교사들의 생각하는 과학학습의 목표는 학생들이 생각하는 과학학습의 목표와 다를 수 있다. 과학을 잘 하는 모습은 교사의 입장에서 볼 때 과학교수 목표를 의미한다. 그러한 의미에서 과학교사들은 학생들이 과학을 잘 하게 하기 위해 과학 수업을 하고 있다고 볼 수 있다. 그러나 과학을 잘하는 모습은 교사마다 다를 수 있기 때문에 교사마다 다른 지향점을 가지고 과학교수활동을 하게 된다. 본 연구의 목적은 예비 교사들의 과학을 잘하는 모습에 대한 인식을 탐색하는데 있다. 연구를 위해 과학을 전공하고 있는 1학년에서 4학년 사이의 예비교사 30명을 대상으로 개방형 질문으로 구성된 설문을 실시하였다. 연구결과 예비교사들이 지닌 과학을 잘 하는 모습에 대한 인식의 유형과 과학을 잘 하는 모습을 결정짓는 상황의 유형을 분류할 수 있었으며, 예비교사들의 과학을 잘하는 모습에 대한 인식과 과학교수목표의 차이를 확인할 수 있었다.

This study focused on characterizing various factors in order for learners to maintain their interests in learning and to maximize learning effects as the top priority purpose of university e-Learning, on the basis of results of conceptual studies on existing e-Learning and practical studies, and then on examining them practically. It also analyzed which factors would have greater influence on learning effects of e-Learning in general. Moreover, in comparison with existing numerous studies which examined only factor such as learning effects of e-Learning, it analyzed such things in detail according to division into three items such as learning satisfaction, learning transfer and learning recommendation. To achieve such purposes of the study, it characterized and set 3 factors such as learning contents, instructional design and user convenience on the assumption that such factors have a significant influence on learning effects of e-Learning. Moreover, the factor of learning contents includes 3 detailed elements, i.e., learning issue and objective, knowledge information, and consistency and propriety, and the factor of instructional design includes 4 detailed elements, i.e., interest and sympathy, interaction, contents presentation and explanatory strategy. Lastly, the factor of user convenience includes 2 detailed elements such as screen configuration, and check-up of contents and teaching schedule. According to analytical results, it showed all 3 factors such as learning contents, instructional design and user convenience have a significant influence on learning effects of e-Learning(i.e., learning satisfaction, learning transfer and learning recommendation). In more detail, it showed the learning issue and objective from the factor of learning contents have the greatest influence on learning satisfaction of e-Learning. Then, it is the most important to set the learning issue and objective with given priority to learners and set the learning objective estimable, in order to raise the learning satisfaction. It showed the contents presentation from the factor of instructional design on the learning transfer. Therefore, it is the most important to structuralize mutual relation and presentation orders to promote learning systematically and to let learners access to such things, for the purpose of raising the learning transfer. Moreover, it showed the interest and sympathy from the factor of instructional design has the greatest influence on the learning recommendation. Thus, it is the most important to promote learners' interests to the maximum using well-timed media, and to give a lecture enough to arouse learners' sympathy.

This study focuses on Social and Emotional Learning (SEL) as a theoretical perspective to provide education that enables adolescent students to understand themselves, establish healthy relationships with others, and form a healthy community. The meaning of learning and core competencies were analyzed. Results showed that the core competencies of SEL were all included in the nature, goals, subject competencies, core concepts, generalized knowledge, and achievement standards of the 2015 revised Home Economics Education (HEE) Curriculum. The implications for this are: First, the core competencies of SEL can be sufficiently cultivated through explicit education in HE classes without introducing a separate SEL program in the school field. Second, since HEE is a subject that emphasizes practice, the competencies of SEL can be applied in connection with actual life outside of school. Lastly, the effectiveness of SEL can be increased through HEE because the goals of SEL, which emphasize the connection between parents and the creation of healthy and safe community, are similar to the goals of HEE.

This paper is to examine new programme of study for geography by a revised geography(including historical, geographical and social understanding) National Curriculum in England. The new primary and secondary National Curriculum was respectively issued in 2007 for implementation from September 2008 and 2010 for implementation from September 2011. The revised National Curriculum was changed more than that of 1995 and 2000 in terms of its formation and content. Especially, Primary National Curriculum was rebuilded to the six areas of learning, in the end KS1-2 geography was integrated in 'historical, geographical and social understanding'. As a result of that, the subject named as geography only remains for KS3. Nevertheless, the new National Curriculum is consisted of programme of study(PoS) and attainment target(AT). But new programme of study was changed more than that of former curriculum in terms of its formation and content. Programme of study for primary school is organized with curriculum aims, the importance of areas of learning, essential knowledge, key skills, cross-curricular studies, breadth of learning and curriculum progression. On the other hand, that of geography for KS3 is organized with curriculum aims, the importance of geography, key concepts, key processes, range and content, curriculum opportunities. This paper examined on categorical features of new programme of study for KS3 geography and its implications for effective geography curriculum design and planning.

In this study, the effects of STAD cooperative learning strategy on students' achievement, learning motivation, perceptions of learning environment, and perceived classroom goal structure were investigated in terms of students' collectivism level. Two classes (64 students) from an elementary school were respectively assigned to a control group and a treatment group. A individualism-collectivism test, a learning motivation test, a perceptions of learning environment test, and a perceived classroom goal structure test were administered as pretests. The intervention of cooperative learning lasted for 24 class periods. After instruction, an achievement test, the learning motivation test, the perceptions of learning environment test, and the perceived classroom goal structure test were administered. The results indicated that the students of the treatment group significantly outperformed those of the control group in the achievement test. There was a significant treatment-aptitude interaction effect in the scores of the attention subcategory of the learning motivation. In the perceptions of learning environment, the score of the treatment group was significantly higher than the control group in the cohesiveness subcategory, whereas the score of the treatment group was significantly lower than their counterpart in the competitiveness subcategory. It was also found that the score of the treatment group was significantly higher than the control group in the performance subcategory of the perceived classroom goal structure.

This paper proposes a mobile AI (Artificial Intelligence) conducting decision-making in the game through education for intelligent character on the basis of Neural Network. Neural Network is learned through the input/output value of the algorithm which defines the game rule and the problem solving method. The learned character is able to perceive the circumstances and make proper action. In this paper, the mobile AI using Neural Network has been step-by-step designed, and a simple game has been materialized for its functional experiment. In this game, the goal, the character, and obstacles exist on regular 2D space, and the character, evading obstacles, has to move where the goal is. The mobile AI can achieve its goals in changing environment by learning the solution to several problems through the algorithm defined in each experiment. The defined algorithm and Neural Network are designed to make the input/output system the same. As the experimental results, the suggested mobile AI showed that it could perceive the circumstances to conduct action and to complete its mission. If mobile AI learns the defined algorithm even in the game of complex structure, its Neural Network will be able to show proper results even in the changing environment.
