1.6 Significances of Research
The significances that expected from the results of this research are: 1.
For teachers, they can enhance the innovative learning model by using Problem Based Learning in Learning tools on teaching and learning process
in the classroom. 2.
For students, they can mastery the concepts in the Human Excretory System topic easier and also can solve any problem about Human Excretory System
in their daily life. 3.
For researcher, especially myself as the teacher candidate can apply the using of Learning tools base Problem Based Learning models in the teaching and
learning process if I had become a teacher, and to know the devastating impact lack of mastery concepts for prospective students.

CHAPTER V CONCLUSSION AND SUGGESTION
5.1. Conclussion
The conclussion of this research are: 1.
Learning achievement of students taught by PBL with individual work is higher than PBL with group work and based on t-test, Ho is rejected and Ha
is received, means that there is a significant differenceof learning achievement between students taught with group and individual work of
Problem Based Learning on Human Excretory System in Grade XI IA SMAN 1 Matauli Academic Year 20122013.
2. Students activitiesof PBL class with individual work is higher than PBL
class with group work and based on t-test, Ho is rejected and Ha is received, means that there is a significant difference of students activitiesbetween
group and individual work of Problem Based Learning on Human Excretory System in Grade XI IA SMAN 1 Matauli Academic Year 20122013.
5.2. Recommendation
Having considered the findings of this research, the suggestions are: 1.
Biologyteacherscan enhance the innovative learning model by using Problem Based Learning which expected to increase students
’ learning achievements and students’ problem solving skill and better to use
Problem Based Learning Model with individual work for more focus on the
student’s ability in solving the problem. 2.
In practice, teachers also need to choose the material according to the approach that will be used in the study so that the desired learning
objectives can be achieved.
