Exploring the Iceberg

Why selective adaptive learning meets the needs of students.
GUEST COLUMN | by Jefferson Flanders
My company has employed the metaphor of an iceberg as a way to frame its approach to online adaptive learning for colleges and universities.
The top of the iceberg—the “above-the-waterline” content—includes the core content of a typical introductory college course. Many students will master this content without needing additional instruction. Adaptive learning content is placed “below-the-waterline” and is triggered by diagnostic assessments embedded within the course.
We believe that students will benefit not only from the flexibility and ease-of-use of adaptive learning but also from its selectivity.
The focus is on those common “pain points” where students often encounter learning difficulties. A sophisticated software engine guides students through additional layers of content instruction, which includes games, interactive video, and additional testing.
When we designed the adaptive learning program, we envisioned that this iceberg approach would selectively deliver additional learning content only to those students who needed it. This belief has been validated by the initial responses of students in our Composition One course, an introductory college writing course. Some 60 percent of nearly 7,500 composition students have made use of the adaptive learning feature. Of those students who needed extra help, some 37 percent accessed adaptive learning for one pain point topic, and 50 percent turned to it for two to five pain point topics.
As the following chart demonstrates, many students needed help only on a few pain point topics, but very few accessed all of the 22 that are available (either because they passed the trigger diagnostic assessments or elected not to make use of the additional extra help). Each of the 22 topics points had some students access them, and some triggered more usage than others.
