ABSTRACT
Science learning in school can be applied by connecting the material in the learning with real life. However in 
fact science learning process in SMP Negeri 10 Magelang has not emphasized students’ activity to relate science 
to real life. Learning science using CTL guided inquiry-based model implement the learning in where teacher 
provides initial questions related issues or events in everyday life, then students do experiments to prove concepts 
of science guided by teacher.The purpose of this research is to determine the effectiveness the model in topic 
of learning of chemicals in life to improve students’ learning outcomes and activity. This research was a quasi-
experimental research. The research was conducted in SMP Negeri 10 Magelang with 8th grade students as 
research subjects. The sample in this study was taken using purposive sampling technique then resulting VIIIA 
as experiment group and VIIIC as control group. The result shows that experiment group’s learning outcomes 
increased with N-gain value of 0.62 in the medium criteria. Experiment group’s average of learning outcomes is 
higher than control group based on the calculation t test with tcount ≥ ttable (5.42 ≥ 1.67). Experiment group’s 
activity also increased every meeting, first meeting was 36.9% in less active criteria, the second meeting increased 
to be quite active of 60.5%, the third meeting was in the active criteria of 78.2%, and the fourth meeting was 
81.4% in very active criteria. It can be concluded that the CTL guided inquiry-based model is effective to improve 
students’ learning outcomes and activity.
