Then, there were several reasons why the students had difficulties in determining case. They were: 1) Many types of case given by a lecturer made the students difficult to remember them. 2) The students were confused with the types of case because a noun phrase can have more than one type. 3) The students felt difficult to distinguish between accusative and dative case. 4) The students did not master English grammar well
