Analyzing Live Interactive Teaching Aids

Let's break down which of the listed tools can be used by a teacher for live interaction in a classroom setting. A live interactive device or teaching aid allows for real-time, two-way communication between the teacher and the students, or among students themselves.

Evaluating Each Teaching Aid

We will examine each option to determine if it qualifies as a live interactive teaching aid:

• a) Email: Email is primarily an asynchronous communication tool. Messages are sent and received, but not in real-time. There is a delay between sending a message and getting a response. Therefore, email is not considered a live interactive device for immediate classroom interaction.
• b) Skype: Skype is a software application that allows users to make voice and video calls over the internet. It supports real-time conversations, including group calls and screen sharing, making it a powerful live interactive teaching aid for virtual classrooms or connecting with remote participants.
• c) On-line Chat: Online chat refers to real-time text-based communication. Platforms like instant messaging applications or chat features within learning management systems allow for immediate text exchange between the teacher and students, or among students. This is a form of live interaction.
• d) Tele-conferencing: Teleconferencing involves the real-time audio and/or video connection of multiple participants in different locations. This is a classic example of a live interactive communication method, often used for virtual meetings, lectures, or discussions in an educational context.
• e) Face-book: While Facebook has features like chat (Messenger) and live video, its primary purpose is social networking. Using the main Facebook platform for teaching often involves posting updates, sharing resources, or conducting discussions which might not always be strictly live or immediately interactive compared to dedicated communication tools. While some features support live interaction, the platform itself isn't solely defined by it as a primary teaching aid.
• f) Blog: A blog is a platform for publishing content, typically in chronological order. Readers can usually leave comments, but the interaction is asynchronous – there is a delay between posting content, receiving comments, and responding. A blog is not a live interactive device.

Identifying the Live Interactive Devices

Based on our evaluation, the tools that support live, real-time interaction suitable for teaching are:

• Skype (b)
• On-line Chat (c)
• Tele-conferencing (d)

These allow for immediate communication, essential for dynamic classroom interactions, asking/answering questions on the spot, and conducting live discussions or lectures.

Conclusion on Live Interactive Teaching Aids

The teaching aids from the list that function as live interactive devices are Skype (b), On-line Chat (c), and Tele-conferencing (d).

Therefore, the correct combination of these options is b), c), and d).

Additional Information on Teaching Technologies

Understanding different types of teaching aids and technologies is crucial for effective online and blended learning. Teaching aids can be broadly classified based on their mode of interaction:

• Synchronous Communication: This involves real-time interaction where participants communicate simultaneously. Examples include live video conferencing, chat rooms, live polls, and virtual classrooms. These tools are great for immediate feedback, discussions, and Q&A sessions.
• Asynchronous Communication: This involves communication where there is a time delay between when a message is sent and when it is received and responded to. Examples include email, discussion forums, blogs, wikis, and pre-recorded video lectures. These tools allow participants to engage at their own pace and schedule.

Both synchronous and asynchronous tools have their place in education, serving different pedagogical purposes. Live interactive devices, as discussed in the question, fall under the synchronous category.
