The purpose of this study is to investigate middle school students' perceptions of private academy science education and of school science education in order to promote school science education. 180 middle school students who were taking a science class at a private academy were participated, and the short form of Classroom Environment Scale was implemented for the study. The results showed that the students went to an academy for supplementing school science or for getting a better grade in school. Some students, however, have different reason to go to an academy; they were kinds of silence-learners or received-learners rather than constructed-learners. That is, they didn't know how to and what to study. Students didn't have an opportunity to think scientifically and creatively from both academy and school science classes. They studied harder in science class at private academy than at school. Some students felt more favorable to and comfortable with academy teachers compare to school science teachers.

The purpose of this study was to investigate the perception of school teachers in science research ethics and perception of science research ethics education. A survey was administered for this study and a total 167 elementary and secondary teachers studying in K University graduate school participated. The survey was organized to examine participants' 1) science research ethics awareness, 2) status of science research ethics education, and 3) needs for science research ethics education, and 4) the perception of the direction of the science research ethics education in school. Each item was responded using either 1 to 5 Likert type scale, multiple choices questionnaires. The results were as follows: both of elementary and secondary school teachers showed above average interest in science research ethics and secondary school teachers showed significantly higher interest than elementary school teachers(p<0.05). In degree of awareness of science research ethics, plagiarism (M=3.98) was the highest, followed by free-riding(M=3.78), the scientist's social responsibility(M=3.71), and forge(M=3.61). In response science research ethics problem occurs in science education activities more than the average(M=3.39). Teacher's response on the teaching of science research ethics ranges from 3.02 to 4.47, but each science research ethics elements was showed a large deviation. Elementary and secondary school teachers responded that science research ethics education needed(M=4.34). Science research ethics education should be included in the school curriculum. Eighty-five percent of the teachers responded that the science research ethics education should be started from elementary school. 'Discussion-type classes with examples' was preferred as an effective teaching. And teachers needed 'instructional materials' and 'teachers training' for science research ethics education.

The purpose of this study is to discover and develop any implications which may arise in relation to science teachers' professional growth and development by investigating the difficulties experienced by elementary school teachers in science classes. 196 elementary school teachers were requested to write an anecdotal report regarding their science lessons. 30 science teachers in middle school also answered the same questionnaire. By means of inductive categorical analyzing, the difficulties were grouped into several categories. The results were as follows: (1) The difficulties elementary teachers experience in their science lessons fall into three categories; 'professional science knowledge(9.8%)', 'science laboratory activities(78.3%)', 'teaching methodology(11.2%)'. (2) Science teachers in middle school experienced similar difficulties. However, distribution differed from that of elementary school teachers; 'professional science knowledge(39.0%)', 'science laboratory activities(35.6%)', 'teaching methodology(27.1%)'. (3) The causes of these difficulties were identified as follows; a lack of time to prepare for science classes, insufficient substantial pre-service teacher education, and a lack of adaptive support to elementary school teachers.

This study sets out to assess the scientific literacy of secondary school students and to describe their differences according to gender, grade, course. This study involved 112 middle school students and 213 high school students. Their scientific literacy was measured by the Scientific Literacy Test designed by Manhart (1997). A 70-item multiple-choice test was used to assess their scientific literacy. The constructs of science factor included 36 items making up physical science, life science, and earth science subtests. The social aspects of science factor consisted of 34 items in nature of scientific inquiry/knowledge, science as a human endeavor, science and technology, and societal perspectives. A two-way analysis of variance (ANOVA) and t-test were conducted using the SPSS program. The scientific literacy score of the middle school students was 45.17. There was no significant difference according to gender but boys tended to perform better than girls on both the constructs of science factor and the social aspects of science factor. The scientific literacy score of the high school students was 51.79. There was no significant difference according to gender. But, boys tended to perform better than girls on the constructs of science factor. Girls tended to perform better than boys on the social aspects of science factor. The students taking a course on natural science got statistically higher scores than the students taking a course on humanities. The high school students got statistically higher scores than the middle school students.

The Natural Science High School is specialized in vocational education or training related to natural sciences such as biology or chemistry. Therefore, natural science high school students are expected to possess a high level of science learning motivation. This study aims to explore natural science high school students' level and structure of science learning motivation by comparing students in general high school. One hundred ninety three students from a natural science high school and 208 from a general high school participated in this study. We administered a questionnaire that consisted of seven science motivation components: 1) career motivation; 2) science grade motivation; 3) understanding the relevance of scientific knowledge; 4) need for learning science; 5) self-determination; 6) self-efficacy; and 7) attitudes toward science class. We employed independent t-test, path analysis, bivariate correlation, and stepwise multiple-regression for the statistical analyses. Our findings illustrated that the natural science high school students' levels on all seven variables were significantly lower than the general high school students.' The path analysis illustrated that career motivation and science grade motivation had relatively stronger influence on self-determination and self-efficacy in the natural science high school student sample than in the general high student sample. The explanatory powers of four independent variables (career motivation, science grade motivation, understanding the relevance of scientific knowledge, and need for learning science) predicting self-determination and self-efficacy were 30% higher in the natural science high school student sample than in the general science high student sample. These results suggested that natural science high school students' science learning motivation may be easier to change by extrinsic motivations such as career and science grade motivation.

Science textbooks which were compiled by CHOSUN Government General are known as books which appeared after 'Science Textbook for Common School' (1923-) compiled by CHOSUN Government General which are almost similar to state authorized textbooks and are also known as leaving the effect on 'Science Textbook for Elementary School' (1931-) which were focused on the subjects being issued since then and 'Science Text for Elementary Course' (1942-) being compiled by the Education Ministry, However in this research it was found out that there were publications in 1911, 1913 and 1921 and they were harbingers for 'Science Textbook for Elementary School' 0931-). For this reason it was decided to report overall picture on the science textbooks being compiled by CHOSUN Government General. And it was possible to illustrate that such textbooks can be classified into following 5 periods ; The 1st period:The time for search--'Science Textbook for Students of Common school' 1911 compiled by CHOSUN Government General. The 2nd period:Commencing separate compilation--'Science Textbook for Common School' 1913 compiled by CHOSUN Government General. (The 2'nd period:Final Separate Compilation-- Reissue after corrections of 'Science Textbook for Common School' compiled by CHOSUN Government General, 1921.) The 3rd period:Same as the state authorized science textbook of Japan--' Science Textbook for Common School' compiled by CHOSUN Government General, totally 3 books 1923-. The 4th period:Separate compilation, centered on subjects--'Science Textbook for Elementary School' compiled by CHOSUN Government General, 1931-. (The 4'th period:Changers of subjects--'Science Text for Elementary School' compiled by CHOSUN Government General, 1937-. The 5th period:Matched to compiled by the Education Ministry--'Observation of Nature' compiled by CHOSUN Government General, 1942-'Science Text for Elementary School'(Writing laterally) 1943-.
