This study investigated if the difficulty of instructional classroom English in primary teacher-guidebooks of English is adequately manipulated by learner-proficiency. Corpora of classroom English were compiled from 20 guidebooks from five publishers, approved following the 2015 Revised National Curriculum of Korea. Extracted materials from grades…

In order to translate and be translated, low-diffusion languages often use strategies that differ from those used by widely spoken languages and therefore create particular challenges for translators. One such strategy is indirect translation (including also relay interpreting). Since there are conflicting opinions about this practice within the…

This study examines the construct of distance -- the degree of difficulty of interacting with something -- as part of activity involving children using touchscreen digital games to learn mathematics. Ten fifth-grade children engaged in video-recorded semi-structured task-based interviews in which they used two touchscreen digital mathematics games…

Aim/Purpose: This study aims to examine the challenges faculty members face with online teaching practices in public universities in Karachi, Pakistan during the COVID-19 pandemic. Faculty members' pedagogical experiences were examined by following the approach of the technology acceptance model (TAM) framework presented by Davis in 1986 and 1989.…

Fractions are perceived as one of the most difficult areas in school mathematics to learn and teach. The most frequently mentioned factors contributing to the complexity are fractions having five interrelated constructs (part-whole, ratio, operator, quotient and measure) and teachers' pedagogical approaches to address these constructs. The present…

Developing textbooks of optimal quality is crucial for enriching the students' learning and understanding. This study examined fraction addition and subtraction problems in the U.S. and South Korean mathematics textbooks according to the types of denominators. In particular, we investigated Everyday Mathematics (EM) and South Korean mathematics…

This study reviews the difficulties that learners of English as a second or foreign language encounter in the use of English articles and puts forward some suggestions that can help advanced learners overcome their problems. It has been observed that learner performance may be deceptive and accurate article selections may be led by inappropriate…

Science and technology (S&T) plays a central role in today's knowledge- and technology-based society. The transfer of S&T from the education system to the economy should be promoted by teachers using innovative behaviour as an important aspect of providing high-quality education. Several studies have found that a mismatch exists between…

Understanding plate tectonics is pivotal to development of an integrated understanding of Geoscience topics. However, geology is frequently introduced to students in lower secondary school by describing separate processes, such as sedimentary rock formation, rather than investigating the overall driving forces for change. This study investigated…

The aim of this study was to show that some of the errors made by students when responding to mathematics assessment items can indicate progress in the development of conceptual understanding. By granting partial credit for specific incorrect responses by early secondary students, estimates of the difficulty of demonstrating full and partial…

Although trigonometry is an important section in secondary school mathematics curricula, many teachers find it challenging to teach as a result of insufficient pedagogical content knowledge (PCK). Therefore, the aim of this article was to report on how PCK on trigonometry manifests itself in teachers' practice. This exploratory case study was…

Mandarin has been added to the list of second additional languages (SAL) that South African learners can choose from. The researchers proactively conducted research pertaining to SAL (Mandarin) since it is a dynamic phenomenon in South Africa. The research question was formulated as follows: "Do factors such as 1) phonemic differences between…

This paper examines the factors accounting for students' predilection or aversion for school Geography. The paper draws on data from 116 students (aged 14-19 years) sampled from three public Senior High Schools (SHSs) in the Offinso Municipality of the Asante Region, Ghana. We employed the a posteriori inductive reduction model to derive broad and…

In this article we show how students' productive struggle on a mathematical task can lead to collective mathematical creativity. We use observable (co)actions and interactions from a video record that features three Grade 6 students in a problem-solving session to document the emergence of collective creativity leading to a solution. We discuss…

Although a number of studies have been conducted to explore how various individual difference (ID) factors such as aptitude, motivation, and anxiety contributing to L2 learners' speech performance over a period of time of L2 learning, only a few examined the effect of the three ID factors on learners' L2 speech performances based on classroom…
