Promoting environmentally sustainable attitudes and behaviour through free‐choice learning experiences: what is the state of the game?     

Roy Ballantyne  Jan Packer 《Environmental Education Research》2005,11(3):281-295

Environmental education, both in and outside of the classroom, aims to facilitate adoption of sustainable practice by both school students and the general public. This paper explores the role of free‐choice learning experiences in this regard. An overview of theoretical approaches underpinning free‐choice learning research is provided, examples are presented of the ways in which informal educational settings can promote environmentally sustainable attitudes and behaviour, and the factors contributing to the effectiveness of these endeavours are discussed. By reviewing research evidence in relation to these issues, the paper identifies the current ‘state of the game’ and areas where new research is needed.  相似文献   

The effects of different feedback strategies using computer-administered multiple-choice questions as instruction     

Roy B. Clariana  Steven M. Ross  Gary R. Morrison 《Educational technology research and development : ETR & D》1991,39(2):5-17

This study investigated the effects of using different forms of computer-based feedback on high school students' learning of science material. The basic design consisted of two conditions of instructional support (text and questions vs. questions only), two testings (immediate vs. retention), five levels of similarity between lesson and posttest questions, and five feedback conditions: knowledge of correct response (KCR), delayed KCR, answer until correct (AUC), questions only (no feedback), and no questions. Results showed significant benefits for feedback over no feedback, with AUC becoming more advantageous and delayed feedback less so as lesson-posttest question similarity decreased. Also, with decreased question similarity and the availability of supporting text, overall feedback effects tended to decrease. The results are discussed in terms of the information processing effects of the different feedback forms, a factor that CBI designers often fail to exploit in planning feedback conditions.This article is based on a doctoral dissertation submitted to the faculty of Memphis State University by the first author.

Discriminating between Competent and Not Yet Competent Beginning Teachers: an analysis of principals’ reports     

Roy Ballantyne  Robert Thompson  Peter Taylor 《Asia-Pacific Journal of Teacher Education》1996,24(3):293-307

Principals’ written assessments of 50 high school teachers whom they judged competent for full registration and 32 whom they judged not yet competent and in need of an extended period of provisional registration were analysed in terms of the characteristics used to describe and determine beginning teacher competence. It was found that principals consistently refer to a narrow range of characteristics when describing competent beginning teachers and focus on an even narrower range in deciding whether or not full registration should be granted. Characteristics that describe approaches to teaching are used most often in this regard. While the majority of beginning teachers possess an adequate knowledge base in their subject area, success in the first year of school experience hinges on the ability to communicate such knowledge and concepts to students. The need for further refinement of the appraisal process, including professional development programmes for principals, is highlighted.  相似文献

MicroObservatory Net: A Network of Automated Remote Telescopes Dedicated to Educational Use     

Philip M. Sadler  Roy R. Gould  P. Steven Leiker  Paul R. A. Antonucci  Robert Kimberk  Freeman S. Deutsch  Beth Hoffman  Mary Dussault  Adam Contos  Kenneth Brecher  Linda French 《Journal of Science Education and Technology》2001,10(1):39-55

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.

Teaching Basic Science and Clinical Medicine at a distance: An Evaluation of Satellite Communication     

Charles W. Dohner  Elisabeth Zinser  Tom Cullen  M. Roy Schwarz 《Distance Education》1985,6(1):4-33

The evaluation plan arid preliminary results are reported for the ATS‐6 Satellite interactive telecommunication program for teaching at sites remote from an established medical school. The technical aspects of the system were seen as quite adequate and did not appear to substantially inhibit interaction. In the Fairbanks broadcasts analyzed, the average number of interactions ranged from 1.49 to 2.60 per minute. Ninety percent of the interaction flowed across the Satellite during Omak transmissions. Participants tended to initiate communication when they were on camera rather than when viewing their counterparts. Omak participants directed a higher percentage of the communication in student/resident programs (70%) than in faculty continuing education programs (59%). Interaction analysis indicated the categories of giving opinion, information, and suggestion were most frequent. Asking for opinion and suggestion occurred infrequently. The most frequent emotional expression was offering solidarity (e.g., reassurance), while there were exceedingly few expressions of disagreement, tension and antagonism. User acceptance of the system was determined to be very high. Participants with frequent exposure to the Satellite modality tended to have positive reaction. A significant difference in knowledge gain is reported in one of two basic science areas taught via Satellite as compared to regular instruction.  相似文献

The National Science Foundation-funded Center for Innovative Learning Technologies (CILT) is designed to be a national resource for stimulating research and development of technology-enabled solutions to critical problems in K-14 science, math, engineering and technology learning. The Center, launched at the end of 1997, is organized around four themes identified as areas where research is likely to result in major gains in teaching and learning, and sponsors research across disciplines and institutions in its four theme areas. CILT brings together experts in the fields of cognitive science, educational technologies, computer science, subject matter learning, and engineering. It engages business through an Industry Alliance Program and is also training postdoctoral students. CILT's founding organizations are SRI International's Center for Technology in Learning, University of California at Berkeley (School of Education and Department of Computer Science), Vanderbilt University's Learning Technology Center, and the Concord Consortium. Through its programs, CILT seeks to reach beyond these organizations to create a web of organizations, individuals, industries, schools, foundations, government agencies, and labs, that is devoted to the production, sharing and use of new knowledge about how learning technologies can dramatically improve the processes and outcomes of learning and teaching. This paper describes the rationale and operations of the Center, and first-year progress in defining a set of CILT partnership projects with many other institutions that came out of our national theme-team workshops. Roy Pea, of SRI International, is Director of CILT. Marcia Linn (U. California, Berkeley), John Bransford (Vanderbilt University), Barbara Means (SRI International), and Robert Tinker (Concord Consortium), serve as CILT's coprincipal investigators. Sherry Hsi (Ubiquitous Computing) and Sean Brophy (Technology and Assessment Models) are among the first group of CILT Postdoctoral Fellows. Jeremy Roschelle (SRI International) and Nancy Songer (University of Michigan) are CILT theme-team leaders. Roy Pea and Marcia Linn would like to thank the Spencer Foundation for support during their year at the Center for Advanced Study in the Behavioral Sciences, Stanford University, in which they developed the CILT concept with the other authors. CILT is funded by National Science Foundation grant #CDA-9720384. Pea and Linn would also like to acknowledge contributions to this article by the many authors of CILT partnership project proposals, and by theme-team leaders. The authors thankfully acknowledge Donna Baranski-Walker for her many contributions to developing the CILT Industrial Alliance Program while serving as its Director in 1998.  相似文献
