The paper presented summarises the most important principles of problem - based teaching realised through problem - based tasks. A basis of the research, carried out in this area, are problem – based tasks from science subjects – mainly from biology and chemistry – for pupils of elementary schools and students of secondary schools. Solutions to these problems are presented as models realised through a problem- based programme expressed by a flow chart. This chart - designated for teachers - represents a design of micro-regulation that expresses a supposed structure of thinking activities of students and controlling activities of teachers in search for solutions to the respective problem - based tasks. The use of the programme in the teaching process widens a scope of individualised activities of teachers. Within this research, 148 problem – based tasks have been gradually developed. In experimental classes of the eight and ninth grade of elementary schools and in the first and second year of secondary schools, practical verification of these tasks have been carried out. The most significant outputs of the research are referred to in the conclusion to this paper.
