Prime numbers are numbers that are only divisible by 1 and themselves. So, to tell if a number is prime, look at its factors.
19:
1 x 19
29:
1 x 29
39:
1 x 39
3 x 13
So, because 39 has more than one set of factors, it's NOT a prime number.
Answer: Anonymity allows students to freely express their concepts and criticisms without feeling that they are judged by others.
Explanation:
In the educational field, students are not only focused on learning the curricular contents taught by teachers, but the social part where they create friendships with each other is also involved. When a student has to make constructive criticism of another classmate, it often does not think about whether the work it did but how its criticism can affect the friendship it has with the person, which interferes to express an objective opinion.
Anonymity would be very useful in this class because it allows students to express their point of view without feeling that they will be judged by their classmates. When a student feels that it can give its opinion, knowing that it will not interfere with their friendship, it feels freer and speaks more clearly.
It is normal to see how sometimes a student can change his behavior towards another if he feels that it expressed itself in a way he did not like about the work done. This gets to interfere with their social dynamics, leading them to the point of losing a friendship. A student does not want to be in a classroom where it knows that his classmate does not want to see him.
If teachers implement anonymity in the feedback process, they will find more extensive opinions and criticisms in the learning process. They will see that students are going to talk more objectively since they will not feel the pressure that they will be signaled by their opinions.
