  • This study is to investigate the effect of pre-primary teachers' gender and earth science completion while attending high school on the diversity of concepts, the level of conceptual understanding, and misconceptions about seasonal changes. This study was conducted with 71 pre-primary teachers. The conclusion of this study is as follows. First, the area of concepts used by pre-primary teachers to explain seasonal changes showed a greater difference depending on whether or not they completed earth science while attending high school, rather than depending on gender. Second, although there was no significant gender difference in the conceptual level of pre-primary teachers for seasonal change, the group who completed earth science while attending high school had a statistically significantly higher level of conceptual understanding than the group that did not complete it. Third, the ratio of misconceptions related to seasonal change of pre-primary teachers by gender was not significant, but the group who did not complete earth science while attending high school had a statistically significantly higher percentage of misconceptions than the group that completed it. As a result of the above examination, it is judged that the area of concepts, the level of conceptual understanding, and the misconceptions about seasonal changes of pre-primary teachers are more affected by the completion of earth science courses during high school than by gender differences.

  • This study aims to explore how teachers construct scientific explanation during instructional practices to help students' scientific inquiry. Before investigating teachers' classroom practices, elementary school science curriculum was examined to identify scientific concepts, particularly in earth science. Then, a total of six teachers' scientific explanation in actual teaching practices was analysed focusing on a) explanation of scientific concepts; b) rationale for scientific explanation; c) connection between scientific explanation and everyday explanation. The findings are as follows. First, the science curriculum provides $1{\sim}2$ main scientific concepts per unit, which are mostly appeared in the unit title. Those concepts and sub-concepts are not explicitly described but embedded in students' inquiry activities. Second, the teachers explain scientific concepts and discuss the rationale behind the scientific explanation, but rarely connect scientific explanation to everyday explanation. Also, the level of scientific explanations is low remaining level 1 or 2, not reaching 3, the highest level. Based on the results, the study suggests a) teachers need to provide explicit and clear explanations about scientific concepts; b) teachers are required to connect scientific explanation and everyday explanation; c) the level of teachers scientific explanation should be elevated by using an evidence, reasoning and claim, the components of scientific explanation as well as introducing new scientific concepts and inquiry activities.

  • Pre-service teachers' understandings on magnet was investigated through the questionnaire method. The questionnaire was composed of 17 questions about the strength of magnet, the magnetized object and the direction of magnetic field around magnet. In this investigation study, 225 pre-service teachers were selected through random sampling method, who were sophomores in a National University of Education. The formation rate of the scientific conceptions on the strength of magnet was 30.3% and that on the direction of magnetic field around magnet was 53.9%. The average formation rate of scientific conception of all questions on magnet was 44.13%, which doesn't seem to be high as expected. It shows that many of subjects of the questionnaire don't understand fully the concept of moleclar magnet model and the superposition effects of magnetic field around magnet. The formation rate of the scientific conception on magnet of females who took courses in sciences in high school were higher than that of females who took courses in arts in high school, which had meaningful difference (p<.05).

  • The purpose of this study was to investigate the practical use of process skill under the seventh curriculum at secondary school and teachers' perceptions about hypothesis. Two hundred and twenty-two secondary science teachers responded to a survey. Among all process skills, data interpretation was found to be used most frequently by science teachers. The second most-commonly utilized skill was conclusion, and the least employed skill was hypothesis formation followed closely by data transformation. In addition to these results, the most difficult process skill practised by science teachers was hypothesis formation, followed by data transformation, and controling variables. A majority of science teachers (63.1%) properly defined hypothesis, but only a significant number (5.0%) chose the correct example about hypothesis in real-world contexts. More than ninety percent of science teachers believed the skill of hypothesis formation could be put to use in junior high to senior high school, but practical use of the skill, was too difficult for the science class

  • This study was designed to make valuable suggestions for the development of environmental education(EE) teaching materials through teachers' and students' opinions. In the summer of 2005, an opinionnaire was sent to 1,749 secondary school EE teachers and 270 teachers of them answered. One hundred and six middle school students and 196 high school students in Kyunggi area were also participated in this survey. The opinionnaire in this study was based on the six standards, fairness and accuracy, depth, emphasis on skill building, action orientation, instructional soundness, and usability, developed by NAAEE(1998). Most teachers were totally dependent on textbooks in their teaching EE. They evaluated current EE textbooks most positively in the perspective of 'fairness and accuracy', whereas they evaluated them most negatively in the perspective of 'usability'. The problems of EE textbooks were differently recognized by teachers and students. The lack of contents stimulating students' interest was considered as the most serious problem of EE textbooks by students. Simultaneously, it was considered as the least serious problem of EE textbooks by teachers. Both EE teachers and students expect the future EE textbooks would consist of proper contents to reflect EE characteristics.

  • The purpose of this study is to analyze middle and high school technology teachers' recognition and educational need about engineering education. For this, we surveyed secondary school technology teachers. The result of this study is as follow. First, most technology teachers perceive that engineering contents are lack in technology education, therefore they recognize the needs of reinforcement of engineering contents. Second, most technology teachers perceive that present technology subject does not give positive affect to students for their own career selection on engineering field. Furthermore, they perceive that if it contained the contents of engineering in technology education, students would experience creative design and problem solving process. Third, most technology teachers perceive that they are able to teach engineering in technology education and they need the change of national curriculum and the development of engineering program contents. Fourth, they perceive that the 7~9 grade is the best grade to start to study engineering in elementary and secondary school. Fifth, they perceive that 'design', 'problem solving' and 'creative thinking' are the priority of educational needs of teaching ability and knowledge about engineering. Sixth, they perceive that the aerospace engineering, the electrical engineering, the electronic engineering, the mechanical engineering, the computer engineering and the environmental engineering are the priority of educational needs of teaching knowledge about engineering fields.
