An interesting article from the September, 2005 issue of the THE Journal entitled "Interactive Learning Environment Keeps Modesto Students Engaged" is available
here.The article describes how Modesto City Schools in California invested a portion of a $500,000 Enhancing Education Through Technology grant into Pearson's Classroom Performance System (CPS) wireless handheld response devices. 23 seventh-grade math and science instructors were recruited to use the technology, and cite anecdotal evidence as well as a 4-6% increase in students' test scores as evidence of the effectiveness of the technology.
The CPS system in which Modesto City Schools invested relies on infrared signals for transmission of student responses. Infrared poses some potential problems with interference and line of sight issues. Nevertheless, infrared systems cost considerly less than their more reliable radio frequency counterparts.
CPS software has a "Challenge" game format built in which allows students to compete in a friendly "Jeopardy-like" environment. It also has partnerships with textbooks in which instructors can download pre-constructed questions that match the content of textbook as well as state and national standards.
CPS handheld remotes do not display on the students' screen if the answer that they selected was correct or incorrect. Students must wait to hear from their instructor or view an overhead display to determine if they answered correctly. Other handheld devices (

It is unclear if the 4-6% increase in test scores is truly a result of higher levels of student comprehension and engagement, or if students simply gain more practice taking tests by using the handheld devices. It would be interesting to compare the number of "practice quizzes" given in previous years with the number of time the handheld devices were used this year in order to ensure that student improvement was not simply due to students becoming better test takers by being exposed to test-like environments more often.
