Purpose: The purpose of this research was to develop and evaluate the effects of an empowerment program. Method: We developed an 8-week empowerment program to decrease cancer symptoms and increase self-efficacy, self-esteem, and empowerment. This program includes aspects concerning self-knowledge and management, self-help groups, self-advocacy, resource network, and laughter therapy. We evaluated the effects of this program on 32 home-based cancer patients (one group pretest-posttest design). The data collection was performed from August 22, 2011 to October 13, 2011. Data were analyzed using the SPSS/WIN 18.0 program. Result: There were significant differences in self-esteem derived from the empowerment program. However, there were no significant differences in cancer symptoms, self-efficacy, and empowerment after the program. Conclusion: More research, using a control group pretest-posttest design that considers an appropriate intervention duration, is needed to more accurately examine the effects of the program. We expect this intervention to improve the empowerment of home-based cancer patients.

The purpose of this study was to classify the types of scientific concepts by theoretical concepts and empirical concepts in physics, and to create cognitive conflict in students with logical statements and demonstrations, and to investigate conceptual changes. It seems that mechanics has much to do with the empirical concepts, and electromagnetics has much to do with the theoretical concepts. The condition of the instrument is intellegible, plausible, fruitful, and able to state and demonstrate. The instrument appropriate for these conditions was developed, which consisted of 6 items in mechanics and 6 items in electromagnetics, and conceptual changes were investigated. Structured interviews were conducted with 32 high school students to create cognitive conflict. We have elicited their ideas three times : pretest, posttest and delayed posttest. As the results of this study, demonstration method was more effective for conceptual change than logical argument method. In case of content areas, the misconceptions on mechanics concepts were changed more easily than those on electromagnetics concepts. In addition, the results of the study showed that the more cognitive conflict, the more the conceptual change was occurred.

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.
