Mobile learning no ensino de química: um olhar para a geometria e propriedades das moléculas

Abstract

Increasingly present at school, new technologies bring challenges for teaching and student’s learning. Combining possibilities allowed by mobile devices with teaching can be fundamental to improve students’ learning of this generation. In teaching Chemistry, the tridimensional visualization of molecules may be a barrier to the comprehension of many topics, due to the high degree abstraction required for students. Thus, this research aims to evaluate a teaching proposal of molecular geometry, using a chemistry App, based on mobile learning. Therefore, 45 students of the 1st grade of high school of a public school, located in João Pessoa – PB, participated in the research. Organized on Three Pedagogical Moments, four classes were taught about molecular geometry. The data were collected with previous and final questionnaires and analyzed through content analysis. Based on the results, it was noticed that 97% of students consider positive the experience of using their smartphones in chemistry classes, and 93.9% consider that its use facilitated the learnign. As for the App, 78.8% of students consider that it helped to understand better molecular geometry. Regarding the approach, it was found that 100% of the sutudents consider good or great. The analysis of the results showed the students’ interest and motivation in using smartphones in pedagogical activities. For those reasons, this study presents good perspectives for future researches with this subject.
