“…While completely free-form work such as writing with a stylus on a tablet might be ideal, challenges remain to implementing such technologies, although progress continues to be made along this front (Fu & Kara, 2011;Kara & Stahovich, 2004;LaViola, 2007;Lee, de Silva, Peterson, Calfee, & Stahovich, 2008;Peschel & Hammond, 2008). Within the constraints of conventional keyboard and mouse interactions, one can still grant the user opportunities to commit errors similar to those observed when students solve with pencil and paper.…”

Problems faced by engineering students involve multiple pathways to solution. Students rarely receive effective formative feedback on handwritten homework. This paper examines the potential for computer-based formative assessment of student solutions to multipath engineering problems. In particular, an intelligent tutor approach is adopted and tested out on problems of truss analysis, studied in engineering statics. With a cognitive model for solving the class of problems, the tutor allows the student wide latitude in solution steps, while maintaining sufficient constraints for judging the solution and offering feedback. Proper selection of judging points prevents interference with productive student work, while avoiding accumulated errors. To monitor student learning, efforts to apply distinct skills were extracted on the fly from student work. Using statistical methods developed for intelligent tutoring systems, metrics of the effectiveness of the feedback and areas for further improvements were gleaned from error rates in successive opportunities to apply distinct skills.

“…Although progress continues to be made in computerized interpretation of completely freeform work, for example via writing with a stylus on a tablet [9][10][11][12][13], such technologies may be limited for the foreseeable future; we have therefore defined unconstrained as still within the confines of a mouse and keyboard user interface.

“…This aspect is important for education, because it allows the researcher to study and extend the existing practice, in order to integrate the classroom more easily. Practices existing in the classroom that can be augmented include taking notes [17], reading textbooks [18], storytelling [19,20], or drawing schema [21].…”

Abstract. Paper interfaces offer tremendous possibilities for geometry education in primary schools. Existing computer interfaces designed to learn geometry do not consider the integration of conventional school tools, which form the part of the curriculum. Moreover, most of computer tools are designed specifically for individual learning, some propose group activities, but most disregard classroom-level learning, thus impeding their adoption. We present an augmented reality based tabletop system with interface elements made of paper that addresses these issues. It integrates conventional geometry tools seamlessly into the activity and it enables group and classroom-level learning. In order to evaluate our system, we conducted an exploratory user study based on three learning activities: classifying quadrilaterals, discovering the protractor and describing angles. We observed how paper interfaces can be easily adopted into the traditional classroom practices.
