1. In a paragraph each, describe the following theories: Ivan Pavlov and classical conditioning, B. F. Skinner and operant condi
Andreyy89

Learning theories explain how information is received, processed, and retained by students while they are learning.

Russian physiologist Pavlov first identified classical conditioning, which involves learning through association. Simply said, two stimuli are combined to cause a person or animal to learn a new learned response.

Operant conditioning is a form of associative learning in which the strength of a behavior is altered by reward or punishment.

Albert Bandura's social learning theory places a strong emphasis on the value of seeing, modeling, and copying other people's behaviors, attitudes, and emotional responses.

Heat up the stove, let it cool to a point where it would still sting a child's tender fingertips but not burn them, and then allow the child to touch it to teach them to avoid touching hot surfaces.

Place the youngster on the toilet and reward them if they excrete.

Encourage the kid to pay attention to how you behave at the table. Make them aware of your good manners, and they'll start to imitate you.
