1. Retrieval practice is an incredibly powerful strategy in which students actively draw out previously-taught knowledge from their brains, thus enhancing "diverse forms of learning, including memory, problem-solving, and generalization to new situations." When we challenge students to frequently and intentionally retrieve knowledge, they grow in their abilities to retain and quickly access information. We believe that both retention and quick retrieval are essential foundations for students when it comes to "deeper learning" and transferring skills and conventions to different contexts. Traditionally, quizzes and tests are used in the classroom as a form of retrieval practice. At Podsie, we combine the research-backed power of frequent, low-stakes retrieval practice with spacing and interleaving to enhance the learning of students.

2. Spacing gives students an opportunity to practice the skills, conventions, and strategies that a teacher has already finished teaching in a way that is aligned with cognitive science research. Our spacing algorithm ensures that students are practicing previously-taught standards based on:
                1. their demonstrated mastery of the standards
               2. specific time intervals that enhance their retention of the standard
               3. the concepts that students find more challenging to retrieve will show up first, and more                      frequently.

3. Interleaving is accomplished by allowing students to practice multiple previously-taught standards that are interleaved with more recent standards.

Differentiation is accomplished through personal decks, which are uniquely tailored to each individual student. Whenever a teacher assigns a class or group of students a set of practice questions, these questions are fed into their personal decks, and our spacing algorithm does the work to ensure students are retrieving the knowledge that they, as individual learners, need to practice the most. We understand both the need and the impossibility of creating 100+ assignments for each unique learner that a teacher has in their classroom. Podsie has differentiation covered.
