In this study, we developed the selection criterion of physical computing teaching aids for middle school SW education. Literature analysis, Delphi survey, and AHP methods were applied to develop the selection criterion. First, seven characteristics for physical computing teaching aids have been set up by the literature analysis. The contents are suitability for curriculum, safety, durability, economy, general availability, attractiveness, and ease of management. Based on these characteristics, the Delphi method is used in developing 31 criteria in 7 areas for the selection of physical computing teaching aids. Next, the AHP method was applied to identify the relative importance between 7 areas and between 31 detailed criteria. And then the final criterion for the selection of physical computing teaching aids was developed by calculating scores for detailed criteria.

The superiority and safety of eco-friendly agricultural products are well-known. The purpose of this study is to provide fundamental data for creating a safe food culture, to improve the quality of school food services, and to increase student satisfaction with school food services. We compared the perception of eco-friendly agricultural products and food service satisfaction between students with and without exposure to a dedicated event for learning about eco-friendly products (an Eco-friendly Food Service Day) in elementary and middle school. When students were asked to define eco-friendly products, "organic products" was a highly frequent response in schools with an Eco-friendly Food Service Day, while "pesticide-free products" was a highly frequent response in school without this event. For most students, a factor in choosing eco-friendly products was a quality certification mark. Students from elementary schools with an Eco-friendly Food Service Day had a higher frequency of using eco-friendly agricultural products at home compared to students from schools without the event (p<0.01). In addition, the satisfaction with school food service was higher in schools with an Eco-friendly Food Service Day (p<0.05). These results suggest it is important to promote the use of superior and safe eco-friendly agricultural products while developing a variety of menus considering students' preferences.

This study was conducted to evaluate the effects of a Motivation Enhancement for Smoking Cessation Program on middle school students' knowledge regarding smoking, self-efficacy, and daily amount of smoking. The study used a nonequivalent control group pre-post-test design and included 47 students who smoke from two middle schools located in city U as subjects. Subjects were separated into two groups, an experimental group with 23 students and a control group with 24 students. Data were collected from February 19, 2018 to May 11, 2018 and analyzed using the IBM SRSS/win 24.0 program to conduct a t-test, ${\chi}^2$-test, Fisher's exact test, and a paired t-test. After subjects went through the Motivation Enhancement for Smoking Cessation Program, their knowledge regarding smoking (t= 3.38, p=0.002), self-efficacy (t= -3.37, p=0.002), and their daily amount of smoking (t=3.38, p=0.002) showed significant changes. The results indicate that the Motivation Enhancement for Smoking Cessation Program is effective at increasing subjects' knowledge regarding smoking and self- efficacy while decreasing their daily amount of smoking. Therefore, to induce cessation of adolescent smoking, Motivation Enhancement for Smoking Cessation Programs tailored to each student should be held.

This study investigated the current status and needs of career counseling based on the student's perception of specialized vocational high school in Daejeon. The main purpose of this study is to provide the future direction and improvement strategies of career counseling in specialized vocational high school through the evaluation of current situation and student's needs. The analysis results of this study are as follows. First, most of students decided their admission into a specialized vocational high school when they were three grades in middle school. It indicates that career counseling teacher plays important roles during that time. Thus, it is necessary to strengthen the ability of career counseling teachers and to develop the various programs to seek student's aptitude and talent from the period of middle school. Thus, it is necessary to strengthen the ability of career counseling teachers and to develop the various programs to seek student's aptitude and talent from the period of middle school. Second, since most of career counseling takes place primarily with class teacher, professional counseling education for class teachers is required. It also needs to expand the specialized counselors to reduce the overburden of class teachers and develop various counseling programs. Third, vocational high school students need the specialized counseling programs according to their major. Effective group counseling programs as well as one-on-one counseling programs which can help the student's career decision should be developed.

The purpose of this study is to analyze how the teaching activities which used EXCEL influence the specialized high school underachieved students. They have difficulties in making use of various representations for better understanding of function. EXCEL is helpful for learning function because it enables the students to use real life materials in math learning as well as formulates Tabular, Algebraic and Graphical which represent function. Furthermore, the students in specialized high school also have the experience of using EXCEL while studying other subjects. For that reason they have no burdens and fears on using EXCEL in learning activities. Utilizing EXCEL in the classroom gives an expectation that it helps to have interests on studying function and prepare for the next learning in the end. Research classes were conducted in a group of five students who have different hopes of career and a variety of mathematical interests. Though the students couldn't transfer Algebraic to Graphical in the diagnostic evaluation, they could resolve the problem of connections between Graphical, Tabular and Algebraic in the process perspectives, and could also express graphical representation by linking object perspectives with process perspectives. Therefore, they solved the connection problem of Tabular, Algebraic and Graphical in the object perspectives. As a result, the students could make transitions between Algebraic and Graphical in object perspectives through the classes applying EXCEL. Consequently, teaching the students with underachievement utilizing EXCEL enables them to recover their interests on math and it helps them to complete their following curriculum.

The purpose of the study was to investigate which psychological factors influence on the gifted students' achievement. As a psychological factor, self-determination, learning goal-orientation, self-efficacy, belief of intelligence, and self-regulated learning strategy were examined. The difference in psychological factors between the gifted with high achievement and the gifted with low achievement was to explored. For the study 128 gifted students' data from second-year data of Korean Education Longitudinal Study (KELS) were selected and analyzed. The findings indicate that the predictors of gifted students' achievement are extrinsic regulation, identified regulation, mastery-approach goal, self-efficacy, elaboration, and meta-cognition factor. Especially, the factor of elaboration and identified regulation are the strongest predictors. The findings from t-test analysis indicate that the gifted with low achievement show the low level in self-determination, mastery-approach, self-efficacy, elaboration, meta-cognition, place management and seeking social assistance from teacher. Therefore the developing elaboration, one of regulation learning strategy, is essential to improve the achievement of the gifted students with low scores.

The aim of this study was to examine how analogical mapping articulation activity played a role in solving process in word problems. We analyzed the problem solving strategies and processes that the participating thirty-three 8th grade students employed when solving the problems through analogical mapping articulation activities, and also the characteristics of the thinking processes from the aspects of similarity. As a result, this study indicates that analogical mapping articulation activity could be helpful when the students solved similar word problems, although some of them gained correct answers through pseudo-analytic thinking. Not to have them use pseudo-analytic thinking, it might be necessary to help them recognize superficial similarity and difference among the problems and construct structural similarity to know the principle of solution associated with the problematic situations.

The purpose of this study was to test whether the degrees of desyncronization in cranial nerves were related to correlation coefficient between brain waves measured on scalp. Based on the hypothesis. this research intended to describe the patterns of brain wave during scientific reasoning. EEG (electroencephalography) signals in 19 electrodes were recorded from elementary (6th grade) and middle (7th, 8th grade) school students as they performed roller-ball tasks: planning experiment, cognitive conflict, bridging, metacognition, and at rest (eyes closed and eyes opened). The results showed that the smaller the correlation coefficient was, the bigger the degrees of desyncronization. As compared to resting periods, the correlation coefficients in prefrontal and frontal lobe decreased during scientific reasoning. And the nerves in prefrontal and frontal lobes were most active during scientific reasoning. These results suggest that the correlation coefficient in addition to frequency of brain waves be analysed to get meaningful results of researches on scientific reasoning by brain wave.
