The purpose of this study was to improve the interest of food and nutrition area in Technology Home Economics subject as well as food safety and choice. For that, we developed new teaching-learning plan by using reading education method and applied to the 9th grade students in Buchun, Kyunggi-do. Experimental and control groups were selected based on their test score in nutrition section. Control and experimental groups were educated by general lecture or reading education method for 4 weeks and the effect of different educational methods was tested. The results of study as follow: First, teaching-learning plan by using reading education method has been developed. To apply reading education method, we developed reading record cards which could help students to understand the terminology and nutritional problems. In addition, students had time to discuss about food safety and choice after reading education which could improve the interest in Technology Home Economics subject and communication skills. Second, after applying the developed lesson plan, the results showed that reading education method improved the interest and attitude about Technology Home Economics subject and teacher, and food choice attitude. However, reading education method had no effect on the interest on reading book about food and nutrition, and These results suggested that reading education method improved the interest and recognition about Technology Home Economics subject and teacher and food choice attitude. Therefore, to establish the proper dietary behavior in junior high school students, we need to develop and apply diversity of teaching-learning plan by using reading educational method.

The purpose of this study is to confirm the effects of the learner-centered instruction based on constructivism on learners' reasoning ability and their achievements which is closely related to reflective abstracting ability. To do it, learner-centered instructions for division was implemented, recall test, generation test, content reasoning test I and II were carried out. The following conclusions were drawn from the data we got. Experimental group(EG) improved their reasoning ability, while comparison group(CG) did not. EG showed statistically significant difference in the achievements of the contents learned in comparing with CG, and the difference in the achievements of the contents unlearned in the treatment in comparing with CG was higher than the one. In addition, the comparisons of the subgroups(high, middle, and low) between EG and CG showed that the treatment had a positive influence on the achievement to all subgroups in EG. That is, the treatment was effective for unable learners. Finally, EG showed statistically significant difference in the sub-domain of simple calculation which might be considered as the benefits of the treatment of the CG as well as in the sub-domain of concept and principle.

In the era of the 4^th industrial revolution and convergence, various discussions and studies have been conducted to develop future social talents, and through this, the need for creative convergence talents is increasing. In line with the change to a software-oriented society, countries around the world are trying to strengthen SW education, but high school students' awareness of the necessity of information subject and SW education that is the center of convergence is insufficient. Therefore, opportunities for convergence of the information subject and various fields should be provided. In this study, information education was converged to the science exploration experiment subject to construct an educational program that can develop creative convergence, and a convergence class using physical computing were applied to high school students for 9 hours. As a result of the experiment, the recognition of SW education of the experimental group was improved, and it was confirmed that the learner's convergence literacy of the experimental group was statistically different from that of the control group that conducted the general science experiment class.

The purpose of this study was to investigate the effects of Science Writing Heuristic (SWH) laboratory class on the creative thinking and critical thinking of middle school students. Science writing heuristic programs were developed based on SWH strategies developed by Keys et al (1999). This study was conducted on 63 students from two classes as the comparative group and 63 students from two other classes as the experimental group. The cognitive level of the group as a homogeneous group was similar, and the program was applied to a total of 18 periods based on nine topics from March to July 2011. Evaluation instruments used in pre-test and post-test were the creative and critical thinking tests. To consider the score for creative and critical thinking. the SPSS 20.0 program was used. The study made use of technical statistics and ANCOVA. The result of this study showed that creative problem solving skills were improved by SWH in laboratory class. Therefore, persistent presentation of SWH teaching strategies and developing various experiment topics are required.

The purpose of this study is to verify influences of a cinema psychotherapy class containing a discussion on improving the emotional intelligence and empathic ability of university students. The research subjects were divided into a test group and a control group, with 106 students in each group. For a semester, the test group attended a practice-centered course including cinema psychotherapy, while the control group attended a discussion on personality psychology theory. The test group was shown 6 films in 12 weeks and answered structural questions between the researcher and subjects, and nonstructural questions between subjects. The results were as follows: The test group showed significant increases in self and other emotion appraisals in the emotional intelligence field. On the other hand, there was no significant change in emotional intelligence among the control group. With respect to empathic ability, the test group showed a significant increase in cognitive empathy, perspective taking, fantasy, and emphatic concern, while the control group didn't show significant change in empathic ability. In post-test, the test group demonstrated a significantly higher ability in cognitive empathy and perspective taking compared to the control group. This study verified that an interactive cinema psychotherapy class can increase emotional intelligence and emphatic ability. This study also demonstrated the effectiveness and necessity of a cinema psychotherapy class. As the class improves, more factors of emotional intelligence and empathic ability can be addressed.

A research problem for this study is formulated: "Is practical reasoning instruction effective on raising problem solving ability?" This study is a quasi-experimental study with independent variable of practical reasoning instruction and dependent variable of problem solving ability. Six class hours of experimental input for the 'Housing space' is implemented for an experimental group. T-test results show that practical reasoning instruction is effective on total problem solving ability whereas is not effective on 'implementing alternative action' sub-area of problem solving. This study suggests for the future studies to systematically design practical reasoning classes in consider of appropriate class times and sub-areas of problem solving. Input of an experienced teacher of practical reasoning is also recommended to generalize the results of the experimental study.

Although cooperative learning strategies in many subject areas have been found to be effective, the effect of cooperative learning on academic achievement in science laboratory setting is not clear. Reported results on the effects of the strategies for higher achieving students are not also consistent. In this study, the cooperative learning strategies emphasizing student-centered learning which included higher order thinking activities were used in a elementary school science course. The cooperative and traditional learning groups were selected from fifth-grade classes, and taught about dissolution and solution for 16 class periods. The effects of the cooperative learning strategies upon students' academic achievement, science process skill, the attitude toward science instruction, and the perceptions of classroom environment were investigated. Two-way ANCOVA results revealed that the test scores of academic achievement and science process skill for the cooperative learning group were significantly higher than those of the traditional learning group. No interaction between the instruction and the level of previous achievement was found. The perceptions of confliction were higher in cooperative learning group. In the attitude toward science instruction and the perceptions of participation, however, no significant difference between the two groups was found. Educational implications are discussed.

This study explores how the positioning of two pre-service science teachers (PSTs) is reflected in their different epistemic understandings of inquiry-based lessons. We collected the PSTs' products during their design and enactment of an inquiry-based lesson and recorded their practices in the enacted lesson. Interviews were recorded and transcribed for analysis. The results indicate that one PST, Dohyung was positioned as a subject of evaluation throughout the course and the other, Jinwoo, was positioned as a preservice teacher and a subject of evaluation. Their positions were reflected in their epistemic understandings of inquiry-based lessons, which were developed when designing these lessons. During lesson design, both PSTs showed a shared understanding; they explained inquiry-based lessons as students setting and evaluating hypotheses under teachers' guidance. However, as they faced unexpected situations during lesson enactment, they developed different epistemic understandings. To receive a good grade, Dohyung showed a strong preference for anticipating situations that could occur in class and planning responses to them. He understood inquiry-based lessons as ones in which students conduct experiments to produce results expected by the teacher. On the other hand, Jinwoo emphasized the reasoning process based on students' prior knowledge and explained inquiry-based lessons as ones in which students construct new knowledge through a scientific reasoning process based on their knowledge. The findings of this study will contribute to developing strategies to support PSTs' development of their epistemic understandings of knowledge construction in inquiry-based lessons.
