- Conceções de Professores do Ensino Básico sobre a Prova Matemática: influência da experiência profissionalPublication . Viseu, Floriano; Menezes, Luís; Fernandes, José António; Gomes, Alexandra; Martins, Paula MendesProof is an activity that plays a key role in the construction of mathematical knowledge, which is why it acquires relevance in mathematics programs. Admitting that teachers' conceptions about proof influence how it is handled in the classroom, we tried to investigate the conceptions of Portuguese mathematics teachers from the 3rd cycle of basic education (grade 7 to 9) on different aspects of mathematical proof and the relationship that the teachers’ experience has in these conceptions. Adopting a mixed methodological approach, we collected data through a questionnaire answered by 72 teachers, and an interview with two teachers with different professional experience. The results show that teachers, especially those with less experience, consider that mathematical proof has a distinct nature from other disciplines, it is an essential activity for the construction of mathematical knowledge and its function is to verify and explain the truth of a statement by developing reasoning and mathematical communication. With respect to student participation in the activity of proving, teachers with more teaching experience are the ones that most highlight it, which allows students to realize the nature of this activity. In curriculum terms, teachers with less experience are the ones that most agree with the presence of proof in early grades, while emphasizing that this activity only makes sense in some program topics.
- Perspectivas de Professores de Matemática sobre o Humor e o seu Valor EducacionalPublication . Menezes, Luís; Fernandes, José António; Viseu, Floriano; Ribeiro, António Augusto Gaspar; Flores, PabloAt present, humour has an increasing acceptance and appreciation, because we recognize the positive contributions to the well-being of people in contexts as diverse as health, business, and entertainment. What happens in Education and, in particular, in Mathematics teaching? To answer this question, we designed this quantitative study with a sample of 1088 Iberian mathematics teachers (Portuguese and Spanish), that teach from the early years through to higher education. Through the use of a questionnaire, we seek to find out if Portuguese and Spanish teachers who teach Mathematics, throughout the various levels of education, appreciate humor, what perspective they have of it and its educational value, and if they use it in teaching the discipline. The study also sought to determine if the teaching level in which teachers teach mathematics has an influence on the perception and use of humor for instructional purposes. The study also investigates if there are any significant differences between Portuguese and Spanish teachers in relation to these aspects. The results show that the overwhelming majority of teachers, at all levels of teaching, recognize the meaning of humor, consider that they have a sense of humor, justify its use in mathematics teaching and have already seen it being used or used it in their classes, with the goal of creating a good learning environment and making students think. The study reveals differences among teachers at different levels of teaching, indicating that there is a greater predisposition of teachers in the initial years, in comparison to other years, to value and use humor in mathematics teaching. The study also reveals differences between Portuguese and Spanish teachers, with Portuguese presenting a higher average agreement in most items.
