Examine above two statements carefully and select the correct answer from the option given below:

A

Both (A) and (R) are true and (R) is the correct explanation of (A)

B

Both (A) and (R) are true and (R) is the not correct explanation of (A)

Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions. Which kind of assessment is depicted by this situation?

A

Assessment OF Learning

B

Assessment for Learning

C

Assessment AS Learning

D

Assessment by learning

Teenagers' brains really are different from those of their parents and a fully adult brain may not develop until well after the teenage years. R. For their parts, adolescents can't understand what their parents are worried about; they find their tastes and responsible concerns boring and outdated S. From an adult point of view, adolescents are difficult, rebellious, irresponsible, often selfish, and self-absorbed, prone to dangerous behaviour that risks their health, their life, and their possibility of future happiness. S6: This new knowledge, it is hoped, will help all of us deal better with the difficult and often painful years of transition from childhood to adulthood.
