Teachers’ Beliefs and Practices Regarding Assessment in English as a Foreign Language Classrooms in Vietnam

Task-based language teaching (TBLT) has generated worldwide popularity as a curriculum innovation, and extensive research has investigated various aspects of the approach. However, little is known about the implementation of classroom assessment in TBLT curricula. This study investigated high school English as a foreign language teachers’ beliefs and practices regarding assessment in a curriculum innovation context in Vietnam. Data comprised in-depth interviews with six teachers, as well as testing documents. The findings revealed a strong impact of the high-stakes exams on teachers’ testing beliefs in that they focused explicitly on linguistic items in the assessed content and forms of assessment. These beliefs were accurately reflected in their testing practices. However, both the teachers’ beliefs and practices were contradictory to teaching principles and the expectations of the intended curriculum. These findings suggest that in-service teacher professional development programs are necessary for innovations like TBLT to have a real change in the classroom

High school EFL students’ beliefs about oral corrective feedback: The role of gender, motivation and extraversion

This study employed an explanatory sequential mixed-methods research design to examine the beliefs of Vietnamese EFL students concerning oral corrective feedback (CF) and the role of some individual differences in these beliefs. The data consisted of questionnaires completed by 250 Vietnamese high school students and follow-up interviews with 15 of them. Exploratory factor analysis revealed six latent factors underlying students’ beliefs about CF, namely, (1) output-prompting CF and eliciting recasts, (2) desire for CF, (3) non-verbal cues, (4) important errors, (5) input-providing CF, and (6) less important errors. Descriptive statistics and thematic analysis of the interviews showed that students were positive about CF. They liked both input-providing CF and output-prompting CF for all error types. Metalinguistic feedback was the most strongly preferred, while clarification request was the least preferred. Further statistical analyses revealed some interesting relationships between students’ beliefs about CF and their gender, English learning motivation, and self-rated introversion/extraversion. Females were more positive about CF than males, and extraverted females were more positive about input-providing CF than introverted females. Also, students learning English for exams were more positive about CF than those learning English for communication. Pedagogical implications for effective feedback provision in EFL contexts are discussed

Sustained Content Language Teaching: Insights from an ESL and EFL course

Instructional settings (English as a second language (ESL) and English as a foreign language (EFL)) may provide different opportunities for learners’ meaningful language use. This qualitative study was designed to shed light on this issue. The data included multiple sources collected from a sustained content gastronomy language course taught in an American ESL and a Taiwanese EFL context. Findings revealed that various factors (e.g., themes, environment, and learners) contributed to learners from both contexts meeting course goals. The findings further indicate that it is not the ESL/EFL context but instead using a sustained content language teaching approach that incorporates theme-based instruction and dynamic units that ensures learners are provided opportunities for meaningful and purposeful language use

Driving Factors for Green Innovation in Vietnamese Construction Enterprises

Purpose: The aim of this study is to examine the influences of different factors on green innovation in Vietnamese construction enterprises.   Theoretical framework: The theoretical framework is built upon the resource-based view, the model of organizational innovation, and stakeholder theory.   Design/methodology/approach: The research carries out a literature survey related to construction enterprises, then empirical analysis is conducted among 450 employees and managers at all level working in this field with the results analyzed using Cronbach’s Alpha analysis, exploratory factor analysis, pearson correlation analysis, linear regression analysis and One - way ANOVA analysis.   Findings: The results demonstrate that using renewable energy is well represented for green innovation in the Vietnamese construction industry and quantitative results also show positive impacts of all factors studied on green innovation: Green dynamic capabilities, Green creativity, Green knowledge sharing, Corporate environmental ethics, Pressure from industry competitors and regulators. In addition, the result affirmed there are statistically significant differences in the level of green innovation between construction enterprises of size and age, but not types of firm.   Research, Practical & Social implications: The study proposes solutions for both enterprises and regulators – one of the external stakeholders to develop green innovation in the construction sector. 

