Keywords:
Chemistry Teacher Education; Time; VisualizationAbstract
This exploratory study investigated the relationships between time and the use of visual resources, supported by audiovisual records of the practices of pre-service chemistry teachers applying Teaching-Learning Sequences. The content analysis was based on analytical categories found in the scientific literature. The results showed a positive correlation between increased time spent using visualizations, diversification of the students’ actions, and the quality of the students’ verbal interactions, through the predominance of conceptualizations in the submicro domain, with transitions between the macro and submicro domains. Thus, this study reinforces the importance of reflecting on the different ways of using visualizations in classroom time during the chemistry teacher education, and the importance of building a vision of the field of studies on visualizations that is thoroughly integrated into the school curriculum.
