THE INFLUENCE OF THREE STAGE FISHBOWL DECISION STRATEGY ON STUDENTS’ MATHEMATICAL PROBLEM SOLVING ABILITY

This research has a purpose to know whether the influence of three stage fishbowl decision on students’ mathematical problem solving ability in learning process. This type of research is a pseudo experiment by determining one class which take randomly as a sample as an experiment class. The problem in this research is the students' mathematic problem solving ability. The population is all the 8th students at junior high School 3 Lintongnihuta which consist of 6 classes with the total number of 180 students. The sample of the research is VIII-1 class with the total number of 30 students. The technique of data collection is conducted through an observation to observe student activities and a test to measure skills, intelligence knowledge, abilities or talents possessed by individuals or groups. Determining the result of mathematical problem solving ability of students, it uses statistical test. The result of research indicates that learning strategy of three stage of fishbowl decision have influence to student's mathematical problem solving ability equal to 35,77 % while the rest 64,23 % influenced by other factor.
