The implementation of an integrated approach of STEM education with real-life scenarios is crucial to motivate students to learn and to better prepare them for real-world challenges, which is a big challenge for teachers. Therefore, there are implications for teaching practice and consequently the need for professional development. This paper presents an integrated approach of STEM education developed in the context of a collaborative professional development programme implemented in an exclusive online context, provoked by the COVID-19 pandemic. The programme aimed at providing teachers with knowledge and skills to develop STEM integrated tasks to be implemented in class. This study used a quantitative–qualitative approach to answer the research questions, using mixed methods to collect data. Participants are primary school teachers who participated in the programme during four months in the school year 2020/2021. Based on data collected from questionnaires, participant observation and teachers’ final reports, it was verified that teachers recognized the importance of obtaining training in STEM education and that this type of professional development was very relevant and improved their knowledge and skills to implement STEM hands-on practices in class. In addition, a case study of a science and mathematics 6th grade teacher is presented to illustrate how she implement integrated STEM tasks in class based on a real-world scenario such as the COVID-19 pandemic. Finally, teachers recognized the importance of this approach and that it increases students’ motivation to learn.

In the field of physics teaching, the simple pendulum provides a very simple way to study the harmonic oscillator, the source of some fundamental concepts such as periodicity, relaxation time and anharmonicity. As such, its experimental study is frequently integrated into high school or first year university programs. With this in mind, in this article, we propose a simple setup allowing the study of some of its properties. By coupling a small wireless acquisition board to an oscillating mass, the centripetal acceleration is recorded and analyzed. We show using basic calculations how this acceleration allows us to extract the variation with time of its period and of the amplitude. The experimental results show that the damping of the amplitude is very well described by an exponential law. The accuracy we obtain on the period allows us to show that, not only does it decrease with amplitude, but that this decrease is relatively well described by standard calculation. Using wireless multipurpose acquisition board and usual spreadsheet for experimental modelling, the completion of this work, about 4 h, offers to the student an original way to go a little beyond the classical study of the spectacular object that is the pendulum.

A teaching approach aiming at an epistemologically balanced integration of computational modelling in science and mathematics education is presented. The approach is based on interactive engagement learning activities built around computational modelling experiments that span the range of different kinds of modelling from explorative to expressive modelling. The activities are designed to make a progressive introduction to scientific computation without requiring prior development of a working knowledge of programming, generate and foster the resolution of cognitive conflicts in the understanding of scientific and mathematical concepts and promote performative competency in the manipulation of different and complementary representations of mathematical models. The activities are supported by interactive PDF documents which explain the fundamental concepts, methods and reasoning processes using text, images and embedded movies, and include free space for multimedia enriched student modelling reports and teacher feedback. To illustrate, an example from physics implemented in the Modellus environment and tested in undergraduate university general physics and biophysics courses is discussed.
