There are many different pages on the internet for making a concept map. I have also tested parts with my students and found environments – which they like and which they don’t.
www.bubbl.us turned out to be the most convenient environment for me and the children
In the first informatics lesson, we made a concept map with the 6th and 7th grades. Making the concept map wasn’t difficult for them, but the download part was a bit confusing. But downloading is actually easy:
You have to press the download button indicated by the red circle in the right corner and choose the format of the concept map you want (generally, the images have a JPG file extension).
The download will then take place automatically (usually the downloads will go to the new-mind-map.jpg folder on the computer automatically).
