Both methods require students to understand the relationships among items and to be actively involved in learning. TAAS includes both kinds of experiences.
Students examine sets of data and materials.
With teacher, they identify and explain key points through questions and discussion, observing similarities and differences, patterns, and trends in the data and materials. Finally, students draw conclusions from the data, summarize their findings, and discover or infer the generalization. Students are presented with a hypothesis-a potential generalization. Or students are given a generalization and asked to find evidence to support it. The key concepts that are components of the generalization are clarified.
