JKSET cheat sheet

Syllogism validity: a conclusion follows only if no model makes all premises true and the conclusion false; the middle term must be distributed in at least one premise.

Venn-diagram method for two-term categorical propositions: A (All S are P) excludes S outside P; E excludes overlap; I asserts overlap; O asserts S outside P.

Number series heuristics: check successive differences, then ratios, then alternating sub-series, then squares/cubes plus a constant offset.

Blood relations: draw a tree with gender labels; vertical links are parent-child, horizontal links are spouse or sibling, and never infer gender from a name.

Direction sense: net displacement uses vector addition; a right turn from North gives East, and consecutive turns sum modulo 360 degrees.

Coding-decoding: test letter-position shifts (A=1 ... Z=26), reversal (Atbash: position n maps to 27-n), and keyboard or alphabet-pair patterns before assuming arbitrary substitution.

Calendar rule: a normal year shifts the weekday of a fixed date by 1, a leap year by 2; 100 years give 5 odd days, 400 years give 0.

Clock rule: the minute hand gains 5.5 degrees per minute on the hour hand; hands coincide every 65 5/11 minutes.

Static awareness anchors: Article 356 covers President's Rule, Article 368 amendment procedure, and the Fundamental Duties were added by the 42nd Amendment (1976).

The JKSET paper structure pairs a common Paper I (general teaching and research aptitude) with a subject Paper II chosen by the candidate; confirm the current subject list from the official notification.

Subject papers are set at postgraduate level, so revision should follow the candidate's own master's syllabus rather than school-level textbooks.

Negative marking applies in JKSET objective papers; unanswered questions score zero, so guess only when options can be eliminated.

For literature subjects, keep a timeline of movements and periods and match each major author to one representative work and one signature idea.

For science subjects, prioritise derivations and unit analysis over memorised values; most numerical items test formula selection and dimensional consistency.

For social science subjects, anchor answers in constitutional provisions, dates of major legislation, and named committees or commissions.

For commerce and management, distinguish concepts by definitional boundary: for example, capital vs revenue expenditure, or fund flow vs cash flow.

For language subjects, grammar and usage items dominate; revise sandhi, samasa, or case endings depending on the language, plus standard idiom lists.

A variable is any characteristic that can take different values; an independent variable is manipulated or treated as cause, a dependent variable is measured as effect.

Validity types: internal validity concerns causal inference, external validity concerns generalisability, and construct validity concerns whether the instrument measures the intended concept.

Reliability is consistency: test-retest, split-half (adjusted by Spearman-Brown), and Cronbach's alpha for internal consistency; reliability is necessary but not sufficient for validity.

Sampling: probability methods (simple random, stratified, cluster, systematic) permit sampling-error estimation; non-probability methods (purposive, quota, snowball, convenience) do not.

Standard error of the mean equals the population standard deviation divided by the square root of n; larger samples shrink it.

Hypothesis testing: a Type I error rejects a true null hypothesis (alpha), a Type II error fails to reject a false null (beta); power equals 1 minus beta.

Parametric tests (t, ANOVA, Pearson r) assume approximate normality and interval data; non-parametric alternatives include Mann-Whitney U, Wilcoxon, Kruskal-Wallis, and chi-square for frequencies.

Research designs: pre-experimental (one-group pre-test post-test), quasi-experimental (no random assignment), true experimental (random assignment plus control), and ex post facto (retrospective, no manipulation).

Ethics essentials: informed consent, voluntary participation, confidentiality or anonymity, no fabrication or falsification, and proper citation to avoid plagiarism.

Teaching is a triadic process linking teacher, learner, and content; learning is a relatively permanent change in behaviour or capability resulting from experience.

Bloom's revised taxonomy orders objectives as Remember, Understand, Apply, Analyse, Evaluate, Create; lower three are often labelled LOTS, upper three HOTS.

Piaget's stages: sensorimotor (0-2), preoperational (2-7), concrete operational (7-11), formal operational (11+); conservation appears in the concrete operational stage.

Vygotsky's Zone of Proximal Development is the gap between independent performance and assisted performance; scaffolding is temporary support withdrawn as competence grows.

Kohlberg's moral development: preconventional (punishment, self-interest), conventional (approval, law and order), postconventional (social contract, universal principles).

Learner-centred approaches include inquiry-based, problem-based, and cooperative learning; teacher-centred approaches include lecture and demonstration.

Formative assessment is ongoing and diagnostic; summative assessment certifies achievement; norm-referenced compares to a group while criterion-referenced compares to a standard.

Higher-education bodies in India: UGC regulates standards, NAAC accredits institutions, NIRF ranks them, and the UGC NET or SET determines eligibility for assistant professor and JRF.

ICT in teaching: LMS hosts content and assessment, MOOCs such as SWAYAM offer open courses, and blended learning combines face-to-face with online delivery.
