The purpose of this study was to develop design guidelines on the learning analytics which can help to promote students' self-regulated learning (SRL) strategies in MOOCs learning environments. First of all, to develop the first draft of design guidelines, relevant literature review and case analysis on current MOOCs platforms such as edX, K-MOOC, Coursera, Khan Academy and FutureLearn were conducted. Then, to validate the design guidelines, expert reviews (validation questionnaires and in-depth interviews) and learner evaluation (in-depth interviews) were conducted. Through the recursive validation, the design guidelines were finalized. Overall, the final version of design guidelines on learning analytics to facilitate SRL strategies was suggested. The final design guidelines consist of 15 items in 10 categories related to the information analyzed based on individual student's learning behaviors and activities on MOOCs environments. Moreover, the results of interview also revealed that the social comparisons, learning progress reports, and personalization might contribute to the improvements of their SRL competences. This study has an implication that MOOCs could offer a higher success or completion rate to students with low SRL skills by taking advantage of the information on learning analytics

The purpose of this study is find the relation between students' concept and types of proof construction. For this, four undergraduate students majored in mathematics education were evaluated to examine how they understand mathematical concepts and apply their concepts to their proving. Investigating students' proof with their concepts would be important to find implications for how students have to understand formal concepts to success in proving. The participants' proof productions were classified into syntactic proof productions and semantic proof productions. By comparing syntactic provers and semantic provers, we could reveal that the approaches to find idea for proof were different for two groups. The syntactic provers utilized procedural knowledges which had been accumulated from their proving experiences. On the other hand, the semantic provers made use of their concept images to understand why the given statements were true and to get a key idea for proof during this process. The distinctions of approaches to proving between two groups were related to students' concepts. Both two types of provers had accurate formal concepts. But the syntactic provers also knew how they applied formal concepts in proving. On the other hand, the semantic provers had concept images which contained the details and meaning of formal concept well. So they were able to use their concept images to get an idea of proving and to express their idea in formal mathematical language. This study leads us to two suggestions for helping students prove. First, undergraduate students should develop their concept images which contain meanings and details of formal concepts in order to produce a meaningful proof. Second, formal concepts with procedural knowledge could be essential to develop informal reasoning into mathematical proof.

The goal of this study was to apply an expectancy-value model(Wigfield & Eccles, 2000) to explain changes in six multi-ethnic students' achievement motivation in mathematics during sixth (2012) to eighth (2014) grades. In order to achieve this goal, we used narrative research methods. Although individual students' achievement motivation and mathematics related life experiences differed, there are some common factors influencing their motivation development, especially (a) roles played by parents and teachers; (b) assessment of peers' competencies; (c) past learning experiences related to mathematics curriculum; (d) perception of the relationship between mathematics competency and other subjects; (e) home backgrounds; and (f) perceived task values. In this study, we achieved some insight into why some multi-ethnic students are willing to study hard to get good scores while others are uninterested in mathematics, and why some multi-ethnic students are likely to pursue new mathematical tasks and persist despite challenges, while others easily give up studying mathematics in the face of adversity. We argue that in order to increase and sustain multi-ethnic students' achievement motivation, educators and parents should recognize that motivation is contextually formulated in the intersection of current people, time, and space, not a personal entity formed in an individual's mind. The findings of this study shed light on the development of achievement motivation and can inform efforts to develop multi-ethnic students' positive motivation, which might influence their mathematics achievement and success in school.

For teaching division-with-remainder(DWR) problems, it is necessary to know students' strategies and errors about DWR problems. The purpose of this study is to investigate and analyze students' strategies and errors of DWR problems and to make some meaningful suggestions for teaching various methods of solving DWR problems. We constructed a test which consists of fifteen DWR problems to investigate students' solving strategies and errors. These problems include mathematical as well as syntactic structures. To apply this test, we selected 177 students from eight elementary schools in various districts of Seoul. The results were analyzed both qualitatively and quantitatively. The sixth graders' strategies can be classified as follows : Single strategies, Multi strategies and Assistant strategies. They used Division(D) strategy, Multiplication(M) strategy, and Additive Approach(A) strategy as sub-strategies. We noticed that frequently used strategies do not coincide with strategies for their success. While students in middle group used Assistant strategies frequently, students in higher group used Single strategies frequently. The sixth graders' errors can be classified as follows : Formula error(F error), Calculation error(C error), Calculation Product error(P error) and Interpretation error(I error). In this study, there were 4 elements for syntaxes in problems : large number, location of divisor and dividend, divisor size, vocabularies. When students in lower group were solving the problems, F errors appeared most frequently. However, in case of higher group, I errors appeared most frequently. Based on these results, we made some didactical suggestions.

