With this research we hope to provide evidence on how to produce significant progress in prospective primary teachers' didactic knowledge when one works using resources based on inquiry into relevant professional problems and on interaction with innovative teaching practice. Furthermore, we aim to contribute to the development of resources and techniques for teacher education research, especially regarding the analysis of prospective teachers' production and the determination of the Itineraries of Progression that can act as hypotheses for future studies.
The work done so far has shown the richness in the opportunities offered by the creation of classroom videos. The details that need to be considered in their creation include the aspects that should be selected from the classroom activities, and the relative weights to give to the pupils' verbal and non-verbal communication, in particular, their gestures, silences, and facial expressions in the different classroom situations.
The present research is targeted at benefiting the training of primary teachers and, above all, at the relationship with primary schools. One expected benefit is the creation of new training resources (the prospective teacher's workbook and the classroom videos) which, in this case, are focused on school-research-based science teaching.
The work done so far has shown us the potential of the teacher training opportunities offered by the elaboration of classroom videos. We believe that the use of these videos will enrich the prospective teachers' teaching proposals. It will allow them to compare their ideas with real practice, and then to reflect on and analyse that comparison. Moreover, exercises with images captured from the videos will encourage their participation free from the corseting of academic discourse (Ezquerra, 2004, 2008). However, one will have to bear in mind that even a single image, and more so a sequence of images, shows so much information that it can distract or hinder the assimilation of the information that is really relevant. What the individual usually does is select only what is important to them (Soler, 2002). In other words: "In the perception we see a confirmation of reality, and at the same time of ourselves" (Doelker, 1982). Therefore, trying to determine which aspects are most attractive to our students might be an interesting starting point from which to attempt to discover what they see and what goes unnoticed,
what is important to them and what is ignored, on what to insist, and how to provide them with tools with which to analyse the reality of the classroom.
We also intend to try to improve the quality of our own actions as teacher trainers using these resources, the aim being to foster the development of our prospective teachers' knowledge about teaching. Furthermore, the fact ofhaving worked together with the primary schools is a reflection of the growing interest in collaboration between different fields and institutions in education (academic and vocational) to improve science education for primary pupils, an approach endorsed by the European Higher Education Area.
