MODEL OF FACTORS AFFECTING THE INDIVIDUAL INTEREST OF STUDENTS IN BASIC SCIENCES: DESIGN AND VALIDATION OF A QUESTIONNAIRE

The purpose was to design and validate an instrument to measure a set of endogenous and exogenous factors that affect the individual interest of students in learning basic sciences. First, a multivariate factor model was developed and then the questionnaire was designed, which was submitted to content validation with the participation of judges and a pilot test. The construct validation was done through exploratory factor analysis, with a sample of 274 secondary school students, five latent dimensions were identified. The confirmatory factor analysis was carried out with a sample of 336 students. The results show optimal evidence of the questionnaire that corroborates its validity with 18 items. It is a practical instrument that allows empirical inquiries to be made about the effects of each of the factors that affect individual interest through perceptual evaluations of the students, giving rise to multivariate diagnoses.
