The interaction between a learner and the learning environment is a critical determinant in the success of the individual. The more engaged, connected, and communicative the student is within the learning environment, the greater the opportunity for success. Interactions become even more challenging when the learning environment is online, where the opportunities for communication and psychological distance increase, leading to a sense of isolation. Dr. Alex Casteel is dedicated to researching and implementing successful programs for learner success within online environments through analysis of the environment, examination of behaviors within the environment, and measurement of learner performance in order to maximize student retention and to enhance learner performance.
