Results and Discussion
The data were collected over several weeks, and each class needed three lessons, or
five to six hours to finish the sequence. In the lessons, most students had difficulty making
the motor (designing it rather than constructing it). Designing the motor means making it
using the rotor and wire, while constructing the motor means making it using the coil (pink
wire). Students needed 10 minutes to fill out the MCAI questionnaire because they needed
to think about their habits when they encounter a problem. The contents of the MCAI
questionnaire consisted of questions about habits during problem-solving activities.
