Improving Student’s Mathematical Connection Ability Through Project Based Learning

Abstract

The purpose of this study was to improve the mathematical connection of statistics material through Project Based Learning with the Teaching at the Right Level (TaRL) approach in 4th grade students totaling 18 children. This research method is a classroom action research model of Kemmis and Mc. Taggart model. Each cycle consists of planning, action, observation, and reflection. Data collection techniques used observation, tests, documentation, and interviews. The performance indicator set is that at the end of the cycle 75% of the number of grade 4 students have mathematical connection skills in the good category with a minimum score of 70. The conclusion obtained from the research is that the Project Based Learning (PjBL) model can improve mathematical connection skills in grade 4 students. This is shown through the results of initial observations, students have mathematical connection skills with an average score of 61 in the sufficient category. After the implementation of cycle 1 action, the average score of mathematical connection ability increased to 68 although it was still in the sufficient category. In cycle 2, the math connection ability score again increased to 75 and was included in the good category.
