Abstrakt
In this study, we focused on students' intrinsic motivation towards practical work, more specifically the strength of predictors for intrinsic motivation. As a research tool, we used a modified Intrinsic Motivation Inventory supplemented by additional questions on attitudes towards physics.
The respondents were more than 2000 Czech upper secondary students who had visited the Interactive Physics Laboratory (a lab offering hands-on experimenting for school groups). Using structural equation modelling, the data were examined with respect to the gender of the respondents, their intention to study STEM and their diligence in physics.
For all three criteria mentioned, the perceived value and usefulness of activity emerge as the strongest predictor of intrinsic motivation, followed by effort invested into experimenting. The issue of effort is more strongly addressed by students who feel less diligent in physics and do not plan to study STEM.
Both the students' perceived competence and felt pressure have a rather marginal influence on intrinsic motivation. Though the strength of predictors of intrinsic motivation is gender-similar, we found boys feel more competent and less stressed when experimenting.
Further, diligent students and those who intend to study STEM feel more competent, perceive greater usefulness and feel less pressure during practical work.
