Abstract

The "Specialized Educational Unit Deaf of Chimborazo" lacks technological tools that allow accessibility to teaching material inside and outside the educational institution for learning sign language for early education students, so in the present integration work, the curricular objective was to develop and evaluate a web application focused on the continuous improvement of the teaching and education of people with hearing disabilities and their access to technology from their homes. Analytical, deductive, and statistical methods were used, such as data collection techniques, documentation review, field observation, and surveys carried out with teachers to determine multimedia elements that replicate the teaching material presented in the classroom; developing the application through the use of the PHP programming language, based on the Laravel framework with a model-view-controller architecture, in conjunction with the MySQL database manager, Wordwall for the design of interactive games to reinforce the learning process, templates extracted from the themewagon page, selecting didactic and interactive structures, such as the Visual Studio Code editor and the express PHP hosting server for access to the web. The SCRUM methodology was used to carry out work divided into iterations for better control of time, development, and implementation of the software product. In addition, the ISO 25010 standard was applied to measure the level of usability, the results obtained through the tabulation of survey data adapted from the SUMI (Software Usability Measurement Inventory), CSUQ (Computer Systems Usability Questionnaire), and SUS (System Usability Scale), carrying out the data study based on a documented and approved usability scale for software evaluation, obtaining 80.48% usability, considered satisfactory with an acceptable score.
