The purpose of this article is to conduct a mathematical and phenomenological comparison of three concepts: (1) the finite limit of a function at a point, (2) the finite limit of a sequence, and (3) the infinite limit of a sequence. Additionally, we aim to analyse the presence of these concepts in Spanish textbooks. The methodology employed is…

This article reports on the effect of textbook analysis as a tool of teacher professional development on nature of science (NOS) understanding of 10 science teachers in South Africa. The teacher professional development program (TPDP) was based on an explicit reflective methodology of textbook analysis and conducted online due to the Covid-induced…

Probability is a difficult concept, which is not always taught accurately. This study aims to clarify how experimental and theoretical probabilities are taught in Japanese 7th and 8th grades through a textbook analysis. We analyzed seven, government approved Japanese 7th and 8th grade textbooks each. Focusing on the definition and explanation of…

Textbooks are one of the learning mediums. The activities in mathematics textbooks and qualities of these activities are of paramount importance. Problem-posing is one of the activities in these textbooks. Many researchers emphasize that examination of textbooks is important in explaining student success. The purpose of this study was to examine…

The contribution gives insights into a comparative linguistic textbook analysis of two Austrian Catholic Religious Education (RE) textbooks for colleges for higher vocational schools ('BHS') and vocational schools for apprentices ('VocEd'). Gender constructions are still a desideratum in RE textbook research in Austria. Previous gender-oriented…

In this study, it is aimed to examine the text-based questions in the secondary school Turkish textbooks according to the revised Bloom's Taxonomy and to evaluate these questions according to the cognitive domain steps. In the research, the text-based questions in the Turkish textbooks approved by the Ministry of National Education were examined…

"Representational transformation diagrams" are used to compare and contrast standard textbook presentations of vector line integrals in undergraduate courses in both mathematics and physics. These presentations are taken as the lower anchor in a learning trajectory. Two principal approaches in the lower division are identified, roughly…

Integrating the nature of science (NOS) into textbooks is one of the challenges in science curricula. This case study assessed the issue based on a sample of high school biology textbooks in Mainland China. We quantitatively compared changes in the extent, quality, and distribution of NOS representations between 2004 and 2019 editions. Three main…

During the sixteenth century, a relevant number of books related to practical arithmetic were published in Spain. This paper presents a comparative study that aims to identify the object and target of five old mathematics books and the main contents of these books. In order to do so, all the contents and all the examples found in five arithmetic…

The topic of the Federal Reserve's (the Fed's) implementation of monetary policy has a significant presence in economics textbooks. Unfortunately, as the Fed purposefully shifted the way it implements monetary policy to an environment with ample reserves in the banking system, many textbooks have not kept up. The authors walk through the key…

Data analysis is one of the most popular fields of mathematics and includes statistics and probability. These two mathematical domains are some of the most well-known, influencing everyday life and the various sciences. Their teaching lays the foundation for primary education and culminates in secondary education. Probability and statistics are…

In response to the 2001 National curriculum review in China, which explicitly promotes scientific inquiry in science-related subjects, many editions of new textbooks were published. Among them, this study explored the quality of scientific inquiry in the most popular science textbooks. There are nine sets of high school science textbooks published…

School history textbooks provide an important source of information for learners of history. Textbook narratives of a nation's past often present a limited frame of reference, which impedes the aim of teaching history from multiple perspectives. This article examines the representation of the Dutch Revolt in two Dutch and two Flemish history…

The current study explores the relationship between social contagion and vocal fillers. An experiment was conducted in which 100 students presented speeches. Prior to presenting their speech, half of the students were exposed to a speech with excessive vocal fillers and half were exposed to a speech with no vocal fillers. Students who heard a…

Based on the "analytical framework of nature of science" (NOS) in junior school science textbooks, a content analysis method was adopted to analyze the NOS in junior middle school physical textbooks (grade 8) of five editions authorized by the Ministry of Education of China, and the features of NOS were analyzed and compared. It was…
