EFEKTIVITAS MODEL GUIDED DISCOVERY LEARNING UNTUK VIDEO PEMBELAJARAN DALAM MENGETAHUI PERBEDAAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA

The purpose of this study is to find out whether there is a difference between students' mathematical problem solving skills in guided discovery learning lessons for learning videos and conventional models, whether the problem solving skills of mathematics students using guided discovery learning model for video learning better than students using conventional learning model. whether the mathematical problem solving ability of students who dierikan treatment to complete thoroughly both classical and individual. The sampling technique used is cluster random sampling selected class XI Accounting 1 given treatment and class XI Marketing 2 given conventional model. Data collection techniques used are test methods and non-test methods. Based on the prerequisite test it was concluded that the samples were normally distributed, had the same variance, and had the same initial ability. The result of the research is there is difference of mean of problem solving ability of student mathematics using learning of guided discovery learning model for conventional learning and learning video, guided discovery learning model for video learning better than conventional learning to problem solving ability and problem solving ability of student mathematics using guided discovery learning model for learning video to complete a classical that is said to be complete if at least 85% of students thoroughly learn individually from the number of students in one class, while solved individually that is the ability of solving mathematical problems students reach an average of more than 75.
