Abstract Praxis , according to the Vygotskian thoughts and tenets, entails unity of dialectical relationship between theory practice. As a vital concept grounded in sociocultural theory, praxis has received increasing attention among language teacher education scholars, typically over recent years (e. g., Johnson et al., 2020, 2022). Yet, there remains scant research through lens, thus requiring extended efforts from researchers. To join existing literature bridge gap, we explored how -...

Classification consistency and accuracy are viewed as important indicators for evaluating the reliability validity of classification results in cognitive diagnostic assessment (CDA). Pattern‐level indices were introduced by Cui, Gierl, Chang. However, at attribute level have not yet been constructed. This study puts forward a simple approach to estimating both pattern through one single test administration. Detailed elaboration is made on how upper lower bounds attribute‐level can be derived...

Thermosensitive hydrogels with periodic dielectric structures displaying tunable structural color by temperature stimuli have attracted much research interest recently. However, reported thermosensitive photonic either using the poly(N-isopropylacrylamide) (PNIPAM) bulk hydrogel as responsive matrix or PNIPAM microgels building blocks poor mechanical strength. Moreover, expensive and time-consuming preparation process also limits their further application. In this work, a different strategy...

Intelligent fibers with a structural color have wide applications in many cutting-edge fields and attracted significant attention recent years. However, most reported optical fixed because hard colloids were used as blocks of photonic crystals. Herein, we developed simple scalable method to realize hydrogel dynamic using soft thermoresponsive microgels blocks. A full interpenetrated sodium alginate-polyacrylamide fiber was prepared through an exclusion process, which is facile for scaled-up...

Cardiac surgery and thoracic can have multiple impacts on patients’ pulmonary function. This article analyzes the related effects from three aspects: limited ventilation function, gas exchanges dysfunction increased risk of postoperative complications. At same time, perioperative nursing measures were proposed for different types patients, including preoperative, intraoperative, nursing, detailed data was used to analyze effectiveness. It’s hoped provide practical guidance clinical patients...

With the purpose to assist subject matter experts in specifying their Q-matrices, authors used expectation-maximization (EM)-based algorithm investigate three alternative Q-matrix validation methods, namely, maximum likelihood estimation (MLE), marginal (MMLE), and intersection difference (ID) method. Their efficiency was compared, respectively, with that of sequential EM-based δ method its extension (ς2), γ method, nonparametric terms correct recovery rate, true negative positive rate under...

Chameleons are famous for their quick color changing abilities, and it is commonly assumed that they do this camouflage. However, recent reports revealed chameleons also change body temperature regulation. Inspired by the structure of panther chameleon's skin, a stripe-patterned poly(N-isopropylacrylamide) (PNIPAM) polyacrylamide (PAM) hydrogel film with laminated fabricated in work; thus, both camouflage thermoregulation can be achieved through controlling Vis NIR light effectively. For...

Abstract The distinguishing feature of dynamic assessment (DA) is the dialectical integration and instruction. However, how to design targeted instruction or mediation has been relatively underexplored. To address this gap, study proposes attribute‐based model (AMM), an English‐as‐a‐foreign‐language listening based on item attributes (constructs) derived from cognitive diagnostic (CDA). CDA provides theoretical methodological support for accurate correspondence items via Q‐matrix development...

Motivation has been recognized as a vital component in successfully learning second or foreign language. However, research on language learners' motivation study abroad context requires more attention an era which international mobility is becoming new normal. This investigated 217 Chinese overseas university students' L2 during their one-year postgraduate the United Kingdom. by examining range of motivational variables relation to motivated English behaviors. Integrating results from both...

English as Foreign Language (EFL) learners’ cognitive processes have been a research focus in listening assessment. Most studies use correct responses data, but undervalue the rich information of incorrect answers or options (in case multiple choice questions, MCQ). However, MCQ distractors are often intentionally designed to reveal problems barriers. In order diagnose EFL barriers through responses, Cognitive Diagnostic Models (CDMs) for bugs were adopted, hence name Bug-CDMs. First, five...

[1] In the paper “Intercomparison of pressure standards (Au, Pt, Mo, MgO, NaCl and Ne) to 2.5 Mbar” by S. M. Dorfman et al. (Journal Geophysical Research, 117, B08210, doi:10.1029/2012JB009292, 2012), caption Figure S3 in auxiliary material was incorrect. The correct caption, which appears correctly readme file, is “Differential stress measured Ne Ar compared measurements Pt Au samples.”

In nature, some creatures can change their body shapes and surface colors simultaneously to respond the external environments, which greatly inspired researchers in development of color-tunable soft actuators. this work, we present a facile method prepare smart hydrogel actuator that bend bidirectionally color simultaneously, just like an octopus. The is fabricated by elastomer/hydrogel bilayer layer was decorated with thermoresponsive microgels as photonic crystal blocks. Compared...

Abstract The gaps both in east-west China and urban-rural development affect English education northwest rural areas. Reading comprehension, as the foundation for secondary school students’ overall development, is need of tailored mediation. Level 3 China’s Standards (CSE3) can be used to inform Dynamic Assessment (DA) test items mediation model. With CSE3-based reading materials DA model, current study applied five sessions one-on-one an experimental group. Results show that group...

Based on the development in dealing with nonlocal boundary conditions, we propose a seamless local-nonlocal coupling diffusion model this paper. In our model, finite constant interaction horizon is equipped part and transmission conditions are imposed co-dimension one interface. To achieve coupling, introduce an auxiliary function to merge local design proper condition ensure stability convergence. addition, by introducing bilinear form, well-posedness of proposed can be proved convergence...
