Teachers need a briliant idea to be extremely mindful of student self-perceptions and those of their peers. A few tips may be helpful: all students need some helps
in some area; if students have a strong willingness to try something new everyday, students will significantly improve their reading; note students own progress and
see what they have learnt in their class everyday. Based on the explanation above, I try to conclude that the characteristic of
Junior High School students is similar to children who like to imitate whatever they see and listen especially from adult like parents and teachers. Related to the
characteristic of students, the method of teaching that is appropriate for them is CLL. It is appropriate because CLL applies an interesting way in teaching.
2.6 Experimental Research Theory
The experimental research is a systematic and scientific approach of research in which the researcher manipulates one or more variables, and controls and
measures any change in other variables. According to Fraenkel and Wallen 1993: 241, “experimental research is unique in two very important respects: it is the
only type of research that directly attempts to influence a particular variable and it is the only type that can really test hypotheses about cause and effect
relationship.” Gall 2003:366 adds that it represents the most valid approach to the solution of educational problems, both practical and theoretical, and to the
advancement of education as science. It means that, I can manipulate the independent variable in an experimental research. I, as the writer is the one who
absolutely arranged and decided the nature of the treatment, what is going to
happen to the subject of the study and to whom it is to be appropriate length of time. As Gall 2003:366 says, “in experimental study, the writer manipulates at
least one independent variable, controls relevant variables and observes the effect on one or more dependent variables.” Therefore, in this reserach there are various
designs of the experimental design, such as pre-experimental design, quasi experimental design, and true experimental design. I choose pre-experimental
study as my research design in my research. Hartoyo 2009:31 states that, “Pre-experimental design is a design which a
single group is often studied but no comparison between an equivalent non- treatment
group is made.” In this pre-experimental design, there are four designs; those are the one-shot case study, one group pre-test and post-test experimental
design, experimental and control groups post test only design, and two experimental groups post test only design. One of the designs I use in my study is
one group pre-test and post-test experimental design. There is a benefit in this design as stated by Heffiner that is the inclusion of a pre-test to determine baseline
scores. Whereas, the aim of this design is to evaluate the influence of a variable Leedy, 1997: 232-233.
The first step using this design is by giving a pre-test to one group, conducting a treatment using CLL method for about twice in my second treatment, and the
last is a post-test. One group pre-test post-test design itself is designed only using one group. Besides, there is no control group or comparison group used in this
study.
