experiment uses two groups in which experimental group as a group that is given a treatment and the controlled group that is not given a treatment in order to know
difference between the “new” method and the mostly teaching method.

This research was done to the students from two classes that have the same level. They were given different teaching approaches. Each class consisted of 38
students. The first class which was as experimental class was given reading comprehension of narrative text by using Directed Reading
– Thinking Activity DR-TA strategy; DR-TA strategy was the treatment
or “new” method. At the same time, the second class
– controlled class – was given reading comprehension of narrative text by the method which was mostly used by the teacher to teach
reading. This research was focused on giving treatment to the experimental class by
applying DR-TA strategy to measure students’ achievement and to find out the
influence of DR-TA strategy on students’ reading comprehension of narrative
text. Then, the results from reading test were calculated.

C. Population and Sample
The population of the research was the tenth grade students of SMA Negeri 10 Kota Tangerang Selatan. There were 7 classes of the tenth grade. The total
number of students or population was 266 students. Meanwhile, the sampling technique used for this research was purposive
sampling because this research took the sample with any consideration. This research was conducted to X.5 class as the experimental class and X.6 class as the
controlled class because of the suggestion of the English teacher in that school. The teacher said that the two classes had the same level, and they were
appropriate to be the sample of the research. In other words, purposive sampling was used because both classes were considered as knowledgeable and informative
so that those classes were able to be the sample of this research. This research was conducted to those two classes in order to see whether the given treatment in
experimental class gives influence on students’ reading comprehension of
narrative text or not.
D. Instrument of the Research
The instrument of this research was a reading test of English consisted of 40 multiple choice questions taken from some books of English for the tenth
grade students of senior high school. The test that will be given to the students in experimental and controlled class must be valid and reliable so that the 40
questions had been tested first to the students from other class in order to measure the test
’s validity and reliability by using AnatestV4. From the ANAVA result, only 25 questions were chosen divided into 3 difficult questions, 1 easy question
and 21 intermediate questions because those were valid and reliable questions for further explanation can be seen on appendices.
E. Data Collection Technique
In collecting the data, pretest and posttest consisting of 25 questions in multiple choice forms were given to the students. This type was chosen because it
was common test model which is usually used by many researchers in conducting
