(2019) Cabral, Jefferson de Carvalho; Nóbrega, Obionor de Oliveira; Lins, Fernando Antonio Aires; http://lattes.cnpq.br/2475965771605110; http://lattes.cnpq.br/8576087238071129; http://lattes.cnpq.br/1111059195459577
Currently, the Internet of Things paradigm is being seen as the protagonist of the technological revolution in which the computer age lives. In this paradigm, the objects present in our daily lives will be connected to us and other objects. One of the major concerns in the (IoT - Internet of Things) universe is energy efficiency. Assuming that all objects can be connected to numerous networks simultaneously transmitting and receiving data, the wireless technologies must be able to act efficiently in the traffic of the information between the nodes without compromising the life of the batteries of those devices. In the educational context, these technologies aim at the developmentof intelligent classrooms as well as the creation of static applications that have thefunction of automating some manual activities carried out by teachers and students.One of these static applications is known as Smart Attendance, which aims to automate and solve the problem of the loss of 10% of class time for taking attendance by using technologies that promise a low power consumption. Although some solutions automate class attendance, the waste of 10% of class time still persists. This has commonly occurred due to some factors such as lack of visibility of the problem and inadequate use of the technology. Considering the last factor, this work aims to evaluate the energyconsumption of smartphones by taking roll in Smart Attendance systems using Bluetoothand Bluetooh Low Energy (BLE) technologies. Through the literature review, it was possible to analyze the work in the educational environment and to understand theIoT’s performance in this context, to understand the operation of the BLE protocol andto compare it with Bluetooth, to explore the work related to the automation of class attendance and to define a specification of the system data traffic, its message flowsand its operation. In order to evaluate the system, it was considered the simulation technique, which was chosen based on the main criteria used to select the systems performance evaluation techniques. Then, we used the OMNet ++ simulator with theINET framework to create a Mobile Ad Hoc Network (MANET) configured with Bluetooth and BLE characteristics, where the nodes of this network were the student and teacher smartphones. The results of this research point out that there are no quantitative differences between the Bluetooth and BLE technologies when compared within the metrics package error rate and signal-to-noise ratio. However, it proves the efficiency of the BLE over Bluetooth considering the energy consumption metric which makesBLE the most rational choice, among those evaluated, for the implementation of a Smart Attendance.
Colagem digital no ensino de Arte: uma técnica de prática pedagógica mediada pelo uso do smartphone
(2023-06-06) Oliveira, Graziele Silva de; Lima, Felipe de Brito; http://lattes.cnpq.br/0144075272556954; http://lattes.cnpq.br/5568886130459536
Technological evolution has been increasingly relevant in education, providing new possibilities for teaching and learning. In this way, digital collage emerges as a pedagogical practice in order to explore creativity and expression of ideas. The general objective of the research is to analyze the use of the smartphone as a technological resource that mediates the digital collage technique in art teaching, based on this assumption, the specific objectives will discuss the use of the smartphone as an educational instrument in Basic Education, reflect the evolution of manual to digital collage as an artistic manifestation and to identify the teachers' perception about these perspectives. The theoretical framework included discussions about the use of smartphones as teaching equipment, the possibilities and potential of this device in teaching practice and the digital collage technique as a pedagogical practice. This is an exploratory/descriptive research with a qualitative approach, in which the methodological procedures adopted consisted of interviewing 4 Arts teachers in Basic Education, who work in public and private schools. were recorded and transcribed. The data obtained indicated that the smartphone as a technological tool can minimize the lack of a computer lab, adapting it to be a Maker laboratory in the classroom and the digital collage technique can stimulate skills and competences in students, developing future affinities in professional areas. Based on the results and discussions presented, it is considered that the smartphone, being this mediator in the applicability of the digital collage technique, has great significant potential, providing innovative and inclusive learning.
Explorando o potencial do audiovisual no smartphone como recurso pedagógico
(2023-10-19) Santos, Fábio Dênis dos; Silva, Leilane Jordão Pessoa da; Nogueira, Amanda Mansur Custódio; http://lattes.cnpq.br/0341879306272619; http://lattes.cnpq.br/0450985498841766; http://lattes.cnpq.br/6106009687389793
The present academic work aims to analyze the potential of using smartphones and audiovisual resources as pedagogical tools in the classroom, considering their advantages, challenges, and impacts on student learning. Contemporary education has been undergoing transformations due to technological advancements, with smartphones being a prominent technology. The research adopts a qualitative approach, employing interviews, content analysis, opinions, and the perspectives of students, teachers, and school administrators on the subject.For the theoretical discussions mentioned, the theoretical framework will draw from Beland & Murphy (2016), Nunes & Costa (2019), Bhandari, and Richard (2016), among other authors. The use of smartphones as pedagogical resources presents positive aspects, such as quick access to online information and resources, as well as flexibility for learning in different locations and times. However, it also raises concerns about distractions and misuse. Audiovisual resources, on the other hand, have been explored for decades as enriching tools in the classroom. The combination of smartphones and audiovisual resources offers opportunities to diversify teaching strategies and engage students more meaningfully.Collaboration among all stakeholders, including administrators, teachers, and students, is essential to ensure a balanced and efficient educational environment where technologies are used responsibly and productively.
Fotografia como recorte da paisagem: o uso de dispositivos móveis para estudos de desenho de observação
(2023-09-18) Lucena, Eduardo Gomes de; Bracchi, Daniela Nery; http://lattes.cnpq.br/6149456459123478; http://lattes.cnpq.br/2435416144293028
This research aims to analyze the integration of mobile devices in contemporary artistic practice, investigating the use of photographs captured by smartphones in observational drawing studies. Inspired by both the transdisciplinary approach of Renaissance artists and modern technologies, this study follows students from the Technical Course in Visual Arts at the Instituto Federal de Pernambuco – Campus Olinda. Similar to how Leonardo da Vinci used the camera obscura to depict singlepoint perspective and vanishing points, the cameras of mobile devices can serve as technical aids to crop the desired landscape, in addition to recording space-time and enabling the artist to explore intricate scene details. Within the context of this case study, two Painting classes were observed during three field trips. Through paintings created in a square near the campus, the frequent use of mobile devices as tools enriching the creative process became evident. These tools provide attributes that complement human vision, including zoom, cropping, and the ability to capture specific moments. By observing this practice, the research highlights the intersection of art and technology throughout history. The adopted methodology is grounded in a qualitative approach of Participant Observation, enabling the author to experience and record students' interaction with mobile devices during artistic practice. The motivation for this analysis stems from the author's role as a technician in the Painting and Photography labs at the Instituto Federal de Pernambuco, Campus Olinda.
