The study results indicated that, in general, using interactive whiteboards was associated with a 16 percentile point gain in student achievement. This means that we can expect a student at the 50th percentile in a classroom without the technology to increase to the 66th percentile in a classroom using whiteboards.
In addition, three features inherent in interactive whiteboards have a statistically significant relationship with student achievement. The first is the learner-response device—handheld voting devices that students use to enter their responses to questions. The percentage of students providing the correct answer is then immediately displayed on the board in a bar graph or pie chart. Using voting devices was associated with a 26 percentile point gain in student achievement.
A second feature is the use of graphics and other visuals to represent information. These include downloaded pictures and video clips from the Internet, sites such as Google Earth, and graphs and charts. Use of these aids was also associated with a 26 percentile point gain in student achievement.
A third feature is the interactive whiteboard
reinforcer—applications that teachers can use to signal that an answer is correct or to present information in an unusual context. These applications include dragging and dropping correct answers into specific locations, acknowledging correct answers with virtual applause, and uncovering information hidden under objects. These practices were associated with a 31 percentile point gain in student achievement.
