Four sessions of two professional development seminars were offered to members of an organization. The seminars were voluntary, free of charge, and participants did not receive credit for their attendance. Participation rates and exit survey ratings for the four sessions varied. After the seminars, an analysis using the community of inquiry framework was conducted to better understand what occurred in the dialogue of the seminars to understand whether patterns of facilitator actions related to the amount of participation and exit survey ratings. The design of the seminars, the activities in the seminars, and the importance of the facilitator to plan and then help foster interaction in voluntary professional development seminars are discussed relative to the community of inquiry model. 相似文献

Web searching is a timely topic which importance is recognized by researchers, educators and instructional designers. This paper aims to guide these practitioners in developing instructional materials for learning to search the Web. It does so by articulating ten design principles that attend to the content and presentation of Web searching instruction. These principles convey a mixture of insights gleaned from instructional theory, empirical research, and many hours of classroom experience. Together, these design recommendations elucidate the key characteristics of effective Web searching instruction, explaining not only what the instructional materials look like, but also why they look the way they do. 相似文献

This study examined the efficacy of minimalist instruction to develop self-regulatory skills involved in Web searching. Two versions of minimalist self-regulatory skill instruction were compared to a control group that was merely taught procedural skills to operate the search engine. Acquired skills were tested on Web search tasks and search tasks in an online library catalogue. Self-regulatory skill instruction was found to increase practice time by 25%. However, it did not enhance search performance on the test tasks. Explanations are advanced for these findings and topics for further research are identified. 相似文献

This study investigated how professional development featuring evidence‐based customization of technology‐enhanced curriculum projects can improve inquiry science teaching and student knowledge integration in earth science. Participants included three middle school sixth‐grade teachers and their classes of students (N = 787) for three consecutive years. Teachers used evidence from their student work to revise the curriculum projects and rethink their teaching strategies. Data were collected through teacher interviews, written reflections, classroom observations, curriculum artifacts, and student assessments. Results suggest that the detailed information about the learning activities of students provided by the assessments embedded in the online curriculum motivated curricular and pedagogical customizations that resulted in both teacher and student learning. Customizations initiated by teachers included revisions of embedded questions, additions of hands‐on investigations, and modifications of teaching strategies. Student performance improved across the three cohorts of students with each year of instructional customization. Coupling evidence from student work with revisions of curriculum and instruction has promise for strengthening professional development and improving science learning. © 2010 Wiley Periodicals, Inc.

This study assessed the influence of a 3‐year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS‐B and associated interviews the researchers tracked the changes in NOS views of teacher participants throughout the professional development program. The teachers participated in explicit–reflective activities, embedded in a program that emphasized scientific inquiry and inquiry‐based instruction, to help them improve their own elementary students' views of NOS. Elementary students were interviewed using the VNOS‐D to track changes in their NOS views, using classroom observations to note teacher influences on student ideas. Analysis of the VNOS‐B and VNOS‐D showed that teachers and most grades of elementary students showed positive changes in their views of NOS. The teachers also improved in their science pedagogy, as evidenced by analysis of their teaching. Implications for teacher professional development programs are made. © 2006 Wiley Periodicals, Inc.

This article focuses on the potential of free tools, particularly inquiry tools for influencing participation in twenty-first-century learning in science, as well as influencing the development of communities around tools. Two examples are presented: one on the development of an open source tool for structured inquiry learning that can bridge the formal/informal spaces for inquiry learning. This is contrasted with an example of the use of free tools and community development for observation of scientific phenomena supported by open educational resources (OER) with a citizen science perspective. The article provides an assessment of how the availability of the resources has a potential for shaping the communities using OER for science learning and a discussion of the means of supporting inquiry. 相似文献

Many students have a deep interest in astronomy, but a limited opportunity to use telescopes to explore the heavens. The MicroObservatory Network of automated telescopes is designed to provide access to classroom teachers who wish their students to conduct projects over the World Wide Web. The intuitive interface makes it easy for even 10-year-olds to take pictures. Telescopes can be remotely pointed and focused: filters, field of view, and exposure times can be changed easily. Images are archived at the website, along with sample challenges and a user bulletin board, all of which encourage collaboration among schools. Wide geographic separation of instruments provides access to distant night skies during local daytime. Since first light in 1995, we have learned much about remote troubleshooting, designing for unattended use, and for acquiring the kinds of images that students desire. This network can be scaled up from its present capability of 240,000 images each year to provide telescope access for all US students with an interest in astronomy.

1980年以来,物理教学中始终关注培养学生的能力,在教学中也尝试运用问题教学法、发现学习法和探究式教学法,这些方法中都包含有探究的思想．新一轮课程改革所提倡的探究学习方式是这一思想的继承和超越． 相似文献

Online courses play an increasing role in professional development of environmental educators, yet little information is available on the interactive processes involved in online learning. We examined the relationship of three types of interactions in an urban environmental education online course – participant–participant, participant–instructor, and participant–content – to four course outcomes: participants’ motivation to learn, intent to adapt ideas and information learned through the course in their practice, actual adaptation of ideas in their practice, and development of professional networks. Content analysis was used to characterize participants’ and instructors’ weekly online posts and comments, and generalized estimation equation modeling was used to explore the relationships between interactions and outcomes. The results showed that participant–content interaction had significant positive relationships with participants’ motivation to learn, intent to adapt ideas, and adaptation of ideas. Participant–participant interaction had significant positive relationships with participants’ motivation to learn, and development of professional networks with each other. Finally, participant–instructor interaction had a significant positive relationship with participants’ development of professional networks. The results of this study can be used to improve professional development online courses for environmental educators. 相似文献
