The programming(algorithm) automated assessment system is to evaluate automatically the accuracy and time/space efficiency of user's solution to the problem which is provided. This system gives the immediate feedback of the solution, real-time ranking. So, in the course of data structure and algorithm, we can apply the knowledge which we have learned to the problem solving. Especially, in the basic course of learning the syntax of the programming language, the novice student can learn in easy and fun by solving the simple problem. The university students can understand in the easy way the meaning of asymptotic analysis of algorithm in data structure & algorithm course.

This research aims to build a concept map reflecting gifted elementary students' perception on fun factors of the classes for the gifted. Data for this research was gathered through brainstorming of 80 students currently attending classes for the gifted. 10 of them were selected as focus group for classification and evaluation, and 140 gifted-class students were asked of the fun factors for level of agreement after concept map analysis. Results of the research were, first, 46 final statements about fun factors which are categorized into 6 sub-categories ('the gifted class teacher's encouragement and feedback', 'confidence and chance', 'teamwork and intimacy with gifted friends', 'fulfilling, beneficial, and rewarding feeling', 'new and special experiments', 'qualitatively different class level and learning environment'). Second, the gifted students showed highest level of agreement on 'new and special experiments' category among the 6 sub-categories. Implication of this research on the field has been discussed.

The purpose of this research was to investigate how the peer review activity of lab report in the problem-solving experiment effected on the description ability and the quality improvement. The students who were taking the general chemistry experiment course were the subjects for this study. They finished lab reports and received peer review from their peers more than two times. The students who got feedback answered on peer review, revised their reports, and subsequently, completed final reports. The result showed that peer review affected the qualitative improvement of the lab report, specially in the process of 'designing experiment' and 'drawing conclusion and evaluation'. Students could organize their thoughts through writing lab reports. During this process, peer review activities provided the opportunity of self-examination and the way for viewing as objective standpoint. Moreover, the activities established communication fields for exchanging mutual opinions and learning.

Objectives : Integrative medicine in Korea is the 21st century-style medical practice of two orthodox medical doctrines, traditional Korean medicine and western conventional medicine, as well as complementary and alternative medicine (CAM). CAM with scientific evidence should be incorporated in undergraduate curricula for the purpose of Korean integrative medicine. Methods : Items of detailed objectives, syllabi, textbooks, instructor's experiences, and effectiveness and reason for difficulty of the CAM curriculum for undergraduate students were analyzed and the preference of CAM therapies and others were also evaluated. Results and Discussion : The effectiveness of this CAM class curriculum was high (8.0$\pm$1.4) enough to be used in other Oriental medical colleges. Development of ability for self-study was rated as 7.0$\pm$1.7 and the helpfulness for clinical use was marked as 6.8$\pm$1.9. Students preferred placebo, Ayurveda, aromatherapy, yoga, functional food, bio-feedback and homeopathy. The difficulty degree was 7.2$\pm$1.6, and the amount of content was suggested as the major reason for it. We also found that this curriculum can be a model for self-oriented study and problem-based learning. Discussions were made for the improvement of the implemented CAM curriculum, which was shown to be very effective for the achievement of Korean integrative medicine. Conclusion : We have successfully installed a CAM curriculum for undergraduate students at the College of Oriental Medicine, and it can be used in others.

CRESST(the National Center for Research on Evaluation, Standards, and Student Testing at UCLA) is now carrying out the research, which was scheduled for a five year period from 2007 to 2011. This research aimed at testing the effectiveness of the formative assessment program by continuously conducting the program on the target group and steadily applying the recurring feedback, in order to reform the teachers' teaching and to facilitate students' learning. To do this, CRESST has set out to develop the material for 7th graders since January 2007, and KICE(Korea Institute of Curriculum and Evaluation) have been running a collaborated research since July 2007, while sharing the instructional materials developed by CRESST. In 2008, the pre-test was conducted prior to this study in 2009. Especially, this paper deals with the Korean 7th graders' scholastic achievements in algebra domain measured by PowerSource(c). In addition, this study would examine the responses of teachers and students on its application.

In this study, we conducted eight reciprocal peer tutoring classes where each student took either role of a tutor or a tutee to study covariational reasoning in ninth graders. Students were given the opportunity to teach their peers with their covariational reasoning as tutors, and at the same time to learn covariational reasoning as tutees. A heterogeneous group was formed so that scaffolding could be provided in the teaching and learning process. A total of eight reciprocal peer tutoring worksheets were collected: four quantitative graph type questions and four questions of the qualitative graph to the group. The results of the analysis are as follows. In reciprocal peer tutoring, students who experienced a higher level of covariational reasoning than their covariational reasoning level showed an improvement in covariational reasoning levels. In addition, students enhanced the completeness of reasoning by modifying or supplementing their own covariational reasoning. Minimal teacher intervention or high-level peer mediation seems to be needed for providing feedback on problem-solving results.

In this paper, we compare and analyze smart technologies and present six obstacle detection features to help visually impaired people walk. Traditionally, visually impaired people walk with the white cane or a guide dog. With the development of IoT technology, various smart walking aids systems have been developed. Those intelligent walking aids systems have obstacle-detecting systems and route-guidance systems. Many researchers are developing the walking aids system, which detects an obstacle and provides the obstacle information by haptic feedback. Also, they are designing the database server system to share the obstacle information. Particularly the composed system can quickly give an obstacle-avoidance route using shared obstacle information. Smart walking aids systems for visually impaired people will advance more rapidly by applying machine learning and intelligent systems.

The purpose of this study is to search the effective teaching-learning program by considering how affect on formation of linear function using Excel. This study was based on qualitative case study. The teaching experiment using Excel executed with five 8th graders' students for second research content. Teaching experiment was performed for two classes. Collecting the data was conducted via observations and interviews with students. The data include audio and video recording of the students' work, students' worksheets and detailed field notes. The conclusions drawn from teaching experiment are as follows: First, when students explored relevancy content of function in Excel environment, formation of concept of function was facilitated by experiencing operation of algebraic formulas, tables and graphs. We could infer that formation of concept was effected by conjecture activity and iterative process of feedback through Excel environment. Second, the students explored the changes very interestingly making algebraic formulas and presenting tables and graphs. The students were familiarized with observation on algebraic formulas, graphs and tables concurrently. Also, they tried to look for general rules through inductive observation. According to this study, we noticed that exploration teaming environment using Excel could supplement paper-and-pencil environment.
