In conclusion, both experts and students strongly agree with the indicators of the instrument in terms of content quality, technical quality, and instructional quality. These statistical results from experts and students are further supported by the verbatim of both groups that show interest and support for the developed module.

The results of the data analysis indicated that the experts and students strongly agree on the acceptability and usability of the web-based interactive spatial intelligence module. The parameters for evaluation were content quality, technical quality, and instructional quality. Ten lecturers and 39 freshmen architects assessed the module using the instrument adopted from Mercado. The module consists of activities involving mental rotation and spatial visualization using the web version of SketchUp over a span of 9 weeks. This study aimed to assess the developed web-based interactive spatial intelligence module intended for freshmen architecture students. For this reason, a web-based interactive spatial intelligence module is essential to enhance the spatial understanding of freshmen architecture students. However, spatial intelligence is malleable and could be improved through interventions.

Low spatial intelligence is also a barrier to success in STEM disciplines. Spatial intelligence is important in design-based disciplines like architecture, but it is not given much attention despite its influence on students' performance.
