Need Direction on Flashback Project

[subhajitxyz]

Basic Prototype (Not Completed , Ignore the toolbar text Concept Card. It should be Flashback Card)

Record_2025-03-16-09-26-29_943a62cb4c6fb83e010e1c2e82766a17.mp4

In video some basic feature is missing like - (A dialog pops up inviting them to review a previous concept . The learner can accept or cancel.) and (showing learn again section in "Previous responses" section after seeing the solution and return back to the pending question)

What have i done here?

To show Learn Again button (implemented in this PR #5626 in similar way)

1. Added a new state, CompletedState need_to_revisit_old_card, in EphemeralState (a state where the "Learn Again" button will be shown).
2. Added a string field, previous_state_name, in AnswerOutcome (indicating that the learner should move to one of the previous states for revision).

To show the Flashback Fragment

1. StateFragmentPresenter

fun onLearnAgainButtonClicked() {
    if(stateViewModel.getFlashbackIsOn()) {

      flashbackCardListener.routeToFlashBackCard(
        this.explorationId,
        ephemeralState = explorationProgressController.getFlashbackEphemeralState()
      )
    }
  }

2. ExplorationActivity

override fun routeToFlashBackCard(id: String, ephemeralState: EphemeralState) {
    if (getFlashbackCard() == null) {
      val flashbackCardFragment = FlashbackCardFragment.newInstance(
        id,
        writtenTranslationContext,
        ephemeralState
      )
      flashbackCardFragment.showNow(supportFragmentManager, TAG_FLASHBACK_CARD)
  
    }
  }

I have some doubt about this section (taken from Flashback Project Description)

Additionally, this project also includes improving the general look-and-feel of submitted answers for both multiple choice and item selection interactions as these both currently rely on HTML generation rather than having a cleaner, natively rendered experience. This change will also allow them to be displayed properly in the 'flashback' experience.

1. Do we want to show the previous question and its correct answer, together with a solution explanation in Flashback Card? (like given in figma design)

2. Does our current Assest support showing previous question answer on stuck state?

Hi @BenHenning , @seanlip , @adhiamboperes , I need some clarification on the above questions and want to ensure that I am heading in the right direction.

[subhajitxyz]

But I think the project description is all about Option 1. (Correct me if I'm wrong.)

[seanlip]

It isn't, but on reading it again, I can see some parts that could perhaps be clarified. The "reviewing an earlier concept" doesn't mean looking at the concept card, it means looking at a question that teaches that concept. Was it that part that was confusing, or are there other parts of the project description that would be helpful to clarify?

[subhajitxyz]

Thanks @seanlip , you are right. that was the part and the milestone part was also bit confusing for me.

My current understanding is that:

1. We are trying to show a flashcard when the user submits a wrong answer and gets stuck.

2. The flashcard will display the previous question and its correct answer, which are related to the user's misconceptions.

Now, I have some questions:

1. Does the current asset contain this data? (Meaning, when a wrong answer is submitted, can we directly retrieve the question and answer to show in the flashcard?)

2. Or do we need to dynamically determine which question and answer should be displayed on the flashcard?

[BenHenning]

We need to dynamically determine the question and answer by inspecting the StateGraph from when the user most recently visited the state being reviewed (which we know from the Outcome of the answer that triggers the flashback state), and copying the question and correct answer to show in a temporary new mode of EphemeralState. This new EphemeralState would only stay in the StateGraph for as long as the review is being reviewed. We need to inspect the most recent visit (by state name) in the state graph, and copy the correct answer (always the last one in the list).

Thanks @BenHenning .

Hi @BenHenning , @seanlip ,

I have question related Flashback project.

1. Do I need to introduce a feature flag for this project?
2. Is it necessary to use the exact milestone descriptions from the project document as deliverables in the proposal (Milestone Table)?

Some question related milestone description.

1. What does "existing softer redirection button" mean here?
2. What does "in-line view" refer to?

[adhiamboperes]

@subhajitxyz, please see What we are looking for in proposals in the GSoC wiki. It specifies:

An explanation for how the new functionality will be gated behind a feature flag to ensure that changes don't get shipped to end users before the feature is completed.

For:

Is it necessary to use the exact milestone descriptions from the project document as deliverables in the proposal (Milestone Table)?

It is possible to paraphrase, so long as the expected deliverables are all covered.

For:

What does "existing softer redirection button" mean here?

It refers to the button introduced in #5626

Hi @adhiamboperes , Can i break down Milestone points in multiple PRs ?

[adhiamboperes]

Yes you can. PRs usually need to be as small as possible to make review easier.
