How does Alignment Work in the Continuation Task by Advanced EFL Learners:A Case Study

The continuation task (Wang & Wang, 2014) proves to have language learning potentials by many empirical studies (Peng, 2018). This study intends to explore its underlining alignment mechanisms through two continuation tasks on English materi-als called Chon and Charles by two Chinese linguistics-major graduates (EFL learners). The results show that alignment is ubiqui-tous both linguistically and thematically, and the reading and writing are tightly coupled. This indicates that the continuation task will significantly benefit second language writing pedagogy if applied appropriately.

Geometric analysis of investment casting turbine blades based on digital measurement data

A turbine blade is one of the key components of the aero-engine. Its geometric shape should be inspected carefully in the production stage to ensure that it meets the tolerance specification. In the present paper, an approach for investment turbine blade geometric shape analysis based on multi-source digital measurement is presented. Its key technologies, such as measurement data collection, blade model reliable alignment, geometric shape deviation fast calculation and visualization, were investigated. Actual measurement data from a structure light measurement device and a Coordinate Measuring Machine(CMM) for turbine blades were used to validate the presented method. The experimental results show that the proposed method is accurate, quick and effective to implement.

Sign and indexicality:a case study of enhancing alignment of situation models in SCWT

The story continuationwriting task(SCWT)is anewly emerging proficiency test of National Matriculation English Test(NMET)in three provinces in China.Nevertheless,little is known with respect to how test-takers enhance their alignment of situation models in SCWT.This paper reports on a case study of the development of situational alignment of one L2(second language)learner in a senior high school in Jiangsu Province,China,drawing on qualitative data collected via individual faceto-face interviews,and supplemented by face-to-face conversations and email exchanges,over a period of one year.This study investigates how the test-taker enhances her alignment of situation models,and what factors contribute to her development of situational alignment under the framework of a new semiotic research finding,a pan-indexicality model.This paper concludes that test-takers possess the capacity of developing their alignment of situation models,and that a pan-indexicality model,affording opportunities for test-takers to accurately decode the meaning of a linguistic sign at the overall sense level,plays a decisive role in identifying and integrating key dimensions of situation models and eventually enhancing test-takers’situational alignment.This study suggests that a pan-indexicality model can be employed by test-takers to understand the meaning of a linguistic sign at the overall sense level,and test-takers’encyclopedic knowledge,contextual information,and personal emotions regarding a linguistic sign should be highlighted in classroom instruction to help test-takers construct aligned situation models in SCWT.
