O presente relatório está integrado na Unidade Curricular de Prática de Ensino Supervisionada II do 2.º ano do Mestrado em Ensino do 1.º Ciclo do Ensino Básico e de Matemática e Ciências Naturais no 2.º Ciclo do Ensino Básico. O relatório integra a descrição de duas intervenções, uma no 1.º Ciclo do Ensino Básico e outra no 2.º Ciclo, contando também com a apresentação do estudo Conceções
alternativas sobre o sistema cardiovascular em alunos do 2.° ciclo: estratégias de desconstrução recorrendo ao pensamento crítico. Esta investigação tem como objetivos gerais: (i) identificar as Conceções alternativas dos alunos do 2.º CEB sobre o sistema cardiovascular humano; (ii) avaliar o papel de estratégias recorrendo ao pensamento crítico na desconstrução de Conceções alternativas; (iii) verificar se as Conceções alternativas foram desconstruídas de forma duradoura. Para dar resposta aos objetivos definidos, realizou-se um estudo de caso, com recurso a métodos quantitativos e qualitativos e com características de uma investigação-ação, contando com 17
participantes de uma turma de 2.º Ciclo do Ensino Básico. Como processos de recolha de dados, recorreu-se à administração de um inquérito por questionário aos discentes em três momentos distintos, antes de iniciar a lecionação do conteúdo, no final e cerca de dois meses após findada a abordagem ao sistema cardiovascular, como também à observação direta e participante em sala de aula com registo de notas de campo. Os resultados deste estudo permitiram identificar as principais Conceções alternativas dos discentes sobre o sistema cardiovascular humano e mostraram que a utilização de estratégias que recorrem a algumas capacidades de pensamento crítico apoiou a desconstrução de Conceções alternativas dos alunos. De acordo com os estilos e ritmos de aprendizagem individuais, os efeitos da intervenção foram mais duradouros em alguns alunos.
This report is part of the curricular unit "Supervised Teaching Practice II" from the second year of the master’s degree in teaching Primary Education (1st Cycle) and Mathematics and Science (2nd Cycle). The report includes the description of two teaching interventions—one in the 1st Cycle of Primary Education and another in the 2nd Cycle—as well as the presentation of the study Alternative conceptions about the cardiovascular system in the 2nd Cycle: deconstruction strategies through critical thinking. This research had the following general objectives: (i) to identify the students’ misconceptions regarding the human cardiovascular system; (ii) to assess the role of strategies based on critical thinking in the deconstruction of such conceptions; (iii) to determine whether the misconceptions were deconstructed in a lasting manner. To address these objectives, a case study was conducted using both quantitative and qualitative methods, incorporating characteristics of action research. The study involved 17 participants from a 2nd Cycle Primary Education class. Data collection included the administration of a questionnaire to the students at three different moments: prior to the teaching of the topic, immediately after its completion, and approximately two months later. Additionally, direct and participatory classroom observation was carried out, supported by field notes. The results of this study allowed for the identification of the main misconceptions held by students about the human cardiovascular system. They also indicated that the use of strategies involving certain critical thinking skills supported the deconstruction of these conceptions. According to students’ individual learning styles and rhythms, the effects of the intervention proved to be more lasting in some students.
