What is the main feature of Online Courses?

The primary characteristic of online courses is that they offer a diverse array of learning resources and assessments, which can cater to various student needs and learning styles. These courses typically utilize multimedia resources, such as videos, readings, interactive simulations, and forums, allowing students to learn at their own pace and explore subjects more deeply. Additionally, assessments in online courses often include quizzes, projects, and discussions that provide multiple ways for students to demonstrate their understanding.

In contrast, requiring students to attend live classes regularly would limit the flexibility that online courses are meant to provide. Providing hands-on laboratory experiences is generally more characteristic of traditional or blended courses than purely online ones due to the logistical challenges of facilitating such experiences remotely. Focusing exclusively on standardized test preparation also does not encapsulate the broader, more enriching experience typically offered by online courses, which aim to engage students in deeper learning beyond just test-taking skills.
