Classroom Amplification Systems

Classroom amplification systems are audio system devices used to raise teacher's voices 10 - 15 dB above the general noise level in the classroom.  The systems are wireless and infrared with a microphone worn on a lanyard around the teacher's neck.  "Classroom amplification systems have been used around the country for over 30 years, and have a large body of research demonstrating their efficiency," states Leah Chelius, Speech Language Pathologist at Trost Elementary School. 

In 2003 an action research project was conducted to look at the effectiveness of the systems that had been placed into Trost Elementary classrooms.  Some of these results were astounding:

• 43% reduction in student off-task behaviors;

• 72% reduction of teacher redirections and student behaviors;

• Increased growth over students in un-amplified classrooms demonstrated on the DIBELS, DRA and TESA tests in grades 1, 3 and 4; and

• Overwhelming positive response from teachers regarding classroom atmosphere, voice fatigue, student use of microphones to enhance reading fluency, etc.
