cannot be facilitated properly. The potential ability of the students is limited and cannot develop optimally. The students
‟ having low motivation therefore, will be suitable when textbook teaching material is
applied in their clasroom activity. The students having low motivation tend to be less active and have less abstract thinking than those having high
motivation.
G. Hypotheses
Based on the the theoretical description and rationale above, the hypotheses can be formulated as follows:
1. Computer Based Communication is more effective than Textbook
teaching material to teach writing. 2.
Students with high motivation have better writing skill than studens with low motivation.
3. There is an interaction between teaching material
s and students‟ motivation in teaching writing.

B. Research Method
Research method is a very important factor that ought to be concidered before conducting a research. Nunan 1992:3 states that
research is a systematic process of inquiry consisting of three elements: 1.
A question, problem or hypothesis 2.
Data 3.
Analysis and interpretation of data According to Lerner 1980: 30, the tendency to use
experiments to investigate underlying justworld processes is consistent and claim that carefully controlled experiments are the best
methodology for testing the basic motivational propositions of just- world theory. Experimental research is based on a methodology that
meets three criteria: a random assignment the subjects or other entities are randomly assigned to treatment groups, b experimental
and control group all features of the treatments are identical except for the independent variable i.e., the feature being tested, and c
appropriate measures, the dependent measures are appropriate for testing the research hypothesis.
Experimental research, as postulated by Fraenkel and Wallen 1993: 240, is one of the most powerful research methods researchers
can use. It is claimed as the best way to establish cause-and-effect relationships between variables and directly attempts to influence a
particular variable. Moreover, Christensen 2000: 23 states that
61
through experimentation, cause and effect relationship can be identified. The purpose of experimental study is to investigate the cause and effect
of a certain condition.
Considering the explanation above, related to this study, the
writer used an experimental study because the aim of this study is
revealing the effect of teaching materials and learning motivation towards students‟ writing skill. It involves three kinds of variables.
The first variable is independent variable. In this study, the independent variable is teaching materials. It is also recognized as an
experimental or treatment variable. They are two teaching materials that are used in this study, namely computer based communication teaching
and textbook teaching. Both of these materials are used differently for groups of students at the first semester of Grade XI of SMAN 5
Yogyakarta in the academic year of 20152016. Fraenkel and Wallen 1993: 242 also explain that in the experimental research, it is
important to make comparison group because it serves the purpose of determining whether the treatment has had an effect or whether one
treatment is more effective than another. In this study, the group that received computer based communication is the experimental group and
the group that received textbook material is the control group. The second variable is a dependent variable. The dependent
variable in this study is writing skill of the students at the first semester of Grade XI of SMAN 5 Yogyakarta as the advanced level students. In
