Further Reading — Chapter 30: Slide Design

Annotated, Tier 1 and Tier 2 sources only. Start with Alley if you read just one — it is the source of the assertion–evidence approach this chapter is built on.

Tier 1 — Verified landmark works

Michael Alley, The Craft of Scientific Presentations (Springer). The book behind this chapter's central technique. Alley and colleagues developed and tested the assertion–evidence slide — a full-sentence claim as the headline, a single visual as the body — and showed it improves audience comprehension and retention over the standard topic-and-bullets format. Read it for the evidence base, the many before/after slide examples, and the chapters on talk structure and handling questions. The single most useful book on this topic for technical presenters. (See also the assertion-evidence.com teaching materials associated with this work.)

Garr Reynolds, Presentation Zen: Simple Ideas on Presentation Design and Delivery (New Riders). The most influential popular argument for restraint in slide design. Reynolds makes the case — with an aesthetic eye and many examples — for simplicity, one idea per slide, big visuals, and lots of empty space, against the bullet-point deck. Where Alley is the rigorous research source, Reynolds is the persuasive, design-minded companion that will change how you look at slides. Pair the two.

Nancy Duarte, slide:ology: The Art and Science of Creating Great Presentations (O'Reilly). A deep, practical treatment of slide craft from a designer who has built decks for major talks. Strong on visual hierarchy, turning data into clear slide graphics, using color and type with intent, and the discipline of designing each slide around a single idea. Excellent complement to this chapter's back-row test and data-ink sections; consult it when you want to go beyond the defaults into genuinely well-designed visuals.

Edward R. Tufte, The Visual Display of Quantitative Information (Graphics Press). The source of the data-ink principle this chapter applies to slide charts: maximize the ink that represents data, delete chartjunk (3-D, heavy gridlines, gradients, redundant legends, rainbow color). Tufte also wrote a pointed essay, The Cognitive Style of PowerPoint, arguing that the bullet-driven slide format degrades reasoning — provocative and worth reading as the strongest case against slides as usually built. (Returns from Chapter 9.)

Tier 2 — Attributed ideas and widely-cited frameworks

Guy Kawasaki — the 10/20/30 rule. Kawasaki, a venture capitalist who has endured thousands of startup pitches, proposed the rule of thumb that a presentation use about 10 slides, last no more than 20 minutes, and use no font smaller than 30 point. He has written about it in his books and widely-read posts; it's a blunt, memorable heuristic aimed at pitches but useful as a general audit. Treat the exact numbers as a rule of thumb, not a law (the chapter explains why the spirit — few points, tight time, big type — matters more than the precise count).

Research on cognitive load and the "redundancy effect" (Sweller, Mayer, and colleagues; Tier 2). The reason a text-dense slide narrated aloud fails has a name in the learning-sciences literature: presenting the same verbal information in both on-screen text and spoken narration creates a redundancy effect that hurts comprehension, because the two compete for the same channel. The broader work on cognitive load theory (Sweller) and multimedia learning (Mayer) is the empirical backbone for "the audience reads OR listens, never both." Read it if you want the science under the threshold concept; cite the ideas, which are well established, rather than inventing specific figures.

A note on honesty: the epigraph in this chapter's index.md ("Tell me the facts and I'll learn…") is widely quoted in presentation training but has no reliable attribution; it is labeled as folklore there, not credited to a source. Where this chapter states ideas it can't pin to an exact page or study (the redundancy effect, the 10/20/30 rule's reasoning), it attributes them to the people and bodies of work above without fabricating DOIs, years, or quotations.
