Resumo(s)
Este estudo analisa o modo como os alunos percepcionam aulas de Química
planeadas segundo as Orientações Curriculares e orientadas para a investigação.
Especificamente, procura dar resposta aos seguintes aspectos: (i) potencialidades
atribuídas às actividades de investigação, (ii) mudança de perspectiva relativamente ao
ensino da Química, após o envolvimento em actividades de investigação, (iii) mudança
de motivação e auto eficácia em aulas de Química. O enquadramento teórico centrou-se
sobre finalidades e perspectivas de ensino, trabalho laboratorial, aprendizagem de
ciência, motivação e auto eficácia. A metodologia tem um carácter qualitativo e
descritivo. Envolveu duas turmas do 8º ano da escolaridade, numa escola da margem
sul do Tejo e uma proposta didáctica, centrada em actividades de investigação, para
leccionar Reacções Químicas.
Utilizou-se como técnica de recolha de dados (i) a gravação áudio das conversas entre
os alunos quando, em grupo, realizavam as actividades de investigação, (ii) os
documentos escritos produzidos pelos alunos após a realização das actividades de
investigação, (iii) três inventários por questionário, e (iv) a observação naturalista.
Numa primeira fase procedeu-se à transcrição das aulas gravadas. Depois realizou-se
análise de conteúdo sobre os documentos escritos por eles produzidos e sobre as
transcrições da áudio gravação. Numa terceira fase realizou-se a análise estatística dos
inventários por questionário.
Os resultados obtidos indicam que as actividades de investigação usadas como
estratégia de ensino nas aulas de Química, apresentam potencialidades importantes ao
nível (i) da mobilização de competências; (ii) do envolvimento dos alunos; (iii)
mudança da motivação intrínseca e extrínseca e da auto eficácia e (iv) aquisição de
conhecimentos. Os resultados deste estudo apelam a um repensar da problemática da
formação de professores, quer na formação inicial, quer na formação contínua de modo
a proporcionar situações de aprendizagem mais em sintonia com um ensino para o
desenvolvimento de competências e para o uso de actividades de investigação. Este
estudo revestiu-se de grande importância para a professora na medida que contribuiu
para o seu desenvolvimento profissional e para o reconhecimento da necessidade de
uma reflexão sistemática sob a sua própria prática e da inclusão da componente
investigativa na prática
The purpose of this study is to analyse the way students view research-based Chemistry lessons planned according to the curricular guidelines. It tries to address the following issues: (i) the importance of research activities, (ii) a new perspective on Chemistry teaching process after experimenting research-based teaching strategies, (iii) different motivation and self-efficiency in Chemistry lessons. The theoretical framework focused on teaching goals and perspectives, laboratory work, science learning process, motivation and self-efficiency. The methodological guidelines are qualitative and descriptive.The study was targeted on two classes of learners in the 8th grade, in a school situated on the southern bank of the river Tagus and a research-based didactic proposal whose aim was to teach Chemical Reactions. To collected data, the teacher: (i) recorded what students said while doing research in groups, (ii) the reports written doing research activities, (iii) three questionnaires and direct observation. At the first stage a transcript of the recorded lessons was made. The next step was to analyse both the contents of the written documents produced by the students and of the transcripts. At a third stage, the teacher carried out a statistical analysis of the questionnaires. The results show that research-based strategies in Chemistry lessons favour: (i) the development of competences, (ii) students commitment, (iii) a changing intrinsic and extrinsic motivation and self. Efficiency and (iv) knowledge acquisition. The results of this study suggest that teachers training programmes either initial teacher training or continuing professional development should develop a different approach to learning process focused on the development of competences and research. This study was crucial to the teacher as it has contributed to her professional development and to the awareness of the need to reflect upon her own teaching methods as well as the growing importance of research in the teaching process.
