Cengage offers online versions of the books they publish through their platform MindTap. It's used by students and instructors to read course books and submit/grade quizzes and assignments. Through the 'adaptive Mindapp' this process was made adaptive leveraging another service offered my 'Knewton API'. This means that instructors don't need to assign reading materials to students and attach quizzes or assignments to a chapter. Now they just need to add a chapter or a group of chapters as 'Study Centers' and app will do the rest i.e. assess student's performance based on the assessment/graded activities and assign instruction/reading/ungraded activities to student where he/she is felt to be lacking in confidence. Instructors can also add a proficiency to this study center which signifies how much proficient he wants the students to be in the corresponding concepts which can be seen through a 'proficiency report'.
