Abstract:
This research aims to know the effectiveness of learning in physics laboratory in improving cognitive
and psychomotor learning result students, grade X SMA Negeri 1 Kerumutan 2011/2012 academic
year on a circuit of direct current subject matter. The research was conducted using posttest-only
control design research that consists of a control class and a class experiment. In this study, class XB
as class experiments with applying the learning in the laboratory and classroom control class with the
XC into conventional learning in the classroom. The research instruments used consisted of learning
devices and instruments of data collection. Data collection techniques using the techniques of tests
(written tests and performance tests).The Data is analyzed using inferensial analysis and descriptive.
Through the analysis of inferensial with t test obtained tcount > ttable or (4,041 > 2,024), so there is a
significant difference to the results of the cognitive learning of physics students in class X SMA
Negeri 1 Kerumutan who apply learning in the laboratory with a class that implements the
conventional learning in class. A descriptive analysis of the results obtained result studied physics
students in classes that implement learning in physics laboratory is higher than the class that
implements the conventional learning in class. Absorption study of cognitive and psychomotor results
are obtained on good category and the effectiveness of learning on effective category. Thus the study
of physics aspects of psychomotor-containing effectively carried out in the laboratory.
