I agree passionately with you on many of the points you shared. Kids should have more freedom to pursue their interests in school, more opportunities to collaborate with others, and more chances to get up, move and not stay in their chairs all day.
The problem that I see is that kids will completely neglect to learn anything that they don’t see relevant today. Take learning about percentages. I doubt a kid would trip into learning about what a percentage is, and yet, it is valuable going forward to know how much they might save at a 25% off sale.
History also needs to be taught, because we might not learn from our mistakes of the past unless we learn what those are. But I agree, kids don’t need to memorize the names and dates of World War 2- it would be more valuable to have an assignment on why the German people followed Hitler, even when they learned what he was doing.
There needs to be a balance between learning what you love, and learning things that may be relevant in the future.
But yes, more projects, more fun, and more student directed learning could be a huge improvement at schools.
