This course includes many interactive opportunities where students can strengthen their knowledge and practice using the concepts taught in the course. Research has shown that this type of learn-by-doing approach has a significant positive impact on learning. Interactive opportunities come in multiple forms:
Practice questions appear on most pages in the course, embedded in the main text of the page. The purpose of these questions is different than questions on self-checks or quizzes, which are designed to see if the student has mastered the concept. Instead, practice questions allow students to learn by interacting with the concepts they are learning about. For example, a practice question might present a student with a scenario and ask them to apply the concept that they have just read about.
These practice questions do not count for a grade, and getting the answer “wrong” can be just as valuable to the learning process as answering correctly, as practice questions often address common student misconceptions and give students immediate feedback intended to correct those misconceptions.
Additionally, there are dedicated practice pages provided for learning outcomes that are particularly challenging. The problems on these pages are algorithmically generated, and thus allow students to practice as many times as they need to.
