Abstract :
The low ability of mathematical connection of students is caused by the learning
process by giving the concept directly and rarely there is the application of the
subject matter with the daily life of the students. Discovery Learning model is a
solution offered to overcome the problem of low mathematical connection ability
of students. This research has a purpose to see whether there is influence of
learning model of Discovery Learning on mathematical connection ability of class
VII students of SMP Muhammadiyah Rambah. This type of research is quasi
experimental research (Quasi Eksperimen) with Two-Group Posttest Only
research design. The population in this study is the seventh grade students of SMP
Muhammadiyah Rambah. Sampling using Simple Random Sampling technique, so
that obtained class VII 2 as experiment class and class VII 1 as control class. In
the experimental class conducted learning model Discovery Learning, while the
control class is done conventional learning. Data of mathematical connection
capability was obtained by using test technique. The test is given at the end of the
learning with the instrument is a matter of mathematical connection ability test
that has been done validity analysis, difficulty level, distinguishing power and
reliability. Data analysis was performed for hypothesis testing. Before the first
hypothesis test is done prerequisite test is the normality test. Based on the
prerequisite test results obtained that the data is not normally distributed, thus
testing the hypothesis done by Mann Whitney test. The calculation result is
obtained that zcount ? ztabel is 12,86 > 1,96 with value in the degree of significance
was 0,05, then reject H0. So it can be concluded that there is influence of learning
model of Discovery Learning to ability of mathematical connection of student of
class VII SMP Muhammadiyah Rambah.
