Abstract
At primary school, we decided to organize a project day focused on the environmental topic waste and the environment. The students participated in an intensive programme for one day.
During this day, they were drawn into the problem using several teaching methods (video, work with text, lecture with expert, chemistry experimental part or workshop). The teachers' aim of the project was mainly to assess the effectiveness of learning during this day.
We used three mind maps to find out the results. At first, the grade 9 students wrote their own mind map without any introduction to the specific issue.
Second mind map was made with the same classes immediately after the project day. Retention "testing" will be carried out with a time lag, which will take place one month after the implementation of the project day.
The retention "testing" will be made also via mind mapping. The data obtained from all the stages of the research will be evaluated and interpreted.
