Vocabulary represents one of the fundamental components influencing the development of linguistic activities and strategies, communicative competence, and thereby the overall acquisition of the target foreign language. As Laufer and Sim (1985) state, insufficient vocabulary knowledge is the biggest obstacle in understanding a foreign language,…

Textbooks are among the most important means of education in terms of instilling leadership skills in students. The characters presented as models in the textbooks play an important part in building up such leadership skills with the help of quotes from such characters, texts written with reference to them, and the activities developed…

The study describes how the common representations are coordinated. I analyzed a popular geometry textbook using semiotics and a pragmatic approach to capture the variety of representations into categories and to use descriptive statistics to narrow the focus to the most common representations and coordinations. The major findings are: (1)…

Textbooks play an important role in teachers' instructional decisions (Jones & Tarr, 2007), which consequently affects students' learning. This paper reports on a comparison of the elementary mathematics textbooks used in Iran and the United States, the Go-Math textbook. I analyzed topic sequences, frequency of the tasks, and cognitive demands…

The most important source of knowledge in primary school teaching is the textbook. This research aimed to determine the differences in graphic illustrations in the contents of natural sciences in a regular textbook and a textbook for children with special educational needs in the Republic of Serbia. As the number of subjects that deal with the…

"Geometry--Do" is a textbook about plane geometry. It will be divided into two volumes, "Geometry without Multiplication: White through Red Belt," and "Geometry with Multiplication: Blue through Black Belt. "The white- and yellow-belt chapters are neutral geometry; the remainder of "Volume One" and all of…

The purpose of this study is to examine how proportional reasoning is introduced and developed in two widely used U.S. and Korean mathematics textbooks for grades 6-7. Seven research-based frameworks that identify student learning opportunities for understanding of proportional reasoning were used to analyze the textbooks. The results showed that…

Learning logs collected by digital educational systems, increasingly deployed in educational settings, include clickstream logs recorded through page transitions in teaching materials and digital marker logs recorded by drawing a marker. A challenge with these learning logs is their low temporal and spatial resolutions. This paper proposes a…

Mathematics textbooks for upper primary classes in the English Subsystem of Education in Cameroon were examined to determine the quality of mathematics in them and possible teacher knowledge fostered. The quality of mathematics in these textbooks is classified as medium and the dominant teacher knowledge fostered is common content knowledge. This…

This study aims to examine the 5th- and 6th-grade mathematics textbooks approved by the Turkish Ministry of National Education for the 2021-2022 academic year in terms of the opportunities to learn provided in the sublearning domain of "Area Measurement." A document analysis was performed as a part of this study. Consistent with the aim…

This study explores opportunities to learn definite integrals in three widely used textbooks in the U.S. Definitions, worked examples, and exercise problems were coded using research-based cognitive resources in definite integrals. The results show that limited opportunities for students to explore multiplicative relationship between two…

Multi-angle question answering models have recently been proposed that promise to perform related tasks like question generation. However, performance on related tasks has not been thoroughly studied. We investigate a leading model called Macaw on the task of multiple choice question generation and evaluate its performance on three angles that…

This study reviews how slope is developed in expository materials across a seven-textbook series. Slope development is analyzed using a framework of five slope components to describe which components are used and connected, and by investigating accompanying levels of covariational reasoning. Findings suggest that the series describes slope from…

Over the past decade there has been a lot of discussion about the rising cost of textbooks in higher education, which has resulted in an increased interest in electronic textbooks and digital coursework. When classes moved to a virtual environment in 2020, due to the COVID-19 global pandemic, many campuses needed to quickly provide students with…

Fractions are among the most problematic concepts that children encounter in their primary school years because of the many different conceptions of fractions. Textbook analyses have tried to provide insights into how fractions are introduced, focusing on the different concepts and representations of fractions. In this paper, we contribute to…
