A cooperative teaming has been taken to consolidate the autonomous motivation of students and to develop a desirable attitude in a mutual cooperative atmosphere. Some studies on the reward effect showed that the reward after the evaluation, in the processes of cooperative learning, worked on students' learning motive directly, and the group reward was effective in learning attitude and the individual reward in academic achievement, respectively. Assuming that the group reward and the individual reward are organized and applied as a complex reward, the effects of rewards will appear, this study examined the effect of the complex reward on academic achievement and teaming attitude. For this study. 2 classes were randomly selected out of a elementary school in Gwangju and the teaming unit was based on chapter 4「The structure and function of plants」 in the 5-1 elementary Science textbook. This research has been done for 4 weeks after the students learned STAD for 8 weeks previously. The learning attitude was examined in pre and post tests, and the academic achievement was inspected twice at 2-week intervals after the pre test. The results were analysized by the SAS program In the case of academic achievement, both groups showed a significant improvement(p<.05). The experimental group showed no significant improvement in the first test, compared with the control group(p>.05), but after 4 weeks, it showed a significant improvement in the second test, compared with the control group(p<.05). From this result, it is identified that the reward should be done for a long time and the individual reward of the complex reward is successful in improving academic achievement. However, in the case of learning attitude, there was no meaningful difference in both groups(p>.05). But the control group showed a significant improvement, compared with the experimental group(p<.05). According to this result, it is indicated that the group reward only is more effective in improving learning attitude and complex reward can decrease the individual competition in experimental group.

Adaptive resonance theory (ART2) characterized by its built-in mechanism of handling the stability-plasticity switching and by the adaptive learning without forgetting informations learned in the past, is based on an unsupervised template matching. We propose an improved tow-stage learning algorithm for aRT2: the original unsupervised learning followed by a new supervised learning. Each of the output nodes, after the unsupervised learning, is labeled according to the category informations to reinforce the template pattern associated with the target output node belonging to the same category some dominant classes from exhausting a finite number of template patterns in ART2 inefficiently. Experimental results on a set of 2545 FLIR images show that the ART2 trained by the two-stage learning algorithm yields better accuracy than the original ART2, regardless of th esize of the network and the methods of evaluating the accuracy. This improvement shows the effectiveness of the two-stage learning process.

The purpose of this study was to examine the effects of self-regulated learning program on the underachiever's academic achievement and academic self-concept. To achieve the purpose of study the research hypotheses were as follows : Hypothesis 1 : There will be significant differences in the improvement of academic achievement between the experimental group and the control group. Hypothesis 2 : There will be significant differences in the improvement of academic self-concept between the experimental group and the control group. To verify these hypotheses, 32 underachievers were selected from sixth grade students of 'D' elementary school located in Seoul. 16 students were allocated to the experimental group and 16 students were allocated to the control group. The experimental group trained with self-regulated learning program for 10 times(The length of each section was 60 minutes). The self-regulated learning program in this study was based on program by Kim. Yong-Soo(1998), The measurement instruments of the study were mathematics achievement test paper and academic self-concept test. To find out the difference, Pretest-posttest control design was used. Mean and standard deviations obtained from these tests were analysed with t-test. The major findings obtained through this study are as follows : First, self-regulated learning program was effective in improvement of academic achievement (p<.05). Second, self-regulated learning Program was not effective in improvement of academic self-concept. However, the experimental group showed significant improvement(p<.01) at academic self-concept and sub academic self-concepts (ability, achievement) in the data of pre-post test. it can be suggested that this program had positive influence on underachievers. Although it has some limitations, self-regulated learning program is effective to academic achievement and academic self-concept of underachievers, even though not significant, it has a positive t.

Due to the decrease in the school-age population, the number of freshmen at local college who lack basic learning skills is increasing. Thus, C college has been running a basic learning ability improvement clinic program. This paper is a case study that investigates the effect of basic learning ability improvement clinic programs on major class immersion, efficacy, and major class satisfaction. In 2022, a total of 459 students were surveyed, including 238 students who participated in online and offline classes for basic learning ability improvement clinics and 221 students who did not participate in classes. Data processing was performed using SPSS Ver. 26.0 was used. The results of this study are as follows. First, among the sub-factors of academic self-efficacy, the group participating in the basic learning ability improvement clinic showed significant differences in task difficulty preference and confidence. Second, the class participation group showed a significant difference in learning immersion in major classes. Third, the class participation group showed significant differences in all sub-factors of major satisfaction. In conclusion, it was found that the basic learning ability improvement clinic class had a significant effect on academic self-efficacy, learning immersion, and major satisfaction.

This paper proposes and evaluates empirically a new recommendation method in order to improve the learning achievement of learners using case-based method. In this paper, we first carried out a survey targeting teachers who work currently in Gyeongbuk area, and constructed learning cases depending on critical factors of learning. We next recommended differentiated learning methods to learners classifying according to learning cases by achievement level through this survey. The students of a middle school took part in the experiment in order to evaluate empirically the proposed learning cases. The students were divided into three groups by their achievement level and three separate learning cases were applied to each group. The weights among learning improvement elements applying to each group were added through the survey result of teachers. The experiment using the proposed case-based recommendation method showed that the learning achievement of learners is improved considerably compared to the previous one.

Learning communities in medical education have demonstrated favorable outcomes in terms of students' learning, professional development, and wellness. Despite these strengths and the widespread adoption of learning communities in US medical schools, there has been little interest in medical learning communities in Korea. In this context, the present study examined the development and implementation of the Yonsei Medical Learning Community (YMLC) and analyzed its outcomes and areas of improvement. The Yonsei University College of Medicine has operated a learning community as part of the undergraduate medical education curriculum since 2014. The YMLC is the first program of its type in Korea. The overall structure of the YMLC consists of four distinct communities (pillars), which are named after four distinguished alumni, and each pillar is organized into five learning community classes. Each class is vertically integrated across students in different medical school years, and one faculty advisor is matched to about 30 students. As the YMLC focuses on fostering reflective practice in students and providing them with opportunities to build teamwork and experience social relatedness, two educational approaches have been adopted: reflective writing and mentoring and community activities. In this study, we obtained and analyzed second-year students' feedback on the YMLC curriculum and identified its achievements, merits, and areas that need improvement. The results have shown that over 75% and 60% of respondents reported satisfaction with reflective writing and mentoring and community activities, respectively. The educational activities of the learning community helped students regularly reflect on their learning and progress and establish close relationships with faculty advisors. However, several areas of improvement regarding content, format, and logistical issues were also identified. The present findings may provide valuable information for other institutions to develop learning communities relevant to their own context.
