International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT In English medium instruction (EMI), students face cognitive and emotional demands in second language (L2) communication, which may hamper their motivation and willingness to communicate (WTC). Adopting a mixed‐methods design, this study explores how growth mindsets affected student motivation (e.g., ideal L2 self and ideal disciplinary self ...

Zhongguo youzhi为了提高单螺杆挤出机中花生蛋白的挤出品质，基于拉伸应力的破碎效应，以传统单螺杆挤出机为参照，利用有限元软件CFX计算了花生蛋白在流场中的运动情况，通过压力场、速度流线场以及应变速率场，分析新型混炼单螺杆挤出机的特性，并以拉伸流变学理论对设计原理进行验证，同时采用响应面法对新型混炼单螺杆挤出机的工艺参数进行优化。结果表明：新型混炼单螺杆挤出机中混炼元件的分流作用使得沿挤出方向产生了压力降，物料发生回流，导致建压性能降低，从而延长了停留时间，此处因回流效果产生的局部高压也有利于压延 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...
