  • In this study, the characteristics of science inquiry problem solving were analyzed in the interactions between science process skills and science concepts by each related its category. Nine types of problem solving, which were based on two elements and the thinking aloud were found largely by protocol analysis, but six types when integrated similar thinking processes. There were quite differences in the representative types between students who succeeded and failed when science inquiry items were solved in the abilities of recognizing problems and generating hypotheses or those of drawing conclusions and evaluating. But there were not complete differences in those types between students who succeeded and failed when they were solved in the abilities of designing and performing experiments or those of interpreting and analyzing data. The data were divided into independent variables: $D_1,\;D_2,\;D_3,\;D_4,\;D$ and $C_1,\;C_2,\;C_3,\;C_4,\;C$ and dependant variables; $E_1,\;E_2,\;E_3,\;E_4,\;E$. The former consisted of the content-free science process skill achievement levels by each category of science inquiry skill and the science concept achievement levels, the latter the science inquiry problem achievement levels by each category of science inquiry skill. The regression equations were acquired within the 0.05 significant level by regression analysis: $E_1=0.03+0.16D_1+0.29C_1,\;E_2=-0.203+0.21D_2+0.45C_2,\;E_3=-0.32+0.13D_3+0.47C_3,\;E_4=0.61+0.09D_4+0.29C_4,\;E=-1.41+0.13D+0.47C$(E : the achievement of science problems, D : the achievement of science process skills, C : the achievement of science concepts).

  • The purpose of this study was to investigate how 'free inquiry' was implemented in middle school science classrooms. In order to do this, survey and interviews were administered. The subject of survey was 165 science teachers at 58 middle schools and interviewees were 4 teachers and 10 students. As a result, 49.6% of science teachers in school year 2010, and 34.1% in 2011 applied 'free inquiry'. Teachers applied 'free inquiry' during one semester, and they let the students select topic of 'free inquiry'. Teachers grouped students according to students' opinion or their gender and ability, and one group was consisted of 4 students. The effect of applying 'free inquiry' was that students improved the interest on science, science inquiry ability and self directed learning capability. Students were interested in doing 'free inquiry', and they wanted to do it again. Teachers claimed that it took much time and effort to apply 'free inquiry', and students lacked science inquiry skills and interest on science. The teachers who did not apply 'free inquiry' stated reasons such as the shortage of instructional time, and they didn't think that 'free inquiry' should be implemented. For the effective implementation of 'free inquiry', this study suggested that teachers should be recognized the intention of 'free inquiry', teaching-learning materials about 'free inquiry' be developed and provided, and laboratory assistants be employed.

  • The purpose of the study is to investigate the applicability of portfolio assessment to ordinary elementary science classes, and the effects of a portrolio assessment on students' science achievement, inquiry ability, and science attiudes. Two schools were sampled from a metropolitan area, a city, and three schools from rural area in central Korea. Two fifth-grade classes were sampled from each school selected, and one class is assigned to experimental group and the other to control group, respectively. The total number of participants of the study are 475. Portfolio assessmest was administered to experimental group, and conventional teaching to control group for two and half month. Science achievement test, science inquiry ability test, and science attitudes test were administered as a pre- and post-test. Portfolio asseddment seems to be applecable to ordinary elementary science classroom. Statistically meaningful difference was not found in students' science achievemant by group, region, and sex. Students' inquiry ability and science attitudes showed statistically meaningful difference by region rather than group. Experimental group showed more positive scores on some sub-domains of science attitudes, such as perception on science education, and science career, interests in science activity, and criticism. In conclusion, portfolio assessment can be applicable to ordinary dldmentary science classrooms. The effects of portfolio assessment are at least the same as the traditional teaching on student science achievement, inquiry ability, and science attitudes.

  • The purpose of this study is to inquire the properties and relationship of attitudes toward science and process skills of preservice elementary teachers. Two instruments were used to collect the data, SAS(Science Attitude Scales) for checking up attitude toward science and TIPS II(Test of Integrated Process Skill II) for inspecting science process skills. Three main results were revealed. First, preservice elementary teachers' the attitude toward science and science process skills could not show the significant differences by gender. This result is differ from the results of preceding researches which had set up the students of elementary, middle and high school as objects. Second, the properties of preservice elementary teachers' the attitude toward science and science process skills according to the course in high school were also differ from those of preceding researches having students as objects. The preservice elementary teachers who got the literary courses in high school were more confident in science learning and perform that those who have the academic background of science courses in high school. In addition, although they showed better abilities in two sub-scales of science process skills, the preservice teachers with science course didn't show the better science process skills than those who had taken the literary course in total score of science process skill test. Third, there was a significant relationship between attitude toward science and science process skills of preservice elementary teachers but just one sub-scale was related with science process skills. According to these results, it can be said that the preceding results with students as objects can not be applied to and preservice elementary teachers should be guided by the methods which are considering their special properties.

  • The purpose of this study was to develop an inquiry-based professional development program for in-service secondary science teachers and to investigate it's application. The inquiry-based professional development program was reconstructed based on SSCS problem-solving model, which is composed of 4 stages of search, solve, create, and share. The 28 science teachers' understanding of the SSCS program were investigated as implementing the program. As a result of this study, 8 SSCS modules have developed as the science teachers have searched, solved, created, and shared various situated problems. The science teachers found themselves to have positive perception of SSCS program. The SSCS program was effective in changing the learners' teaching/learning attitude and to develop individual scientific thinking. To make the SSCS problem solving successful and more effective, both science teachers' professionalism and pedagogical knowledge for selecting topic as the levels of learner should be considered.

  • This study was to analyze science process skills related to 'state of matter' and 'state change of matter' in the kindergarten, elementary and middle school science textbooks. On the base of articulation, we analyzed science textbooks of the 5th kindergarten curriculum, the 6th elementary school science curriculum and the 6th middle school science curriculum. The findings indicated that the scientific inquiry abilities of predicting, classifying, hypothesizing and designing investigations are not enough in all grade science textbooks. Also, while young children have measuring ability theoretically, it was represented only in high grade textbooks. We concluded that these were inappropriate from the viewpoint of articulation which is related to scientific inquiry ability.
