Onlea was an essential partner in the development of our online course Astro 101: Black Holes. Onlea created fantastic visuals that allow our learners to comprehend concepts that might otherwise be inaccessible. Working with Onlea was fun - they helped us explore different ways to present the material so that our learners can both understand and enjoy the concepts. One of my personal goals when developing this course was to create a course that would be fun for our learners, as well as employing sound educational methods. Onlea played a key role that helped us reach this goal.
