E. Technique of Collecting Data
Data are absolute requirement of a research as it is a means of proving hypothesis. Data are used to either solve or answer the problem of the
research. In order to get the appropriate data, data must be collected by using appropriate technique. According to Arikunto 2002: 127, there are some
techniques of collecting the data, namely: test, questionnaire, interview, observation, rating scale, and documentation.
In this research, the researcher used an instrument to collect the research data. It was through writing test and verbal creativity test. The
writing test was used to collect data of students’ writing skill while the other test
was used to collect data of students’ creativity level. The writing test was used to collect data related to the students’ writing
skill improvements after the treatment was given. The writing test was given in a form of essay. The scoring is based on indicators of writing competence:
organization, content, grammarlanguage use, vocabulary, and mechanics.
Before administering the test, it was important to examine the readability of the both tests. Readability is the ease in which text can be read
and understood. It means that in administering a test, the test has to set in understandable instructions. If the test is tested to some students out of the
sample group, they will understand the instructions of the test and do as the instruction asked them to do. In other word, the instruction of the writing and
creativity test should be clear and easy to understand. The readability was measured by using some questions. The questions for the instruction in
writing test were as follow: 1
Whether the instruction is understandable or not; 2
Whether the kind of the text to be written is clear or not; 3
Whether there is difficult words in the instruction or not; 4
Whether the words should be written is clearly stated or not; 5
Whether the writing indicators to be evaluated are clear or not; and 6
Whether the time provided is enough or not. Moreover, in this research, inter rater was used to avoid subjectivity in
scoring the students’ writing. Scoring by using inter rater means there are two different scorers.
