In the paper, we present a study devoted to the utilization of multiple-solution tasks (MSTs) in combinatorics as a part of a pre-service teachers course on didactics of mathematics from the view of the mathematics teachers’ specialized knowledge (MTSK) theoretical framework. The study was carried out over the standard course of a summer semester in 2021. The course was attended by 13 pre-service teachers (PSTs). It was carried out online, due to COVID-19 restrictions. Ten combinatorial multiple-solution tasks were assigned to the PSTs. Analyzing pre-service teachers solutions to these tasks, we sought the description and better understanding of the combinatorial knowledge of the topic from the perspective of MSTK. The results revealed some critical aspects of mathematical knowledge in combinatorics that pre-service teachers education should focus on.

 Resumen: En este trabajo reflexionamos sobre el conocimiento profesional del profesor de Educación Infantil en relación con la resta. La atención al conocimiento deseable de este profesional es relativamente reciente, existiendo escasos estudios que aborden este tema. Partimos de la consideración de que este conocimiento es especializado; diferente al del profesor de Primaria o Secundaria; y su caracterización debe realizarse desde un enfoque centrado en la propia matemática. Esto nos lleva a considerar el modelo del Conocimiento Especializado del Profesor de Matemáticas (Mathematics Teachers’ Specialised Knowledge, MTSK) como herramienta teórica y analítica idónea para ofrecer una propuesta de elementos de conocimiento especializado que, a la luz de nuestra experiencia docente e investigadora, consideramos que deseables para este profesional en relación con la resta, incluyendo aspectos de conocimiento del contenido (Mathematical Knowledge, MK) y de conocimiento didáctico del contenido (Pedagogical Content Knowledge, PCK). La reflexión sobre esta propuesta nos lleva a destacar tres elementos principales que parecen caracterizadores de la naturaleza de este conocimiento: su densidad y cohesión, la profundidad de los conocimientos matemáticos implicados y su repercusión para construir un adecuado PCK; y la relevancia del conocimiento de las fases que los niños siguen en su proceso de comprensión del número. Se aportan sugerencias para la formación inicial y continua de estos profesionales.Palabras clave: Conocimiento especializado del profesor de matemáticas. MTSK. Profesor de Educación Infantil. Resta.

Paying attention to this professional desirable knowledge is relatively recent, and thus there are few studies that address it. We assume as a starting point the consideration that this knowledge is specialized; differs from that of primary or secondary teachers’; and its characterization must be carried out from an approach centered on mathematics itself. This leads us to consider the model of Mathematics Teachers’ Specialised Knowledge (MTSK) as a suitable theoretical and analytical tool to offer a proposal of specialized knowledge elements that, in light of our teaching and research experience, we considered desirable for the work of teaching of these professionals in relation to subtraction. In this proposal we include aspects of Mathematical Knowledge (MK) and of Pedagogical Content knowledge (PCK). In the proposal we highlight three main elements that seem to characterize the nature of this knowledge: its density and cohesion; the depth of the mathematical knowledge involved and its impact to build an adequate PCK; and the relevance of knowledge of the phases that children follow in their process of understanding the number. Some recommendations for early years teachers’ education are provided.Keywords: Mathematics Teachers’ Specialised Knowledge. MTSK. Early childhood teacher. Subtraction. Mathematical knowledge. Pedagogical content knowledge.CONHECIMENTO ESPECIALIZADO DO PROFESSOR DA EDUCAÇÃO INFANTIL NO ÂMBITO DO TEMA DA SUBTRAÇÃO Resumo: Neste trabalho, refletimos sobre o conhecimento profissional do professor de Educação Infantil em relação à subtração. Considerar como foco de atenção o conhecimento desejável destes professores é algo relativamente recente, existindo poucos estudos que abordam esta questão. Partimos da consideração de que esse conhecimento é especializado; diferente do conhecimento do professor das etapas escolares seguintes; e sua caracterização deve ser realizada a partir de uma abordagem centrada na própria matemática. Nesse sentido consideramos a conceitualização do Mathematics Teachers’ Specialized Knowledge (MTSK) como uma ferramenta teórica e analítica para conceitualizar uma proposta de elementos constituintes do conhecimento especializado ideal do professor no âmbito que, à luz de nossa experiência de ensino e pesquisa, consideramos desejável para este profissional em relação à subtração. Nesta proposta incluímos aspectos do conhecimento do conteúdo e do conhecimento pedagógico do conteúdo (PCK). Nesta proposta destacamos três elementos principais que parecem caracterizar a natureza desse conhecimento: sua densidade e coesão; a profundidade do conhecimento matemático envolvido e seu impacto para construir um PCK adequado; e a relevância do conhecimento do professor das fases que as crianças seguem no seu processo de compreensão do número em etapas educativas posteriores. São fornecidas sugestões para a formação inicial e contínua de professores.Palavras chave: Conhecimento Especializado em Professores de Matemática. MTSK. Professor de Educação Infantil. Subtração.

