This study presents how a professional development program (PD) of K-12 teachers affects participants' use of the earth system approach and their perceptions of using the urban environment for their science teaching and lesson unit development. This study utilized mixed methods to collect and analyze the data. Eleven urban teachers' pre-post lessons (45 lessons) were analyzed quantitatively using a lesson plan analysis tool, modified by the author, and their lesson reflections were analyzed qualitatively. The findings of this study show that the PD program influences the teachers to choose more topics and content knowledge based on the earth system approach and to assess the topics and content knowledge with more appropriate methods. Specifically, the teachers use more urban environmental factors/topics in their post lesson to teach the environmental topics of urban area. However, according to the statistical analysis of pre-and postlesson plan scores, the accuracy of the earth system knowledge that participants used in their lessons did not change significantly (p<0.05) (Table 4), which means that the PD program did not affect the improvement of the teacher's content knowledge in earth system science. Implications of this study are discussed.

Purpose: This study evaluated the effect of a teaching model to improve cultural competency (TMCC) for Korean undergraduate nursing students. Methods: A nonequivalent control group pretest/posttest quasi-experimental study was conducted with a convenience sample of 168 undergraduate nursing students in South Korea. The experimental group of 121 seniors was taught a 13-week teaching model in order to improve cultural competence. A control group with 47 junior students underwent nursing major courses, but did not take this teaching model. Before and after the program, students' level of cultural competency was measured using the Questionnaire for Cultural Competence (QCC) consisting of three sub-scales: "awareness and desire," "encounter," and "nursing skill and knowledge." Results: After the experiment, the experimental group showed significantly higher improvement in the Questionnaire for Cultural Competence in the three sub-scales of "awareness and desire," "encounter," and "nursing skill and knowledge" than the control group (p=<.050). Conclusion: A teaching model to improve cultural competence was effective in improving Korean undergraduate nursing students' cultural competency. Further studies need to be repeated in order to identify the effectiveness of the teaching model to improve cultural competency with graduate or clinical nurses.

We propose an efficient information science teaching-learning method to improve information-scientific creativity of mathematically and scientifically gifted students. The students are able to improve their creative problem solving and team-work abilities through team project work to resolve a variety of application problem in real world. In the pursuit of this purpose, we designed a new two-stage information science learning method consisted of the standard stage and the application stage, and a new systemic project process. Moreover, we applied small-scale cooperation learning strategies and a multi-dimensional assessment system. The analysis on our proposed model shows that there is a remarkable achievement of educational objectives on cognitive capability, social and affective ability of information science creativity.

This study investigated the effects and development of instruction module using ICT on earth field at elementary school science. The effects by 5th graders appeared as follows; First. ICT-applied teaching method proved to enhance the science teaming achievement regardless of their grades compared to the ordinary one. Second, Instruction module using ICT devoted to improve 'self-directed learning characteristics' at all grades by comparition of the ordinary teaching method. The 5th graders showed the improvements in the fields of' openness', 'self-conception', 'initiative', 'future inclination', 'creativity', 'self-assessment ability' all of which belong to self-directed teaming characteristics. They did not, however, show meaningful effect on improving 'learning eagerness' and 'responsibility' improvement. Thirdly, ICT-applied teaching method proved that it is more effective for developing 'creativity' than the ordinary one at all sample grades. The effectiveness was presented highly at 'fluency', 'originality' all of which belong to creativity. They did not, however, show meaningful effect on improving 'flexibility'.

The effects of three teaching models were compared in this research. One of those is concept change model, another is concept change model based on students learning motivations, the other is traditional teaching method based on science textbooks. The subjects of this research were the 8th grade students of Korean middle school. They were divided into three groups, and tested learning motivations. All of the three groups improved their learning motivations and concept understanding by the classes. Especially, the group of concept change model based on students learning motivations represented most effective improvement of learning motivations. The concept change teaching model and concept change teaching model based on students learning motivations are more effective in concept understanding than traditional teaching method based on textbooks. The students who have high learning motivations improved their concept understanding by the classes of concept change model based on students learning motivations. The students who have low learning motivations improved their learning motivations by the classes of concept change model based on students learning motivations also.

The purpose of the present study was to investigate an appropriate instructional model in order to remedy students' misconception. As hypotheses of this study, three instructional models, cognitive conflicting, hypothesis testing, and learning cycle models, on biological 'osmosis' concept were tested in 176 high school students. Results of the present study are as follows: 1. All groups used one of three instructional models showed a statistically significant improvement in conceptual change on the 'osmosis' concept between before and after the instruction. In addition, the three hypothesized instructional models were more effective in conceptual change than a traditional expository instruction. 2. There was a statistically significant difference among three experimental groups. Cognitive conflicting model and hypothesis testing model was more effective than learning cycle models. 3. An interviewing after instruction showed that students who had scientific concept on the 'osmosis' through the instruction could effectively apply the concept to other context more than students who had no scientific concept through instruction. The present study indicated that instructional model play an important role on students' conceptual change in science classroom. According to the result of this study, the instruction emphasizing students' active participation in class and scientific reasoning process is more appropriate to remedy misconception that the instruction using students' passive participation in class and expository teaching procedure. This study also indicated that students' concept acquired through instruction is one of important factors to apply it to other context.

One of the prerequisites for the improvement of the teaching of mathematics in our country is an improved curriculum-one which takes account of the increasing use of mathematics in science and technology and in other areas of knowledge and at the same time one which reflects recent advances in mathematics itself. In the new curriculum of mathematics, we have found the problems to teach the concept of sets at secondary level. The idea of a set is the most fundamental one in mathematics. So, this thesis contains the studies of the systematic analysis of sets in dealing with the traditional textbook. The scope of the work is limited to the fundamental ideas, and so it merely touches on the topics of the Concpets, Operations, Cardinal Numbers, Application of Logic, one-to-one Correspondence, Probability and so on. It provides only the essentials, definitions, proofs and some example which are already known and understood in their traditional context. It also presents at the appropriate stages the concepts required (illustrated by examples) in a much clearer fashion than classical teaching does. To compete a study of the sets covered in the textbook of each year, greater detail is needed at the appropriate level.
