- Promoção das competências da matemática funcional em jovem com síndrome de WilliamsPublication . Oliveira, Olga; M. L. Martins, FernandoO estudo de natureza qualitativa, de cariz interpretativo e design de investigação-ação desenvolveu um conjunto de atividades que promovessem num jovem, com Síndrome de Williams, competências matemáticas funcionais nomeadamente nas transações monetárias. Estas transações, do âmbito da Matemática Funcional, tiveram como base um conjunto de metodologias e ocorreram inicialmente em ambiente de sala de aula. As aprendizagens revelaram-se profícuas na evolução da compreensão e aplicação de conceitos matemáticos, tais como o uso do dinheiro. Verificou-se a sua aplicação em situações reais e isso contribuiu para o desenvolvimento da autonomia do aluno.
- TPACK : uma proposta de integração da tecnologia na aula de matemáticaPublication . Silva, Ricardo; Raimundo, Isabel; Rato, Virgílio; M. L. Martins, FernandoOs dipositivos tecnológicos são uma presença constante no quotidiano dos Nativos Digitais, estando também disponíveis em contexto escolar. Esta realidade implica que a tecnologia não deve ser encarada como algo externo aos processos de ensino e de aprendizagem, mas sim integrada na sala de aula em articulação com o currículo. O modelo conceptual Technological Pedagogical Content Knowledge (TPACK) permite ao professor estruturar uma abordagem que inclua de forma equilibrada conhecimentos a nível dos conteúdos, a nível pedagógico e, também, a nível tecnológico, partindo sempre do contexto único do grupo de alunos a quem se destinam as propostas didáticas. Neste artigo apresenta-se uma proposta de integração da tecnologia, baseada no modelo conceptual TPACK, na prática de sala de aula com base numa experiência de ensino efetuada numa turma do 1.º ano do 1.º CEB, cujo foco incidiu na modelação matemática como ambiente de aprendizagem, recorrendo a manipulativos virtuais, para desenvolver a compreensão dos sentidos da adição e da subtração. A sequência didática criada possibilitou ao professor fazer um acompanhamento diferenciado dos alunos, permitindo também que estes tirassem partido do ambiente de aprendizagem estabelecido para autorregularem as suas aprendizagens.
- Physical self-description and sport participation, by gender, of university studentsPublication . Campos, Francisco; Marques, Mariana; Silva, Sofia; M. L. Martins, Fernando; Simões, Vera; Franco, SusanaUniversity students, who are regular sport participants, showed a superior and more positively physical selfdescription in body fat, general physical self-concept and self-esteem perception (Silva, Vicente, Amaro, & Campos, 2016). In another study with university students, in order to investigate what they think about their own physical appearance (Silva, Saenger, & Pereira, 2011), it was concluded that 63% of male and 67% of female students presents dissatisfaction, although for contradictory reasons (female students were dissatisfied due to overweight; male students were dissatisfied due to the thinness index). Considering this, based on the presented studies, the aim of this research is to characterize and compare sport participants by gender - students of the Cuenca Campus of the Universidad Castilla La Mancha (Spain) - according 4 (four) dimensions of their physical self-description: (1) body fat; (2) general physical self-concept; (3) self-esteem; (4) physical appearance. It was applied a reduced version of the Physical Self-Description Questionnaire (PSDQ), translated to Spanish (Tomás, 1998). The data were collected from 175 university students (22,00±3,41 years old), regular sport participants (at least once per week): 86 females (21,15±1,99 years old) and 89 males (22,82±4,18 years old). After the application of the ANOVA one-way test is possible to confirm, comparing the male with the female sport participants, that there are no statistical significant differences in the dimensions: body fat (F=0,001; p=0,973); self-esteem (F=0,186; p=0,667); physical appearance (F=0,748; p=0,388). In contrast, there are statistical significant differences in general physical selfconcept dimension (F=4,269; p=0,040), having the male participants a higher mean of answer values (M=4,643).
- Who is the prominent tactical position in rink-hockey? : a network approach based on centrality metricsPublication . Oliveira, Patrícia; Manuel Clemente, Filipe; M. L. Martins, FernandoThe aim of this study was to verify the prominence levels of rink-hockey players in different competitive levels. For that reason, it was analysed the variance of network centrality metrics between competitive levels and tactical positions. Fifty-four rink-hockey players from five different levels (U12, U14, U16, U18 and Elite) were analysed during three official matches. The results did not found statistical differences in centrality levels of players between competitive levels (p-value = 1.00; partial eta square = 0.001; very small effect size). Nevertheless, tactical position (p-value = 0.001; partial eta square = 0.534; moderate effect size) had significant main effects on the centrality metrics. In this study it was found that defender and forward are the positions that most receive balls from the teammates. In other hand, the forward is the position that most passes performed until the U16 and in older levels the defender assumes the centrality in passes performed.
