Participants were th graders. This study adopted a quasiexperimental research design in which experimental group was taught with 3D planetarium software vs. control group with traditional lecture-centered teaching method for 6 hours. The effects were investigated by independent sample t-test and paired sample t-test The results are as follows. The instruction using 3D planetarium software was more effective than the traditional lecture-centered curriculum in science achievement and self-directed learning ability.however, there were not meaningful differences in analyzing attitudes related science, the results that were so effective in elevation for self-directed learning could be gained. Students were interested in instruction applying 3D planetarium software, which was helpful for them to understand the content knowledge. Results showed that instruction with 3D planetarium software applied was effective in 8 th grade science learning.,fzxpset Earth and Star, Science Instructions, 3D planetarium software : w 2w w w 3D v (Starry Night pro 6.0) y w w z w w, w k,» w e w w w z w. w 2w 198 w 6 3D v (Starry Night pro 6.0) y w w z w» z mw w z w. t t- t t- w w., 3D v y w m w w z ƒ ùkû (p<.05). ù 3D v y w w k e z w z ƒ ùkû (p>.05),» w w z (p<.05). 3D planetarium software y w 8w w z. š ó eš., w w, 3D v k vp w w w ù x w w *Corresponding author: kookds@chungbuk.ac.kr *Tel: *Fax: y š, w y y ƒ w š w. ù Áœ w x ù w y w w (, 1999). wš xw w w w z»
