The aim of this personal reflection is to revisit the major concepts that have informed my academic research in the area of applied linguistics and second language development, and show how my overall pedagogical approach has evolved, thanks to the contribution of Vygotsky's sociocultural theory (SCT). The main focus of this paper is on the…

This study investigates the effects of four online vocabulary tasks on second language (L2) vocabulary acquisition among learners of different proficiency levels. While tasks are widely used to support L2 vocabulary learning, the efficacy of a task depends on the interplay between task and learner factors. Thus, choosing an appropriate task…

This article explores how seven Swedish digital teaching platforms in mathematics make use of the affordances provided by various modalities and dynamic functions. A model based on social semiotics is used to analyse how dynamic functions are used, whether or not the language is technically oriented, if relational or operational processes are…

It is well known that students benefit from opportunities to interpret and create different representations (e.g., diagrams, graphs, tables, symbols) of mathematical ideas. Employing Marton's Variation theory as a lens, I argue for an expansion of the use of multiple representations in task design for graphs: Incorporate two different forms of the…

In vocational education, the learning content is often considered as concrete and specific, and the vocational learning involves physical work and interactions between participants and artefacts. Furthermore, one teacher has the overall responsibility for several students during classes in the vocational workshop at school, which means that the…

In this paper duality between real world phenomenon and mathematics will be discussed. This duality exists for many years which considerably remarked in the history of mathematics curriculum. One of the good potential for filling the gap between real world phenomenon and mathematical ideas would be modelling tasks which require performing the…

Peer collaboration benefits second language (L2) learning and is a cornerstone of effective classroom instruction. It is, therefore, essential for teachers to consider how tasks work to promote peer collaboration and thus maximize learning. These considerations concern the task type, a task's inherent characteristics, and possible ways of task…

This paper reports on ongoing research aimed at characterizing a signature pedagogy (Shulman, 2005) of technology-enhanced task-based language teaching (TETBLT). To achieve this goal, we initially identified 15 pedagogical principles and practices distinctive of TETBLT. This initial set of principles and practices were motivated by second language…

This article argues for the possibility and importance of infusing frame semantic insights into task-based lesson planning. "Frame semantics," a cognitive linguistic theory that takes a usage-based view of meaning, ties in with task-based language teaching (TBLT), which emphasizes second or foreign language learning through…

The past 40 years have witnessed significant developments in ELT research, reflecting the changes in learners' language needs and the extensive development of various language learning/teaching methods in different times and places. The aim of this study is to provide a systematic and comprehensive account of changing ELT methods (oral-structural…

The attribution of learning success or failure is crucial for students' learning and motivation. Effective attribution of their learning success or failure in the context of a small private online course (SPOC) could generate students' motivation toward learning success while an incorrect attribution would lead to a sense of helplessness. Based on…

Young children tend to rely on reactive cognitive control (e.g. strongly slow down after an error), even when task accuracy would benefit from proactive cognitive control (taking a slower task approach up front). We investigated if giving young primary school children opportunities to repeatedly experience tasks where success rates depend on…

This study is a case study within a three-year-long design research study. The purposes of this study are twofold. The first purpose includes investigating whether there is a significant difference in seventh-grade students' proportional reasoning skills before and after a teaching experiment conducted in line with the perspectives of Hypothetical…

A balanced interrelation between theory and practice is still often missing out in many (language) teacher education programs (Esteve, 2018; Lantolf & Esteve, 2019). Hence the need to critically analyze teacher educators' professional practice and rethink it. This paper presents a deep reflection upon the difficulties and the possibilities of…

Measurement is a critical component of mathematics education, but research on the learning and teaching of measurement is limited. We previously introduced, refined, and validated a developmental progression -- the cognitive core of a learning trajectory -- for length measurement in the early years. A complete learning trajectory includes…
