4. Observing monitoring the action The researcher observes all activities in the teaching learning process
while the homeroom teacher helps to create a conducive atmosphere in a class. The researcher also makes collaborative efforts with a collaborator
to explore teaching possibilities. The function of collaborator here is to evaluate the researcher’s teaching, offer suggestion on the best way to
teach, and help to create students motivation to learn English.
5. Reflecting the result of the observation The researcher makes an evaluation on all she has observed to find
the weaknesses of the activities that have been carried out in using experiential learning as the technique in teaching vocabulary.
6. Revising the plan Based on the weakness of the activities that have been carried out in
using experiential learning as the method in teaching vocabulary, the researcher revises the plan for the next cycle.
D. Data Sources
In this research, the researcher uses both quantitative and qualitative data. The quantitative data are in the form of the students’ scores on
vocabulary mastery. The scores are gained through the vocabulary test. In each cycle there is a pretest and post-test for vocabulary mastery. The data
commit to user 47
sources for the quantitative data are the students of the fifth grade of SDN Banaran 01.
The qualitative data are in the form of information about the implementation of experiential learning and students’ reaction to the method
that is used by the researcher as the teacher. Those data are taken from 3 sources, namely:
1. Events which happen in teaching learning process that uses experiential learning method. The events are recorded in the researcher’s and
collaborator’s field notes. 2. Respondents. There are three respondents in this research, they are: the
headmaster, the experienced English teacher, and also the students who join in the class.
3. Document or artifacts. The 2004 National Curriculum for English for Elementary School, syllabus, and lesson plan used by the previous
teachers in teaching learning process.
E. Technique of Collecting the Data
Based on the data and data sources above, the researcher used the following techniques. For the quantitative data the researcher used
vocabulary mastery test, consisting of pre-test and post-test. Every post-test is given after some teaching learning process at the end of a cycle.

The researcher also used what the so called validity and reliability as stated in Ngadiso 2006: 1. The vocabulary test can be seen in Appendix.
The validity of the vocabulary test is analyzed with the following formula:

The item is valid if r

Then to know the reliability of the test, the following formula is used:

Where rkk : estimated reliability
k : number of items on the test
p : the proportion of people who respond correctly to
each item q
: 1 - p s
t 2
: observed score variance The item is reliable if r
o
is higher than r
t
.
There are thirty items tested. The result of vocabulary test is that twenty items are valid and reliable. The valid and reliable items are items
number 1, 2, 3, 4, 6, 7, 9, 10, 11, 13, 15, 17, 18, 21, 23, 25, 27 28, 29 and 30. The items had represented for all indicators, they are five items for
aspect of meaning, ten items for aspect of spelling and pronunciation, and
commit to user 49
five items for aspect of using word. The process and the result of the validity and the reliability of the vocabulary test can be seen in Appendix 7.
Meanwhile, for the qualitative data the researcher used the following techniques:
1. Observation. This technique was done to the teaching and learning process that used experiential learning method. The researcher used
participant observation technique in which the researcher was involved as the teacher and other teacher as the collaborator.
2. Interview. The researcher interviewed some students for the purpose of getting information about their vocabulary improvement after being
taught by using experiential learning method. By using interview, the researcher also found the weakness of the method from the students’
perspective. 3. Questionnaire. The researcher decided to ask the students to fulfill the
questionnaire. Here the students should read the questions and give responses or write in short answers.
