    Future early childhood teachers designing problem-solving activities
    (Bandung Himpunan Matematika Indonesia (IndoMS) bekerjasama dengan Program S2 Pendidikan Matematika, FKIP, Universitas Sriwijaya Palembang, 2022-06) Sala-Sebastià, Gemma; Breda, Adriana; Farsani, Danyal
    This work aims to identify the criteria to design activities based on problem solving tasks that emerge when future early childhood education teachers jointly plan their activities and reflect on them. The participants were 76 students from the Didactics of mathematics subject that was carried out in the 2nd year of the Early Childhood Education Degree of a Catalan public university. This is qualitative research in which the phases of the thematic analysis have been adapted: familiarizing with the data; systematically applying the categories to identify the student criteria emerged; triangulating the analysis with experts; reviewing and discussing the results. The Didactic Suitability Criteria (DSC), from the Ontosemiotic approach (OSA) framework to design tasks and their indicators, were used to categorise and analyse the tasks performed by future teachers. As a result, it was identified that when the future teachers adopt consensually design their activities, they are implicitly based on the Didactic Suitability Criteria (DSC). Still, not all their indicators emerge since their reflection is spontaneous and is not guided by an explicit guideline that serves them to show their didactic analysis in detail. The study concludes that it would be convenient to offer future teachers a tool, such as DSC, to have explicit criteria to guide the designs of their mathematical tasks. In this sense, a future line of research opens, much needed, to adapt the DSC to the singularities of this educational stage.

    Non-verbal interaction and students’ visual engagement in mathematics and English classes
    (Universidade Luterana do Brasil, 2022-07) Farsani, Danyal; Breda, Adriana; Sala-Sebastià, Gemma
    Background: The interactions in the classroom are of particular interest to the teaching and learning processes. Objectives: This study examines nonverbal interaction in mathematics classrooms, and how different modes of nonverbalbehaviour, contributed to the engagement in lessons. Design: A quantitative study. Setting and Participants: 30 randomly selected students wore mini camera-mounted eyeglasses in their mathematics and English lessons. Approximately 45 hours of video recording were made from these cameras (from a first-person’s perspective) to analyse and compare the nonverbal interaction in mathematics and English lessons. Data collection and analysis: In Google Images, we objectively searched and statistically analysed frames in which the class teachers appeared within the students’ visual field. Results: The results show that how students are visually engaged with the teacher depends on a set of proxemics. Differences were found related to visual attention both regarding the subject matter and the different proxemics of the student in relation to the teacher, pointing out that students are more visually involved with the teachers’ instructions when at a proxemic of 1.20 to 3.70 meters. Furthermore, we report differences between boys and girls and how they are visually engaged in their mathematics classrooms. Conclusions: Finally, we report how teachers pointing gestures can serve as a tool to recapture students’ visual attention in mathematics classrooms.

    Reflections of future kindergarten teachers on the design of didactic sequences with the use of robots
    (Modestus, 2022-08) Seckel, María José; Breda, Adriana; Farsani, Danyal; Parra, José
    The purpose of this study is to analyze the reflections of future kindergarten teachers when designing didactic sequences with the use of the bee-bot robot. A qualitative methodological design was followed to achieve this objective, collecting the data through a written record prepared by the participants from collaborative work. A total of 25 future teachers participated, forming six working groups. The data were analyzed with the content analysis technique, considering the criteria of didactic suitability–epistemic, cognitive, interactional, mediational, affective, and ecological–and their respective components. The results suggest that at the moment prior to the design of the didactic sequences, the reflections of the groups of future teachers are related only to some criteria, while, in the design of the proposed teaching and learning process, the units of analysis were related to all six criteria. With the results obtained, it is concluded that a future implementation and observation of the design of didactic sequences by the participants would allow the participants to consider more components of the criteria when reflecting. In addition, it is concluded that training that contemplates the criteria of didactic suitability, would also allow future teachers to deepen their reflections, guiding them with these tools.

    Teaching and learning of mathematics and criteria for its improvement from the perspective of future teachers: a view from the ontosemiotic approach.
    (City University of New York, 2021) Breda, Adriana; Seckel, María José; Farsani, Danyal; Fernandes da Silva, José; Calle, Eulalia
    The objective of this article is to identify the meaning attributed to the didactics of mathematics and what are the criteria with which an improvement in the teaching and learning process of mathematics is based, future teachers of mathematics, belonging to universities in three different countries (Brazil, Chile, and Ecuador). The qualitative analysis indicates that the majority of future teachers consider that the didactics of mathematics is a technical discipline that consists of providing strategies, resources, and procedures for teaching mathematics; few consider it as an art to teaching and almost none consider it as a scientific discipline that is concerned with studying the processes of teaching and learning mathematics. In addition, the results show that the criteria used by them, on how teaching and learning in this discipline can be improved, are focus, above all, in the cognitive, ecological, and emotional aspects and, to a lesser extent, to the interactional, mediational and epistemic. Finally, it is concluded that the improvement in teaching and learning is directly related to an improvement in the training programs of future mathematics teachers.
