Abstract
The purpose of this study is to demonstrate the efficacy of students solving science problems involving amounts per unit while guiding them to pay enhanced attention to units and the results of their abilities to solve science problems, regardless of the presence of such units in examination questions.
The results of the study reveals the following:
1) Students improved not only in solving science problems on amounts per unit but also in being able to solve other science problems they had not studied, by guiding students to pay enhanced attention to units.
2) In general, it is important to comprehend the meaning of units in order to understand science concepts. Teachers must guide students to pay enhanced attention to unit dimensions and comprehend the meaning of units so that they are able to solve science problems more easily.
Therefore, it is essential for teachers to instruct students more carefully on units.
