Figure 6. — Content analysis of student models of meiosis in the Cell Biology class. A total of 14 groups of five to six students were given 30–40 min to construct and explain a model of meiosis using manipulative materials. Their explanations were videotaped and analyzed for content. Blue bars indicate elements that demonstrate an understanding of the molecular structure/behavior of chromosomes; orange bars indicate elements that do not rely on a solid understanding of the relationship between DNA and chromosomes.
