Traditional models focus on teachers as being the sole providers of instruction.
The CLM argues that the aquistion of knowledge requires active participation. Students should observe and question topics that are of interest to them and then investigate those topics to construct their own understanding. By working in small groups, students share, critique, and defend their understandings. Not all students have a high enough motivational level to pursue their own inquiries with sufficient energy to really learn something. It would help to start off a class with structured activities so that the students could first learn the process of pursuing an inquiry.
