problems. The selected population was Microteaching students who were taking Microteaching course in even semester of 2012. They were ELESP students of
year 2009 that have experienced reinforcement as a teaching skill. Since this is a survey research, the researcher drew a sample for the representatives rather than
used the population, as stated by Fraenkel and Wallen 2009. There were 108 members in the population. The researcher chose the sample randomly because
the members have an equal chance of being selected Fraenkel Wallen, 2009. The participants were listed from number 1 to 108. There were 54 participants

C. Research Participants
The research certainly demanded participants to obtain the information needed. The participants in this research were the students of Microteaching class
in English Language Education Study Program of Sanata Dharma University from year 2009 who were taking the course in even semester of 2012. The logical
reason for choosing them as the participants was because they have experienced the process of teaching practice. They have learnt how to teach for professional
and master the teaching skills especially reinforcement skill as the focus of the research. There were 7 classes to be surveyed, from class A to G. There were 145
students but only 108 participants who returned the questionnaires. Several questionnaires did not fulfill the criteria to be analyzed because of the broken
incomplete pages and incomplete responses also comments for each question. For the need of analysis, the researcher needed samples as the representatives of
the population. The samples were 54 participants as stated in the research method. After having the result of the questionnaire, the researcher chose 19
participants for the focused group discussion. It is to gain more information that was not provided in the questionnaire. The researcher chose those participants
based on their responses in the questionnaire both negative and positive response. They were as the representatives of each Microteaching class.
