Modelos y analogías en la enseñanza de las ciencias naturales. El concepto de modelo didáctico analógico

摘要

In this paper scientific models are examined with a representational and linguistic perspective. Some didactical models are considered as raw simplifications of the original scientific models, acritically brought into the classroom. Finally, we define and exemplify the concept of didactical analogical model. Our hypothesis distinguishes between experts (teachers) and novices (students) in terms of the richness and fluency of the families of models that they use.
