C. Research Instruments
In order to obtain the reliable and valid data, this research made use of five instruments namely observation sheet, interview list, questionnaire, interviews
and recorder. The observation sheet see Appendix 2 contained some points about what to be observed. The writer attempted to discover any information
about the Microteaching Class related to how and when the lecturers gave feedback to the Microteaching students.
The second instrument employed in this research was interview list. The list see Appendix 6 contained some questions that should be answered orally. The
questions were designed from the simple to the complex questions to find out further information about Microteaching students’ perception on the feedback.
Another instrument used was questionnaire. The questionnaire see Appendix 4 contained some statements related to how students perceived feedback from the
lecturers, whether the feedback improved their second performance in Microteaching Class and their comments and suggestions for the lecturers on how
feedback should be given to help the students improve their performance. The questionnaire consisted of two different parts. The first part was close-ended
questions which consisted of a set of statements with the five optional answers in a form of the degree of agreement of strongly agree, agree, neutral, disagree,
strongly disagree that students could choose. The second part was the open-ended questions which were a set of question where they could give their opinion and
suggestion about the way the lecturer gives feedback.

For the interview, the writer employed a recorder to record all the spoken data from the participants when they were answering the questions stated in the
interview list. In addition to that, the writer also made use of video recording of students’ teaching performance to observe their improvement.
D. Data Gathering Technique
Having the research instruments, the writer employed some techniques to obtain the data needed. The first was doing observation on three selected
Microteaching Classes. Those observations were aimed at discovering what the feedback that the lecturer gave to the students is. In the observations, the writer
used the observation sheet as a guideline of what data was needed. The observations were done on May 11

2010, on weekly meeting of each Microteaching class. The next step was distributing questionnaire to discover their perception on
the lecturer’s feedback in improving their teaching performance in Microteaching Class and their suggestion for the lecturers in giving feedback to the students. The
questionnaire was distributed on May 6
th
, 7
th
, and 14
th
2010. It was on their last meeting of Microteaching Class when all of the students had their second class
teaching practice. The students did not fill the questionnaire in class but the writer asked the students to bring it home because of some reasons. The first reason was
they were exhausted mentally and physically since the class ended at 4 or 6 P.M. and that Microteaching was the last course they had in a day. The second reason
27
was they would have some times to think to answer the questions in the questionnaire. Hence, they could provide the best answer they could give.
The writer had an interview with nine students on May 17
th
– 26
th
2010. Before having the interview, the writer analyzed the questionnaire filled by those
nine students. The writer did the interview to get their deeper perception about the feedback and their teaching performance after having the feedback. Afterward, to
see whether there was an improvement on their teaching performance and to check the result of the interview, the writer observed video recordings of three
students’ performance of their progress test 1 and final test. The writer compared the first and the second video to see the improvement.
