THE EFFECT OF TEACHING TECHNIQUES AND STUDENTS PERSONALITIES ON STUDENTS ACHIEVEMENT IN HORTATORY EXPOSITION WRITING

The objectives of this experimental research were to investigate whether: 1) students achievement in hortatory exposition writing taught by using collaborative writing teaching technique was higher than taught by using clustering teaching technique. 2) students achievement in hortatory exposition writing with extrovert personalities was higher than those with introvert personalities, 3) there was interaction between teaching techniques and personalities on students achievement in hortatory exposition writing. The population of this research was the students in fifth semester of FKIP Nommensen Pematangsiantar 2013/2014 academic year.The total number of population were 280 students. There were 80 students selected as sample of this research by applying cluster random sample technique. The research design was experimental research by using factorial design 2x2. The students were divided into two experimental groups. The experimental group 1 was treated by using collaborative writing teaching technique and experimental group II was treated by using clustering teaching technique. The questionnaire was conducted for classifying the students upon the introvert and extrovert personality. Students achievement in hortatory exposition writing was measured by using writing test. The data were analyzed by applying two-way analysis of variance (ANOVA) at the level of significance α= 0.05. The result reveals that (1) students achievement in hortatory exposition writing taught by using collaborative teaching technique was higher than that taught by using clustering teaching technique, with Fobs= 9,35>Ftab=3.97, (2) students achievement in hortatory exposition writing with extrovert personality was higher than that with introvert personality with Fobs= 4,19>Ftable=3.97, (3) there is interaction between techniques and personality on students achievement in hortatory exposition writing with Fobs=8.20>Ftable=3.97. After computing the Tuckey test, the result showed that extrovert students got higher achievement if they were taught by using collaborative teaching technique while extrovert students got higher achievement if they were taught by using clustering teaching technique.
