The main purpose of this study was to develop a teaching program, especially designed to improve the skills of control variables. The secondary purpose was to investigate the effect of the program on enhancing students' scientific reasoning and understanding. The program was designed based on the 3-step learning model: i.e. students recognize the necessity of controlling the variables (step 1), perform their own experiments (step 2), and reflect on their variables control process (step 3). The program included 9 topics of increasing difficulty. In results, Lawson's SRT scores increased in both experimental and control groups after application of the program, but the difference was not statistically significant. After the application, there was an increase in type A and type B which implied that students' skills of control variables was improved. In addition, responses of students in the experimental group to the open-ended items showed that it was challenging for them to think scientifically and critically when controling variables, but they ended up feeling proud of their achievement after the program.

In this study, we develop 15 learning programs to enhance the variable identification and control abilities for the middle school students and analyze the effect of the programs applied to the class. To increase the learning effect of the variable identification and control abilities, we design the programs so that the students can monitor their thinking processes and also they can evaluate the results from their cognitive activities objectively. We analyze the effect of the programs applied to the class and the results show that the test group, which uses the program, marks higher scores in the variable identification abilities compared to the control group. Also, the test group has the increased level of logic to control the variables. Especially, the effect is higher with the students who do not have any logic to control the variables. From the results, we know that it is possible to improve the variable identification and control abilities of the students through the meta-cognitive learning programs developed by us. Furthermore, the results show that the score of variable control abilities positively correlate with that of meta-cognitive level. It means that the meta-cognitive strategy meaningfully increases the variable control abilities of middle school students.

This study examined the effects of students'perceptions of classroom on self-regulatory strategy use, persistent intention, and achievement in an online Science gifted program. The sample included 434 middle and high school students who participated in the 3-months online gifted program. Participants volunteerly surveyed on their perceptions of classroom (appeal, challenge, choice, meaningfulness, academic self-efficacy), self-regulatory strategy use, and persistent intention. Student achievement data was collected from online learning system. Multiple Regression was conducted to analyze the effect of students'perceptions of classroom on various dependent variables. The results of this study showed that (1) students use of rehearsal strategy was positively related to academic self-efficacy among the sub-variables of students'perceptions of classroom and the use of rehearsal strategy was negatively related to challenge; (2) the use of elaboration strategy was positively related to challenge and meaningfulness; (3) the use of time management strategy was positively related to academic self-efficacy and the use of resource management strategy was positively related to challenge; and (4) students' persistent intention was related to appeal, challenge and meaningfulness, achievement was related to challenge.

The purpose of this study is to investigate the differences between children's internal variables (gender, temperament, development) and environmental variables (teaching efficacy, teaching - child interaction, classroom environment) The data collected for this study were analyzed using descriptive statistics, reliability analysis, correlation analysis, cluster analysis, and t-test using the SPSS 22.0 program. The results are as follows. First, the peer interaction of the infant showed a difference in sex between the types. Second, children's peer interaction showed differences in interstitial temperament, language development, and cognitive development. Third, the peer interaction of young children was different between the types of environment variables such as teaching efficacy, teacher - infant interaction, and classroom environment. As a result, it is suggested that the children's social temperament will lead to healthy peer interaction, and that language development and cognitive development will lead to a positive developmental process. In this study, the meaning and meaning of children's intergenerational behaviors in children's gender and temperament, language and cognitive development, and environmental variables such as teaching efficacy, teacher - infant interaction, I checked. In addition, it is meaningful that the positive and negative peer interactions are segmented and analyzed in detail to examine the peer interaction of infants. However, the limitation of this study is that it is not possible to investigate all the fields belonging to the infant's personal variables and environmental variables.

The purpose of this study is to analyze variables affecting parents' and elementary school students' value of computer science after creative computer science education, through multiple regression. Many researches on Informatics subject have focused on the effect of the subject contents on students but hardly dealt with parents' recognition. Thereupon, this study pays attention to the value of computer science recognized by parents and analyzes variables substantially affecting value variables of computer science related to parents' support for learning Informatics subjects. This paper did not verify the difference in recognition of parents and students but calculated more concrete influence by conducing multiple regression on the variables affecting the value recognized by each group. This is one of the reasons why this study is meaningful. According to the result of the analysis, variables affecting the value of parents on computer science the most are interest and satisfaction, and in students' case, self-efficacy is the variable affecting the value of computer science the most.
