Introduction. The mole concept is an abstract, complex, and quantitative concept that is central to the high school chemistry curriculum. Research has shown that high school students find the mole concept to be one of the most difficult concepts encountered in school. One reason for this difficulty may be that the mole concept is abstract while the intellectual ability of many students may be more concrete in nature. In recent years concrete instructional methods have been advocated to enable learners to master abstract science concepts. However, this approach has not appreciably helped the concrete operational student. In addition to the concrete instructional technique, many additional strategies may be necessary to maximize achievement of concrete operational students on abstract concepts. [...]
