For years, students have answered the questions at the end of the chapter, relying on in-class grading or odd-numbered answers at the back of the book to find out whether or not they understood the material. At best, students were left with delayed feedback. At worst, they found themselves unequipped for the next test. This year, VitalSource and Wiley have partnered with IMS and the W3C to invent the next release of the ePub for Education standard. Focusing on in-text assessments, this new standard helps to evolve the reading experience. Instead of passively reading a chapter, students will engage with content in new ways, receiving timely feedback on their comprehension of key concepts. The new standard also provides transparency to educators, ultimately informing student success strategies and powering even earlier intervention efforts.
