Certainty Based Marking (CBM), or more conveniently Confidence Based Marking, fascinated me while I was studying education. Therefore, it was only a matter of time when this super useful concept would also find its way into our app chunkx. CBM and adaptive learning are a great fit.
What Is Certainty Based Marking?
In chunkx, microlearning content is often supplemented by interactive learning tasks. This allows us to learn more about the individual user's knowledge and non-knowledge, and to prioritize and, if necessary, repeat content accordingly. Learning tasks in the form of single choice or multiple choice, however, have the disadvantage that simple guesses are quickly made. That's where CBM comes in:
Certainty Based Marking asks users not only to answer an objective question, but also how certain they are that their answer is correct. Our scoring system particularly rewards not only selecting the correct answer, but also being maximally confident in doing so. Certainty Based Marking encourages reflection on how sound one's knowledge and skills really are.
| Answer | Stated confidence | Scoring |
|---|---|---|
| Correct | High | Highest score – sound, confident knowledge |
| Correct | Low | Few points – correct, but still uncertain |
| Incorrect | Low | Little penalty – the uncertainty was honest |
| Incorrect | High | Strongest penalty – a dangerous misconception that needs addressing |
How Is CBM Used in chunkx?
chunkx is a microlearning app that adaptively selects learning content — individually and suited to each user. CBM makes a lot of sense in this context: the self-assessment of certainty helps to better classify one's own level of knowledge. And our algorithms use this classification to decide which content to display next that is most appropriate for the user.
Must CBM Always Be Used in chunkx?
Authors use the chunkx creator to create channels and microlearning content. CBM can be used for all content with closed tasks — completely optional as a checkbox that can be quickly turned on and off. By default, it is enabled because we are convinced of the concept and the user experience is significantly improved both in terms of response and more appropriate content selection.
Adaptive Learning with chunkx
With chunkx, we offer a tool to expand both new and existing learning measures in a targeted manner. chunkx is aimed at both companies and educational institutions such as universities or schools. In addition to closed instances, chunkx offers a public area where academies such as those offered by Gemeinsam-gegen-Doping, the Lehmbruck Museum, and other educational institutions are available.
