There have been a number of lesson analysis studies, yet not many studies address the issue of the perspective of students who play a key role in the lesson along with the teacher. The purpose of this study is to investigate how the teacher and the students interpret the mathematics lesson they experienced, and to find out the potential discrepancy between the teacher and the students in their perceptions of mathematics lesson. To pursue this purpose, 10 consecutive lessons were videotaped in the 8th grade mathematics classroom, and the video-stimulated post-lesson interviews were also conducted with the teacher and the students. Based on the lesson videos and the interview data, six discrepancies between the teacher and the students in their perceptions of mathematics lesson were dentified: the discrepancy between the teacher's intention and students' interest in the lesson; different interpretation and response to the teacher's mistake; formal abidance; topaze effect; different recognition of the students' preference among the topics; teacher's insufficient response to students' needs. These six discrepancies were further categorized and some implications were drawn.

본연구는 자유낙하 운동에 대학 학생의 개념을 이 개념의 역사적 변천 과정과 비교하여 분석하였다. 네 연령층(ll세,13세, 15세, 17세)으로부터 총 737명이 설문조사에 참여하였으며,설문에서 주어전 문항들은 자유낙하 운동과 관련하여 과거의 과학자(예를 들어, 아리스토텔레스, 임페루스 이론가, 갈릴레오)들이 고민하였던 핵심 문제를 반영하는 것이었다. 설문에는 세 문항이 포함되었으며,각 문항은 자유낙하 운동에 관한 세 가지 측면(즉,운동의 원인,낙하높이와 낙하속력의 관계,낙하 체의 무게와 낙하속력의 관계)에 각각 관련된 것이었다. 낙하운동의 원인에 대혜서, 전체 학생의 4.3%, 25.5%. 62.7%가 아리스토텔레스,임페루스스,갈릴레오적 관점을 각각 지닌 것으로 나타났다. 낙하높이와 낙하속력의 관계에 대혜서는,20.0% 와 29.0%의 학생들이 각각 아리스토텔레스와 갈릴레오적 관점을 지닌 것으로 냐타났다. 그리고 낙하체와 무게와 낙하속력의 관계에 대혜서는,19.0%,34.8%,42.2%의 학생들이 아리스토텔레스,임페루스,갈리레오적 관점을 지닌 것으로 나타났다. 개별 문항에서 부분적으로 임페루스적 관점으로부터 갈릴레오적 관점으로의 변화가 나타났으나,전체적으로 연령이 증가함에 따라 학생의 개념이 현대적 관점으로 변화한다고 판단 하기는 어려웠다. 그리고 본 연구로부터 학생의 개념과 그 개념의 역사적 변천 과정에 사이에 상당한 유사성과 함께 차이점이 존제함을 알 수 있었다.

This study searched secondary school students' epistemological views and ontological views about nature and the root causes of such their views. The subjects were 156 secondary school students and data were gathered by the questionnaire developed based on preceding researches. As a result, many secondary school students had epistemological views of unknowable nature. There were various root causes of their epistemological views such as regularity and harmony of nature, predictable and circular natural phenomenon, causation, the relation between human and nature. On the other hand, a lot of secondary school students had ontological view of supernatural nature. Their religious beliefs were very powerful influence their supernatural ontological views. The nature is the object of science and the physical world. Because those views supply science educators basic backgrounds how leaners understand science class, secondary school students' epistemological views and ontological views are precious information. From now on, it is necessary to study relations between students' epistemological views and ontological views and their science class processes.

This study aims to examine two hypothetical models for the variables of students' environmental perspective. First hypothetical model is the mediating role of recognition and familiarity between aesthetic and negativistic perspectives. Second hypothetical model is the separate path from humanistic to dominionistic perspectives. One hundred four tenth grade students participated in this study. We used Pearson correlation, partial correlation, and path analysis to examine the fitness of hypothetical models. The findings showed that the mediating role of recognition and familiarity between aesthetic and negativistic perspectives were statistically accepted. To prevent students' bias for fancy or gross animals, the learning (for instance, recognition and familiarity) may play role in reducing the bias. Second, there were two differential paths from humanistic to dominionistic perspectives (ecologistic-naturalistic path and scientistic-utilitarian path). While ecologistic-naturalistic path does not reach dominionistic perspective, scientistic-utilitarian path does reach dominionistic perspective. To prevent students' dominionistic perspective for nature, they need to understand ecologistic-naturalistic minds for the nature.

