Exploring the long-term associations between adolescents’ music training and academic achievement

There is a positive relationship between learning music and academic achievement, although doubts remain regarding the mechanisms underlying this association. This research analyses the academic performance of music and non-music students from seventh to ninth grade. The study controls for socioeconomic status, intelligence, motivation and prior academic achievement. Data were collected from 110 adolescents at two time points, once when the students were between 11 and 14 years old in the seventh grade, and again 3 years later. Our results show that music students perform better academically than non-music students in the seventh grade (Cohen’s d = 0.88) and in the ninth grade (Cohen’s d = 1.05). This difference is particularly evident in their scores in Portuguese language and natural science; the difference is somewhat weaker in history and geography scores, and is least pronounced in mathematics and English scores (η2 p from .09 to .21). A longitudinal analysis also revealed better academic performance by music students after controlling for prior academic achievement (η2 p = .07). Furthermore, controlling for intelligence, socioeconomic status and motivation did not eliminate the positive association between music learning from the seventh to the ninth grade and students’ academic achievement (η2 p = .06). During the period, music students maintained better and more consistent academic standing. We conclude that, after controlling for intelligence, socioeconomic status and motivation, music training is positively associated with academic achievement.

Physical Activity, Obesity Status, and Blood Pressure in Preschool Children

Objective To examine the combined effects of physical activity and weight status on blood pressure (BP) in preschool-aged children. Study design The sample included 733 preschool-aged children (49% female). Physical activity was objectively assessed on 7 consecutive days by accelerometry. Children were categorized as sufficiently active if they met the recommendation of at least 60 minutes daily of moderate-to-vigorous physical activity (MVPA). Body mass index was used to categorize children as nonoverweight or overweight/obese, according to the International Obesity Task Force benchmarks. BP was measured using an automated BP monitor and categorized as elevated or normal using BP percentile-based cut-points for age, sex, and height. Results The prevalence of elevated systolic BP (SBP) and diastolic BP was 7.7% and 3.0%, respectively. The prevalence of overweight/obese was 32%, and about 15% of children did not accomplish the recommended 60 minutes of daily MVPA. After controlling for age and sex, overweight/obese children who did not meet the daily MVPA recommendation were 3 times more likely (OR 3.8; CI 1.6-8.6) to have elevated SBP than nonoverweight children who met the daily MVPA recommendation. Conclusions Overweight or obese preschool-aged children with insufficient levels of MVPA are at significantly greater risk for elevated SBP than their non overweight and sufficiently active counterparts.

Step based physical activity guidelines for preschool-aged children

Objective Public health organizations recommend that preschool-aged children accumulate at least 3 h of physical activity (PA) daily. Objective monitoring using pedometers offers an opportunity to measure preschooler's PA and assess compliance with this recommendation. The purpose of this study was to derive step-based recommendations consistent with the 3 h PA recommendation for preschool-aged children. Method The study sample comprised 916 preschool-aged children, aged 3 to 6 years (mean age = 5.0 ± 0.8 years). Children were recruited from kindergartens located in Portugal, between 2009 and 2013. Children wore an ActiGraph GT1M accelerometer that measured PA intensity and steps per day simultaneously over a 7-day monitoring period. Receiver operating characteristic (ROC) curve analysis was used to identify the daily step count threshold associated with meeting the daily 3 hour PA recommendation. Results A significant correlation was observed between minutes of total PA and steps per day (r = 0.76, p < 0.001). The optimal step count for ≥ 3 h of total PA was 9099 steps per day (sensitivity (90%) and specificity (66%)) with area under the ROC curve = 0.86 (95% CI: 0.84 to 0.88). Conclusion Preschool-aged children who accumulate less than 9000 steps per day may be considered Insufficiently Active.

