Virtual Laboratory and Its Effect on Student Learning Outcomes in Physics Education

Abstract

This study aims to determine the effect of using a virtual laboratory on student learning outcomes in Kirchhoff's law material at the physics education study program at HKBP Nommensen Pematangsiantar T.A. 2020/2021 by utilizing a virtual laboratory. This type of research is a true experiment with the research sample, namely the physics education study program group A as the experimental class and group B as the control class. The research instrument test was composed of 20 multiple-choice questions, the content validity was tested by a team of experts as validators as many as 2 people and student activity observation sheets. From the data analysis, the average post-test value for the experimental class was 78.46 with a standard deviation of 11.25 and the average post-test value for the control class was 66.50 with a standard deviation of 13.78. Normality and homogeneity tests at the level of =0.05 stated normal and homogeneous and one-party hypothesis testing t-stat > t-table (2.99> 1.67). Thus, it can be concluded that the use of a virtual laboratory can improve student learning outcomes in the basic physics practical subject of Kirchoff law
