The researcher used quantitative method to analyse the result of the research. Quantitative method was
used to analyse the result of students’ speaking achievement. The researcher used two groups pre test and post test designs
because the researcher wanted to investigate which one between these two methods had more effective result
for students’ achievement in learning speaking.
The research design of two group pre-test and post-test designs is illustrated as follows:

There were two variables in this research i.e. dependent variable and independent variable. The dependent
variable is students’ speaking skill. The independent
variable are two methods that were used as treatment in teaching speaking for the student. The data was about the
students’ speaking achievement which can be used to identify which one is better between power teaching and CTL method.
3.2. Population and Sample
This research was conducted at SMAN 10 Bandar Lampung, at second semester of the first grade 20142015. The population is the first year student of SMAN 10
Bandar Lampung. The samples were eleven grade students. The researcher took 2 classes from 10 classes randomly as the sample. There are 32 students in a class.
Their ages range from 14 to 16 years old. The researcher took two classes as the sample, and the researcher teach them by these two methods to see students’
response or students’ participation in speaking class. The researcher compared between two methods to know the better method in speaking class between Power
Teaching and CTL. This research focused on the improvement of students’
speaking skill.
3.3. Variables
This research consists of the following variables: a. Students’ speaking ability as dependent variable Y
b. Power Teaching as independent variable X1 c. CTL method as independent variable X2
3.4. Data Collecting Techniques
In collecting the data, the researcher used two techniques as follows:
1 Pre-test
The researcher administered pre-test before treatment, which lasted 90 minutes. It was aimed at knowing
the students’ speaking ability before being given the treatment using Power Teaching method and CTL method. This test was given to
both classes. In pre-test the researcher provided some topics to the students and gave five minutes before the students made a monologue based on the topic and
their knowledge. So, they must speak individually. The material for pre-test or post-test were taken from their own student book. The form of the test was
subjective test, because there was no exact answer. The aspects of speaking evaluated in this test were pronunciation, fluency, vocabulary, comprehension,
and grammar. The pre-test was similar to the post-test.
2 Post-test
The researcher gave the post-test to the students after the treatment. It aimed to investigate the effect of Power Teaching and CTL method on speaking ability
after applying Power Teaching and CTL method. The procedure, the type, and the duration were similar to the pre-test.
3.5. Research Procedures
The procedure of this research is as follows:
