Which of the following is an example of direct instruction strategy?

Direct instruction is a teaching approach characterized by structured lessons that focus on explicit teaching of concepts, skills, and knowledge. Demonstrations are a prime example of this strategy because they involve the teacher showing students how to perform a task or understand a concept in a clear and straightforward manner. This hands-on method allows students to visualize the process and can include step-by-step guidance, making it easier for them to grasp complex ideas or skills effectively.

In contrast, the other options rely more on student exploration and discovery or involve less direct teaching. Problem-solving often encourages students to work through challenges independently or in groups. Case studies typically ask students to analyze real-world scenarios, fostering critical thinking rather than direct instruction. Inquiry-based learning involves students posing questions and investigating answers on their own, which is more open-ended and explorative compared to the structured nature of direct instruction.
