His lesson did not engage students with investigation (or
problem solving), and also did not provide an environment
where either students could challenge ideas or could pose
their questions. His class was very structured and teacher-led.
He demonstrated what students needed to do, and students
followed that step-by-step. Therefore, in his class, most of the
questions were basic recall of facts. Although he encouraged
students to explain how they solved the problem, students
were using the same procedures as he demonstrated to them.
