Geometry is a branch of Mathematics that helps us to work with distances, volumes, and areas in the real world. However, learning content related to Spatial Geometry, whose visual appeal should be an invitation to study, presents an unusual obstacle for the student: how to understand the elements of a three-dimensional object if they are normally presented in a two-dimensional way (e.g., drawn on the whiteboard or book)? There is several software that can be used in the teaching of Space Geometry. However, in most times, the teacher has no contact with these tools, either due to unavailability of hardware to interact; or due to difficulty in acquiring the software, which in turn may be due to the cost or lack of knowledge of the means to make the acquisition. The focus of this paper is to present the experience report on the use of Augmented Reality using tutorials developed by NIEP group, aiming to generate personalized material for use in the classroom by high school students in Mathematics, in the teaching/learning of Space Geometry. The results found demonstrate improved learning, better understanding of the content and reduced learning time.

Mobile devices have become quite popular over the past few years and as a result, the number of applications for the most diverse functions are available for download, many of them free of charge. However, this range of applications does not follow minimum usability parameters, which results in a high level of rejection by users. Within this mobile world, the insertion of devices that aid the health processes, called m-health, has shown an exponential growth in recent years and with this, the warning signal about the efficiency and security of information has been triggered. To remedy this weakness, the introduction of usability techniques during the application development process appears as crucial for minimizing the problem. Numerous studies cite the need for usability in m-health applications, but none of them points out how to obtain it. In this way, this work aims to verify if the design guidelines provided by the Google / Android platform, which is presented as a contribution to mobile software developers, presents guidelines that make it possible to obtain the maximum usability of these applications, considering the proposed user profile and the context of use involved. To this end, the proposal will be based on the comparison between the guidelines contained in the ISO standard (9241) and in consultation with the style guide of the platform called material design.

Educational Robotics refers to an application of technology in the pedagogical area that offers participants the opportunity to propose and solve difficult problems. So, what is learned by the child’s own effort has much more meaning for him and adapts better to they mental structures. Educational Robotics can be separated according to the apparatus used, which may be the use of commercial kits (e.g., LEGO EV3 or FISCHER TECHNIC) or low-cost kits (e.g., based on Arduino). Commercial kits typically have graphical programming interfaces tightly coupled to their components. Low-cost kits, on the other hand, do not have a defined interface and, therefore, depend on the search for software that allows their programming, but which have no obligation to work perfectly with all the components of the kit. This article shows an analysis of some Visual Programming Platforms (VPP) for educational robotics. This work also presents the design of a robotics VPP based on Arduino, designed for the inclusion of educational robotics to Brazilian children aged 8 to 14 years old.

Pregnancy is an important phase in women's lives, prenatal care is important to prevent diseases and ensure that women and babies can have a better quality of life. However, in Brazil, many pregnant women still do not perform due prenatal care, there are several factors that contribute to the failure to perform prenatal care among them: geographical factors. Pregnant women who live far from health units are unable to start pregnancy care in time. This work proposes a viable and low-cost alternative for the government or private sector companies. A Microservices architecture is presented, capable of meeting requests from pregnant women via mobile application and allowing health professionals to monitor the pregnancy evolution of a health unit. The architecture was designed to offer satisfactory performance, scalability and simplicity.

Pregnancy is an important stage in a woman's life, yet many women still do not get proper prenatal care. Failure to follow prenatal care can cause problems for the woman and the child. An important step in prenatal follow-up is the educational training for the woman, which allows her to overcome fears and get to know herself better. This work proposes a mobile application to support the woman who performs prenatal care in a public health unit and with this receive a better educational training on gestation. In addition, the application should allow a better mapping of pregnancy as well as concentrate data to better analyze the use of public funds and identify needs of public agencies acting based on identified demands.

Educational robotics is one of the ways that educational institutions use to expose that they have curriculum with technological approaches and innovation. Most of the studies that deal with the use of robotics in the classroom approach the student's point of view or even the associated didactics, but without exposing how or even what materials were used. In this work is exposed the report of experience of a teacher in the use of the LEGO EV3 kit, its difficulties in understanding the materials available, assembly and programming of the robot.
