Work planning began in 2015, at which time a review of the literature on the subject and on the methodologies that could be adopted in its development was carried out. As a result of the theoretical-methodological revision we decided to implement the project through a set of activities based on the methodology of Problem-Based Learning focusing on the theme "Movement" within the Physics curriculum of the 1st year of High School of a Technical School Of the State Center of Technological Education Paula Souza. The field study was developed from periodic meetings with a group of students who expressed an interest in the proposal. In order to direct the activities and ensure that the students developed the desired skills and abilities, we used the so-called Activity Schedules, which created situations to contextualize the learning situations. After conducting the research, we verified some evidence that the resources and methodologies adopted can help the teacher and contribute to the teaching and learning process, however, it is not the insertion of technology, by itself, the fundamental element that changes the conditions of Learning but rather to know how to take advantage of the characteristics that these resources have in order to make the student believe in the legitimacy of the school contents a...

Entendemos o Pensamento Computacional como um conjunto de processos de pensamentos que desenvolvemos para resolver um determinado problema de forma que busquemos reconhecer padrões, realizar decomposição do problema em partes menores, realizar um raciocínio algorítmico e abstrato, que podem nos ajudar a pensar em novas ideias à medida que conexões vão surgindo nesse desenvolvimento, ou seja, procedimentos organizados algoritmicamente que nos auxilie a pensar sobre o pensar.

Existem inúmeras técnicas de síntese de áudio utilizadas atualmente em instrumentos musicais profissionais, dentre as quais as mais fundamentais são a síntese aditiva e a síntese subtrativa. A síntese subtrativa se tornou popular e foi muito explorada entre as décadas de 60 e 70 com a criação de módulos analógicos de hardware que podiam ser interconectados, criando o conceito de sintetizador analógico modular. Apesar do uso deste tipo de sintetizador ter diminuído durante as décadas subsequentes, nos últimos anos sua utilização voltou a crescer e diversos modelos deste tipo de instrumento são vendidos atualmente, porém em geral a preços elevados. Sintetizadores digitais também disponibilizam a técnica de síntese subtrativa utilizando componentes eletrônicos customizados e desenvolvidos pelos fabricantes de sintetizadores com o intuito de utilizar avançadas técnicas de processamento de sinais, o que ainda mantém seus preços elevados. Neste trabalho investigamos a hipótese de que é possível desenvolver um instrumento musical funcional e de qualidade com recursos limitados de processamento, e exploramos essa hipótese implementando síntese subtrativa em uma plataforma acessível e de baixo custo. O desenvolvimento é baseado em linguagem orientada a objetos para criação de módulos de software replicando as características dos módulos encontrados em sintetizadores analógicos modulares. Com esta abordagem, obtemos um software modular que pode ser facilmente modificado baseado nas preferências do programador. A implementação foi testada na plataforma Arduino Due, que é uma plataforma de baixo custo e contém um processador 32-bits ARM 84 MHz. Foi possível adicionar osciladores com algoritmo anti-aliasing, filtros, geradores de envelope, módulo de efeito, uma interface MIDI e um teclado externo, obtendo assim um sintetizador subtrativo completo. Além disto, incluímos no desenvolvimento a implementação de um órgão baseado em síntese aditiva, com polifonia completa e inspirado na arquitetura de órgãos clássicos, mostrando a possibilidade de possuir dois importantes e poderosos métodos de síntese em uma plataforma acessível e de baixo custo. Com esta implementação aberta e pública, buscamos contribuir com o movimento maker e faça-você-mesmo, incentivando novos desenvolvimentos nesta área, em especial na computação e engenharia, aumentando o uso e acesso a instrumentos musicais eletrônicos e a criatividade musical. / Subtractive and additive synthesis are two powerful sound synthesis techniques that caused a revolution when the first electronic and electro mechanic music instruments started to appear some decades ago. Subtractive synthesis became very popular during the 60s and 70s after the creation of analog hardware modules that could be interconnected, creating the concept of the modular synthesizers. After the initial impact, for some years these instruments faced a slow-down in its usage, a tendency that was reverted on the past decade. Nevertheless, the prices of these instruments are often high. Digital synthesizers also offer the subtractive synthesis technique, by using customized electronic components designed and developed by the synthesizers vendors in order to use the most up-to-date technologies and signal processing techniques, which also leads to high prices. In this project, we investigate the hypothesis that it is possible to design and develop a good quality music instrument with low budget electronic components and limited processing capabilities, by implementing this on a low budget and easy to use platform. The development is based on object oriented design, creating software modules that replicates the functionalities of analog synthesizer hardware modules. With this approach, we have a modular software that can be easily changed based on programmers’ preferences. The implementation was tested on the Arduino Due board, which is a cheap, easy to use and widely available platform and powered by a 32-bits ARM 84Mhz processor. We were able to add oscillators with anti-aliasing algorithms, filters, envelope generators, delay effects, a MIDI interface and a keybed, making a complete synthesizer. In addition to this, we included an additive synthesis organ design with full polyphony based on classic organs design, demonstrating the possibility of having two powerful synthesis methods on a cheap and widely available platform. With this design, suitable for low cost platforms, we intend to contribute to the maker movement and encourage new implementations in this area, especially in the computing and engineering fields, increasing the usage and access to (electronic) musical instruments and musical creativity.

According to NHTSA Traffic Safety Facts [9], bicyclist deaths and injuries in 2013 are recorded as 732 and 48,000, respectively. In the State of Florida the safety of bicyclists is of particular concern as the bicycle fatality rates are nearly triple the national average. Further Florida ranks #1 on bicycle fatality rate in the nation for several years. To determine the cause of near-misses and crashes, a detailed study of bicyclist behavior and environmental conditions is needed. In a Florida Department of Transport (FDOT) funded project, USF CUTR has proposed naturalistic bicycle study based on ride data collected from 100 bicyclists for 3000 hrs. To this end, Bicycle Data Acquisition System (BDAS) is being researched and developed. The main objective of this thesis work is to design and implement low power video and audio subsystems of BDAS as specified by domain experts (USF CUTR researchers). This work also involves design of graphical user interface (Windows application) to visualize the data in a synchronized manner. Selection of appropriate hardware to capture and store data is critical as it should meet several criteria like low power consumption, low cost, and small form factor. Several Camera controllers were evaluated in terms of their performance and cost. The major challenges in this design are synchronization between collected data, storage of the video and sensor data, and design of low power embedded subsystems.

With the increasing ubiquity of networked “smart” devices that read and gather data on the physical world, the disembodied, cognitive realm of cyberspace has become “everted,” as such technologies migrate the communications networks and data collection of the Internet into the physical world. Popular open-source “maker” practices—most notably the practice of physical computing, which networks objects with digital environments using sensors and microcontrollers—increasingly push human-computer interaction (HCI) into the physical domain. Yet such practices, as political theorists and some philosophers of technology argue, bypass the very question of subjectivity, instead lauding the socioeconomic liberation of the individual afforded by open-source hardware practices. What is missing across these discourses is a technocultural framework for studying the material ways that everted technologies articulate subjects. I argue that examining the various, contradictory forms of interface that emerge from physical computing provides such a framework. To support this claim, I focus on several case studies, drawn from popular physical computing practices and communities, and analyze the particular ways that these devices articulate subjectivity. I conclude by linking my technocultural framework with various feminist theories of boundary transgression and hybridity, and end by suggesting that, in an everted landscape, the subject is politically constituted by a proximity to present time and space. / Graduate / 0585 / shaunmac@uvic.ca
