Training Development and Materials
Build to the blueprint
Development turns objectives into materials: slides, participant guides, instructor guides, job aids, activities, and assessments. The governing rule is alignment - every element traces to an objective, and every objective has a practice opportunity and an assessment.
Manage cognitive load. Working memory is small; extraneous load is anything the learner processes that does not serve the objective. Split attention (diagram on one page, labels on another), redundancy (bullet text read aloud word-for-word), and decorative graphics all add load without adding learning. Mayer's multimedia principles - coherence, signaling, contiguity, segmenting - are practical checks.
Write for the audience. Plain language and a defensible readability level matter more in safety training, where comprehension is a legal expectation. Use concrete examples from the learners' own equipment and tasks.
Distinguish training from support. A well-built job aid (checklist, placard, quick reference) often beats memory-based training for infrequent, high-consequence tasks. Do not build a course where a checklist solves the problem.
Pilot and revise. Run a dry run with a representative learner group, time the activities (developers almost always underestimate practice time), and revise. Control versions so the instructor guide, participant guide, and slides never drift apart.
Trap: the question offers "add more content" or "add graphics for visual interest" as a fix for poor comprehension - the correct answer is usually to reduce load, chunk content, or simplify language.
Rule of thumb: if an element cannot be traced to an objective, cut it or move it to a reference document.
Worked example: A confined-entry course carries 60 slides for a 45-minute block. The fix is not better slides; it is cutting content that supports no objective and converting the permit checklist into a hands-on job aid.
