The function of text description in sketch promotion

Sketching education is a hot topic in design and this paper presents an exploration on the elements of sketch to develop its quality. It focused on the relationship between text description in sketch and sketch quality. By monitoring the sketch process and recording the sketch data, the relationship was chiefly explored by coding the creative points in sketch process and comparing the behavioral properties of creative points in sketches. Sketches are also divided into text sketches and graphic sketches according to their description form. The analysis showed that behavioral patterns related to text description were the same between high quality group and low quality group, but high quality sketches had more text description around the creative points. It also presented that high quality sketches with text description sketched slower in creative points. We advise that emphasis on combination of textual and graphic thinking maybe more proper in designers´ sketching education.
