An investigation of the academic consulting competence of high school teachers in Vietnam

High school students must grapple with a host of issues and encounter difficulties when studying at schools, such as peer pressure, test anxiety, cyberbullying, unhealthy relationships, psychological distress, depression and possibly domestic issues. These obstacles create the need for academic consulting in order for high school students to develop essential skills and then solve problems. This study aims to examine the high school teachers' perceptions and the quality of academic consulting competence in the Vietnamese educational context. This study surveyed 1089 high school students and 289 teachers in Ha Noi and Ho Chi Minh City in Vietnam with the 43-item questionnaire. The main results showed that academic consulting competence had been noticed and trained professionally for high school teachers. Additionally, both students and high school teachers recognized the essential role of high school teachers' academic consulting competence in educational settings

Using learning games for fourth-grade students to teach Vietnamese lessons and teachers' perspectives on learning games

Students can learn   in   a   meaningful way through the use of educational games. When students apply their skills and information in order to progress through a game, a huge degree of engagement is generated among them in the classroom as a result both their capabilities and their learning   increase. 153 children from primary schools in Vietnam participated in this research. The children were split into two groups: an experimental and a control group. Both groups participated in two sessions of word and sentence practice as well as spelling instruction. According to the findings of the study, the educational outcomes of the students are greatly improved when games are used in their classrooms. In addition, research has shown that some teachers are against the use of games in the classroom since it makes it more difficult to prepare educational materials. Some educators believe that playing educational games is a more effective method of instruction as it allows for greater flexibility during the learning process. This makes a contribution to the theoretical framework that is necessary to guide educators and instructors in the process of improving learning game programs for children in primary schools and other learners

Factors Affecting Consumers’ Intention in Vietnam-China Cross-border E-commerce: An Empirical Study in Hanoi, Vietnam

In the era of innovative technologies, the physical border is no longer a concern in exchanging goods thanks to the widespread use of internet connections. On this basis, the study explores the determinants that impact cross-border online consumers’ purchase intentions in Hanoi, Vietnam. As fundamental ideas, the Theory of Planned Behavior (TPB) and the Technology Acceptance Model (TAM) are integrated with the influence of the Regional Comprehensive Economic Partnership (RCEP). The examined factors consist of Consumer Attitude, Subjective Norms, Perceived Behavioral Control, Perceived Usefulness, Perceived Ease of Use, Perceived Risk, Trust, and RCEP. The research was conducted on a survey questionnaire of 253 online shoppers in Hanoi who have experienced cross-border purchasing. The data was processed using several statistical methods, namely descriptive statistics, exploratory factor analysis (EFA), correlation analysis, and regression analysis. The analysis reveals that Consumer Attitude, Subjective Norms, Perceived Behavioral Control, Perceived Usefulness, Perceived Ease of Use, and Trust have a positive influence on the consumer’s intention to cross-border e-commerce (CBEC), while perceived risk and RCEP do not exert any force on the intention. Among these variables, Risk perception and trust have been demonstrated to have the most significant impact on online purchase intention. The outcomes of the study indicate that online retailers or intermediaries adopt a third-party payment processor and publish policies to protect consumers’ private information. It is also suggested that the government should educate the public on the benefits of RCEP, implement the relevant policies, and provide guidance for the sellers to follow to utilize the advantages of RCEP

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
