An explanatory sketch is a drawing that is used to help explain a concept, process, or idea. It can be used in a variety of situations where visual aids can help convey information more effectively than words alone.
One occasion where an explanatory sketch might be used is in a classroom setting, where a teacher is trying to explain a complex concept to their students. For example, if the teacher is trying to explain the process of photosynthesis, they might draw an explanatory sketch that shows the different parts of a plant cell and how they interact to produce glucose and oxygen.
Another occasion where an explanatory sketch might be used is in a business setting, where a team is trying to brainstorm ideas for a new product or process. An explanatory sketch can help team members visualize how the product or process might work, and can help facilitate discussion and collaboration.
Explanatory sketches can also be used in technical writing, such as in instruction manuals or repair guides. For example, an explanatory sketch might be used to show how to assemble a piece of furniture, or how to troubleshoot a problem with a computer.
Overall, an explanatory sketch is a useful tool for communicating complex ideas in a clear and concise way, and can be used in a wide variety of settings.
