Improving the Quality of Science Learning in Sound Energy Materials through the Application of Experimental Scientific Learning Models in Class IV of SD Inpres Perumnas

The main factors in the success of science teaching are required to have professional knowledge and abilities in choosing and using appropriate learning methods and models according to the characteristics of students in delivering teaching materials well, so that learning objectives can be achieved. This study aims to describe the application of scientific learning models based on experimental methods to improve the quality of science learning outcomes in sound energy material in the fourth grade of SD Inpres Perumnas. The study method was a classroom action research. The research subjects were 25 students, consisting of 10 male students and 15 female students. The data collection technique was observation and test techniques. Data analysis was carried out by analyzing data qualitatively and quantitatively. The results of the study showed an increase in teacher activity and student activities. The activity of students in the first cycle is 70.45% or sufficient, increasing in the second cycle to 89.77% or very good. Teacher activity in the first cycle was 70.83% or good, and increased in the cycle to 91.67% or very good. Classical absorption (DSK) cycle I was 57.5% in the second cycle to 77.5%. Classical learning completeness (KBK) of the first cycle of 66% increased in the second cycle to 86%. Based on these results, it was concluded that the application of the scientific approach based on the experimental method improved the quality of science learning in the fourth grade of SD Inpres Perumnas
