  • In the process of establishing the principle of genetics, Mendel discovered problems based on various observations. Mendel's scientific thinking ability can be effective if this ability is embedded in gifted science education programs. The study aims to develop a science gifted education program utilizing Mendel's scientific thinking ability shown in the principles of genetics and examine students' changes in scientific thinking ability before and after the program implementation. For the program development, first, the characteristics of Mendel's scientific thinking ability in the process of establishing the principle of genetics were investigated and extracted the major elements of inquiry. Second, the science gifted education programs was developed by applying the inquiry elements from the Mendel's Law. The program was implemented with 19 students of $7^{th}$, $8^{th}$ graders who attend the science gifted education center affiliated with university during July 2011. The Mendel's scientific thinking ability was classified into induction, deduction, and integration. The elements of inquiry extracted from the Mendel's scientific thinking include making observation, puzzling observation, proposing causal questions, generating hypothesis, drawing inference, designing experiment, gathering and analyzing data, drawing conclusions, and making generalization. With applying these elements, the program was developed with four phases: $1^{st}$ - problem finding; $2^{nd}$ - hypothesis generating; $3^{rs}$ - hypothesis testing and $4^{th}$ - problem solving. After implementation, students' changes in scientific thinking ability were measured. The findings from the study are as follows: First, students' abilities of problem finding is significantly (p<.05) increased. Second, students' abilities of hypothesis generating is significantly (pp<.05) increased.

  • The purpose of present study is to examine the science attitude level of middle school, high school and university students, and to provide the suggestions for science education. Instrument to invent science attitude consists of four domains as 'Scientific Inquiry', 'Importance of Contribution to Science', 'Normality of Scientist', and 'Social Value of Science'. Inventory instrument have 20 items(Likert scale of 1 to 5). Subjects are 70 middle school, 72 high school, and 95 university students. There is no significant difference among students by school, but the attitude level toward science of female students is lower than that of male students. 'Importance of Contribution to Science' among four domains has the highest score of attitude toward science, whereas 'Normality of Scientist' has the lowest attitude score toward science. To bring up scientific abilities of students, we conclude that it needs the educational plan to increase science attitude of students, through improving and developing curricular system and science curriculum for the secondary school and university.

  • It is important to know science terminology when learning science. In terms of linguistic and psychological perspectives, the context of encountering a terminology for the first time is critical. If a student has not learned the terminology properly the first time, it might cause misconceptions or be a barrier in following learning. This study aims to identify how careful science terminology are used in science textbooks, and the relationship of using science terminology between science curriculum and middle school science textbooks in the 2009 National Curriculum. In addition, the educational need, the importance of science learning, proper time for teaching, & difficulty of the terminologies have been surveyed among teachers and students. As results of study show, only 25% of terminologies in science textbooks have appeared in the curriculum, and about 10% have been used in middle school science textbooks prior to science curriculum. The survey results suggested that many of those terminologies could cause problems in teaching and learning situation. The solution for them have been divided into the following: avoiding usage in textbook prior to curriculum, using earlier in textbooks, using earlier in curriculum, and reflecting curriculum precisely in the textbook. In general, the curriculum needs to state performing objectives concretely. And it is needed to examine science terminology advertently when writing textbooks.

  • The relationships among students' perceptions of computerized science learning environments, computer-related attitudes. and computer experiences were investigated with a sample of 164 9thgraders (80 boys and 84 girls) from two middle schools. The Computerized Science Learning Environment Inventory (CSLEI) and the Computer-Related Attitudes Scale (CRAS) were administered, and students' computer experiences were examined. Students' perceptions of preferred learning environments were also studied with the preferred form of the CSLEI, and compared with those of actual learning environments. Gender differences in the perceptions of computerized science learning environments, computer-related attitudes, and computer experiences were also studied. Students' perceptions of preferred learning environments were significantly better than those of actual learning environments in all subscales of the CSLEI except gender equity. There was no gender difference in the perceptions of computerized science learning environments. However, boys were found to have more positive computer-related attitudes and more computer experiences than girls. Students' perceptions of computerized science learning environments were significantly correlated with computer-related attitudes in resource adequacy subscale, but not with computer experiences. Significant relationships between computer-related attitudes and computer experiences were also found.

  • In this study, the 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigation tasks can be characterized with practical context. openness and continuity. The purpose of this study is to describe the change of students' cognitive engagement while they perform the extended science investigations and to explore how the characteristics of the extended investigation tasks affect the students' cognitive engagement. 128 7th graders attending coeducational school in Seoul were participated in this study. The questionnaire was implemented repeatedly to monitor students' cognitive engagement. And ten students were interviewed to explore the cause of the change of cognitive engagement. The result showed that there was no difference between directive traditional investigations in textbook and developed extended investigations in understanding of the content and whole process of investigations but participants' commitment was increased significantly in the extended science investigations. Especially the extent of students' understanding and commitment became higher in the second half than in the first half of the extended science investigations. The openness of the extended investigation tasks contributed on the increase of commitment. And the continuity of the tasks contributed on the increase of students' understanding in the second half of the extended science investigations.
