“Kyozai-Kenkyu” is an essential part of Japanese lesson study and involves task design for classroom lessons. Most of Japanese teachers often refer to textbooks as a main resource in doing “Kyozai-Kenkyu”. However, there are different kinds of use with regard to different approaches to knowledge at stake. In this study, we aim to examine teachers’ paradidactic activities related to...

Textbooks, which still are one of the most used tools in the mathematics classroom worldwide have a substantial impact on the production of students’ subjectivities. In this sense, despite research showing that there is a need in eliminating gender bias in mathematics textbooks, they still reproduce the portrayal of what it means to be a girl/woman or a boy/man in our current society....

In primary schools around the world, mathematics textbooks are the most relevant medium for lesson preparation for the vast majority of teachers. Though the field of textbook research is constantly growing, our knowledge about textbook effects on students learning is still rather constrained. In this contribution, three studies are presented, which address that research gap for the field of...

We utilize four sampling methods (simple random sampling, systematic sampling, stratified random sampling, and cluster sampling) to select pages from ten textbooks, resulting in forty samples of pages. For each sample, we estimate the proportion of pages containing statistics tasks and the number of statistics tasks within each textbook. These estimates are compared with the actual values...

*Integrating history of mathematics into mathematics textbooks is a commonly accepted idea and practice in modern textbook development in China, and mathematicians are an integral part of mathematical history. So how do Chinese mathematics textbooks fare in this particular aspect? In this study, we investigate how mathematicians are represented in two series of primary and junior secondary...

Teachers are central actors in the interpretation and implementation processes of curricular resources. Holding this central position in the teaching and learning process of mathematics, teacher's interactions with curriculum resources are often studied in different stages and forms of interactions. In this study we focus on means of communication that teachers use to describe the narrative,...

In this contribution, we present a praxeological analysis of (introductory) tasks on vectors in German textbooks for secondary schools in the state North Rhine-Westphalia. We motivate our research concern from our interest in transition research from school to university and found a lack of research on vectors in this area. The Anthropological Theory of the Didactic (ATD) has already proven to...

We present a work in progress of a new method for textbook research based on the Anthropological Theory of Didactics (ATD). Representation of the concept of function is chosen as a particular example to validate how the praxeology and levels of didactic co-determination of ATD can be used for textbook research. Two different Norwegian textbooks published at different times are selected. The...

A challenging task when doing research about the use of mathematics textbooks is the comprehensible description of activity shown by students and their construction of knowledge when using the textbook. As argues Kadunz (2016), the semiotics of Charles S. Peirce seems to be a promising tool for fulfilling this task.

In this paper, we turn our attention to student’s inscriptions (e.g., their...

In this paper, we aim at identifying inclusive practises in inclusive maths lessons. Based on the textbook “Das Zahlenbuch” and the accompanying artefacts, the lessons should offer occasions for all children to participate in and benefit from the learning situation. In our study, we analyse videographed lessons, considering the ideas of sensitivity of differences, language and materials and...

In Germany, primary school children should learn to not only execute the subtraction algorithm. They should also understand why the algorithm works. But this understanding is hard to achieve because the description of these processes is dominated by many technical terms and phrases like: “Unbundle one ten to ten ones. Reduce the number of tens…” – in this case for the subtraction algorithm...

Currently, too few students, including those in underrepresented groups, are engaged in making sense of mathematics. Our curriculum and development research goals are to enhance student productive disciplinary engagement and learning through four design principles: problematizing, authority, accountability, and resources (Engle, 2011). Examining student behaviors, participations, and...

The aim of this research is to design age-appropriate curriculum to nurture children’s mental operations ability and to clarify these effects through concrete classroom-based lessons.

I designed two lesson plans for grade4 students that nurtured children’s mental operations, and taught these in two classes. Two of the lesson plans were as follows.

1. The group 1 lesson was the same order in...

Textbooks are different in many ways. Not only the mathematical content differs even more the presentation and handling of mathematics show great varieties.

To explore the field and to identify the differences with statistical methods, an instrument for analysing textbooks was developed. This instrument focuses on the three main structural elements of textbooks: tasks, pictures and...

The concept of vector is a central part of mathematics and physics at school. Three approaches to the concept of vector can be distinguished: arrow classes, n-tuples and vector space axioms. In order to develop adequate conceptions of vectors, different facets of the concept should be presented to the students and the representation in the subjects mathematics and physics should be...

To be used in Mexican public schools, all mathematics textbooks have to pass an allegedly rigorous review process by Ministry of Public Education (Secretaría de Educación Pública). Nevertheless, various revisions of approved mathematics textbooks reveal many deficient features, going from orthographical, mathematical and contextual errors to inadequate learning sequences. The aim of this...

Ratio, rate and proportional relationships are arguably the most important topics in middle grades mathematics curriculum before algebra. However, many teachers find these topics challenging to teach and students find them difficult to learn.

the nature of mathematical discourse. Signs are carriers of cultural conventions and

Semiotics helps to understand the way in which individuals think and communicate

with signs in a cultural context. Duval's theory of semiotic representations...

The utilization of textbooks by mathematics teachers has been the subject of many recent studies; students’ opinions, however, have not received such attention. The study presented in this paper aims to investigate both students’ and their teacher’s ways of and reasons for using the textbook, with an emphasis on the vertices of the Socio-Didactical Tetrahedron. The findings indicate that the...

As already known well, for learning geometry, students start from their own experience and concrete shapes; on the other hand, students have to leave from them for developing their geometric thinking (cf. van Hiele, 1958).

