This unit addressed some important concerns regarding the use of technology in the teaching and learning process. We have learnt the theoretical perspectives of designing an active learning environment that promotes encouraging learning interactions among students. Subsequently, we extended this awareness into the context of instructional technology where we deliberated on several key aspects for effective delivery of instruction, including: learning objectives, learning approaches, students' learning styles and relevant learning resources. In the following section, we explored how technology is rapidly advancing to become a critical face of any teaching and learning process. On this note, we also explored how technology is, and can be, projected into other forms such as computer-managed instruction and computer-assisted instruction that allow us tremendous flexibility to facilitate instructions more effectively. Finally, the unit shed some light on how technology is utilised for teacher training and in the promotion of professional development of teachers.
