From an APOS (Action-Process-Object-Schema) theory perspective, learning mathematics involves construction of knowledge through mental mechanisms, which evolves between different mental structures or stages. The focus of this study is to explore how transition occurs from an Action to a Process conception, in the context of a task related to the…

If maximal exposure were the key to success in language learning, then adult learners at the university level would be doomed to fail. Not only are they presumably too old to learn additional languages effectively, but target language (TL) input appears to be insufficient, especially when other languages are allowed in class. Nevertheless,…

We report the results of a study on informal covariate statistical reasoning conducted with 22 students (aged 16 and 18 years). We designed and implemented a task in a digital technology environment to introduce the line of best fit. The task design having elements that foresee misconceptions reported in the literature, and by focusing on four…

The aim of this research is to propose indicators of epistemic and mediational suitability to assess tasks designed in a mobile learning context, using theoretical and methodological elements of the onto-semiotic approach (OSA) and the SAMR model (substitution, augmentation, modification, and redefinition). With these indicators, 110 tasks…

This study was conducted from a perspective that adopts a broad vision of mathematical talent, defined as the potential that a subject manifests when confronting certain types of tasks, in a successful way, that generate creative mathematical activity. To analyse this, our study proposes a Praxeological Model of Mathematical Talent based on the…

Controversy about whether English for General Purposes (EGP) or English for Specific Purposes (ESP) should be taught at university courses has attracted the attention of language teachers and researchers in Mexican higher education during the last decade. However, moving towards ESP remains a complex task since EFL instructors and authorities are…

A mathematical client-driven task known as Model-Eliciting Activities was implemented with students of different levels of achievement (i.e., low, average, and high) at the high-school level. The study strived to prove that Model-Eliciting Activities can be solved by students at any achievement level and be used as an assessment tool. Students…

In this paper I introduce a methodological approach that can be useful for investigating relationships between mathematics tasks, mathematical classroom cultures and mathematics learning. This proposal responds to a need, identified in the literature, for "further research which uses alternative methods to understand student perspectives more…

The aim of this study was to examine the characteristics of teacher education that were more likely, or less likely, to influence teachers' beliefs. The participants were five university English teachers in Mexico, and the study adopted a qualitative "life history" approach in order to elicit a wide range of experiences from each…

Despite a growing amount of research on collaborative dialogue during task performance, little attention has been given to the occurrence of collaborative dialogue across task modality and its impact on language development. To expand our current understanding of task modality effects on learning opportunities, we examined the process of engaging…

I examine whether teaching formulaic language raises English as a foreign language learners' awareness of pragmatic resources when expressing requests. To carry out this research I adopt a qualitative self-reflective approach which encourages students to use formulaic language when making requests. By responding to discourse completion tasks,…

Due to the growing number of plurilingual learners in the world today (Hammarberg, 2010), the present multiple case study examines four plurilingual participants' beliefs toward first language (L1) and second language (L2) mediation in the acquisition of French as a third language (L3). During a 16-week classroom-based study in a French university…

The importance of teachers in the success of Task-Based Language Teaching (TBLT) is unquestionable. However, designing a teacher course on TBLT raises many questions concerning "what" and "how" it can be implemented. Can teachers' professional development be promoted through Task-Based Instruction (TBI)? This paper explores…
