Nguyen Thi Hien, Luu Thi Lan — Fri, 31 Oct 2025 00:00:00 +0700

Innovating teaching methods towards competency-based education is a crucial and urgent requirement to improve training quality and meet the demands of ongoing educational reform. This study focuses on innovating teaching methods for Primary Education students at Hai Phong University. Current practices indicate that many teacher training institutions still rely predominantly on traditional teaching methods, emphasizing written and oral assessments, with limited formative evaluation, practical activities, and experiential learning. Such approaches restrict students’ creativity, critical thinking, and their ability to apply knowledge effectively in real-life contexts. This paper proposes a series of solutions including integrating traditional and modern teaching methods, increasing the use of digital technologies, organizing cooperative group learning, and innovating assessment through continuous evaluation and well-defined criteria for learning outcomes. The study affirms that this comprehensive and synchronized innovation is essential to enhancing the quality of teacher education, equipping Primary Education students with the holistic competencies required to meet professional demands in the context of general education reform.

SOME PEDAGOGICAL APPROACHES FOR IMPROVING THE PRONUNCIATION OF PRESCHOOL CHILDREN AGED 5-6 THROUGH USING LEARNING GAMES

Vu Thi Huong Giang, Pham Thu Thuy — Fri, 31 Oct 2025 00:00:00 +0700

Accurate pronunciation is a key factor in the process of language development, contributing to the formation of effective communication skills and helping children acquire knowledge at the next educational stage. At the age of 5-6, children are at the stage of completing their language development and preparing for entry into primary school. Therefore, the practice of correct pronunciation is not only important for daily communication but also establishes a crucial foundation for learning, particularly reading and writing skills. Based on the psychological and cognitive characteristics of preschool children, this study aims to propose and experiment with several pedagogical measures for pronunciation practice through learning games. This approach aligns with children’s natural tendency to “learn through play,” simultaneously stimulating interest and enabling them to practice pronunciation in a natural, enjoyable, and effective way. Initial experimental results indicate that learning games not only enhance children’s motivation for participate in language activities but also significantly improve the pronunciation abilities of 5- 6-year-olds. The study contributes to affirming the role of integrating games into language education while providing practical implications for preschool teachers in organizing pronunciation practice, thereby improving the quality of school readiness for children before entering primary education.

This study employs the gravity model, panel data set between Vietnam and its main trading partners who are members of CPTPP and EVFTA in the 2010 - 2023 period, OLS estimation technique, STATA software and the stationarity consideration of the panel data, heteroscedasticity, and eliminating multicollinearity using VIF to examine the possible impacts of the CPTPP and EVFTA on international trade and FDI attraction in Vietnam. The estimation results show that CPTPP has an impact on increasing Vietnam’s imports from member countries, but it has no influence on increasing exports and FDI attraction into the country. The estimation results also indicate that EVFTA has no impact on exports, imports, and FDI attraction of Vietnam during the research times as the authors expected. Several policy implications for Vietnam in the coming years are also proposed.

Among these, numerous taxa possess significant ecological roles (wave attenuation, shoreline stabilization, soil amelioration), economic values (timber, tannin, paper pulp, apiculture) and medicinal properties. Several representative species include Sonneratia caseolaris (L.) Engl. , Bruguiera gymnorrhiza (L.) Lam., Kandelia obovata Sheue, H.Y.Liu & J.W.H.Yong, Rhizophora stylosa Griff. and Aegiceras corniculatum (L.) Blanco. These findings reaffirm the crucial role of mangrove vegetation in coastal protection, biodiversity maintenance and sustainable utilization of this natural resource.

THE IMPACT OF CIRCULAR ECONOMY PRACTICES ON THE ENVIRONMENTAL PILLAR OF SUSTAINABLE DEVELOPMENT: EXPERIMENTAL EVIDENCES FROM VIETNAMESE MANUFACTURING SMALL AND MEDIUM-SIZED ENTERPRISES

Nguyen Thi Huong, Le Thi Bich Van — Fri, 31 Oct 2025 00:00:00 +0700

This study employs a multiple linear regression model to examine the relationship between circular economy (CE) practices-based on a five-phase CE framework-and environmental performance (EP), a core pillar of sustainable development, among small and medium-sized enterprises in Vietnam. The results indicate that most CE stages have positive effects on EP, with the exception of the resource extraction stage, which shows no significant impact. Notably, sustainable consumption exerts a negative influence. Capital sufficiency, used as a control variable, also contributes positively. These findings highlight the uneven impact of CE implementation across stages and emphasize the need for more tailored, contextspecific policy strategies for small and medium-sized enterprises in Vietnam.

Nguyen Thi Phuong Loan — Fri, 31 Oct 2025 00:00:00 +0700

The ability to write effectively in English plays an important role in the career development of Vietnamese university students. However, many first-year students often face challenges in generating ideas, organizing their writing, and maintaining motivation. In the context of digital transformation in education, online tools such as Linoit have emerged as promising solutions for enhancing collaborative and interactive learning. This study investigated the application of Linoit in teaching writing skills to first-year students at Hai Phong University as a part of the General English course. A mixed-method approach was employed, including classroom observations, student surveys, teacher interviews, and analysis of students’ written assignments. The findings indicate that Linoit fosters student engagement, encourages idea sharing, and improves the organization of written texts. Students reported increased confidence in their writing and described the learning process as more enjoyable. Nevertheless, challenges such as limited digital literacy and unstable internet connections were also noted. The study concludes that Linoit can be an effective tool for teaching, provides that teachers and students receive adequate training. It recommends integrating digital tools into the formal curriculum of General English course and conducting further research on other AI tools in language learning.

A NEW HYBRID GRADIENT PROJECTION METHOD FOR THE PSEUDOMONOTONE VARIATIONAL INEQUALITY AND FIXED POINT PROBLEM IN BANACH SPACE

Do Duy Thanh, Dang Minh An, Pham Thi Gam — Fri, 31 Oct 2025 00:00:00 +0700

It is known that the variational inequality problem is an extension of the nonlinear compensation problem. It includes convex optimization problems, game theory, Kakutani fixed-point problems, polynomial and tensor variational inequalities, and direct applications in many fields such as operations research, Nash-Counot equilibrium model, and transportation. Methods for solving variational inequalities and fixed points problems have received much attention. However, most of recent methods for solving variational inequalities and fixed points problems require the monotone and Lipschitz continuous or inversestrongly monotone assumptions of the cost mapping. Algorithms are mainly built on finite dimensional spaces or Hilbert spaces. In this paper, we propose a new hybrid gradient projection method to find a common element of the solution set of pseudo-monotone, Lipschitz continuous variational inequality problem with the fixed point set of relatively weak non-expansion mapping in Banach spaces. With the given assumptions, we obtain a strong convergence theorem of the algorithm.
