CHAPTER III RESEARCH METHODOLOGY AND FINDING
A.
Research Methodology
Method of Research 1. Subject of Research.
The subject of research was the second grade Students of SMP PGRI 12 Jakarta in Pondok Labu. The writer got the data from class VIII-1 and
took 40 students as a sample of the research.
2. Place and Time of Research.
The research of this study was held at SMP PGRI 12 Pondok Labu Jakarta. It was begun by observation and finished by giving the test about
reading from 31 October up to 28
th
November 2008. The writer did the research for four meetings. The research consisted of presenting lesson and
giving test, after data was collected, the writer began to analyze them.
3. Technique of Taking Sample. a. Population
The writer did the research to the second grade Students of SMP PGRI 12 Jakarta that was involved in the process of using contextual teaching
learning for reading skill approach. The reseach populations are the students of SMP PGRI 12 Jakarta.
There are seven parallel class VIII.1 until class VIII.7. The students of the second grade Students were 328 pupils from classes, and the writer took 40
students from one classes VIII-1 as a sample of the research. It was 15 from the total population based on the academic year 20082009. The writer
chose this class VIII-1 because he taught in the class and to make her easier in collecting the data.
b. Sample
The sample was taken by random sampling system namely where 20 students from experiment contextual in english teaching learning process for
reading skill at front of and 20 students from control reading text with skimming and skanning.
4. Technique of Data Collecting.
The technique of data collecting is done by test. The test is done for getting the data objectives of Students achievement in teaching English
reading using Contextual Teaching and learning. The test was given after Teaching and learning process had been finished. The instruments consisted of
30 items test consisting of three types: a. Multiple choice, there are fifteen items and each item is scored 2, so the
total score of this type is 30. b.
True-Falls, there are ten items and each item is scored 3, so the total score of this type is 30.
c. Completion, there are fifth items and each items is scored 4, so the total score of this type is 40.
B.
Research Finding
1. Data Analysis
Data analysis is the last step in the procedure of experiment in this case, data processing. Data processing is the step to know the result of the an
effectiveness by using CTL in teaching reading.
The technique of data analysis used in this research is descriptive analysis percentage, which is described on the table of the percentage. The writer uses
the formula: P = F
× 100 N
P: Percentage F: Frequency
N: Number of sample Mid point X

X maks: Underneath class X min’s: Beneath class
To find out how significance the increase of students’ reading skill using contextual teaching and learning, the writer used a statistical calculation of t-test
to determine the final calculation of t
o
t observation that is done to measure last score of the reseach test.
The formula that used is
2
: t
o
= MD SE
MD
MD = Mean of differences; the average score from the differences gain scores between Y
1
and Y
2
variable, wich are calculating with the formula: MD =
Ʃ D N
Ʃ D = The total score between Y
1
and Y
2
variable, D is gained with the formula: D = Y
