Abstract

The measure  of success in education is not only assesed on the cognitive side, but also on the character side. Every students must have characters that adheres to the noble values of Indonesia. This  research aims to know applied Problem Based Learning (PBL) model assisted by computer simulation with the increase of students character. This research used quasi experiment methode. The subject of this research involved three groups with each experimental group-1 that applying PBL assisted by computer simulation, the experimental group-2 applying PBL and the control group applying conventional models. The instrument of this study was a obeservation sheets and a questionnairies that measured student’s character.  The character aspects that measured in this research were self-convidence, curiosity, planned, initiative, integrity, perseverance, problem solving, and teamwork. The character’s data analyzed with gain Test (N-gain). The increase percentage of N-gain of student’s character in experiment group 1 and experiment group 2 were 34% and 32%  and respectively in medium category, but in control group, the increase was 12% , in the low category. The highest percentage increase in character of the experimental group 1 and experiment group 2 is the curiosity and the highest percentage increase in character of the control grou percentage increase in character of the is perseverance. Based on the results of the test, the application of pbl assisted by computer simulation is effective in improving student characters.

Abstract

The purpose of this study was to determine the increase of students' critical thinking skills in learning by using Student Worksheets (LKS) assisted by computer simulations. The worksheet used was problem based and contained questions that explore critical thinking skills. This type of research was a quasi experimental of two groups pretest-posttest design. The population of this study was all students of class X Semester I of SMA Negeri 9 Medan, which consisted of seven classes with the number of students was 243 students. The participants of this study consisted of 2 classes which used cluster random sampling technique. The first class was class of X MIA 2, 36 students, as an experimental which was treated by using student worksheets problem-based assisted by computer simulation. The second class was class X MIA 3, 32 students, as a control class which was treated by conventional learning using. The instrument used was a critical thinking test of 10 questions in the form of problem-based description. Based on the results of different tests, this study obtained significant differences on students 'critical thinking skills by using problem-based worksheets assisted by computer simulations. In other words the implementation of learning by using problem-based student worksheets was better in increasing students' critical thinking skills than conventional learning. Percentage increase in N-gain of critical thinking experimental class 64% and control class 43%, respectively - medium category.
