Exploring Elementary Pre-service Teachers’ Beliefs About Science Teaching and Learning as Revealed in Their Metaphor Writing     

Eulsun Seung  Soonhye Park  Ratna Narayan 《Journal of Science Education and Technology》2011,20(6):703-714

This study examined elementary preservice teachers’ beliefs about the role/image of a science teacher and science teaching and how these beliefs change during an elementary science methods course; this examination was conducted through an analysis of their metaphor writing. Data included personal metaphors and rationale papers for supporting them collected from 106 participants at the start and end of the semester. Data were analyzed using the constant comparative method and also quantified for statistical analysis. Results indicate that most participants came to the course with traditional views and developed more constructivist views during the course. However, they tended to keep their traditional views and added new constructivist perspectives into their original belief systems. This study suggests that metaphor writing can be used as both a reflection tool for preservice teachers to clarify and refine their beliefs about science teaching and learning and a diagnostic assessment tool for teacher educators to understand their students for tailoring a methods course accordingly.  相似文献   

Foundational Concepts for Conducting Program Evaluations     

Seung Youn Chyung 《Performance Improvement Quarterly》2015,27(4):77-96

Evaluation is one of the critical steps in the process of performance improvement. Evaluation feeds evidence‐based information back to the next cycle of performance improvement. However, organizations often neglect to conduct comprehensive evaluations on their programs due to environmental barriers or the lack of practitioners’ evaluation expertise. This article presents some of the foundational evaluation‐related concepts and procedures that would help human performance improvement practitioners when conducting comprehensive systematic and systemic evaluations of the interventions implemented in organizations: (a) evaluation versus research, (b) front‐end evaluation versus back‐end evaluation, (c) definition of program evaluation, (d) types of program stakeholders, (e) development of program logic models, (f) formative evaluation versus summative evaluation, (g) merit versus worth, and (h) development of evaluation dimensions. Such foundational knowledge is just one of the first steps to prevent evaluations from being neglected or mistaken with simple measurements through administering instruments such as smiley sheets.  相似文献   

Foot and ankle joint movements of dancers and non-dancers: a comparative study     

Ho-Jung Cho  Soyeon Kim  Joon-Yong Jung 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(6):587-594

Ballerinas use their ankle joints more extremely and sustain injuries on the ankle joint more frequently than non-dancers. Therefore, the ankle movement of dancers is important and should be studied to prevent injuries. Measuring ankle joint range of motion (ROM) using radiographs could demonstrate the contribution to motion of each joint. The aim of this study was to analyse and compare ankle joint movements and the ratio of each joint’s contribution during movement between dancers and non-dancers, using radiographic images. Dancers have lower dorsiflexion (26.7 ± 6.2°), higher plantarflexion (74.3 ± 7.1°) and higher total (101.1 ± 10.8°) ROMs than non-dancers (33.9 ± 7.0°, 57.2 ± 6.8° and 91.1 ± 9.3°, respectively) (p < 0.05). Although the ROMs were different between the two groups, the ratios of each joint movement were similar between these two groups, in all movements. Regarding total movement, the movement ratio of the talocrural joint was almost 70% and other joints accounted for almost 30% of the movement role in both dancers and non-dancers. Therefore, the differences in ROM between dancers and non-dancers were not a result of a specific joint movement but of all the relevant joints’ collaborative movement.  相似文献   

Learning by self-explaining causal diagrams in high-school biology     

Young Hoan Cho  David H. Jonassen 《Asia Pacific Education Review》2012,13(1):171-184

Understanding scientific phenomena requires comprehension and application of the underlying causal relationships that describe those phenomena (Carey 2002). The current study examined the roles of self-explanation and meta-level feedback for understanding causal relationships described in a causal diagram. In this study, 63 Korean high-school students were randomly assigned to one of three conditions: instructional explanation, self-explanation, and meta-level feedback. Results showed that self-explaining a causal diagram was as effective as studying instructional explanations. Furthermore, the effectiveness of self-explaining a causal diagram was enhanced by meta-level feedback that prompted students to reflect on their own explanations by comparing them with instructional explanations. We identified three main difficulties that high-school students experienced when explaining a causal diagram to themselves: one-sided explanation, erroneous explanation, and the lack of inference. Implications of the study were discussed in regard to the improvement of self-explanation and the design of causal diagrams in science education.  相似文献

Korean 4‐ to 11‐year‐old student conceptions of heat and temperature     

Seoung‐Hey Paik  Boo‐Kyung Cho  Young‐Mi Go 《科学教学研究杂志》2007,44(2):284-302

The aim of the present study is to shed light on the conceptions that young students have of heat and temperature, concepts that are both important in school science curricula and closely related to daily life. The subjects of the study were students from a rural district in South Korea and they ranged in age from 4 to 11 years. Interviews were conducted with each student on the basis of questions on temperature, thermal insulation, and heat equilibrium. After calculating the frequency and percentage of student responses and analyzing the rationale for their answers, it was found that younger students tended to view temperature as “size” or a “summation of numbers.” This tendency gradually diminished in older students. Most students had alternative conceptions of thermal insulation regardless of age; however, reasoning differed according to age. Younger students displayed a greater tendency to view insulation as a material property, whereas older students showed a greater tendency toward rational heat and temperature conceptions. Most students did not have clear concepts of heat equilibrium regardless of age, but possessed numerous alternative conceptions. © 2007 Wiley Periodicals, Inc.

Rasch Validation of a Measure of Reform-Oriented Science Teaching Practices     

Hye Sun?YouEmail author 《Journal of Science Teacher Education》2016,27(4):373-392

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   

The acceptance of computer technology by teachers in early childhood education     

Hye In Jeong  Yeolib Kim 《Interactive Learning Environments》2017,25(4):496-512

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
