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.

A Case Study Exploring the Identity of an In-Service Elementary Science Teacher: a Language Teacher First     

Marco-Bujosa  Lisa  Levy  Abigail Jurist  McNeill  Katherine 《Research in Science Education》2020,50(1):79-98

Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher’s understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee’s (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher’s identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.

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

Situated Simulation-Based Learning Environment to Improve Proportional Reasoning in Nursing Students     

Ilana Dubovi  Sharona T. Levy  Efrat Dagan 《International Journal of Science and Mathematics Education》2018,16(8):1521-1539

Proportional reasoning is the basis for most medication calculation processes and is fundamental for high-quality care and patient safety. We designed a simulated Medication Mathematics (siMMath) environment to support proportional reasoning in transitioning via concreteness fading between two mediators. The first mediator is simulated nursing tools of medication preparation. The second is a ratio-table setup which is used as a goal representation, which enables one to spatially hold in place different quantities in their relative proportion. We conducted a two-part study with nursing students. Part 1 was a quasi-experimental pretest–intervention–posttest design assessing the effectiveness of learning, by evaluating four categories of medical calculation questionnaire items (solid medications, unit conversion, concentrations, infusion rates). We used the Noelting proportional reasoning test to evaluate the generalizability and abstraction of proportional reasoning. Part 1 included an experimental group (n = 96) learning with siMMath, and a comparison group (n = 73) learning with an equation-based lecture approach. Part 2 employed a case study design to characterize the learning process. The experimental group’s learning gains were significantly higher than the comparison group’s for the two most challenging categories of the medication calculation problems questionnaire, namely concentrations and infusion rates. Furthermore, the experimental group’s learning gains were significantly higher than the comparison group’s for formal operational reasoning on the Noelting test. Students who used a ratio-table setup scored significantly higher on the Noelting posttest questionnaire. Nursing students who learned with the siMMath environment overcame difficulties in proportional reasoning to the highest levels and extended this understanding to other contexts.  相似文献
