Translanguaging pedagogy has widely attracted interests from studies of second or foreign language teaching. Corrective feedback has long been recognized for its value on improving second language learning outcomes. However, limited attention has been given to the potential influence of translanguaging in the process of corrective feedback on learners’ second language writing performance, especially the influence of oral corrective feedback. This paper aims at exploring the effects of translanguaging in tutors’ oral corrective feedback (OCF) on Chinese EFL learners’ argumentative writing in six-week writing tutorials. 12 first-year Chinese college students and a Chinese tutor of English participated in the study at a university in Central China. The findings showed positive effects of translanguaging in OCF on Chinese EFL students’ argumentative writing performance. It attempts to make some contributions to EFL writing instruction. Teachers can alter their monolingual medium of English only to adapt to students’ needs, focus on students’ language practices, and create a language education ecological environment through translanguaging pedagogy.

While the past two decades have witnessed enormous growth in research on student engagement with feedback on second language (L2) writing, little attention has been paid to student engagement with peer feedback longitudinally through peer feedback interaction. This study explored how 12 students engaged with peer feedback cognitively, behaviorally, and affectively over a semester of L2 writing and learning, and what factors influenced student engagement. Data were collected from peer feedback dialogue, multiple drafts of compositions, retrospective verbal reports, feedback notes, self-reflection, and focus groups. Data were analyzed through text analysis, content analysis, and thematic analysis. The findings revealed that student engagement with peer feedback varied over four writing tutorials. Face-to-face peer feedback contributed to maintaining sustainable student engagement with peer feedback. Other learner-related factors such as learner beliefs, language proficiency, product-oriented mindset, and context-related factors such as task requirements, feedback-related issues, and interaction patterns jointly influenced student engagement.

This study examined how Chinese college teachers developed their Technological Pedagogical Content Knowledge (TPACK) by situating the learning process in three interactive activity systems during teaching English as foreign language (EFL) online in China. Data were collected from teachers’ diaries, in-depth interviews, and various records of online teaching. Findings indicated that teachers employed cultural artifacts, social relations, and beliefs and concepts to cope with difficulties that confronted their online teaching. They also performed sideways moves to new activities that provided systemic implications for the previous form of activity. Hence, the teachers constructed their TPACK through bi-directional learning within and between an online teaching activity system and its two interactive systems. This study highlighted the situativeness and distribution of TPACK development, and assumes significance in sustainable teacher development and further integration of information and communication technology (ICT) in English language teaching.

Teacher emotion has become an important issue in English language teaching as it is a crucial construct in understanding teachers' responses to institutional policies. The study explored teachers' emotion labor and its impact on teachers' pedagogical decision-making in English for Specific Purposes (ESP) teaching in a university of Traditional Chinese Medicine (TCM) in China. Drawing on a poststructural perspective, the study examined data from two rounds of semi-structured interviews, policy documents and teaching artifacts. The analysis of data revealed that the major emotion labor facing the participants revolved around students' disengagement in class. Teachers experienced mixed feelings of anticipation, disappointment, anger, and empathy toward students and distanced themselves from institutional feeling rules enforcing objective assessment of students' performance and punishing students for lack of engagement in class. The study found that teacher emotion labor served as the site for their pedagogical modifications. ESP teachers' beliefs in the importance of attending to students' needs become a powerful discourse in supporting teachers to strategically subvert institutional feeling rules and critically reflect on the dysfunctions of curriculum, orienting teachers' agentic actions in modifying pedagogical practices. We thus underscore this empowering discourse as the bridge to connect teachers' policy negotiation and their actual classroom practices. We also highlight teachers' pedagogical decision-making as a process of the interactions of teacher emotion, teachers' reflexive practices, and power relations. The study ended by suggesting more longitudinal research where teachers' beliefs as previously appropriated discourses could be examined comprehensively as they were both the construct of emotion labor and the potential subverting power in supporting teachers' pedagogical decision-making in policy negotiation.

Preterm birth and feeding are the most important pathogenic factors of neonatal necrotizing enterocolitis (NEC). Metabonomic has been widely used in the diagnosis and treatment of other diseases, but there is no research on the related diseases of premature infants. Compared with full-term infants, the metabolism of preterm infants has its own specificity, so it can easily lead to NEC and other digestive tract inflammatory diseases. Metabonomic may be applied to the diagnosis of preterm related diseases, such as NEC. The model was established with premature infant serum samples from 19 premature infants in our hospital, which was compared with the full-term infant control group. Serum was analyzed by gas chromatography-mass spectrometry (GC-MS), coupled with the analysis of serum metabolic characteristics. The variable important in projection, P value and Pearson correlation coefficient of samples were analyzed by using SIMCA, SPSS and other multivariate statistical analysis software. Compared to the term infants, premature infants had significantly higher levels of luteolin, and lower levels of xylose, O-succinyl-L-homoserine and lauric acid in the serum. There were some correlations among several different metabolites and clinically related indices (albumin, total bilirubin) for premature birth related diseases. There are metabolic alterations in the serum of premature infants, which make contribution to the diagnosis of NEC.
