  • This study explored changes of preservice biology teachers' pedagogical knowledge and science teaching efficacy belief after the science pedagogy course. Preservice biology teachers who did not take any science pedagogy courses had an opportunity to engage in discussions of educational theories and group activities of instructional design utilizing science instructional models as a first step to develop practical knowledge. These preservice teachers represented a statistically significant increase in their scores on pedagogical knowledge including theory, student development, planning, and implementation, but no statistical difference in their scores measuring science teaching efficacy belief. In addition, the correlation results indicated that the science teaching efficacy belief is related to implementation even though the magnitude is relatively moderate.

  • Workplace knowledge sharing is a complex process and there are a large number of studies in the area. In this article three theoretical approaches in library and information science are used to discuss knowledge sharing in the workplace. The approaches are information behavior, social capital, and information culture, and they bring important insights that need to be considered from a holistic management point of view when it comes to knowledge sharing. The individual's relation to different levels of context is important, meaning both in relation to work roles, work tasks, situations, organizational structures, and culture. The frameworks also shed light on where and how knowledge sharing activities are present in the organization. From a knowledge management point of view, it is important to acknowledge that when knowledge is valued, there is also an awareness of the knowledge sharing activities. Also, in addition to more traditional views of context, the frameworks bring forward different views on context, such as time and space as contextual factors.

  • During the last two decades, many researchers have attempted to understand pedagogical content knowledge (PCK). Now it is time to think about how to apply the theoretical aspects of PCK to practice. In an attempt to address this issue, it is indispensable to review the existing literature on teachers' knowledge bases and PCK. Therefore, the purposes of this paper are to look at how the concept of PCK has been developed and extended over the past two decades as well as to provide a shared understanding of PCK for the practical use of this concept in teacher education programs. The paper begins with a discussion of various models of teachers' knowledge as conceptualized by several renowned researchers, moves on to a review of existing research focusing on the knowledge of science teachers, then examines the literature on PCK as a critical part of teachers' professional knowledge, and finally concludes with an integrated operational definition of PCK that can be employed into designing teacher education programs.

  • The objective of this study is developing an instrument for investigating views of the respondents on nature of science(NOS) by using experienced scientific knowledge, atomic model. It consists of total six questions and 36 detail items, and each question is reflected the aspects of different NOS which are 'recognition on the model', 'tentativeness of scientific knowledge', 'subjectivity in science', 'use of inference and imagination', 'myths of the scientific method', and 'comparison between science and art'. Particularly, 'comparison between science and art' is addressed almost for the first time in this questionnaire. In the class environment almost not to teach nature of science linking with concrete scientific knowledge, to inquire how the students recognize nature of science, relating to experienced scientific knowledge through this questionnaire will give the data of scientific knowledge based recognition on the nature of science and an important implication for nature of science teaching with concrete scientific knowledge. Developing processes have gone through four steps. In first step, we chose aspects of NOS and developed questions and details. In second step, we tested the draft into fifteen science teachers and, reflecting their opinions, corrected the form and contents of questionnaires. In third step, we tested the questionnaire included writing section for expressing thoughts of the respondents into 55 students in science high school and checked index of coincidence between Likert and open-ended responses which shows 88.2% degree of consensus. Furthermore, to identify the feature of using concrete scientific knowledge we applied this and views on science and education questionnaires together into six university students. We performed final test to 68 university students and measured Cronbach's, and ultimately completed final questionnaire in last step.

  • The purpose of this study was to analyze the mediating effect of pedagogical content knowledge of science teaching on the relations among child care teachers' burnout, science teaching anxiety, and science teaching efficacy. For this study, questionnaires were distributed to 355 teachers working at child care centers in Jollanam-do. The analysis of data was conducted with SPSS WIN 18.0. The results of this study were as follows. First, child care teachers' burnout lowered their science teaching efficacy, and child care teachers' pedagogical content knowledge, as a mediating variable, reduced the negative effect of child care teachers' burnout on their science teaching efficacy. Second, child care teachers' science teaching anxiety lowered their science teaching efficacy, and child care teachers' pedagogical content knowledge, as a mediating variable, reduced the negative effect of child care teachers' science teaching anxiety as an independent variable on their science teaching efficacy. These findings imply there is a need to boost pedagogical content knowledge during in-service teacher education programs.

  • The purpose of this study was to present the basic data for the education of nutrition to female teachers by surveying the degree of nutritional knowledge, the attitute toward nutrition and eating habits of the female teachers, and analyzing the present dietary food. 1. The average score of their nutritional knowledge was 17.53 (the highest mark was 25) and the percentage of the right answers was 73.6. 2. The nutritional knowledge was related to their ages, and whether or not they majored in domestic science. Younger and domestic science majors scores of nutitional knowledge were shown to be higher. 3. They had dinner more regularly than breakfast or lunch and the score of nutritional knowledge was higher in proportion to the regularity of their breakfasts. As nutritional knowledge was reflected in their daily lives and bread was used as a substitute of their meals, the degree of their nutritional knowledge was higher. 4. For self evaluation of nutritional knowledge, the higher the score of their nutritional knowledge was, the more they thought they knew and those with high scores seemed to get information about nutrition through specialized books and cookbooks.

  • Science education has been in a state of crisis for some time. To understand the science teacher's role, it is helpful to reconsider an aspect as fundamental as the nature of science. Since teaching cannot be separated from learning and knowledge, their very close dynamic processes need to prescribe the role of the teacher and student simultaneously. However, traditional views are limited because they tend to emphasize some particular selected aspect of learning and teaching. This paper investigates the epistemology of Michael Polanyi (1891 1976), which is often considered to transcend the confrontation between objectivity and subjectivity of knowledge. Polanyi reconceptualized science knowledge as 'personal knowledge' based on his own experience as a scientist and a thinker. In this study, I discuss 1) the nature of science in light of Polanyi's epistemology, 2) what this says about the meaning of science learning and teaching, 3) the potential of these ideas for the role of the science teacher.

  • The goal of this study was to examine the PCK required for science teachers and PCK required for university teacher educators in terms of school science knowledge, science teaching and learning, and the role of science educators, which are the main axes of science education in future schools, and to explore the relationship between them. This study is a follow-up to a previous stage of research that explored the prospects for changes in schools in the future (2040-2050) in terms of school knowledge, educational methods, and teacher roles. Based on in-depth interviews, qualitative and semantic network analyses were conducted to derive and compare the characteristics of PCK and PCK. As for the main research results, science teacher PCK in future schools should include expertise in organizing science classes centered on convergence topics, expertise in digital platforms and ICT use, and expertise in building a network of learning communities and resources, as part of the expertise of human teachers differentiated from AI. Teacher educators' PCK includes expertise in the research and development of T-L methods using AI, expertise in the knowledge construction process and practice, and expertise in developing preservice teachers' research competencies. Discussed in the conclusion is the change in teacher PCK and teacher educator PCK with changes in science knowledge, such as convergence-type knowledge and cognition-value integrated knowledge; and the need to emphasize values, attitudes, and ethical judgments for the coexistence of humans and non-humans as school science knowledge in the post-humanism future society.
