The purpose of this study was to investigate perception of primary school teachers about operation of after-school computer class. Research questions were set up as follows: First, what type is preferred on the operation type for after-school computer class? Second, what is the perception about the adequacy of contents for after-school computer class? Third, what is the perception about instructors' expertise? Fourth, what is the perception about the effects of after-school computer class? Finally, what is the perception about facilities/ equipment and evaluation system of after-school computer class? To figure out these questions, this study conducted literature review and questionnaire survey. The results of this study are as follows: First, approximately 82% of respondents preferred to have after-school computer class operated by outsourced agency. Second, overall, the perceptions about the operation of after-school computer class were positive: The adequacy of contents, instructors' expertise, the effects, facilities/ equipment and evaluation system are seen as mostly positive. Third, its differences between school self-operated computer class and private sector computer class were insignificant. Fourth, its differences among various sizes of the school were significant. The implementaion of after-school computer class was considered as more positive in small schools. Finally, researchers suggested that it was necessary to develop an plan considering school sizes for more efficient implementation of after-school computer class.

The purpose of this study was to explore the effect of 8 weeks after school classes of track sports on students' start motion through kinematic variables. 30 students in D National university of education participated for this study. These students divided into two groups, 17 students for experimental group and 13 students for control group. The two groups participated in general athletic class as common class, and the experimental group participated in after school class additionally. The general class taught track and jump skill for 3 hours a week, and the after school class taught only athletic running skill for 30 minutes a week. Pre and post test assessed to assess students' kinematic changes. Findings indicated that velocity and step rate were increased, and contact time, step length, displacement of center of mass were decreased in the experimental group. In the control group, early velocity, knee/hip angle velocity were increased, and contact time, step length, displacement of center of mass were decreased. In conclusion, the students who only participated in general class, could not maintain athletic skills obtained from the class. However, students who participated in both general and after school class accomplish athletic start skill. This is because Continuous learning effect helped students keep the skill and did not lose the skill. Thus, in order for students to learn specific sport skills, joining after school class with general class together is recommended.

The purpose of this study is to find out the actual status of the math after-school program in the elementary school and the content of the program. We survey the 115 math external math lecturers of the 100 elementary schools in Busan and analyze the results. Research questions are set as follows. 1. What is the status of the elementary math after-school? 2. How is the content of the program of the elementary math after-school? The results of the survey are analyzed as follows. First, any of the external math after-school lecturer did not major in math education and 87% of them majored in another discipline. Second, 47% of the external math after-school lecturers are employed by privately-held companies. Third, 64.4% of the content of the after-school programs is the supplement and deepening of the regular math class. Fourth, 76.5% of the time of the first class of the math after-school program is 50 minutes and 46% of the math after-school opens 5 classes per a week. Fifth, most programs consist of the problem-solving style class. Sixth, it is difficult to run the math after-school according to students' level and grade. Based on the above discussion, I suggest the following. First, math after-school class should be the action-oriented class to motivate the positive and interested participation of the students. Second, lecturer training and various math class programs is required to improve the quality of the math after-school class.

The purpose of this paper was to investigate differences in middle school student's after school satisfaction according to the type and the degree of flow of after school. For the purpose of this paper, a survey was conducted including a questionnaire consisting of a general characteristic of the study object, a general characteristic of the after school class, learning-flow scale, and after school satisfaction scale. The subjects were 382 students who were selected at random from middle school students. Cronbach' ${\alpha}$ and MANOVA were employed for data analysis. The results were as follows: First, the students with special-ability aptitude class were more satisfied for after school instructors than the students with subject class. Second, the students with the degree of high learning-flow showed higher satisfaction in after school class curriculum, instructors, and educational facility than the degree of low learning-flow students. Third, among the students who were high in learning-flow, the students with special-ability aptitude class were more satisfied with after-school class curriculum and educational facility compared to the students with subject class.

The purpose of this research is to suggest some measures to improve policy issues by analyzing policy related to a child care service program in the community. Gilbert and Terrell's social policy analysis framework is used to analyze an after-school care service program for elementary school children. Furthermore, the Elementary Care Class(including the After-school Program), Youth After-school Academy, and Community Child Center, referred to as public care services, are employed to analyze community care service programs for children. The Elementary Care Class, Youth After-school Academy and Community Child Center are very similar in terms of the contents and application of the care service program for children, and mainly serve children in low-income groups. In addition, although user overlapping is an inevitable problem because the operating time of the Elementary Care Class and After-school Program coincides with that of the Youth After-school Academy and Community Child Center, it is structurally very hard to adjust the content of service, operating time, and so on because of differences in the delivery system for each program. Therefore, it is necessary to generate a unified delivery system to manage after-school care service programs for children and create a new special control tower to solve these problems. Furthermore, it is needed to extend the services to children from general double-income family, which is a blind spot of the care service.

This study aims to investigate the awareness and policy demands of after school care classes of mothers with elementary school children. The participants of study were 25 mothers with elementary school children in Seoul, Gyeonggi, Incheon, Gangwon. Data collection was conducted from June 23, 2017 to July 18, 2017 by focus group interview. Through the data analysis, the results of the study were analyzed as 'the reality of the after school care class that the mother sees' and 'the policy demands of the mother's after school care class'. 'The reality of the after school care class that the mother sees' is 'the overall level of after school care class is low', 'the probability of selecting the same as a lottery', 'the quality of education that varies depending on the level of the teacher', 'for the child attending the care class negative awareness'. 'Mother's policy demands for after school care classes' are presented as 'positioning as a substitute for thinking and caring', 'improvement of separation between parents' expectations', 'expansion of care recipients', 'request for resilient management'. As the conclusion of this study, first, after school care classes need to focus on the care function. Second, it is necessary to operate after school care classes by level. Third, the realistic needs of mothers should be reflected so that after school care classes can be positioned as alternatives to private education.

Two (second-grade) classes of Yu-song middle school were chosen to research the effect of the visualization in the learning of probability calculation at a middle school. One class, as an experiment class, was taught the probability calculation of probability unit by the visualization learning and the other, as a controlled class, was taught it by the traditional lecture, and then through the writing tests there was a verification on the effect of right after test and the delaying test after 3 weeks to examine the learning effect of high- and low-level groups. It was difficult for the students to visualize the problems of the probability calculation, but I suggested simple models to the students and helped them to learn meaningfully. As a result of this study, there showed statistically significant difference in high-level group in the right after test.(P< .05) In the delaying test after 3 weeks, there also showed statistically significant marks only in high-level group.(P< .05) The visualization in the learning of probability calculation took more affirmative effect in the experiment class than the comparative class only in high-level group. The students in low-level group has difficulties in the visualization activities, but all the students in high-and low-level group thought the visualization was a great help to them in learning probability calculation.

In this paper, we discuss how to assess students' understanding of concepts during class, after class and in regular exams in the mathematics classes using the handheld graphing technology. We show some methods of assessment that are compatible with the class using the handheld graphing technology. These methods are adjustable to students' learning during class, homework after class or in regular exams. As a feedback of these methods we give students additional opportunity to understand concepts by giving additional concept provoking problems or giving additional help if necessary.
