Research suggests that professional development that engages teachers in instructional inquiry over an extended time through collaborative professional learning communities (PLCs) is effective in improving instruction and student achievement. Still, most professional development is offered as short-duration workshops that are not effective in changing practice. Barriers to the implementation of PLCs include lack of shared meeting time and a shortage of teachers who share the same subject areas or common goals and interests. Convening teachers from multiple districts can alleviate this problem, but teachers are reluctant to travel for meetings due to time and cost restraints. Video-conferencing software offers a solution to these barriers while serving to foster the sense of community needed for PLCs to be effective. The researchers describe the use of Virtual PLCs in which two groups of teachers met monthly for one school year to collaboratively analyze evidence collected as part of their teacher inquiry plans. With help from a facilitator, these groups developed a relationship similar to other groups meeting face-to-face as part of the same professional development program. Analysis of the reflections of teacher-participants and facilitators revealed that teachers prefer face-to-face meetings, but that the virtual and face-to-face meetings provided teachers with similar social interactions in the PLC experience. The findings suggest that teachers perceive videoconferencing as an effective tool for facilitating PLCs when distance and time are practical barriers to face-to-face meetings. Practical considerations for developing and facilitating virtual PLCs are also discussed.  相似文献

This is a design study meant to demonstrate the feasibility of integrating three rather different theoretical perspectives for future efforts in multimedia instructional design. A multimedia instructional grammar program contextualized within the teaching of English as a Second Language (ESL) was developed and evaluated. The program design was grounded in Mayer’s multimedia learning theory (2001), Sweller’s cognitive load theory (CLT, 2005), and cognitive training theory using an inductive reasoning paradigm (Klauer and Phye, Rev Educ Res 78(1):85–124, 2008). A successful integration of cognitive training theory into program design is expected to facilitate the transition of student’s declarative knowledge of a grammar concept of passive voice to procedural knowledge (Phye, Contemp Educ Psychol 16:87–94, 1991; Phye et al., Empirical methods for evaluating educational interventions, Academic Press/Elsevier, San Diego, 2005). Two studies involving ten and four adult ESL learners were conducted in a Midwest community college. Grammar teaching occurred within the context of history and geography of the USA. Students with low prior knowledge of passive voice grammar concepts, intermediate level of general vocabulary, and adequate basic knowledge of content (basic geography and history) benefited most from the program. Preliminary results are encouraging for the aforementioned integrative efforts.  相似文献

Although researchers have reported positive effects on teacher learning from observing published video, teachers’ own video, and their colleagues’ video, very few professional development programs have integrated all three types of video to improve teacher learning. In this study, we examined the affordances and challenges of the three types of video when they were used in a Problem-Based Learning professional development program, drawing upon multiple data sources from 26 K-12 science teachers. We present a case study to illustrate how one teacher might learn from each type of video, and conclude with recommendations for using video in professional development.  相似文献
