Rese Resear arch ch Des Desi% i%" " This research used a true experimental design in Pretest-Posttest Control Group tpe. Through this tpe of design! the two randomi"ed sub#ects! experimental and control groups! were given a pre-test and post test. The pre-test was given in order to investigate whether there were significant differences between the experimental and control group. $owever! after the pre-test! the experimental group were given treatment through teaching using . . . method; while the control group were not. The effect of the treatment was seen using the form% (&'  &)  (&*  &+). The design of research can be illustrated as follows% Group ( ) ( )

The sampling of this research used random sampling techni1ue. andom sampling can be defined as a techni1ue of sampling without considering the strata of the members due to the fact that the members (respondents) of this research were categori"ed homogeneous.

The validit test used 7product moment correlation8 techni1ues. Then! the result (r-product) was compared to the r-table (. . .) in significance level 9.9:. f r-product is greater than the r-table! the items of  the instrument are valid; and in verse.  3n instrument is reliable if the instrument is consistent in measuring what is measured. n this research the reliabilit test used Cronbach Alpha coefficient using the SPSS Version . . . for Windows. 3n instrument is reliable when < r-table. ˃

G. Data A"a!,sis Tech"i)'e  3nal"ing data is an important stage in a research. 3fter data are collected! the data should be anal"ed using a techni1ue concerned with the research method. 2ince this research was 1uantitative (experimental)! the researcher used the 1ualitative (descriptive statistics) and 1uantitative analsis (3nalsis of ariance =3>?3@) techni1ues. ,escriptive techni1ue is used to describe the sub#ects through the sample. n this research the descriptive techni1ues was used to describe the tendenc of the respondents towards the independent variable concerned with the implementation of method . . . in teaching . . . to students . . . .  3>?3! in this case two wa 3>?3 was used to test the hpothesis.
