An investigation into keystroke latency metrics as an indicator of programming performance

摘要: Typing has long been studied in psychology and HCI, strong cognitive models for transcription typing exist. The goal of the present research was to test if there is any correlation between students' keystroking speed performance while they are programming. We results from two studies with computer science students conducted different contexts. Keystroke timings were recorded worked on Java Ada source code. Quality their programming work measured mainly terms completeness. In controlled experiment that lasted six hours, 39 undertook three change tasks a 6000 LOC application. field study, data collected over 6 weeks 141 unsupervised first year laboratories. both cases highly significant (P=0.001), moderately strong, negative correlations coding performance. With additional development, these techniques may have promise user modelling assessment as well educational diagnostics.
