New math: Fail + try again = real learning

Teachers increasingly urge students to risk failing as a route to ultimate

success

By Susan Moran

2015

PART A: Which statement identifies the central idea of the text?

A. Math is best taught using discovery-based learning as people are more likely to  fail in math.

B. Allowing and encouraging people to fail helps them to make sense of what they  are learning.

C. Although people can learn even when they fail at least once, they are still  negatively affected by their failure.

D. Younger people learn better through hands-on activities that can result in  failure, while adults learn better through risk-free lectures.

2. PART B: Which detail from the text best supports the answer to Part A?

A. “A century ago, after five months and more than 9,000 experiments, famed  inventor Thomas Edison still wasn’t able to make a new type of storage battery  work, according to a 1910 authorized biography.” (Paragraph 5)

B. “‘If you’re engaged in a hard problem, you’re developing an attitude that failure  is okay,’ says Walker. ‘Accepting failure helps you learn’” (Paragraph 9)

C. “As Walker suggests, the technique often goes hand-in-hand with inquiry-based  learning. Students often teach and mentor one another.” (Paragraph 14)

D. “A related approach is also seeping into K-12 math education. Common Core is a  set of educational standards that 43 states and the District of Columbia have  adopted.” (Paragraph 20)

B. “‘If you’re engaged in a hard problem, you’re developing an attitude that failure  is okay,’ says Walker. ‘Accepting failure helps you learn’” (Paragraph 9)

Explanation:

The article´s main idea is that failing can benefit education because mistakes help us learn and develop creative ideas.

Teachers who have applied the “guide on the side” teaching style found that their students learned that failure could lead to new ideas and discoveries. Furthermore, scientific research claims that those students learn more with this approach.

not sure how to answer your question sorry

in my opinion, ap calculus was the most difficult. i often struggled with it a lot. however, i have gotten a lot better.
