Using recasts to enhance students’ English question production: Ethiopian secondary school students in focus

open access: yesCogent Education
Research on recasts has gotten increasing attention from SLA researchers ever since 1990s. However, the studies on the effectiveness of recasts had inconsistent findings and are still debatable in what way recasts facilitate L2 learning.

The role of extensive recasts in error detection and correction by adult ESL students

open access: yesStudies in Second Language Learning and Teaching, 2016
Most of the laboratory studies on recasts have examined the role of intensive recasts provided repeatedly on the same target structure. This is different from the original definition of recasts as the reformulation of learner errors as they occur ...

Input, interaction and second language development : an empirical study of question formation in ESL [PDF]

open access: yes, 1999
This study examines the relationship between different types of conversational interaction and SLA. Long's (1996) updated version of the interactionist hypothesis claims that implicit negative feedback, which can be obtained through negotiated ...

Recast frequency and the acquisition of English articles in a computer-mediated context

open access: yesStudies in Second Language Learning and Teaching
This study examines the role of recast frequency and its effectiveness in the acquisition of English articles in a computer-mediated context. Sixty-one pre-intermediate university language learners in Turkey were randomly divided into four main groups ...

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Synergistic Integration of Liquid Crystalline Ordering and Dynamic Networks for Ultrarobust Bismaleimide Vitrimers

open access: yesAdvanced Functional Materials, EarlyView.
A liquid‐crystalline bismaleimide vitrimer integrates local mesogenic organization with exchange‐active ester connectivity, achieving a glass‐transition temperature near 300°C while remaining reprocessable. Stress‐relaxation analysis and temperature‐dependent remolding reveal how segmental mobility, network rearrangement, and structural integrity ...

The effects of implicit corrective feedback on production of lexical stress in L2 English

open access: yesStudies in Second Language Learning and Teaching
The interactionist approach to second language acquisition has yielded a plethora of studies confirming the positive impact of interaction and corrective feedback on second language (L2) development.

Recasts vs. direct corrective feedback on writing performance of high school EFL learners

open access: yesCogent Education, 2018
There might always be errors during the learning process which need correction; accordingly, providing corrective feedback is critical. However, the various types of feedback applied during classes affect the learning and teaching process.

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

open access: yesAdvanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

open access: yesAdvanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.
