Opportunities for Professional Learning in Mathematics Teacher Workgroup Conversations: Relationships to Instructional Expertise     

Ilana Seidel Horn  Britnie Delinger Kane 《学习科学杂志》2015,24(3):373-418

Increasingly, instructional improvement efforts include teacher communities as part of their overall strategy, yet the relationship between teachers’ talk and professional learning remains underspecified. Using a discourse perspective on learning, this article compares opportunities to learn (OTLs) in the collaborative conversations of 3 mathematics teacher workgroups. We examined the differences in OTLs in 17 hr of videotaped meetings from 3 groups at different levels of instructional accomplishment in secondary mathematics. Using mixed methods, we uncovered differences in the groups’ interactions and found that OTLs were not equally distributed. Instead, teacher groups whose active participants demonstrated the greatest facility with ambitious instruction also had the richest conversational OTLs. We interpret this as an accumulated advantage developmental story: Because collaborative work in teaching involves problem posing and the articulation of practice, teachers’ conceptions get built into the framing and discussion of pedagogical problems. Accomplished teachers are thus positioned to learn more from talking with colleagues. This analysis contributes to understanding of how OTLs are constituted in teacher workgroups, with implications for making better use of teacher collaboration for professional learning.  相似文献   

Face-to-face versus computer-mediated discussion of teaching cases: Impacts on preservice teachers’ engagement, critical analyses, and self-efficacy

Two frequently-used discussion protocols were investigated as part of a program to implement teaching cases in undergraduate educational psychology classes designed for preservice teachers. One protocol involved synchronous face-to-face (FTF) discussion of teaching cases, which occurred in class after students had individually completed written case analyses as homework outside of class. The other was asynchronous computer-mediated (CM) discussion taking place outside of class, simultaneous to students’ completion of their written case analyses. Six class offerings of an undergraduate child development course taught by two instructors (three classes by each instructor) were randomly assigned within instructor in a quasi-experimental design to one of the three discussion conditions: FTF, CM, or no discussion of the cases across the semester. Findings indicated that both CM and FTF discussion conditions were associated with positive outcomes relative to the control condition. Both CM and FTF discussion related to higher cognitive–affective engagement with the cases than the control condition; and the CM discussion condition was associated with higher cognitive–affective engagement than FTF discussion. In contrast, FTF discussion, but not CM discussion, was associated with higher-than-control-condition case analysis ability at the end of the semester. Potential explanations for these findings and directions for future research are discussed.  相似文献

Adolescent sexual risk behaviors and school‐based sexually transmitted infection/HIV prevention     

Christy M. Walcott  Adena B. Meyers  Steven Landau 《Psychology in the schools》2008,45(1):39-51

Many adolescents are susceptible to negative outcomes associated with sexual behavior. This is particularly true for those who initiate sexual intercourse at an early age, have many sex partners, or engage in unprotected sex because these behaviors put one at risk for sexually transmitted infections (STIs), including HIV. This article reviews the various demographic, social‐contextual, and intrapersonal factors linked to sexual risk behaviors. Successful STI/HIV prevention programs must consider developmental and gender issues, as well as cultural norms and values, to effectively meet the prevention needs of all adolescents. We discuss the characteristics of effective intervention programs and provide the names and key features of empirically validated, school‐based STI/HIV prevention programs. In addition, we recommend specific roles for school psychologists in STI/HIV prevention efforts. Finally, other resources are provided to assist practitioners in their continuing review of STI/HIV prevention education. © 2007 Wiley Periodicals, Inc.  相似文献   

Introducing teaching cases with face-to-face and computer-mediated discussion: Two multi-classroom quasi-experiments     

Roger Bruning  Kamau O. Siwatu  Xiongyi Liu  Lisa M. PytlikZillig  Christy Horn  Stephanie Sic  Deborah Carlson 《Contemporary educational psychology》2008,33(2):299-326

Two studies were conducted in multisection introductory child and adolescent development classes to determine effects of introducing abbreviated teaching case studies that were then discussed either in face-to-face or online formats. Students receiving teaching case studies in either format in both classes showed improved ability to critically analyze probe and final cases compared to control participants. Both case study groups in the child development class also showed increased application of psychological concepts in analyzing new cases. No differences in course knowledge were expected as a function of condition and none were found. Hypothesized case-related increases in efficacy for teaching also were not observed. Results were interpreted as supporting a case analysis approach in educational psychology classes and use of online methods for presentation and discussion of abbreviated cases.  相似文献   

Narrative transportability,leisure reading,and genre preference in children 9–13 years old     

Jakob D. Jensen  Katheryn Christy  Melinda Krakow  Kevin John  Nicole Martins 《The Journal of educational research》2016,109(6):666-674

Leisure reading behavior is a key predictor of educational success. Transportability is a trait that determines how likely an individual is to become involved in a story, and past research has suggested that involvement may be related to leisure reading behavior. However, available measures of transportability have not been validated with children or related to leisure reading. To address this gap, children 9–13 years old (N = 136) completed a revised version of the Transportability Scale. A 13-item version of the scale was found to be unidimensional, reliable, and predictive of 6% of the variance in leisure reading (above and beyond sex, age, reading ability, and student performance). Transportability was also related to genre preference and several interesting sex differences emerged. The Transportability Scale provides researchers with a psychometrically sound measure of narrative involvement to advance research on leisure reading.  相似文献   

The Impact of Changing Roles on Relationships between Professionals in Inclusive Programs for Young Children

As inclusion of young children with disabilities into preschool programs has become more prevalent, there have been concomitant changes in the roles assumed by the professionals and paraprofessionals in these programs. In this paper we examine the ways in which inclusive models influence the roles assumed by the program staff and the factors that affect the ability of staff members to assume these roles. Data, which included interviews, participant observation and document analysis, were collected as part of a multi-site national study of inclusive education programs and practices. From these data, themes emerged regarding the changing roles and relationships of staff members in inclusive early childhood programs. These themes are discussed as both facilitators of and barriers to successful inclusive programs.  相似文献
