What is trial and error learning

Biological evolution is also a form of trial and error. Random mutations and sexual genetic variations can be viewed as trials and poor reproductive fitness, or lack of improved fitness, as the error. Thus after a long time 'knowledge' of well-adapted genomes accumulates simply by virtue of them being able to reproduce.

Bogosort , a conceptual sorting algorithm that is extremely inefficient and impractical , can be viewed as a trial and error approach to sorting a list. However, typical simple examples of bogosort do not track which orders of the list have been tried and may try the same order any number of times, which violates one of the basic principles of trial and error. Trial and error is actually more efficient and practical than bogosort; unlike bogosort, it is guaranteed to halt in finite time on a finite list, and might even be a reasonable way to sort extremely short lists under some conditions.

Trial and error is usually a last resort for a particular problem, as there are a number of problems with it. For one, trial and error is tedious and monotonous. Also, it is very time-consuming; chemical engineers must sift through millions of various potential chemicals before they find one that works. Fortunately, computers are best suited for trial and error; they do not succumb to the boredom that humans do, and can potentially do thousands of trial-and-error segments in the blink of an eye.

For instance, higher bonus to factory workers, more praise to students may lead to a better performance, but no athlete can jump over the Chinese wall, whatever the intensity of motivation is provided.

Another significant aspect of this theory is that to master a complex situation or to elaborate task, practice is must. It is not possible to handle each difficult situation in a single trial, no matter what the degree of motivation or reward is. One cannot blame the entire constitution of India in one reading even if the reward is a crore of Rupees or the threat is to be shot dead otherwise. Each task initially seems to be difficult and fatiguing but as practice continues, it becomes smoother and requires less effort.

Finally, we say that habit or S-R is established. An expert driver, for instance, goes on driving, listening to the radio and taking to his friend sitting by. In the light of class room teaching blundering is a natural phenomenon associated with student learning. But, the teacher should not regard this as a symptom of inefficient teaching, because this is the way the pupils learn.

He should not be at all worried when blundering appears. Insights will emerge as the blundering progresses from simpler associations to higher units. There is not royal road to success. Actually, we learn by doing. The blundering must be directed and methods that are wholly futile must be eliminated. But at the same time the teacher must exercise, constant restraint in his supervision. Further, both punishment and reward may play a significant role in the process of learning.

But, experiments go to show that motivation is successfully handled when it is kept in the positive phase. Drastic forms of inhibition tend to spread their effects over the whole learning situation. Sometimes, the teachers impress upon the negative processes. The false response is effectively inhibited when the correct reaction is fixated and the emphasis should be on the latter process. The fixating rewards are most effective when they afford immediate and complete release.

A delay introduced between the successful performance and the releasing reward has a considerable effect on their rate of learning and co-ordination. In school, the satisfactions should be closely coupled with the activity itself otherwise the likelihood of permanent effects is small. Another aspect of motivating problem is simpler than the manipulations of tensions and releases and can be mastered by all. This is that the learner should be kept informed of his progress and promptly.

Finally, though the theory is not widely accepted for its educational significance, yet, there are certain subjects such as mathematics, tables of mathematics, memorising poetry, rules of grammar etc. All reasoning subjects afford the greatest opportunity for the application of the Trial and Error method. According to his theory the task can be started from the easier aspect towards its difficult side.

This approach will benefit the weaker and backward children. A small child learns some skills through trial and error method only such as sitting, standing, walking, running etc.

In teaching also the child rectifies the writing after committing mistakes. In this theory more emphasis has been laid on motivation. Thus, before starting teaching in the classroom the students should be properly motivated. Practice leads a man towards maturity.

Practice is the main feature of trial and error method. Practice helps in reducing the errors committed by the child in learning any concept. Habits are formed as a result of repetition. With the help of this theory the wrong habits of the children can be modified and the good habits strengthened.

The effects of rewards and punishment also affect the learning of the child. Thus, the theory lays emphasis on the use of reward and punishment in the class by the teacher. The theory may be found quite helpful in changing the behaviour of the delinquent children. The teacher should cure such children making use of this theory. With the help of this theory the teacher can control the negative emotions of the children such as anger, jealousy etc.

The teacher can improve his teaching methods making use of this theory. He must observe the effects of his teaching methods on the students and should not hesitate to make necessary changes in them, if required.

The theory pays more emphasis on oral drill work. Thus, a teacher should conduct oral drill of the taught contents. This helps in strengthening the learning more.

The theory has been criticised by various psychologists on the following grounds. Firstly, the theory is mechanical, for it leaves no room for an end or purpose in any sense whatsoever. On the contrary psychologist Mc Dougall maintained that even the behaviour of the amoeba or the paramecia consists in learning to face novel conditions to serve some unknown purpose Even repeated trials are of no avail if the tendency to learn is not there.

Again, if the tendency is there, even one trial may be fruitful. Mc Dougall and Woodworth insist on readiness for reaching a goal in learning and Lloyd Morgan lays stress on persistency with varied efforts till the goal of learning is achieved.

The hungry cat confined in the puzzle-box with food in front of it goes on persistently trying various means until it gets out of it and has food. In many ways, trial-and-error is the only form of learning we really have. This process repeated over time is the only real, effective way we have to learn more about our world and solve problems in our life.

As powerful as our minds can be, they are limited. No single mind completely understands how the universe works. At best, we only have pieces of the puzzle.

Because our knowledge is imperfect, we need to sometimes endure the pain of trial-and-error before we can better understand something.
