"From the Ted Talk by Sal Khan: Let's teach for mastery -- not test scores"

#### Unscramble the Blue Letters

Even though we've identified the gaps, the whole calss will then move on to the next subject, probably a more aecdvand subject that's going to build on those gaps. It might be logarithms or neigvate eponntexs. And that process continues, and you ildetmmeiay start to realize how strange this is. I didn't know 25 percent of the more foundational thing, and now I'm being phsued to the more advanced thing. And this will continue for months, years, all the way until at some point, I might be in an algebra class or trigonometry class and I hit a wall. And it's not because algebra is fundamentally dfclifiut or because the student isn't bright. It's because I'm seeing an equation and they're dealing with exponents and that 30 percent that I didn't know is showing up. And then I start to disengage.

#### Open Cloze

Even though we've identified the gaps, the whole **_____** will then move on to the next subject, probably a more **________** subject that's going to build on those gaps. It might be logarithms or **________** **_________**. And that process continues, and you **___________** start to realize how strange this is. I didn't know 25 percent of the more foundational thing, and now I'm being **______** to the more advanced thing. And this will continue for months, years, all the way until at some point, I might be in an algebra class or trigonometry class and I hit a wall. And it's not because algebra is fundamentally **_________** or because the student isn't bright. It's because I'm seeing an equation and they're dealing with exponents and that 30 percent that I didn't know is showing up. And then I start to disengage.

#### Solution

- negative
- exponents
- pushed

#### Original Text

Even though we've identified the gaps, the whole class will then move on to the next subject, probably a more advanced subject that's going to build on those gaps. It might be logarithms or negative exponents. And that process continues, and you immediately start to realize how strange this is. I didn't know 25 percent of the more foundational thing, and now I'm being pushed to the more advanced thing. And this will continue for months, years, all the way until at some point, I might be in an algebra class or trigonometry class and I hit a wall. And it's not because algebra is fundamentally difficult or because the student isn't bright. It's because I'm seeing an equation and they're dealing with exponents and that 30 percent that I didn't know is showing up. And then I start to disengage.
