Given the importance of modelling in mathematics classrooms, and despite the extensive body of research on teacher support for promoting the mathematical modelling cycle in the classroom, authors have overlooked how teacher support for argumentation can contribute to this cycle. This study is aimed at characterizing teacher support for…

Self-efficacy perceptions on second language settings have been linked to several aspects including learner performance in linguistic tasks, willingness to communicate, and language learning strategy use. These firmly place self-efficacy as a variable affecting cognitive and contextual aspects in language learning settings. However, the amount of…

The purpose of this mainly descriptive study was to investigate teachers' perceptions about how they teach writing as well as their beliefs about preparation and efficacy to teach this skill. It also examined if preparation and efficacy beliefs along with teaching experience (years teaching the language arts) predicted teachers' reported writing…

Blended learning, which combines face-to-face workshops with self-directed online learning, is becoming a good alternative in designing and deploying professional development programs. The online component adapts to teachers' time constraints, requires fewer trained professionals for its implementation, and enhances participants' opportunities to…

Mathematics classrooms in which students engage in argumentation constitute a favourable context to analyse how teachers recognize and incorporate student contingencies. Through exploratory case studies, we examined three mathematics lessons in which teachers support argumentation in contingent situations triggered by student errors. Teachers'…

Purpose: The purpose of this study was to examine the digital competence displayed by a primary school teacher who implemented an interdisciplinary cross-border lesson that was designed with the lesson study methodology and involved two countries--Brazil and Chile. Design/methodology/approach: A qualitative methodology was adopted via the case…

Teacher practice is normally assessed by observers who watch classes or videos of classes. Here, we analyse an alternative strategy that uses text transcripts and a support vector machine classifier. For each one of the 710 videos of mathematics classes from the 2005 Chilean National Teacher Assessment Programme, a single 4-minute slice was…
