Turkey’s Anadolu University is one of the world’s largest mega‐universities. It is engaged in strategic planning in response to changes in the expectations of the Turkish Higher Education Council and the community at large. In re‐examining its vision and strategic directions, Anadolu University needs to be informed on the knowledge, skills, and attitudes of its teaching staff, and the systems and support needed to assure their change readiness. This article examines the literature of organizational and educational change and its implications for the university. It reports on a study based on the relevant constructs from the literature and is designed to gauge the extent and nature of teaching staff knowledge, skills, practice, and research in educational and technological change, motivating and de‐motivating factors, change adopter types, and perceptions of the organizational climate for change. It considers the implications of these findings and draws conclusions about what would be needed to improve staff readiness for change.  相似文献

The purpose of this study was to investigate the differences among schools using student responses in the Trends in Mathematics and Science Study–1999 (TIMSS‐99) data. Schools were classified into two groups based on eighth grade students' overall achievement in science. Two different discriminant function analyses were performed to distinguish high‐ and low‐performing schools, based both on classroom practices and factor structures (student‐centered activities, teacher‐centered activities, attitudes toward technology use, socioeconomic status [SES], and doing well in science). The results indicate that there were significant differences between the two classifications of schools on ten variables regarding classroom practices and activities, and 29 variables regarding classroom practices, attitudes toward science, use of the computer and overhead projector (OHP), parental background characteristics, and need to do well in science. Contrary to general expectations, technology use (computer, OHP, etc.) was found to be negatively related to science achievement. Teachers should be trained on how to use technology in their classrooms. Turkey recently revised its curriculum to a student‐centered approach and this might increase students' ability to transfer knowledge into real life. Teachers and schools should pay more attention to SES effects. Teachers should also work toward building students' confidence in science. © 2007 Wiley Periodicals, Inc.

The present study examined whether or not different input delivery modes have an effect on listening comprehension of Turkish students learning English at the university level. It investigated the effect of one single mode, which is audio-only, and three dual input delivery modes, which were audio-video, audio-video with target language subtitles and audio with PowerPoint presentation, on listening comprehension. The data have been gathered through: a listening proficiency exam, a topic familiarity questionnaire, listening comprehension tests, think-aloud protocols and a semi-structured focus group interview. Analysis of data demonstrated that the students’ listening comprehension scores were significantly lower in audio-video with subtitles mode. In addition to this, the students stated that they experienced most confusion and anxiety in understanding through audio-video with subtitles. Moreover, the students mentioned that they were most successful in the audio with PowerPoint presentation mode. Results also indicated that the students were influenced by their pre-university listening class experiences, meaning that they were most accustomed to the audio-only mode, and therefore felt most relaxed when they listened only.  相似文献

Use of different teaching materials and curriculum for the same subjects is always a confounding factor in studies investigating teacher characteristics and student achievement. The purpose of this study is to understand the effects of different teacher qualities on student achievement in high schools with a standards-based curriculum delivered over a blended learning environment. Utilizing quantitative research approach, this study investigates the effects of teacher characteristics and teaching practices in a course offered through Cisco Networking Academy, which has a standards-oriented curriculum delivered online. Participants in the study were 226 teachers and 3299 students from Networking Academies located in the USA. The findings suggest that certain teacher characteristics such as teaching experience, degree, and primary teaching field do not have effects on student achievement.  相似文献

Background: The development of primary pre-service teachers’ chemistry motivation and attitudes toward chemistry were examined in order to develop their science literacy using case-based learning. Students’ ideas were emphasized, real-life situations were discussed, and students could share their ideas and knowledge with peers; as a result, students were active in the learning process.

Purpose: The purpose of the study was to investigate the effectiveness of using case-based learning instruction to increase pre-service primary teachers’ chemistry motivation and improve their attitudes toward chemistry as a school subject.

Sample: The subjects of this study consisted of 51 (20 female, 31 male) freshman primary pre-service teachers from an urban university in Turkey. The mean age of the primary pre-service teachers was 21.

Design and methods: One group pre-test and post-test design was used. A chemistry motivation questionnaire and chemistry attitude scale were used for data collection. For the data analysis, two-way repeated measures of ANOVA and repeated measures MANOVA were conducted.

Results: The results indicated that the mean of the attitude score after the treatment was significantly greater than the mean of the attitude before the treatment. The results also demonstrated that there is no significant difference between females and males. According to the results of the study, there is no significant difference between primary pre-service teachers’ chemistry motivation. However, some chemistry motivation constructs mean scores are greater after the treatment.

Conclusions: In sum, it could be stated that case-based learning is helpful for the development of students’ chemistry motivation and attitudes toward chemistry.  相似文献
