Usability Testing for Teachers' Lesson Planning Services

The purpose of this paper is to present and discuss the results from the usability and attractiveness analysis of an information system for sharing lesson plans with open educational resources (OER). For this, Human-Centered Design practices were adopted to better understand the needs related to the act of planning lessons and the meaning given to this planning. As a complement, studies have been carried out on the professional activities involved in the execution of lesson planning. With this set of information, programmers and designers have used the Brainsketching collaborative creativity technique to materialize the team's ideas into low-fidelity prototypes. Then, the prototype was scanned and received interaction features. A task analysis was performed for each of the main tasks in order to understand how actions with representative users would take place. After this step, a usability test was applied to a group of 18 high school teachers from public schools in the city of Recife, Brazil, in the first semester of 2017. The results point to problems of satisfaction and use of the application's high-fidelity version which has been tested. These issues were related to users' critical tasks and aspirations. Although it presents usability and satisfaction problems, the application is recognized by the target group as important and with potential for evolving.
