Languages of publication
The Model of Educational Reconstruction provides a frame for research of subject related learning and teaching. By closely linking theory and practice the model aims at the development of learning and teaching sequences. Within the framework of the model three central tasks of research in science education are investigated: firstly, the clarification and analysis of science subject matter (e.g. in the field of genetics), secondly, the investigation into students’ perspectives with regard to phenomena related to the chosen subject (e.g. conceptions, principles), thirdly, the design of learning environments (e.g. guidelines for teaching the subject, learning activities, lessons or learning sequences). The investigations are carried out empirically. But there is no way of solving these three modes of investigation as single tasks one by one. Each of the investigations depends on the findings of the other two; all of the tasks are interrelated and have to be linked closely. The model of educational reconstruction also guides the creative designing process and leads to empirically based proposals for teaching designs and to conclusions for learning biology. In the contribution the investigation in the field of genetics is exemplified, findings of students’ conceptions, guidelines for teaching and general educational conclusions are given. Furthermore, the application of the model in several places and disciplines is reported.
