THE IMPLEMENTATION OF CONTEXTUAL TEACHING AND LEARNING TO IMPROVE THE ABILITY OF TENTH GRADE STUDENTS OF SMAN 1 SINDUE TOMBUSABORA IN WRITING PROCEDURE TEXT

The objective of this research was to prove whether Contextual Teaching
and Learning (CTL) approach can improve the students‟ ability in writing
procedure text or not. This research applied pre-experimental research design by
using one-group pretest posttest design. The population of this research was the
tenth grade students of SMAN 1 Sindue Tombusabora, and the sample was XB
consisting of 23 students selected by using purposive sampling technique. Then,
the researcher used writing test as an instrument to collect the data. The test was
divided into two parts: pretest and posttest. The pretest was used to measure the
students‟ ability in writing a paragraph of procedure text before treatment, and
posttest was used to measure the students‟ ability after the treatment. The data
were analyzed statistically in order to know the significant difference of the
students‟ achievement in pretest and posttest. The result of data analysis showed
that the mean score was increased significantly from 62 in pretest and 77.3 in
posttest. Moreover, by applying 0.05 level of significance and the degree of
freedom (df) was 22 (df = 23–1=22), the researcher found that the value of tcounted was higher than the value of t-table (4.34 > 1.717). It means that the
hypothesis is accepted. It implies that the implementation of Contextual Teaching
and Learning approach is affective to improve the ability of tenth grade students
of SMAN 1 Sindue Tombusabora in writing procedure text.
