DEVELOPMENT OF LEARNING TOOL OF PHYSICS BASED ON INTERACTIVE MULTIMEDIA CHARGED ON "PROBLEM SOLVING" (MMI-PS) TO INCREASE PROBLEM SOLVING ABILITY FOR PROSPECTIVE TEACHERS

The research aims to develop a product in the form learning tool pf physics based on multi-media interactive
charged on problem solving to improve the thinking ability of prospective teachers. This type of research is the research
development (R & D). Subjects included in the study are experts, professors, and students majoring in physics education FMIPA
Unimed. Data were collected throughvalidation sheet, conducted sheet , questionnaire, and test. Data has been collected were
analyzed descriptively. Learning tool is developed include: lesson plan (RPP) and the Student Worksheet (LKM). The quality of
learning tools in terms of threeaspects, namely validity, practicality, and effectiveness. The validity of the learning tools is based
on the opinion of the validator, the practicality based on implementation and response of lecture and students, and
effectiveness is based on problem solving ability of students. Development of learning tools followed procedure of development
product is a research development in the field of education. Research includes three stages: the stage of defining, the stage of
designing, and the stage of development In this study, the steps being taken onlyto produce the final product and not be
deployed widely.The results showed that the learning tool of Physics has a valid, practically, and effectively.Implementation of
plan of teaching (RPP) has the following characteristics: (1) prepared in accordance with the stageslearning from learning model
increasing thinking ability, (2) develop logical thinking ability of students, (3) oriented contextual physics problems, (4) arranged
in a systematic, (5) Trained studentsin solving physics problems. Student Worksheet (LKM) havecharacteristics: (1) provide an
overview of material coherentl., (2)provides an overview of the learning activities, and (3) includewith the completion of ta sks
/ training.
