If an instructor chooses to customize the course after it has been created, the next page presented will be the Course Content Customization. Here, several choices can be made about the structure of the course, the first being whether to integrate a textbook or not. If a textbook is chosen from the list of available choices using the dropdown menu, ALEKS will automatically place chapter and section references to this textbook on the students' explanation pages.

One choice in the list of textbooks is the ALEKS Curriculum, which is a division of the topics based on the slices of the ALEKS Pie rather than chapters of a textbook. This choice enables student learning to be structured without the use of a specific textbook.