The importance of physical education classes in pre-school children

The purpose of this study was to analyse differences between total physical activity (TPA) and moderate-to-vigorous PA (MVPA) of pre-school children during daily school hours when they attended the physical education class (PED) and school days without PE class (NPED) and to assess the contribution of PE classes to TPA in school hours. The sample was composed of 193 pre-school healthy children (96 girls) aged from three to five years old and was conducted between February and December of 2008. Children wore accelerometers for at least four consecutive days during school hours. Data were analysed with specific software, age-specific counts-per-minute cut-off points and a 5 s epoch were used. Independent and general linear model repeated measures were used to assess differences between gender and differences between different days within each gender, respectively. Boys engaged more MVPA than girls (P < 0.05). During PED, pre-school children engaged significantly more in TPA and MVPA than during NPED (P < 0.05). PE class contributed, on average, 27.7% for the TPA and 32.8% of daily MVPA during PED in both gender. The results of this study suggest that structured PA such as a PE class increased the daily TPA and MVPA level of pre-school children.

Intervalos melódicos: diferentes estratégias de aprendizagem

O presente documento foi realizado no âmbito do Mestrado em Ensino de Música, ramo Formação Musical, na Escola Superior de Educação e Escola Superior de Música Artes e Espectáculos do Instituto Politécnico do Porto. O objectivo central deste documento visa, num primeiro capítulo, contextualizar o meio, a escola e a turma. No segundo capítulo deste documento constará a reflexão da Prática Pedagógica em Formação Musical, no Conservatório de Música de Paredes. No terceiro capítulo será apresentado o Projecto de Investigação em estudo – Intervalos melódicos: diferentes estratégias de aprendizagem. Esta investigação surge no sentido de tentar perceber quais as estratégias que surtem efeitos mais positivos para a aprendizagem de intervalos melódicos. As estratégias adoptadas foram três, são elas: aprendizagem por canções; aprendizagem por grau conjunto; aprendizagem por canções e grau conjunto. Foram seleccionados 18 indivíduos com idades compreendidas entre os 8 e os 12 anos de idade, de ambos os sexos. Todos eles têm em comum o facto de frequentarem o 1º grau de Formação Musical. A metodologia utilizada foi o estudo de caso, com abordagem quantitativa. Para testar as diferentes estratégias de aprendizagem foi realizado um teste após um período de oito semanas (8 aulas). Será feita uma revisão bibliográfica, onde serão abordadas algumas perspectivas de diferentes autores, para que possamos compreender melhor o tema desta investigação. As conclusões deste estudo revelam que a aprendizagem de intervalos melódicos utilizando a complementaridade das estratégias por canções e por grau conjunto são mais positivas, ainda que os resultados não sejam muito evidentes.

Motivação de crianças e jovens para a prática vocal

Este relatório foi escrito no âmbito do estágio de Prática Educativa do Mestrado em Ensino da Educação Musical no Ensino Básico da Escola Superior de Educação do Instituto Politécnico do Porto. No primeiro capítulo encontra-se a caracterização dos contextos onde decorreu a Prática Educativa – escolas, turmas e comunidades educativas. O segundo capítulo engloba a reflexão e fundamentação das opções realizadas ao longo das três Práticas Educativas, que resultaram da negociação entre os ideais, os programas e as crianças e os jovens envolvidos, suas competências, anseios e motivações. O terceiro capítulo é dedicado ao projeto de investigação realizado sobre a motivação de crianças e jovens dos 2º e 3º ciclos do ensino básico para participarem em atividades de prática vocal extracurriculares e suas implicações para a Educação Musical na sala de aula. O contraste entre a motivação dos alunos na sala de aula e em atividades extracurriculares suscitou o desenvolvimento deste estudo em dois contextos: o Coro dos Meninos Cantores do Município da Trofa e o Clube de Canto da Escola Básica Augusto Gil. A reflexão sobre a Prática Educativa é um instrumento ao serviço dos professores que lhes permite avaliar, e avaliarem-se, e introduzir mais consciência e reflexividade na sua acção, com vista a melhorá-la continuamente e a torná-la pertinente para o percurso dos seus alunos num mundo em constante mudança.
