Introducción a la genética en la enseñanza secundaria y bachillerato: II. ¿Resolución de problemas o realización de ejercicios?

Abstract

In this paper we analize the level of knowledge students have at different educational levels (15-18 years), about some basic concepts related to genetic inheritance. The strategies developed by students when solving, successfully, genetic problems have also been studied.The results show the difficulties in learning through problem-solving activities. Consequently, very often, their posings (even those of cause-effect approach) allow them to find the right solution by applying the correspondent algorithm. As a conclusion, some suggestions to change the students’ position on genetic problems are presented.
