Within science education and research it is well-known that students´ understanding of the concept of matter is crucial for their further understanding of a range of science phenomena. In an ongoing research project, funded by the Swedish Research Council, it is investigated how teachers´ professional learning develops as a shared practise. In three learning study cycles five science teachers explored the concept of matter as a prerequisite of understanding e.g. chemical solutions and photosynthesis. Students’ tests, video recorded lessons and discussions, served as instruments for the teachers in their investigations. The researcher used the same data sources together with teacher interviews when analysing the character of the findings made by the teachers. Variation theory served as a tool for the teachers´ common knowledge development. The teachers developed their ability to point out critical aspects, identify necessary conditions for students´ learning and enact their produced knowledge in teaching situations. It was found that it is crucial to point out what matter is not, i.e. to create a contrast to the concept of energy. Another finding was the importance of pointing out the empty space between atoms and molecules, something that was made possible for the students to discern through contrasting the view of matter as homogenous with the non-homogenous view of it. The significance of keeping the critical aspects in mind in the dialogue with the students was emphasized as to pay attention to the language used. It became evident what critical features which were important to pay attention to and how this could be done in practice. It was also concluded that the teachers´ experiences might improve students´ learning of other objects of learning as a result of the teachers´ professional development.