In this study, we adapted the school sports day to provide opportunities to relate real-life situations with mathematical knowledge and skills. The purpose of this study was to describe the way that the teachers interact with their students and the students’ responses during mathematical modelling processes. The designing of the modelling task was inspired by the Realistic Fermi Problems about the bleacher in the school sports day. The modelling task was designed by a collaboration of mathematics teachers and educators and experimented with 10th-grade students. Each experiment lasted for 45 minutes and was conducted in the one-day camp with 45 students. The results showed that the students who had no previous experience of mathematical modelling engaged in mathematical modelling processes with their friends under the guidance and supporting of the teacher. Most of them were able to think, make assumptions, collect data, observe, make conjectures and create mathematical models to understand and solve the modelling task.

Although the title of this book implies a target audience of math-anxious people, it is equally, if not more, suitable for teachers of mathematics and mathematics educators. Do You Panic about Maths? Coping with Maths Anxiety attempts to build a model of the interaction between reason and emotion to explain the behavior of adults anxious about mathematics. The model was derived from a qualitative study of adults that had three components: hour-long interviews with two dozen people; 36 2-hour sessions with a group of four women and three men; and individual in-depth interviews, consisting of 12 or 24 sessions, with three women. Buxton relates his model to the work of Skemp, with whom he has collaborated. Indeed, he has extended Skemp's (1979) model of intelligence in this book. In addition to the theoretical framework he discusses, Buxton provides some ideas for coping with one's mathematics anxiety and gives suggestions for mathematics teachers about how to teach to avoid or combat students' anxiety.

AbstrakSelf-efficacy calon guru matematika masih kurang. Oleh karena itu, perlu dilakukan analisis mengenai self-efficacy calon guru matematika sehingga dapat diketahui aspek self-efficacy yang perlu ditingkatkan. Tujuan penelitian ini yaitu untuk menganalisis self-efficacy calon guru matematika dalam mengajar matematika. Metode penelitian yang digunakan yaitu kualitatif dengan menggunakan teknik purposive sampling. Sampel yang diambil sebanyak tiga orang calon guru matematika jurusan pendidikan matematika di Institut Pendidikan Indonesia. Analisis data dilakukan secara kualitatif. Hasil penelitian menunjukkan bahwa calon guru matematika memiliki keyakinan dalam penguasaan pengetahuan matematika, namun merasa kurang yakin bahwa dirinya mampu untuk menyampaikan materi matematika kepada siswa. Kurangnya keyakinan ini berakibat pada kemampuan pedagogis calon guru matematika.  Self-Efficacy of Mathematics Prospective TeachersAbstractThe self-efficacy of prospective mathematics teachers is still lacking. Therefore, it is necessary to analyze the self-efficacy of prospective mathematics teachers so that it can be seen which aspects of self-efficacy need to be improved. The purpose of this study was to analyze the self-efficacy of prospective mathematics teachers in teaching mathematics. The research method used is qualitative by using a purposive sampling technique. The sample taken was three prospective mathematics teachers majoring in mathematics education at the Indonesian Institute of Education. The data analysis was done qualitatively. The results showed that the prospective mathematics teacher had confidence in the mastery of mathematical knowledge, but felt less confident that he was able to convey mathematics material to students. This lack of confidence results in the pedagogical abilities of prospective mathematics teachers.
