Background: Despite the numerous positive effects of augmented reality (AR) on learning, previous research has shown ambiguous results regarding the cognitive demand on the learner arising from, for example, the overlay of virtual elements or novel interaction techniques. At the same time, the number of evidence-based guidelines on designing AR is…

There is extensive empirical research on principles of effective teacher professional development (PD). However, teachers' expectations of PD and how well these align with scientific recommendations are only rarely addressed. N = 125 teachers were presented with video vignettes on two evidence-based interventions of varying complexity for which…

Teaching practices that are aligned with how students learn improve educational outcomes for all students. Empirical evidence gained over recent decades has provided important new insights about the learning process common to students across learning contexts. These processes explain why some teaching practices are more effective than others. In…

Mid-20th-century scholars argued that second language (L2) instruction should be rooted in a comparison of the structural characteristics of the first language (L1) and L2. Their enthusiasm for a "scientific" approach to errors reflected the view, based on the contrastive analysis hypothesis (CAH), that learners' difficulties could be…
