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

Resum

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.
