Learning style is a preference for a way of learning matching with an individual’s physical, cognitive, psychological attributes, and learning conditions. Researching on learning styles helps lecturers identify different types of students’ learning styles for selecting teaching strategies to meet students’ learning needs and improve their learning outcomes. The article generates two main research directions on students’ learning styles from document analysis, including (1) Research on students’ learning styles and students’ learning style scales; (2) Studying the impact of learning styles on students’ learning outcomes achievement and teaching strategies of lectures. In addition, the article also identifies gaps in the research on students’ learning styles and proposes in-depth research orientations to meet the requirements of reforming teaching and learning based on developing students’ competence for students using both face-to-face and online teaching methods in higher education institutions in Vietnam. Deploying the proposed research orientations will serve as a scientific basis for adjusting teaching strategies to develop competencies in line with students’ preferences in face-to-face or online teaching modes.
