Abstract

The study aimed to determine the effect of the blended learning model on the achievement and improvement of students' mathematical communication in grade XI. The low ability of mathematical communication of high school students is a problem that requires teachers to be able to create and use a new approach in learning. This study uses a quantitative approach with quasi-experimental methods. There were two sample groups in this study, namely the experimental group of 28 students and the control group of 28 students. The sample was randomly selected from the class of SMA Pasundan 2 Cimahi students. The experimental group utilized blended learning model and the control group utilized an ordinary learning model. The instruments used in this study were descriptive and multiple choice tests for mathematical communication. The data obtained were then analyzed using tests for normality, homogeneity, and the difference between the two averages. N-gain data is used to determine the increase in students' mathematical communication. Based on the data analysis, it can be concluded that:  First, the achievement of students' mathematical communication skills who received blended learning was higher than students who received ordinary learning. And Second, the increase in the mathematical communication skills of students utilized blended learning is significantly higher than students utilized ordinary learning.

Abstract

Mathematical literacy helps to understand problems and develop mathematical knowledge to solve various complex problems. However, based on research conducted by the OECD through PISA in 2022, the mathematical literacy skills of Indonesian students are still far below the international average. Purpose of this study was to determine the mathematical literacy abilities of students who received the Connecting, Organizing, Reflecting, Extending (CORE) model with the help of Wordwall compared to students who received conventional learning models. The method used in this research is a quasi-Class with CORE model assisted by Wordwallal method with a nonequivalent Class with Expository modelgroup design. The subjects in this study were eight grader students of SMPN 40 Bandung, the research samples divided into two groups, VIII A as the Class with Expository modelgroup and VIII B as the Class with CORE model assisted by Wordwallal group. Samples taken by purposive technique. In this study, data taken by test of students' mathematical literacy skills conducted before the learning and after the learning treatment. The data obtained were then processed by carrying out a mean difference test with the help of IBM SPSS Statistics 26.0 for Windows. Based on the results of the study, it can be concluded that the mathematical literacy abilities of students who received the Wordwall-assisted CORE model were higher than the mathematical literacy abilities of students who received Expository model.
