Dave found KnowItAll Ninja:

• Moderately reduces teacher workload“Videos available for some units reduce own resource creation requirements. Quizzes help reduce test preparation requirements.”
• Does not significantly provide school data“Only internal student monitoring used in class and for individual learning plans.”
• Significantly improves teaching efficiency“Structured to follow the course syllabus so can be matched to scheme of work. Allows students to work at their own pace and for tutors to be better able to provide individual support to the more challenged learners.”
• Slightly improves attainment“Impacts on tutor time and efficiency rather than attainment although attainment may well be a factor for less confident tutors or tutors new to the course.”
• Significantly builds student knowledge“Content is comprehensive and covers all aspects of the syllabus requirements. Can be used standalone for more able students or as enforcement/revision for less able ones.”
