Analyzing the Students’ Perception of UML Diagrams: Instruments Used in Evaluation

Unified Modeling Language (UML) has been adopted as a standard modeling language in the software industry for the graphical representation of analysis and design models. Due to its importance, UML is taught in most undergraduate majors in Software Engineering and Computing. However, little is known about the students’ perception regarding the UML diagrams. We conducted an exploratory study to investigate the students’ perception regarding UML diagrams acceptance. In this study, we investigated five UML diagrams taught for the undergraduate students from Federal University of Amazonas. These UML diagrams are: class diagrams, use case diagrams (and specifications), sequence diagrams, state machine diagrams, and activity diagrams. In order to evaluate the perceptions of senior undergraduate students on UML diagrams and thus help instructors improving the teaching of its importance, we applied Technology Acceptance Model (TAM) questionnaires. This technical report presents the TAM questionnaires for each UML diagram. Thus, other researchers may replicate it, providing outcomes in different contexts.
