- Alunos jovens (7 a 12 anos de idade) podem aprender a importância e a evolução das plantas? : casos de estudo com a metodologia IBSEPublication . Tavares, Ana Cristina; Cabral, Ilídia; Alves, José MatiasInquiry-Based Science Education (IBSE) e um método de ensino centrado no aluno e na investigação de questões, entendida como a forca motriz para a aprendizagem. Para compreender os impactos desta metodologia em aprendizagens sobre a importância, diversidade e evolução das plantas, a aula “A alga que queria ser flor” foi aplicada a 160 alunos, do 3o, 5o e 6o ano do nível básico de escolaridade (7-12 anos), em contato direto com as plantas e recorrendo a diferentes valências educativas. A aprendizagem e as atitudes dos alunos foram avaliadas aplicando pré e pós-questionários. ‘Conhecer os cinco grupos de plantas e sua evolução’ foi novo conhecimento adquirido, conseguido por mais de 50% dos alunos (52,5%, 97,6% e 89,5% dos alunos do 3o, 5o e 6o, respetivamente). No aumento global do aprendizado, os alunos do 5o ano revelaram também a maior pontuação nas respostas corretas/parcialmente corretas (217,1), depois o 6o ano (170,3), e por ultimo o 3o ano (88,6). A maioria dos alunos (> 49-78%) apreciou esta experiência IBSE, principalmente porque ‘Aprenderam mais’. No geral, os alunos ‘Sentiram-se mais inspirados’ (49-78%) e mais de 81% ‘Dispostos a adotar novas atitudes sobre a natureza’. Apesar de uma expressão e consistência pouco significativas, com a metodologia IBSE novos conceitos e atitudes sobre as plantas foram aprendidas por alunos dos 7 aos 14 anos, independentemente da idade.

- Loss of control over eating, inhibitory control, and reward sensitivity in children and adolescents: a systematic reviewPublication . Ramalho, Sofia Marques; Conceição, Eva; Tavares, Ana Cristina; Freitas, Ana Luísa; Machado, Bárbara César; Gonçalves, SóniaOverview: In recent years, there has been increasing clinical and empirical interest in the concept of pediatric loss of control over eating, particularly about its link with the executive functions related to the concept of impulsivity, such as inhibitory control and reward sensitivity. However, there has yet to be a comprehensive literature synthesis about the associations between these variables. A comprehensive literature synthesis would help identify future research directions to advance the field in this area. Therefore, this systematic review aimed to synthesize evidence concerning the associations between loss of control over eating, inhibitory control, and reward sensitivity in children and adolescents. Methods: The systematic review was conducted according to the guidelines proposed by PRISMA in Web of Science, Scopus, PubMed, and PsycINFO. The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess the risk of bias. Results: Twelve studies met the selection criteria and were included in the final review. Overall, methodological heterogeneity, variability in assessment methods, and the age of participants make it difficult to draw general conclusions. Nevertheless, most studies with community samples of adolescents indicate that inhibitory control difficulties are linked to the concept of loss of control eating. The presence of obesity seems to be associated with inhibitory control difficulties, regardless of the presence of loss of control eating. Studies on reward sensitivity are scarcer. However, it has been suggested that higher reward sensitivity is related to loss of control eating behaviors in young people, particularly binge eating. Conclusions: The literature on the link between loss of control eating and trait-level facets of impulsivity (low inhibitory control and higher reward sensitivity) among young people remains limited, and more studies on children are needed. Findings from this review may make healthcare professionals more aware of the potential clinical importance of targeting the trait-level facets of impulsivity and help to inform existing and future weight-loss/maintenance interventions in childhood and adolescence.
