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.
