Um aplicativo para o estudo de derivadas

Abstract

This research investigates the use that students who have already taken the discipline of Differential and Integral Calculus make of an application developed for the study of derivatives, from the question: what evaluation do these students do about this application? The proposed application is composed of two phases, the first has the aim to do a content review, while the second one prioritizes the study of graphical representations of the functions and their derivatives. The questions elaboration of the second phase was based on the Theory of Registration of Semiotic Representation and uses at least two registers of semiotic representation in each question. The application was tested by 10 volunteer students from the courses of Degree in Mathematics and Agroindustrial Production Engineering from different classes of a state university which met the prerequisites. From an online questionnaire, they made the evaluation of usability, efficiency and the application data. It has been realized that the cell phone can become a strong ally for both teaching and learning. Among the factors pointed out is the possibility of using the application for study, in offline mode, at any time and place, besides dynamicity. The "Derivative Quiz" application is part of this dissertation and its interface can be found in the educational product: "From paper to cellphone screen: an application for derivative studies". The questions used in the two phases and some suggestions to teachers are available in Educational Product II: "Notebook for questions of the study of derivatives" and are available for print and can be used in the classroom.
