Causes of Errors

c. Incomplete Application of Rules

It happens due to life deviation of structure that neglects the development of rules to produce the acceptable sentence. For example: in teaching foreign language, teacher often uses question as a teaching device to get the learner's responses. The learners' incomplete knowledge of the target.

Language makes them neglect the rules of the target language in answering or giving responses to the teacher's questions. Some examples are as follows: Teacher's questions Student's response

Do you know her name?

Yes, l know

Ask him how much it costs How much it cost?

d. False Concepts Hypothesized

It happens due to misconception of the difference in the target language. The low teaching techniques sometimes create this error comprehension. For instance, in the teaching of present tense the teacher usually starts with the teaching of to be am, is, are, then teaching the verbs. It is also often found in the teaching of past tense. When the teacher presents the items poorly, the learner may have a false assumption. Such as am, is are the sign of present activities and was, were, are the sign of past activities. As the result the learner may produce sentences as like,

 He is comes here,

I am study English every day, 

They were played football yesterday.
