  • The purpose of this study was to examine 'orientations toward teaching science (OTS)' of science teachers and to analyze the factors affecting OTS found in middle school science classes. For this purpose, we selected three female teachers as participants named Kim, Ryu, and Park who had various teaching experiences. Semi-structured interviews and classroom observations were gathered for data. After analysis of the characteristics of the teachers' orientations toward teaching science from the data, the factors affecting the orientation were investigated. As results, three types of orientation toward science teaching were observed: inquiry, activity driven, and didactic. These types of orientation toward science teaching were affected by internal factors rather than external factors. The internal factors found out were experience as a student, understanding of the nature of science, curiosity, and reflective thinking.

  • Recently performance assessments have been recommended as an alternative to traditional assessment methods such as multiple-choice written test. Performance assessment is suggested to facilitate students' creativity, participation and learning motivations in science classes. In this study, performance assessment materials were developed for a biology unit of middle school science 1, 'Plants Around Us', and then the assessment materials were applied to assess students' understandings and attitudes related to each topic of the unit. A total of 186 7th grade students at a southern large city participated in this study. From the study, the following were obtained: 1. Various type of the performance assessment materials, such as observation report, peer evaluation, interview have been developed for the unit 'Plants around us.' 2. Students' understandings on the topics appeared to be sound, and the students' interest and cooperative problem-solving abilities have been cultivated through the small group activities. The science classes became more student-centered. 3. Teacher's burden has increased due to the practices of performance assessment, but it could be handled by teacher's commitment and management skills. 4. The students' responses to performance assessments were positive, in general.

  • Since 1960' s. aims of science education have changed from attainment of scientific concepts. principles and laws to improvement of science process(or inquiry) skills. According to the science education philosophy like this. our nation has adopted improvement and evaluation of science process(or inquiry) skills in science education. The purpose of this study was to examine the performance of high school students on 4 types of multiple choice items used to access students ability to identify independent and dependent variables. Stimulus materials were either a question focusing on the relationship between two variables. a hypothesis. a description of an experiment. or a description of results of an experiment. Student performance on these item types was compared to this performance on a standard Piagetian interview task of variable identification. The results of the study included: (1) the "hypothesis" type was the most difficult, while the "question" type appeared to be the easiest; (2) the "procedure" item type had a higher correlation with the total interview than any other item type. Among conclusions reached in this study was that although all four item types operated similarly. they did not correlate very highly with the performance assessment by interview.

  • The purpose of this research was to analyze characteristics of verbal interactions of each homogeneous group in the learning of the 6th grade's 'Use of Lenses' Unit. For this research, six learning sessions were conducted in one 6th grade class composed of a high-academic-achievement group, an intermediate-academic-achievement group, and a low-academic-achievement group. All lessons were recorded, to analyze the verbal interactions of each group, and the transcribed data were analyzed using the verbal-interaction analytic framework. Results included: In the upper group, although opinions were presented more frequently, there were many negative verbal interactions in completing the tasks. The middle group was observed more specifically to accept peer opinions critically in their observational activities. The middle group's members were more active in presenting their opinions than listening to others' opinions. The lower group had difficulties in drawing conclusions because of a lack of ability to persuade peers or to respect the opinions of peers, even though the frequency of verbal interactions was higher than in other groups. Therefore, a homogeneous group structure is good for a simple activity involving a simple inquiry or an exchange of opinions, while a heterogeneous group structure is more effective in activities focused on understanding scientific concepts and knowledge.

  • In school science class, actual geological field trips tend to be restricted due to a number of problems including travel distance, cost, safety, and so on. Therefore, alternative way should be sought to provide students with the benefits of actual field trip. The purpose of this study is to develop web-based virtual field trip (VFT) about Jeju island in Korea by using flash panorama, and to explore a variety of ways to utilize the VFT. The characteristics of Jeju VFT are as follows: it provides virtual space for secondary school students to learn about volcanic topography and geology; students can access contents in a non-sequential order by virtue of web-based system, and students can control learning pace according to their ability; it is possible to investigate the same field site repeatedly, not limited by time and space; it presents differentiated worksheets for different school grade; it provides diverse complementary web contents, e. g., closeup features, thin sections, inquiry questions, and explanations of outcrops. We proposed several ways with instructional models to utilize Jeju VFT in science class and extra-school curricular as well.

  • The purposes of this study were (1) to investigate the characteristics of the exhibits at three representative science centers or museums in Seoul, and (2) to analyse students' perceptions about the most and the least favorite exhibits selected by students as visitors. Three science centers investigated were Seoul National Science Museum, Seoul Education & Science Research Institute, LG Science Hall. The subjects for students' perception survey were 290 middle school students who visited the three science centers. The investigation of the exhibits showed that the goals, the contents, the visitors' viewing and manipulating activity types, and the explanation types of the exhibits depended on the purposes and the target visitors of each science center. Students' responses indicated that they most favored hands-on exhibit. And students preferred the exhibits that had new and comprehensible contents and the were related to what they had learned in school. Students said that they felt that science was exciting and that they came to experience what they did not do in school. Students said that reading or hearing given explanations was helpful to understand the exhibits, but about 20% of the students responded that they did not read explanation on panels at all. Students also said that guide's oral explanations were more understandable than written explanations on panels. Some of the students commented that having to wait for access because of crowds or because of the resetting time required for hands-on activities was inconvenience.

  • This study analyzed perceptions and difficulties in applying Flipped Learning with an interview method grounded on understanding and experience of Flipped Learning in science class. The interviewees selected were six teachers working in Seoul and Gyeonggi Province. Three teachers having over two years of experience in operating Flipped Learning in science were selected, one each from elementary, middle, and high school and another three teachers who had just started to operate Flipped Learning this year were chosen, one each from elementary, middle, and high school. According to the result of a 3-step interview conducted with the participating teachers, they indicated very high satisfaction with the implementation of Flipped Learning in elementary, middle, and high school science classes. They responded that Flipped Learning was particularly more helpful for inquiry activity. The teachers, however, felt burdened by the class preparation and had difficulty in organizing the class. To explore ways to get rid of the difficulties in Flipped Learning, this author discussed the textbook system where one could draw various implications for improving the current class.

  • This is a study on science related class(Object Lesson in Germany) of a German elementary school. The research methods were participant observation, content analysis of various learning materials. In this study, the themes and processes of the Object Lesson are analyzed from the 1st grade to 1st semester of 2nd grade in B-G Schule at Goettingen. German Object Lesson(GOL) is performed as integrated education. It is started with experientially familiar materials and proceeded to deeper contents with special knowledges. The students have lots of time to play with friends, to do what they want, to think about others and etc. in GOL. They don't teach their students many science knowledges but inquirying methods to make their own knowledges. From this analysis results, the implications for Korean science education are to be described. The implications are as follows; We might make our science class be integrated one, especially in elementary science course, to develop several familiar materials, to give student direct experiences, to teach inquirying methods for making students' own science knowledges. And all of the adults included national authorities, economic companies, social parties, several specialists, should give supplies to school science class and have responsibilities on education
