing through high school and college calculus courses. Home and family factors such as parent education and parent encouragement of science and mathematics during secondary school also enhanced the likelihood of entering a STEMM profession. 相似文献

This article discusses historical and contemporary influences on changes in special education assessment, with emphasis on three persistent themes: accurate classification, fairness to minority students, and special education outcomes. Dunn's contributions to each of the themes are discussed, along with other influences such as legislation and litigation. Current dynamics leading to significant changes in special education assessment are discussed, particularly in the disability category of specific learning disabilities. 相似文献

Gary Rhodes, Albert Biscarra, Lisa Loberg, and Katie Roller suggest that the next steps to improve study‐abroad programs are to increase the diversity of student participants and partner with departments across the academic and student affairs spectrum. 相似文献
