Research Instrument Data Collection .1 Population and Sample

Iman Hilmansyah, 2013 The Use of Video in Teaching Speaking Universitas Pendidikan Indonesia | repository.upi.edu Kranzler and Moursund 1999 proposed that the meaning of null hypothesis is there is no difference between experimental and control classes in the mean adjustment level. So that the null hypothesis in this research is there is no difference between the two groups, experimental and control classes, in students’ speaking ability. 3.2 Data Collection 3.2.1 Population and Sample The population in this research was one of senior high school in Bandung. The total population of first grade students in that school was 168 students which were divided into six classes. The sample used two classes; each class consisted of 25 students. The first was class X-C that was taken as the experimental group and the second was class X-A that was taken as the control group. 25 students from X-C class gave video as a treatment and 25 students from X-A class gave audio tape as a treatment. So the fix number of the sample was 50 students.

3.2.2.1 Test

Oral performance test was used to collect the data of students’ speaking scores. The most important thing in speaking class is that students are able to communicate with other in oral form Jespersen cited in Murcia, 1979: 83. In line with that, oral performance test was chosen as the best way to test speaking ability. In the tests, students have to retell story that was told by the teacher. To get students’ speaking scores, a scoring paper was developed based on the scoring guides proposed by Georgiou Pavlou 2003. The adopted scoring paper consisted of three important aspects which are fluency, pronunciation, and discourse management. The research existed in table 3.1. Table 3.1 Speaking scoring Paper Focus Level √ Score Comments Fluency Frequent and long pauses cause difficulties in communicating. 15 Communicates even though there are some long pauses. 20 Communicates effectively without long pauses. 30 Pronunciation Pronunciaion andor inaccurate intonation makes comprehensio difficult. 15 Acceptable, easily comprehensible pronunciation and intonation. 20 Very good pronnciation and intonation. 30 Discourse Management Structure not correct and there are not connection from each structure 20 Struture correct and there are not connection from each structure 30 Struture correct and there are connection from each structure 40 Overall comments : Action Suggested : Teacher’s signature Adapted from : Georgiou Pavlou, 2003, AssessingYoung Learners, China, Oxford University Press Iman Hilmansyah, 2013 The Use of Video in Teaching Speaking Universitas Pendidikan Indonesia | repository.upi.edu

3.2.2.2 Questionnaire

The questionnaire consisted of several questions related to the students’ feeling about learning speaking, their responses of using video in learning speaking, and students’ view about the use of video. The questionnaire was managed to the experimental group after the post-test. The questions were about students’ responses to the use of video in teaching speaking.
