This paper seeks to understand the interplay between the acts of pen-and-paper-based sketching and the use of mental imagery. A protocol study of four novice designers was conducted in two different environments: with access to sketches only; and blindfolded and delayed sketches. In total there were eight 45 minute design sessions. This study confirms that sketches and mental imagery support ideation stages in unique ways and both are equally germane. Identified interplaying roles when only sketches are utilized are: supporting, co-evolving, and reflecting roles. In addition, interplay can happen at the exact moment or distantly; and the order of an interplay depends on the designers’ strategy. In sessions where sketches are for externalizing design proposals only at the end, identified roles are: generative and provocative to idea exploration. It is also observed that gesture does not compensate for the absence of external representation, although it conveys important design messages.

In the past few years, higher education across the world transitioned to different online platforms where virtual classrooms were set, following national guidelines during the COVID-19 pandemic. This paper analyses qualitative data from first-year students in architecture from a higher education institution in the UK and draws on lecturers’ reflective observations of teaching during the COVID-19 pandemic. The findings of this research provide some critical considerations for the long-term impact of the virtual design studio on architectural design pedagogy and teaching methods in first-year studies. This research found that technology integration enabled innovative design methods, improved digital literacy, and enhanced collaboration in first-year architectural education. While online learning met learning objectives, it posed challenges like social isolation and motivation issues. The study underscores the importance of investigating virtual design studios and technology integration in early architectural education, offering opportunities for curriculum development and future research. These findings have broad relevance for educators teaching first-year architecture students globally.

Previous empirical studies in sketches and mental imagery showed that there is no significant difference in overall quality and possibility to use mental imagery as design tool. This preliminary study explores distinctions between two kinds of sessions in terms of how ideas are generated. Four design sessions of two novice designers are used to unveil differences. Based on preliminary results, physical properties of sketches underlie differences, also the availability of visual cues apart from the drawings itself. During interpretation stage, sketches provides an additional dialogue which is not available in mental imagery session. The use of mental imagery as design tool in novice designers vary and may not as effective as in experts. Pauses and gesture in both sessions are found to be fundamental designing aspects, including in environment when sketches are allowed. When crucial differences are no longer assumed, interplaying roles between the two can then be explored further.
