Blended teaching has recently attracted a lot of attention from educators and researchers worldwide. In Vietnam, blended teaching has been applied at various universities in different forms. However, few studies have been conducted to explore EFL teachers’ perceptions of the use of blended teaching in Vietnam. The current study used a questionnaire to explore the perceptions of thirty EFL teachers from a large university in Vietnam.

This paper deals with clustering of periodic orbits of the hyperbolic toral automorphism induced by matrix A. We prove that Ta satisfies the Axiom A. The clustering of periodic orbits of Ta is ivestigated via the notion of 'p-closeness' of periodic sequences of the respective symbolic dynamical system. We also provide the number of clusters of periodic sequences with given periods in the case of 2-closeness.

While blended teaching is increasingly becoming popular in higher education all over the world, the concept has recently been paid attention to in Vietnam’s context. However, under the impact of the COVID-19 pandemic online teaching and blended teaching suddenly become a popular trend in Vietnamese higher education. Few studies have been conducted to explore topics related to blended learning in Vietnam and the current study was conducted to fill such a gap. This study focuses on exploring English-majored students’ perceptions toward the benefits and challenges of blended leaching in EFL classes. Participants included 440 English-majored students ranging from 18 to 22 years old coming from three study majors namely English Teacher Education, English Language Studies and English Interpretation and Translation in a multi-disciplinary university of 56 years old in Vietnam. Findings reveal that students perceived that blended learning offers them various benefits as well as some challenges. Suggestions are proposed to enhance blended learning for English-majored students in Vietnam and elsewhere.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0939/a.php" alt="Hit counter" /></p>
