The Effect of Teaching Strategies and Students’ Interest on the Students’ Speaking Achievement

The aims of this research were to define whether: 1) students’ speaking achievement
higher taught by using IOC or NHT strategy, 2) for high interest students higher
taught by using IOC or NHT strategy, 3) for low interest students higher taught by
using IOC or NHT strategy, 4) there were interactions between teaching strategies
and students’ interest. The XI Grade of SMA Swasta Sinar Husni was the population
in this research. There were 4 classes and there 36 students each class. Two classes
which consisted of 72 students became the sample. This research used experimental
research. The XI Science-1was taught by using the IOC Strategy and the XI Science�2 was taught by using NHT strategy. The Questionnaire was administrated for
classifying the interest of the students’ speaking achievement. Students’ speaking
achievement test was measured by using dialogue between two students. The data
were analysed by applying two-way analysis of variance (ANOVA) at the level of
significance α = 0.05. The result of data analysis proved that; 1) Students’ speaking
achievement taught by using IOC strategy was higher than taught by using NHT
strategy, 2) Students’ speaking achievement with high interest higher taught by using
IOC strategy than taught by using NHT strategy, 3) For low interest students higher
taught by using IOC than NHT strategy, 4) There was interaction between teaching
strategies and students’ interest, with 24.73 > 0.05. Moreover, Scheffe – Test result
also showed that the students’ interest got better achievement if they were taught by
using Inside-Outside Circle strategy
