The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed
chemistry instruction on eleventh grade students’ epistemological beliefs and their attitudes toward chemistry as a school
subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school
instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based
learning and the control group received traditional instruction. At the experimental group, life cases were presented with
small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant
difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry
as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students’
epistemological beliefs and attitudes toward chemistry. 相似文献

In reviewing literature on culturally and linguistically diverse (CLD) parental inclusion and disproportionality, Cam Cobb, assistant professor at the University of Windsor, Ontario, illustrates how CLD giftedness – and especially CLD giftedness in Canadian settings – represents an area in need of further research. In part, this article begins to address that need. Drawing from a larger critical qualitative inquiry, he details the stories of two CLD Canadian mothers as they sought to become involved in gifted identification and decision‐making processes. Knowledge and language arose in the data as two core themes of robust parental inclusion. These core themes, along with associated recommendations for policy, practice and research, are outlined in a discussion of the findings. While this article focuses on the gifted domain of special education in Ontario, the findings have wider implications for robust CLD parental inclusion in special education in general. 相似文献

The purpose of this study was to translate the original version of the Epistemic Belief Inventory developed by Schraw, Bendixen, and Dunkle (2002) for pre-service teachers in a Turkish context and validate its construct. Studies on the epistemological beliefs of Turkish students have been heretofore limited in number and have been largely conducted using adapted versions of the Schommer (1990) instrument. First, the original questionnaire was translated from English to Turkish and then was scrutinized by experts in language, content, measurement, and evaluation. Then, the revised questionnaire was administered to 166 Turkish pre-service teachers. The results of exploratory factor analyses suggested 3 epistemological belief dimensions – quick learning, innate ability, and certain knowledge. The results of the study further revealed support for multidimensional theories of epistemological beliefs among pre-service teachers. In order to verify the results of the present study, further examination of pre-service teachers' epistemological belief systems is necessary. 相似文献

A modification of the nonlinear curve-fitting procedure proposed by Wetherington and Lucas (1980) was used to assess how well Herrnstein’s (1970) equation for the rates of responding during concurrent schedules described performance. The equation fitted some results very well, accounting for 80% or more of the variance in the data in studies that used moderate-duration changeover delays and provided the same positive reinforcers, operanda, and simple schedules in the two components. The equation fitted the data poorly in other studies. The k parameter changed with several variables; it was not as constant as Herrnstein (1974) suggested. R0 did not fit Herrnstein’s interpretation as reinforcement from unprogrammed sources. Forty percent of all values of R0 were negative, and another 23% were unreasonably large (greater than 50 reinforcers/h). The data suggest that Herrnstein’s equation is not a general theory of concurrent-schedule responding, and that Herrnstein’s interpretation of k and R0 should be modified. 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

The purpose of this study was to examine preservice teachers' perceptions of the support their teacher education programs provide for developing their technological pedagogical content knowledge (TPACK). The research was conducted with 215 preservice teachers in the last year of teacher education programs and teaching certificate programs in three universities in Turkey. Data sources were the synthesis of qualitative evidence (SQD) scale that was validated in the Turkish context as part of this study and the TPACK-practical scale. The strategies investigated in the SQD-model included: using teacher educators as role models; reflecting on the role of technology in education; learning how to use technology by design; collaboration with peers; scaffolding authentic technology experiences; and providing continuous feedback. The linear regression analysis revealed a positive relation between teacher education strategies and preservice teachers' TPACK. Reflection and teacher educators' as role models were the most frequently used teacher education strategies in teacher education programs included in this study. Results provided recommendations for further research on the connection between the teacher education strategies and the development of preservice teachers' TPACK in teacher education programs. 相似文献

The French government adopted a policy of raising the education level of young people following a vocational track in response to the growing problems this group was experiencing in entering the labour market. To achieve these ends, a new diploma was created, the 'bac professionnel'. In the French education system, the baccalauréat has traditionally operated as both a level of education and a social barrier. The baccalauréat thus offers its holders both the chance to follow higher-level studies and also access to middle and upper-middle class jobs. In creating a 'bac professionnel', the French government destroyed the barrier between the middle and the working classes and opened the university gates to young people who until then had been denied access. The effects of the policy have meant the 'massification' of higher education, but also a marked loss of clarity in the way upper levels of education and training are organised, and, at company level, the phenomenon of overqualified people in subordinate positions. 相似文献

Three pigeons pecked keys for food reinforcers delivered by multiple variable interval variable interval schedules in the first part of each session (baseline) and by multiple variable interval extinction schedules in the second part of each session (contrast). The variable interval schedules delivered reinforcers after an average of 4 min or 30 sec in different conditions. The duration of a time-out between the components varied in five steps from 5 to 120 sec. Positive contrast occurred for all time-out durations in both experiments. That is, the rate of responding emitted during the constant, variable interval component was greater during the contrast than during the baseline schedules. The size of contrast did not change systematically with changes in timeout duration. These results violate most theories of contrast. They are compatible with the idea that animals integrate reinforcers over intervals longer than 2 min. 相似文献

Drawing from a critical qualitative inquiry, this case study tells the story of Hana, a Korean‐Canadian mother, and identifies barriers that can be encountered in seeking to interact with school professionals in the special education milieu. The case study presents a conceptual model, called the three‐legged stool of parental inclusion, which is designed to enhance the way in which parental inclusion is understood and fostered in special education. It is suggested that Hana needed to utilise this model, of knowledge awareness, gathering, and use, in order to take part in her daughter's education in a more meaningful way. This article, by Cam Cobb of the University of Windsor, Canada, adds to the international literature related to cultural and linguistic diversity by sharing a Canadian parent's experience of special education decision‐making from this perspective. 相似文献
