Different interpretations of scientific inquiry exist between the two different communities of scientists and science teachers. Thus, in order to achieve a successful partnership between science teachers and scientists in establishing effective communities of practice, the framework for instructional practice in teacher professional development needs to be carefully designed. To respond to this challenge, we developed the Inquiry Resources Collection (IRC), which offers a wiki-based inquiry resource collection developed by scientists to support novice science teachers?? inquiry lesson design. The collaborative managing and sharing of knowledge in a professional development program via a wiki environment is the key to developing a practical resource for novice teachers teaching scientific inquiry. Based on our reflection of data gathered during 4?years of our project, we invoked the ideas of boundary objects and reflective apprenticeship between scientists and teachers to design the IRC. 相似文献

This study employs a cross-cultural perspective to examine how local audiences perceive and enjoy foreign dramas and how this psychological process differs depending on the cultural distance between the media and the viewing audience. Using a convenience sample of young Korean college students, this study, as predicted by cultural discount theory, shows that cultural distance decreases Korean audiences’ perceived identification with dramatic characters, which erodes their enjoyment of foreign dramas. Unlike cultural discount theory, however, cultural distance arouses Korean audiences’ perception of novelty, which heightens their enjoyment of foreign dramas. This study discusses the theoretical and practical implications of these findings, as well as their potential limitations. 相似文献

A microfabricated calorimeter (μ-calorimeter) with an enclosed reaction chamber is presented. The 3D micromachined reaction chamber is capable of analyzing liquid samples with volume of 200 nl. The thin film low-stress silicon nitride membrane is used to reduce thermal mass of the calorimeter and increase the sensitivity of system. The μ-calorimeter has been designed to perform DC and AC calorimetry, thermal wave analysis, and differential scanning calorimetry. The μ-calorimeter fabricated with an integrated heater and a temperature sensor on opposite sides of the reaction chamber allows to perform thermal diffusivity and specific heat measurements on liquid samples with same device. Measurement results for diffusivity and heat capacitance using time delay method and thermal wave analysis are presented. 相似文献

Comparisons of the effects of typical and atypical typeface on reading performance among readers of different linguistic backgrounds may yield new insights into the psychology of word recognition. A total of 143 adults (i.e., 50 Chinese, 55 Koreans, 38 native English speakers) participated in the study that involved two computer-based naming tests. The tests presented words with letters that varied in size and shape in Experiment 1 and words containing scrambled letters in Experiment 2. Results from Experiment 1 showed that the interference effect of size and shape on word naming accuracy and latency was robust for all readers. Likewise, results from Experiment 2 showed a broad interference effect of scrambled letters on word naming; however, scrambled letters appeared less disruptive to word naming among Chinese readers compared to their Korean and native English speaking counterparts. Taken together, Chinese speakers were less efficient in recognizing atypical words at the sublexical level, but more efficient at the lexical level. 相似文献

Growing evidence from recent curriculum documents and previous research suggests that reform-oriented science teaching practices promote students’ conceptual understanding, levels of achievement, and motivation to learn, especially when students are actively engaged in constructing their ideas through scientific inquiries. However, it is difficult to identify to what extent science teachers engage students in reform-oriented teaching practices (RTPs) in their science classrooms. In order to exactly diagnose the current status of science teachers’ implementation of the RTPs, a valid and reliable instrument tool is needed. The principles of validity and reliability are fundamental cornerstones in developing a robust measurement tool. As such, this study was motivated by the desire to point out the limitations of the existing statistical and psychometric analyses and to further examine the validation of the RTP survey instrument. This paper thus aims at calibrating the items of the RTPs for science teachers using the Rasch model. The survey instrument scale was adapted from the 2012 National Survey of Science and Mathematics Education (NSSME) data. A total of 3701 science teachers from 1403 schools from across the USA participated in the NSSME survey. After calibrating the RTP items and persons on the same scale, the RTP instrument well represented the population of US science teachers. Model-data fit determined by Infit and Outfit statistics was within an appropriate range (0.5–1.5), supporting the unidimensional structure of the RTPs. The ordered category thresholds and the probability of the thresholds showed that the five-point rating scale functioned well. The results of this study support the use of the RTP measure from the 2012 NSSME in assessing usage of RTPs. 相似文献

This study investigated kindergarten teachers’ decision-making process regarding the acceptance of computer technology. We incorporated the Technology Acceptance Model framework, in addition to computer self-efficacy, subjective norm, and personal innovativeness in education technology as external variables. The data were obtained from 160 kindergarten teachers, from public kindergartens in Daejeon, South Korea. According to the results, subjective norm had the strongest effect on computer acceptance. In addition, perceived usefulness and computer self-efficacy had a direct effect on computer technology acceptance. On the other hand, perceived ease of use and personal innovativeness in education technology had an indirect effect on computer technology acceptance. The measures accounted for approximately 32% of the variance of intentions to use computers in kindergartens. 相似文献

This paper developed a Democratic Classroom Survey to measure students’ perceived democratic environment of the classroom. Perceived democratic environment is one of the most important variables for understanding classroom activity and indeed any type of group activity, but actually measuring perceptions in an objective manner has been problematic. We developed the survey items from both a strong theoretical and a practical perspective, with the contention that Pleasing Authority/External Motivation, Performance Orientation, Cooperation/Collaboration, Integrated Activity, and Goals before Trust/Inter-subjective would be important factors for measuring individual students’ perceptions of the classroom along an authoritarian/democratic continuum. Factor analyses (Exploratory followed by Confirmatory analyses) confirmed the structure of the hypothesized subscales, and the good model fit indicated that the survey is valid. Also, correlation analyses with Classroom Community Scale showed good construct validity. Finally, reliability tests for each subscale and split-half reliability tests showed that the survey is a reliable tool to use in college classrooms. Implications and future directions are discussed. 相似文献

This study explores the factors that cause international graduate students to struggle and these students' ways of dealing with such problems in light of sociocultural theory, which views learning as a social and cultural act. The findings show that graduate classes function as communities of practices in which classmates and professors mutually engage with each other, share a repertoire and engage in joint enterprises. The practices were not always transparent to international students, which became a source of difficulty and often led them to feel excluded. Peripheral participation comprised a significant part of some students' learning process and identity formation, but it allowed them to participate in course-related activities as fully as they felt comfortable doing. This study suggests a need for more sensitive and dialogical efforts by educators in higher education to provide better learning environments for international learners. 相似文献
