This past summer, I introduced these Ozobots to my young campers (ages 7 – 10). They were excited at the idea that this little robot would follow a hand-drawn line. There’s something about combining “high tech” and “low tech” that they find baffling – and that instantly draws them in. They know markers. They’ve been working with them for years, so the barrier to entry is very low. It’s the perfect way to introduce them to these tiny bots and to enforce (or introduce) the idea of computer languages.
While I think computer programming is a great skill to have (or at least be aware) for this next generation of children, I place a greater value on being creative and persistent. These little bots can encompass both of these skills. As I’ve said before, the paper and marker language is not always consistent and thus, children (and adults) need to have some grit to be able to solve their problems. Sometimes the bots need to be re-calibrated, sometimes the marker line is too thin, etc.
So, how to help them move forward after the initial play period has worn off? Maps.
Once they understand how the Ozobots work and how they read their color-coded computer language, I asked my students to create a map of places for their little bot to visit. The instructions were open-ended, but I ended up asking lots of questions about their favorite places to visit. The task seemed a bit overwhelming at first, but after asking them to draw one place that they would love to visit, they took off.
There was a lot of giggling and hastily-drawn buildings as the Ozobot would randomly choose paths to take. Some of the students had deliberately added lots of fast food restaurants to their map and they were delighted when the Ozobot would “eat out” way too much. It prompted an additional doctor’s office and hospital on the hand-drawn maps. What a fun way to teach the concept of moderation.
Each student’s map was different and they varied based on age, ability and interest level. For some of the younger, “less-art” kids, I sat with them and helped them to stay on task – asking questions and wondering where their Ozobot might want to go next. Did they like to visit the beach? Would they like to find work as a tractor on the farm? Maybe they wanted to visit a friend’s house?
In addition to helping them develop their creative muscles, this activity also helped students to see various paths to creating. Would they choose to create the Ozobot’s path first…with various color codes? Or, would they want to create places to visit first…and then add a path later? The decision-making was sometimes intense and there were lots of opportunities to think about how to plan out (or not) their Ozo-village. None of the children I worked with suggested using a pencil first, but this might be a great concept to introduce to an older crowd. Either way, they had fun, they learned something and hopefully, they feel confident knowing how a line-following robot works.