PROBLEMS OF ENGLISH STUDIES STUDENTS ON LEARNING PHONOLOGY AND SUGGESTIONS, CAN THO UNIVERSITY, VIETNAM

The writers were concerned by the phonological challenges encountered by students of the Schools of Foreign Languages, Can Tho University. Foreign language majors are often difficult, and theory is quite tackled, which has caused many serious problems for students. This is no exception for students majoring in English Studies, at Can Tho University in the process of approaching the subject "Introduction to English Phonology". This study was conducted to clarify the phonological challenges that students at Can Tho University are facing, as well as suggest solutions to the problem of phonology learners. Using data from Google Questionnaire Forms, the research conducted an error analysis of 103 English majors who studied the subject. Based on the phonological problems, certain remedial activities were planned for the students, which helped improve their study process phonological problems considerably.   Article visualizations

Socio-Cultural Factors Challenging Development Interventions in Cattle Production in the Remote Areas of Vietnam

The northwest highlands of Vietnam are characterized by high altitude, low infrastructure, and low population densities composed of a wide diversity of different ethnic groups. Their socio-cultural characteristics strongly influence their lifestyle and production systems, including agricultural activities. The majority of these people have suffered from slow economic development, with the highest poverty rate in the country. This is a real need for plausible interventions where behavioral changes of smallholders throughout local value chains would be a critical foundation. Our project implemented in this context of development in the Northwest highlands of Vietnam aims to understand the role of socio-cultural factors in cattle production systems in order to propose and examine feasible technical and marketing interventions to improve local grazing-based cattle production. Data on farmers and other actors (collectors, slaughterhouses, retailers and consumers) in local cattle value chains of two selected provinces (Son La and Dien Bien) were collected at the beginning of the project via a baseline survey. In addition, different group discussions with farmers were conducted until the end of the project to monitor the project’s progress and changes created through its interventions. We found that such behavioral changes cannot be motivated by development interventions per se without integrating an understanding of socio-cultural factors (i.e. ethnicity, geographical location and grazing-practices)

NOWJ1@ALQAC 2023: Enhancing Legal Task Performance with Classic Statistical Models and Pre-trained Language Models

This paper describes the NOWJ1 Team's approach for the Automated Legal Question Answering Competition (ALQAC) 2023, which focuses on enhancing legal task performance by integrating classical statistical models and Pre-trained Language Models (PLMs). For the document retrieval task, we implement a pre-processing step to overcome input limitations and apply learning-to-rank methods to consolidate features from various models. The question-answering task is split into two sub-tasks: sentence classification and answer extraction. We incorporate state-of-the-art models to develop distinct systems for each sub-task, utilizing both classic statistical models and pre-trained Language Models. Experimental results demonstrate the promising potential of our proposed methodology in the competition.Comment: ISAILD@KSE 202

Effect of the feeding condition and number of dominant follicles on oestrus synchronization in Swamp buffalo

The research aimed to assess how feeding conditions and the number of the dominant follicles (DF) influence oestrus synchronization in swamp buffaloes. A total of 170 swamp female buffaloes raised in semi-grazing and housekeeping were included in the study. The synchronization used CIDR method and the follicles on the day of CIDR (Controlled Internal Drug Releasing) insert and removal were tracked by sonography. The results indicated that the age of first mating, age at first calving, and caving interval showed no significant differences in the two feeding conditions. The number of follicles at CIDR insertion and removal decreased in semi-grazing, but increased in housekeeping buffaloes. The percentage of buffalo without DF, one DF, and two DFs at CIDR withdrawal did not differ statistically. The percentage of estrus was 100% in both groups. Pregnancy rates were 53.18% in semi- grazing and 52.63% in housekeeping. The onset of oestrus was similar, but the duration of oestrus was longer in the buffaloes without DF than those with one or two DFs. The percentage of pregnant buffaloes in the group without DF was significantly lower than that in the other two groups. In summary, the efficiency of oestrus synchronization did not differ between semi-grazing and housekeeping methods. Buffaloes without DF displayed longer oestrus periods and lower pregnancy rates compared to those with one or two DFs in the ovarian system
