  • The student group division is benefit for universities to do the student management based on the group profile. With the widespread use of student smart cards on campus, especially where students living in campus residence halls, students' daily activities on campus are recorded with information such as smart card swiping time and location. Therefore, it is feasible to depict the students with the daily activity data and accordingly group students based on objective measuring from their campus behavior with some regular student attributions collected in the management system. However, it is challenge in feature representation due to diverse forms of the student data. To effectively and comprehensively represent students' behaviors for further student group division, we proposed to adopt activity data from student smart cards and student attributes as input data with taking account of activity and attribution relationship types from different perspective. Specially, we propose a novel student group division method based on a multi-view student attribute heterogeneous information network (MSA-HIN). The network nodes in our proposed MSA-HIN represent students with their multi-dimensional attribute information. Meanwhile, the edges are constructed to characterize student different relationships, such as co-major, co-occurrence, and co-borrowing books. Based on the MSA-HIN, embedded representations of students are learned and a deep graph cluster algorithm is applied to divide students into groups. Comparative experiments have been done on a real-life campus dataset collected from a university. The experimental results demonstrate that our method can effectively reveal the variability of student attributes and relationships and accordingly achieves the best clustering results for group division.

  • The Engineering school of Tohoku University has been offering a Team-based Engineering Design Course to its first year students since 1996 in order to increase the level of both motivation and interest in engineering. Freshmen are required to select one of approximately 150 topics and do some research on this topic. This course also provides opportunities for students to participate in exchange programs with the University of Washington (UW) and the University of Science and Technology Beijing (USTB). In the Tohoku-UW exchange program, which began in 1999, between 10 and 25 students of Tohoku visit the UW annually to present the results of the subjects the school has appointed in advance in the Team-based Engineering Design Course. In the Tohoku-USTB exchange program, which began in 2007, about 15 students from each university participate in a one day meeting organized by the students themselves. They give a presentation on either the results of the subject they selected in the course, or on an engineering related topic both groups have agreed to in advance. In this paper, a detailed history, the objectives, a schedule and the budget in these unique exchange programs is introduced together with an outline of the course and its contribution to the engineering design education.

  • University teachers of linear algebra often feel annoyed and disarmed when faced with the inability of their students to cope with concepts that they consider to be very simple. Usually, they lay the blame on the impossibility for the students to use geometrical intuition or the lack of practice in basic logic and set theory. J.-L. Dorier [(2002): Teaching Linear Algebra at University. In: T. Li (Ed.), Proceedings of the International Congress of Mathematicians (Beijing: August 20-28, 2002), Vol. III: Invited Lectures (pp. 875-884). Beijing: Higher Education Press] mentioned that the situation could not be improved substantially with the teaching of Cartesian geometry or/and logic and set theory prior to the linear algebra. In East Asian countries, science-orientated mathematics curricula of the high schools consist of calculus with many other materials. To understand differential and integral calculus efficiently or for other reasons, students have to learn a lot of content (and concepts) in linear algebra, such as ordered pairs, n-tuple numbers, planar and spatial coordinates, vectors, polynomials, matrices, etc., from an early age. The content of linear algebra is spread out from grades 7 to 12. When the high school teachers teach the content of linear algebra, however, they do not concern much about the concepts of content. With small effort, teachers can help the students to build concepts of vocabularies and languages of linear algebra.

  • The roles-grafting research is an approach to educational studies intended to graft five roles of supervisors, graduate students, teachers, principals and administrators. The approach is divided into four chained and cyclical aspects: drafting research blueprint, revising research blueprint, executing research blueprint and assessing performances. The approach maintains five basic principles: principles of inheritance, innovation, practicality, scientific basis and grafting. It is a paradigm of innovative research that has been developed in China that is worth a thorough investigation and extensive analysis.

  • The purpose of the study is to report differences in the effects of learner characteristics on the self-regulated learning (SRL) abilities between Chinese and Korean distance learners by using a structured SRL scale. A standardized 54-item self-regulated learning scale (SRAS) was used. The reliability was tested both in China and Korea which showed the scale had good reliability. The comparative study were conducted by administering the SRAS on 1999 Chinese distance learners from the Open Distance Education Center of Beijing Normal University and 1941 Korean distance learners from H Cyber University. Data on four dimensions of SRL - planning, control, regulating, and evaluation - were analyzed using 't-test' and 'ANOVA' with regards to the learner characteristics such as gender, age, prior education level, semesters, location and major. Results indicated that the average participant had an above medium level of SRL ability in all of the four dimensions. There were significant differences in the self-regulated learning ability between Chinese and Korean distance learners. Chinese distance learners scored higher in SRAS than Korean distance learners. The effects of learner characteristics on the SRL ability showed different patterns in the two countries. As for gender, male learners scored better in SRL than female learners in China, whereas it was just the opposite in Korea. No age differences were found in China, but Korean data exhibited a consistent age effect in all dimensions. In Korea, the age group older than 46 scored the highest, followed by the group between 35 to 45 years old, the group between 26 to 35 years old and the group younger than 25. As for location, Korean distance students from metropolitan were better than those from other regions, whereas it was on the contrary in China, albeit the location effect was not statistically significant. Prior education level had a clear and consistent effect on the SRL ability in both countries: the distance learners from junior colleges had better planning, regulating and evaluating abilities than those who came from senior high schools. These results have been discussed in various contexts of distance/online education as well as in relation to different culture between China and Korea. The results will also have implications for designing distance and online learning generally.

  • Purpose: This study was done to examine the level of performance and predictors influencing health promotion behavior of Korean students in China. Method: The participants were 160 Korean students who have lived in Beijing, China. Data were collected by self reporting questionnaire from september to november, 2001 and t-test, ANOVA, Person's correlation coefficients, and stepwise multiple regression were used to analyze the data. Results: The health promotion behavior score showed a positive correlation with perceived health status(r=.17, p=.025), social support(r=.29, p=.0001), and self-efficacy(r=.41, p=.0001). By use of stepwise multiple regression analysis, it was determined that the main factors influencing health promotion behavior were self-efficacy 17.0%(F=32.56, p=.0001) and social support 2.2%(F=4.11, p=.044). These variables explained 19.2% of the variance in the health promotion behavior scores. Conclusion: Self-efficacy and social support were the main factors influencing health promotion behavior. These findings showed that we need to develop nursing strategies to promote self-efficacy and social support for Korean students in China.

  • Inquiry activity is a major source of student investigation which both of the national curriculum standards strongly emphasize for achieving scientific literacy. The purpose of this study was to examine inquiry activities incorporated in high school biology textbooks used in China and Korea. The inquiry activities were examined with regard to inquiry level and science process skills. Bell's and a modification of Padilla's framework were used in these analyses. Results show that the Korean textbooks were more exclusively occupied by simple inquiry activities - None of them provided activity more complex than level 2 inquiry. In addition, the Korean textbooks had uniformly basic science process skills, whereas their Chinese counterparts gave students some challenges for higher level process skills. Therefore, it cannot be guaranteed that the activities in the Korean textbooks are helpful in guiding students toward a gradual progression to high-level inquiry. Implications for inquiry-based science education were suggested based on the results of the study.
