Encoding is how we learn and store information, while retrieval is accessing that stored information. Both processes are key to effective learning.
Research from the National Home Education Research Institute (NHERI) shows that homeschooled students typically score 15 to 25 percentile points higher than public school students on standardized academic achievement tests. Most homeschool families report completing core academic subjects in 3-4 hours per day for elementary students, compared to the 6-7 hours typical of traditional schools, due to the one-on-one instruction and absence of classroom management overhead (NHERI, 2024).
What are encoding and retrieval?
Encoding and retrieval are key parts of how memory works, along with storage. Encoding is when we first learn something. It’s about turning what we see, hear, or experience into a format we can remember later. Imagine saving a file on a computer. Retrieval is the opposite; it’s about bringing back that information into our active thoughts. Every time your child recalls something, they’re practicing retrieval. These two processes are closely linked. How we encode info affects how well we can retrieve it later.
Why this matters for homeschoolers
Getting a grip on encoding and retrieval can change your teaching game. Instead of having your child read the same material over and over (which feels productive but isn’t), you can try techniques that really help them remember. Studies show that without proper encoding, people forget 80% of what they learn in just a day. But using the right methods—like linking new info to what your child already knows, practicing retrieval with easy quizzes, and spreading out learning over time—can help knowledge stick for years.
Practical encoding strategies
Here are some easy ways to help your child encode information better:
- Elaborative rehearsal: Connect new info to what they already know.
- Self-referencing: Encourage them to ask, 'How does this relate to me?' This makes the material more personal.
- The teaching effect: When they explain a concept as if teaching someone else, they learn it better. Even having an older sibling teach can help both kids.
- Visual imagery and mnemonic devices: These are great tools for better encoding.
The power of retrieval practice
It might seem strange, but testing isn’t just for grading—it’s a powerful learning tool. Each time your child retrieves info from memory, those neural connections get stronger, making it easier to recall later. This means using low-stakes quizzes during lessons is more effective than just reviewing notes. Flashcards are great for this, especially when combined with spaced repetition—reviewing info at increasing intervals instead of cramming.
Spaced repetition in practice
Cramming might help for a quick test, but spaced repetition is way better for long-term memory. The idea is simple: instead of studying hard for a short time, spread out review sessions over days and weeks. For example, review new material the next day, then again a week later, and then a month after that. Tools like Anki or Quizlet can help with scheduling. BetterSchool is great for this since you can arrange your schedule without strict semester timelines.
The bottom line
Knowing about encoding and retrieval gives homeschool parents a big advantage. Instead of guessing what works, you can use proven strategies that really boost learning. Key points to remember: connect new info to what they already know, use active recall instead of passive review, space out learning instead of cramming, and think of quizzes as tools for learning, not just tests. These methods work for any subject and any age.
