Part 1: Selecting & Creating Media to Support Instruction
A 4-minute lesson built for LT 7100, Instructional Design, in the Georgia State University M.S. Instructional Design & Technology program. Media is easier to make than ever, but not any easier to learn from. This video gives designers one question to decide what earns a place on screen.

What it covers
1 · Two limited pipes
Mayer's Cognitive Theory of Multimedia Learning: separate visual and auditory channels, each with limited capacity, and the three kinds of processing a design can reduce, manage, or foster.
2 · Select before you create
Start from what the learner actually has to do: compare, follow a process, recognize a sound, or practice a decision, and match the medium to that task.
3 · Creating, with AI in the room
AI speeds up production but lacks pedagogical intuition. Treat outputs as drafts and check them for accuracy, accessibility, and the right to use them.
How it was made
Design
Script written and locked by the instructor, grounded in Mayer's multimedia learning research
A deliberately calm, Vox-style paper-collage look: no fly-ins, elements fade up in place, motion only where motion is the content
Media
Still images from GPT Image 2.5 against a single style frame; two short B-roll clips from Grok Video 1.5
Narration in a Higgsfield preset voice, with pauses tightened and loudness set to −16 LUFS
Build
A GSAP scene engine in HTML, with every label timed to the spoken word by audio alignment
Rendered frame by frame in headless Chromium and assembled with FFmpeg behind the branded LT 7100 splash
