Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

Reading is regarded as one of the basic learning processes that provides multiple skills and abilities for daily life. The study reported on here arose from evidence of reading comprehension difficulties of middle school students in Colombia, and from reflection on the didactic strategies used for the promotion and teaching of reading. The purpose…

Wave optics is a mandatory part of Croatian secondary school physics curriculum for students in the final year of secondary school (age 18-19). Many physics education research studies have shown that it is a difficult physics topic for both university and secondary school students. An inquiry-based teaching sequence on wave optics, designed for…

Analyzing heterogeneous treatment effects (HTE) plays a crucial role in understanding the impacts of educational interventions. A standard practice for HTE analysis is to examine interactions between treatment status and pre-intervention participant characteristics, such as pretest scores, to identify how different groups respond to treatment.…

Growth mindset has received more focus in schools in the past fifteen years as a possible way to improve various educational outcomes. There are important possible benefits if students believe in the malleability of intelligence and the potential to improve in ability and various human qualities. Students with growth mindsets set self-improvement…

First-generation college students (FGCS) experience high rates of attrition compared to continuing generation college students. FGCS frequently identify with several other historically marginalized identities on college campuses. The development of a sense of belonging on-campus is one of the main drivers of retention. The current study examines…

In an era of major advances in the digital world, artificial intelligence has been a part of programs, tools, applications, and platforms. It has also been integrated into fields of education including language teaching and learning. To this end, ChatGPT, one of the most recent AI-driven systems, has been proposed to support language learners'…

Black students in today's classrooms face major challenges unknown to white teachers. In this article, the authors share instructional practices, mindsets, and reflective questions that teachers can implement, practice, and respond to in order to support Black students to feel safe and welcome in their mathematics classrooms. In doing so, the…

The present study was to explore whether dynamic visualizations enriched with visuospatial cues can optimize learners' cognitive processing of mechanical systems. The animated conditions and cueing patterns were the independent variables with an attempt to investigate their impacts on retention and transfer tests. Either dynamic or static…

This study examined the effects of adjusting the difficulty level of instructional materials on the on-task time and comprehension of four students with emotional and behavioral disorders. All participants previously exhibited low rates of on-task behavior during reading assignments. Students were presented with reading materials at their…

We report on the study of student difficulties regarding a heat engine in the context of a Stirling cycle by the method of measurement. An in-class test about a Stirling engine with a regenerator was taken by three classes, and the students were asked to perform one of the most basic activities--calculate the efficiency of the heat engine. Our…

The present study aims to compare the geometry standards in U.S. Common Core State Standards of Mathematics (CCSSM) and Chinese Compulsory Education Mathematics Curriculum Standards (CMCS) through the lens of van Hiele levels. The study considered a standard unit as one or multiple learning expectation(s) and placed each learning expectation into…

The Hindi consonant inventory, which includes the cross-linguistically rare retroflex place of articulation and four-way laryngeal contrasts, is known to pose difficulties for native English speakers. Hindi language textbooks address this challenge, in part, by providing various articulatory and acoustic descriptions of Hindi consonants, typically…

This study analysed the designs of algebraic problems in elementary mathematics textbooks used in Finland, Indonesia, Malaysia, Singapore, and Taiwan. This study employed a content-analysis method that focused on four dimensions: representational forms, cognitive demand levels (CDLs), contextual features, and types of responses. The result of the…

The efforts shown in recent years related to the reform movements in science education have focused on the assertion that informed nature of science understandings (NOS, hereafter) should be developed. In line with this idea, NOS has become the central component of numerous science curricula. In the study, therefore, it was aimed to determine…
