Blended synchronous learning involves using rich-media technologies to enable remote and face-to-face students to jointly participate in the same live classes. This article presents blended synchronous learning designs from seven case studies that were part of a project funded by the Australian Government Office for Learning and Teaching and articulates principles for implementation as espoused by the teachers who enacted them. A wide range of technologies (including video conferencing, web conferencing and virtual worlds), tasks (namely collaborative evaluation, group questioning, class discussion, problem solving and collaborative design) and levels of student interaction (from lightweight to tightly coupled) were present within the designs. The main issues that teachers confronted when facilitating blended synchronous lessons were those relating to communication and those relating to cognitive overload caused by split attention. Key pedagogical principles for enactment as identified by the lead teachers included the need for extensive preparation, clear instructions, composure, flexibility, advance preparation of students and savvy utilisation of support staff.

This article describes the research design of, and reports selected findings from, a scoping study aimed at examining current and planned applications of 3D immersive virtual worlds at higher education institutions across Australia and New Zealand. The scoping study is the first of its kind in the region, intended to parallel and complement a number of studies conducted in other parts of the world. Results from a sector-wide questionnaire administered as part of the scoping study, portions of which are presented in this article, appear consistent with international trends, especially in terms of the platforms chosen and the dramatic increase in usage seen in recent years. Higher education teaching staff in Australia and New Zealand are using 3D immersive virtual worlds with their students in a variety of ways, for both assessable and non-assessable tasks and in face to face, fully online/distance as well as blended-mode subjects, although use in face to face and blended contexts appears to be most common. The results also provide some insight into the demographics (e.g. age) of staff who have adopted 3D immersive virtual worlds in their teaching, as well as into the academic disciplines in which the technology is being employed.
