APPLICATION OF CONCEPT MAPPING TO INCREASE THE MATHEMATICS STUDENT ACHIEVEMENT IN STOICHOMETRY

Stoichiometry, a material that seemed easy and simple but has a fairly extensive study. The application of the concept map media will allow students to learn and connect concepts with each other in the learning concept stoichiometry and makes learning more meaningful so students. Results of the study proved that learning with concept maps media effectively used in improving student learning outcomes in program mathematics FMIPA UNIMED in following the general chemistry course-I on learning stoichiometry. The average increase in learning outcomes (gain scores) students are given learning with concept maps media (lesson-1 = 0.67±0.20; lesson-2 = 0.68±0.16; lesson-3 = 0.79±0.15; and the overall lesson = 0.71 ± 0.11) higher than the average increase in learning outcomes (gain scores) students are given learning without media concept map (lesson-1 = 0.50±0.20; lesson-2 = 0.58±0.16; lesson-3 = 0.62±0.14; and the overall lesson = 0.57±0.11).
