The study and interest of figurate numbers can be observed even in ancient Greece. On the other hand, it becomes very important the historical understanding about an evolutionary process and the particular generalization of such 2D, 3D and m-D figurate numbers and they remain the interest of current scientific investigations. On the other hand, in…

The teaching of Mathematics in the context of the Mathematical Olympiads in Brazil constitutes a context of research still little considered, with particular interest in the teaching and the learning phenomena. In Brazil, we identified a large number of teachers and students who do not participate in official math competitions, such as the…

In Brazil we have identified a predilection of the authors of Mathematical History books for the discussion of the fundamentals of Differential and Integral Calculus. On the other hand, when we consider the teaching of Mathematics in the school context, it is essential to know the teaching of the historical and dynamic evolution of the concepts,…

This article presents a social and collaborative model for content enrichment in Ubiquitous Learning Environments. Designed as a loosely coupled software architecture, the proposed model was implemented and integrated into the Classroom eXperience, a multimedia capture platform for educational environments. After automatically recording a lecture…

This study investigated the use of digital learning objects in elementary and secondary schools. The specific objectives were: a) to identify the frequency with which learning object are used by teachers, the type of object most frequently used, the teaching strategies that is more frequently adopted, the main reason for the use of learning…

Within the field of electric power systems, the study of electrical equipment can be frustrating and demotivating because of the lack of a clear vision of how this equipment functions and operates in a real environment. The use of virtual reality can provide a more concrete representation for students, who rarely have the opportunity to visit a…

Purpose: The purpose of this paper is to present the development of a software for stereo visualization of geometric solids, applied to the teaching/learning of Descriptive Geometry. Design/methodology/approach: The paper presents the traditional method commonly used in computer graphic stereoscopic vision (implemented in C language) and the…

Information and Communication Technologies (ICT) in education provide a new learning environment where the student builds his own knowledge, allowing his visualization and experimentation. This study evaluated the Geogebra software in the learning process of Calculus. It was observed that the proposed activities helped in the graphical…

The WISE Report from the Clayton Christensen Institute explores perspectives on the blended learning process through the institute's comprehensive surveys of the three countries. This report touches on a number of school-based efforts to implement educational technology, focusing on whether, and how, a sample of brick-and-mortar schools in Brazil,…

Open Educational Resources have emerged as important elements of education in the contemporary society, promoting life-long and personalized learning that transcends social, economic and geographical barriers. To achieve the potential of OERs and bring impact on education, it is necessary to increase their development and supply. However, one of…

The use of computers in the teaching and learning process is investigated by many researches and, nowadays, due the available diversity of computing devices, tablets are become popular in classroom too. So what are the advantages and disadvantages to use tablets in classroom? How can we shape the teaching and learning activities to get the best of…

The "2015 NMC Technology Outlook for Brazilian Universities" is a collaborative research effort between the New Media Consortium and Saraiva to inform Brazilian higher education leaders and decision-makers about important developments in technologies supporting teaching, learning, and creative inquiry in higher education across the…

The technological resources used for pedagogical innovation in the form of distance education have increasingly been incorporated into face-to-face education. This article describes the experience of the Federal University of Lavras--Brazil--with new ways to apply technology in face-to-face undergraduate courses. This paper presents (i) the…

The "2014 NMC Technology Outlook for Brazilian Universities: A Horizon Project Regional Report" reflects a collaborative research effort between the New Media Consortium (NMC) and Saraiva to help inform education leaders in Brazil about significant developments in technologies supporting teaching, learning, and creative inquiry in higher…

Purpose: The purpose of this paper is to propose a web-based tool that enables the development and provision of learning designs and its reuse and re-contextualization as generative learning objects, aimed at developing educational materials. Design/methodology/approach: The use of learning objects can facilitate the process of production and…
