CONTENT STUDIO PREVIEW

1. Official curriculum anchor

S2-ALG.4 · Strand 2: Core concepts · Sorting and search

apply basic search and sorting algorithms and describe the limitations and advantages of each algorithm

Higher|Ordinary · Leaving Certificate Computer Science updated specification — examinations 2025 onward

2. Original iLEARN experience

  1. Learning intention: work directly toward S2-ALG.4.
  2. Entry: short original explanation plus key vocabulary.
  3. Active task: use one of the recommended formats below.
  4. Check: learner explains, applies or demonstrates the outcome.
  5. Improve: feedback then retry/redraft.
  6. Evidence: save the improved response against CS-SC-CURRENT-S2-ALG-4.

3. Recommended content formats

  • Worked example — model problem · visible steps · faded second example · independent try
  • Original practice sheet — scaffolded items · mixed practice · self-check · extension
  • Micro explainer — short explanation · key vocabulary · one worked example · one misconception check
  • Visual summary / poster — original diagram plan · labels · short captions · text equivalent

Originality rule: new wording, examples, questions, datasets, diagrams and sequences. Publisher material is not copied or stored.

4. Required learner variants

Easy English · Standard English · Exam/subject language

Easy / Standard / Exam English · Read aloud · Reduced motion · Chunked instructions · Voice or typed response · Vocabulary support · Non-visual / non-drag alternative when needed

5. Teacher control

The authenticated Content Studio backend now supports preview → save draft → teacher edit → approve. Nothing becomes learner-visible by default.
