The concept of variability is central to statistics. In this research report, we review mathematics education research on variability and, based on that review and on feedback from an expert panel, propose a learning progression (LP) for variability. The structure of the proposed LP consists of 5 levels of sophistication in understanding…

The purpose of this study is to identify the effectiveness of the task-based approach to teaching business vocabulary to master's degree students while studying business English. The discipline of business English aims to develop students' ability to analyse and solve problems of the business environment, improve their foreign language competence…

Purpose: This clinical focus article will highlight the importance and role of morphological awareness (MA) across orthographies, in particular, the role it plays in reading development, specifically with bilingual populations. MA supports reading acquisition and development beyond other predictors of reading, such as phonological awareness,…

Proficient bilinguals use two languages actively, but the contexts in which they do so may differ dramatically. The present study asked what consequences the contexts of language use hold for the way in which cognitive resources modulate language abilities. Three groups of speakers were compared, all of whom were highly proficient Spanish-English…

For higher education graduates to be effective in the workplace, they require strong technical skills and the capability to operate across diverse knowledge landscapes to solve real world problems. At an Australian university, an interdisciplinary, short-term study tour programme was utilised to enhance students' inexplicit employability skills…

Adopting a broader dialogical conceptual lens on interactive listening, this study examines advanced adult learners' language use and thought processes during a problem-solving task. Twenty English as a second language (L2) students from a Scottish university participated in the study. They worked in pairs on the task before taking part in…

The present study investigated the longitudinal effects of early exposure to L2-English on L1-Turkish language competence, narrative skills and executive functioning. We asked whether early immersion-like exposure to L2, starting around 3 years of age, would have reflections on L1 competence, L1 narrative skills and gains in cognitive flexibility.…

The present study investigated the interface between explicit instruction and computer-assisted language learning (CALL) in an effort to reduce plural marking errors among Japanese EFL learners. The instruction involved raising contrastive awareness of cross-linguistic and conceptual features, and was delivered via an online medium. A total of 180…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…

Bilinguals often outperform monolinguals on executive function tasks, including tasks that tap cognitive flexibility, conflict monitoring, and task-switching abilities. Some have suggested that bilinguals also have greater working memory capacity than comparable monolinguals, but evidence for this suggestion is mixed. We therefore conducted a…

Background: Pupillometry has been studied as a physiological marker for quantifying cognitive load since the early 1960s. It has been established that small changes in pupillary size can provide an index of the cognitive load of an individual as he/she performs a mental task. The utility of pupillometry as a measure of expertise is less well…

Visual presentations may assist students with autism spectrum disorder (ASD) to access instruction, and they may be more engaged when interacting with screen media in particular. Interactive whiteboards (IWBs) are large electronic screens that are used for instruction in many classrooms. An alternating treatment design was used to compare the…

Learning whether English nouns are countable or not is a source of great difficulty for many ESL/EFL learners. In the present study, a grammaticality judgement task comprised of a range of nouns representative of the different facets of the countability system in English was distributed to 82 native speakers of English (NSs) and 98 non-native…

Covariational reasoning has been the focus of many studies but only a few looked into this reasoning in the polar coordinate system. In fact, research on student's familiarity with polar coordinates and graphing in the polar coordinate system is scarce. This paper examines the challenges that students face when plotting polar curves using the…

In this article we present a didactic proposal for teaching linear algebra based on two compatible theoretical models: emergent models and mathematical modelling. This proposal begins with a problematic situation related to the creation and use of secure passwords, which leads students toward the construction of the concepts of spanning set and…
