Activity orientation in chemistry lessons You want to train both content-related and methodological learning objectives in chemistry lessons at secondary level I? This volume provides you with learning circles on the periodic table and atomic model that promote independent learning for each individual student. Periodic Table and Atomic Model learning at stations The students work independently on a wide range of tasks related to the periodic table and the atomic model. In doing so, they proceed completely independently and work at their own pace. This means that differentiation within the learning group is no problem if there are different levels of achievement. Sustainable learning in the subject of chemistry Students learn in a particularly sustainable way when they work independently on the learning content. The learning circle can be used immediately in class without much preparation. Si.
