** What’s Inside**

Lecture (30 slides) — 4 sections with a distinctive purple/violet palette:

S01 Imperative: procedural (Python subroutine code), OOP (four principles, class diagrams), procedural vs OOP side-by-side code
S02 Declarative: core concept, imperative vs declarative comparison table, functional (Haskell + Python code), pure functions feature table, recursion worked example, Prolog facts/rules/queries code slide
S03 SQL as declarative: Python loop vs SQL SELECT side-by-side code, paradigm selection worked example
S04 Paradigm comparison table (all 5 paradigms: procedural, OOP, functional, logic, SQL), summary, exam techniques mapped to Cambridge/AQA/OCR/GCSE

Worksheet — Sections A–D: definitions, code analysis (annotating Python procedural code), OOP term table, Haskell recursion trace (factorial 4), Prolog query evaluation, SQL writing task, and 6- and 9-mark extended response questions including a hospital system paradigm evaluation.

Activity — Spot the paradigm (4 code snippets), rewrite a procedural program in functional style and SQL, paradigm debate (3 teams), and a manual Prolog family tree query exercise with backtracking explanation.

MCQ Quiz — 20 questions across Q1–5 (imperative/OOP), Q6–11 (functional), Q12–15 (Prolog/SQL), Q16–20 (applied paradigm selection).

Marking Scheme — Point-marked model answers for all 15 worksheet questions, MCQ key with 6 misconception notes, and detailed activity facilitation guidance including correct Prolog query traces.
