The present study concerns the validation of a questionnaire applied to first and last year undergraduate students in Biology, Sciences, Physics, Chemistry and Pedagogy, being selected two different institutions for each course. The research instrument went through the semantic validation, carried out by six PhD researchers in the areas of Teaching (Biology, Physics and Chemistry) and also through a pilot test with Biology students. After the semantic analysis and the pilot test, three questions were deleted so that the final questionnaire became composed of 81 questions. To evaluate the reliability of the instrument (statistical validation) the Cronbach Alpha test, factorial analysis, Kaiser-Meyer-Olklin (KMO) and Bartlett’s Sphericity were carried out. After the application of these tests, 30 assertions were eliminated, making the Principal Component Analysis (PCA) possible. The sample number was considered satisfactory for the systematization and analysis of the data, when the KMO value was analyzed.
