Title: The Power of Feedback: Improving SketchTivity’s Feedback System
Perspective sketching is a skill that is required for a variety of jobs including, but not limited to, architectural design, graphic design, and engineering. Sketching however, is a difficult skill to grasp for people early and can take a while to learn. Recently, there have been many intelligent tutoring systems (ITSs) designed to help improve people’s drawing skills. The feedback system for the perspective drawing lessons in SketchTivity, one such ITS, is currently limited to smoothness, speed, and accuracy of the lines. Our team plans to improve upon this feedback system so that the feedback provided to a user is now more nuanced as well as more actionable to reaffirm future learning. To evaluate our system we will conduct a user study with 40 students that involves going through several sketching lessons and then sketching a street corner in 2-D perspective. We plan to run a between-subjects user study with our participants to determine if our adjustment has any effect on the improvement of sketching skills and the usability of the application. We hope to determine that providing the user with data for their smoothness, speed, and accuracy after four sketching prompts can cause an overall improvement in the students’ scores in comparison to at the end of their sketching session. The algorithm that we created to identify a student’s potential issue we hope will be able to provide accurate, actionable feedback in most situations. The visual alterations we made to SketchTivity we expect to have a positive impact on the perspective feedback system and alter the students sketching performance. In future iterations the algorithm should be further refined and the data collected from the students sketches should be further developed to provide more data to create more actionable recommendations for improved sketching performance and retention.  more » « less

  1. Freehand sketching equips engineers to rapidly represent ideas in the design process, but most engineering curriculums fall short of equipping students with adequate sketching skills. This paper is focused on methods to improve engineers’ sketching skill through type of instruction, length of instruction, and delivery of and feedback for assignments using Sketchtivity, an intelligent sketch-tutoring software. We answer several key questions for providing better sketching education for engineers. Does perspective training improve freehand drawing ability? Can an intelligent tutoring software improve education outcomes? And how much sketching instruction is necessary for engineers? Analyzing the changes in sketching skill from pre- to post-sketching instruction between different instruction types (n = 116), we found that perspective sketching instruction significantly improved freehand sketching ability compared to traditional engineering sketching methods. When comparing pre to post sketching skill of students using Sketchtivity (n = 135), there was no significant difference in improvement between students using the intelligent tutoring software and those that exclusively practiced on paper – both groups improved equally. However, completing sketching tasks on tablets did not hinder students’ skill development even when measured on paper. Future work will more directly explore the influence of Sketchtivity on sketching skill development. Additionally, we found that five weeks of sketching instruction greatly improves sketching skill compared to only three weeks of instruction (n = 108), but both approaches significantly improve sketching self-efficacy. These outcomes support more extensive sketching instruction in engineering classrooms, and changes in instruction type to promote more freehand sketching skills.

  3. This Research Work In Progress Paper examines empirical evidence on the impacts of feedback from an intelligent tutoring software on sketching skill development. Sketching is a vital skill for engineering design, but sketching is only taught limitedly in engineering education. Teaching sketching usually involves one-on-one feedback which limits its application in large classrooms. To meet the demands of feedback for sketching instruction, SketchTivity was developed as an intelligent tutoring software. SketchTivity provides immediate personalized feedback on sketching freehand practice. The current study examines the effectiveness of the feedback of SketchTivity by comparing students practicing with the feedback and without. Students were evaluated on their motivation for practicing sketching, the development of their skills, and their perceptions of the software. This work in progress paper examines preliminary analysis in all three of these areas.
