THE DEVELOPMENT OF INNOVATIVE TEACHING MATERIALS BASED ON MULTIMEDIA TO IMPROVE STUDENT LEARNING OUTCOMES OF SOLUBILITY AND SOLUBILITY PRODUCT MATERIALS

The development of innovative teaching materials based on multimedia need attention in fulfill demands to
improving the quality of education and increase the efficiency and effectiveness of learning towards reform in order to
achieve good learning outcomes. This research aimed to obtain innovative teaching materials based on multimedia of
solubility and solubility product materials which can improve student learning outcomes. The population in the research
were all students of the State University of Medan. The selection of the sample using purposive sampling technique. The
samples in the research amounted 79 students who are studying subjects of General Chemistry II at the State University
of Medan, which consists of two classes, the experiment and control classes. Experiment class using innovative teaching
materials that have been developed while the control class using general chemistry books owned by the student. Validator
to innovative teaching materials that have been developed consist six lecturers from the State University of Medan and
Islamic University of North Sumatera. The results showed that: (1) the results of the lecturers assessment to innovative
teaching materials that have been developed are 4.25 which mean very valid (very worthy) and do not need revision and
the result of the lecturers assessment to multimedia that have been developed are 4.15 which mean valid (worthy) and
does not need revision, (2) Enhancemet of student learning outcomes who use innovative teaching materials based on
multimedia of solubility and solubility product materials was higher than the enhancement of student learning outcomes
who use general chemistry books owned by the student with tcount> ttable (2.407>1.99).
