,Section A - Learning
Q1.
A curriculum designer is creating a lesson on climate change. Which approach best
reflects the principles of constructivism?
A. Providing a detailed lecture with diagrams B. Having learners engage in a simulation
and charts to ensure accurate transmission where they manipulate variables and reflect
of facts on outcomes
C. Drilling key terms and definitions through D. Showing a documentary followed by a
flashcards to build automaticity multiple-choice quiz to assess
comprehension
Correct: B - Having learners engage in a simulation where they manipulate variables and
reflect on outcomes
Rationale:Constructivism emphasizes active knowledge construction through experience and
reflection. A simulation allows learners to explore and build understanding, whereas lectures,
drilling, and passive viewing align more with direct instruction or behaviorism.
Q2.
Which scenario best exemplifies the testing effect, and why is it beneficial for long-term
retention?
A. A student rereads textbook chapters B. A student practices retrieval with
multiple times before an exam, reinforcing self-quizzing, strengthening memory traces
familiarity. through effortful recall.
C. A student creates concept maps to D. A student studies in a group, discussing
visually organize information, integrating ideas to deepen understanding through
new knowledge. social interaction.
Correct: B - A student practices retrieval with self-quizzing, strengthening memory traces
through effortful recall.
Rationale:The testing effect refers to improved long-term retention from retrieving
information. Effortful recall during self-quizzing strengthens memory traces, whereas
rereading, concept mapping, and discussion are encoding strategies that do not directly
leverage the retrieval practice advantage.
Q3.
An online course designer wants to apply cognitive load theory to a complex simulation.
Which design feature is most effective in managing intrinsic load?
Page 3
, Section A - Learning
A. Adding decorative graphics to make the B. Segmenting the simulation into smaller,
interface more engaging sequential steps with user control
C. Presenting all variables simultaneously to D. Providing extensive background
show the full complexity information before the simulation starts
Correct: B - Segmenting the simulation into smaller, sequential steps with user control
Rationale:Segmenting complex tasks reduces intrinsic cognitive load by allowing learners to
process smaller chunks. Decorative graphics add extraneous load, presenting all variables at
once overwhelms working memory, and extensive pre-training may increase load without
supporting integration.
Q4.
In a self-regulated learning intervention, students are taught to set specific goals, monitor
their progress, and adjust strategies. Which theoretical framework most directly
underpins this intervention?
A. Operant conditioning, which reinforces B. Social cognitive theory, which
desired study behaviors emphasizes reciprocal interactions between
person, behavior, and environment
C. Information processing theory, which D. Humanistic theory, which prioritizes
focuses on encoding and storage of learner self-actualization
knowledge
Correct: B - Social cognitive theory, which emphasizes reciprocal interactions between
person, behavior, and environment
Rationale:Self-regulated learning is central to social cognitive theory (Bandura), which
highlights self-observation, self-judgment, and self-reactions. Operant conditioning focuses on
external reinforcement, information processing on memory mechanisms, and humanistic
theory on personal growth, not the cyclical self-regulation process.
Q5.
Which instructional strategy is most aligned with the principles of Universal Design for
Learning (UDL) to support diverse learners?
A. Providing a single standard textbook to B. Offering multiple means of engagement,
ensure consistency across all students representation, and action/expression
C. Grouping students by ability to tailor D. Using a single assessment format to
instruction to each level measure learning outcomes uniformly
Correct: B - Offering multiple means of engagement, representation, and
action/expression
