B. Method and Design of the Study
This study uses quantitative method. According to Creswell, quantitative research has several characteristics, one of them is describing a research problem
through a description of trends or a need for an explanation of the relationship among variables. It is also analyzing trends, comparing groups, or relating variable using
statistical analysis and interpreting results by comparing them with prior predictions and past research.

This study used quasi-experimental design with controlled group and experimental group. Quasi-experimental design were used because this study is
an experimental design that does not meet all the requirements necessary for controlling the influence of extraneous variables. In this study, controlled group
means a group who only gets traditional learning like translating or doing exercise without being given some collocations. In contrast, experimental group was presented
some collocations related to the context of procedure text particularly genre of recipes during writing class.
C. Population and Sample
Population is a group of individuals who have the same characteristic that the researcher can identify, whereas sample is a subgroup of the population that the
researcher plans to study. Sample is individuals who are represents the entire population.

students were available for this study which means that the students fulfilled the criteria of this study. It also because the writer had access to the school and had the
permission of the principal to conduct this study. This study will be conducted in two
