Improving elementary school student oral proficiency in Indonesian especially among the upper graders (i.e. the 3rd through sixth graders) can be done by means of conversation and information-sharing. In the conversation activity the class is divided into small groups each group is assigned to respond to a story or a reading passage. Through this activity the students have the opportunity to initiate a conversation to do turn taking to continue an on-going conversation to tolerate different opinions to express their thoughts and feelings to refer to their friends opinions and to end a conversation. Besides conversation information-sharing is also useful for developing students oral proficiency in Indonesian. The information-sharing activity helps students to develop their skills in presenting information putting forward their thoughts or ideas supporting their opinions and choosing a conversation topic
