Abstract

Competency-based education is becoming increasingly popular in Vietnam, especially in the Mekong Delta region, which is known for its economic challenges and low-lying geography. This approach to education focuses on equipping students with specific skills and knowledge that will enable them to excel in their future careers. However, a study conducted with biology teachers in high schools in the region revealed that although the teachers pay significant attention to developing students’ competencies, such as their understanding of the living world, the results of teaching these competencies are unsatisfactory and require improvement. To improve students’ living world understanding competency, the study recommends that teachers use more experimental teaching methods, including organizing games and role-plays, project-based learning, and research on scientific and technical topics. Additionally, the study suggests that teachers use the STEM and STEAM approaches, which involve integrating different subjects and encouraging creative thinking, problem-solving, and innovation. Implementing these approaches can create a more engaging and interactive learning environment, leading to a better understanding of the living world. The study emphasizes the importance of developing students’ competencies, particularly in low-lying areas like the Mekong Delta, where sustainable development and environmental awareness are critical for the region’s future. Its recommendations offer practical guidance for teachers to enhance their teaching and improve students’ living world competency, contributing to the region’s economic and social development.
