    Abstract: The purpose of this study is to determine the
effect of discovery learning model with snake ladder
media on the ability of critical thinking and social skills of
students. This type of research includes quasi experiment,
with non-equivalent design (pretest and post-test) control
group design. Technique of data analysis in this research
by using test independent t test. The result of the research
shows that there is significant difference of critical
thinking ability between control and experimental class in
other words there is influence of application of discovery
learning model with snake ladder media to critical
thinking ability in learning process with t<sub>count</sub> = -5,603 and
there is a significant difference of student&#146;s social skill
between control and experiment class in other words the
influence of learning discovery learning model with snake
ladder media on student social skill in learning process
with t<sub>count</sub> = -15,200. It can be concluded that the
discovery learning model with the snake ladder media
significantly influences the critical thinking and social
