1. Teaching methods for addition have changed, using blocks instead of the traditional algorithm, but the research supporting this change was questionable.
2. Ineffective teaching methods that are intuitive can be appealing but ultimately wrong. Education requires constant renewal of our understanding to avoid falling into these traps.
3. Teachers often face challenges when trying to implement research-backed teaching methods, and the education system can be susceptible to ineffective professional development.
4. Marking homework twice a week does not have a significant impact on student learning.
5. Children should not default to working in groups, and individual roles and columns in classrooms can create focus.
6. Teaching kids should be done by kids themselves, possibly by hiring them as teachers.
7. Mobile phones have no place in schools and stricter policies should be enforced.
8. Teaching students the habit of being offline allows for better focus and prevents constant online presence.
9. Having high expectations for students is important, but proper instruction and support are also necessary for learning.
