  • The purpose of this study was to analyze the understanding of the sighting and hearing elementary school students have through drawing. For this purpose, we conducted a questionnaire survey of 602 elementary school students. The questionnaire was composed with open-ended question developed by West et al.(2008). This questionnaire was presented only appearance of face. And let them express the sensory pathway by drawing and writing. The students' responses for questionnaire were classified by 5 levels. Inner-researcher consistency was 0.89, inter-researcher consistency was 0.83. The data analyzed were ${\chi}^2$ by using SPSS. The result of this study were as following: First, elementary school students have misconception of sighting and hearing. There were no difference among the grade. In spite of becoming upper grade, students have still misconception. Second, scientific concept that male students have were significantly more than female. Third, the concepts of the anatomically organs are more exposed in real-life situations, students known better. Within these results, it would be used for developing teaching-learning strategies which can use misconceptions students have.

  • The purposes of this study were grasping the degree of students' understanding for course contents through the concept mapping strategy as meaningful learning in science and measuring the effect for change of conception and changing the misconception. The results of the study were as follows: 1. Before the lesson, only 10.7% of students had scientific conception of molecular motion. Other students had various kinds of misconceptions. 2. The extent of concept formation after lesson through the using concept mapping strategy was tested. As a result, compared with the controlled group, the experimental group showed higher extent of sound concept formation (statistical significance level 0.05). 3. The differences between the experimental group and the control group were analyzed into quantitative and qualitative points of view. The results of the comparison showed that the maps of the students were well configured in the categories of the relationship, the hierarchy and the examples; while students showed lower abilities in the category of the cross-links. 4. The student's attitudes to ward concept mapping was positive. Most of the students answered that teaching strategy of concept mapping benefits them in meaningful learning outcomes.

  • This study researched the concepts that elementary school students have after having learned volcano and earthquake. The reacher collected and adjusted the journals related to this study, and sampled the concepts included in Chap. One "Moving Earth", the first term of the elementary school sixth year. The students' descriptive responses were analyzed after subjective questions on the basis of above were developed and put into. After the contents described in the answer sheets were categorized by key words and the types of concept were made out by qualitative analysis, it was showed what was differences between the sexual, regional and achievement levels. The results of this study were as follows; first, though the types of concept about volcano and earthquake were found variably, it was showed that wrong preconception was not corrected, especially the exact understanding about terms not attained to, which led to the trouble in conceptual readjustment of students. Second, though the response rate about the types of scientific concept was found high that volcano was made out of explosion and eruption of magma and lava, there were also children who described not the interior factor of globe but the surface factor. Third, according to the results divided into the interior factor of globe and the surface factor and analyzed about earthquake, there were a great number of children who responded as the surface factor though most of the students responded to the interior factor of globe. Fourth, through some types of concept, it was found that the formation of concept was much influenced by experience of children's life, curriculum, and the method of study. Fifth, In the most test question, the scientific concept was found that boys were higher than girls in the distinction of sex, the children of cities than those of town and island, and the upper group than the lower group in the achievement levels.

  • Some would argue that the search for the origin and treatment of this disease will continue over the next quarter century in much the same manner as it has in the recent past, by adding further layers of complexity to a scientific literature that is already complex almost beyond measure. But we anticipate otherwise: those researching the cancer problem will be practicing a dramatically different type of science than we have experienced over the past 25 years. Surely much of this change will be apparent at the technical level. But ultimately, the more fundamental change will be conceptual.

  • In this study, the influences of the context of discrepant events on the conceptual change process using cognitive conflict strategy were investigated in terms of students' cognitive and motivational variables such as cognitive conflict, situational interest, attention, effort, conceptual understanding. A preconception test was administered to 536 seventh graders. A test of response to a discrepant event and a situational interest questionnaire were then administered. The context of discrepant events, either scientific or everyday, was randomly presented to the subjects. After learning the concept of density, the tests of attention, effort, and conceptual understanding were administered. The reponses of 194 students who had been found to possess the target misconception were analyzed. The results revealed that the scientific-context discrepant event induced higher cognitive conflict than everyday-context one. The context of discrepant events, however, did not show significant correlations with situational interest, attention, effort, and/or conceptual understanding. The result of path analysis indicated that the context of discrepant events both directly influenced cognitive conflict and indirectly influenced conceptual understanding via cognitive conflict.

  • This paper proposes an approach in Southeast Asian studies using a post-colonial framework in the study of post-colonial Southeast Asia. This framework is based on the sociology of knowledge that analyzes the dialectical relationship between science, ideology, and discourse. Post-colonial studies is critical of the concept of universality in science and posits that a scientific statement of a society cannot stand alone, but is made by authors themselves who produce, use, and claim the so-called scientific statement. Several concepts in post-colonial theories can be used to develop area studies, i.e. colonial discourse, subaltern, mimicry, and hybridity. Therefore, this study also explores these concepts to develop a more comprehensive understanding of Southeast Asian culture. The development of post-colonial theories can be used to respond to the hegemony of social theories from Europe and the United States. The main contribution of area studies in the field of the social sciences and humanities is in revealing the hidden interests behind the universal social sciences.

  • The purpose of this study was to investigate the characteristics of high school students' conceptual understanding about minerals and rocks. A questionnaire was developed to examine students' conceptions of minerals and rocks. The data were collected from 93 students in 10th and 119 students in 11th grades in a high school. The result showed that students' understanding of minerals and rock was on the moderate level. The 10th grade students showed a relatively lower level of understanding about igneous rocks while the degree of the 11th graders' understanding about certain concepts related with melting point in the rock domain was a little bit lower than the average. Although the understanding levels between the two grade levels were similar, there were some items for which students understanding seemed to be more sophisticated with the grade. In the questions about the characteristic of basalt surface, however, the frequencies of non-scientific conceptions were not decreased, rather increased along with the grade. It was also found that the conceptions students acquired from other science lessons as well as earth science classrooms did rather interfere with students' construction of the scientific concepts of minerals and rocks even though sometimes they were helpful for learning. It was suggested that the teachers should understand that some specific terms in earth science have different meanings as they were used in other subjects.
