These conceptions are being investigated across tasks with varying context. Participants were secondary education students in eighth, tenth and twelfth grades. Latent Class Analysis (LCA), a psychometric approach, was implemented to analyze a set of four tasks, in order to identify distinct mental models, which share specific sets of misconceptions. Furthermore, the detected mental models were associated with a number of external variables, such as the age, and the three cognitive variables: formal reasoning, field dependence-independence and divergent thinking. Results indicated that age and two cognitive variables under study had significant effects on students’ mental models. Implications for theory and practice are discussed.</p> ER -
