ABSTRACT
The purpose of this research were to know the effect of character

education implementation toward improvement of students curiosity and critical
thinking ability in Physics (Newton Laws).The research method was quasi
experimental. The population were all of students grade VIII SMP Swasta
Muhammadiyah I Medan and 80 students became sample of this research. The
sample divided into two classes, experimental and control classes. The treatment
given was the implementation of character education in class VIII-C use inquiry
learning, and without the implementation of character education in class VIII-B.
Data obtained by direct observation for the students curiosity and test of critical
thinking ability after learning that the treatment given. Data analysis technique
used is the chi-square.
To get data of curiosity variable using observation sheet that suitable
indicator of person that has curiosity, while to get data of critical thinking using
essay test. Instrument validation of this research tested by using content
validation. Data analysis technique used two way ANOVA and processed by
SPSS 16.0.Then significant level that used α = 0.05.
The results of first hypothesis get sig 0.000, 0.05 > sig 0.000,so first
hypothesis Ha is received, therefore there is difference of critical thinking ability
with character education implementation using Inquiry Learning and Inquiry
Learning without character education.. Then, second hypothesis get sig 0.001,
0.05 > sig 0.000,so second hypothesis Ha is received, therefore there is the

difference of critical thinking ability between students that have high curiosity and
low curiosity.Third hypothesis get sig 0.159, 0.05
