Personal Deck

The Personal Deck is Podsie's most important feature. Here's how it works:

1. Each student has their own Personal Deck.
2. When students complete an assignment, by default, all the questions from that assignment are inserted into their Personal Deck.
3. Then, based on how students previously performed on each question, the Personal Deck will determine when the student needs to review that question again.
4. As a result, each student will get a personalized review experience based on their prior performance.

1. Let's say that a teacher assigns an assignment that has two questions: the first question is on simplifying fractions, and the second question is on one-step equations.
2. When a student completes that assignment, both questions will go into that student's Personal Deck. Both of those questions will be "due" at a future date. How soon a question shows up again is determined by each student's prior performance on that question.
3. So, let's say that John struggled with the question on simplifying fractions, while acing the question on one-step equations. In this case, the question on simplifying fractions will show up earlier in the Personal Deck (in about 1 day). Meanwhile, the question on solving one-step equations would show up later (in about 1 week).
4. If a student consistently gets a question correct, then the question will get scheduled for review at an increasingly later date. For example, let's say that a week later, the question on solving one-step equations (which John previously got correct) shows up, and he gets it correct again. When he got it correct the first time, he saw it about 1 week later. Now that he got correct a second time in a row, he would see it at an even later date (about 3 weeks later). If he gets it correct a third time in a row, then the next review would be scheduled at an even later date (about 2 months).

In summary, Podsie uses an expanding interval scheduling algorithm, which visually looks like:

Over time, each student will end up reviewing the questions that they most need to review at that moment.

Whenever a student starts studying their Personal Decks, they start a Personal Deck Study Session:

By default, a Study Session is a maximum of 20 questions. In the example above, there are 32 questions currently due in the personal deck. If a student starts a Study Session, then only the first 20 questions will be pulled into the session:

In this case, the student would not see the other remaining 12 questions until the student is done with the 20 questions in the current Study Session.
