- A (Auto)Aprendizagem de QDASPublication . Costa, António Pedro; Freitas, FábioAs primeiras preocupações sobre as competências computacionais (Brent,1984; Cuilenburg, J. J. van, Kleinnijenhuis, J., & Ridder, 1988) na utilização QDAS (Qualitative Data Analysis Software), surgem no século passado, nos anos 80, em paralelo com o surgimento das primeiras ferramentas. Desde então, e com mais ênfase nos últimos 10 anos, surgiu a necessidade de compreender a relação entre os estilos de aprendizagem dos utilizadores deste tipo de ferramentas e a tipologia de formação quando envolve o uso de software. Tal compreensão pode proporcionar grandes contribuições para as conexões e implementações de cursos de formação mais eficientes e eficazes (Inal & Güner, 2015; Freitas, 2020). Dito de outra forma, o Design Instrucional, que pode revelar-se eficaz para certos utilizadores, pode não ser a abordagem mais eficaz para outros que manifestem um estilo de aprendizagem diferente (Pashler, Mcdaniel, Rohrer, & Bjork, 2009; Freitas, 2020).
- Autoaprendizagem online do webQDA: uma análise de grupos focaisPublication . Freitas, Fábio; Souza, Francislê Neri de; Costa, António PedroO recurso aos Qualitative Data Analysis Software (QDAS) é algo cada vez mais incontornável entres investigadores qualitativos. Porém, o uso destas ferramentas digitais não é pacifico, pois, o processo de aprendizagem pode ser uma barreira para os investigadores. Este estudo é parte integrante de um projeto de investigação e procura analisar esta curva de aprendizagem através da recolha de dados relativos à análise do Protótipo de Aprendizagem online (PAo) do webQDA®. Este estudo de natureza qualitativa teve por base dois grupos focais. Os resultados demonstraram que, apesar do PAo ser uma ferramenta útil na aprendizagem, apresenta limitações em termos de Usabilidade, o que acaba por proporcionar uma má Experiência de Utilizador (UX). Esta análise foi realizada com o próprio webQDA® e mostrou-se essencial na identificação das fragilidades do PAo e para o processo de criação de diretrizes gerais de um Ambiente de Autoaprendizagem online para o webQDA®.
- Designing a mobile app to promote healthy behaviors and prevent obesity: analysis of adolescents’ preferencesPublication . Frontini, R.; Sousa, P.; Dixe, M. A.; Ferreira, R.; Figueiredo, M. C.To ensure that adolescents adhere to programmes promoting healthy behaviors, these programmes must be appealing and interesting. This study aims to characterize and assess the devices, operating system and type of mobile apps frequently used by adolescents; understand the features that mHealth apps should have to be appealing; comprehend the facilitators and barriers for adolescents to use mHealth apps. The sample comprised 165 adolescents (12–18 years) from the main population, recruited in 2018. Most participants used smartphones and the Android system. Food and physical activity suggestions were considered the most important features for an mHealth app. 62.6% had never tried an mHealth app. For those who had tried one, 26.0% stated it was to improve health status/lifestyle. Their favorite feature was physical exercise tips/plans (41.8%). Adolescents pointed out that the reasons that made them keep using the app were utility and interest (35.7%). Regarding possible barriers, 48.4% reported a lack of a senseof need/practical utility, and 18.8% considered notifications as their least favorite feature. Lack of interest was pointed out for 38.2% as the main reason for stopping use. Results provide practical information for the planning, design, and implementation of future mHealth apps for the promotion of healthy behaviors–an important implication for future research in this area.
- Golf-Putting Performance in Skilled Golfers at Different Distances to the HolePublication . Dias, Gonçalo; Couceiro, Micael; Mendes, Pedro; Gomes, Ricardo; Mendes, Rui; Vaz, Vasco; Martins, Fernando; Gama, José; Castro, Maria AntónioGolf putting occurs under highly variable conditions. Therefore, adapting to different putting distances is a challenge that the golfer faces and understanding the variables underlying performance in this task is important. The main objective of this study was to analyse the golf-putting performance in skilled golfers at different distances to the hole. Fourteen highly skilled golfers, adult male and right-handed (41.5 ± 13.2 years with an average handicap of 2.3 ± 1.7) performed the golf putting on a natural grass green, completing a total of 120 randomly ordered trials, 30 trials at each of the four different practice conditions (1, 2, 3, and 4 m away from the hole). A smart engineered putter (InPutter) was used as the data acquisition instrument to record several process variables at 100 Hz. Results indicated that golf-putting distances constrained movement organisation variables in specific ways. For example, as the distance to the hole changes, so do the informational constraints, shaping how a golfer needs to regulate performance. We concluded that the effects of different golf-putting distances required the implementation of functional solutions uniquely adjusted to each player. Furthermore, the perception that the player withdrew from the properties of the context (e.g., distance to the hole) was important to adapt the golf-putting process variables (e.g., amplitude and duration of the movement, among others). All these factors led to a decisive influence on how the golfer hit the ball and adjusted his performance. A major implication of developing a better understanding of the role of performance in golf putting is that coaches and players should allow functional movement behaviours to emerge during practice.
