It’s amazing to see the affordances that technology offers these days, I hope teachers would not forget to explain or at least shed a bit of light on the concept of simulation that underpins these tools. We don’t want to see a politician or urban planner some 10 to 20 years down the track, making critical decision based on their ‘simulated’ experience naively think that the programmed algorithm under the hood of the simulation tool equal to facts of natural phenomena. Proper explanation about what is the meaning of assumption and how things might be different in reality compared to simulated world could be very crucial.
