Abstract
The purpose of this study is to examine the effect of PBL-based astronomical observation on the science process skills and scientific attitudes in elementary science-gifted students. To verify research problems, the subjects of this study were forth-grade students selected from one classes of an elementary science-gifted class in Busan National University of education : the research group is composed of twenty students who were participated in PBL-based astronomical observation program. During four weeks, the PBL-based astronomical observation program instruction was executed in the reasearch group. Post-test showed following results: First, the research group showed a significant improvement in the science process skill. We look into detailly this, the research group showed a significant improvement in the basis science skill. The sub-factor 'expectation' of the science process skill effects a significant improvement. Second, the research group showed a significant improvement in the scientific attitudes. In conclusion, PBL-based astronomical observation program was more effective on science process skill and scientific attitudes. However, since the study has a limit on an object of the study and the applied program, the additional studies need to be conducted with an extended comparative group and program.
