A pesquisa, conduzida segundo os critérios da grounded theory, foi realizada com doze participantes do terceiro ano de uma escola pública de Minas Gerais. A coleta e a análise dos dados tiveram como foco os conceitos de área de figuras planas e de volume de sólidos. O estudo descreve as percepções e concepções dos participantes em relação aos conceitos geométricos supra-referidos e à abordagem metodológica utilizada, e sugere que o ludismo, a interação, a contextualização, a etimologia, a qualidade de imagem e som, a concisão e a clareza são os principais elementos a serem observados em vídeoproduções com objetivos similares ao investigado. A pesquisa destaca ainda o papel significativo da manipulação de materiais concretos pelos participantes, assim como o papel mediador do professor, ao longo de todo o processo instrucional. / In this work we investigate the possibilities and limitations arising from the integrated use of educational videos and manipulation of concrete materials in high school geometry. The research was conducted, according to the grounded theory method, with twelve third-year high school participants from a public school of Minas Gerais, Brazil. The data collection and analysis focused on the concept of area of plane figures and on the concept of volume of solids. The study describes the perceptions and conceptions of the participants in relation to the aforementioned geometric concepts as well as to the methodological approach, and suggests that ludic dimension, interaction, context, etymology, image and sound quality, conciseness and clarity are the main elements to be observed in video productions addressing similar goals. The research also highlights as significant the manipulation of concrete materials by the participants as well as the mediator role of the teacher throughout the instructional process.
