Figure 2: Relationship between teacher questions and student responses. Evolutionary tree diagram describing the relationship between teacher questions and student responses.
The oval nodes 1, 2, & 5 and the branches in the upper part represent qualities of teacher questions following the coding schemes in table 1. Nodes 3, 4, 6, & 7 represent types of student responses following a teacher question. The prevalence, in percentages, is displayed in the boxes at the bottom: dark grey = reproductive student answers, middle grey = elaborative student answers, light grey = no student response. On top of nodes 3, 4, 6, & 7, the absolute number of cases is reported, which were considered in establishing the respective category.
