Transparent conductive film on plastic substrate is a critical component in low-cost, flexible, and lightweight optoelectronics. Industrial-scale manufacturing of high-performance transparent flexible needed to enable wide-ranging applications. Here, we demonstrate continuous roll-to-roll (R2R) production based metal nanowire network fully encapsulated between graphene monolayer substrate. Large-area grown Cu foil via R2R chemical vapor deposition process was hot-laminated onto nanowires...
This study introduces Expectancy-value motivation theory to explain the paths of influences from perceptions test design and uses preparation as a special case washback on learning. Based this theory, two conceptual models were proposed tested via Structural Equation Modeling. Data collection involved over 870 takers College English Test Band 4 in China. A perception assessment questionnaire was given at beginning 10-week period; eight weeks later. who endorsed high-stakes, instrumental...
This article reports an empirical study that examined the pattern of test preparation for College English Test Band 4 (CET4) and differential effects practices on its scores, thereby drawing implications CET4 score validity. Data collection involved 1,003 takers CET4. A pretest was administered at beginning a 2-month period; posttest questionnaire were about 9 weeks later. Multiple regression structural equation modeling used in data analysis. The found better explained by perceived...
This study was conducted with two goals in mind: (1) to explore the mediating roles of L2 enjoyment as a positive emotion and anxiety negative relationship between Informal Digital Learning English (IDLE) willingness communicate (L2 WTC) an exam-oriented EFL context, (2) further examine whether gender educational stage play any role these relationships. Participants include 1,265 Korean learners (764 secondary 501 tertiary students; 400 males 865 females). Moderated mediation structural...
Abstract Conventional conductive materials such as metals are crucial functional components of systems in diverse electronic instruments. However, their severe intrinsic impedance mismatch with air dielectric causes strong reflection incident electromagnetic waves, and the resulting low transmissivity typically interferes surrounding signal communications modern multifunction‐integrated Herein, graphene glass fiber fabric (GGFF) that merges electrical properties attributes highly porous...
Uniform tellurium single crystal nanorods with diameters of 14 nm and lengths 300 were prepared through reduction [TeS4]2− by SO32− use a suitable surfactant, sodium dodecyl benzenesulfonate (NaDDBS). Te various can be carefully adjusting the concentration NaDDBS or initial TeS42−. The nucleation growth processes interpreted solid–solution–solid transformation surfactant-assisted mechanism.
The study utilised a fine-grained diagnostic checklist to assess first-year undergraduates in Hong Kong and evaluated its validity usefulness for diagnosing academic writing English. Ten English language instructors marked 472 essays with the checklist. They also agreed on Q-matrix, which specified relationships among items five subskills. This conceptual Q-matrix was refined iteratively via fitting psychometric model (i.e. reduced reparameterised unified model) empirical data marks) through...
Purpose This study (1) used a person-centered approach to identify specific subgroups of 1,265 EFL learners who participated in Informal Digital Learning English (IDLE) activities, and (2) looked at how different IDLE profiles are related important affective variables.Design/Methodology : To profiles, we cluster analysis.Findings The L2 motivation, enjoyment, anxiety, grit levels the IDLErs with distinct differed significantly. When compared Profiles 1 (Minimal IDLErs: 33%), 2...
This study examined test takers' perception of assessment demand and its impact on the measurement intended constructs. More than 800 takers took a pre- posttest College English Test Band 4 filled in questionnaire to report skills they perceive as necessary for answering test. The found perceived language test-taking equally necessary. Perception linguistic knowledge negatively affected performance reading test, while perceptions positively essay seemed affect construct, although effects are...
Abstract Discourse competence is an essential component of communicative and central to the mastery academic writing. This article reports a three-tiered diagnostic assessment two English as foreign language (EFL) student writers’ discourse in terms textual features, composing strategies, knowledge about Drawing on extensive analyses their writing samples, writer logs, semi-structured interviews, we identified discourse-level weaknesses examined strategies status ascertain relationships with...
Writing in 1991, Stiggins defined assessment literacy (AL) as the knowledge and skills needed for measuring student achievement, stressing base that teachers need order to conduct sound assessment.Drawn from this general concept, language (LAL
This article describes the steps we went through in designing and validating an item bank to diagnose linguistic problems English academic writing of university students Hong Kong. Test items adopt traditional formats (e.g., MCQ, grammatical judgment tasks, error correction) but are based on authentic language materials extracted from a manually error-tagged corpus target students' essays. A total 257 were developed assess 25 high-frequency grave errors. To validate test calibrate their...
Medical image classification is an essential task in the fields of computer-aided diagnosis and medical analysis. In recent years, researchers have made extensive work on by computer vision techniques. However, most current based deep learning methods, which still suffer from expensive hardware resources, long time consuming a lot parameters to be optimized. this paper, multi-granularity ensemble algorithm for broad system proposed, end-to-end lightweight model. On one hand, proposed method...
This study explores the effectiveness of Data-Driven Learning (DDL) in teaching noun collocations to pre-tertiary learners Hubei Province, China, using online corpus tool 'Corpusmate'. Acknowledging importance and challenge mastering learning a foreign language, this focuses on effects DDL learners, an area less examined previously due complexities associated with tools. Conducted over two months, research employed pre-tests, post-tests, delayed post-tests measure learners' comprehension...
AbstractThis paper describes the development and validation of an item bank designed for students to assess their own achievements across undergraduate-degree programme in seven generic competences (i.e., problem-solving skills, critical-thinking creative-thinking ethical decision-making effective communication social interaction skills global perspective). The Rasch modelling approach was adopted instrument validation. A total 425 items were developed. content validity these examined via...
