Guthrie, Janice M. – 1991
The concept of the mole and its relationship to chemical algebra is difficult for many high school chemistry students to master. This paper describes a study of the use of proportional reasoning when teaching mole relationships and its effect on developing critical thinking skills. The Test of Logical Thinking (TOLT) was used as a pre- and…
