4. Investigation of a Chinese Character Writing App: Learners' Perspectives

Author

Zhou, Wenying and Li, Xiaoshi

Abstract

Many people who learn Chinese as a foreign language (CFL) have encountered challenges when it comes to character writing. This was a follow-up study of our quantitative study in 2019 that showed that mobile app was a significantly more effective method than pen-and-paper method to learn Chinese character writing. Thirty beginning CFL learners participated in this study. Surveys and interviews were conducted to seek their perspectives on the role of stroke order knowledge, the use of the mobile app in Chinese writing, and suggested ways to teach Chinese character writing. As shown in the results, findings demonstrated that the participants recognized the value of the app in their character learning. They held the view that stroke order not only plays an important role in Chinese writing, but also should be emphasized at the beginning level. Although the use of the app was favored, compared with the conventional pen-paper method, a mixed method of both was suggested for pedagogical practices.

Abstract

Elementary Chinese II is aimed at those who have learned Chinese as a second/foreign language for one semester, using the OER textbook “Elementary Chinese I“. This open textbook contains six main lessons, including topics such as school life, shopping, transportation, weather, eating out, and asking and giving directions. They are organized in a straightforward and well-structured manner that are easy to follow. Within each lesson, there are a set of two dialogues or a set of one dialogue plus one narration. The texts of the dialogues or narrations are created to provide real-life Chinese language to beginning learners. After the texts, vocabulary words are listed for them to study and review. Grammatical points are explained in English and example sentences are provided for students to understand. Each dialogue or narration ends with culture notes where learners can read and better understand the target text.

31. Chinese Dual-Language Bilingual Education Teachers' Pedagogical and Languaging Practices in American Immersion Schools

Author

Zhou, Wenying and Li, Guofang

Abstract

Based on video recordings of five pre-k to grade 4 Chinese dual-language bilingual education (DLBE) teachers' classroom instruction, this article examines the Chinese DLBE teachers' target and first language use and pedagogical moves during their processes of learning to teach in immersion schools in the US. Conversational analyses of classroom interactions show that the teachers' subscribed to target language (TL) only instruction with minimum translanguaging and that teacher-fronted talk in the TL dominated their teaching with low student language output. Although their attention to curriculum-related content varied depending on lesson focus and student TL proficiency, a significant amount of teacher languaging practices was for classroom management. The findings have important implications for Chinese DLBE teachers' preparation and professional development.

Abstract

A composite foam consisting of foamed cross-linking polystyrene (c-PS) and boron nitride nanosheets (BNNSs) was synthesized, which shows a higher thermal conductivity (TC) than the corresponding solid counterparts. The BNNS fillers are found to be aligned along the cell wall as a result of the biaxial stress field from cell expansion during the formation of three-dimensional interconnectivity in the foams, resulting in an enhanced TC of 1.28 W/m K, nearly two and four times those of its solid counterpart and pure c-PS, respectively. It is found that the foaming-assisted formation of the filler network is an efficient strategy to improve the TC at low filler loadings in the composites. Furthermore, the composite foams exhibit low density, rather low dielectric constants and dissipation factors at wide frequency and temperature ranges. The present work provides a novel approach to design and prepare lightweight heat conductive polymers with low filler loadings as low-density heat management materials for potential applications in aeronautics and aerospace components.
