Presents and discusses results of a project that studied the effectiveness of concept and Vee mapping strategies in helping Black inner-city high school students (N=250) learn biology concepts meaningfully. The project sought to assess effects on achievement of the two methods as part of a carefully designed sequence of instruction. (Author/JN)

An investigation of students understandings of acids and bases using concept maps, multiple-choice tests, and clinical interviews is described. The methodology and resulting analysis are illustrated with two abbreviated case studies selected from the study. Discussion of concept mapping points to how it starkly represents gaps in the understanding…

Within high school chemistry the topic of acids, bases, and pH is particularly challenging because robust understanding of the topic depends heavily on the student possessing deep concepts of atoms, molecules, ions, and chemical reactions. Since knowledge is acquired and stored in a dynamic structure, it was investigated in this study how…
