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

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   

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

Retrospective on educational testing and assessment in the 20th century   总被引：3，自引：2，他引：1

Over the last 100 years, the ever-increasing demand for testing as a measure of educational reform has created a very profitable market for the US testing industry. We follow the growth of this market since the 1900s in two different, but related, ways. First, we discuss some of the technical developments that have encouraged the use of standardized testing in general and contributed to the growth of the commercial testing industry. Second, we attempt to quantify the expansion of the testing marketplace during the 20th century by tracking several indirect indices of growth over time. We conclude that although technical innovations may have contributed to the growth of the US testing marketplace, they do not necessarily lead to better tests or better outcomes for those who use them. There is a need to more carefully monitor the effects of these tests on teaching and learning in general, particularly when the tests are used in high-stakes contexts.  相似文献   

PUSH(ing) Limits: Using Fiction in the Classroom for Human Behavior and the Social Environment     

Natasha S. Mendoza  Kimberly Bonta  Philip Horn  Erin Moore  Allison Gibson  David Simmons 《Journal of Teaching in Social Work》2013,33(4):376-391

The use of fiction and autobiography in social science course work has been shown to enhance students' learning experience. Using the novel PUSH, by Sapphire, we designed a curriculum supplement for the social work course, human behavior and the social environment (HBSE) that encourages students to integrate course content in an innovative way and enables them to apply the material to life-like situations. The HBSE supplement allows students to explore poignant and problematic issues that push them past intrapersonal and interpersonal limits. Classes are infused with energy and the critical consciousness of the students. Final projects are a systematic case study of a chosen character (or characters) in the book and are a testament to student critical thinking and creativity. Methods, assignments, and student experiences in an introductory BSW course are described.  相似文献
