Directions : Read the following excerpts and the information about the sources. Then decide whether each student sample uses the source correctly, paying special attention to avoiding plagiarism, having correct in-text citation in MLA documentation style, and integrating the source properly into sentences. If the student has made an error in using the source, write “wrong.” If the student has quoted correctly, write “OK”. Excerpt #2 Effective feedback is immediate, honest, and appropriate. The most effective feedback is immediate. Ideally, feedback is sent immediately after you receive the message. It loses its effectiveness with time. The longer you wait to praise or punish, the less effect it will have. Feedback should be an honest reaction to communication. But feedback should not be merely a series of messages to build up the speaker’s ego. Feedback about your understanding of an agreement with the message should be honest. Do not be afraid to admit you did not understand a message. Nor should you hesitate to disagree. Feedback should be appropriate to the communication situation. Remember, however, the appropriateness is a learned concept. So, what is appropriate in your culture is not necessarily appropriate in another. In the United States, for example, it is considered to appropriate to signal interest in a public speaker by maintaining focused eye contact with the speaker throughout the speech. In Japan, that same interest is signaled by closing one’s eyes to aid concentration. From Smith, Brenda D. Breaking Through. Longman, 1991. The excerpt is from page 180.
