Perceived Usability Evaluation of Educational Technology Using the Post-Study System Usability Questionnaire (PSSUQ): A Systematic Review

Abstract

Given that educational technology has increased tremendously, usability testing is a necessity to maximize the efficiency of technological tools in education. The findings of a systematic review including 42 research papers that evaluated the educational technologies’ perceived usability with the Post-Study System Usability Questionnaire (PSSUQ) and the Computer System Usability Questionnaire (CSUQ) are presented in this article. The results were categorized according to the following factors: (a) score derived from evaluating usability with PSSUQ/CSUQ, (b) type of educational technology employed, (c) subject studied, (d) educational stage, (e) participant type, (f) age, and (g) participant count in each survey. The usability levels were found to be satisfactory (M = 72.75, SD = 15.12) from the statistical analysis of all surveys (N = 58). The mobile applications category showed a very good mean PSSUQ/CSUQ score (M = 81.53, SD = 12.61) followed by the multimedia category with 73.89 (SD = 19.69) and internet platforms (M = 73.23, SD = 7.74). The educational stage (p = 0.01) and the participant type (p = 0.005) seem to relate to the obtained PSSUQ/CSUQ scores. However, the participants’ age, the subject being studied, or the participant count in each study did not exhibit any significant correlation with the PSSUQ/CSUQ scores. Over the course of time, a marginal non-statistically significant improvement was noted in terms of perceived usability (p = 0.136).
