Abstract


This study aims to describe the effectiveness of Student Worksheets with Problem Solving Model in Exercising Student Reasoning on Pressure Materials through pretest and posttest. The type of research refers to the One Group Pre-test Post-test Design research design. The developed worksheets apply three pressure fields, namely hydrostatic pressure, pascal law and archimedes law. The results of effectiveness in training students reasoning can be seen through increasing student n-gain and reasoning indicators. There are two reasoning indicators that experience an increase in medium category gain and two other indicators in the high category. The indicator explains the relationship between the elements of the problem has a medium category with a gain score of 0.54, the indicator plans and constructs arguments has a high category with a score of 0.75, the indicator composes and checks the correctness of the guesses in the medium category with a score of 0.69 and indicator of ability to draw conclusions in a high category with a score of 0.78. Based on the results of the study it can be concluded that Student Worksheets with Problem Solving Model are effectively used as learning tools in training students reasoning
