The Effectiveness of Blended Learning on Students' Mathematical Problem Solving Ability

Abstract

Problem solving ability is one of the objectives of learning mathematics mandated by the 2013 curriculum until the independent learning curriculum. This ability is an important ability to equip students in dealing with ever-changing situations. The importance of this ability is inversely proportional to the low mathematical problem solving ability of class VIII students at SMP Negeri 13 Bandar Lampung. The existing conditions are caused by the application of learning models that have not been able to hone these abilities to the maximum. Therefore, this research aims to determine the effectiveness of the application of Blended Learning on students' mathematical problem solving abilities. This research is a quasi-experimental design with a nonequivalent control group design. The research sample was determined by using a cluster random sampling technique, because the population was homogeneous, with class VIII.1 as the experimental class and class VIII.3 as the control class with 23 and 27 students respectively. Students' mathematical problem solving ability is measured by a test in the form of an essay as many as 5 questions which have been tested for validity and reliability. Hypothesis testing using t test and continued with relative efficiency test in order to see the effectiveness of the model with the distribution of abilities in both classes. The results showed that Blended Learning proved to be effective on the mathematical problem solving abilities of even semester VIII students at SMP Negeri 13 Bandar Lampung in the academic year 2021/2022.
