The chemistry lessons often introduce the students to many terms and theories, but they tend to not understand the principles of the phenomena and actions such described, and they are not able to apply them when solving real situations. Inquiry-based education is one of the possibilities how to change this.
Its use in teaching depends on, among other things, preparation of suitable educational materials. Currently, there are many of them available, but they often lack suitable properties and aren't good enough for the classroom.
This contribution describes the basic steps necessary for development of inquiry-based teaching and learning units that fulfil the IBSE attributes, based on references and our own research work.
