When we first approached Cognella, we did so with previously developed course content that had been in use for more than a decade, but the experts at Cognella took it to a whole new level. The professionalism they added to the textbook was a pleasant surprise, and the addition of the dynamic Active Learning component blew us away. The team worked diligently to develop a slew of interactive games and flashcards. We created video lectures for each topic and developed section-based PPT slides and worksheets. The end product is polished and effective.
