This study was to inquire the effectiveness of concept mapping on the learning of biology concept. In this study the achivement acquired by the students in the classes of individual concept mapping and cooperative concept mapping were compared with those of traditional lecture on "photosynthesis and plant respiration". The concept mapping teaching methods, by individuals and groups. were more effective than traditional one. The results of analysis of covariance (ANCOVA) showed that these difference were statistically significant; individual concept mapping was more effective than traditional class result(p<.008). Also the cooperative concept mapping was effective than traditional class result(p<.0001). And the cooperative concept mapping was more effective than the individual one(p<.04). So that cooperative concept mapping is the most effective method in biology class.

This study explored a possibility of science concept learning in scientific practice-based science instruction through the review of literature about situated learning theories and practice-based science education. It was revealed that the situated learning theories were closely related to the recent trend in science education which emphasizes students' active engagement in scientific practices. From the perspective of situated learning, concept learning occurs in the process in which learners make use of concepts as resources and further develop the concepts through the emergence of conceptual agency during their participation in practices. The study also found that the situated learning perspectives could apply to science concept learning in scientific practice-based instruction: Science concepts are used as resources in practice-based science learning, students can better engage in scientific practices as they take advantage of science concepts as resources, and the emergence of conceptual agency can facilitate science concept learning during the participation in scientific practices. Implications for school science education were suggested.

Purpose: The purpose of this study was to identify and define the concept of cancer rehabilitation in the lives of cancer survivors. Methods: A hybrid model of concept development was used to interface theoretical analaysis and empirical observation with a focus on definition. A comprehensive literature review and semi-structured interviews with five cancer survivors were completed. Results: The concept of cancer rehabilitation was found to be a route toward a positive experience having meaning in two dimensions: recovery of the activities of daily living and intrapersonal growth. Four attributes and ten indicators were defined. Conclusion: Cancer rehabilitation was defined as a positive process of change through recovery of the activities of daily living and intrapersonal growth. Therefore, oncology nurses can be encouraged to design, implement, and evaluate cancer rehabilitation nursing interventions with the results of this study. Further research needs to develop cancer rehabilitation measurements.

The Five Laws of Library Science was introduced into Japan in 1935. After World War II, it was widely disseminated among young librarians by the education for librarianship developed in the 1950's. Its concept, "Books for All," met a serious opposition from local authorities based on their long continued concept of "preservation." After they realized that people eagerly use local libraries, they interpreted that the duty of public library was "lending books." They introduced "Privatization" of libraries into quite a few local libraries in order to save money. For overcoming problems, it is important to disseminate the library concept among the public, the assembly members and government officials planning to change their attitude of disregarding libraries. As the fundamental library philosophy, the Five Laws of Library Science is important. In the commentary of the Five Laws written by the present writer, he included an illustration of triangle pyramid showing the structure of the Five Laws. He included here the spiral of study on the library and the library science, based on the Section 814 of the Five Laws. He welcomes discussions on his Japanese angle from different viewpoints in order to develop further understanding of the Five Laws.

Infinity is one of the important concept in mathematics, science, philosophy etc. In history of mathematics, potential infinity concept conflicts with actual infinity concept. Reason that mathematicians refuse actual infinity concept during long period is because that actual infinity concept causes difficulty in our perceptions. This phenomenon is called epistemological obstacle by Brousseau. Potential infinity concept causes difficulty like history of development of infinity concept in mathematics learning. Even though students team about actual infinity concept, they use potential infinity concept in problem solving process. Therefore, we must make clear epistemological obstacles of infinity concept and must overcome them in learning of infinity concept. For this, it is useful to experience visualization about infinity concept. Also, it is to develop meta-cognition ability that students analyze and control their problem solving process. Conclusively, students must adjust potential infinity concept, and understand actual infinity concept that is defined in formal mathematics system.

