The opinions of mathematics teachers about using mathematical modeling (MM) in daily life problems and their use of MM in solving a daily life problem were examined within the scope of the graduate-level MM course in this study. The research was designed as a case study. Participants are five mathematics teachers selected by the purposive sampling…

An evaluation of the national curriculum by practitioners suggests that learning materials across school levels still overlap, are irrelevant to student development phases and competencies required, too challenging for students to learn, too broad in terms of topics, and lacking in depth. This evaluation encourages the needs for special studies…

This study examined the validity of the Korean version of the Child Behavior Checklist (K-CBCL) with 180 children with autism spectrum disorder (ASD) in South Korea. Rasch analysis was applied to examine item fit, item difficulty, suitability of the response scale, and person and item separation indices of the K-CBCL. The results indicated that,…

In this study, I sought to investigate whether visuospatial working memory (VWM) explains individual differences in reading fluency growth. One hundred and thirty Japanese junior and senior high school students were administered the Mr. Peanut and reversed Corsi tasks, respectively as measures of VWM, followed by three waves of reading fluency…

Control of variables strategy (CVS) is a core scientific reasoning skill related to domain-general experimentation for evaluating an experimental system and deducing valid conclusions. This study aims to develop, validate, and explore latent factors predicting item difficulty in the test, measuring CVS in physics for high school students. The…

Purpose: Children with developmental language disorder (DLD) demonstrate general spelling difficulties. This study investigated accuracy on and sensitivity to silent letters in spelling in children with and without DLD. Investigating silent-letter production provides a window into orthographic and morphological knowledge and enhances understanding…

Given the important role that teachers play in supporting student mental health, it is critical teachers feel confident in their ability to fill such roles. To inform strategies intended to improve teacher confidence in supporting student mental health, a psychometrically sound tool assessing teacher school mental health self-efficacy is needed.…

Preparing for the future during ongoing activities is an essential skill. Yet it is currently unclear to what extent we can prepare for the future in parallel with another task. In two experiments, we investigated how characteristics of a present task influenced whether and when participants prepared for the future, as well as its usefulness. We…

Purpose: Complex features of science texts present idiosyncratic challenges for middle grade readers, especially in a post-Common Core educational world where students' learning is dependent on understanding informational text. The primary aim of this study was to explore how middle school readers process science texts and whether such…

In Asia, in order to keep up with internationalization, the English-Medium Instruction (EMI) course has become a phenomenon in higher education. In turn, EMI literature has increasingly focused on the role of instructor's pedagogy in reducing students' negative response to EMI courses. Additionally, we further explore, from the students'…

Universities face the challenge of constantly improving the quality of higher education and changing the learning behaviour of students, from passive reactive learning to active self-regulated learning. Learner-centred, constructively designed learning tasks offer a great opportunity here. This paper investigates to what extent the learning…

Analyzing the writing skill of English language learners emerges from understanding the accuracy, fluency, and complexity of texts and classifying written errors according to syntax, morphology, and lexicon. In this quantitative descriptive-analysis study, the participants included thirty one Spanish-speaking, Mexican English language learners who…

A few case studies have suggested students' struggles with the "temporal order" of epsilon and delta in the formal limit definition. This study problematizes this hypothesis by exploring students' claims in different contexts and uncovering productive resources from students to make sense of the critical relationship between epsilon and…

This study examined the impacts of 2 different graphic organizers (filled-in graphic organizers and interactive graphic organizers) on middle school students' learning processes, outcomes, experiences, and preferences. In Experiment 1, 60 students were assigned to read a short expository passage in 1 of 3 conditions: text-only, filled-in graphic…

Mobile social media are increasingly being used in education. They provide an effective way to address the imbalance between teaching supply and demand for older adults. However, few studies have investigated which factors contribute to older adults' intention to use mobile social media for learning. This study uses a sequential explanatory mixed…
