This article is a conceptual and methodological exploration of a new construct, task interactional difficulty, and of a possible approach to assessing task demands in general. After arguing for the use of 'task difficulty' instead of 'task complexity', the notion of task interactional difficulty is analyzed, first by reviewing previous SLA…

This article discusses why pedagogical discourse analysis (PDA) can be seen as the departure point to teach through discourse and how language teachers can efficaciously use it in order to bring discourse analysis into the language classroom. To make PDA feasible in language teaching, it requires to be coordinated with actual discourse-based…

Tackling mathematics tasks often involves reading and interpreting different semiotic resources such as natural language (words), mathematical notation, and images. This study aims to enhance knowledge of how meaning relations, in the form of "cohesive ties" between and within different semiotic resources, are related to how difficult it…

This paper sets out to explore English language materials development since the emergence of communicative language learning (CLT). Many pedagogical approaches have been innovated to reach the goal of CLT. It will discuss the most common approach of English language materials development used nowadays. This paper specifically introduces a new…

K-12 students are expected to acquire competence in data display as part of developing statistical literacy. To support research, assessment design, and instruction, we developed a hypothesized learning progression (LP) using existing empirical literature in the fields of mathematics and statistics education. The data display LP posits a…

In this study, we designed and applied physical computing lessons for elementary 6th-grade students based on the software education guidelines in the Korean 2015 Revised National Curriculum (Ministry of Education, 2015a). The participants of this study were ten 6th-grade students of an elementary school in Gyeonggi-do province in Korea. The…

This is the third in a series of papers focusing reasoning-and-proving. Participants were in-service teachers enrolled in a continuing university education programme in teaching mathematics for grades 5-10. Data were collected from a course assignment in 2018 and 2019, where the in-service teachers reported about their students' work with a…

Success in higher education is highly dependent on students' ability to efficiently read and comprehend large amounts of text in the speaker's first/native language (L1) and also in a Foreign Language (FL). Good text comprehension requires readers to implement a variety of metacognitive processes in order to self-regulate understanding. However,…

In this article, we present a set of design principles to guide the development of instructional materials aimed to support preservice secondary mathematics teachers (PSMTs) examining student practices in technology-mediated environments. To develop design principles, we drew on the literature related to technological pedagogical content knowledge…

This study examines L2 fluency in speaking interactions based on the number and type of utterances. The participants were 25 Korean eighth-grade learners of English as a foreign language. They performed five communicative tasks in groups, and their speaking interactions were audio-recorded and analyzed to measure the frequencies of sentence-level…

The main goal of this study was to analyze the development of historical thinking abilities in two groups of fourth graders in Colombian schools. The study consisted of the design, implementation, and evaluation of a three-month pedagogical intervention. After an initial assessment, nine learning activities were implemented. An Intervention Group…

This book examines the use of tasks in second language instruction in a variety of international contexts, and addresses the need for a better understanding of how tasks are used in teaching and program-level decision-making. The chapters consider the key issues, examples, benefits and challenges that teachers, program designers and researchers…

Purpose: Environmental social work (ESW) is an approach and a perspective in social work focusing on ecological and environmental sustainability and justice within the context of sustainable development (SD). This study aims to analyse students' reflective tasks on challenges for ESW education and practice from a critical theory perspective. The…

Patterning tasks engage students in a core aspect of algebraic thinking-generalization (Kaput 2008). The National Council of Teachers of Mathematics (NCTM) Algebra Standard states that students in grades 9-12 should "generalize patterns using explicitly defined and recursively defined functions" (NCTM 2000, p. 296). Although educators…

One of the central challenges educators face today, especially in higher education, is the gap between warranted (domain-specific) knowledge and the prior beliefs students hold about certain concepts and phenomena (preconceptions). In the Internet age, students often self-directedly acquire knowledge from an increasingly large number of…
