Optimise OngoingStoryList / Recommended Stories

[rt4914]

On Home screen there are list of ongoing stories/promoted stories. All these stories are promoted based on two factors:

1. If learner has opened one chapter but has never finished it, in that case that chapter will get promoted.
2. If the learner has finished CHAPTER 1 from STORY 1 then, CHAPTER 2 from STORY 1 will get promoted.

If the learner is completely new then in that case we are showing default recommended stories which promoted Chapter 1 in Fractions as well as Ratios.

So the algorithm TopicListController.createOngoingStoryListFromProgress() can be optimised to keep these story list in timestamp order meaning the recent story should get promoted first.

Pointers on optimising the algorithm:

• Introduce percentage of exploration finished in proto/domain layer and promote the story which is more finished.
• Ordered list via timestamp
• Anything else that you feel can make the user experience better, you can suggest that too.

@BenHenning Partially yes. In optimisation tips there are three points and out of which @veena14cs has to focus on the timestamp part only. The percentage/scoring of exploration is not a part of @veena14cs 's project.
