Shadowing Bill Gates

Teachers Need Real Feedback — Gates discusses coaching and feedback for teachers, including an example of recording lessons for review. School vocabulary and explanations of improvement are central to the captions. Original video on YouTube: Bill Gates — Teachers Need Real Feedback.

Summary

Bill Gates argues that teachers need the kind of specific feedback and coaching that athletes and other professionals routinely receive. A generic satisfactory rating gives little guidance about improving classroom practice. He describes international examples of teachers observing colleagues and discusses the Measures of Effective Teaching project, which combined classroom videos with student surveys. A teacher's demonstration shows how recording a lesson can turn a vague impression of teaching into concrete material for reflection and professional learning.

Key points, in order

Gates points to Shanghai's mentoring, study groups, and peer observation as examples of organized support for teachers. His concern is how to spread effective practice across an education system.
The project he describes involved 3,000 teachers. Observers assessed practices such as asking challenging questions and explaining ideas in different ways, while students contributed their experience through surveys.
English teacher Sarah Brown Wessling demonstrates a simple camera setup and explains how watching footage and taking notes help her reconsider instruction and classroom management.
Diagnosis must lead to useful resources, such as examples of excellent teaching. Gates also emphasizes teachers' control over recordings and lesson selection, and acknowledges that a complete improvement system requires significant investment.

What this talk trains

Bill Gates speaks for about 10 minutes: roughly 1,510 words in 125 caption lines. The pace stays fairly even, about 133 words a minute in the first quarter and 137 in the last. Overall it is faster than 27 of the other 66 talks on Sada. Its sentences average 14.2 words, no longer than the middle of the library (14.3), and 10.3% of its words fall outside the 3,000 most common English words (library middle: 12.9%). It asks 11 questions, so there is plenty of question intonation to copy. Phrases that fast speech often shortens come up again and again: “want to” (3 times) and “a lot of” (2 times).

Lines from across the talk, and what each one trains

One line from each quarter of the talk. Press a line to open it in Sada, ready to record. “Linking” marks words that run together: a word ending in a consonant sound joins the vowel that starts the next one.

2:34 Now, out of all the places that do better than the U.S. in reading,
“out of”: fast speech often shortens it to “outta”. Listen for whether the speaker does here. Linking: say “out of”, “of all” without a break between the words.
3:41 You might ask, why is a system like this so important?
A question: listen to where the voice rises or falls at the end, and copy it. Linking: say “might ask”, “is a” without a break between the words.
5:35 To get started, we're doing a peer review day, okay?
A question: listen to where the voice rises or falls at the end, and copy it. Several commas: say it in short chunks first, then as one line.
8:18 We also have to give them the tools they need to act on the diagnosis.
“have to”: fast speech often shortens it to “hafta” when a verb follows. Listen for whether the speaker does here. One of the quicker lines: about 184 words a minute by the caption timing, against 151 for the whole talk.

Words that keep coming up

Words outside the 3,000 most common English words that Bill Gates uses more than once. The number is how often each is said. Look up any you don’t know, then press it to practise the line where it first comes up.

How to practise this talk

Warm up on the slowest minute (from 0:18) or on the opening lines above.
Then take the chosen lines above one at a time: a shortened phrase, linked words, a question, a line said in chunks, a quick line.
On each line, press Record and say it after Bill Gates (Repeat) or along with them (Shadow), then open Compare and go again until every word is green.
Save the fastest minute (from 5:39, about 221 words a minute) for last.
At one minute a day you finish the whole talk in about 10 days, and Sada shows your first try against your latest.
