A way of working that supports the development of content understanding, conceptual knowledge and thinking skills through problem solving and interaction.

Through this web resource, mainly based on video recordings in authentic classroom situations, teachers can explore how open-ended investigations and V diagrams can be successfully used in chemistry education. The resource also provides guidelines for how the learning of students with a non-mainstream background can be supported.
