O uso de ferramentas Educométricas na caracterização do perfil dos discentes do ensino médio integrado da cidade de Paulistana referente ao ensino aprendizagem de Química.

Abstract

The Educometric tools used in the school environment by education professionals have become increasingly innovative, resulting in a challenge to be faced and mastered by teachers in the classroom. And when used appropriately, they contribute significantly to the teaching-learning of students undergoing educational and professional training. In this context, this research sought to analyze and characterize the profile of satisfaction and learning difficulties of students studying Chemistry in the 1st, 2nd and 3rd grade classes of integrated high school at IFPI - Campus Paulistana, CETI - Luciene Santana da Silva and CETI – Paulistana, through a questionnaire administered on Google Forms. The methodology included the application of the questionnaire in the classes under study, followed by a descriptive analysis of the answers provided by the students. The data was organized in a multidimensional way and transformed into a matrix arrangement using the Excel platform. Subsequently, Principal Component Analysis (PCAs) models were developed in the PLS_Toolbox 5.2 (Eigenvector Research, Inc.) interface for MATLAB. The PCA models were able to correlate the main reasons why interviewees failed, pointing out the Chemistry subject as the most difficult or the main subjects that cause the most difficulty. The hours of sleep slept by students, study hours and lack of control over access to the internet and television stood out as the main agents responsible for failures. Chemometric tools, when applied in the educational environment (Educometrics), have demonstrated that they are capable of mapping, correlating and predicting the profiles of interviewed students, thus making them a potential tool in the search for better teaching quality indices.
