ConceptCraft is with which I as chemistry teacher display my ideas and prjects. I'm also teacher in the subject Research & Development and initiatief projects like ICT & Development and Robotics. I like education styles as we can see in The Netherlands (Agora style education) and High Tech High (San Diego) style education.




For my chemistry students I made an app to show them what an atom looks like in 3d. It’s an atom simulation of sorts. It’s called atom.sim. It’s available for Android and iOS.

AtomApp (or Atom.Sim) is nothing more than a simulation. It shows the first 18 atoms (up to argon) and the 3 isotopes of hydrogen in 3d models. Yoe can zoom in/out and rotate the atoms, you can use the slider to select another atom and you can switch written info about the atoms on and off. Also you can switch to the Real(ish) mode so can see just how empty an atom is.

The app has a small build-in help section (the ? button). It also has a banner ad section at the bottom. It is actually at a great spot. The chance of accidentally hitting the ad is very small.

Since the app is pretty straight forward in use I have no dedicated customer support section. The app and ConceptCraft uses no login and stores no information about any user. The ad provider might store info but that is beyond the influence of ConceptCraft. If there are question about the ap, please leave them on this page.

Now there’s a second app for chemistry students. It’s name is “Chemistry: practicing formulas and names” (Play Sore & App Store). The app can be set to English or Dutch language. Other languages will be added in the future.

This app can be used to practice making formulas and names for salts and molecules.

You don’t need any inlog or provide any personal data to use this app. There are ads in the app.


This section displays my ideas about education.

Content to be added soon.


As a teacher I initiate new projects.

ICT & Development is one of those projects. More and more students are interested in learning how to code. I challenge them to write down and draw their ideas, share them with friends and start developing. I invite them too use Unity, but many are using Scratch or Python which is absolutely OK! Results are not super great but we do see an increase in young students who are interested in coding, boys and girls. The older kids we see more students who are known to be interested in coding participating in coding and hack-a-thons.

FTC Robotics. Inspired by successes from other schools we participated in the FTC Challenge for the first time this year. We succeeded in getting into the Dutch National FTC Championships. Not bad for a rookie team 🙂 Through our local government we got money to improve our robotics skills so next year we will participate with two teams.
