It is imperative to collect validity evidence prior to interpreting and using test scores. During the process of collecting validity evidence, test developers should consider whether test scores are contaminated by sources of extraneous information. This is referred to as construct irrelevant variance, or the "degree to which test scores are…

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…

Why do people shift their strategies for solving problems? Past work has focused on the roles of contextual and individual factors in explaining whether people adopt new strategies when they are exposed to them. In this study, we examined a factor not considered in prior work: people's evaluations of the strategies themselves. We presented…

This study aims to advance our understanding of the nature and source(s) of individual differences in pragmatic language behavior over the adult lifespan. Across four story continuation experiments, we probed adults' (N = 496 participants, ages 18-82) choice of referential forms (i.e., names vs. pronouns to refer to the main character). Our…

The anthropological theory of didactics (ATD) provides a lens to view mathematics education by placing mathematical practices within socio-cultural and historical contexts. The significance of institutions, in what regards with educational establishments, societal structures, cultural norms, and historical contexts, influences the perception and…

This study aims to analyze the research outputs of immersive technology in the field of education for the past two decades. To this end, we retrieved 2665 articles that contained 75674 valid references from the Scopus database for the period between 2001-2021. Several structural and temporal metrics were used to find out the emerging topics…

Sign language learners with a spoken language background face the challenge of acquiring a second language in a different modality. In the course of this endeavor, one of the modality-specific phenomena they encounter is the use of classifier predicates, also known as depicting signs. Classifier predicates contain a meaningful hand configuration…

Language acquisition and Language Maintenance (LM) both depend on ample opportunity and motivation. Currently, many national language societies are undergoing Language Shift (LS) to English, impacting their acquisition as first (L1) and possibly even more as second (L2) language. This study interviewed 44 adolescents, including 24 L1 and 20 L2…

Virtual reality learning environment (VRLE), which allow students to transcend time and space and provide them with a sense of immersion, is becoming more common in education. Although many studies have explored the effects of VRLE on learners' learning outcomes as well as learning experiences, the results of these studies indicate that the…

Automatic generation of math word problems (MWPs) is a challenging task in Natural Language Processing (NLP), particularly connecting it to real-life problems because it can benefit students in developing a higher level of mathematical thinking. However, most of the MWPs are presented within a scholastic setting in a decontextualized way. This…

In Ireland, Initial Teacher Education [ITE] standards require all teachers to possess an adequate level of numeracy themselves in order to teach for numeracy learning across the school curriculum. This paper reports on a study that investigated 204 pre-service post-primary teachers' numeracy capabilities. Analysis of questionnaire data from…

Teachers have difficulty integrating proof in their mathematics instruction due to both narrow beliefs about proofs and limited understanding of proofs. Indirect proofs seem to be a particular cause for concern. In this exploratory study, we contribute to the research area by reporting on an empirical study of Norwegian pre-service teachers'…

The biology material on the excretory system has a high level of learning difficulty, including the complexity of the material and the high level of abstraction, which can affect students' learning process and outcomes. Therefore, it is necessary to analyze the internal and external sources causing learning difficulties by conducting research that…

The aim of the study was to examine how students generate problems about the concept of series, and how they evaluate and solve these problems. The difficulties experienced by the students while posing problems and their perceptions of the posing-evaluating-solving approach were also explored. In the first stage, 46 second-year university students…

This study explored the communication strategies of college students majoring in one of five modern foreign languages (i.e., English, French, German, Japanese, and Spanish) and their relation to communication confidence. It also explored the association between their strategy use and the difficulty regarding the speaking components, and students'…
