Its great to see so many people using Construct 2 in the classroom!
I am a high school physics teacher in Illinois, USA. Until a few weeks ago when we discovered Construct 2, we had been using GameSalad as a modeling and simulation tool, which worked really well for our second-year physics students. A week and a half ago I gave Construct 2 to those students and tasked them with building a useful simulation for our iPad-based classes similar to those available at phet.colorado.edu. I will post the results of the challenge later this week.
I am curious to see lesson plans. In particular I am looking to use Construct 2 in two ways:
1. As a creative tool (e.g. create a short game to demonstrate an idea)
2. As a modeling and simulation tool (e.g. create a system of planets, modify the rules of gravity and see what happens)
My pipe dream is to use Construct 2 to develop a physics simulation creation tool that is simple enough for 10-year-olds with low math skills to use but is powerful enough to teach physics modeling to high school students. Maybe next summer. :)
