Book excerpt: The eBook has revolutionized the way students approach mathematics. Each concept is elucidated through videos, which can be accessed by scanning QR codes with a smartphone. This interactive feature brings the learning material to life right on the student’s device. Moreover, the eBook incorporates animated graphs, offering students the opportunity to dissect these graphs frame by frame. This allows them to visually correlate the points on the graph with their algebraic counterparts, enhancing their understanding of the subject matter. The eBook has been well-received by my students, and its format lends itself to be used directly for class presentations by teachers. This dynamic and innovative approach to learning has earned recognition from the Nevada System of Higher Education, which has awarded Professor Du for his pioneering work in this field.
