Uso do Arduino para Ensino de Conceitos Intermediários de Programação

The use of Arduino to introduce basic programming concepts has been widely investigated by several studies in the literature. Despite of important contributions, we observed the lack of studies that evaluate such instrument to teach programming intermediate concepts, i.e., after the introductory programming topics. Therefore, this paper aims at comparing the influence of Arduino on students’ motivation when used to solve basic and intermediate practical programming exercises. An experimental study carried out with 62 students showed that students felt less competent when using Arduino to study programming intermediate concepts. Resumo. O uso do Arduino para introdução de conceitos iniciais de programação tem sido amplamente investigado por trabalhos na literatura. Apesar das importantes contribuições, observou-se a carência de estudos que avaliem esse instrumento para o ensino de conceitos intermediários, ou seja, posteriores aos tópicos introdutórios de programação. Logo, este artigo tem como objetivo comparar a influência do Arduino na motivação dos alunos quando utilizado na resolução de exercícios práticos básicos e intermediários de programação. Um estudo experimental realizado com 62 alunos mostrou que os alunos se sentiram menos competentes ao utilizar o Arduino para estudo de conceitos intermediários de programação.

A décima edição do WAIHCWS pretende promover a continuidade das discussões sobre as oportunidades e os desafios que a Web Social traz para a comunidade de pesquisa em Interação HumanoComputador (IHC) no Brasil e no mundo, colocando em evidência, especialmente neste ano, o tema “10 edições do WAIHCWS: retrospectiva, tendências e novos desafios”. O tema representa uma oportunidade para analisar o caminho percorrido por essa comunidade até aqui, bem como os avanços alcançados e os desafios que ainda precisam ser superados tendo em vista as novas tecnologias e formas de interação.

Um framework de classificação de complexidade para infográficos

Infographics have been used as learning materials due to their informative nature. Empirical evidence shows that this kind of visualization affects students’ learning and interest. However, providing further details on which parameters ensure positive results is still required. An example of such parameter is the complexity of the infographics. Therefore, there is a need to obtain information on the impact of infographics of different levels of complexity in learning. Observing the lack of guidelines to classify the complexity of infographics, we propose a framework that considers three dimensions (i.e., visual, verbal and conceptual) to score infographics and, generate a complexity measure. We carried out a controlled experiment to evaluate the framework and verify if our complexity measure reflects the real perception of the users. Our results showed that users learned more from infographics classified as low and medium complexity. We conclude that the complexity of an infographic is a factor that affects learning and should be considered by teachers and content creators when deciding to use infographics as learning materials.

Os resultados apontam que sistemas computacionais tem sido usados de forma satisfatoria no ensino de criancas autistas, mas poucas sao as tecnologias assistivas desenvolvidas com o amparo em diretrizes de acessibilidade, usabilidade e respaldadas por metodos de intervencao efetivos e que atuem como mediadores nos processos de ensino- aprendizagem e comunicacao alternativa de criancas autistas em ambiente escolar.

Hydrogels Based on Chitosan and Chitosan Derivatives for Biomedical Applications

Chitosan (CS) is a polymer obtained from chitin, being this, after the cellulose, the most abundant polysaccharide. The fact of (i) CS being obtained from renewable sources; (ii) CS to possess capability for doing interactions with different moieties being such capability dependent of pH; (iii) plenty of possibilities for chemical modification of CS; and (iv) tuning the final properties of CS derivatives makes this polymer very interesting in academic and technological points of view. In this way, hydrogels based on CS and on CS derivatives have been widely used for biomedical applications. Other important technological applications can be also cited, such as adsorbent of metals and dyes in wastewater from industrial effluents. In pharmaceutical field, hydrogels based on CS are often used as drugs’ and proteins’ carrier formulations due to the inherent characteristics such as the biocompatibility, nontoxicity, hydrophilicity, etc. This chapter is an attempt for updating and joining the plenty of available information regarding the preparation, characterization, and biomedical application of hydrogels based on chitosan and chitosan derivatives. More than 260 references are provided, being the majority of them published in the last 10 years.

Conventional and Unconventional Crystallization Mechanisms

Understanding the crystallization behavior of fats and oils is essential to ensure certain desirable characteristics in a given industrial application. In recent years, some advances in the structuring of lipid phases have enabled a direct influence on the food properties. The structuring mechanisms of lipid bases can be classified as either conventional or unconventional. Conventional crystallization mechanisms consist of nucleation, growth, and maturation of the crystals, thus resulting in a crystalline lattice. Co-crystallization or seeding agents and emerging technologies such as ultrasound can be used to aid in crystallization and improve the physical properties of fats and oils. Unconventional mechanisms bring organogel technology as a trend, which consists in the use of self-assembly agents to entrap the liquid oil, resulting in a structured gel network. In this chapter, the formation process of crystalline networks and gel networks will be presented in stages, highlighting the main differences related to the mechanisms of formation and stabilization of both types of networks.
