Teaching and Research Aptitude
This domain tests two linked competencies: how teaching is planned and assessed, and how research is designed and reported. Items range from conceptual MCQs on Bloom's taxonomy, teaching methods and sampling to short application questions that ask you to identify a variable, a design flaw or an assessment type.
Teaching concepts that recur
- Learner-centred teaching shifts decisions about pace and method to the learner; andragogy (Knowles) assumes adults are self-directed and problem-centred, unlike pedagogy.
- Bloom's revised taxonomy runs Remember → Understand → Apply → Analyse → Evaluate → Create; the verb in the question signals the level.
- Formative assessment gives feedback during learning; summative assessment judges at the end; diagnostic assessment precedes instruction.
- Methods differ in purpose: lecture (efficient transmission), discussion (higher-order processing), demonstration, project and problem-based learning, team teaching.
Research concepts that recur
- Variables: independent (manipulated), dependent (measured), extraneous (controlled), confounding (uncontrolled and linked to both).
- A hypothesis must be testable and falsifiable; the null hypothesis states no difference or relationship and is what statistical tests actually evaluate.
- Probability sampling (simple random, stratified, cluster, systematic) supports generalisation; non-probability sampling (purposive, convenience, snowball) does not.
- Validity means measuring what you claim; reliability means consistency. A test can be reliable yet invalid, but cannot be valid without being reliable.
- Ethics: informed consent, voluntary participation, confidentiality versus anonymity, no fabrication or plagiarism.
Worked example
A teacher wants to test whether weekly quizzes raise achievement in a 60-student class, but cannot reassign students to sections. Identify the design and variables. Reasoning: the independent variable is the weekly quiz schedule, the dependent variable is achievement; because intact sections are used, random assignment is absent, so the design is quasi-experimental (pre-test/post-test, non-equivalent groups). The conclusion must be phrased as association, not proof of causation.
Traps that cost marks
Calling an "Apply" item "Understand" because the wording sounds descriptive; treating a null hypothesis as the researcher's prediction; thinking a reliable test is automatically valid; and confusing anonymity (identity unknown) with confidentiality (identity known but protected).
