En el informe What Makes Great Teaching, se identifican las variables que, por estar bien soportadas en evidencias empíricas acumuladas, nos permiten asegurar que garantizan un aprendizaje de calidad. La más importante de todas es el dominio de la asignatura por parte del profesor:
The most effective teachers have deep knowledge of the subjects they teach, and when teachers’ knowledge falls below a certain level it is a significant impediment to students’ learning. As well as a strong understanding of the material being taught, teachers must also understand the ways students think about the content, be able to evaluate the thinking behind students’ own methods, and identify students’ common misconceptions.
Esto, que es tan obvio, es precisamente lo que hoy es de buen tono pedagógico cuestionar entre nuestros pedagogos. A mi me parece desolador.
