The effects of computer-assisted instruction (CAl) using molecular-level animation upon students' conceptions, attitudes toward science instruction, and learning motivation were investigated. Treatment and control groups (2 classes) were selected from a girls middle school in Seoul, and taught about the motion of molecule for 5 class hours. Before instruction, the short-version Group Assessment of Logical Thinking (GALT) and the Patterns of Adaptive Survey were administered, and the grade for the previous science course was obtained. The GALT score was used as a blocking variable, and the others as covariates. After the instructions, the researcher-made conceptions test, the test of attitudes toward science instruction, and the motivation questionnaire were administered. The perception questionnaire of CAl was also administered to the treatment group. Although more students in the CAl group had sound understanding about the motion of molecule, the scores of the conceptions test for the two groups were not significantly different at .05 level of significance. The students in the CAl group, however, were found to have more positive attitudes toward science instruction and learning motivation. In the perception questionnaire of CAl, most students in the treatment group exhibited positive attitudes toward the CAl. However, some students mentioned that they were disturbed by noisy environments, and that they could not understand some content presented. Educational implications are discussed.

In order to do morally right behavior that we cognitively know, prosocial moral motivation is necessary. Previous studies revealed emotion is important for prosocial moral motivation. This was supported by cognitive neuroscience studies using functional magnetic resonance imaging(fMRI) in which the activity of ventral striatum(VS) was observed when people made moral decision. VS was originally known as the core area of reward process but recently VS was found to respond also to social reward and even feeling of prosocial emotion itself. However it is not clear why VS was activated when people experience prosocial moral sentiments. The aims of this review article were to find situations in which people are prosocially and morally motivated and to understand more about the role of emotion as a moral motivator by examining evidence regarding the neural network, including VS, of prosocial moral motivation and moral decision-making.

The purpose of this study was to verify the effect of elderly sports activities participation motivation on Leisure Satisfaction The participants were from elderly who the daily sports program. A total of 250 questionnaires were distributed from Sep. 1 to Oct. 31, 2018 and, after excluding 53 questionnaires that had missed or inappropriate answers thus low reliability, 197 questionnaires were included in effective sample. The collected data were analyzed using SPSS Statistics 21 and frequency analysis, exploratory factor analysis, reliability analysis, regression analysis were performed. The results, based on them, are as follows: First, Among the motivations for participating in the elderly sports activities, internal motivation influenced psychological satisfaction, educational satisfaction, psychological satisfaction. Second. external motive influenced social satisfaction, resting satisfaction. Third. amotivation influenced psychological satisfaction, educational satisfaction, resting satisfaction, environmental satisfaction.

This study investigated the effects of cooperative and individual computer-assisted instructions upon middle school students' science conceptions, achievement, perception of learning environment, and motivation. The cooperative, individual, and traditional learning groups were selected from a middle school, and taught about the motion of molecule for 5 class hours. Data analyses indicated that the students with cooperative computer-assisted instruction scored significantly higher than those with traditional instruction in the tests of conceptual understanding, perception of learning environment and motivation. Better understanding of the cooperative learning group was also found in a retention test of conceptions. In addition, there were significant interactions between the instruction and the level of prior achievement in the tests of retention of conceptions and motivation. Educational implications are discussed.

The purpose of this study is to examine the effects of flipped learning on science achievement, science interest, and intrinsic motivation in middle school science course. In order to achieve the purpose of this study, data was collected from 90 7th graders who were assigned to the experimental group(flipped learning class) or comparison group(lecture class) in Seoul. After collecting data, we examined mean difference between teaching method using ANCOVA. The results of this study were as follows: The flipped learning is associated with significant improvements in science achievement and science interest. However, the flipped learning is not associated with significant improvements in intrinsic motivation. This study was investigated effects of the flipped learning and expanded the understanding of the flipped learning.
