Abstract

In order to affirm the characteristics of efficient professional training of teachers in the natural sciences, on the basis of a systematic overview of the literature, we chose and implemented an analysis of nine efficient experimental and quasi-experimental research designs. We affirmed that professional training should begin with initial workshops, which should continue through meetings of learning cummunities during these changes. Additionally, it is important to ensure support and guidance for teachers, as well as teaching materials for teachers and students. Professional training can be considered efficient only if it contributes to improved academic performance; this can be attained through changes in teaching, which should be founded on clearly established goals in accordance with which teachers may prepare teaching activities that inspire students to research, solve everyday problems, take part in active and cooperative learning, and think scientifically and metacognitively.
