Analisa-se, em primeiro lugar, as aprendizagens de crianças dos três aos seis anos no domínio das ciências físicas, para, posteriormente, definir-se as actividades laboratoriais do tipo Prevê-Observa-Explica-Reflecte (POER) e se enquadrar o seu contributo na aprendizagem das ciências físicas. Seis Educadoras de Infância exploraram a temática da luz com oitenta e nove crianças dos três aos seis anos. Como resultados apresentam-se as respostas e representações das crianças como forma de evidenciar as suas aprendizagens. Como conclusão destas explorações analisam-se as vantagens na exploração deste tipo de actividades laboratoriais com crianças desta faixa etária.

The importance of STEAM education in preparing students to deal with societal challenges is nowadays an international recommendation. We may find different perspectives concerning STEAM education and the integration of its disciplines. A possible pathway to achieve a balanced integration is through Engineering Design (ED), starting from problems of reality that enable the articulated mobilization of concepts from various disciplinary areas, promoting interdisciplinary where teamwork and context play a fundamental role. This article reports a study with primary preservice teachers (6–12 years old) that aims to analyze the learning displayed and the difficulties underlying the usage of ED in solving STEAM problems. The participants were 45 preservice teachers. We adopted a qualitative methodology, and data were collected through observation, documents, artifacts, and photos. The preliminary results show a very positive reaction of the participants to the experience of solving real context problems collaboratively and mobilizing mathematical and physical science concepts in an integrated way. We identified active engagement, persistence, and motivation in the creation of a model that fulfilled the requested conditions. Difficulties were evidenced in the identification of some concepts and the mobilization of adequate scientific language in the argumentation of decisions.

A possible pathway to achieve disciplinary integration is through the use of the Engineering Design (ED) process, starting with problems in a real context that enable the mobilization of concepts from various disciplinary areas. The study reported in this paper aims to analyze the performance underlying the use of the ED process in solving authentic problems in a STEAM perspective, with future teachers of elementary education. We adopted a qualitative and interpretative methodology, with an exploratory design, where data were collected through participant observation, documents, artefacts and photographic records. The results are discussed, taking into account previous research and the data collected throughout the classes, where future teachers solved a problem task and created an artefact and a poster. Preliminary results show that the participants valued the experience and were actively engaged, showing persistence and motivation in solving the problem in a collaborative way, through the different steps of the ED cycle. This approach constituted an opportunity to favor the establishment of connections between different areas, such as mathematics, sciences or arts, detecting the possibility of integrating previously learned concepts. Difficulties were evidenced in the identification of some underlying mathematical and physical sciences concepts, particularly in the mobilization of an adequate scientific language while arguing and making decisions, or in accurately justifying the need to improve the designed plan.
