Definition: information that is currently being focused upon
Limited capacity- 5 to 9 bits of information at a time
Expiration: Information is only stored for 15-20 seconds
What does it mean? It is difficult to retain information if there is not time to process and store it.
Working Memory and its Effect on Learning
Students can remember 5 to 9 bits of information at a time.
For example, when learning the Greek alphabet students can remember Alpha, Beta, Gamma, Delta, Epsilon, Zeta, Eta, Theta. They can use repetition or rehearsal to remember the information.
Working Memory and Retention
If information is needed for more than 20 seconds:
Employ maintenance rehearsal and continue repeating information you plan to forget
Employ elaborative rehearsal and connect the new information you are trying to remember with knowledge you already have
Employ chunking by grouping information into logical bits making each bit a new piece of information
Long-Term Memory
Definition: practically unlimited permanent store of information
Requires time and effort to access information
Types of Long-Term Memory
Declarative knowledge: simply knowing that something is the case, (ie. The sky is blue.)
Procedural knowledge: knowing how to do something, (ie. Tying your shoe)
Conditional knowledge: knowing when and why to apply declarative and procedural knowledge (ie. To solve a math problem. You know that 1 + 1=2 but need to use a procedure to determine what the value of x is when 1 + x=2
Working Memory: Storage & Retrieval
Elaboration: connecting existing knowledge with new information
Organization: material that is well organized and structured is easier to remember
Context: it is easier to remember when the current context is the same as the original context (ie. Place, mood, people).
Context serves as a primer to activate retrieval of information.
Long-Term Memory: Retrieval
Spreading activation: retrieval of information based on their relatedness
Reconstruction: recreation of information by using memories, expectations, logic and existing knowledge
