The framework and its implementation of learning by doing design was described on the previous pages, but how can you make this interactive? And why should you use tools to make it interactive? What are the benefits in comparison to making the learner sending in written solutions in a word-file?

In the following pages essay tools, documentation tools and simple simulations will be analysed, while chapter 3 will be directed on gamification. There are a lot more tools that can be used for this purpose, but let’s keep it simple for now.
