What feature distinguishes online learning environments from computer-assisted learning?

The distinguishing feature of online learning environments is their provision for two-way communication. In an online learning setting, students can engage in interactive dialogue with instructors and peers through various platforms such as forums, chats, and video conferencing. This form of communication enables a richer learning experience, where students can ask questions in real-time, contribute to discussions, and receive immediate feedback, fostering a more collaborative and engaging educational atmosphere.

In contrast, computer-assisted learning often relies on pre-packaged software or instructional materials that may not facilitate such interactive communication. While it can involve educational technologies, it typically does not emphasize the active participation and engagement that two-way communication provides. This aspect is key to the social constructivist learning theories that underpin many online education models, emphasizing the importance of collaboration and communication for effective learning.
