WGU D664 Learners and Learning Science Objective Assessment | OA 2
Complete Practice Exam: 180 Questions with Detailed Explanations


Section 1: Foundations of Learning Science
Question 1
Which component of the learning process involves transforming sensory input into
a usable form?
A) Storage
B) Retrieval
C) Encoding
D) Feedback
Answer: C
Explanation: Encoding is the process of converting sensory information into a
usable mental form. It is the first step in learning because information must be
processed before it can be stored or retrieved.


Question 2
Which term refers to holding processed information for later use?

,A) Encoding
B) Storage
C) Retrieval
D) Feedback
Answer: B
Explanation: Storage is the process of retaining encoded information over time. It
involves maintaining information in memory for future use. Without storage,
encoding would be meaningless as information could not be retained.


Question 3
What is the process of accessing stored information from memory called?
A) Encoding
B) Storage
C) Retrieval
D) Consolidation
Answer: C
Explanation: Retrieval is the process of accessing and bringing stored information
from memory into conscious awareness. It is the third stage of the memory
process, following encoding and storage.


Question 4
Which of the following is NOT one of the three core processes of memory?
A) Encoding
B) Storage
C) Retrieval
D) Reflection
Answer: D

,Explanation: The three core processes of memory are encoding (transforming
sensory input), storage (retaining information), and retrieval (accessing stored
information). Reflection is not a core memory process.


Question 5
How does cramming affect the cerebrum?
A) Supports strong memory formation
B) Overwhelms the cerebrum, impairing cognitive functions
C) Maximises long-term retention
D) Improves mental organisation
Answer: B
Explanation: Cramming inundates the cerebrum with too much information in a
short period, exceeding its processing capacity. This overload can lead to
confusion, difficulty organising thoughts, and weaker memory retention. More
effective learning occurs with spaced, repeated exposure.


Question 6
Which strategy is being demonstrated when a student studies for 30 minutes each
morning over two weeks instead of cramming the night before an exam?
A) Interleaving
B) Retrieval
C) Encoding
D) Spacing
Answer: D
Explanation: Spacing means spreading learning across multiple study sessions over
time. Studying a little each morning helps the brain consolidate information more
effectively than cramming.

, Question 7
A student alternates between solving algebra, geometry, and trigonometry
problems in a single study session. Which strategy is this an example of?
A) Spacing
B) Interleaving
C) Elaboration
D) Retrieval Practice
Answer: B
Explanation: Interleaving involves mixing different topics or types of problems
during a study session. This helps learners differentiate between concepts and
promotes deeper understanding.


Question 8
A teacher designs a challenging task where students must apply a familiar concept
in a new and slightly difficult way. This strategy is an example of:
A) Spacing
B) Interleaving
C) Desirable Difficulty
D) Metacognition
Answer: C
Explanation: "Desirable difficulty" refers to learning tasks that require effort and
are challenging but not impossible. They enhance long-term learning and
retention by making the learner engage more deeply with the material.


Question 9
What is metacognition?
A) The ability to memorise large amounts of information
B) Thinking about one's own thinking and learning processes
