Wolfe, Drew H.; Heikkinen, Henry W. – Journal of Chemical Education, 1978
Evaluates college students' understanding of chemistry as operationally defined by Bloom. The Test of Higher Cognitive Learning in Chemistry was administered to 488 students upon completion of a one-semester course in general chemistry. Significant differences were found among student mean scores at various cognitive levels. (HM)
