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…

We explore the effect of students' perceived task difficulty on the mathematics self-efficacy -- performance relationship. Specifically, we expand on previous reciprocal effects studies through including students' self-efficacy for different levels of task difficulty in an empirical investigation. We examined students' self-efficacy for easy,…

The purposes of the research were to: (1) create a scientific creativity measure for high school students; (2) examine the quality of the science creativity scale of the created test; (3) establish a benchmark for scientific creativity scores for high school students; and (4) study a scientific creativity level of students in the senior high…

Assessing students on-the-fly is an important but challenging task for teachers. In initial teacher education, a call has been made to better prepare pre-service teachers for this complex task. Advances in technology allow this training to be done through authentic learning environments, such as video-based simulations. To understand the learning…

The objective of this study was to validate a bilingual Spanish-English version of the Vocabulary Size Test (VST) considering its potential use as a discriminator between learners in terms of language competence. This version was designed based on the two forms available on one of the creators' websites as well as considering practices recommended…

Introductory sociolinguistics courses at university can be challenging, especially for students at the very beginning of their tertiary studies. Difficulties may arise due to students not having any prior exposure to the discipline's content or methodologies, which is likely to be a result of these aspects not generally being taught in high…

Patterning, as a component of early mathematic knowledge, is a common activity carried out at elementary levels in which children are not equally successful. This study aimed to measure different variables affecting performance on patterning tasks in early childhood. For this purpose, the success of Pre-K (N = 33), K (N = 31) and first-grade…

This study aims to explore the impact of an augmented reality (AR) scientific inquiry tool based on a brain-computer interface (BCI) on students' scientific performance, flow experience, self-efficacy, and cognitive load of primary school students. The BCI-based AR inquiring tool provides real-time attention feedback to students' activities in an…

Many scholars compared various item discrimination indices in real or simulated data. Item discrimination indices, such as item-total correlation, item-rest correlation, and IRT item discrimination parameter, provide information about individual differences among all participants. However, there are tests that aim to select a very limited number…

The goal of the present study was to address the analytical complexity of incorporating responses and response times through applying the Jeon and De Boeck mixture item response theory model in Mplus 8.7. Using both simulated and real data, we attempt to identify subgroups of responders that are rapid guessers or engage knowledge retrieval…

Objective: We investigated how individuals deal with the limits of their own knowledge and productively cope with their dependence on experts as they engage with the socio-scientific topic of nuclear energy. We scrutinized the effects of content features of an interview text and of individuals' communicative engagement with the information read.…

The purpose of this study was to examine the use and cognitive load associated with Open Educational Resources (OERS) and Affordable Digital Textbook (ADT) among prelicensure Baccalaureate of Nursing students in an asynchronous on-line health policy course. OERS and ADT provide low student cost curriculum options for nursing faculty. The…
