Desenvolvimento de um objeto de aprendizagem em forma de aplicativo para o ensino de estatística descritiva

Abstract

With the strong growth of informatics and the transformations of teaching models, software is emerging to support learning in a virtual way. This project consists in the development of an application (APP) to be used in schools as a motivation in the teaching-learning process of Descriptive Statistics through the exploitation of technologies that present particular and dynamic content, facilitating student learning through mobile devices, being that it is common sense that it is no easy task to thoroughly understand the mathematics discipline in High School. The content of the statistical APP developed for Android were: Central Trend Measures, Dispersion / Variation, Frequency Distributions and Graph Interpretation. The specific purposes of the present study are: to identify and enunciate possible learning objects (OAs) as Descriptive Statistics APPs, as well as to understand the application programming interfaces (APIs) based on events of Android, in addition to using the contents of Descriptive Statistics as thematic for the structuring of issues in the APP, as well as to structure functional, non-functional requirements and System Analysis diagrams as the software design phase. These purposes are necessary for the development of the APP, preparing students for the use of new technologies. In this line of reasoning, the literature shows that developing didactic activities in a Virtual Learning Environment (AVA) horizontalizes relations between the student-teacher audience, even in the solution of mathematical problems. Thus, ICTs are objects of this research to use virtual tools that, in the end, solve descriptive statistics problems in a dynamic way, promoting, in a certain way, student’s autonomy. In the development of the application we used bibliographical researches such as the contextualization of the content of Statistics, the current context of education technologies in teacher training, as well as learning objects and their use as applications. Some software are used in the development of this work, such as Android Studio software for APP programming using the Java programming language, Astah software to design APP according to Software Engineering, as well as descriptive statistics content and exercises. Methodologically, the literature was used for the development of the APP, from the survey of requirements until the implementation of APP in Android Studio as OA. As a result of the research, the software developed here is called StatisticAPP, in addition to compiling results of contents, exercises, correction and report, will motivate the student in the training through its playful interface through teaching-learning Statistics. In fact, it is concluded that even with the ephemeral institutional willingness to pass through the AVA class technologies in a skilled way, this does not prevent the teaching public from motivating itself to deepen the virtual contents to support its classes, since the public student already uses the virtual environment in extracurricular and leisure activities, thus providing a unique and more attractive formation. The development of the StatisticAPP was carried out and we verified that the diversity of the thinking is horizontal, particularly in the mathematical formation technological.
