This study provides evidence of the effect of video analysis of real classroom situations as a support for promoting the professional vision among primary education pre-service teachers. Specifically, it focuses on the Science Process Skills involved in scientific inquiry when teaching through this method. This quasi-experimental study (n = 90) analyzes a didactic strategy based on the noticing and coding of inquiry teaching practices in school contexts. It aims to encourage pre-service teachers' knowledge of the Science Process Skills. The quantitative results show a significant improvement in all these skills in the experimental group, mainly with regard to the proficiency of "Planning and Experimentation" and "Interpretation" skills. These data are congruent with the results obtained from the qualitative analysis of the codification engaged in by this group. The results of this study contribute to responding to the need for resources in the scientific inquiry education of pre-service teachers in primary education. Video analysis was observed to help mobilize a wide range of concepts involving knowledge of the Science Process Skills that are studied in the initial stages of teacher education.
