This study classified domestic and international systems by type, presenting their key features and examples, with the aim of outlining future directions for system development and research. AI-based learning assistance systems can be categorized into instructional-learning evaluation types and academic recommendation types, depending on their purpose. Instructional-learning evaluation types measure learners' levels through initial diagnostic assessments, provide customized learning, and offer adaptive feedback visualized based on learners' misconceptions identified through learning data. Academic recommendation types provide personalized academic pathways and a variety of information and functions to assist with overall school life, based on the big data held by schools. Based on these characteristics, future system development should clearly define the development purpose from the planning stage, considering data ethics and stability, and should not only approach from a technological perspective but also sufficiently reflect educational contexts.

As a measure of the center of data, arithmetical mean, median, mode, harmonic mean and geometric mean are generally used. Students must learn qualitative aspect of average values as well as its calculation for its adequate use. As the result of the learning, they should be able to select the appropriate average value according to the characteristic of data and problem context. For this object, the historical origin and visual interpretation of average values were introduced in this paper. And to help teaching several meanings of average values, several examples including context were suggested.

The concept of environmental education contains from teaching environmental pollutions and the importance of environment to the ecological relationship between human and the nature. The ultimate goal of environmental eduaction, however, is to build the environmental-friendly and responsible behavoir. One of the best way to achieve this goal is ecological learning centers, where students can observe and analyse threes, plants and animals, and they learn the principle of the environmental succession with feeling and understanding. Students internalize environmental awareness through experiencing the nature. In this paper, we would like to introduce the diverse types of ecological learning centers in germany and their programs focusing on the ecocenters in berlin, with an intention of adopting practical programs in korean school system.

Collaborative learning has been highlighted as an effective method of teachers' professional development in various studies. To disclose teachers' discourse threads in the process of collaborative learning for developing their knowledge, this paper adopted two methods including "content analysis" and "time-sequential analysis" of learning analytics. Such analyses were implemented for mining teachers' updated knowledge and the discourse threads in the discussion during collaborative learning. The materials for analysis involved two aspects: one was from the video-taped lesson observation reports written by teachers before and after discussing, and the other was from their discourses during the discussion process. The results proved that teachers' knowledge for teaching the centroid of a triangle was updated in the collaborative learning period, and also revealed the discourse threads of teachers' collaboration contained "requesting information or opinions", "building on ideas", and "providing evidence or reasoning", with the emphasis on "challenging ideas or re-focusing talk"

The purpose of this study is to explore improvable proposal of instruction through analyzing learners' needs and satisfaction for college of engineering. Based on the online survey date with undergraduate students in Seoul National University, recognition difference between students in college of engineering and all students in SNU was identified. Among several factors influenced on learners' satisfaction in class, it is shown that satisfaction to facilities is higher than any other factor related to instruction. Generally, satisfaction with teaching in class is lower while satisfaction to an extrinsic support to students is high. Therefore, instructors should be more concerned about teaching in class. Learners' satisfaction with instructors' feedback to assignments and tests is significantly higher in college of engineering. However, learners' satisfaction with the progress of classwork and assignment students should perform regularly is lower than one in other colleges.

Recently, the importance of creativity and problem-solving skills are being emphasized in engineering education. In particular, research is actively being conducted on learning models considering practicality or applicability in practice and education among many creative problem-solving methods. The objective of the present study is to develop a teaching and learning model and verify its effects in order to promote creative thinking and problem-solving skills using the TRIZ Contradiction Analysis. This study led the participants to obtain basic knowledge of creative engineering design through the creative engineering design course for freshmen at an engineering college, and come up with ideas and solutions using the TRIZ Contradiction Analysis. A survey was conducted and analyzed to verify the effectiveness of education using the proposed teaching and learning model, and as a result, the effectiveness of education has been proven by an average of 89 positive responses. Follow-up research is needed on improved application models so that the proposed learning model can be applied to various subjects.

The purpose of this study is to suggest implications for the development and revision of future teaching materials for mathematically gifted students by using network text analysis of secondary mathematics materials. Subjects of the analysis were learning goals of 110 teaching materials in a gifted education center in science attached to a university from 2002 to 2014. In analysing the frequency of the texts that appeared in the learning goals, key words were selected. A co-occurrence matrix of the key words was established, and a basic information of network, centrality, centralization, component, and k-core were deducted. For the analysis, KrKwic, KrTitle, and NetMiner4.0 programs were used, respectively. The results of this study were as follows. First, there was a pivot of the network formed with core hubs including 'diversity', 'understanding' 'concept' 'method', 'application', 'connection' 'problem solving', 'basic', 'real life', and 'thinking ability' in the whole network from 2002 to 2014. In addition, knowledge aspects were well reflected in teaching materials based on the centralization analysis. Second, network text analysis based on the three periods of the Mater Plan for the promotion of gifted education was conducted. As a result, a network was built up with 'understanding', and there were strong ties among 'question', 'answer', and 'problem solving' regardless of the periods. On the contrary, the centrality analysis showed that 'communication', 'discovery', and 'proof' only appeared in the first, second, and third period of Master Plan, respectively. Therefore, the results of this study suggest that affective aspects and activities with high cognitive process should be accompanied, and learning goals' mannerism and ahistoricism be prevented in developing and revising teaching materials.

The purpose of this study is to present a practical class design model that applies the problem-based learning (PBL) method to the subject of home economics. To begin with, a specific class model example was developed by conducting thorough document research and expert consulting. Two modules, named "Click! Global Leisure Environment" and "Happy Leisure Product Launching" were presented as the PBL questions. The case study focused upon in this research is an elective course called "Leisure Culture and Life Management". The 21 students enrolled in this course were considered in this study. Two teaching methods, namely a face-to-face teaching method and a web-based system "Snowboard" teaching method, were used to run the class. The research results are as follows: first, theoretical research and program development and demonstration were practiced with five different age groups: childhood, adolescence, university student, middle age, and senescence. Then, selfevaluation, peer evaluation, and group evaluation were conducted to motivate the students. Finally, a class evaluation was conducted by questioning the lecturer, who ranked well, scoring higher than or equal to 4.0 points out of 5.0 on all the questions. Through the PBL method, students showed an improved study attitude with more proactive participation in the class, they strengthened their communication skills and created a synergy with their team members. This study has significant meaning because it is the first research to apply the PBL method to home economics. Therefore, we expect other curricula to apply PBL and fully utilize this teaching method as well in the future.

The purpose of this study was to find a way to improve the basic learning ability of vocational college students and to develop the examination of learning attitude. This examination can be used at Center for Teaching and Learning as a previous step to find the strategy and effectiveness of learning. The examination of learning attitude which consisted of 33 questions was surveyed by 984 college freshmen. The survey revealed that five factors; effective content arrangement, priority and self-management, Check and improve of study habits, goal setting and implementation, learning plans have high interrelation(.53~.72). Especially, the more positive aptitude for their majors students had, the higher score they achieved in those five factors. According to general characteristics, there was significant difference among five factors. Therefore, if it is considered to run a differentiated Teaching and Learning method individually, it is expected to be more effective learning strategies.
