Knowledge retention and behavior change that impacts outcomes

Qstream uses an interval reinforcement methodology that is scientifically proven to increase knowledge retention by up to 170% and durably change behaviors with measurable impact on outcomes. Co-founder Dr. B. Price Kerfoot is recognized as a spaced education pioneer and has run over 20 rigorous, peer-reviewed clinical trials on Qstream’s technology, proving it works over and over again. Here’s how…

principle 1

The Forgetting Curve

The assumption that if you learn something new it is retained and can be recalled is simply false. Forgetting is a natural, physiological occurrence and must be factored into the sales training process. This phenomenon was documented as early as 1885 when German psychologist Hermann Ebbinghaus published his findings about learning.

The forgetting curve describes the dramatic drop off in knowledge retention over time. Studies show that in as little as 30 days, 79% of knowledge is forgotten. It is simply a matter of how the human brain works.

principle 2

The “Spacing Effect”

Interval reinforcement is a proven way to combat the forgetting curve. The spacing effect explains how you can significantly increase knowledge retention if you present information and reinforce it over spaced intervals of time.

There is a proven neurophysiological basis for the spacing effect. Reinforcement through the application of knowledge over time enhances memory and the survival of new neurons. It increases the efficiency of the uptake of information and encodes the information so that it is preferentially retained.

principle 3

The “Testing Effect”

Testing is not just a dipstick that measures knowledge. Testing, or retrieval practice, is an active learning process that can dramatically improve knowledge retention when combined with immediate answer feedback. This process is known as the testing effect.

Studies comparing the testing effect to passive learning without testing (reading, watching a video) and conceptual mapping (drawing diagrams to relate concepts) show that testing is the most effective approach.

principle 4

Scientifically Proven

More than 20 peer-reviewed clinical trials have been conducted to test the effectiveness of the Qstream methodology. The solution’s underlying approach was initially developed and then rigorously studied by Harvard Medical School Associate Professor, Dr. B. Price Kerfoot, as a “spaced education” method designed to improve the long-term knowledge retention of medical trainees.

These rigorous clinical trials show that Qstream’s approach significantly improves knowledge retention, on-the-job performance, and user engagement.

The interval reinforcement methodology is content-neutral and can be utilized to build knowledge of almost anything. The full multimedia capabilities of the Internet can be harnessed to create rich and effective user experiences.
