As potencialidades da implementação de atividades práticas de caráter investigativo e interdisciplinar em ciências no 1.º Ciclo

O estudo analisa o contributo das atividades de investigação em ciências e da interdisciplinaridade na promoção das aprendizagens dos alunos. Trata-se de uma investigação na própria prática em contexto de estágio, realizado numa escola do 1.º Ciclo do Ensino Básico do Concelho de Santarém. Utilizaram-se como técnicas de recolha de dados a observação participante e a análise documental. Os resultados demonstraram inúmeras potencialidades da implementação de atividades práticas de caráter investigativo e interdisciplinar nas aprendizagens dos alunos. Para além disso, evidenciaram o desenvolvimento dos conhecimentos didáticos da futura professora e alterações na forma como conceptualiza os papéis em sala de aula.

The influence of an in-service programme on primary teachers conceptions about practical work

The purpose of this study was to investigate how an in-service programme influenced primary teachers’ conceptions about practical work. Ten elementary teachers participated in a Portuguese city in an one-year professional development programme, which aimed to promote the use of practical activities in classroom. Semi-structured interviews and classroom observations were both used to examine changes in teachers’ conceptions about science teaching and in their classroom pratices. Data also included written artefacts, such as teachers’ written reflections, lesson plans, activity sheets, assessment items and student work samples. Based on the analysis of the data, the changes in teachers’ conceptions were organized into four categories: student and learning, teacher and teaching, science teaching, and teaching context. Throughout their participation in the programme, teachers pointed out several constraints related to planning and implementing practical activities. Results indicate that most teachers were able to overcome their initial difficulties and progressively gained more confidence in using student-centered pratices. However, one year after the end of the programme, teachers reported that their actual practices did not changed significantly, particularly with regard to inquiry-based practical and collaborative activities, which remained absent or rare. Implications for professional development and further research are discussed.
