4. For other researchers:
To be inspiration or comparison to do or develop the similar research.
1.7 Operational Definition
1. Students’ mathematical problem solving ability is the ability of students in
solving problem in mathematics, starting from understanding the problem, devising the plan, carrying out the plan till looking back to the problem.
2. Contextual Teaching and Learning is a kind of instructional that helps
students to understand the significance of the subject matter learned by relating the material to the context of their daily lives and help teachers
relates instructional activities to subjects matter. 3.
Realistic Mathematics Education is a procedure used in discussing mathematics materials that have characteristics using context, model,
students contribution, interactive activities, has related material between guided reinvention and progressive mathematization principles, learning
phenomenon didactical phenomenology and self-developed model.

CHAPTER V CONCLUSION AND SUGGESTION
5.1 Conclusion
Based on the result and discussion of research in the previous chapters, can be concluded that In Hypothesis test, the data are processed based on
difference of pre-test and post-test shows
� �
= 2.878 and
�
= 1.672 then
� � �
that it’s mean H₀ rejected. So, can be concluded that students’ mathematics problem solving ability taught using CTL is higher than
taught using RME.
5.2 Suggestion
Based on the conclusion and relevant study of this research, there are some suggestions as follows:
1. For mathematics teacher, to implement the contextual teaching learning in the
learning activity such that students’ problem solving ability can be increased the students’ problem solving ability.
2. For students, to cooperate with teachers by following the steps of learning
process and don’t ignore the steps of problem solving ability. 3.
For next researcher, to observe another students’ ability of mathematics which can be affected by using contextual teaching learning and another
choices of learning model. 4.
From the research that was held, Contextual Teaching learning should be implemented as the one of the learning model in class and Realistic
Mathematics Education can be implemented too in class as the other source of learning model.
5. Because in this research the learning models are implemented to subject
Program Linear, it is suggested to try another topic of mathematics and relate it to others factor
which may influent students’ learning outcomes.
