Moderator Sherpa is a new tool that allows users to create moderated apps, assign moderators, and grade apps. It offers different types of questions - objective, subjective, and quick engagement. Users can choose the perfect assignment type, including exercises, problem sets, essays, projects, quizzes, and module exams. Moderators can access all apps and students in one place, dive deep into individual performance, message students, and quickly grade and provide feedback on assignments. Additionally, badges, portfolios, and credentials now have new features like levels, time limits, question banks, and publishing options.
