The STE(A)M approach has been recognized by several authors for its potential in assisting teaching and learning, and several curriculum standards already value its application in the classroom [1]. This approach is based on the articulation between different areas, the clarification, and the deepening of the concepts being studied. Although there are different approaches, according to the fields involved, STEM and STEAM are two among the most often mentioned in the literature. STEM is based on learning that integrates the following areas of knowledge: Science, Technology, Engineering, and Mathematics. The conceptualization of the STE(A)M approach is not consensual and uniform. There are different models focusing on problem-solving based learning, project-based-learning, design-based learning, and engineering models. Still, different authors [3] [4] [5] present different conceptualizations of this approach. In this paper, we relied on the existing literature to discuss the different understandings of the STE(A)M approach. We will also pay attention to mathematics and how different authors see the disciplines’ role within a STE(A)M approach and discuss the evolution of the mentioned authors’ positions throughout time. Thus, methodologically, we undertook the following steps: (i) literature search based on the selected keywords; (ii) selection of the texts, considering the authors and time gap, in order to analyze the evolution of the research and (iii) collection and organization of the relevant topics for the study. This study aims to present the meanings, conceptualizations, and possible influences present in different models and for understand the evolution of the STEM and STEAM approaches over time. The main findings suggest a focus on the interdisciplinary or transdisciplinary approach as opposed to the primeval years of investigations in STEM and STEAM when many authors advocated a multidisciplinary approach. This change in thinking is due to the need to train students in an integral and holistic manner, developing citizens with transversal knowledge and skills prepared for the current societal challenges.

Research has highlighted the potential of technology to transform the teaching of Mathematics, but also the relevance of teachers and their professional knowledge. In this article, a qualitative methodology is adopted and two episodes of the practice of one teacher are analyzed in the scope of the study of functions in the 10th grade, based on the model of Knowledge for Teaching Mathematics with Technology (KTMT). The goal is to characterize the teacher's knowledge from her practice, simultaneously understanding how this contributes to promoting the development of the teacher's knowledge. The conclusions reached show the importance of including in the KTMT conception aspects highlighted by the research on technology integration. These aspects are determinant to characterize the teacher's knowledge. They also show the relevance of the practice for the development of the teacher's knowledge and the dynamic character of the vision of knowledge offered by KTMT. La investigación ha puesto de relieve el potencial de la tecnología para transformar la enseñanza de las matemáticas, pero también la relevancia de los docentes y sus conocimientos profesionales. Este artículo adopta una metodología cualitativa y analiza dos episodios de la práctica docente en el contexto del estudio de funciones en el décimo grado, basado en el Modelo de Conocimiento para la Enseñanza de las Matemáticas con Tecnología (KTMT). La intención es caracterizar el conocimiento del docente desde su práctica, entendiendo simultáneamente cómo esto contribuye a promover el desarrollo del conocimiento. Las conclusiones alcanzadas muestran la importancia del modelo KTMT incluir en su concepción aspectos destacados por la investigación sobre la integración de la tecnología, determinantes en la caracterización del conocimiento del docente. También muestran la relevancia de la práctica para el desarrollo del conocimiento del docente y la perspectiva dinámica sobre el conocimiento que este modelo puede proporcionar. A investigação tem evidenciado o potencial da tecnologia para transformar o ensino da Matemática, mas também a relevância do professor e do seu conhecimento profissional. Neste artigo adota-se uma metodologia qualitativa, com base em estudo de caso, e analisam-se dois episódios da prática de uma professora no âmbito do estudo de funções no 10.º ano de escolaridade, tendo por base o modelo do Conhecimento para Ensinar Matemática com a Tecnologia (KTMT). A intenção é caracterizar o conhecimento da professora a partir da sua prática, compreendendo simultaneamente como esta contribui para promover o desenvolvimento do conhecimento da professora. As conclusões alcançadas evidenciam a importância do modelo KTMT incluir na sua concepção aspetos realçados pela investigação sobre integração da tecnologia, determinantes na caracterização do conhecimento da professora. Mostram ainda a relevância da prática para o desenvolvimento do conhecimento da professora e a perspectiva dinâmica sobre o conhecimento que este modelo pode proporcionar.

Using technology to get a graphical representation of functions requires the choice of a suitable viewing window. The literature suggests teachers' knowledge as being central in this process, but does not tell us much about how the teachers should manage this. This study aims to improve understanding about the teachers' choices related to the viewing window on the study of functions. It also intends to illustrate how this analysis can be a useful way to access aspects of teachers' knowledge based on the framework of Knowledge for Teaching Mathematics with Technology (KTMT). The study adopts a qualitative methodological approach, undertaking case studies of two teachers. The findings recognize the importance of carefully sequencing the students' contact with this kind of situation and the impact of the viewing window over the teachers' choices of tasks, pointing to the relevance of considering situations where the students actually face the difficulties. This highlights the relation of teachers' choices of viewing window to their knowledge of different KTMT's domains, and specifically the relevance of knowledge of different ways to change the window; of the difficulties faced by the students; of the most suitable tasks (and required viewing window) at each moment; of the impact of the viewing window on the appearance of a graph and of the different situations associated, from the mathematical point of view.

This work intends to contribute to understand how pupils use the graphic calculator in mathematics classroom and to increase the knowledge about this use. The methodology adopted followed a case study approach. The participants were three 10th grade pupils. Data analysis shows that these pupils don’t know the graphic calculator very well, and that they don’t mind about that. They use it mainly to draw graphics and to solve equations and inequations, taking a small profit from the calculator’s potentialities. Pupils’ main difficulties are related to the interpretation of information given by the graphic calculator. These findings appear to be related to teacher’s practice, especially regarding his attention to pupils’ use of the graphic calculator and the type of tasks he proposes in the classroom., Este trabalho procura contribuir para o conhecimento e a compreensão da forma como os alunos utilizam a calculadora gráfica na aprendizagem da Matemática. A metodologia adoptada é de estudo de caso, sendo os participantes três alunos do 10º ano de escolaridade. A análise dos dados sugere que os alunos não possuem um conhecimento profundo sobre a calculadora, aspecto que de resto não valorizam. Aponta ainda para um recurso à máquina essencialmente para traçar gráficos e resolver equações/inequações, com um aproveitamento das potencialidades da tecnologia que fica aquém do que seria de esperar. A interpretação da informação veiculada pela máquina surge como a grande dificuldade que os alunos têm que enfrentar. Associada a estes aspectos surge a actuação do professor e, nomeadamente, a atenção que este dá à utilização que os alunos fazem da calculadora e o género de tarefas que propõe.
