TEORIA DOS CAMPOS CONCEITUAIS COMO INSTRUMENTO PARA O PLANEJAMENTO E CONSTRUÇÃO DE RECURSOS TECNOLÓGICOS PARA O ENSINO DE CIÊNCIAS.

This research examines the role of technological resources in lesson planning and teaching practices in the context of Vergnaud's Theory of Conceptual Fields. All the work on the lectures was carried out using App Inventor to create a mobile app for 9th Grade students (age 13-14). Students had to understand how the mobile application contributes to learning Archimedes' principle and then take part on a survey after been given the lecture on buyoant force. The survey was taken by 78 students from a public school, with a quantitative and qualitative approach to the case study. Following this, the analysis showed that the Theory of Conceptual Fields is a crucial reference of didactic planning and can be used to build technological resources that actively engage students throughout their learning process, because it supports the class environment in selecting concepts and key-theories and what correlates between them.
