“…To analyse this activity, we selected events from a video 14 of 17 minutes and 46 seconds obtained from the screen recording 15 (Bairral et al, 2022) of the smartphone used by students GD (12 years old) and MV (13 years old). The analysis looked for elements in the subjects' touches and speeches (writings, audios, screen constructions, etc.)…”

Background: Visualisation is a crucial skill for several everyday life activities and conceptual construction and development. Objectives: As it represents a substantial part of Euclidean geometry, this article addresses: the study and analysis of the relationships between angles formed from two parallel lines intersected by a transversal and the role of visualisation in the construction and development of geometric concepts imbricated in the mathematical relationships underlying the theme. Design: The methodological approach adopted was Design Experiments. Settings and participants: A teaching situation is presented, in which students from the 8th grade of elementary school at a state public school in Rio de Janeiro, Brazil, performed manipulations on the smartphone screen while carrying out an activity. Data collection and analysis: To analyse this activity, we selected events from a video obtained from the smartphone used by the students. Results: Through interactions and handlings, students visualised, analysed, and built the concepts of corresponding angles and collateral angles by studying a geometric object on the smartphone screen through the GeoGebra application. Conclusions: The geometric work mediated by mobile devices with touch screens enables the curricular reorganisation of Geometry and the articulation and the breaking of the hierarchy of concepts.

“…In order to explore the use of SPs in online settings, data collection for this study included screen recordings created with screen-recording software (APowerSoft or any similar software of the student's choice). This collection method has been used in previous studies [26,27]. Recording of a screen is a rather invasive method of data collection that can make it difficult to find willing participants [28,29].…”

The goal of science education has shifted from teaching scientific concepts to facilitating students’ active role in making sense of phenomena through engaging in scientific practices (SPs). While engaging in scientific practices, students use and develop core ideas. The COVID-19 pandemic forced a shift towards online education, stressing the need to explore how SPs are used in a remote setting. This study aimed to investigate upper secondary students’ use of SPs during collaborative work in a remote setting. The study was conducted in two stages. In Stage 1, the researcher designed collaborative assignments according to the SP approach. In Stage 2, students (N = 16) worked on the designed assignments in small groups. Students’ actions on the computer were recorded with screen-recording software and investigated from three perspectives: use of digital resources, use of SPs, and collaboration. Interviews were conducted to understand students’ perceptions and engagement and were analysed by content analysis means. The results indicated that the collaboration actions were intertwined with SPs use and use of digital resources. The challenges faced by students varied by SPs, with developing models and constructing scientific explanations causing the most challenges. We discuss possible strategies to engage students in SPs in online settings.
