The participants involved in this study were 7 beginners learning Mandarin in a Chinese university whose native languages were totally different. Multiple sources of data were collected, including classroom observations, semistructured interviews and stimulated recalls. The results indicate that the students with higher level of WTC were more fluent in L2 Chinese communication, and the student whose native language or second language is Russian performed better in Chinese communication.展开更多

Some techniques, such as the calculus of variations, energy analysis method, commutativity of the products of difference operators, decomposition of high-order difference operators and the theory of a priori estimates are introduced and an optimal order error estimates in l^2 norm is derived. This method has been applied successfully to the numerical simulation of enhanced oil production in actual oilfields, and the simulation results ate quite interesting and satisfactory.展开更多

Wang proposed and analyzed superconvergence of the conforming finite element method by L2-projections. The goal of this paper is to perform numerical experiments using MATLAB to support and to verify the theoretical results in Wang for the superconvergence of the conforming finite element method (CFEM) for the second order elliptic problems by L2-projection methods. MATLAB codes are published at https://github.com/annaleeharris/Superconvergence-CFEM for anyone to use and to study.展开更多
