Improving the Ability of Mathematic Problem Solving by Learning Management Based Internet Model in Students of Junior High School

Abstract – Ability of mathematic problem solving as one of the extensive orientation of modern mathematic learning will
provide students with other smaller skills that surround them. The skills are creative thinking skill, critical thinking skill,
innovated skill and/or creative problem solving skill. In the globalization era as it is today, the use of learning technology
is present as a media to facilitate students learning independently, especially if the learning time is limited, it has its own
attraction. So the students can improve their own potential in solving mathematic problems. This paper was published
from the results of action research aimed at improving the problem solving skill of Junior High School students by using
Learning Management based internet model. Further, problem solving ability are targeted to be improved refers to
Polya’s theory (1981) : 1) ability to understand the problem; 2) ability to prepare problem solving model; 3) problem
solving ability; 4) ability to re-examine the result of a mathematic problem. This study was tested at Junior High School 2
Parepare for two cycles, and six lessons, and two tests in the end of the cycle. The study results showed that there’s
increasing in problem solving capability based on these steps from first cycle to the second cycle as follows : 1) 68,4% to
90,6%; 2) 56,6% to 88,9%; 3) 49,8% to 84,4%; 4) 30,6% to 53,5%. In addition to the improvement of student’s
mathematic problem solving skill are also accompanied by increased presentation of student’s learning activity by
learning management model based on internet. Besides, 85% of students respond positively to the management learning
model based on internet.
