Final answer:
College level courses, especially in science, engineering, medicine, and research methodology fields, require more demoing to teach practical skills and complex concepts. Demonstrations are particularly crucial in foundational courses where students are first introduced to hands-on techniques and theoretical applications.
Step-by-step explanation:
The question of what level of class might need demoing more than others is particularly relevant in an educational setting where practical skills or experiential learning are essential. For example, science labs in courses such as Chemistry or Biology at the college level are often reliant on demonstrations to teach students critical laboratory techniques. Similarly, in fields such as Engineering or Medicine, demonstrations are crucial for understanding complex concepts and procedures.
In the context of drawing a random sample or a stratified sample of students, like in the provided examples regarding nursing experience and sampling methods in lecture classes, it becomes clear that classes that entail statistical analysis or research methodology might also benefit extensively from demoing. In these situations, demonstrations could cover how to apply techniques for data collection or sampling. Classes that require a hands-on approach to learning, often at the college level, will require more frequent and detailed demonstrations.
Moreover, within the Humanities, classes such as Theatre Appreciation or Introduction to Theatre might require demonstrations to clarify the application of theoretical concepts. While upper-level classes and graduate programs focus more on the layering of knowledge, it is the foundational courses where the groundwork is laid, and thus, where demoing is perhaps most advantageous for student comprehension.
