3.4 Data Collection
For investigating students' physics motivation in whether they perform inquiry-based learning process
with a blended combination of hands-on microcomputer-based laboratory and computer-simulated
laboratory on sound wave phenomena. The study participants were asked to response the 25-item
5-point Likert-scale questionnaire for 10 minutes at both before and after interacting with the
blended lab. On each item, respondents were assigned to rate how much the respondent agree with into
five scale, from 1-strongly disagree to 5-strongly agree. In the blended lab class, both groups
participated physics learning of sound wave through inquiry-based learning process for 480 minutes.
Figure 1 and 2 illustrate example of blended lab activity for physics learning of sound wave.
