In this study, we developed Internet Based Problem Solving Learning Model based on difficulty of internet based problem solving teaching and learning. For these, firstly we developed 7 Steps Problem Solving Model applying ICT-EUS into proper step. Next, we developed Internet Based Problem Solving Learning Model reflecting 7 Steps Problem Solving Model and searched an outline and characteristics of support system to apply the model into instruction. The teaching and learning model is composed of four steps of (1) design (2) preparation (3) teaching and learning execution (4) management, and 7 Steps Problem Solving Model is the core of teaching and learning execution step. The 7 Steps Problem Solving Model and Internet Based Problem Solving Learning Model are not for functional use but for general use. In other words they can be used commonly in all subjects.

There are several studies in order to learn about programming language. This paper develops a peer agent system based on teaching and learning strategies in order to improve problem-solving ability. Problem-solving ability involves three components - content understanding, domain-dependent problem-solving strategies, and self-regulation. This paper shows the teaching and learning strategies about components of problem-solving for learning to program and the peer agent system uses the teaching and learning strategies. This study intents to analyze the educational effects of the peer agent system. The results show that the system has superior effects on problem-solving ability compared to traditional programming courses or pair programming courses. It means that the peer agent system is the effective educational system in improving student's problem-solving ability.

This study was initiated to investigate sixth graders' gender characteristics in science problem solving process and thus find out the proper learning and teaching strategies for each gender. A total of 14 students, each of seven male and female students, were selected through three tests, including items of science knowledge, science inquiry, and creativity. Students were required to solve 26 items and to think aloud for researchers help understand how they thought in their problem solving process. Males and females showed some similarity and difference in four steps of problem solving process, understanding, planning, solving, and reviewing. We found gender differences in self-confidence of their answer. This study is expected to help develop teachers' differential teaching strategy for male and female students' science problem solving.

This paper investigates instructional strategies with potential for improving students' achievement in word problem solving. This review compares and analyzes the direct instruction (DI) and cognitively guided instruction (CGI) research on K-3 word problem solving mathematics students in a demonstration of my position that teachers need to understand student mathematical thinking to enhance students' achievement in word problem solving. CGI provides a more appropriate instructional model than DI for teaching word problem solving. For example, student-centered, conceptual understanding, and children's informal or invented problem solving strategies communicating with each other mathematically, etc. Korean teachers and teacher educators need to consider implementing CGI teaching strategies.

Creativity is a trait necessarily demanded in highly industrial and information oriented society. Accordingly, we should develop creativity through school education. The purpose of this study is to inquire a conceptual model and teaching method for developing creative problem solving skills in home economics education which can work at a platform for the curriculum developer. Although many definitions of creativity consider cognitive aspect more, personal or affective aspect is heavily involved with creativity. Therefore, creativity is a dynamic system which cooperates many contrasting and dialectic components in personal and cognitive aspects. The function of creativity is dependent on diverse environmental system. Environments influence on the extent of the development of creativity. Thus, the person-situation interaction model devised by Woodman and Schoenfeldt, integration of cognitive, affective, and situational aspects, is suggested as a conceptual model for teaching creativity in home economics education. The practical reasoning teaching model is suggested as a teaching method for developing creative problem solving skills in home economics education. The components of creative problem solving which involved with practical reasoning process are general knowledge and skills, specific knowledge and skills, divergent thinking skills, motivation and motives, and critical thinking skills.

In recent domestic and international curriculum it is emphasized that students should acquire 'problem solving' competence as a member of knowledge information society and various programming educational methods of improving problem solving competence have been studied. But there is no difference between programming problems in related research and traditional programming courses. Most methods of solving problems are focused on acquiring specific languages rather than enhancing problem solving ability. In this research, we developed a suitable programming problems and curriculum for fostering problem solving competence and designed and developed teaching and learning contents based on PSA(Problem Solving Activities). Furthermore, we obtained meaningful results of improving learners' problem solving ability and logical thinking ability by operating curriculum with developed contents as learning materials. The results of this research are expected to be used as a reference model or basic teaching materials for developing and operating the programming teaching and learning contents or curriculum to enhance problem solving competence.

With the recent revised curriculum, the importance of exploring children's play through new teaching media is increasing in kindergarten. In this study, it is to use the robot 'Bee-bot' for early children to uncover the changes that children have through free exploration and play. As a result of comparing the change of scientific problem-solving ability of 3, 4, and 5-year-olds, there were significant changes in all three sub-elements. We propose to us scientific problem-solving ability test tools, propose and apply ideas for problem-solving, conclusion on problem-solving Building. Through this, it was found that unplugged play using 'Bee-bot' is meaningful as a play environment and as a teaching medium for children aged 3, 4 and 5 years old.

The purpose of this study is to develop and apply the algorithm teaching materials centered on plays(ATMCP) to improve problem-solving abilities of elementary students. For this goal, the ATMCP were reviewed by the expert group and tested them out on 71 fifth-grade elementary students in Daegu, Korea during the 6 weeks. We divided students into two groups: one is the group of the ATMCP and the other is the group of conventional algorithm teaching materials(ATM). And we analyzed the change of the problem-solving ability of each group between before and after using two types of teaching materials with the Mixed ANOVA. The result showed that there was a significant difference in students' problem-solving abilities between before and after using them and the group of the ATMCP was greater improvement than the group of the conventional ATM in a problem-solving ability.

In this paper, we propose a new teaching-learning model with two-step feedback on programming language learning, which is a basic preliminary learning for programming. Programming learning is aimed at improving problem solving skills and thinking by experiencing problem solving through programming. For programming, the learner must know how to work with the computer and what to do with it. To do this, concrete thinking should be established and described in an accurate programming language. In recent, most studies have focused on the effects of programming learning and have not studied the effects of education on language itself. Therefore, in this study, the teaching-learning model for programming language education is presented and applied to the field, and the results are compared with the existing instructional-teaching model.

Children should have opportunities to experience problem solving individually with strategies for developing their problem solving abilities. To make an instructional design for individual teaming, problem solving activities were classified into categories like individual activities, individual activities within a group, and team teaching. A flow of teaching and teaming process was designed before, and concrete and semi-concrete materials were used in an experimental teaching, which was analysed in this research.
