Sequência de ensino investigativo através da construção de um túnel de vento de baixo custo
Abstract
This dissertation aims to develop an research-based teaching investigation teaching sequence (RTS) through the use of low cost experimental activities to address concepts of flight theory in high school. The initial experimental activity was the construction of a prototype called “Radial Lift Simulator” and later a “wind tunnel” with accessible materials was built. The textual and pictorial production of students from the 1st year of high school in a state school in the urban area of the city of Santarém was analyzed. Descending hierarchical categorization (CHD) was used in addition to the similarity and word cloud analyzes in the answers to the questions proposed in the first and third experimental activity of this RTS, through the software IRAMUTEQ (Interface of R pour les Multidimensionnelles Analyzes de Textes et de Questionnaires). It was concluded that most of the reports after the application of RTS identified the different phases of the flight and explained the lift force via Bernoulli and Newton's Laws.
