The purpose of this study was to investigate high school students' learning style, perception of types of laboratory instruction, and the relationship between the learning style and preferred type of laboratory instruction. The participants of this study were 19 female high school students, from Incheon in Korea, who showed outstanding science grades. Dunn et al's revised Learning Styles Inventory (1997) was used for testing students' learning style. The students were asked to choose preferred and not preferred types of experiments and describe the reason of the choices after implementation of 4 types of experiments: verification, discovery, explorator, and investigation laboratory instructions. The findings of this study were as follows: Firstly, the students had a certain common learning style irrelevant to their personal characteristics, i. e; they showed high (self, teacher, parents) motivation and structure stimuli that was common in Korean students. Second, outstanding students prefer unstructured and open laboratory instructions. And those students were highly influenced by sociological and emotional stimuli. Third, students' learning style was related to their preferred type of laboratory instruction. Students preferring unstructured and open laboratory were influenced by sociological and emotional stimuli, while those preferring structured and closed laboratory were influenced by physiological stimuli.

The purpose of this study was to investigate the effects of science inquiry experiments emphasizing social interaction on the development of process skills of the students. The social interactions by cognitive level of the students were also analyzed. For this study, 197 8th grade students were sampled. They were divided into an experimental group and a control group. During four-month period, the experimental group received science inquiry experiments treatment emphasizing social interactions while the control group received traditional treatment. Not only science inquiry ability pretest-posttest, but also multiple data collection method such as a questionnaire, class observation, and audio/video recording were used in collecting the data. According to the results of this study, it was found that the mean score of the experimental group was significantly higher than that of the control group at 0.05 level. It was also found that the students of high cognitive level led the peers and participated in the class discussion actively with the teacher while the students of low cognitive level followed the students of high cognitive level and showed inactive interaction with the teacher. Analysis of the students' perceptions on inquiry experiments showed that students participated in discussion actively in the class as these experiments gave an opportunity for them to discuss and were able to solve the problems with peers' help through discussion.

In this study, the effects of a teaching strategy based on interactive formative assessment on students' science concept understandings and science-related attitudes were investigated. Students' perceptions toward this teaching strategy were also examined. Eight classes chosen from a co-ed middle school in Seoul. Four classes were assigned to the experimental group and the other four classes were assigned to the control group. After the instructions, tests regarding students' conceptions and science-related attitudes were administered. We also interviewed 24 students randomly chosen from the experimental group to investigate their perceptions toward the teaching strategy used. The results showed that the teaching strategy used was more effective for enhancing students' science concept understandings. However, there was no significant difference in science-related attitudes between the two groups. For the experimental group, no significant differences were found in the gain scores of the conceptions tests between the subgroups by previous achievement or cognitive levels. From interviews, it was found that students thought that the teaching strategy used encouraged much interactions and motivated them to think, and that teacher's appropriate feedbacks were helpful to their understanding scientific concepts.

The purpose of this study was to investigate the effects of experience as a science experiment assistant teacher on the science instruction anxiety and the science teaching efficacy beliefs of elementary pre-service teachers in a small scale school. For this study, 21 elementary pre-service teachers were selected and then they worked as science experiment assistant teachers in small scale schools for about 10 months. They were tested the science instruction anxiety and the science teaching efficacy beliefs in before and after. After analyzing the tests results, some pre-service teachers were interviewed. The results of this study are as follows. The experiences as science experiment assistant teachers positively influenced on reducing the science instruction anxiety to elementary pre-service teachers. The experiences also had positive effects on reducing both state anxiety and trait anxiety, which are the sub-factors of science instruction anxiety. In addition, the science teaching efficacy beliefs and its sub-factor, the self-efficacy in science teaching, had positive impacts, but the experiences did not have a positive impact on the outcome expectancy. The effects of the experience as a science experiment assistant teacher were different according to the personal experiences and cognitions of pre-service teachers.

The purpose of this study was to find out the factor that causes the difference on understanding the aim and perception of laboratory activities between teachers and students. For this study, in-depth interview was conducted for sixth grade students and teachers of 10 classes. The questionnaire of the interview can be divided into 3 sections: the aim of laboratory activities, whether teachers present the aim of laboratory activities, the method of laboratory class progress and the evaluation method. The factors that bring about the difference between the teachers and the students on perception of the aim are the absence of proper guidance on the aim of laboratory activities, the laboratory classes that the progress out of teachers' intention and evaluation method that is the performed without any relationship with the aim of the laboratory activities. Because the teacher-intended aim of laboratory activities is not properly presented, students can't percept the accurate aim. Even though teachers recognize the importance of the improvement of science process skill acquired through laboratory activities, this is not delivered practically in the class and students also can't percept the importance of science process skill.

The purpose of this study is to investigate the effects of science classes using smart devices that combine augmented reality (AR) and virtual reality (VR) on the scientific attitude of middle school gifted students. In addition, it is intended to find out the perception of science classes using these smart devices. In addition to actual experiments, a science class program that allows students to experience science experiments virtually using AR and VR was applied to 15 middle school gifted students. Before and after the application of the program, the questionnaire is to investigate the interest in scientific classes, the attitude toward science exploration, and the professional interest in science, and the recognition of classes that combine AR and VR. In addition, through in-depth interviews, the perceptions of gifted students was accurately investigated. As a result of this study, the content of science classes and instructors showed high class satisfaction, but the smart devices and applications used during the science classes showed lower class satisfaction than others. As a result of comparing and analyzing the pre-post of gifted students, interest in science class, attitude toward science inquiry, and professional interest in science increased significantly among the sub-areas of the scientific attitude test. As a result of analyzing free responses and indepth interviews, gifted students responded with the advantage that classes using smart devices that combine AR and VR can be tested quickly and safely for a short time compared to actual experiments. On the other hand, they responded with low completeness of the application and dizziness when operating virtual reality. Based on this, implications for the development of applications and instructional programs using advanced technologies that can experience realistically limited scientific experiments such as experimental preparation, class time, and risk factors were obtained.
