“…Similar results have been found in the literature where problems to be solved are not always given to students. According to Gomes, Borges, and Justi (2008), it is important that students know the aim of an experiment before doing it. For this purpose, first-year chemistry practical manuals from 17 universities in England and Wales were analysed (Meester & Maskill, 1995).…”

Supported by the French Ministry of ResearchInternational audienceMany studies have stressed students' lack of understanding of experiments in laboratories. Some researchers suggest that if students design parts of, or entire experiments as part of an inquiry-based approach, it would overcome certain difficulties. Experimental design implies to write a procedure. The aim of this paper is to describe the characteristics of a procedure in science laboratories. As a starting point, this paper proposes a model in the form of a hierarchical task diagram that gives the general structure of any procedure. This model allows both analysing existing procedure and designing new inquiry-based approach. The obtained characteristics are further organized into criteria that can help both teachers and students assess a procedure during and after its writing. These results were attained through two different sets of data. First, the characteristics of procedures were established by analysing laboratory manuals. This allowed defining the organization and type of information in procedures in educational context. This analysis revealed that students are seldom asked to write a full procedure, but sometimes have to specify tasks within the procedure. Secondly, iterative interviews were undertaken with teachers. This led to the list of criteria to evaluate the procedure

“…This is because identifying a question plays such a powerful role in giving meaning and direction to what follows (Howes, Lim, & Campos, 2009;Kuhn, 2007). There is also a relationship between the learners' understanding of the investigation question and their performance when conducting it (Gomes, Borges, & Justi, 2008). According to Chin and Osborne (2008) investigation questions do not emerge spontaneously from learners, and teachers have to employ strategies to elicit them.…”

This report describes how teachers support ninth-grade students who are doing scientific investigations in Natural Sciences in South African schools. This is of interest as allowing students to participate in inquiry-based investigations is a significant shift from traditional practices. It presents a new challenge to teachers as it signals an opportunity to shift from a teacher-centred to a student-centred approach in practical inquiry. The research study adopted a mixed methodology research design that involved the collection of both quantitative and qualitative data. The quantitative data were collected by means of questionnaires that were administered to 55 teachers. Qualitative data were collected by means of five classroom observations of student investigations and in-depth teacher interviews. The analysis of all the data revealed that teachers believe in providing support and not allowing learners to discover for themselves when participating in investigations. Teachers use a number of support strategies depending on the stage of the investigation. Based on these findings, a learning progression of teacher support for increasing learner autonomy was formulated which teachers can use in guiding them in the use of appropriate support strategies as they shift students towards greater autonomy in doing investigations.

“…Conhecer o experimento original, os fatos relacionados a ele e quando foi realizado pela primeira vez pode elucidar muitos aspectos do trabalho científico e as fragilidades das teorias. Este tipo de atividade experimental também auxiliaria no desenvolvimento de capacidades argumentativas e de resolução de problemas (inquirybased), enfatizando a provisoriedade do conhecimento científico [3].…”

Apesar das várias controvérsias, o experimento das pás de Joule é considerado um experimento crucial para demonstrar a conservação da energia em sala de aula. Entretanto, na apresentação do experimento, muito da sua complexidade à época da sua execução é negligenciada e apresenta-se apenas o resultado final, desperdiçando um momento excelente para discutir com os estudantes todas as hipóteses e sutilezas envolvidas. Neste trabalho apresentamos o processo de reprodução utilizando materiais atuais de um experimento similar ao de Joule de 1850 em busca do equivalente mecânico do calor. As hipóteses levantadas na replicação do experimento bem como a análise dos dados obtidos mostram a complexidade da ciência, o papel da experimentação na validação de teorias e um aspecto conceitual muito importante como a dificuldade para estabelecer um valor exato do equivalente mecânico do calor. Nossa intenção é mostrar como experimentos históricos podem colaborar para transformar a atividade experimental em sala de aula num ambiente rico para a argumentação e problematização.
