,Section A - Learning
Q1.
In a complex problem-solving task, learners who verbalize their reasoning while working
show improved performance compared to silent peers. This phenomenon is best
explained by which theoretical construct?
A. Cognitive load theory's intrinsic load B. The self-explanation effect and its
reduction facilitation of deep processing
C. Social constructivism's zone of proximal D. Dual coding theory's visual-verbal
development integration
Correct: B - The self-explanation effect and its facilitation of deep processing
Rationale:The self-explanation effect occurs when learners generate explanations to
themselves, promoting deeper cognitive processing and integration of new knowledge. It is
distinct from social constructivism (which involves interaction with others) and cognitive load
theory (which focuses on load management). Dual coding involves verbal and visual channels
but not self-generated reasoning.
Q2.
A curriculum designer plans to teach a complex concept. To optimize learning, they first
present simplified examples and then gradually introduce complexity. This instructional
sequence aligns most directly with which theory?
A. Elaboration theory's progressive B. Spaced practice's interleaving principle
sequencing
C. Transformative learning's perspective D. Operant conditioning's shaping procedure
transformation
Correct: A - Elaboration theory's progressive sequencing
Rationale:Elaboration theory emphasizes organizing instruction from simple to complex,
building on a basic epitome and elaborating with increasing detail. Spaced practice involves
time intervals, not complexity sequencing. Transformative learning is about critical reflection
and perspective change. Shaping involves reinforcing successive approximations, but not
necessarily in instructional design for conceptual understanding.
Q3.
A study finds that students who generate their own test questions perform better on a
final exam than students who review provided questions. This advantage is best attributed
to which cognitive principle?
Page 3
, Section A - Learning
A. The testing effect, which enhances B. Generation effect, which enhances
retrieval practice memory through self-production
C. Elaborative interrogation, which prompts D. Metacognitive monitoring, which
relational reasoning improves calibration of understanding
Correct: B - Generation effect, which enhances memory through self-production
Rationale:The generation effect refers to improved memory for information that is
self-generated rather than passively received. Generating test questions requires active
engagement and deeper semantic processing, leading to better retention. The testing effect is
about retrieval practice, but the advantage here is specifically due to generation, not retrieval.
Elaborative interrogation involves asking 'why' questions, and metacognitive monitoring is
about self-awareness, not the act of generation itself.
Q4.
When designing a multimedia lesson, including a short animation with simultaneous
narration is more effective than including the same animation with on-screen text. This
finding is directly predicted by which principle?
A. The redundancy principle, which states B. The modality principle, which states that
that redundant on-screen text can overload visual and auditory channels should be used
the visual channel simultaneously
C. The signaling principle, which states that D. The personalization principle, which
cues should highlight essential material states that conversational style enhances
learning
Correct: B - The modality principle, which states that visual and auditory channels should
be used simultaneously
Rationale:The modality principle (Mayer) states that learners learn better from animation and
narration than from animation and on-screen text because narration uses the auditory
channel, freeing the visual channel to process the animation. The redundancy principle
actually warns against presenting the same information in both text and narration. Signaling
and personalization are different principles.
Q5.
A teacher uses a classroom response system where students answer a question
individually, then discuss in small groups, and then answer again. The improvement in
scores after discussion is most directly explained by which concept?
A. Peer instruction, which leverages social B. Formative assessment, which provides
construction of knowledge immediate feedback to the teacher
C. Collaborative learning, which distributes D. The testing effect, which strengthens
cognitive load among members memory through repeated retrieval
