The article presents the processes and the results of the application of some ergonomic techniques, used to evaluate the usability of the virtual learning environment adopted by the Distance Education Center of the Federal Institute of Espírito Santo -Brazil.

Perceived usability evaluation of Microsoft Teams as an online learning platform during COVID-19 using system usability scale and technology acceptance model in India

“…However, no details are provided as to how good SUS is a replacement for the PEOU component of TAM, and whether they measure the same thing. Authors in ( Pereira and Anamaria, 2012 ) have used three different techniques for evaluating a Moodle based learning platform (including SUS) and reported that SUS is an effective tool for measuring the usability. However, they did not report any SUS usability score.…”

“…While the average SUS scores for the students are 62.01, those from the teachers are 74.45, indicating that the perceived usability is better for the teachers. Authors in ( Simoes and Moraes, 2012 ) designed a Moodle based distance learning platform and tested it using two different methodologies: SUS and heuristic evaluation. Both the methods unveiled that their designed system had serious usability problems.…”

Evaluation of skills acquisition using a new low-cost tool for CPR self-training

“…The usability of the CPR Personal Trainer scored 78, which, based on the literature, 23,29 is considered above average.…”

“…A preliminary assessment of the CPR Personal Trainer's usability was performed with the students from the intervention group (n = 21). For that, an European Portuguese translation 23,24 of the System Usability Scale (SUS) questionnaire 25 was applied.…”

“…The SUS score 23–25 is calculated by summing up all individual items. For items 1, 3, 5, 7, and 9 (positive statements) the score contribution is the scale position minus 1.…”
