Research & Methods
Defining "classroom engagement" as the specific number of times a student attends to an assigned task during a 20-minute window is an example of this scientific process.
What is operationalization?
This theorist is most closely associated with identifying psychosocial developmental crises across the entire human lifespan.
Who is Erik Erikson?
Modern developmental science views nature and nurture not as opposing forces, but in this continuous manner.
What is an ongoing interaction (bi-directional interaction)?
Myelination enhances neural functioning primarily by performing this function in the nervous system.
What is increasing the speed and efficiency of neural signal transmission?
Daily Double: Nature & Nurture
Explain why "nature vs. nurture" is an oversimplification and provide one concrete example showing how biological and environmental factors interact.
If a measure yields virtually the same score every time it is given, but does not actually measure what it claims to measure, it possesses this property combination.
What is reliable, but not valid?
A teacher praising hand-raising to increase its frequency demonstrates this learning theory mechanism.
What is operant conditioning (or B.F. Skinner's theory)?
This term refers to modifications in gene expression or activity that occur without altering the underlying DNA sequence.
What is epigenetics?
The brain process involving the selective elimination of underused neural connections to streamline processing is called this.
What is synaptic pruning?
Daily Double: Correlation vs. Causation
Explain why a correlation between social media use and sleep problems in teens does not prove causation, and name one potential confounding third variable.
In a study examining background music and reading comprehension where the researcher alters the music exposure, reading comprehension serves as this type of variable.
What is the dependent variable?
A child observing a peer ask for help and subsequently imitating that exact behavior illustrates this perspective.
What is Social Learning Theory / Social Cognitive Theory (or Albert Bandura)?
This is the correct chronological sequence of the three major prenatal developmental periods.
What are germinal -> embryonic -> fetal?
This concept describes the brain's capacity to reorganize its structure and neural networks in response to experience.
What is neuroplasticity?
Daily Double: Theoretical Contrast
Compare how TWO different developmental theories explain a student avoiding difficult work, and give one instructional response for each.
This specific research methodology provides the strongest empirical evidence that one variable directly causes a change in another.
What is an experiment?
This ecological framework posits that development is shaped through interacting environmental systems ranging from family and school to broader culture.
What is Ecological Systems Theory (or Urie Bronfenbrenner)?
Any environmental agent, drug, or exposure that can cause damage or interfere with prenatal development is known as this.
What is a teratogen?
A teacher incorporating movement breaks based on how attention, physical state, and learning impact one another relies on this perspective.
What is brain-body integration?
Daily Double: Educational Neuroscience
Pick ONE concept (myelination, synaptic pruning, neuroplasticity, or brain-body integration), explain it, and describe one practical teaching or caregiving application.
This research design tests multiple age groups simultaneously at one point in time to uncover developmental differences, but is vulnerable to cohort effects.
What is a cross-sectional design?
This Vygotskian concept refers to the distance between what a learner can accomplish independently and what they can achieve with guidance or collaboration.
What is the Zone of Proximal Development (ZPD)?
Name 3 possible teratogens.
What are: Drugs, Alcohol, Infections, Environmental Toxins, Maternal Health Conditions, etc.?
Located in the frontal lobe, this brain region matures late in adolescence and is responsible for executive functions such as planning, impulse control, and decision-making.
What is the prefrontal cortex?
Daily Double: Research Design Application
Design a brief hypothetical study examining how sleep duration impacts memory retention in middle childhood. Identify the independent variable, dependent variable, control measures, and one ethical consideration.
