The purpose of this study was to development a model of problem solving instruction for improving practical skill-competence in technical high school. For the study, various literature researches were reviewed intensively about problem solving process, laboratory instruction's approaches and learning principals. The problem solving instruction process was composed with identifying problems, generating alternative solutions, investigation and research, choosing a solution, acting on a plan, modeling of problem solving, testing and evaluating, redesigning and improving. The skills schema combines a four domain of skilled activity, that is, cognitive skills, psychomotor skills, reactive skills and interactive skills. The problem solving instruction was composed with five major learning systems-emotional, social, cognitive, physical, and reflective-that can be used extensively as generic lesson plashing. The teacher serves as a coach or guide for student learning. As a facilitator, the teacher challenges, questions, and stimulates the students in their thinking, problem solving and self-directed study. In this process, students represent problem with think aloud, assume responsibility for their learning and move from teacher-centered to student-centered education.

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.

It is undeniably important to bring up a solution capability of arithmetic word problems in the elementary mathematical education. The goal of this study is to acquire the implication for remedial instruction on arithmetic word problems solving through surveying elementary school students' difficulties in the solving of arithmetic word problems. In order to do it, this study was intended to analyze the following two aspects. First, it was analyzed that they generally felt more difficulties in which field among addition, subtraction, multiplication and division word problems. Second, with the result of the first analysis, it was examined that they solved it by imagining as which sphere of the other word problems. Also, the cause of their error on the word problem solving was analyzed by the interview. From the foregoing analyses, the following implications for remedial instruction on arithmetic word problems solving are acquired. First, the accumulation of learning deficiency must be diminished through the remedial instruction. Second, it must help students to understand the given problem and to make of what the goal of problem is. Third, it must help students to form a good habit for reading the problem and to understand the context of problem. forth, the teacher must help students to review and reflect their problem-solving processes.

This study investigated the effectiveness of the Developmentally Appropriate Instruction Model for Science(DAIM-S) on increasing scientific curiosity and problem solving in young children. Subjects were 60 5-year-old middle class children, randomly assigned to one of two groups: either the DAIM-S group or the direct instruction group. For 2 months, the children in both groups took part in 21 science activity sessions. Both before and after treatment, subjects were tested on curiosity and scientific problem solving. The DAIM-S group showed higher achievement than the direct instruction group in the acquisition of curiosity and scientific problem solving. From these results, the researchers suggest application of the DIAM-S to the science teaching of young children.

실행연구는 연구자가 문제의식을 가지고 실제를 개선하고 자신의 전문적 지식을 향상시켜 나가는 연구이다. 본 연구는 학생들이 학교와 가정에서 수학을 많이 접함에도 불구하고 수학적 문제해결력이 낮고 실생활에 적용시키는 수학적 이해력이 부족하다는 문제점을 인식한 교사가 학생들의 수학적 이해력을 높이고 교사 자신의 수학 교수법을 계발하려 데서 출발하였다. 본 연구를 실행한 교사는 수학적 지식을 적용할 수 있는 문제 상황을 학생들 스스로가 잦아보게 하여 수학을 실생활에 적용할 줄 알고 수학과 친숙해지도록 하는 수학적 이해력을 신장시키기 위한 방안으로 상황중심의 문제해결 모형을 고안하였다. 본문에서는 교사가 연구자가 되어 학생들의 이해를 촉진시키기 위하여 개발한 상황중심의 수업 모형을 설명하고, 이를 적용하는 과정과 수업의 반성을 통해서 얻은 연구자의 성찰적 지식을 정리하였다.

The Environmental problem solving model is an instructional strategy to accomplish the aim of environmental education through investigation of environmental problems and issues of the community. This study is intended to compare the instructional effect of the structured model with the unstructured model of environmental problem solving. The experimental group received the structured instruction and the control group received the unstructured instruction. There did not appear to be any significant difference between the groups in regard to knowledge but in regard to knowledge of environmental issues, the experimental group was more effective than the control group. No significant differences existed between the groups in attitude. In regard to investigating skill and evaluation of environmental issues, the experimental group was significantly more effective than the control group. The experimental group was significantly more effective than the control group in regard to environmental action skills. To foster responsible environmental behavior, environmental education a number of methodologies must be considered and learners must be trained to become problem-solving citizens. It was noted that the structured instruction was more effective than the unstructured instruction in middle school where environmental issues were not taught as an independent subject. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its goals and the characteristics of the various learners. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its internal goals and the situations within which various types of learners explore environmental issues and solutions.
