As increasing numbers of educational institutions implement distance learning (DL) programs, educators need to know how teaching and learning processes change when teachers and learners are no longer in the same place at the same time. Understanding the theoretical and practical implications of these changes can help teachers to compensate learners for the limitations that often characterize a DL environment. In this article, we describe how we used content analysis to identify how university lecturers' verbal and nonverbal dialogue patterns changed when they taught in both conventional and DL environments. Data, indicating significant cross-context changes in teacher-student interaction patterns, validate Moore's (1972, 1993) transactional distance theory. This theory predicts that the increased psychological and communicative space, which needs to be crossed in a DL environment, has a potentially negative effect on teaching and learning. Empirical evidence of changes in specific categories of interaction also expands the conceptualization of the dialogue variable in Moore's theory. The focus of this article on verbal dialogue and nonverbal interactions was intended to clarify possible causes and effects of increased transactional distance in a DL environment. Our integrated analysis of verbal and nonverbal interactions was intended to identify types of compensatory strategies adopted by teachers in an attempt to reduce transactional distance. Teachers could use these results to manage the dialogue variable more effectively in both DL and conventional learning environments.

Although open educational resources (OERs) can help bridge high-school – university vocabulary gaps, optimal utilization of OERs requires effective self-directed learning. This bi-national two-year study adopted a design-based research paradigm to collect Chinese university students' (n = 358) perceptions regarding design factors that support self-directed vocabulary learning in mobile learning environments (MLEs). Results showed that additional scaffolding after Year One in the form of L1 translations of high-frequency academic words significantly correlated with improved performance on basic level vocabulary exercises and pop quizzes. However, results suggest that moving mobile learning into the mainstream will require (1) design features that provide additional scaffolding for more complex vocabulary learning, (2) clearer guidelines for students on integrating desktop and mobile devices and (3) ongoing guidance from teachers to develop students' capacity for self-directed learning to ensure optimal benefit from independent study of vocabulary OERs.
