THE INFLUENCE OF SELF-DIRECTED DIALOGUE TO THE SECOND GRADE STUDENTS’ SPEAKING ABILITY

Abstract

The purpose of this research was to investigate the effectiveness of using Self-directed
Dialogue Technique in improving the second grade students’ speaking ability of SMP Negeri 2
Palasa. The quasi-experimental research design was used by involving experimental and
control groups. The research samples were VIII A as the experimental group with 19 students
and VIII B as the control group with 20 students selected by purposive sampling technique. In
collecting the data, the researcher gave pre-test and post-test to both experimental and control
groups. The treatment was given only to the experimental group. The data were analyzed
statistically in order to find out the significant difference of students’ achievement in pre-test
and post-test. The mean score of pre-test of the experimental group was 43.8 while the control
group was 37.4. The mean score of the post-test of experimental group was 64.04 while the
control group was 51.6. By using the 0.05 level of significance and 37 as the degree of freedom
(df) = Nx + Ny – 2 = 20 + 19 – 2 = 37, the researcher computed the data and found that the
value of the t-counted (2.73) was higher than the t-table (2.02). It means that the hypothesis is
accepted. In other words, using self-directed dialogue technique can influence the students’
