Actualization of user-centered information system with tasks and functionalities that duly addresses users’ needs had been a motivating force for researches in user-centered design (UCD) generally. In designing Information Visualization (InfoVis), UCD models and methodologies have been adapted to address the peculiarity and diverse domain specifics of InfoVis. This UCD models’ adaptation has been done in geovisualization, spatiotemporal InfoVis, biological data visualization, among others, with none on students’ data focused InfoVis, despite the domain users’ peculiarities. Furthermore, our study on actualization of higher education institutions (HEIs) students’ data-focused InfoVis observes the incompatibility of the existing InfoVis UCD models of past related studies with the actualization of HEI domain-specific InfoVis. This incompatibility is arguably traceable to the peculiarity of the domain InfoVis users –data administrators, data analysts, the policy administrators and decision makers. Due to our work field experience, and objective argument from literatures reviewed, we employed a comparative content analysis and in-depth critique methods to modify the existing InfoVis UCD methodologies so as to feature additional stages to comply with our domain specificity. This study therefore presents a modified InfoVis UCD methodology that attends to the observed limitations of the previous works, and finally, our work in progress is presented.

9. Observed Necessary Modifications…
a. Visualization Awareness and Domain Visualization are
opined to be prone to procedural redundancy.
b. Work Domain Analysis to be divided into two: Domain Study
and Tasks Elicitation and Validation.
c. Conceptual Development is re-named Conceptual
Framework Development.
d. Expert Review is introduced as a separate stage after the
Conceptual Framework Development.
e. An experimental study is introduced after the Debugging
stage

10. The Need for a Modified InfoVis UCD
Our preliminary study also shows that:
The multidimensionality of HEI students’ data
and the newness of InfoVis to HEI decision and
policy makers demand a modified UCD
methodology.
This will involve early and repetitive exposure of
the domain users to the InfoVis.
This study proposes a modified InfoVis UCD
methodology which is used in our on-going
research work in HEI students’ data-focused
InfoVis.
