assessments can be looked from their skill in writingthat looked specifically from these points of assessing:
a. Content b. Organization
c. Vocabulary d. Language Use
e. Mechanics
7
Those five points are widely used in ESL which is created by Jacobs et.al. The creator differentiates the weight of scoring for every aspect such as
content consist of 30 , organization consist of 20, vocabulary 20, language use consists of 25, and mechanics consists of 5 point out 100.
G. The Technique of Data Analysis
The technique of data analysis used in this experimental research is t- test formula. The use of t-test formula is to examine the hypothesis of the
research after collecting the data in this experimental research. Here are the technique and steps of data analysis:
1. Determining mean of gained score of experimental class M =
Notes:
M : Mean of gained score of experimental class X: The total gained score of students in the experimental class
N: The total students in experimental class 2.
Determining mean of gained score of controlled class =
: Mean of gained score of controlled class

Ibid, p.115.
Y: The total gained score of students in controlled class N: The total students in controlled class
3. Determining of deviation of experimental class =
4. Determining of deviation of controlled class =
5. Determining the t-test After gaining the main gained score and the deviation from each
class, the next step of calculation is determining the t-test, the formula from Arikuntois used as follow:

notes: = Mean of gained score of experiment class
= Mean of gained score of controlled class =The total gained score of students in the experimental class
= The total gained score of students in the controlled class = The total students in the experimental class
= The total students in the controlled class 6. To measure degree of freedom by df =
+ - 2
7. To check the criteria t-table with significance degree 5
