CONCLUSION
The major findings in this study are summarized as follows. (1) Content achievement test scores
analyzed by ANCOVA indicated that students from the experimental group demonstrated significant
improvement in understanding the concept of electric circuits compared with those from the control group.
(2) Scientific attitude results examined by ANCOVA revealed that after experiencing computer
project-based learning, students were apparently more positive in their scientific attitude than those from
the control group. (3) During the processes of the computer project-based learning, the learning feedback
from the experimental group indicated that most of students in the experimental group had positive
responses to computer project-based learning. In view of the above findings, this study concluded that
computer project-based learning is effective for fourth graders.