When we seen textbooks as (implemented) curriculum, textbook must help students’ this process.

For this background, our research question is: Are Japanese elementary school...

In the Undergraduate Teaching and Learning in Mathematics with Open Software and Textbooks (UTMOST, Beezer et al., 2018) project we study the use of open source computational resources in the teaching and learning of mathematics at undergraduate level. The project gathers (a) real-time, individualized viewing data from three dynamic undergraduate textbooks authored in textbooks authored in...

Proportional reasoning is an important skill that requires a long process of development and is a cornerstone at the middle school level. One of the reasons why students cannot demonstrate this skill at the desired level is the learning opportunities provided by the textbooks. The aim of this study examines the extent to which selected Turkish, Singaporean and Canadian middle school...

In mathematics teaching and learning, it is important for students to learn not only mathematical contents but also roles and functions of the contents. Functions of a hierarchical classifications are particularly related to mathematical definition and defining. The purpose of this paper is to clarify functions of a hierarchical classification of quadrilaterals in Japanese textbook. From the...

The integer numbers structure and the idea of equivalence are elementary in the mathematical construction of the ordered field of the rational numbers. Hence, the concept of equivalence should not be absent in the Elementary School´s classrooms and textbooks, and it should be well constructed with the students in the sense that they are able to answer the question ‘How can one decide if two...

Our work is part of a thesis that deals with university teachers’ practices, particularly the relation between research and teaching practices of university professors. We study this issue from the lens of interactions with resources (including textbooks). We choose graph theory as an object of study. Graph theory is a contemporary mathematical field, taught in several academic paths (computer...

In the arena of mathematics teaching and learning at undergraduate level, we strive to assess and evaluate the use of dynamics textbooks authored in PreTeXt. We seek to investigate how mathematical content in a textbook is taken up by instructors as they plan and teach their lessons, and by students who participate in those lessons. We analyze textbook raw content to identify competencies...

In the United States, teaching mathematics for social justice has the potential to make studying advanced mathematics more accessible to students coming from low income and historically underrepresented ethnic groups. Gutstein’s (2005) work on teaching students to “read” and “write” the world with mathematics laid the foundation for the framework that will be used in this middle school...

To understand current state of the research on the representation of textbooks, 170 articles on mathematical representation are randomly selected to explore the research objects in recent decades, with the result of only 10.6% papers focusing on mathematics textbooks. Then, those papers are analyzed in terms of research questions, theoretical frameworks and research methods. Results show that...

The Dutch reform movement towards Realistic Mathematics Education (RME) started at the end of the 1960s. As an alternative for the then prevailing mechanistic approach, tasks, lessons and longitudinal teaching sequences were developed together with suggestions for helpful contexts and didactical models. Over the years, RME ideas were laid down in many studies, covering both general ideas on...

In this paper, the contents of Korean elementary school math textbooks before and after the revision were analyzed in order to present the trend of teaching method of ‘division of fractions’ in South Korea. Fraction division can be easily solved by using 'invert and multiplying' algorithm, It is easy for students to perform calculation mechanically without understanding. But in fact, it is...

In this article, we examine and compare how the procedures for solving one-variable linear equations and inequalities are presented in the narrative of Brazilian, Portuguese and Spanish textbooks. We analyze the main resources used, the relationships between the procedures of solving equations and inequalities, and the presence of reasoning-and-proving in the exposition of content. Results...

It is widely recognized that textbooks play an important role in teaching and learning of mathematics. Therefore, the way in which textbooks address gender equity is expected to have a significant influence on learning outcomes. However, when gender stereotyping is often investigated by textbook researchers, gender equity is rarely a concern when selecting and organizing teaching contents...

Interactions between teachers and textbooks are an active process and have an impact on mathematical lessons. International studies show that historical snippets are one way to including the history of mathematics in textbooks. Teachers must handle these tasks, but in which way they use these historical snippets? The aim of this explorative survey is to identify teachers’ language about tasks...

Report on the main ideas, the design, the practical and theoretical components and the realisations of the workshop ‘Writing Maths Textbooks’ which the author developed on behalf of the GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit) for the Republic of Yemen to teach future textbook writers how to write Maths Textbooks. Because of acts of war the workshop was delivered in 2016...

Results from earlier research found that textbook use by teachers of mathematics was largely tacit and not deliberate, making for un-intimate teacher-textbook relationships, and therefore low levels of teacher capacity for pedagogic design. The change from textbooks as primary curricular resources for teaching to daily scripted lesson plans begs a question about the kinds of relationships...

Present setcentric and pre-setcentric math are challenged by

post-setcentric math seeing math, not as a goal, but as a means to develop

the mastery of Many children bring to school.

Asked “How old next time?”, a 3year old says “Four” showing 4 fingers; but

protests if held together 2 by 2: “That is not four, that is two 2s”, thus

describing what exists, and with units: the total is bundles of...

This paper seeks to explore the value given to technology in the Chilean school mathematics textbooks.

This article presents a deeper theoretical understanding from the concept of "reading geometrically", proposed by Dietiker and Brakoniecki (2014), which is characterized as a reader’s negotiation of meaning with what is, what it is not, and may be misleading in a given diagram. They propose that from the reading geometrically is a new drawing of the diagram in the reader's mind, taking into...

More teachers from Shanghai and other provinces are taking self-learning seriously. It is all a question of the textbook’s readability. “Inverted classroom” represent major shift in this process, which require students to read the textbook by themselves. However, there are growing doubts about whether textbooks are prepared for such a big shift. Without teacher guidance, can students learn...
