In my opinion a successful science classroom is one where students are engaged, working in groups and active in their own learning. I like to have the students 'run the show' so to speak, where they know where they make a plan, get materials, build and then test, discuss and retest.
The same would be true for them to create their own computer models. We create conceptual models and then physical models but not with the computers. I am excited to start using computers to create the physical model as well.
Teachers then roam around the room engaging with the groups of students about their projects then a group discussion happens where groups demonstrate their models with the class as well.
Organized Chaos is what the group work usually looks like.
