THE DEVELOPMENT OF INNOVATIVE AND INTERACTIVE LEARNING MATERIAL IN MULTIMEDIA BASED ON THE TEACHING OF BUFFER SOLUTION

The development and innovation of learning material based multimedia in
buffer solution was done to help student in learning . The study is aimed to obtain
a good and standart learning material in buffer solution which can improve the
student learning outcomes and student motivation to learn. The study was
conducted through the development,innovation,integration of learning and
multimedia on buffer solution and then trial and implementation of the learning
material to the student. The material is then designed in printed and electronic
basesThe population of this study was all of the students in grade XI senior high
school. The research sample was taken from SMAN 1 Berastagi, SMAN 1
Kabanjahe, and SMAN 2 Kabanjahe which consist of two classes, the
experimental class and control class. The experiment class learn by using the
developed and innovated learning material based multimedia, while the control
class learn by using chemistry handbook. The results show that : (1) the chemistry
books about buffer solution that were analyzed have an average of assesment
3.27, (2) the component which are integrated into develop learning material were
the integration of relevant laboratory experiment, application, pictures, problems
and examples, sets of evaluation and key answer, and macromedia flash. The
integration of multimedia done by make the developed learning material to be an
e-book that created using the flip book maker software, (3) the assessment result
from the expert validator toward the developed learning material is 4.27and the
standarization result from student is 4.1 (4)Innovated learning material is very
effective to improve students achievement in chemistry. Students achievement in
experimental class which were taught by innovated textbook is higher than control
class that are taught by ordinary references with tcount > ttable (4.586 > 1.654). (5)
The student motivation in using the interactive learning material based multimedia
gotten the percentage is 76% means that the motivaton in category of very good.
