Implementation of A Blended Learning Model Based on Google Classroom on Class XII TKJ Data-Centering Size Material (Case study at SMK Bina Nusa Slawi Student Year 2021/2022)

Related to the role of teachers as learning agents, teachers are required to be able to provide optimal learning by using various learning methods and models that are adapted to the characteristics of students. One of the learning models that can be an alternative solution in learning during a pandemic situation is Blended Learning. The Blended Learning learning model is effective learning and can also be applied to anyone, one of which is those who have difficulty for face-to-face learning continuously. One of the right applications to use in learning using Blended Learning is google classroom. The purpose of this study is to find out that the Google Classroom-based Blended Learning Model can improve mathematics learning outcomes on data centering size materials and to find out whether there are differences between students who are applied google classroom-based blended learning to conventional learning. Based on the results of data analysis, it shows that there is a significant increase between pretest and postest using a google classroom-based blended learning model. The difference is shown by the average pretest value of 68,973 and posttest of 84,865.
