Does "materials" refer to "information"?

Context:

Research has shown that clinicians learn best when we solve clinical problems that mirror real-world situations, get feedback on the choices we've made, and then come to understand when and why we are mistaken. These are “teachable moments,” when — if we're receptive to being corrected — the information we've gained stays where it can be readily retrieved and used as needed. Although it's easy to use online databases to find out more about a disease once you know the diagnosis or more about a particular medicine once you've decided to prescribe it, the process of deciding the best next step for a particular patient in a unique, often complex situation requires an ability to readily retrieve the key pieces of information and apply them to the problem. We thought it might be possible to use software and mobile content delivery to maximize the number and effect of these teachable moments to help clinicians improve their mental flexibility and problem-solving acumen.

With the launch of NEJM Knowledge+, we and the NEJM Group are hoping to help meet the demand for high-quality materials that can augment clinicians' skills and increase their awareness of their own knowledge across the breadth of internal medicine. NEJM Knowledge+ is a self-assessment and improvement program that provides high-quality, clinically relevant content and harnesses key principles of cognitive science to optimize the use of clinicians' valuable time. Designed for internal medicine physicians, subspecialists, fellows, and residents, it comprises more than 1500 clinical vignettes involving conditions that internists should recognize and be able to manage. NEJM Knowledge+ offers a unique way for clinicians to stay current with best practices, improve their care of patients, and use the teachable moments the vignettes provide to develop the self-insight they need in order to grow. In addition, the program is designed to help clinicians meet their certification or recertification requirements. Since the program can run on a desktop computer, an iPhone, or an iPad, clinicians can acquire knowledge in those few moments between patient visits, while waiting in line at a store, or whenever they may have time, whether it's a few minutes or an hour or more.
