CATÁLOGO MINERAL: OBJETO DE APRENDIZAGEM PARA APOIAR O ENSINO DE MINERALOGIA

Abstract

This study had as main objective to design and develop a Learning Object (LO) to support the teaching of mineralogy in courses related to Professional and Technological Education and to evaluate its effectiveness and quality. The creation of LO, called “Mineral Catalog” (CATMIN), was based on Ausubel's Theory of Meaningful Learning and the use of Concept Maps. The entire development process followed the steps of the INTERA Methodology, namely: contextualization, requirements, architecture, development, environments and standards, tests and quality, evaluation and availability. CATMIN was created between May and August 2019. The LO consists of a website created on the Wix platform, articulated with two electronic forms and a GDRIVE folder. The electronic form called “Mineral Catalog” is considered as the main component of CATMIN, where the user can create identification cards and conceptual maps from filling in information about the physical and chemical characteristics of mineral samples. The LO evaluation process was carried out with a group of 34 students from the technical course in mining at the IF Goiano - Campus Catalão, during the months of September and October 2019. The methodology used for CATMIN evaluation is characterized as applied descriptive, qualitative, in the case study format. The validation process was divided into seven stages and the evaluation of effectiveness was based on the measurement of the subjects' learning gain, through evaluative tests applied before and after the use of CATMIN. For the assessment of quality, an electronic form called “Questionnaire on the Quality of Learning Object” (QQLO) was used, which assessed the subjects' satisfaction under three main aspects: assessment of the content presented, level of usability and potential as a teaching tool. After analyzing the results, through the process of comparing the obtained graphics and the trend of the average scores and correct answers of the research subjects, the effectiveness of CATMIN was inferred. As for the quality assessment, 87.22% of the students rated the content presented as satisfactory, 81.39% rated the level of usability as satisfactory and 88.82% rated LO's potential as satisfactory as a teaching tool, which shows the proficiency and efficiency of CATMIN. Thus, the results suggest that CATMIN can be considered as an assertive tool to support the teaching of mineralogy, contributing to the improvement of educational performance and the generation of meaningful learning.
