te process of problem based experiment where they are able to apply the concept of knowledge with real situation.
This research is aimed to study the implementation of problem based experiment as the effo
rt to improve students’ problem solving skills. In this study, the implementation will be implemented to secondary level students of 8
th
Grade in the concept of separation method. Concept determination is reconsidered based on
characteristic analysis of the concept where it is contextually related with daily life. This concept is compatible with the characteristic of problem based learning which
the problem comes from daily activity and familiar condition that usually faced by students.
B. Research problem
In line with the explanatory backround that has been described, problem that rose in this research is stated in the following question:
“How is the improvement of students’ problem solving skills in the concept of separation method by using problem based
experiment?”
1. Research Question
Elaborating the research problem above, the research
attempts to explore the following questions
: a.
How is the improvement of students’ problem solving skill in domain of problem analysis, problem solving planning, and problem solving evaluating?
b. How is the improvement of students’ problem solving skill in domain of problem
solving planning?

c. How is the improvement of students’ problem solving skills in domain of
conducting problem solving? d.
How is the improvement of students’ problem solving skill in domain of problem solving evaluation?
2. Research Scope
The problem stated is limited to the aspects a follows: a.
Problem solving skills which is examined in this research refers to problem solving skills domain proposed by Mettes et. Al 1981 included problem
analysis, problem solving planning, conducting problem solving, and evaluating problem solving.
b. The concept of separation method which is described is limited to the indicator
arranged in Cambridge curriculum for secondary two students.
C. Research Objectives
This research is aimed to investigate the improvement of students’ problem
solving skills as the result of problem based experiment Implementation in the concept of separation method.
D. The Significance of Research
This research is beneficial in giving alternative method to improve problem solving skill during science instruction.

CHAPTER III METHODOLOGY
A.
Location and Research Subject
This research is conducted at one of private school in Bandung which is implementing Cambridge Curriculum. The school is determined based on
consideration where the school is regularly dealing with curriculum reflecting problem solving skills in its structure.
Moreover, the subject of research is 16 students of secondary 2 in high achiever class. Sampling technique of research subject is determined by using
purposive sampling. Accordingly, educational research is often utilized quota purposive sampling in difficulty to take probability McMillan, 2012. Yet, High
Achiever Class is taken as the consideration f rom preliminary study where student’s
cognitive achievement is excell as the effort to prevent cognitive load during the implementation.
B. Research Method
Research method used in this research is descriptive quantitative as the purpose if the research is appropriate with this method. Descriptive quantitative
method is utilized to describe the phenomena or the condition of certain variables Arikunto, 2002.
C. Operational Definition
