This comprehensive practice examination is designed for students preparing for
the WGU D664 Learners and Learning Science Objective Assessment. It serves as
a complete study guide and exam review, reflecting the latest update for
2026/2027. The questions are meticulously crafted to mirror the difficulty,
scenario-based style, and scope of the assessment, covering all essential domains
including foundational learning theories, cognitive processes and memory,
developmental theories (Piaget and Erikson), neuroscience foundations,
motivation and self-regulated learning, instructional design and assessment, and
diversity, equity, and inclusion. By engaging with these practice questions and
answers, candidates can assess readiness, identify knowledge gaps, and reinforce
critical learning science concepts. The detailed rationales provide verified
solutions, ensuring deep comprehension and enhancing preparation for this
competency-based assessment.

Question 1: A high school biology teacher explains to students that the brain is
not like a computer because it constantly changes and adapts based on experience.
Which neuroscience concept is the teacher emphasizing?
A) Synaptic pruning
B) Neuroplasticity
C) Myelination
D) Lateralization
Correct Answer: B
Neuroplasticity refers to the brain's ability to reorganize itself by forming new
neural connections throughout life in response to learning, experience, and
environmental changes. This directly contradicts the brain-computer analogy,
which suggests a fixed, hardware-like structure. Understanding neuroplasticity
empowers students and teachers to view intelligence and ability as malleable
rather than fixed, fostering a growth mindset and resilience in learning.
Question 2: A teacher notices that students who review vocabulary words for 15
minutes every day for two weeks perform significantly better on the unit test than
students who cram for two hours the night before. Which learning science principle
best explains this outcome?
A) Massed practice
B) Spaced practice
C) Rote memorization
D) Dual coding
Correct Answer: B
Spaced practice (distributed practice) involves spreading study sessions over time
, 3
rather than concentrating them into a single session. This leverages the spacing
effect, which strengthens memory consolidation by allowing time for forgetting and
subsequent retrieval, thereby deepening neural pathways. Research consistently
demonstrates that spaced practice produces more durable, long-term learning than
massed practice (cramming), which typically yields only short-term retention that
rapidly decays.
Question 3: A middle school teacher asks students to answer practice questions
from previous units before introducing new content. According to learning science
research, which memory process is this strategy primarily strengthening?
A) Encoding
B) Storage
C) Retrieval
D) Sensory registration
Correct Answer: C
Retrieval practice involves actively recalling information from memory, which
strengthens the neural pathways associated with that information and makes future
retrieval easier. This process transforms learning from passive review into active
reconstruction, enhancing long-term retention more effectively than re-reading or
highlighting. Each successful retrieval act subtly modifies the memory trace,
making it more accessible and durable over time.
Question 4: A teacher is designing a lesson on the American Revolution and
alternates between teaching about causes, key battles, and political outcomes rather
, 4
than covering each topic in a single block. Which evidence-based learning strategy
is the teacher using?
A) Blocking
B) Interleaving
C) Elaboration
D) Chunking
Correct Answer: B
Interleaving involves mixing different topics, concepts, or problem types within a
study session rather than grouping similar items together (blocking). This strategy
improves discrimination between concepts, enhances long-term retention, and
promotes deeper conceptual understanding by requiring the brain to constantly
switch between retrieval pathways. While interleaving may feel more difficult
during learning, it produces superior performance on delayed tests compared to
blocked practice.
Question 5: A teacher explains to colleagues that students cannot truly multitask
during online learning because the brain switches rapidly between tasks rather than
processing them simultaneously. Which brain structure's limitations support this
explanation?
A) The cerebellum
B) The brainstem
C) The prefrontal cortex
D) The limbic system
Correct Answer: C
The prefrontal cortex is responsible for higher-level thinking, including attention,
