Can I teach these students? A case study of Vietnamese teachers’ self-efficacy in relation to teaching English as a foreign language

The study looked at factors that influenced the self-efficacy in teaching English as a Foreign Language (EFL) of a group of university teachers in Vietnam. Previous studies yielded contradictory results regarding the sources of self-efficacy information. Very little empirical research on the potential role of cultural factors on self-efficacy and on teachers’ self-efficacy in EFL contexts has been done. Researchers disagree on whether participating in a new setting can enhance teachers’ self-efficacy beliefs. Therefore, this study explored the relationship between Vietnamese teachers’ discourses of effective teaching practices and their self-efficacy beliefs, the influence of Vietnamese culture and context on teachers’ self-efficacy beliefs, and whether participating in the research led to a change in the self-efficacy beliefs of the teacher participants and of myself as researcher. The research took the form of a qualitative case study. Participants were eight university teachers of the English language at a technical university in Vietnam. Data collection lasted six months. Data collection tools included focus group discussions, individual interviews, journaling, and observations. An inductive coding process and thematic analysis were used for analysing data. Findings indicate that social persuasion was the most influential source of self-efficacy information. The study shows that different sources of self-efficacy information interacted with one another to influence the two dimensions of self-efficacy. Besides, it appears that teachers’ understanding of a number of environment and workplace factors appeared to constrain some teachers into adopting the Grammar Translation Method (GTM) approach and possibly reduced their self-efficacy in adapting a Communicative Language Teaching (CLT)-oriented approach. After participating in the study, the teaching approaches of study teachers and my own approaches seemed to be more CLT-oriented although most of us were characterised by a low sense of self-efficacy in adapting this approach in the Vietnamese classrooms. I also developed an enhanced sense of self-efficacy in doing the thesis. Findings suggest that several aspects of Vietnamese culture, e.g. the concept of face, are likely to have influenced the way the study teachers selected, weighted and interpreted efficacy-building information. There were certain features of context, e.g. the state of leadership practices, which may have affected what constituted sources of self-efficacy information and how they operated. In addition, it is plausible that changes in context, e.g. teaching different kinds of students, led to a change in the way the teachers and I weighed and selected self-efficacy information. Self-reflection, self-doubt and self-regulation were other factors causing fluctuations in the study teachers’ and my self-efficacy. My study contributes to a widening understanding of how different aspects of culture can impact on self-efficacy. It provides examples to challenge the claim that the self-efficacy of experienced teachers is stable and the widespread view that a negative sense of self-efficacy induces individuals to give up and make less effort. The study shows the relationship between teacher self-efficacy beliefs and their discourses of EFL instruction, i.e. their self-efficacy in using different aspects of a communicative approach fluctuated at different stages of the study. The study points to the need to improve leadership practice and teaching conditions at the faculty and university. Preparing teachers for regulation strategies, encouraging them to work collectively, and offering more professional development programs are likely to develop a stronger sense of self-efficacy among teachers. It would be useful if future research could focus more on classroom observations to avoid the reliance on self-report data. More studies on the influence of culture on teacher self-efficacy with an inclusion of scales to measure different cultural factors are needed. Longitudinal studies are desirable in understanding changes in teacher self-efficacy under the influence of context

A research on the performance of down-flow hanging sponge (DHS) reactor treating domestic wastewater

The aim of this study was to evaluate the performance of a down-flow hanging sponge (DHS) system in treating domestic wastewater. A pilot-scale of DHS system with a capacity of 60 L was designed and fabricated from polyvinyl chloride (PVC). The dimensions of DHS system are 1.5 m in height and square surface with 0.2 m in width, consists of three identical segments connected vertically in series. Each segment was filled by polyurethane sphere containing sponge. The total area of sponge and polyurethane sphere was 3,300 m2 m-3, density at 150 kg m-3, void ratio at 90%. DHS system was operated at ambient temperature within 82 days and stepwise increased of organic f rate from 0.5 to 1 and 1.5 kg COD m-3 d-1. The results showed that, this system performed well throughout the operational period and achieve the maximum removal of COD, BOD5, NH4+-N, and TN as 80%, 83%, 65% and 60%. The effluent of wastewater from DHS system achieved the requirement for National technical regulation on domestic wastewater of Vietnam type B QCVN 14:2008/BTNMT. In conclusion, the performance of DHS system indicated a high potential for application in removing organic matter and converting nitrogen ammonia to nitrogen nitrate, however it did not perform well for the removal of total nitrogen, it is necessary to study further by providing an anoxic zone in the system to enhance the treatment of nutrient in wastewater

Nutritional status and dietary intake before hospital admission of pulmonary tuberculosis patients

