This study explored the relationships among preservice teachers' conceptions of teaching using mobile devices and the quality of technology integration in lesson plans. A total of 47 preservice teachers in Taiwan who had experienced designing their own lesson plans and teaching materials (ie, eBooks and applications) for teaching using mobile devices (ie, smart phones and tablet PCs) participated in this study. The results showed that four qualitatively different conceptions of teaching using mobile devices were identified, namely “technology support,” “knowledge transmission,” “learning facilitation,” and “supporting students to learn.” This study also found that the teachers who had more constructivist perceptions of teaching using mobile devices, such as facilitating students' understanding in a convenient way or supporting student learning in a more active way, appeared to attain better quality technology integration in their lesson plans than those teachers with traditional conceptions. 相似文献

Educational researchers have suggested that computer games have a profound influence on students’ motivation, knowledge construction,
and learning performance, but little empirical research has targeted preschoolers. Thus, the purpose of the present study
was to investigate the effects of implementing a computer game that integrates the prediction-observation-explanation (POE)
strategy (White and Gunstone in Probing understanding. Routledge, New York, 1992) on facilitating preschoolers’ acquisition of scientific concepts regarding light and shadow. The children’s alternative
conceptions were explored as well. Fifty participants were randomly assigned into either an experimental group that played
a computer game integrating the POE model or a control group that played a non-POE computer game. By assessing the students’
conceptual understanding through interviews, this study revealed that the students in the experimental group significantly
outperformed their counterparts in the concepts regarding “shadow formation in daylight” and “shadow orientation.” However,
children in both groups, after playing the games, still expressed some alternative conceptions such as “Shadows always appear
behind a person” and “Shadows should be on the same side as the sun.” 相似文献

The purpose of this study was to explore the effects of the context-aware ubiquitous learning (u-learning) approach versus traditional instruction on students' ability to answer questions that required different cognitive skills, using the framework of Bloom's taxonomy of educational objectives, including knowledge, comprehension, application, analysis, and synthesis. In this study, 230 third- and fourth-grade students in 8 classes were counterbalanced and assigned to the u-learning approach and traditional instruction for learning different topics in two separate plant-observing activities. The results showed that the students who learned with traditional instruction performed better than those who used the u-learning approach in terms of answering questions that required their cognitive abilities of knowledge, comprehension, application, analysis, and synthesis. Moreover, an in-depth analysis of the students' learning behaviors in the u-learning context revealed that most of their learning behaviors recorded in the u-learning system were not significantly related to their cognitive abilities. 相似文献

The major purpose of this study was to investigate the effects of STS (Science-Technology-Society) instruction on a group of Taiwanese female tenth graders' cognitive structure outcomes. This study further examined the role of student scientific epistemological beliefs on such effects. One hundred and one female tenth graders were assigned to either a STS-oriented instruction group or a traditional teaching group and then this study conducted a eight-month research treatment. Students' interview details, analysed through a 'flow map' method, indicated that STS group students performed better in terms of the extent, richness and connection of cognitive structure outcomes than did traditional group students. Further analyses suggested that STS instruction was especially beneficial to students having epistemological views more oriented to constructivist views of science, particularly in the beginning stage of STS instruction. This implies that learners' scientific epistemological beliefs may be an important factor mediating the implementation of STS-oriented instruction. 相似文献

In educational measurement, the construction of parallel test forms is often a combinatorial optimization problem that involves the time-consuming selection of items to construct tests having approximately the same test information functions (TIFs) and constraints. This article proposes a novel method, genetic algorithm (GA), to construct parallel test forms effectively. The sum of squared errors of the generated TIFs produced by GA were compared with those of the Swanson and Stocking method, and the Wang and Ackerman method. Experimental results show that tests constructed using GA yielded lower error, and an average improvement ratio above 90%. 相似文献

The purpose of this study was to explore the differences between science students' and teachers' perceptions of laboratory environments. More than 1000 junior high school students and their science teachers in Taiwan were surveyed. The students showed much more dissatisfaction with approaches to laboratory activities than their teachers. They preferred a much more student-cohesive, open-ended, integrated and rule-clear laboratory environment than their teachers expected or preferred. However, the teachers sampled showed higher preferences for better equipment and material environments for laboratory work than did their students. Data from follow-up interviews with participant teachers suggested that epistemological views about science might be one of the important factors causing differences in perceptions between students and teachers of laboratory learning environments. 相似文献

Due to the scarcity of cross-cultural comparative studies in exploring students' self-efficacy in science learning, this study attempted to develop a multi-dimensional science learning self-efficacy (SLSE) instrument to measure 316 Singaporean and 303 Taiwanese eighth graders' SLSE and further to examine the differences between the two student groups. Moreover, within-culture comparisons were made in terms of gender. The results showed that, first, the SLSE instrument was valid and reliable for measuring the Singaporean and Taiwanese students' SLSE. Second, through a two-way multivariate analysis of variance analysis (nationality by gender), the main result indicated that the SLSE held by the Singaporean eighth graders was significantly higher than that of their Taiwanese counterparts in all dimensions, including ‘conceptual understanding and higher-order cognitive skills’, ‘practical work (PW)’, ‘everyday application’, and ‘science communication’. In addition, the within-culture gender comparisons indicated that the male Singaporean students tended to possess higher SLSE than the female students did in all SLSE dimensions except for the ‘PW’ dimension. However, no gender differences were found in the Taiwanese sample. The findings unraveled in this study were interpreted from a socio-cultural perspective in terms of the curriculum differences, societal expectations of science education, and educational policies in Singapore and Taiwan. 相似文献