In this study, elementary school students' views about nature were searched. The participants were 18 students of fifth grade and sixth grade. Data were collected via semi-structured interviews involving a set of elicitation devices used to encourage students to talk about their views about nature, The results showed as follows; (1) Elementary school students had diverse views and common views about nature, (2) Their views about nature were affected by various factors, such as religion, aesthetical aspect, science, society, and so on. So when science educators construct science curriculum, they must consider these factors. (3) It is necessary to be concerned about the relations between science curriculum and others.

The purpose of this research was to investigate the nature of the science views of science teachers and high school students as well as the views expressed in 10th grade science textbooks. The subjects were a high school science teacher, 18 male students and 11 female students in a 10th grade class located in Gyeongbuk Province, Korea. The data were analyzed in terms of three main categories of the nature of the science: the definition of science, the development of science, and the method of science. In the results, it was found that the textbook had an inductivism point of view, and that the teacher had a falsificationism point of view in terms of the definition of science. However, the teacher presented the inductive point of view of the textbook in the class. After the class, the students showed an inductive point of view. In terms of scientific development, the textbook represented a relativism point of view briefly, and the viewpoint of the teacher also expressed relativism. The teacher taught briefly from the relativism point of view, as in the textbook. The viewpoints of the students were inductivism and were not affected by the textbook or the explanations of the teacher. In terms of scientific methods, the viewpoints of the textbook and the teacher were falsificationism, and the teacher represented falsificationism views in her classes. The views of the students also showed falsificationism after their classes. However, before conclusions can be made, it is necessary to find concrete proof of the teaching effect on the viewpoints of the students in continuing research.

The purpose of this study was to investigate students' and teachers' views on the necessity of learning science in Korea. To grade sixth students(n=565) and teachers(n=57) of elementary schools in Seoul, Korea, a question, "Why do we have to learn science?", requiring a short essay of more than 7 lines including the reason and examples was given. From the analysis of short essays with the network analysis, it was found that most students and teachers had views of "we have to learn science to make personal everyday-life easy in aspect of personal usefulness and human everyday-life easy in aspect of social usefulness" with focusing on external value of science and taking examples of everyday-life related. And it was found that students' and teachers' views were somewhat biased toward focusing on external values of science.

This study was to investigate high school students' philosophical views on science and positions of constructivists; Popper, Lakatos, Toulmin, and Kuhn. The results of this study were as follows: First, most students had the eclectic position(69%): similar percentages in sex(male 67%, female 75%), stream(liberal art 72%, science 74%), and of having experience on reading books or magazines related to the philosophy of science(ever 78%, never 64%). Second, in analysis of ANDVA of science philosphical perspectives by experience of reading books, magazines, and matters related to the philosophy of science, significant difference was revealed(p<.01). Students who had ever heard of or read about the philosophy of science were tend to have Empiricism. Third, ANDVA analysis of constructivist philosphical perspectives showed that male students were nearer to Kuhn's position than female(p<.05) and students in science stream were closer to Popper than in liberal art(p<.05). And male students in science party showed a great tendency to consent Popper's perspective(p<.01). This result seems to suggest that male students tended to think social aspects more deeply than female and held Kuhn's position.

Student understanding of the nature of science is necessary not only because it is helpful for solving everyday problems with growing science literacy, but also because it influences students' science learning. Therefore, it was necessary to investigate student views on the nature of science under the 7th national curriculum and compare with those before the 7th national curriculum in order to probe the elements which contribute to changes in student views on the nature of science. A significant number of differences were found between subdimensions of views on the nature of science through the comparison. High school students under the 7th national curriculum had more relativistic, instrumental, and deductive but less process-oriented views than high school students before the 7th national curriculum. The differences between mean values which showed high school student views on the nature of science under and before the 7th national curriculum were significant, except for the subdimension of instrumentanlism/realism. In particular, high school students under the 7th national curriculum possessed a contextual view, whereas those before the 7th national curriculum possessed a decontextual view. Although other factors might be the cause for differences found in this study, we argued by discussion that differences among textbook contents seemed to be the major factor.
