The development phase is where the instructional design plan starts taking shape. In this stage, all the materials and activities needed for learning are created and assembled. For instance, if the goal is to improve problem-solving skills in agriculture students, developers might design interactive simulations, real-world case studies, and group project guidelines.

Key tasks during this phase include writing detailed lesson plans, creating visuals like graphics and diagrams to enhance understanding, and developing digital tools such as eLearning modules or videos. Practice exercises and feedback systems are also built to help learners achieve their objectives. Additionally, prototypes of the materials are tested to ensure they work well and align with the learning goals.

This phase involves teamwork among instructional designers, subject matter experts, graphic designers, and programmers to ensure the content is engaging, effective, and meets the needs of learners.
