Answer: d
Explanation:
he purpose of this research was to investigate the impact of engineering design classroom activities on middleâschool studentsâ conceptions of heat transfer and thermal energy. One eighthâgrade physical science teacher and the students in three of her classes participated in this mixedâmethods investigation. One class served as the control receiving the teacherâs typical instruction. Students in a second class had the same learning objectives, but were taught science through an engineering design curriculum that included demonstrations targeting specific alternative conceptions about heat transfer and thermal energy. A third class also used the engineering design
