Harvard physicist Eric Mazur explains how he realized his students were memorizing rather than understanding, and how he changed his teaching. He presents peer instruction and data showing improved student performance.

Patrick Winston's long-running MIT lecture on public speaking teaches heuristic rules for talks. It covers how to start, use time and place, boards, props and slides, and how to inform, persuade and finish.

First lecture of Stanford's CS106A Programming Methodology by Mehran Sahami, giving a course overview and starting on programming. The course teaches software engineering principles using Java.

Thomas Garrity discusses mathematical maturity, a concept mathematicians use for professional development, and how it can inform teaching, mentoring and careers. It was given at the IAS/PCMI Park City Mathematics Institute.

Psychology professor Marty Lobdell gives a one-hour lecture on how to study effectively, covering short focused sessions with breaks, study environment, note-taking and memory techniques. It was aimed at students who cram without improving.

Casey Muratori's lecture, originally given at the Technical University of Madrid, arguing that Conway's Law is the only viable candidate for a true law of software architecture. He explains how software mimics the organization over time, using examples like Windows' multiple volume controls.

An RSA Animate drawn from a Sir Ken Robinson talk arguing that current education systems are modeled on the industrial age. It discusses divergent thinking, standardization, and how schools disengage kids.

Larry McEnerney of the University of Chicago Writing Program argues that good writing is defined by what readers value, not by rules or the writer's own ideas. He explains why academic habits fail outside academia and how to write so readers find the work valuable.

Thomas Ricks's Nimitz Memorial Lecture at UC Berkeley asks why US generals did better in World War II than in Korea, Vietnam or Iraq and Afghanistan. A central point is the WWII practice of quickly reassigning or relieving underperforming generals.

Weber State's Professor Kelly explains the Toyota RAV4 Hybrid transaxle, including its planetary gearset eCVT and all nine operating modes. It also covers how the engine reaches nearly 40 percent thermal efficiency.

An eight-minute excerpt of a 1983 video featuring Seymour Papert, creator of Logo, on children learning programming and abstract ideas through embodied play. It shows kids acting out the Logo turtle.

Chuck Spinney, a long-time associate of John Boyd, presents Boyd's thinking on the OODA loop and evolutionary epistemology. The talk runs about two and a half hours and includes Q&A.

Clayton Christensen explains disruptive innovation using the steel industry, showing how mini-mills beat incumbents from the low end. He argues disruption is not about stupid or bad management.

Professor Jeff Dahn lectures on why lithium-ion batteries die and how chemistry changes could make them last decades.

A 15-minute clip of linguist Stephen Krashen discussing language acquisition, drawn from the 1980s. It presents his input hypothesis and the distinction between acquisition and learning.

A lecture from the 1980s by linguist Stephen Krashen on how people acquire language. He explains his comprehensible input hypothesis for second-language acquisition.

Clayton Christensen explains his theory of disruptive innovation at Oxford's Said Business School, using examples from steel, Toyota, Sony, Walmart and Godrej. He applies the theory to why some economies stagnate and others grow.

The preface to Herb Gross's MIT OpenCourseWare 'Calculus Revisited: Single Variable Calculus', an older black-and-white lecture series. It introduces his approach to teaching calculus from the basics.

The first episode of Michael Sandel's Harvard course on moral reasoning, opening with the trolley problem and the choice between killing one to save five. Sandel draws out student arguments and introduces utilitarian and other approaches to justice.

The first lecture of Gilbert Strang's MIT 18.06 Linear Algebra course, covering the geometry of linear equations. It opens a full 35-lecture university course.

Part 1 of a lecture by physicist Albert Bartlett on the exponential function and its consequences for population growth, resource use and energy. It argues that steady growth rates quickly lead to enormous quantities.

A lecture from MIT's Missing Semester course covering version control with git. It builds up git from its data model rather than from commands.

A roughly three-hour San Francisco workshop by Marshall Rosenberg on Nonviolent Communication, with full English subtitles added by a fan. He teaches the model with his jackal and giraffe language examples.

Physicist Al Bartlett's well-known lecture on the arithmetic of exponential growth, applied to population, energy consumption and resource depletion. He argues that steady percentage growth cannot be sustained on a finite planet and that most public discussion ignores this.

A recording of physicist Albert Bartlett's well-known lecture on the arithmetic of exponential growth, applied to population and energy use. He argues that steady percentage growth in a finite world cannot continue and sneaks up suddenly.

The first lecture of Francis Su's Harvey Mudd real analysis course, covering the construction of the rational numbers. It begins a full lecture series that follows a standard analysis text.

The first lecture of Stanford's CS107 Programming Paradigms, taught by Jerry Cain, giving an overview of the course. The course goes from C and assembly through C++, concurrency, Scheme and Python.

First video in John Bartholomew's Chess Fundamentals series, focused on spotting undefended pieces. He teaches habits for scanning your own and your opponent's position to avoid hanging pieces.

Physicist Albert Bartlett's full-length lecture on how steady exponential growth in population and energy use collides with finite resources. It uses examples like bacteria in a bottle and covers peak oil.

Tyler Bosmeny, CEO of Clever, gives a Y Combinator Startup School talk on how early-stage companies should approach sales and build an enterprise sales team.

A lecture by Commodore Grace Hopper on the future of computing, posted by MIT Lincoln Laboratory. It includes her well-known nanosecond wire demonstration and humorous comparisons of device latencies.
