This study was conducted to examine mediative effects of two factors, emotion control and thinking control, in the relationship between avoid fusion and attention. Participants (308 high school students) were asked to complete a questionnaire which contains items to measure some psychological properties such as emotion control (EC), thinking control (TC), avoidance avoid fusion (CF), conceration(Co) and learning attitude(LA). Structural equation model analysis showed that 8 of modified 9 paths were statistically significant; CF to Co and TC, TC to EC, Co, and LA, EC to Co and LA, and Co to LA. Limitations and suggestions were mentioned in the discussion.

미래의 지식기반사회를 준비하기 위한 컴퓨터 교육이 나아가야할 방향은 컴퓨터 과학교육의 강조이며 또한 컴퓨터 과학교육은 프로그래밍과 알고리즘 등의 내용을 학습하고 이를 통해 컴퓨터의 기본 원리와 논리적인 사고력을 배양해야 한다는 많은 연구가 있었다. 이에 본 논문에서는 컴퓨터 과학교육의 중요한 한 부분인 알고리즘을 초등 컴퓨터 교육에 적용하여 학습자가 컴퓨터 알고리즘과 알고리즘의 과정을 이해하고 더 나아가 자신만의 알고리즘을 개발하는 과정을 통해 알고리즘적 사고능력을 기를 수 있도록 학습내용을 선정, 조직하여 적용하였다. 인지발달이 구체적 조작기에 머물고 있는 학습자들의 인지수준을 고려하여 문제해결학습모형을 기반으로 하여 구체적 조작활동이 포함된 교수-학습 모형을 구안해 적용해보았다.

"Ito2", an early childhood educational coding game that allows students to learn sequential, loop, and conditional statement concepts through games is introduced. The developed game is a two-stage process of mock and practical classes for children in actual nursing cares, and coding education is conducted for actual children to determine its effectiveness. The degree of change is observed by observing trends in childhood cognitive development performance in all six areas, including parts and the overall, space, observation, shape and measurement, classification, comparison, and listing, as the coding training is conducted. In this paper, the improvement of cognitive development and spatial perceptual abilities were achieved by children playing games with infant functional coding with fun elements plus learning factors.

The study to improve engineering students' performance in studying physics lacked despite of the importance of studying physics in engineering education. The cognitive belief and the motivational belief in studying physics had a strong effect on studying physics. The purpose of this study was to seek the educational way through comparing professors' expectations with students' beliefs about the cognitive belief and the motivational belief in studying physics. The cognitive belief in studying physics was considered as variables like 'knowledge', 'learning' and 'relation'. The motivational belief in studying physics was considered as variables like 'expectancy' and 'value'. It was the 'expectancy' that was the most different dimension between professors' expectations and students' beliefs. It means that students have little confidence in their abilities to study physics, though professors expect their students to be confident. Professor who teaches physics to engineering students recognize these differences, need to have interest in affective domains of beliefs to teach. In addition, there is need to teaching and learning strategies that can lead engineering students' beliefs about ability to perform the task, the purpose, importance, interesting for physics.

Various forms of visual representations enable scientific discovery and scientific reasoning when scientists conduct research. Similarly, in science education, visual representations are important as a means to promote students' understanding of science concepts and scientific thinking skills. To provide a framework that could facilitate the effective use of visual representations in science classroom and systemic science education research, a visual representation competence taxonomy (VRC-T) was developed in this study. VRC-T includes two dimensions: the type of visual representation, and the cognitive process of visual representation. The initial categories for each dimension were developed based on literature review. Then validation and revision was made by conducting teachers' workshop and survey to experts. The types of visual representations were grouped into 3 categories (descriptive, procedural, and explanative representations) and the cognitive processes were grouped into 3 categories (interpretation, integration, and construction). The sub categories of each dimension and the validation process would be explained in detail.

In this study, the relationships among students' cognitive/affective variables, cognitive conflict induced by anomalous data, and conceptual change were investigated. Tests regarding background knowledge, field dependence-independence, learning strategy, logical thinking ability, goal orientation, self-efficacy on prior concept and ability, and control belief were administered. Tests of prior conceptions, responses to anomalous data, conception, and retention of conception were also administered. There were no significant correlations of cognitive conflict induced by anomalous data with students' cognitive and affective variables. However, prior knowledge on molecular motion, field dependence-independence, and learning strategy were significantly correlated with students' conception and retention of conception. Logical thinking ability was also correlated with their conception. Multiple regression analysis indicated that learning strategy significantly predicted students' conception and retention of conception. For the affective variables, self-efficacy on ability was significantly correlated with students' conception and retention of conception, and goal orientation was correlated with their conception. Self-efficacy on ability was a significant predictor on students' conception and retention of conception, and goal orientation on their conception.

The purpose of this study was to investigate the level of self-regulated learning ability for engineering students. Self-regulated learning theory has been studied as the theoretical background and assessment framework explaining life-long ability. A survey was conducted to engineering students from an engineering-centered university, located in Seoul. The research findings were as follows. First, each mean of cognitive regulation, motivation regulation, and behavior regulation was 3.041, 3.051, and 2.996 respectively, indicating that the scores were not high. Second, there was no significant difference in the mean score of self-regulated learning ability between female and male students. Third, students in ABEEK accredited program scored meaningfully higher than students in non-accredited program on only 3 sub-components of organization strategy, metacognition, and task value. Fourth, senior students scored meaningfully higher than 1st year students on only 3 sub-components of metacognition, intrinsic motivation, learning environment management. The results revealed that instructional interventions should be provided for engineering students to develop self-regulated learning ability.

알츠하이머성 치매는 현존하는 치료법이 없어 경도인지장애 단계에서의 예방이 중요하다. 지금까지의 알츠하이머 연구는 대부분이 뇌영상 마커와 뇌척수액 마커에 집중되어 있었으며, 경도 인지 장애 단계에서의 탐색은 더욱 적었다. 이러한 점에서 혈액 유전자 발현을 이용한 경도 인지장애 단계 예측은 인지 능력에 따른 관련 유전자 식별과 접근 가능한 진단 및 치료 바이오 마커 탐색에 기여할 수 있다. 그러나 유전자 발현 데이터의 경우 환자 수에 비해 높은 차원을 가지기 때문에 과적합을 막고 질병 관련 유전자를 식별하기 위해서는 데이터에서의 의미 있는 차원만을 뽑아내는 차원 축소가 선행되야 한다. 본 연구는 유전자 발현데이터에서의 인지장애 분류를 위해 차원 축소기법과 신경망을 적용하여 인지 장애 정도를 예측하였다. 그 결과, Lasso 이용 차원축소와 신경망을 이용하여 97%의 정확도로 정상과 조기 경도 인지장애, 후기 경도 인지장애 환자를 분류 할 수 있었으며, 더 적은 차원에서도 분류가 가능했다. 이는 혈액 유전자 발현을 이용해 경도 인지장애 단계를 예측한 첫 번째 연구이며, 인지능력 저하에 따른 혈액 유전자 발현의 연관성을 확인하고 향후 조기 진단, 치료 표적 탐색에 기여한다.

In this work, we developed educational contents for ASP programming efficiency. These contents are applied to the cognitive apprentice model, one of the teaching-learning models based in constructivism. Specifically the functions of these contents are as follows: Learners can learn from the lecturing video made of multimedia, they have practical programming training according to the lecturing video showing illustration executed similar to a practical environment, and they grasp level of their understanding by themselves as doing the assigned tasks. Therefore we can anticipate for learning effects, because the contents that we developed can induce learners to learn by themselves and interest them in programming practice.
