Teaching has been the same in many ways for the past 100 years!

I don't have access to TikTok, but the following article challenges the traditional transmission model that is still quite prevalent today: https://educationrickshaw.com/2017/12/02/after-100-years-of-the-same-teaching-model-its-time-to-throw-out-the-playbook/

Students will certainly learn from each other. The question is, what will they learn? The transmission model is seductive because it allows the teacher to ensure that the content meets the the required learning outcomes laid out in the curriculum. Giving students more autonomy may work well for some, but there will also be a lot of cases where students will not engage with the desired content, and will instead find other things to entertain themselves. Keeping students on task is a constant challenge, but with the transmission model there is at least the illusion that students are taking in the required content.
