La digestión de los alimentos: un plan de actuación en el aula fundamentado en una secuencia constructivista del aprendizaje

Resumen

Nowadays constructivism seems to be quite a sound approach on which to base the processes of teaching and learning sciences. Assuming the basic hypothesis of this theory, sequences of instruction can be designed that help to improve the work that both, teachers and students carry out. In this paper we put forward a plan based on a constructivist approach, developed in secondary classrooms (13-14 years of age) about digestion, which is flexible enough to be adapted to different circumstances in which the learning of sciences takes place.
