Volume 1: Theory, Concepts, and Applications. Toward Thinking Like a Nurse. Theories on learning have shown that students learn better if they can see how the content will be useful to them. They understand better when presented with something concrete in addition to tackling the abstract definitions and theory. Volume 1 emphasizes the relationship between theoretical knowledge and practical knowledge to encourage each of your students to think like a nurse. This approach allows you to emphasize either theory or practice as it suits you and your students.
