  • Reasonable and reliable assessment method is one of the most important issues in science education, Partial credits method is an effective tool for assessing students' science inquiry problem solving. The purposes of this study were to classify the Problem solving types based on the analysis of the thinking Process, and how much the related science concept and the science process skills were used in solving science inquiry problems, and to describe the possibility and rationality of the assessment method that gives partial credit 128 high school seniors were selected and their answers were analyzed to identify science concepts they used to solve each problem, and the result was used as the criterion in the scientific concept test development. Also, to study the science inquiry problem solving type, 152 high school seniors were selected, and protocols were made from audio-taped data of their problem solving process through a think-aloud method and retrospective interviews. In order to get a raw data needed in statistical comparison of reliability, discrimination and the difficulty of the test and the production of the regression equation that determines the ratio of partial credit, 640 students were selected and they were given a science inquiry problem test, a science process skills test, and a scientific concept test. Research result suggested it is more reasonable and reliable to switch to the assessment method that applies partial credit to different problem solving types based on the analysis of the thinking process in problem solving process, instead of the dichotomous credit method.

  • Purpose: This investigation examined the effect of PBL on the meta-cognition, critical thinking, and problem solving process. Method: The research design was pre-posttest with a none qui valent control group design. Scenarios for PBL sessions were developed on the basis of textbooks and patients' charts and tested for content validity. Seventy six nursing students who took a 'Nursing Process' course from two nursing schools participated in the experimental group and control group. The experimental group performed PBL during the semester. Meta-cognition and problem solving processes were assessed by questionnaires which were developed using pedagogics. Critical thinking was measured by the CCTST(California Critical Thinking Skill Test) Form 2000. The data was analyzed by repeated measure (pretest-posttest) MANOVA, and correlation analysis. Result: PBL improved the participants' meta-cognition and problem solving process but not critical thinking. The relationship between meta-cognition and the problem solving process was supported but the relationship between critical thinking and problem solving was not supported. Conclusion: These results suggest that PBL has a positive effect on nursing students' educational outcomes. To improve the problem solving ability of nursing students, PBL should be applied to more subjects in the nursing curriculum.

  • Purpose: The purpose of this study was to identify the change of critical thinking disposition and problem solving process in students who experienced problem-based learning. Method: This research design was one group pre-post test design. Twenty-five nursing students who participated in ‘'Nursing Process' course with two PBL packages for a semester in 2004 were the subjects of this study. The data were analyzed by repeated measures of ANOVA, and content analysis. Result: The problem defining in problem solving process was improved significantly, but there was no significant difference in the critical thinking disposition. Conclusion: The results of this study suggest that PBL has a positive effect on nursing students' problem solving process, But for a more significant effect on a continuous base for critical thinking of nursing students, faculties should use web based and simulation-based education for self directed learning along with clinical situation-based scenarios.

  • Purpose: The purpose of this study was to investigate factors which influence the process of problem solving in nursing students during clinical practice. Method: Data were collected by questionnaires from 511 nursing students in from April 10 to June 10, 2011. Data were analyzed by Pearson's correlation coefficients and multiple regression procedures. Result: The values regarding self-leadership (mean 3.62), self-directed learning readiness (mean 3.53) and problem solving process (mean 3.37) were higher than the median. There were significant correlations between all the predictive variables and the process of problem solving. The greatest factors influencing the process of problem solving in nursing students were self-leadership and self-directed learning readiness (54.3%). Conclusion: By using the results of this study as a foundation, nursing education curriculum should be comprised of self-leadership and self-directed learning readiness for improvement of nursing students' problem solving process.

  • The purpose of this study is to analyze thinking process in problem solving and to get some teaching materials to improve students' problem solving abilities. For this study, 14 girl and boy students in highschool were tested with 7 testing questions. The whole process of students' problem solving was observed by using 'Thinking aloud', recorded by Audio Tape and finally drawn up to Protocol. On the basis of that Protocol, coding system was set up and characteristics of thinking process in each stage were analyzed. -In the stage of planning, successful problem solvers tried to check the properties of words included in problems(Pr) and made it clear that they were seeking(O) -In the stage of planning, students used abstraction strategy(Ab, making equation(E) or using variable(V)) appropriately could solve more difficult problems. Successful problem solvers turned used unsystematical trial into systematical method and were good at using partial objects, assistant factors. - In the stage of carring out the plan, successful problem solvers to reduce the error, check the purpose, used formula, knowledge and calculation. -In the looking back stage, successful problem solvers generalized the answer and checked the total process.

  • 수학과 교육과정에서 수학 문제해결력 신장, 수학 문제만들기 등이 꾸준히 강조되고 있다. 본 연구에서는 Brown & Walter가 제안한 what-if-not 방법과는 다른 방향의 문제만들기 방법을 연구하였다. 여기서 다루는 문제만들기 방법에서는 출발점 문제의 문제해결 과정을 분석하여 그 구성 요소들을 변화시키며, 얻어진 변화를 바탕으로 문제해결 과정을 역으로 거슬러 올라가면서 새로운 문제, 즉 출발점 문제를 변형시킨 문제를 만들었다. 이러한 순서로 문제를 만들면, 문제해결 과정으로부터 새로운 변형된 문제가 유도될 수 있다. 즉, 문제해결 과정이 문제에 선행하게 되며, 본 연구에서는 이러한 문제만들기 방법을 연역적 문제만들기라고 명명하였다. 특히, 연역적 문제만들기의 다양한 사례들, 특징들을 구체적으로 제시하였으며, 치환을 이용하여 로그가 포함된 방정식으로부터 지수, 무리식, 삼각함수가 포함된 방정식 등을 만드는 과정을 소개하였다. 연역적 문제만들기는 문제해결의 반성 단계에서 문제해결 결과를 검증하고 확장하는 활동과 관련될 수 있으며, 수학 교사가 개념 정착, 복습 등과 같은 교수학적 목적에 따라 기존 문제를 변형시킬 때도 활용할 수 있을 것으로 기대된다.

  • The purpose of the article is to address a new instructional approach to a complex engineering course. We design a novel instructional method that combines mobile technology, simulation program, collaborative teamwork, problem-solving process, and a variety of evaluation techniques. We suggested five instructional principles that might be required to change the fundamental educational process by which learning is done. The proposed instructional method is expected to aspire for new perspectives on complex learning environment. Nevertheless we solely began by the research on the development of students' complex problem-solving performance in a complex engineering course, the new instructional method in the article can promote the adoption of new instructional methods and strategies across different knowledge domains. In addition, the instructional method can provide a valuable bridge to acquisition and transfer of problem solving, motivation, and meaning learning.
