Last class period we went to visit a 4th grade class to teach about light refelectivity. Each studnet had designed a worksheet and short lesson plan for a group of 4-6 students. Overall we had a great time with these students. Some common things that we (as a class) observed were:
the 4th graders knew more that anticipated
it's better to not lead the students through the activity but allow them to lead their own learning
don't directly anser the students questions but explore the question as a group
allow each student to say what they think and the knowledge they know, don't let the shy one be left behind
