Various blends of pedagogical strategies and technological affordances have been proposed for the 21st century learners commonly known as the Net Gen, Gen Y, or Digital Natives. At Ngee Ann Polytechnic, we have approached Interactive and Digital Media (IDM) courseware development with a sound learning design that is infused with Learner-Centered-Learning features. This paper reviews the major elements of our journey focusing on the development of learning design leveraging on technology to enhance teaching and learning with a specific focus and application on the teaching & learning of Electrical Technology for the School of Engineering. The paper also describes the courseware, virtual simulation and interactive game developed for this Electrical Technology module.
