This will be a randomized controlled trial in which eligible participants will be members of the general surgery residency and adult gastroenterology fellowship. Investigators will ask all consenting participants to fill out a baseline set of demographic information including their year of training, the approximate number of colonoscopies to date, specialty, age, sex and dominant-handedness. Additional questions to be asked will inquire about the participant's experience in regard to the unassisted and supervision/coached colonoscopy module experience. Participation in this activity is completely voluntary, and the participating trainee is under no obligation to complete or finish the simulation or subsequent surveys The participant will be randomized to one of two groups. A computer program will make this random assignment. Neither the participant nor their physician coach will be able to choose which group they will be in. Participants will either first partake in an unassisted colonoscopy module twice (case one and case two) and then transition to a supervised/coached colonoscopy module session twice (case three and case four). The alternative is in which the participant first partakes in a supervised/coached colonoscopy module session twice (case one and case two) and then transitions to performing an unassisted colonoscopy module twice (case three and case four). A questionnaire examining training experience will be administered after case # 4 in both groups. This survey will take approximately 5 minutes to complete. Other objective measures will be assessed by supervising faculty and other metrics acquired through the simulator software. Individuals' survey responses will be used to see if early supervision improves trainee satisfaction and perceptions on survey scores. Participants will attend one individual training session date that will satisfy the designed simulation experience. The trainee can stop participating in this study at any time and participation in the study is voluntary and trainees may choose not to participate. It is important to note that refusal to participate will not affect a learner's access to the training center and will not affect their standing in their respective training program. The results will not be included in their official training record. Note no prior procedural or technical knowledge is required. Enrollment will continue for the 2018-2019 academic year and possibly academic years thereafter.
