Using three-tier diagnostic test to asses students' misconception of simple harmonic oscillation

This examination includes the advancement of a three-level analytic test to gauge understudies' comprehension of simple harmonic oscillation. The Simple Harmonic Oscillation Test (SHOT) is a 10-items three-level demonstrative test comprising of three-level things for surveying understudies' understanding of simple harmonic oscillation concepts. The SHOT was controlled to 50 understudies in the control class and 50 understudies in the experimental class. Cronbach alpha unwavering quality lists for the SHOT were assessed to be .73 and .85 for the control and experimental class, individually. Point-biserial coefficients went from .22 to .67, a normal of .42 for the control class and with a normal of .44 for experimental class. The results research showed that a three-tier diagnostic test able to reduce the misconception of simple harmonic oscillation. There is requirement for more investigations to create three-level tests in other branches of knowledge.
