Facilitare l'insegnamento della teoria dell'evoluzione. Una risorsa utile per il CLIL di Scienze in inglese


red - Gergely KERTÉSZ e Violetta LENÉR hanno strutturato un modulo con l'intenzione di far comprendere meglio gli argomenti relativi alla discendenza comune delle specie, mettendo in evidenza alcuni fatti epistemologicamente rilevanti. Nel modulo vengono riportati esempi e narrazioni tratte dalla storia della biologia, facendo incursioni nel mondo della filosofia della scienza.

Nell'abstract della risorsa leggiamo: "The module is designed for four lessons (4x45 min).

As opposed to prevailing textbook practice the module attempts to incorporate epistemic issues and some basic NOS (Nature of Science) issues into the teaching of evidences for evolution. Because in the last decade evolutionary theory faces new attempts of invalidation by different religious and antiscientific groups and surveys on scientific literacy have shown that much of what students and the lay public know about evolution is erroneous or full of misunderstandings, finding more efficient ways of teaching it became vital. To be able to realize a conceptual change strategy in teaching evolution the module relies on prior student knowledge and intuitions as resources for a more effective approach.

In traditional biology curricula, evidences for evolution are usually presented as a list of items to be studied and no explanation is provided on the relation between the theory and the facts. This statement not only true in Hungary, but it befits the traditional textbook practice of Anglo-Saxon countries. This kind of treatment results in a shallow understanding of the theory itself and the reasons behind its acceptance.

This module attempts to reach a clearer and deeper understanding of the classical arguments for common descent by highlighting some epistemologically important relations between facts and theories in the discussion of the topic. Examples and narratives from the history of biology and perspectives form the philosophy of science are used to achieve this goal. One novelty of the module is that it focuses on the less discussed theory of common descent as a basic component of evolutionary theory. Another is the use of the original Darwinian or Whewellian way of argumentation for evolution, the so called consilience of inductions. In most textbooks, the evidences for evolution are simply listed as equally important and independent facts in support of evolutionary theory. In the present module through the historical discussion of biological theorising the relations and the importance of the different facts is also clarified. 

The module is still under evaluation. The present results can only be evaluated in a qualitative way."
