Abstract The last decade has witnessed increasing interest in the study of teacher noticing mathematics education research; however, little is known about growth and how it influenced by teaching practice. Departing from expert-novice-paradigm, this paper we address research gap a cross-sectional that investigates Chinese teachers’ affected their developmental stage, measured length experience....

This paper considers the issue of 'noticing' in second language acquisition, and argues for the potential of handheld devices to: (i) support language learners in noticing and recording noticed features 'on the spot', to help them develop their second language system; (ii) help language teachers better understand the specific difficulties of individuals or those from a particular language backg...

High-similarity concept pairs that elicit many commonalities also elicit many related differences (Gentner & Markman, 1994; A. B. Markman & Gentner, 1993a, 1993b, 1996; A. B. Markman & Wisniewski, 1997). This finding has been used to support the claim that the comparison process is one of structural alignment. However, it is possible that the difference advantage results from some other propert...

We present Submatrix-wise Vector Embedding Learner (Swivel), a method for generating lowdimensional feature embeddings from a feature co-occurrence matrix. Swivel performs approximate factorization of the point-wise mutual information matrix via stochastic gradient descent. It uses a piecewise loss with special handling for unobserved co-occurrences, and thus makes use of all the information in...

Recasts are an important type of implicit negative feedback that has attracted much attention in both L1 research and SLA research. The utility of recasts in face-to-face interaction has been empirically established, and the contingency of recasts is argued to be the key. However, the efficacy of recasts in computer-mediated communication (CMC), text-based online chatting in particular, remains...
