The pedagogical practices of mathematics education for young children in English and Korean pre-schools were compared through analyses of interviews with practitioners, observations of classroom activities and an examination of documents related to the planning and implementation of mathematics education. Practitioners in both countries used integrated activities to teach mathematics, although they used such activities more frequently in nurseries than in reception classes in England and more frequently in state settings than in independent settings in Korea. Furthermore, mathematics education was more structured, more likely to be led by an adult and less holistic in reception classes than in nurseries in England, whereas it was more structured and didactic in independent than in state settings in Korea. However, mathematics education in England was more systematic, used a more individualised approach and incorporated a variety of hands-on materials and rigorous outdoor activities, whereas it was more group-oriented and utilised limited materials and fewer outdoor activities in Korea. 相似文献

The purpose of this study was to describe the knowledge base of a group of science teachers in terms of their knowledge of the structure, function, and development of their disciplines, and their understanding of the nature of science. The study also aimed to relate the teachers' knowledge base to their level of education, years of teaching experience, and the class level(s) that they teach. Twenty inservice science teachers were selected to respond to a modified version of the Views on Science–Technology–Society (VOSTS) questionnaire to assess their understanding of the nature of science. The teachers then constructed concept maps and were interviewed. The concept maps were scored and the interviews analyzed to assess teachers' knowledge of the structure, function, and development of their disciplines. The teachers' knowledge base was found to be lacking in all respects. Teachers held several naive views about the nature of science and did not demonstrate adequate knowledge and understanding of the structure, function, and development of their disciplines. Moreover, the teachers' knowledge base did not relate to their years of teaching experience, the class level(s) that they teach, and their level of education. It was reasoned that teacher preparation programs are not helping teachers develop the knowledge base needed for teaching science. © 1997 John Wiley & Sons, Inc.

This research investigated the effect of reflective discussions following inquiry‐based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty‐eight grade six students from a Lebanese school participated in the study. The study used a pretest–posttest control‐group design and focused on collecting mainly qualitative data. During each laboratory session, students worked in groups of two. Later, experimental group students answered open‐ended questions about NOS then engaged in reflective discussions about NOS. Control group students answered open‐ended questions about the content of the laboratory activities then participated in discussions of results of these activities. Data sources included an open‐ended questionnaire used as pre‐ and posttest, answers to the open‐ended questions that experimental group students answered individually during every session, transcribed videotapes of the reflective discussions of the experimental group, and semi‐structured interviews. Results indicated that explicit and reflective discussions following inquiry‐based laboratory activities enhanced students' views of the target NOS aspects more than implicit inquiry‐based instruction. Moreover, implicit inquiry‐based instruction did not substantially enhance the students' target NOS views. This study also identified five major challenges that students faced in their attempts to change their NOS views. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 1229–1252, 2010 相似文献

Although a well‐corroborated scientific theory, the theory of evolution has continued to cause dilemmas for some individuals who have not easily been able to accommodate the concepts of this theory within their “cognitive culture.” The reason lies in the overlap of some ideas that the theory advocates with other social, epistemological, and religious beliefs. This study describes how 11 college biology students who completed a course on the theory of evolution perceive the relationship among their epistemological beliefs about science, their beliefs about religion, and their perception of nature and causality and their position regarding the theory of evolution. It also compares the different positions of the students to that of the course instructor. Questionnaires and semistructured interviews were used to collect data. Qualitative methods were used to analyze the data and identify the various positions of the students and course instructor. The students' positions ranged from complete acceptance to complete rejection of the theory of evolution. The results suggest that students' personal beliefs should not be dismissed or underestimated when teaching the theory of evolution. © 2008 Wiley Periodicals, Inc.

The academic "hurdle race": A case study 总被引：1，自引：0，他引：1
This study analyzes the career patterns of a cohort of faculty members in a large Israeli university and shows that women constitute a small minority in that university, and that their rank advancements are fewer, slower, and lower than men's. We examine three possible explaining mechanisms: (a) "Thresholds" - according to which after women cross a certain barrier, differential career development on the basis of gender disappears or is, at least, greatly reduced. (b) "Ceilings" - according to which women's advancement is curbed before they reach the highest rank. (c) "Hurdles" - according to which women, as compared to men, are confronted by more obtrusive barriers at each step of the academic career. We found that no threshold could be detected after which gender differences are reduced and that the ceiling effect may be a by-product of women's extended career paths. Rather, the analysis of the case study suggests that women's career trajectories are characterized by "hurdles", i.e., at each rank they stay longer and their advancement probability is lower than men's even when their publication rates are taken into account. 相似文献

The purposes of this study are as follows: (a) to investigate the relationship between high school students' learning approaches, prior knowledge and attitudes toward chemistry, and their performance on a misunderstandings test; and (b) to describe and analyze the differences between the responses of students with different learning approaches on the same test. Forty-nine suburban high school students enrolled in two sections of New York State Regents Chemistry classes participated in the study. The students' performance on a misunderstandings pretest and the students' learning approach both accounted for a statistically significant proportion of the variance on their performance on the misunderstandings posttest. Additionally, the results showed that the relatively meaningful learners performed significantly better than the relatively rote learners on the misunderstandings posttest. 相似文献
