What they have learnt is quite encouraging. For once David was awake till 12:30 a.m trying to develop something. He wasn’t successful, but I noticed he wasn’t demoralized and the next morning he continued. Derrick enjoys it and even prepared a presentation on powerpoint to explain what he has done. I wish they can continue, though not sure on balancing with everyday school work. They still have a very long way to go. But I am sure their holidays wiill always include programming, until they get a good hands on. Well done and keep improving your interaction strategies.
