Abstract. The possibilities of students learning ecology by means of developing projects based on ecological observations and experiments in nature were studied. The constructivists’ concepts were analyzed as well as the criticism of their opponents in order to determine the theoretical framework of the teaching model. The achievements of students in two variations of teaching were compared: Experimental (E) – team work in doing chemical, physical and biological experiments in the ecosystems, analyzing and presenting data with the aid of ICT at a school conference; Control teaching (K) – visualized with the aid of ICT lectures, delivered by the teacher, construction of conceptual maps by students. Special attention was paid on discovering and solving environmental problems. Student’s achievements were evaluated by means of tests for knowledge, diagnostic observations for skills and questionnaire for attitude towards the new ecological paradigm.
