Which of the following is a key advantage of the ISD approach?

The key advantage of the ISD (Instructional Systems Design) approach is the efficient design of training courses. This methodology is systematic and emphasizes a detailed planning process that ensures the training is not only effective but also conducted in a streamlined manner. By assessing the needs of learners, defining clear objectives, and creating content that aligns with those objectives, ISD helps ensure that resources are used optimally. This efficiency leads to well-structured courses that enhance the learning experience and increase the likelihood of achieving desired outcomes.

Other strategies, such as focusing on group learning, utilizing multimedia resources, or emphasizing social interactions, may enhance particular aspects of training but do not encapsulate the essence of the ISD approach, which is primarily centered around the effectiveness and efficiency of the overall instructional design process.
