La representación del tiempo histórico en los libros de texto de primero y segundo de la enseñanza secundaria obligatoria

The article is a summary of the doctoral thesis carried out by Angel Blanco and directed by Joaquin Prats, entitled «How Is Historical Time Represented in Text Books in 1st and 2nd Grades of ESO (Compulsory Secondary Education)». The main aim of the research was to observe which transfer processes and means are used by handbooks to represent historical time. To do so, eight Social Sciences text books of first and second of ESO were selected, then the authors studied, following a specific model of analysis, the concepts developed in the contents and resources, their degree of difficulty and the rate between both groups. They also checked to teach historical temporality and the processes to adapt to the age and level of the pupils.
