현대 교육은 단순한 암기 위주가 아닌 첨단 컴퓨터를 이용한 실험 실습 위주의 직접 보고 듣고 느끼는 방향으로 진보하고 있다. 실험 실습에 의한 과학교육은 사용자의 탐구능력 향상과 과학적 태도 향상에 중요한 역할을 하게 될 것이며 기존의 암기위주나 단순한 수치에 의한 개념 학습을 탈피하여 Data collection 기술과 분석의 활용을 통해 사용자가 과학을 좀 더 이해하고 사용할 수 있도록 하는 능력을 증진하게 한다. 이를 위한 과학교육의 한 방법으로 MBL(Microcomputer Based Laboratory)은 실험자가 실험실이나 야외에서 각종 기구를 사용해 데이터를 습득할 수 있도록 도와주는 컴퓨터 기반 과학 실험 시스템으로서 미국, 영국 등 과학 교육 분야에서 추구하고 있는 세계적인 추세라고 할 수 있다. 이러한 MBL 시스템의 구성은 센서를 통해 얻어지는 자료를 컴퓨터에 전달하는 매개체인 인터페이스, 과학 실험에서 발생하는 데이터를 직접 전기적 신호로 변환하여 인터페이스에 전달하는 센서, 인터페이스에서 전달되는 전기적 신호를 컴퓨터 화면에 나타내어 주는 컴퓨터용 전용 프로그램으로 구성된다. 이러한 MBL을 과학교육에 활용한다면 학생들이 스스로 과학적으로 탐구하고 문제를 해결할 수 있는 능력을 배양하는 데 많은 도움이 될 것이다.

The purpose of this study was to examine the effects of formative assessment with detailed feedback on students' science achievement, attitude, and interactions between the teacher and the students. For the study, 133 seventh graders were selected from a girl's middle school in Seoul, and assigned to the experimental and the control groups. The duration of the treatment was over a period of nine weeks. In the experimental group, detailed feedbacks on the solution, teacher's comments on the results, and relevant references were provided after each formative assessment. However, only the answers were presented in the control group. Prior to instructions, a achievement and a attitude tests were administered. After the instructions, follow-up tests which were similar to the pretests were also administered. The results showed significant difference between the two groups in science achievement. It was found that the usage of formative assessments with detailed and supportive feedbacks was more effective in stimulating students' interest, raising their confidence in the subject, increasing their participation, as well as reducing their anxiety. The results also strongly indicated that detailed feedbacks were more effective in improving the interactions of the teacher and the students. The results strongly suggest that formative assessment utilizing detailed and supportive feedback is a necessary component of effective science teaching and learning.

In this study, we used Virtual Reality (VR) materials on an introductory earth science course consisted of thirty six pre-service science teacher program students. Before and after class an instrument of Constructivist Learning Environment Survey (CLES) was administered. The main focus of the CLES was to evaluate how the classroom was prepared for student centered learning environment. The pre and post tests of student perceptions regarding their learning environment were compared in six domains: personal relevance, critical voice, shared control, student negotiation, scientific uncertainty, and attitude. Questionnaire regarding the general perception of the VR materials was administered as well. How future science teachers valued the use of VR materials in their classrooms was found from this study. Based on these results, we intend to contribute for a more complete understanding of the potential of VR materials in achieving better learner-centered classroom environment.

In this study, students' perceptions on small group activities in science classes were investigated. The relationships among students' values of and attitudes toward small group activities, gender, prior achievement level, and personality were also studied, Subjects were 226 students from four middle schools in which group activities were frequently used in science classes. In their classes, groups were mainly formed by teacher on the basis of grade and student number, or by drawing lots. Many students were dissatisfied with the grouping methods, preferred to make a group based on their friendship, and hoped that there would be different levels of knowledge among the members. Regardless of their gender or prior achievement level, students perceived positively on small group activities. Students with higher agreeableness and extraversion had higher values of and positive attitudes toward small group activities. Among five personality variables studied, agreeableness was the only one that significantly explained both values of and attitudes toward small group activities.

The purpose of this study was to analyze the controversial points in the concepts of materials in the science textbook of middle school and to provide alternatives of teaching method. For this study, units in connected textbooks were analyzed and the teaching method using ball-and-stick models was developed. The subjects were 130 second graders from a middle school in Seoul, Korea. It aimed to compare the effectiveness of using ball-and-stick models for lesson with the one of traditional lessons, in learning concepts concerning materials by cognitive levels and to investigate the difference of scientific concept formation about concepts concerning materials by their cognitive levels between experimental group and control group by using concept formation questionnaires. Before the instructions, a short-version GALT was administered. After instructions, the posttest of concepts and attitude test connected with science subject were administered, and 10 months later, the posttest of concepts was administered to analyze the long-term memory effects. According to the results, the experimental group using the ball-and-stick models had significantly higher scores at conceptual understanding and long-term memory effects than the control group and improved the attitude relevant to science subject, and also had affirmative effects in attitude for science and science work. When analyzing the results according to the cognitive level, the long-term memory effects was high in the concrete operational stage students. From the results of this study, middle school students that are more concrete operational stage and transitional stage than formal operational stage elevates interesting in studying by using ball-and-stick models and making material form concretely. It would be effective in helping the students develope the correct concepts by connecting real world as materials and the particle world as atom.

The purpose of this study was to analyze laboratory instructions in a secondary school science with an analysis instrument on science laboratory instruction. For its purpose, we used an instrument that analyzes three dimensions of the secondary laboratory instructions. This analysis instrument was composed of 3 categories (the aim of the laboratory activity, interaction, and inquiry process) which are spread into 20 sub-categories, and its validity was checked by four science educators with factor of 0.89. For its purpose, 21 sessions of lab instructions were video-recorded and transcribed. According to the results, in the aims category, the instructions mainly focused on two aims; acquiring the declarative knowledge and increasing attitudes toward science. In the interaction category, some of the observations made were that the teachers's questions could not gather the students' divergent thinking, their directive instructions were centered around themselves rather than giving opportunities for students to be centered within laboratory activities, and students' interaction were rarely shown. Therefore, interaction was classified as level I. In the inquiry process, presenting phenomenon or questionings about the subjects were little observed, and students' hypothesizing and predicting were almost nonexistent. Most of the activity designs within lab session were given from the teachers' directions or worksheets, and students solely focused on data collecting and recording. Hence, inquiry process were classified level I.

This study aimed to develop an HTE (It is an abbreviation for Here, There, and Everywhere) STEAM program combining with the use of an analogy in a middle school subject unit 'the solar system' and realize creative education for intelligent information society through a process of verifying the effectiveness of the program. For reference, the program was applied to 354 students in the first grade of two middle schools in South Korea - one was A middle school in Sejong City, the other B middle school in Pyeongtaek City. The STEAM program was revised and made up for the weak points for three times by a group of experts, and then it got verified for validity. The final version of the program was applied to middle school education sites in Korea for six periods in total. In other to confirm the effectiveness, two types of tests - logical thinking ability test and STEAM attitude test - were conducted before and after the program treatment. On top of that, the STEAM satisfaction test was also implemented in order to explore the students' recognition of the program after the program treatment. The results of this study were as follows. First, it turned out the STEAM program using the analogy was effective in improving the students' logical thinking ability. Second, the STEAM program blended with the analogy was also effective in improving the students' STEAM attitude. Third, the students' recognition of the STEAM program using the analogy was quite positive, and the program was efficacious in intriguing the students' interests in science. Judging from the results of the program, the students' satisfaction with the classes they take will be expected to be higher if the STEAM program is implemented in the next-term classes with more sufficient time.
