Frax limits students to starting one new mission per day so that students can maintain strong focus and attention to the instruction in the activities.

During our student testing with Frax, we found that students began to show focus fatigue as the sessions became longer. They began to make mistakes, experience frustration, and their learning began to regress. By keeping the sessions shorter, students continue to gain understanding and skill with the activities and have a positive experience, so they want to come back for multiple days per week.

While missions are limited to one per day, the student can engage in more usage in The Review Room after all missions are completed in the assigned sector.
