Study time 2019

Focused study time
Focused study time

2019 we set a record of the total number of study hours in Cortexio! 182 thousand hours were spent studying, that’s a 48% increase compared to 2018.

A student spends an average of 5min 30s on each chapter and 1min 20s on each question. This is what we call focused study time – which is about 15-20% lower than the total time in the system – since we only measure the time a student is actively studying.

Having good precision in the measurement of the time spend studying is important for the research conducted at Cortexio.
We collaborate with researchers at Linnaeus University and Umeå University to investigate what successful study patterns in Cortexio look like. We collect a big number of data points during a study session: Reading time, time spent on images and videos, text markings and notes made, time spent answering a question and reviewing the answer, etc. In addition, the researchers have access to a cognitive test that a large number of students voluntarily answered, as well as diagnostic knowledge tests.

Hopefully, the research can form the basis for a more adaptive study experience.

For example, the data we collect is used to:

  • Adjust the relationship between reading time and question time based on the individual’s cognitive profile (currently the distribution between reading time and questions is 50/50)
  • Individualize repetition patterns
  • Customize the difficulty of the questions to the user’s level of knowledge

In the spring of 2020 we will work on improving our interface to repeat questions, please come up with suggestions on how you would like it!

Feedback in Cortexio

Each month we receive hundreds of feedback messages concerning improvements on the content in Cortexio. We have a living material and change it according to new best practices and guidelines in the different educations.

On a single month we receive around 400 feedback messages through the Feedback function. The feedback is always read, and we and the different sites on Cortexio try to reply to as much as possible. Thanks everyone for giving feedback!


Failing 15% is the best way to learn

In a new study by Wilson, R.C., Shenhav, A., Straccia, M. et al.  they have found a sweet spot, where the learning is neither too easy nor too difficult. This sweet spot is when the student fails about 15% at the time.

It also ties in to a book we’ve read recently at Cortexio, Hooked by Nir Eyal, where the Hooked model explains how modern software is built to increase user interaction. By giving the user (or student) a variable reward the chances of the user returning to the application is much greater. (This is also why gambling can be such an addiction).

As a teacher it can seem like a daunting job to create individual learning paths for all students where they all have a 85% success rate.

This is why adaptive learning systems like Cortexio are so powerful. Cortexio creates an unique learning path for each student based on their performance where we aim at a 85% success rate.

More about our adaptive learning algorithms will be described in coming posts.