Conducting research on nutritional status and dietary intake of pulmonary tuberculosis patients is essential for developing interventions in clinical nutrition practice and treatment during hospitalization, which can improve the quality of patients life. This cross-sectional descriptive study aimed to determine nutritional status and some related factors (such as geography, occupation, educational level, economic classification, etc.) of 221 patients with pulmonary tuberculosis who were examined and treated at the Respiratory Tuberculosis Department, National Lung Hospital in July 2019–May 2020. The results showed that the risk of undernutrition: According to BMI (Body Mass Index): 45.8% of patients were malnourished, 44.2% normal and 10.0% overweight/obese. According to MUAC (Mid-Upper Arm Circumference): 60.2% of patients were malnourished, 39.8% of patients were normal. According to SGA (Subjective Global Assessment): 57.9% of patients were at risk of undernutrition, of which 40.7% were at moderate risk of undernutrition and 17.2% risk of severe undernutrition. Classification of nutritional status according to serum albumin index: 50% of patients were malnourished, the rate of undernutrition of mild, moderate and severe levels was 28.9%, 17.9% and 3.2%, respectively. Most patients eat with others and eat less than four meals a day. The average dietary energy of patients with pulmonary tuberculosis in was 1242.6 ± 46.5 Kcal and 1084 ± 57.9 Kcal, respectively. 85.52% of patients did not eat enough food, 4.07% had enough, 10.41% consumed excess energy. The ratio of energy-generating substances in the diet (Carbohydrate:Protein:Lipid) was on average 54:18:28 for males and 55:16:32 for females. Most of the study population had diets that did not meet the experimental study in terms of micronutrient content. Specifically, more than 90% do not meet the requirements for magnesium, calcium, zinc, and vitamin D. The water-soluble and fat-soluble vitamins respond poorly, only about 30–40%. Selenium is the mineral with the best response rate, above 70%. Our findings revealed that the majority of the study subjects had poor nutritional status, as evidenced by diets lacking in essential micronutrients

Environmental isues of mining activities in Tay Nguyen

Intensive mining activities, specially illegal, negatively affect environment in Tay Nguyen. Mining of gold and tin placers, sand and pebble disturbed the landscape, changed river bed caussing river bank erosion. Exploited wastes from mine, for example, kaolin mine in Loc Chau (Lam Dong province) destroyed and retrograded tea land. There observed evidences of acid mine drainage and pollution of heavy metal including Cu, Pb, Hg, et.c in surface water, stream sediments and soils from some gold mines such as Dak Ripen (Kon Tum), Krong A (Dak Lak) and Tra Nang (Lam Dong). Main causes of mining environmental problems are failure of management, so the first and most important measure of mitigation is to improve the management of mining activities.ReferencesBorisenko A.S., Trần Trọng Hòa, V.I.

Assessment of heavy metal pollution in abandoned Giap Lai pyrite mine (Phu Tho Province)

Giap Lai pyrite mine had been exploited in the period 1975 - 1999, and abandoned after the mine became closed. This work is conducted with the aim to evaluate the impacts of the abandoned mine to the environment. 23 surface water, 15 ground water and 20 soil samples from the mining area were collected for experiments. Acid production potential and metal leaching of waste materials from tailings were tested. Results show that acid rock drainage (ARD) in the old mining area still occurs, with sulfide-rich tailings and waste rocks being sources of ARD, causing elevated metal concentrations in downstream water bodies. Surface water shows significant pollution of Fe, Mn, Ni and partially As. In the rainy season, the percentage of surface water samples having low pH values as well as metal contents in samples is higher than in the dry season. Metal concentrations in ground water are generally low, but many samples have low pH values, indicating the influence of the ARD. The geo-accumulation index reveals that soil from mining area is moderately contaminated with Ni, Cu, Hg and partially As. Most of the polluted samples are located near old mining pits, waste dumps and tailing ponds. The study also shows that negative effect of Giap Lai pyrite mine on the surrounding water and soil has been ongoing. However, no post-closure remediation measures have been applied at the mine, so there must be appropriate solutions for the acid mine drainage treatment before its being discharged to the environment. Given the facts revealed by this study, it is recommended that the Environmental Protection Law should be fully implemented at mining sites not only during the exploitation but also after their closures.References AMIRA, 2002.

Bringing social and cultural considerations into environmental management for vulnerable coastal communities: Responses to environmental change in Xuan Thuy National Park, Nam Dinh Province, Vietnam

This paper elaborates the importance of considering social and cultural factors within management responses to environmental change in coastal areas. The case study taken is Xuan Thuy National Park in Nam Dinh Province, Vietnam. This is a marginalised coastal area where rising sea levels, increasing storm surges and saltwater intrusion place pressure on coastal ecosystems, yet where communities continue to rely on these same ecosystems for agriculture- and aquaculture-related livelihoods. We interview stakeholders in Xuan Thuy National Park, connecting these with a narrative review of existing research into social and environmental change in the park to understand research gaps and challenges for vulnerable coastal areas like the Nam Dinh coast. Based on our findings, we suggest that whilst the effects of a changing environment on physical health and economic activity are increasingly well understood, effects on wellbeing and social relations can be even more immediate and profound in daily living. In turn, we argue environmental management has a crucial role to play not only for ecosystem-based adaptation, but also in sustaining wellbeing and allowing culturally meaningful practices to continue – especially in coastal regions where changes can be even more intense and immediate. However, we caution that whilst techno-scientific solutions grounded in environmental management do have significant potential in reducing impacts of extreme events and slower-onset environmental changes, they must not divert attention away from structural issues that can make some people or areas more vulnerable in the first instance
