It’s the 21st century where everything is fast: Technology, information, economy, lifestyle, etc. – who is in his right mind advocate for “Slow Education”?
Well, Slow Education is not synonymous with slow learning. The term “Slow Education” emerged from the “Slow Food Movement” which is basically the opposite of “fast food”. It is based on the principle of promoting sustainable high-quality local and health products which is ecologically sustainable and ethical. The use of “slow” has nothing to do with speed, it means more time for discussion, reflection and learning in-depth.
The idea of slow education is to cut down curriculum content and focus only on what is essential. A combination of didactic and authentic pedagogies is still in place, but the topics are divided into bite-sized chunks and learners are given the time to process. The philosophy of Slow Education is to give a rich, active experience that is not rushed. It provides for a learning environment where learners can discuss, argue, learn from the ideas of others and have quality interactions with teachers and other learners.
But how will learners adapt to the fast-paced demand of the time? Slow education learners are trained to understand basic concepts and how they are applied, thus, they will learn very quickly. When learners can focus on one topic at a time, understanding and retention are better. On the other hand, the traditional educational systems cram the syllabuses with massive content so that students can accomplish them in a short amount of time. This is counterproductive because learners will be overwhelmed that they forget much of the content they learned or memorized.
Slow education is very promising because it theoretically raises the educational value of learners. Learners are more inspired to learn because they are nurtured to understand in depth. They can think critically rather than blindly believe in their teachers with radical agendas. The stress and anxiety associated with fulfilling a lot of subject requirements decline.
It is worth noting that few schools embraced the concept of slow education, like Eton, Matthew Moss High School, Blue Gum Community School and others. Only time will tell if these schools will succeed considering the lack of government support for this initiative.
