ABSTRACT
Recent research has revealed that basic computer input capabilities can substantially facilitate or impede people's ability to produce ideas and solve problems correctly. This research asks: What type of interface provides best support for inferential reasoning in both low- and high-performing students' Students' ability to make accurate inferences about science and everyday reasoning tasks was compared while they used: (1) non digital pen and paper, (2) a digital pen and paper interface, (3) pen tablet interface, and (4) graphical tablet interface. Correct inferences averaged 10.5% higher when using a digital pen interface, compared with the tablet interfaces. Further analyses revealed that overgeneralization and redundancy errors were more common when using the tablet interfaces and among low performers. Implications are discussed for designing more effective computational thinking tools.

The impact of interface affordances on human ideation, problem solving, and inferential reasoning
This article presents two studies investigating how computer interface affordances influence basic cognition, including ideational fluency, problem solving, and inferential reasoning. In one study comparing interfaces with different input capabilities, ...
Pen-top feedback for paper-based interfaces
UIST '06: Proceedings of the 19th annual ACM symposium on User interface software and technologyCurrent paper-based interfaces such as PapierCraft, provide very little feedback and this limits the scope of possible interactions. So far, there has been little systematic exploration of the structure, constraints, and contingencies of feedback-...
Experimental analysis of mode switching techniques in pen-based user interfaces
CHI '05: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsInking and gesturing are two central tasks in pen-based user interfaces. Switching between modes for entry of uninterpreted ink and entry of gestures is required by many pen-based user interfaces. Without an appropriate mode switching technique, pen-...
