How does Khan's comparison of learning to building a house contribute to the meaning of the text? (From CommonLit "Let's Teach for Mastery- Not Test Scores")

It is critical that pupils understand and master topics/texts. What is fixed is that they have a through understanding of the subject/topic.

Sal Khan is concerned with a student's mastery of a subject or topic.

He compares learning to the process of constructing a home, which begins with the hiring of a contractor. He starts laying the floors after laying the foundation and making around 75% work on the foundation.

He builds the first and second story on a damp foundation and then starts on building the third, but everything falls at this point. If a student receives an 80 percent in a class, this indicates that he still needs to grasp and master the remaining 20%.

Sal Khan focuses on student's mastery on subject/topic.

He compares learning to the building of a house which a building contractor commences. Having laid the foundation and made about 75% progress on the foundation laying, he proceeds to laying the floors. He lays the 1st, 2nd floors on a wet foundation and moves to lay the 3rd floor but at this time everything collapses.

The process truly matters.

A student who haven't mastered a text/topic and goes ahead to another class or topic may encounter a problem in the upper level. If a student scores 80% in a class, it shows that there is a 20% which he is yet to grasp and master.

It's very important students comprehend and master topics/texts before heading to the next stage. What is fixed is that they actually master the subject/topic/text.
