This study examines the nature of teacher participation in the context of a video club. Video clubs are professional development meetings in which teachers watch and discuss excerpts of video from their classrooms. In this study, I adopt a situative perspective to examine how teachers develop in their participation to accomplish the goals of the video club. In particular, I examine the roles participants play and explore teachers' participation in four roles that correspond with key goals of the video club. Analysis revealed that teachers' participation shifted in qualitatively different ways over time, with the teachers coming to prompt the group to discuss student mathematical thinking, to propose a variety of interpretations of student ideas, to build on one another's ideas, and to challenge one another's thinking in order to advance the group's conversations. This analysis suggests that the group learned how to participate in roles central to accomplishing the goals of the video club. Studying teacher learning through a lens of participation provides insight into the ways in which teachers coordinate themselves to engage with the goals of professional development and has implications for designing professional development that helps teachers develop practices for teaching mathematics for understanding.  相似文献

Using a teacher recruitment and preparation model, a unique partnership between PK–12 schools, a community college, and a university is examined. The focus is on the training and credentialing of future educators, particularly from underrepresented backgrounds, in an efficient and quality manner to assist in meeting the current PK–12 teacher shortage. Data indicate that the partnership is progressing towards, or has met, its targets in addressing said shortage.  相似文献

Institutional and student level data from the Florida Community Colleges were examined to explore the Retention Index of the Community College Survey of Student Engagement (CCSSE). A simple correlation and regression analysis was conducted to determine if the CCSSE Retention Index could be used to predict the institutional retention rate calculated for the state accountability measure. Student level data were used with a nested ANOVA to examine if there were mean differences in the CCSSE Retention Index scores of males and females of different racial groups when accounting for the potential influence of the institution attended. Mean differences were examined since differences in retention rates of these groups have been documented.  相似文献

It is generally accepted that engineering requires a strong aptitude for mathematics and science; therefore, students’ judgments regarding their competence in these areas as well as engineering likely influence their confidence in engineering. Little is known about how self-confidence in science, mathematics, and engineering courses (STEM confidence) varies at the intersection of race/ethnicity and gender. To fill this gap, this study examined the STEM confidence of multiple groups in undergraduate engineering programs. Results indicated that although some underrepresented groups may have lower STEM confidence overall, this finding no longer applies to all groups after controlling for personal, environmental, and behavioral factors. Specifically, African-American and Hispanic men report higher average STEM confidence than White men after controlling for these associated measures. In addition, White women continue to report lower average STEM confidence than White men after controlling for these measures, while other groups do not differ from White men. Further, many elements of student perception, including student views of professors, comparisons to peers, perceptions of the field as rewarding, and desirability of chosen major are positively associated with student STEM confidence. The changing patterns of significance for race/ethnicity and gender groups between the two models indicate that personal, environmental, and behavioral factors have different relationships with STEM confidence levels for different groups. This study contributes an understanding that gender differences in STEM confidence are not indifferent to racial and ethnic context. Social-cognitive theory provides a valuable framework for studying student academic confidence and would improve future self-confidence research.  相似文献

The goal of this qualitative 2-year study was to examine the resilience building process in four novice secondary science teachers and its link to teacher retention. To achieve the research goal, a resilience framework was established. Three factors were instrumental in creating the framework. The first focused on stressors and protective factors in the lives of novice secondary science teachers and provided direction and goals for the research. Second, a case study was developed for each of the four teachers participating in the research in order to emphasize the detailed analysis of factors linked to resilience. Finally, cross-case analysis was employed to identify similarities and differences and provide insight into issues concerning the resilience process. Results of this study suggest that the interaction between stressors and protective factors acts as a primary force in the resilience process and stimulate responses to help counteract negative effects of resulting stress. Therefore, it can be reasoned that resilience can be fostered in novice teachers as a means to encourage teacher retention.  相似文献
