Which step of the Four-Step Development Model evaluates the effectiveness of a course?

The correct answer is C, which pertains to the evaluation step of the Four-Step Development Model. In this context, the evaluation step is crucial as it focuses on measuring the effectiveness and outcomes of the course after it has been implemented. This involves assessing whether the learning objectives have been met and determining how well the training has prepared the participants to perform their roles effectively.

During the evaluation phase, various methods may be employed, such as feedback forms, assessments, or performance observations, to gather data on participants' learning and application of the material. This feedback not only helps in understanding the impact of the training but also identifies areas for improvement in future iterations of the course.

The other steps, while important within the model, serve distinct purposes. The design phase is where the course framework and content are created, ensuring that the learning objectives align with the needs of the participants. The implementation phase involves conducting the training, facilitating the delivery of the content to learners. Assessing, although related to evaluating, typically refers more to the process of measuring knowledge or skills gained during the instruction, rather than evaluating the overall course effectiveness.
