EFFECTS OF SCREEN SIZE, SCREEN RESOLUTION, AND DISPLAY RATE ON COMPUTER‐BASED TEST PERFORMANCE

摘要: Computer-based tests administered in established commercial testing centers typically have used monitors of uniform size running at a set resolution. Web-based delivery promises to expand access, but the price less standardization equipment. This study evaluated effects variations screen size, resolution, and presentation delay on verbal mathematics scores sample 357 collegebound high school juniors. There were 3 display conditions crossed with 2 rate conditions: 17-in. monitor resolution 1024 × 768, 640 480, simulated 15-in. 480 items presented either no or 5-sec between questions (to emulate slow Internet connection). No significant math found. Verbal higher, by about quarter standard deviation, larger high-resolution display.
