“Self-Calibration” is now a standard feature on all quizzes

We have just updated Yacapaca with what I think is one of the most profound changes we have made.

It’s called Self-Calibration. Your students will meet it as soon as they start their next quiz. Here’s why and how it works.

Charles Darwin said that “Ignorance more frequently begets confidence than does knowledge”. You probably know students who consistently overestimate their own abilities. It is an emotional defence mechanism known as the Dunning-Kruger effect.¬† Students who over-estimate their own abilities are less likely to study and thus drive themselves into a vicious spiral of failure and denial.

Self-Calibration introduces a gentle but persistent way for students to build and ‘own’ a realistic view of their own abilities. At the start of each quiz, we ask the student to simply¬† “Predict your score”.

At the end of the quiz we assign extra motivation points (that they can spend on new avatars) according to the accuracy of the prediction. Result? Over time, students start to care about self-calibration, and to get better at it.

Self-Calibration appears automatically on all Yacapaca quizzes; you do not need to do anything to enable it. Please do observe it in action, talk to the students about it and give me feedback below on how well it is working.

New: Understand your whole class at a glance with quiz analysis

Being able to see every answer from every student is useful, but sometimes you can’t see the wood for the trees – it’s just too much detail. For a long time, I have wanted to offer key-concept analysis of every assignment, but have stumbled on the problem of finding someone to group our 120,000+ questions into meaningful categories.

Finally, we have a solution. It’s called “crowdsourced analytics”, and I am delighted that we are launching it today. Here’s how it works…

  1. the first teacher to analyse a particular quiz enters their own analysis keywords, and groups the questions under them.
  2. every teacher who assigns that quiz to their own student has the choice of using the existing keywords, or adding their own.
  3. there is a hidden voting mechanism that will promote the most popular keywords so that over time a consensus of the most useful analysis terms will emerge.
