Question 1
What is neuroplasticity?
A) The brain's fixed structure determined at birth
B) The brain's ability to reorganize and form new neural connections in response to learning
and experience
C) A measure of intelligence quotient
D) The process of brain cell death
Answer: B) The brain's ability to reorganize and form new neural connections in response to
learning and experience
rationaLe: Neuroplasticity is the biological foundation of learning. Every time we learn
something new, the brain physically changes by strengthening or creating new pathways
between neurons (synapses). This ability continues throughout life .
Question 2
Which brain structure is primarily responsible for consolidating short-term memories into long-
term memories?
A) Cerebellum
B) Amygdala
C) Hippocampus
D) Brain stem
Answer: C) Hippocampus
rationaLe: Located in the limbic system, the hippocampus plays a crucial role in forming
new explicit memories and consolidating them for long-term storage. Damage to the
, hippocampus impairs the ability to form new explicit memories, though older memories may
remain intact .
Question 3
What is the primary role of the prefrontal cortex in learning?
A) Coordinating motor movements
B) Regulating emotions and motivation
C) Managing executive functions such as planning, attention, impulse control, and decision-
making
D) Processing sensory information
Answer: C) Managing executive functions such as planning, attention, impulse control, and
decision-making
rationaLe: The prefrontal cortex acts as the CEO of the brain. It allows students to set
goals, focus attention, organize tasks, and ignore distractions. Executive function includes the
cognitive ability to organize, strategize, and plan behavior .
Question 4
According to Vygotsky, the guidance provided by a teacher or peer to help a learner
accomplish a task within their Zone of Proximal Development (ZPD) is called:
A) Direct instruction
B) Scaffolding
C) Operant conditioning
D) Discovery learning
Answer: B) Scaffolding
rationaLe: Scaffolding provides structured, temporary support that is gradually removed
(faded) as the learner becomes more competent. This allows them to move through the ZPD
toward independence. The ZPD is the gap between what a learner can do independently and
what they can achieve with guidance .
