An audiovisual (video) teaching unit on the chemical laboratory technique 'recrystallisation' was developed along problem-solving rather than didactic lines, on the basis of observation and analysis of student behaviour in the laboratory. The research indicates that, in determining the content of a teaching unit, it may sometimes be very sensible to ignore the opinions of specialists (the teachers), who may wish merely to present a unique ideal method' for a technique, without making clear the reasons for certain steps in the prescribed procedure. It is important for students to learn from which viewpoints decisions were made in the development of a chemical procedure. In the teaching unit devised, students are challenged to discover their own method, guided step by step through the conflicting opinions of teaching assistants and fellow students.
