The purpose of this study was to analyze the stresses of teachers for elementary science class. To do these, the Science Teacher Stress Inventory has been developed the Science Teacher Stress Inventory, which consisted of 45 stress factors with subcategories such as student characteristics, teacher characteristics, expertise of science education, school environment, and administrative procedures. 120 teachers for elementary science class have participated in this questionnaire survey. The results of this study are as follow: First, stress from teacher characteristics is perceived as having more stress factors than five stress factors (student characteristics, teacher characteristics, expertise of science education, school environment, and administrative procedures). but all of the five stress factors was under normal. The detail question of stress such as 'Having to guide educational guidance and course in life education', 'Having to cope with the demand of new curricula', 'Pace of the school day is too fast', 'No time to attend training of the experiment (preliminary experiment)', 'Not enough time to complete lesson preparation and marking', 'Having to cope with non-teaching delegated duties', 'Fear of getting injured as a result of lab accidents' are perceived as having a lot of stresses. Second, there were not statistically significant differences in their personal variables such as gender, the course of high school. but there were statistically significant differences in their personal variables such as whether elementary subject exclusive science teacher, career in education experience, teaching grade. Third, coping ways of stresses are active support for better science teaching conditions, training of the experiment for expertise of science education, developing a workbook for science class.

An inquiry approach in teaching science has been advocated by many science educators for the past few decades, and most elementary and secondary science curricula have incorporated it in varying degrees. It has been proven in recent studies, however, that there exists considerable discrepancy between the expectation of outcomes of the inquiry approach and the actuality. This in part implies that there is a somewhat urgent need for the systematic evaluation of the approach in teaching science. The purpose of this study is to develop a comprehensive instrument for evaluating inquiry teaching approaches embedded in science curricular materials. To develop a more valid and reliable instrument a set of empirical data was used in the developmental procedure, and most of the previous studies regarding inquiry teaching method and inquiry evaluation were consulted. The inquiry evaluation method developed in this study, called the Scientific Inquiry Evaluation Inventory (SIEI), is composed of three parts: (1) analyzing and coding each science process task of inquiry activity; (2) evaluating each inquiry activity as a whole; and (3) evaluating each science laboratory curriculum as a whole. The first part of the instrument consists of twenty science process categories and thirty subcategories grouped into four sections: (1) gathering and organizing data; (2) interpreting and analyzing data; (3) synthesizing results and evaluation; and (4) hypothesizing and designing an experiment. The science process categories are arranged according to the level of difficulty, psychological level of thinking, degree of creativity demand, and the model of the process of scientific inquiry, which is also developed in the study. The second part of the instrument contains four evaluation scales of inquiry activity: (1) competition/cooperation scale; (2) discussion scale; (3) openness scale; and (4) inquiry scope scale. And the last part consists of three methods for evaluating a science laboratory curriculum as a whole: (1) inquiry pyramid; (2) inquiry index; and (3) difficulty index. The instrument is designed to be used by teachers, science curriculum developers and science education evaluators for the purpose of diagnosing the nature and appropriateness of scientific inquiry introduced in secondary science curricular materials, especailly in laboratory work and field work.

This study is to develop teaching aids and materials for geological fieldwork and to maximize their effects in educating high school students in Korea. The site of geological fieldwork, Kyokpo Chaeseokgang area, is located in Byunsan national park in Jeonbuk Province. The sedimentary succession of Chaeseokgang developed in the era of Cretaceous shows large-scale and distinct sedimentary structures on sea cliffs. In this study, teaching aids and materials of earth science for secondary-level students were developed based on the sedimentary structures of Chaeseokgang. A 5-step teaching model of earth science fieldwork was applied to a group of 13 students, who had been involved in clubs related to earth science in a science high school, using teaching aids and materials developed in this study. The teaching aids and fieldwork-related materials were also presented to a group of 37 students, who did not take fieldwork or fieldwork-related classes during the period of the study. The results of this study showed that the use of fieldwork-related aids and materials was effective in helping the students in both groups improve their self-directed teaming and practical understanding of earth science.

This study investigated the components of science teacher professionalism, the meaning of PCK (Pedagogical Content Knowledge), examples of science PCK, and complementary measures that should be taken to improve teacher professionalism. Six science teachers recommended by their colleagues explained that the science teacher's professionalism (or professional knowledge) consists of science content knowledge, knowledge about teaching, knowledge about learners, and improvement efforts. Science teachers' definition of PCK, which is the professional knowledge that members of the wider society expect teachers to possess, is the teacher's materialized knowledge that aims at students' understanding and PCK is the accumulated know-how of teachers as they strive to make their teaching comprehensible by students. Science teachers also contended that teachers as professionals need to complement an accountability system, acknowledgement of continuous self-developmental efforts, collegiality, and securing validity in the teacher employment test. The teachers argued that the societal recognition of teaching professionalism is essential for a high quality teaching. Suggestions for how to improve science teaching professionalism are also discussed.

