We present two sets of lessons on the history of mathematics designed for prospective teachers: (1) Euclid's Theory of Area, and (2) Euclid's Theory of Similar Figures. They aim to encourage students to think of mathematics by way of analysis of historical texts. Their historical content includes Euclid's Elements, Books I, II, and VI. The mathematical meaning of the discussed propositions is simple...
Good preparation of students to the profession of teacher is very important. In my research I focus on improving the quality of teacher's preparation at the university level, and through it at school level in the future. I present the proposal of teaching mathematics with the use of algorithmisation. It is possible, because solutions to many mathematical problems can be expressed in the form of an...
The purpose of this essay is not to answer the question posed in the title, but to specify the ''preconditions'' for the defense of two opposing stances: mathematical culturalism and mathematical anticulturalism. The names of these stances are not present in the source literature. Introducing them to the debate on the nature of the relationship between expert mathematical knowledge and its folk counterpart...
This short note is devoted to the role played by intuitive explanations in mathematical education. We provide a few examples of such explanations. They are related to: verbal commentaries, perception, physical models. We recall also some examples of internal explanations, inside mathematics itself.
This article draws on the work of Wittmann and his followers who conceived and developed the notion of substantial learning environment (SLE). The paper contains a proposal of a teaching unit based on the definition of Factorial Number System (FNS). First, we illustrate the process of conversion from FNS to the Decimal Number System (DNS) and back. Secondly, we provide theorems on the divisibility...
This paper draws on data from semi-structured interviews undertaken with year one teachers in England and Sweden. The broad aim was to explore how teachers construe their own and parents' roles in supporting year one children's learning of early number. The role of homework within those efforts, surfaced as a key theme. The two data sets were an\-a\-lysed independently by means of a~constant comparison...
The article concerns the research on students' perception of visual structures in van Hiele's sense (1986). The empirical % 1986 studies described in the paper make use of a combined methodology -- eye-tracking and a written study questionnaire. There was an analysis of the results of 14 pupils in the paper the 1st grade of a middle school and 19 pupils from a secondary school. The subjects were shown...
Stereotypes concerning women's mathematical abilities are widespread and can become an obstacle for some women to succeed in this domain, thus, they can be one of the possible reasons for the gap between men and women in mathematics. There is significant empirical evidence confirming that women in the situation of stereotype threat (i.e. when they are afraid of confirming that they are less gifted...
The main goal of the following article is to design an improved version of the negotiation game created by prof. Alan Fowler (Fowler, 1997). I have tried to achieve this by constructing four separate versions of the game which represent different approaches while preserving rules, chosen basic technical assumptions and the simplicity of the base game. Each version of the game is supposed to i.a. make...
The use of signs in the teaching of mathematics plays a crucial role in students' cognition. Trying to understand what signs both students and teachers use in the mathematics classes may help us understand their meaning making processes. From this point of view, this paper aims to reveal the use of semiotic resources both by students and a teacher while lecturing Cartesian plane in seventh grade level...
Individuals diagnosed with Autism Spectrum Disorder (ASD), the fastest growing disability group, exhibit varying degrees of intellectual ability. Students with ASD are increasingly held accountable to academic standards comparable to their peers. Applied Behavior Analysis (ABA) is widely considered best practice for supporting these students. Twenty-six single-case design (SCD) mathematics classroom...
The results of Zarzycki for the cardinality of the sets of all bijections, surjections, and injections are generalized to the case when the domains and codomains are infinite and different. The elementary proofs the cardinality of the sets of bijections and surjections are given within the framework of the Zermelo-Fraenkel set theory with the axiom of choice. The case of the set of all injections...
Teoria pola po raz pierwszy została opisana w pracy Chou, Gao, Zhang w 1994 roku. W kolejnej pracy (Janicic, Narboux, Quaresma 2012) zaprezentowano nowy system aksjomatów teorii pola i program przeznaczony do automatycznego dowodzenia twierdzen. W artykule chcemy przedstawić interpretację teorii pola w geometrii analitycznej na płaszczyznie kartezjanskiej R×R z porządkiem leksykograficznym. Również...
We discuss the role of a heuristic principle known as the Principle of Permanence of Forms in the development of mathematics, especially in abstract algebra. We try to find some analogies in the development of modern formal logic. Finally, we add a few remarks on the use of the principle in question in mathematical education.
In this paper we explore different ways of solving quadratic equations. Our main goal is to review traditional textbooks methods and offer an alternative, often side-stepped method based on the area model. We conclude that whereas traditional methods offer effective algorithms that quickly lead to the desired results, alternative methods may enhance meaningful and joyful learning.
