Some insights into learning in the home n Learning at home allows the students to learn when they want and at their own pace. n Learner can study a wide range of subjects through distance learning at any level. n Learning at home can be ideal if the students are interested in isn't available near where they live, or they prefers the flexibility and freedom of learning in their own time. n The students learn by reading course material, working on course activities, writing assignments and perhaps working with other students. n Learning can be supported by a tutor and the student services. n Learning from home makes use of a variety of media to help with teaching, studying and communication between students and tutors.

T-learning. Role of i. TV within an e. Learning strategy n The term “t-learning” has been adopted as shorthand to mean TV-based interactive learning. T-learning is about having interactive access to video-rich learning materials primarily within the home, through a TV or a device more like a TV than a personal computer. n t-learning is a subset of e. Learning n Learning on-demand n Learner equipment – set top box device (with a network interface, a decoder/synchronization hardware, a buffer, a specialized software – platform, middleware and program software) and display devices

T-learning. Role of i. TV within an e. Learning strategy n Main questions: Ø How to turn a passive viewer into an active learner? Ø How to bridge the gap between “edutainment” and “engaged learning”? Ø How can learning support systems (human and electronic) that help to enable engaged learning be integrated within a TV-based learning environment? Ø What types of interactivity are needed to enhance the learning experience through interactive digital TV?

Digital television Digital TV and STB (with memory storage), remote control, terrestrial, satellite or cable delivery, back channel, remote control or infrared keyboard (optimal) • High quality television picture and CD sound • Program enhancement (forms): picture only, picture with prompt for additional information, picture with overlaid information, information with inserted picture, information only • Data downloading • Multicasting • Near video-on-demand (Vo. D) • Electronic program guides • Internet and electronic mail, etc.

Interactive digital television (i. TV) i. TV is a two-way interactive service provided through television, enabling audiences’ greater choice, control, and customisation over their viewing experience. i. TV services: • Flexible navigation • Video-on-demand • Enhanced television • Interactive program guides • Email and Internet • 3 D works & Multimedia program/channel descriptions • Search functionalities • Personalization and interaction, etc.

Basic models for e. Learning by means of i. TV technology n n ACTIONS model (Tony Bates) Ø Access Ø Cost Ø Teaching and learning Ø Interaction and “user-friendliness” Ø Organizational issues Ø Novelty Ø Speed Channel strategy model (e-Envoy paper)
