Generally, students gave higher ratings to Question 4 (“Once a result is obtained, I
check to see that it agrees with what I expected”). This means that students wanted to try
again if the result did not satisfy them. This evidence correlates with process learning in
STEM lessons. When students designed the motor successfully, but the car did not move or
ran slowly on the circuit, they tried to identify the failure and wanted to try to improve
performances. Moreover, students change the goal of manufacturing a motor after they got
other problems (consume more energy, overheat, and go out from circuit). Students
redesign the fast motor to be safety motor using thinner wire. In these activities, students
were recognized that thicker wire makes motor run rapidly, so they were used thin wire to
solve generated problems.
