Designing of virtual laboratory on elasticity for Physics learning

Abstract

Elasticity is one of the materials that students learn through laboratory experiments. In general, real and virtual laboratory conditions are still limited to spring elasticity experiments where the elasticity properties can be observed directly to determine the material's elastic modulus. While on other objects and materials, elasticity experiments are still problematic to do because of the limitations of measuring instruments and microscopic observation scales. This study aims to produce a virtual laboratory of the Elasticity of various materials using wire for physics learning in universities. This study chose the Development Research (DDR) design with the ADDIE model for its development. The feasibility of the virtual laboratory is seen based on the results of the expert validation test. This research produced a Virtual Laboratory on Elasticity using aluminum, steel, iron, brass, nickel, copper, and tin wire. This virtual laboratory has four variables that can be varied, namely the type of wire material, the mass of the object, the diameter of the wire, and the initial length of the wire. The validation results with expert input show that the Elasticity virtual laboratory is valid and can be used for learning physics in universities.