The purpose of this study was to identify the influence of using the concept cartoons about middle school students' science attitude in the lessons on water cycle unit. For the purpose, they were developed to the learning program with concept cartoon and the instrument for the science attitude which has four categories; attitudes about science, attitudes about science subject, learning motives for science subject, and scientific attitudes. The research method was designed to quasi-experimental design. The concept cartoon was provided to the experimental group during nine lessons. Before and after the lessons in all two groups, the pre-post tests with the instrument were performed. The results from twice t-tests were shown that the domain of learning motives for science subject was only improved. From these, it were indicated that the concept cartoon was not effective all areas in science attitude, therefore the use in science lessons need to be restricted within narrow purpose.

The purpose of this study was to identify the effectiveness of science writing on organizing scientific knowledge and improving science process skills and science attitude, as science educators have indicated. For this study, two classes of $5^{th}$ grade students were chosen in the same elementary school. Subjects were divided into an experimental and a control group. The students in the experimental group took part in a science writing program for 14 lessons of science classes. The students in the control group were taught according to the traditional science program using standard science textbooks. To identify the effects of science writing, both groups' students were tested on science achievement, science process skills, and science attitude before the program implementation and were tested on science concept, science process skills, science attitude after the program implementation. The results of this study showed that the experimental group gains significantly higher scores than the control group in science concept and science attitude, but there was no significant difference on science process skills for either group. In conclusion, science writing had positive effects on science concept and science attitude of elementary school students, helping them to express their thinking logically and systematically, but science process skills were not affected.

Although many studies have investigated the effectiveness of concept mapping and the learning cycle, in Korea none have explored the effectiveness of concept mapping and the learning cycle combined. This study explored the effectiveness of concept mapping, the learning cycle, and a combination of concept mapping/learning cycle(CL) in high school biology class. Students' science achievement, the science related attitudes and scientific inquiry ability was measured. The results indicated that concept mapping, the learning cycle, and CL treatment were significantly different from the traditional one in science achievement(p< .05). However, the three treatments were not significantly different from each other. No significant difference exists among different learnings in high and average-ability students. But, concept mapping was the most effective in low-ability students. For the students' scientific inquiry ability, CL and learning cycle were more effective than concept mapping and traditional learning. No significant difference exists among different learnings in high-ability students. CL and learning cycle were more effective than concept mapping and traditional learning in average and low-ability students. For the students' science related attitudes, concept mapping, the learning cycle, and CL were more effective than the traditional learning. But, there was no significant difference among these three groups.

The purpose of this study is to investigate the effect of elementary pre-service teacher's science concept level on teaching difficulty, teaching satisfaction, and class evaluation. This study was conducted for 117 first grade students who are studying at P National University of Education. For this study, 117 students were divided into two groups according to the science concept level, and teaching difficulty, teaching satisfaction, and class evaluation score of the two groups were analyzed. The conclusion of this study is as follows. First, the elementary pre - service teacher group with a higher level of science concept showed significantly lower teaching difficulties than those with lower levels. This shows us that if primary pre-service teachers who have high science concept level, they can teach primary school science more effectively. Second, the elementary pre - service teacher group with high level of science concept got higher score on teaching satisfaction than the group with lower level of science concept, but it did not show statistically significant. Third, the elementary pre - service teachers with higher science concept level showed significantly higher scores on class evaluation than those with lower concept.

Purpose: Concept analysis is an essential part of theory development in nursing. Thus, many strategies or methods of concept analysis have been suggested in nursing literature. However, in Korea, only limited strategies were utilized, without much consideration on a wide range of strategies in choosing a method that coincides with the characteristics of each concept to analyze The purpose of this article was to propose various strategies for concept analysis. Method: A literature review method was used. Result: Ten methods of concept analysis were identified in the literature, and they were evaluated for advantages and limitations, In addition to the method by Walker and Avant and a hybrid model, more advanced strategies, such as triangulation method, critical analysis and the feminist approach were introduced and described in detail. The examples used in each concept analysis method were presented in table to provide the extent of utilization of each method. Conclusion: This article provides a wide range of strategies in identifying, clarifying, or elaborating a concept. It might help in choosing a method that best fits the concept to analyze, thus enhancing quality of concept analysis research.
