We describe the mathematical content knowledge a teacher needs in order to achieve a basic level of competence in mathematics teaching. We also explain why content knowledge is essential for this purpose, how Textbook School Mathematics (TSM) stands in the way of providing teachers with this knowledge, and the relationship of this concept of…

This study was conducted to see to what extent pragmatics is incorporated into a newly published EFL textbook series for Vietnamese upper-secondary school students under the National Foreign Language Project 2020 (NFLP 2020). The results show that there is a paucity of explicit information on pragmatics in this series. In addition, the…

This article presents Oregon State University's experience launching an innovative Open Textbook initiative in spring 2014. The partners, Open Oregon State and the Oregon State University Libraries and Press, aimed to reduce the cost of course materials for students while ensuring the content created was peer-reviewed and employed multimedia…

This paper investigates how three widely used calculus textbooks in the U.S. realize the derivative as a point-specific object and as a function using Sfard's communicational approach. For this purpose, the study analyzed word-use and visual mediators for the "limit process" through which the derivative at a point was objectified, and…

This study explores the assessment of the alignment of mathematics instructional materials with the Common Core State Standards for Mathematics (CCSSM). First, focus, rigor, and coherence, identified in TIMSS studies and also established for CCSSM, were chosen as criteria of alignment. Then, the CCSSM Graph (Zimba, 2012) was used as a yardstick to…

The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

This research was conducted to evaluate the efforts made by Turkish teachers on developing written expression in their classrooms by considering the basic principles of the process-based writing approach and to determine whether the students' written expressions meet the basic principles of the process-based writing approach. In this respect, the…

Lexical meaning, as an important and essential aspect of the word, has long attracted the attention of scholars, who, in trying to know its nature, have sometimes mystified it by seeing it as an inexplicable thing and sometimes simplified it, equating it with the function of the word, with the concept, even with the "reali" itself that…

One of the central paradoxes of textbook authorship in Indigenous languages is that some of those for whom the textbooks are intended find it challenging to read them. Here, through examining cases of Quechua across the Andes in Peru and in Ecuador, we consider the role of orthography in this paradox. Textbook authors must decide on an alphabet…

Increasingly, studies are taking account of multimodality when analyzing language textbooks. Due to the diversity of multimodal frameworks used in analyses, and the interdisciplinary nature of language textbook studies, conceptual differences arise that are important to discuss -- which is the purpose of this paper. Specifically, I argue that…

Nowadays, unhealthy dietary habits, insufficient food knowledge, and lack of manual skills are typical issues among primary and secondary school students in China. To help students build up a strong constitution and life wisdom, Weifang Hansheng School of Shandong developed a food education course. This paper expounds on the course framework,…

Testing-effect literature has shown the benefits of retrieval practice to enhance retention and attenuate forgetting. However, research in memory reconsolidation has demonstrated that a memory trace can be rendered labile by retrieval and requires restabilisation to persist. This study investigated the effects of the initial test interval and…

A case study is used to achieve two research objectives: To understand students' attitudes, behavior toward, and satisfaction with videobooks vs. traditional textbooks; and to identify factors that drive student satisfaction and positive attitudes toward videobooks. Analysis of student experiences across multiple sections of an introductory…

For teachers to integrate ethnomathematics approaches, it is essential to understand their views related to the implementation challenges of such approaches. In schools, teachers held previous views and experiences that influenced their integration of ethnomathematics approaches. This study investigates school-related factors that impede the…

This research aimed to reveal teachers' opinions about how the grammar-teaching process is related to the acquisitions in the curriculum, activities, and acquisitions presented in the textbooks teaching in mother tongue, the study reviewed different textbooks from four publishers, Cem, Sonuç, Koza, and Ministry of National Education (MEB)…
