This study focuses on elucidating and explaining reasons for the stability of and interrelationships between students’ conceptions about Light Propagation and Visibility of Objects using contextualized questions across 3 years of secondary schooling from Years 7 to 9. In a large-scale quantitative study involving 1,233 Korean students and 1,149 Singaporean students, data were analyzed from responses to the Light Propagation Diagnostic Instrument consisting of four pairs of items, each of which evaluated the same concept in two different problem situations. Findings show that only about 10–45 % of students could apply their conceptions of basic optics in contextualized problem situations giving rise to both stable and unstable alternative conceptions. Students’ understanding of Light Propagation concepts compared with Visibility of Objects concepts was more stable in different problem situations. The concepts of Light Propagation and Visibility of Objects were only moderately correlated. School grade was not a strong predictive variable, but students’ school achievement correlated strongly with their conceptual understanding in optics. The teaching and learning approach and education systems in the two countries may have had some influence on students’ conceptual understanding. 相似文献

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK. 相似文献

The use of technology in schools is now ubiquitous, but the effectiveness on the learning environment has mixed results. This paper describes the development and validation of an instrument to measure students’ attitudes toward and knowledge of technology with the aim of investigating any differences based on gender after a course where the science department made use of technology as an integral part of teaching biology. In this study, conducted in one school in the state of New York, in the United States of America, the Students’ Attitudes Toward and Knowledge of Technology Questionnaire was administered to nearly 700 high school science students. A principal component and principal factor analysis resulted in new scales from the validation of the instrument that demonstrated high reliabilities. There were statistically significant gender differences in all the scales of the questionnaire in favor of males. 相似文献

Research on the teaching profession in Russia shows that teachers continue to be among the lowest paid specialists. Despite this, recruitment is possible since teachers find the yearly schedule attractive, and this compensates somewhat for lower salaries. There is concern, though, about the conditions of their work and the inadequate amount of funding that is provided for essential supplies and infrastructure. 相似文献

The traditions of higher education in Russia dealing with elements of student government have been weakened in recent years, but recent research shows support among Russian students for greater involvement in activities related to their lives as students. 相似文献

The provision of access to professional education for handicapped students in Russia faces a number of problems. Research shows that special attention needs to be given to such issues as the practice of preferential enrollment for handicapped people, the main factors limiting access to a professional education, and the provision of an obstacle-free environment. 相似文献

This phenomenological study, based on ecological systems theory, examined the college student bereavement experience in a Christian university. Undergraduate students (N = 127) from a small Christian university provided answers to open‐ended questions about their experiences regarding college following a death loss. Results indicate that students are generally successful in adapting to bereavement and prefer an environment open to discussing death and asking difficult religious questions. Implications for counselors are provided. 相似文献

This article provides an overview of the characteristics of the flipped classroom, discusses the foundations of this innovative instructional model, and analyzes the possibility of adoption and application to corporate learning platforms. The article assesses whether the flipped classroom is simply a temporary trend in education and learning or has the potential to truly revolutionize instructional design and delivery in the realm of training and development. 相似文献

From all over the world there have been calls from governmental institutions to address a shortage of high quality teachers. As changing jobs generates new experiences, job mobility could be a way for teachers to adhere to the government’s call to develop themselves into the teaching force needed. The research question of this study was: How do the experience with mobility and the attitude towards mobility of Dutch secondary school teachers shape their intentions to be mobile? A secondary analysis was conducted on data collected among 1261 respondents. Attitudes towards mobility were found to be linked to past experience with mobility and there is a strong relationship between the attitude towards mobility and the intention to be mobile. The control variables age, experience in teaching, and type of employment seem to have an effect as well. Implications for the teacher shortage issue are discussed. 相似文献