The purpose of this study is to compare and analyze the effects of the educational context variables on 8th-grade science achievement of 5 top performing countries(Korea, Singapore, Taiwan, Hong Kong and Japan) in TIMSS 2015. TIMSS 2015 science data and questionnaire results were used for fitting Hierarchical Linear Model (HLM) in this study. According to the results, such student-level variables as home resources for learning, students' interest in science learning, valuing science, Students' Educational Expectations gave significant influence on the science achievement of Korean students. School-level variables including Student Economic Background, and School Emphasis on Academic Success gave significant influence on the science achievement of Korean students. Comparing 5 countries, home resources for learning, students' interest in science learning, Students' Educational Expectations gave significant influence on the science achievement in all 5 countries. At the school level, Student Economic Background is statistically significant in explaining students' science achievement gap in all countries except Japan, and Teaching Limited by Student Needs gave significant influence on the science achievement in all countries except Korea. Discussed in the conclusion are ways to improve middle-school science teaching and learning including reducing the education divide among socioeconomic status, teaching innovation for competency education, inquiry and reinforcement of lab activities in science classes, and so on.

This study aims to analyze the correlation of creative personality, environment, process, and product as related to scientific creativity for different levels of elementary school students. We evaluated 105 fifth graders' responses to two tests: i) the scientific creativity test for creative process and product and ii) the self-report test for creative personality and environment. In the self-report test, creative personality comprises cognitive and affective personality, and creative environment constitutes home and school environments. To attain a deeper understanding of phenomena that cannot be explained by a quantitative analysis, interviews were conducted with four students who had the highest scores in creative product and four students who had the lowest scores in creative product while having higher-than-average scores in creative process. First, correlation of creative personality and environment were not significant. Second, in the interviews, students who had the highest scores in scientific creativity had common characteristics, namely, the ability to endure current difficulties to achieve future success and the propensity to listen to other people's ideas critically. Third, students who had the highest scores in creativity hailed from families that respected their opinions, whereas students with the lowest scores belonged to families that disregarded or neglected their opinions. Finally, this study specifies the criteria that should be considered for affective and environmental aspects of scientific creativity education.

This study begins with the interests of the problems in learning a region under the Korean National Curriculum in geography field and the perceptions on the region which affects students 'formation of regional concept. The purposes of this study are to find problems in learning a region and to construct a new content for learning a region to improve the current problems. This study suggests that it is necessary for student to establish a clear concept on a region in order to effectively learn a region. Therefore, this study reviews how concepts on a region have changed and selects important elements in learning a region by considering a level of students' understanding. The important elements selected in this study are the definition of a region, the formation of a region, and the system of a region. By learning a real region established as a 'region for instruction' of a medium scale, students can reach an appropriate level of meaningful understanding of a region. This study found that an appropriate selection of scale in choosing the extent of a region was critical in success of effective organization of learning contents.

This study investigated if there are differences between Korean and Chinese consumers among the determinants of consumer complaint intention, type of complaint intention, and traits of complaining behavior. Sample subjects used in this study were female college students in Jeollabukdo and Jeollanamdo, Korea and Yunnam, China. Questionnaire data from 780 college students(Korea: 441, China: 339) were analyzed through a reliability analysis, factor analysis, frequence, mean, and multiple regression analysis. The results of the study were as follows. First, complaint intention of college students was divided into 3 factors, voice, private, and third party. Second, the findings of regression analysis for the total sample showed that the determinants of the factor 'voice' were the country, salespeople, product involvement, complaint cost, psychological tension, and social benefit. Whereas, the determinants of the factor 'private' were the producer, product involvement, psychological tension, and social benefit. Also, the determinants of the factor 'third party' were the country, oneself, salespeople, complaint cost, personal norms, and social benefit. Third, significant differences were indicated in the determinants of the 'voice', 'private' and 'third party' factors of complaint intention between Korean and Chinese consumers. Fourth, the complaint intention factors of 'voice' and 'third party' of Chinese consumers were higher than Korean consumers. Fifth, the attributions to dissatisfaction of Korean consumers were higher than Chinese consumers, and the product involvement, possibility for success, and consumer complaint attitudes of Chinese consumers were revealed to be higher than Korean consumers.

This study reports the results of an exploratory investigation into building number technique applied by a sample of novice students using Electronic Dewey(ED). For control purposes, a second sample used the same classification schedule but in print format. In this experiment, the DDC 20 in print had a higher success rate than ED. While the searches in ED took shorter time than DDC in print, students using DDC 20 in print were able to build more correct numbers than ED. Novice users did not take full advantage of system features of ED. Therefore, it is important to note the overall difficulty with which users could build numbers from the ED after little training. However, it is interesting to note that the students in the CD-ROM group were more interested in building numbers than their colleagues in the Print group. The correlation between the grade of English course and the score in experiment was negative in Print group. And the correlation between GPA and the score in experiment was a little positive. The correlation between the time and the score in experiment was quitenegative.
