Measuring Google Classroom's Usability Level from an Expert Perspective

The demand for the use of distance learning media, especially at the beginning of the covid-19 pandemic, led to the high use of one of the long-known distance learning media, namely Google Classroom. This study aims to provide empirical evidence of the effect of perceived usability on the use of Google Classroom recently. We use heuristic evaluation method to evaluate user interface of e-Learning with four expert participants who are also instructor/teacher in some courses, the data is presented in form of quantitative and in-depth in the form of qualitative. Result of the study showed that the highest severity level was 1 (cosmetic usability problem) in the first heuristic (visibility of system status): 2 from 4 expert said that Google Classroom does not provide visuals that help the user understand in which screen they are standing; and sixth heuristic (recognition rather than recall): 2 from 4 expert said that Google Classroom does not indicate which controls are currently inactive in clear visual way. This study introduces a new approach, risk opportunity measurement which is based on risk-based thinking of ISO 9001:2015 (standard of quality management system), to provide recommendations for improvement of problems found by evaluators to stakeholders based on principles/heuristics that have the highest to lowest risk opportunities for improvement and further development.
