Attach, Investigate, Explain, Elaborate and Evaluate are stages of:

The Merill Model, also known as the Component Display Theory, is an instructional design framework that consists of five stages: Attach, Investigate, Explain, Elaborate, and Evaluate. Each stage serves a specific purpose in guiding learners through the instructional process:

Key Points

• Attach: In this stage, the learning experience begins by capturing the learners' attention and providing a context for the upcoming content. It aims to create interest and engagement.
• Investigate: Learners are encouraged to explore and gather information related to the topic. This stage promotes active involvement and inquiry, allowing learners to discover and collect relevant data.
• Explain: The instructional content is presented in this stage. Clear explanations, demonstrations, and examples are provided to ensure that learners understand the key concepts and principles.
• Elaborate: Learners are given opportunities to apply and extend their understanding. This stage involves activities that require deeper thinking, problem-solving, and the application of knowledge in different contexts.
• Evaluate: Assessment and feedback mechanisms are integrated to assess learners' comprehension and skills. This stage helps in determining the effectiveness of the instruction and provides feedback for improvement.

Hence, the correct option is 2.
