Description

A ten-item, five-point Likert self-report instrument adapted from Brooke's System Usability Scale to measure users' perceived usability of an interactive learning environment.

Components

• Adapted System Usability Scale (SUS) administered after learning to assess the learning environment: The variable table lists an "Adapted System Usability Scale, SUS" based on Brooke (1996), consisting of "10 items, rated on a 5-point Likert scale" collected post learning. It was used to capture participants' usability ratings of the interactive learning environment, complementing the 9-point Likert ratings of mental effort, concentration, interest, comprehension and difficulties related to the learning material.
