The total of 66 students-respondents in their eleventh grade (16-17 years old) were recruited in this
present study. They were divided into two experimental groups which received different learning
process in blended combination of hands-on microcomputer-based laboratory and
computer-simulated laboratory: open-inquiry laboratory learning (N=31) and guided-inquiry
laboratory learning (N=35) groups. Both groups were assigned to learn a physics lesson on sound wave.
The researchers conducted an informal interview with physics teacher in two regular classes, and the
results showed that all of students have basic skills on using computer. However, all of them have never
experience yet using hands-on microcomputer-based laboratory and computer-simulated
laboratory in physics class.