The purpose of this study was to examine the types and characteristics of the knowledge constructed by pre-service secondary science teachers. Data included 26 student-teachers' narratives regarding their experiences in teaching high school students who were enrolled in extra-curricular science classes. It was revealed that the pre-service teachers awoke to the importance of subject matter knowledge, and learned it themselves in the situation of their own teaching. Especially their concern about science content knowledge was strongly associated with the matter of didactic transposition of the knowledge. The result also showed that the pre-service teachers constructed knowledge about the relationship with students as well as pedagogical knowledge to help students learn, and that they newly realized the nature of science in the context of teaching science. In addition, the teaching experiences allowed for the student-teachers to develop knowledge of oneself as a teacher and knowledge about science education in schools. It was believed that the knowledge constructed personally by the pre-service teachers from their teaching experiences could be a platform for the development of teacher expertise. Implications of the present study for science teacher education and relevant research were discussed.

The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."

In order to teach the nature of science which is one of the goals of science education, the aesthetic model of science was developed into a two-dimensional model through theoretical reviews on the aesthetic aspect of science. We represented 10 kinds of scientific experiments that scientists thought are beautiful in the aesthetic space of science. This paper tried to represent the greatest and famous scientific experiments in the history of science into the aesthetic space of science to find the suitability or usefulness of that model. At the same time, we were able to develop measuring tools as the Likert-scale with pictures of scientific experiments. Through this, we propose various teaching approaches on the nature of science (NOS) based on the aesthetic model of science and the potential for utilization in measuring the effects of the ways of teaching NOS.

This study evaluated the effect of diabetic group teaching programs in one university hospital in Seoul to predict when re-education would be needed. This study examined the patients’ knowledge at four points (before, directly after, three months and six months after the teaching program) and self-care performance related to diabetes twice (three months and six months after the teaching program). The subjects of the study were 24 admitted diabetic patients who participated in four-day teaching programs. Data were gathered from January to October, 1992 by means of an instrument developed from two diabetic knowledge tests which were equivalent in item differentiation and item discrimination coefficients. Collected data were analyzed by paired t-test, Pearson correlation, t and F tests. The results of study were as follows. 1. The analysis of the effect of the diabetic group teaching program and the duration of the effect of teaching. 1) The first hypothesis, that the diabetes knowledge score directly after the teaching program would be higher than before, was rejected (t=-1.40 ; p=.172). 2) The second hypothesis, that the diabetes knowledge score directly after teaching would be higher than three months later, was rejected(t= -4.27 ; p=.000). 3) The third hypothesis, that the diabetes knowledge score three months after teaching would be higher than six months later, was supported(t=2.43 : p=.020). 2. The relation of knowledge and self-care performance 1) The forth hypothesis, that the level of self-care performance related to diabetes three months later would be higher than six months later, was rejected( t=1.49 ; p=.146). 2) The fifth hypothesis, that the higher the diabetes knowledge, the higher the level of self-care performance, was rejected(r=.2086 ; p=.118). 3. The relation of diabetes knowledge and self-care performance according to demographic variables and structural variables of diabetes. 1) Diabetic knowledge scores varied according to the educational levels of the clients directly after the teaching. Three months after the teaching program higher educational levels and higher economic status were related to higher diabetic knowledge scores and men had higher knowledge scores than women. 2) Self-care performance scores of men were higher than those of women at three months and six months after the teaching program. 3) Before the diabetes teaching, the diabetic knowledge scores of subjects who had a diabetic patient in the family were higher than those who did not have patient in their family. Six months after the teaching, the diabetic knowledge scores of subjects who read the distributed books about diabetes were higher than those who did not read them. 4) No significance differences were found be-ween self-care performance and structural variables of dialetes. The results of this study indicated that the levels of diabetes knowledge and self-care performance incense of three months after the teaching program but decrease of six months. Reeducation would be needed between three and sir months. The investigator thinks that a study of the content and teaching methodology is needed to increase the education effect. The subjects want to hear patient histories of diabetic management. Group discussion would be helped after the teaching sessions.

This study was conducted to investigate the perception of teaching consulting and dietary education of Home Economics teachers. The subjects consisted of 139 Home Economics teachers in Korea. The perceptions of Home Economics teachers on their teaching class were as follows: the teachers who had a lot of psychological burden on their open classes, 62.6%; who were satisfied with their teaching, 29.5%; who had been teaching consulting, 40.3%; consulting is needed in order to improve the quality of instruction, 46.8%; who wanted to receive teaching consulting, 46.1%. who wanted to receive teaching consulting excellent colleagues, 76.3%. The most of the Home Economics teachers had a positive attitude on the teaching consulting. The perceptions of teaching strategies of dietary teaching classes were as follows: using audio-visual materials for students concentrate, 47.5%; observing the students reactions and feedback for individual variation, 73.4%; descriptive class for main teaching method, 58.3%. The difficulties of teaching dietary class were as follows: total mean, 2.60/5.00; considering individual differences, 3.26; involving students in activities, 3.11; selection of teaching media, 2.88; production of media, 2.88; planning teacher and student activities, 2.85. Home Economics teachers have to lead dietary education in society and schools but they feel a lot of psychological burden on opening teaching class. Therefore Home Economics teachers are recommended to devote consistent efforts to strengthen teaching ability through the analysis of teaching ability, teaching reflection, consulting and actual performance of self-supervision.
