Interest has been studied as one of the construct to understand and improve learning in science. While informal science education is getting increasing attention as science education has been extended from formal school science to informal science learning including after-school program or science museum activity, however, little has been studied in comparing to the needs. In this study the authors investigated students' interest about learning science in the context of informal science education. For this the survey tool in the article of Im and Pak (2000) was utilized through modification, and 155 elementary students' responses were analyzed with factor analysis and basic statistics. The factor analysis showed that the students' interest about learning science in the context of informal science education has multi dimensions like subject, motivation, and activity dimension. The result showed that students' interest decreased as their grade is higher, and that the interest of intrinsic motivation, empirical activity, and descriptive subject were relatively high while the interest of extrinsic motivation, cognitive activity, and specific subjects were low. From this study the authors could infer the necessity of instructional strategy in consideration of students' interest for more effective science learning in informal science education environment.

This study examines the activity system of teaching and learning about informal statistical inference using sampling simulation, based on cultural-historical activity theory. The research explores what contradictions arise in the activity system and how the system changes as a result of these contradictions. The participants were 20 elementary school students in the 5th to 6th grades who received classes on informal statistical inference using sampling simulations. Thematic analysis was used to analyze the data. The findings show that a contradiction emerged between the rule and the object, as well as between the mediating artifact and the object. It was confirmed that visualization of empirical sampling distribution was introduced as a new artifact while resolving these contradictions. In addition, contradictions arose between the subject and the rule and between the rule and the mediating artifact. It was confirmed that an algorithm to calculate the mean of the sample means was introduced as a new rule while resolving these contradictions.

The purpose of this study was to research and analyze students' informal knowledge before they learned formal knowledge about fraction concepts and to see how to apply this informal knowledge to teach fraction concepts. According to this purpose, research questions were follows. 1) What is the students' informal knowledge about dividing into equal parts, the equivalent fraction, and comparing size of fractions among important and primary concepts of fraction? 2) What are the contents to can lead bad concepts among students' informal knowledge? 3) How will students' informal knowledge be used when teachers give lessons in fraction concepts? To perform this study, I asked interview questions that constructed a form of drawing expression, a form of story telling, and a form of activity with figure. The interview questions included questions related to dividing into equal parts, the equivalent fraction, and comparing size of fractions. The conclusions are as follows: First, when students before they learned formal knowledge about fraction concepts solve the problem, they use the informal knowledge. And a form of informal knowledge is vary various. Second, among students' informal knowledge related to important and primary concepts of fraction, there are contents to lead bad concepts. Third, it is necessary to use students' various informal knowledge to instruct fraction concepts so that students can understand clearly about fraction concepts.

This study aims to identify and categorize the content and public use patterns of social scientists' informal communication activities. Using Twitter data, we identified Korean 736 social scientists who participated in communication activities with the public, and analyzed 4,548 tweets that revealed their informal communication activities. This study is meaningful in that it explored informal communication between social scientists and the public, which was not previously revealed in scholarly communication, and identified the types of informal communication activities, communication media, and collaborative sectors in detail.

The purpose of this study was to explore the effects of perceived care-related burden and social support on life satisfaction and the moderating effect of social support from elderly spouses caring for their elderly partners with dementia. The subjects were 165 spouses aged over 60 years, caring for their elderly partners afflicted with dementia, and living in Seoul and Gyeonggi Province. The analysis results are as follows: First, the quantified total care-related burden shouldered by the participant spouses was 3.76 points (SD = .57), which was slightly higher than the median value. In the case of social support, informal support was scored 2.65 (SD = .78), and formal support was scored 2.60 (SD = .77), which was lower than the median value. Life satisfaction earned a score of 3.11 points (SD = .78), which somewhat exceeded the median. Second, subjective health status, income level, burden from social activity, and informal support influenced life satisfaction. Put differently, the higher the subjective health status of a caring spouse, the higher the income level, the lower the social activity burden, the stronger the informal support, and the greater the life satisfaction. Third, the interaction terms of social activity burden and informal support were significant. Therefore, informal support had a moderating effect on the relationship between social activity burden and life satisfaction among the elderly with dementia. In other words, even though the caring spouses experienced a burden from social activities, the higher the frequency with which they accessed informal support, the lower the decrease in life satisfaction.

The purpose of this study is to investigate the reasons and backgrounds of drawing auxiliary lines in the proof of geometry. In most of proofs in geometry, drawing auxiliary lines provide important clues, thus they play a key role in deductive proof. However, many student tend to have difficulties of drawing auxiliary lines because there seems to be no general rule to produce auxiliary lines. To alleviate such difficulties, informal activities need to be encouraged prior to draw auxiliary lines in rigorous deductive proof. Informal activities are considered to be contrasting to deductive proof, but at the same time they are connected to deductive proof because each in formal activity can be mathematically represented. For example, the informal activities such as fliping and superimposing can be mathematically translated into bisecting line and congruence. To elaborate this idea, some examples from the middle school mathematics were chosen to corroborate the relation between informal activities and deductive proof. This attempt could be a stepping stone to the discussion of how to teach auxiliary lines and deductive reasoning.

Recent studies say that informal learning is influential to students as much as formal teaming. Nowadays we can see various informal teaming inside and outside of the country. In 2004, it was the first attempt in Korea that engineer had gone to the elementary school fur activity that included scientific experiment and engineering work with students. National Academy of Engineering of Korea (NAEK) progressed activity with companies and elementary schools for students' making sense of engineer and what they are doing. To do that, NAEK had developed the network that company could support its local school's science education circumstance by engineers' visiting program. In 2004, seventeen companies including both large and small ones took part in the program called' Korea Junior Engineering Achievement (KJEA)'. In this program, engineers played the role of teacher (we call them company teacher), elementary school teachers played the role of organizing classes as a mediator. Elementary school teachers and company teachers' recognition is very important to make students' activity meaningful. The aim of this study was to give implication for informal science education activity for which engineers visit their local school. We got the result by survey and interview of company teachers and elementary school teachers. This study's result shows that almost company teachers and school teachers were in favor of purpose of this informal science education activity and satisfied with their participation. But some company teachers were not satisfied with worksheets, materials provided and relationship between school and company). Elementary school teachers and company teachers, both of them believed students' program as the key factor of success of informal science education activity. To make informal science education grow, school administrator and teacher need to have a will to utilize the activities more actively.

The export regulation of semiconductor core materials, which began with the recent revision of the export management regulations of Japan, raises the need for a new cooperation network. A hierarchical management network that was effective in the fast-follower system requires organic cooperation between the public sector and industry through a multilateral network that emphasizes horizontal co-operation among innovation actors. This study focused on the relational capital that exists among members of a business association such as an association that has been relatively marginalized from previous studies. In addition, this study aimed to analyze the effect of network activity characteristics such as industry-university linkage and informal exchange on technological innovation. Through this, I would like to draw implications for enhancing the effectiveness of the government's R & D support and innovation performance of R & D companies. Based on the results of the SMEs R & D survey, this study found that relational capital, informal exchange had a positive effect on technological innovation performance. However, if the relational capital exceeds a certain level, it is analyzed that there is a negative effect due to group think and lock-in effect. This means that informal exchange channels should be expanded for innovation and enhancement, and relational capital should be managed in consideration of the negative effects that may occur when certain levels are exceeded.
