Telefone celular como recurso didático no ensino de física

Currently, there are several factors that suggest the need for the school to review their teaching practices: 1) the speed with which information and communication technologies - ICT are spread throughout society and in particular the increasing use of mobile phone by groups in school age;2) the scope and power of integrating ICT convergence of these technological resources, that can be used as teaching resources; 3) the fact that nowadays students grow up in a technological world and make their thought patterns operating in accordance with this reality, etc... In contrast, there are educators unrelated to the appropriation of ICT, presenting, in many cases, resistance to them. There is a incongruity between how individuals use mobile phones, for example, inside and outside the school. There are also educators, schools, public educational departments claiming to be against mobile phones usage; bills and laws regulating their use in educational space, etc... For these controversial aspects we have investigated whether cell phone use as a teaching resource practices mediator in Physics teaching. For this purpose, we developed an applied research with qualitative and exploratory approach about the objectives, adopting participant and the technical procedures. A documental and bibliographical research was taken. First of all, data were collected by e-mail, through a multiple choice questionnaire applied to private school teachers in southern Brazil, to identify the researched reality and develop teaching practices likely to be applied in the studied corpus. Then, such practices were applied in workshops located in Curitiba and Ponta Grossa cities, in Paraná state. During the application, data was collected by the researcher's field notes. Then, we recorded chats about the workshops from an instant message software (msn messenger), and we took photographic records. Data analysis was performed by triangulation. The results showed the need to enhance continuing education courses for teachers and the production of national academic literature, such as articles, dissertations, theses and books that explore the theme of the cell phone and its functionality in educational spaces as an educational resource mediator in the practices of teaching Physics. They are available in the dissertation defended in 2012, and now are also systematized in this book, organized as a final product of research conducted by the Graduate Program in Science Education and Technology UTFPR, Campus Ponta Grossa-PR.

Estatística com projetos: uma alternativa de ensino e aprendizagem

This work presents the use of projects as an alternative for teaching statistics, for that it was elaborated a Project that involves the educational socioeconomic reality from the families of the students and built a link between the reality and the scholastic knowledge. This project was applied in Sesi School - Pato Branco between the months of August to September 2014 with 25 students from the 1o and 2o grades from High School. To work the statistics concepts a questionnaire was applied for the parents of the students of the Project´s, they answer it and through these answers the students made frequency tables and graphs, besides measure calculations on measures of central tendency and dispersion measure. All of the construction were realized manually and in the Excel spreadsheet and some of them were chosen to be in this work to with the purpose of showing the hits and the mistakes done. The students worked in groups of 5 students, except in the last class when it was done a test referring to the contents taught in the classroom and a questionnaire for them to evaluate the project´s application. The results show that the teaching of Statistics trough projects motivate the students interest, stimulating the statistical reasoning, in addition made the students know a Math that was different from the one they have already known, with a lot of calculation but with no final objective.

A narrativa histórica de Alexandre Wollner sobre o design brasileiro em sua relação com arte, indústria e tecnologia

This work aims to investigate the historical narratives in which the graphic designer Alexandre Wollner assembled about the development of its own profession in Brazil, focusing the ways in which his discourse points relations among design (with greater emphasis in graphic design) and visual arts, the industrial development and notions about technology. Firstly, the theoretical setup searched for dialogues with design historians, with Mikhail Bakhtin, specially his concepts about “ideology” and “discourse’, and the theory of Field Autonomy by Pierre Bourdieu applied in the artistic practice. Following, the relation between Wollner’s own journey and the Brazilian industrial development is shown, and, at last, three of his historical texts are studied, which are written in different moments (1964; 1983; 1998), being those in which the analyzed author wished to point out the origens, events and names that are more remarkable. Throughout the work, it is pointed the importance of Wollner’s contact with the modernist european ideologies that share an abstract and rationalist matrix found at Hochschule für Gestaltung Ulm (HfG Ulm), the german design school from the city of Ulm, in the 1950s. Such modernist discourse understood the practice of design as a method with scientific character, being then different of some other more recurring artistic professional practices in some productive sectors. Wollner aimed to apply such ideals in his professional practice, being the foundation of the paulista office forminform, in 1958, one of his first expressions of such posture, and in his academic practice, helping the foundation of the Escola Superior de Desenho Industrial (ESDI), in Rio de Janeiro, in 1963. Such modernist ideals went along with moments of the Brazilian industrial development during the government of Juscelino Kubitschek (1956–1961) and the “Economical Miracle” from the military government (1968–1973). Wollner argued about the need for the development of national design as a technological and productive differential that would help the growth of national industry, based on Ulm’s project model concept. It is defended that Wollner’s professional and intelectual path, in his efforts of thinking a history of Brazilian design through the choice of pioneers in the area, was founded on an “ideal model” of design, leaving aside the modernist experiences from the 1950s. Such posture would indicate a search for validation of his own profession that was beginning to become more evident in Brazilian productive means, aiming the creation of a differential space in comparison with pre-established practices, usually link to graphic artists from the time.
