+Context: Pilot project
Students said,
“I didn't really find the individual step by step breakdown all that interesting because I seemed to have lost focus of what was going on in the overall picture.”
““it was broken into segments so it was easier to concentrate”.”

We wanted to know
![Page 9: + Effectiveness of segmentation in online learning modules: Are 10-minute modules the best solution? Medbiquitous 2015 So-Young Oh](https://reader034.vdocuments.site/reader034/viewer/2022051401/56649e935503460f94b98b48/html5/thumbnails/9.jpg)
+Research question
Would the segmentation design:
1. facilitate learning?
2. change the acceptability of the web-based learning modules?
3. change learning behavior e.g., time-on-task?

In summary, we learned
![Page 26: + Effectiveness of segmentation in online learning modules: Are 10-minute modules the best solution? Medbiquitous 2015 So-Young Oh](https://reader034.vdocuments.site/reader034/viewer/2022051401/56649e935503460f94b98b48/html5/thumbnails/26.jpg)
+We learned:
A series of mini modules might be as effective as longer modules with “next” buttons
A series of mini modules could be as acceptable as longer modules.
A series of mini modules can be more efficient than one longer module.

+Limitation & Next step: we need to develop
Learning outcomes: different questions?
Particularity of learners
Workflow to integrate the dada analysis into design
More empirical research to support data mining and learning analytics (e.g., longitudinal analysis)
![Page 28: + Effectiveness of segmentation in online learning modules: Are 10-minute modules the best solution? Medbiquitous 2015 So-Young Oh](https://reader034.vdocuments.site/reader034/viewer/2022051401/56649e935503460f94b98b48/html5/thumbnails/28.jpg)
+Significance
Time-on-task is sometimes approached in terms of motivation or engagement: e.g., if students spend more time, this means they are more engaged.
But it is not easy to measure the “engaged” time-on-task. In addition, there are additional factors we should consider: students’ level, difficulty of subject.
Our study shows that time-on-task could be understood in terms of efficiency of learning: if an instructional design allows students to spend less time to learn the same thing (e.g., increase learning efficiency), that design may be a better design
