This is Edgar Dale’s Learning Cone, first developed in the 60’s but reaffirmedby the research and adapted again and again - other derivatives of it are alsoknown as the learning pyramid, or learning triangle. The 'LOTS' stands for 'Lower-Order Thinking Skills' and the 'HOTS' stands for Higher-Order Thinking Skills.' Project-base learning experiences and 21st Century Learning skills lend themselves seamlessly to creating HOTS for our students.


What their research tells us is that on average after two weeks we recall:
  • less than 10% of the content of what we read,
  • about 20% of what we hear, like from a lecture
  • 20 to 30% of content simultaneously using two or more media, like looking at pictures or watching a movie
  • about 30% of lessons involving demonstration
  • about 50% of content that we hear and see like while watching a demonstration that uses two or more media simultaneously
  • 65-80%% of content that involves practice by doing like participating in a discussion or giving a talk
  • and about 90% that involves the teaching of a concept to others as well as the immediate application of the learning within the context of a real time,real world task or a simulation of that task

All of this operates on a continuum from passive receiving of information and traditional learning with a primary focus on LOTS (lower order thinking skills) to active participation and engagement with information, and a focus on HOTS (higher order thinking skills).
