Learning Chemistry

The process of teaching and learning chemistry is still considered difficult, for even with all the technology available for its improvement, this same issue is responsible for students’ distraction in class. The most common example are smartphones, which are devices that are increasingly versatile and have been inserted into the daily lives of almost all people. The use of mobile devices in the classroom can be a useful alternative for teachers to overcome the difficulties inherent in this process. This paper aims to present the contribution of educational android games in the process of learning organic functions at a public school in the city of Pau dos Ferros (RN). Initially, we use the Google Play Store® platform to check the availability of games dealing with organic chemistry topics. We choose four applications to be used as a supplementary methodology for solving exercises related to organic chemistry. Furthermore, we collected students’ opinions regarding the method used. We observed that these devices when used in a controlled, planned and an appropriate way can contribute to a positive approach to the motivation and interest of students during class.

Background Nasal osteotomy is a commonly performed procedure during rhinoplasty for both functional and cosmetic reasons. Teaching and learning this procedure proves difficult due to the reliance on nuanced tactile feedback. For surgical simulation, trainees are traditionally limited to cadaveric bones, which can be costly and difficult to obtain. Objective This study aimed to design and print a low-cost midface model for nasal osteotomy simulation. Methods A 3D reconstruction of the midface was modified using the free open-source design software Meshmixer (Autodesk Inc). The pyriform aperture was smoothed, and support rods were added to hold the fragments generated from the simulation in place. Several models with various infill densities were printed using a desktop 3D printer to determine which model best mimicked human facial bone. Results A midface simulation set was designed using a desktop 3D printer, polylactic acid filament, and easily accessible tools. A nasal osteotomy procedure was successfully simulated using the model. Conclusions 3D printing is a low-cost, accessible technology that can be used to create simulation models. With growing restrictions on trainee duty hours, the simulation set can be used by programs to augment surgical training.

Context: 3D printing can be used for a wide range of tasks such as the design and testing of prototypes and finished products in a shorter time. In mechanical engineering, prototype designs are continuously generated in academic class activities and final coursework projects by students and teachers. However, students show limitations while understanding the abstract concepts represented with such designs.Method: Firstly, a large scale 3D printer with improved technical specifications compared to traditional market options and similar price, was fabricated. By means of free software and hardware tools and easy-to-obtain alternative manufacturing materials, it was possible to decrease its manufacturing and operating costs. Then a set of study cases utilising the 3D printer in three different subject classes were designed and tested with two cohorts of students of Mechanical Engineering programme.Results: It was feasible to fabricate a cost-effective and practical 3D printer for constructing prototypes and pieces that benefit teaching and learning concepts in engineering and design areas. The experiments carried out in three subjects of engineering courses with second-year students, showed a similar trend of improving the average course grades, as it was observed in two cohorts in different terms.Conclusions: This type of low cost 3D printer obtained academic advantages as a didactic tool for the learning process in engineering and design subjects. Future work will consider applying this tool to other courses and subjects to further evaluate its convenience and effectivity.