- New technologies to the study the golf puttingPublication . Fernandes, Orlando; Dias, Gonçalo; Couceiro, Micael; Manuel Clemente, Filipe; M. L. Martins, Fernando; Luz, Miguel; Mendes, RuiThe technology evolution, especially in the last decade, allowed major advances in golf putting analysis. This scientific advance benefited from multidisciplinary interaction, such as: biomechanics, engineering, mathematics and motor control. Utilizing digital cameras along automatic tracking techniques, it is possible to obtain valuable and accurate information about the putting gesture and/or ball trajectory. This can provide relevant feedback to athletes and coaches. In this work, we present several golf putting studies conducted on laboratorial environment. We believe that this work may contribute to a deeper analysis of human motor behavior and performance, not limited to this motor skill, but that can be applied to other motor patterns.

- Who are the prominent players in the UEFA champions league? : an approach based on network analysisPublication . Manuel Clemente, Filipe; M. L. Martins, FernandoThis study aimed to analyze the centrality levels of elite football players. Tactical positions and tactical line-ups were considered factors to be used in analyzing the variance in the prominence of players, measured by social network measures. The best 16 teams from the UEFA Champions league were analyzed during the entire competition. A total of 109 matches were analyzed for this study. Significant statistical differences between positions were found in % indegree (p = 0.001; ES = 0.268, moderate effect), % outdegree (p = 0.001; ES = 0.301, moderate effect) and % betweenness (p = 0.001; ES = 0.114, minimum effect). No statistical differences between tactical line-ups in % outdegree (p = 1.000; ES = 0.001, no effect) or % indegree (p = 1.000; ES = 0.001, no effect) were found. Central midfielders had the greatest values of centrality, thus confirming their importance in the linkage process of the team. Position had great influence on the centrality levels of players.
- Team’s performance on FIFA U17 World Cup 2011 : study based on notational analysisPublication . Manuel Clemente, Filipe; Couceiro, Micael; M. L. Martins, Fernando; Mendes, RuiThe main objective of the notational analysis of the game includes optimizing feedback to the performer and coach to improve performance (Liebermann, Katz, Hughes, Bartlett, McClements & Franks, 2002). The main objective of this work was to analyze the profile of the teams that competed on FIFA U-17 World Cup at 2011, most exactly, trying understanding the offensive profile of the most successful teams. In this way we applied the test of correlation to verify if the goals for average are related to number of matches (i.e., more successful teams). There is statistical evidence to assert that the pairs (wins and goals) are positively moderating related (p = 0.001). In fact it appears that there is a directly intimacy between pairs (since the linear correlation coefficient r (24) = 0.774), i.e., how much more goals for average, more wins happens. Through the analysis of dependent variables is possible to say that teams who wins more games, have a superior mean of goals per match but, in the case of goals against, the teams that achieve the higher level in competition have higher mean of the goals against. However are the teams that play more matches that show higher level of goals for average.
- Network analysis in basketball : inspecting the prominent players using centrality metricsPublication . Manuel Clemente, Filipe; M. L. Martins, Fernando; Kalamaras, Dimitris; Mendes, RuiThe aim of this study was to analyse the team-members cooperation in basketball by using centrality metrics of network. Different ages were compared in this study. Forty players (10 players of under-14; 10 players of under16; 10 players of under-18 and 10 players in amateurs with more than 20 years) voluntarily participated in this study. A total of 326 units of attack were generated based on the team-members interactions and then converted in final graphs. The one-way ANOVA for the factor tactical position found statistical differences in the dependent variables of %DCentrality (F(4,15) = 13.622; p-value = 0.001; n2 = 0.784; Large Effect Size) and %DPrestige (F(4,15) = 20.590; p-value = 0.001; n2 = 0.846; Large Effect Size). In conclusion this study showed that point guard was the prominent position during the attacking organization and that social network analysis it is a useful approach to identify the patterns of interactions in the game of basketball.
- Weekly physical activity patterns of university students : are athletes more active than non‑athletes?Publication . Manuel Clemente, Filipe; Nikolaidis, Pantelis Theodoros; M. L. Martins, Fernando; Mendes, RuiThe aim of the present study was to compare weekly physical activity (PA) and obesity-related markers in athlete and non-athlete university students. One hundred and twenty-six university students (53 males, 20.46 ± 2.04 years old, and 73 females, 19.69 ± 1.32 years old) participated in this study. Participants were fitted with a tri-axial accelerometer (ActiGraph wGT3X-BT, Shalimar, FL, USA) to assess the daily PA. Anthropometric measures of height, weight, BMI and %fat mass were determined with a stadiometer and an electronic scale. The comparison indicated that male and female athletes had a significant lower percentage of body fat than did non-athletes (p value = 0.001; ES = 0.043). Athletes spent significantly more time in light PA than did non-athletes (p value = 0.003; ES = 0.024). Female athletes spent significantly less time in sedentary mode than did non-athletes (p value = 0.040; ES = 0.008). On the other hand, female athletes spent significantly more time in light PA (p value = 0.003; ES = 0.017) and vigorous PA (p value = 0.001; ES = 0.086) than did non-athletes. Despite some statistical differences with minimal effect size, the results of this study suggested proximity between PA levels of athletes and non-athletes, mainly in the case of sedentary behaviour. No significant effects were found in the variances of PA tested in this study.
