why learning occurs but there is no change in behavior?

Bandura mentions four conditions that are necessary before an individual can successfully model the behavior of someone else:

1.  Attention: the person must first pay attention to the model. 
2. Retention: the observer must be able to remember the behavior that has been observed. One way of increasing this is using the technique of rehearsal.
3. Motor reproduction: the third condition is the ability to replicate the behavior that the model has just demonstrated. This means that the observer has to be able to replicate the action, which could be a problem with a learner who is not ready developmentally to replicate the action. For example, little children have difficulty doing complex physical motion.
4. Motivation: the final necessary ingredient for modeling to occur is motivation, learners must want to demonstrate what they have learned. Remember that since these four conditions vary among individuals, different people will reproduce the same behavior differently.

above is some scripts i detrieved from http://teachnet.edb.utexas.edu/~Lynda_abbot/Social.html


i would give some new examples for each of the 4 conditions above:

1. Attention--this condtions result in no behavioral changes most of the time, for example, when a teacher is showing steps to solve an algebraic problem, but the students do not pay attention to the details, then the students most probably will not be able to solve other algebraic problem.
2. Retention--we learn lotz of things everyday, sometimes we might forget it easily. For example, students may had learn the formula for finding roots of quadratic equatic, however, after sometime he forget about the formula & can not perform the operation.
3. Motor reproduction--example, a student may had learn that when people get drown, we need to save the person and maybe need to perform CPR, however, cannot perform CPR as he do not know how to swim or do not know the correct steps to perform CPR. Similarly, some students cannot find the area under the curve because they do not master the technique of integration.
4. Motivation--through our education, and mass media, we all learn that we must keep our environment clean. But, some people, however, reluctant to do it, they will throw rubbish anywhere and refuse to pick up the trash on the floor. Similarly, some students have learn how to solve certain problem, but they refuse to do it as it do not bring much satisfaction to them.

Difference between Classical and Operant Conditioning



source: http://faculty.mdc.edu/jmcnair/Joe14pages/basics_of_behaviorism.htm

in my own example, it would be like this

classical conditioning: whenever a teacher want to ask (uncondtitioned stimulus) students do exercise, she would take out the workbook (conditioned or neutral stimulus), the students will do the exercise (unconditioned respon); after some repetition, once the student see the workbook (conditioned stimulus), they will start doing exercise (conditioned respons).

operant conditioning: students do the exercise given (respons), teacher give a compliment (stimulus, reward); after some time, students understand that if he want to get compliment (conditioned stimulus, reward), he must do the homework (conditioned respons) .

hope my thought is correct....
if u think the other way other, pls don't shy to tell me : )
