In the environmental design professions, many students and practitioners lack confidence in visual communication skills, especially in the case of quick perspective sketching. For many, sketching as a beneficial design tool is not fully learned or appreciated.This study explores sketching fundamentals and a teaching technique to promote perspective sketching as an effective design tool. Experimental workshops were conducted with various beginning environmental design students in three universities. Students responded to a post-workshop questionnaire which attempted to solicit feedback about the demonstrated sketching technique as to whether the technique 1) increased their ability, 2) increased their confidence, 3) increased their enjoyment, and 4) increased their willingness to pursue sketching in the future. Students were also evaluated on the degree of improvement according to simplicity, clarity and proper perspective setting of their sketches.The results suggested that the workshop, teaching methods and sketching techniques were successful. Students showed marked improvement and indicated in the questionnaire that they enjoyed the experience and were pleased with their new skills. They also indicated a positive feeling about the teaching methods and the sketching techniques. / Department of Landscape Architecture
