In this study, the instructional influences of the conceptual change model based on the cognitive conflict and the conceptual change model emphasizing the social consensus were investigated. The subjects were 109 7th-graders in a boys' middle school in Seoul, and were taught about the changes of states, density, and dissolution for 8 class periods. The hypotheses provided in the instructions were constructed from the results of a pilot test. Prior to the instructions, three tests regarding the perceptions of discussion, the attitudes toward science instructions, and the perceptions of participation were administered. Two types of the conceptual change instructions and the traditional instruction were used in the treatment groups and the control group, respectively. After the instructions, the students' achievement, the conceptions, the perceptions of discussion, the attitudes toward science instructions, and the perceptions of participation were investigated. ANCOVA results revealed that the scores of the treatment groups were significantly higher than those of the control group in the achievement test. Although the score of the treatment group using the conceptual change model emphasizing social consensus were higher than those of other groups in the conceptions test, the differences were not statistically significant. The perceptions of discussion were significantly more positive in the treatment group using the conceptual change model emphasizing social consensus than in the control group. However, there were no significant differences in the scores of the attitudes toward science class and the perceptions of participation among the three groups. Educational implications are discussed.

This study was to promote meaning ways of leaning and observe the influence of concept maps on middle school students' conceptual formation with regards to the topic of the 'sea water'. Concept map is one way to examine a leaner's conceptual formation process. The subjects of this study consisted of four classes within the first grade students of a Busan middle school, which were divided into two groups: the experimental group which applied concept map teaching and the ordinary teaching group. This study was carried out before and after class, examining the science leaning achievement, self-directed leaning characteristics, and awareness change on the concept maps. The result of this study was as follows: First, the leaning achievement of middle school students was positively affected by the use of concept maps. Second, the teaching method with concept map was more effective self-directed leaning characteristics compared to the ordinary one. Third, concept map teaching was a positive reaction to conceptual formation.

This study investigated the effects of cooperative learning environments in conceptual change instruction upon students' conception, achievement, learning motivation, attitude toward science instruction, and perception of involvement. Two classes of 8th graders at a co-ed middle school were assigned to the treatment and the comparison groups. They were taught about density, boiling point, freezing point, and solubility for 11 class hours. The treatment group's learning environment involved cooperative conceptual change instructions while the comparison group's environment incorporated individual conceptual change instructions. Mann-Whitney test results revealed that the scores of the conception and achievement test for the treatment group were significantly higher than those for the comparison group. The perceptions of involvement for the treatment group were more positive than those for the comparison group. The scores of the learning motivation test for the treatment group were found to be significantly higher than those for the comparison group based on a two-way ANCOVA analysis. However, attitudes toward science instruction were not found to be significantly different between the two groups.

The purpose of this study was to investigate the effect of concept sketches on the understanding and scientific attitude in high school student's learning of weather change. Among the various fields of meteorology, especially in weather change, we often deal with the change of the spatiotemporal change in an abstract way. So making use of 'Concept Sketches'- simplified sketches which represent the main features, principles, processes and interrelationships of the learning contents using some concise explanations, signs and terms - could help the students learn the phenomena of weather change efficiently. This study's aim was to check up the effect and analyze the results of the lesson including the concept sketches. As a result of this study, concept sketches group showed significant improvement compared to the other groups in understanding of weather change and in scientific attitude, too. In students' recognition research of concept sketches showed that students found the class more interesting with improved concentration and had a chance to review through concept sketching, which is helpful for their learning. Considering the above research results, the study which applies concept sketching required the students to actively process their knowledge, and had a positive effect on the understanding of weather changes. Most of all, drawing the pictures which is a familiar activity helped the students to take part in the class eagerly.

Concept mapping is a device for representing the conceptual structure of a subject discipline in a two dimensional form which is analogous to a road map. In the teaching and learning of earth science, each concept depends on its relationships to many others for meaning. Using concept mapping in teaching helps teachers and students to be more aware of the key concepts and relationships among them. The purpose of this study is to investigate the effect of the use of concept mapping on science achievement and the scientific attitude in ocean units of earth science. The results of this study are as follows; first, the science achievement of a group of concept mapping teaching is significantly higher than that of the group of traditional teaching. Also, when the achievement levels are compared among different cognitive ability groups, the effect is more significant in mid or lower level student groups than in high level groups. The use of concept mapping is more effective when the concepts have a distinct concept hierarchy. Second, the scores of the test of ‘attitude toward scientific inquiry’ and ‘application of scientific attitude’ of the group of concept mapping teaching are significantly higher than those of the group of traditional teaching, whereas the scores of the test of ‘interest in science learning’ of concept mapping teaching is not different from those of group of traditional teaching. Third, the survey on the use of concept mapping shows a positive response across the tested groups. The use of concept mapping is more beneficial in fostering the comprehension of the topic. A concept map of student's own construction facilitates the assessment of learning, thus promising the usefulness of concept mapping as a means of evaluation. In regard to retention aspect, concept mapping is considered to be more effective in confirming and remembering the topic, while less effective in the aspects of activity and interest. In conclusion, the use of concept maps makes learning an active meaningful process and improves student's academic achievement and scientific attitude. If the concept mapping is more effectively as an active teaching strategy, more meaningful learning will be attained.

In this modern society, the students should be able to recognize problems for themselves, and search the information which is valuable for them, and apply and utilize it. For these, we analyzed the effect of the discussion learning using the concept cartoons on the students' learning attitude and achievement. Even though there was no meaningful difference in the achievement between the experimental group and the control group, it was found that the discussion learning using the concept cartoons could be one of the ways that improve the students' problem solving ability. The fact that there was the significant affirmative effect on the students' positiveness when they were solving the problems was also found.

The development of Smart devices has become a key influence on the changes of the school system. As Smart education is integrated and institutionalized in school systems, how it is perceived and utilized by teachers should be investigated. This study is conducted to find out the perception of the teachers on characteristics of Smart education, using qualitative research method, and to analyze importance-performance, using additional quantitative analysis. To figure out the perceptions of the attributes of Smart education by teachers, related literatures were reviewed. The 8 teachers were selected and the data on their perceptions of Smart education were collected through direct observation of class and semi-structured in-depth interview. After researching, we finally drew out 16 final concepts, 6 sub-categories, and 3 categories in the open coding process. Based on the 16 concepts on teachers' perceptions on Smart education, importance-performance analysis (IPA) were conducted to identify areas that need focus and improvement. Based on the results of teachers' perceptions on importance of and the levels of use of Smart education, recommendations were provided for better practice of Smart education in school.

This study based on the 8-step strategy model for change management proposed by J. P. Kotter, tried to check the perception and experience about change management of the librarians at National Library of Korea. Also this study aimed to figure out the understanding of each 8-step strategy model. To this end, the concept and process of change management were presented through literature analysis, and survey was conducted targeting 58 librarians of the National Library of Korea. This study drews five results. First, the majority of librarians at National Library of Korea do not know about change management, and they do not have experience in using change management techniques. Second, the period required for the 8-step change management process is 5 years. Third, during the change management stage, librarians' awareness of the importance of stages 4 and 3 was high. Fourth, there is no difference in the librarians' perceptions of change management by gender, education, major, and tasks. Fifth, there is a significant difference in the age and service years of the librarian in the 3rd, 4th, and 7th stages of change management. Also there is a significant difference in the position of the librarian at the 1st and 3rd stage of change management, and between librarians' department and 1st stage of change management. The findings and results of this study can not only raise awareness of change management but also suggest organizational responses to change at individual or organizational level.
