This study aimed to characterise academics' conceptions of teaching in fully online undergraduate distance education courses with no on-campus component. The study aimed to fill a gap in the literature, as previous research had examined conceptions of teaching in face-to-face courses, with a few studies of blended teaching via the Internet in on-campus courses. Fourteen academics from five faculties in a Vietnamese regional university were interviewed, with the study taking place shortly after the outbreak of Covid-19. Grounded theory was used for data analysis. The results revealed four categories of conceptions of online teaching, namely online teaching (1) as transmitting structured knowledge and skills, (2) as guiding students to acquire knowledge and skills, (3) as facilitating students' understanding via interaction and (4) as developing students' understanding and capabilities. The four categories of conceptions were defined and distinguished by a set of six dimensions, which included e-Learning/LMS. The set of categories had some similarities to those found for face-to-face teaching, but also some distinctions which could be explained by the nature of online teaching and learning. The study, therefore, makes a major contribution by establishing a category scheme for conceptions of teaching in online distance education, with detailed characterisation of the four categories of conceptions. The descriptors of the conceptions showed cultural influences, particularly from a Confucian heritage, which is of significance as research into face-to-face conceptions had not found cultural variations.

Enrolment numbers in online higher education courses have continued to increase over the last decade. The challenges brought about by the COVID-19 pandemic have further accelerated the growth in online and blended course offerings. The development of institutional support services, however, does not reflect this growth. Many students are not equipped with the skills or given adequate support to engage and succeed in their courses, leading to student disengagement and attrition. This study investigated the perceptions of students in online and blended subjects, regarding both the academic and institutional support they were provided. The research team collected interview data from 41 online and blended-learning students and then analysed these data using an iterative thematic analysis approach. This article introduces the key findings with two models: one presenting support strategies at multiple levels within this university; the other presenting three key elements of subject-level teacher support, which were identified by the interviewees as the most significant, effective, and relevant support mechanism in this context. The findings will inform higher education institutions who aim to engage and support online and blended students better, through an improved understanding of how support is perceived by this student cohort. This study was conducted at one Australian university; however, the findings are relevant to higher education institutions in other countries that strive to bring about positive experiences and enhance retention rates for online and blended students.
