2. Collaboration throughout Communication = Learning Access for all Engagement for each Effective learning Effective learning

3. But… communication barriers lead to missed learning opportunities

4. Young children spend 75% of their school day involved in listening activities Research Services, 2007

5. Mild Hearing Loss can hold students back 30% of children grades K-3 didn’t pass a 15dB hearing test 70% with MHL will suffer academic deficiency by 6 th grade Source: MARRS Project 1979-1993

8. Younger listeners can’t fill in the blanks Children need to receive 90-100% of information carried by the spoken word Handbook of Acoustic Accessibility, 2012

9. There are other challenges

10. Small group instruction is difficult How do I facilitate COLLABORATION? CHALLENGE Learning & behavior MANAGEMENT CHALLENGE What is going on? ASSESSMENT CHALLENGE

11. What’s the cost? Limited access isolates students Disengaged students get bored Collaboration turns into chaos

12. The unique flat-panel design delivers amazingly intelligible speech, distributed evenly across the room.

13. Flexible two-way communication system designed for differentiated instruction and other types of small group learning.

14. Small group instruction 2-way audio communication Up to six student groups Clarity to the whole group Team-teaching Exclusive technology* New MirandaNet Research Report

16. Components

17. Redcat Access: The “Brains” of the Operation Provides the whole group instruction component Considered the “base station” for all communication flow MUST have Redcat Access for all other devices to work

18. Redcat Access (Access version of Redcat) Key advantages: Increased transmission range Coverage in larger, open areas No interference with IR interactive projectors or other classroom tech No installation required

19. Flexmike Teacher Microphone Pendant style microphone – smaller and lighter than infrared Redmike Integrated earbud and lanyard for student group monitoring Team-teaching capability Microphone volume control standard Audio input to connect and direct wireless audio Utilizes Lightspeed AAA NiMH rechargeable battery pack

20. Flexcat student group pods Battery powered two-way audio pods Includes integrated speaker and microphone NiMH rechargeable battery pack (10+ hours) Up to 6 pods can be used with a system Speaker volume control on bottom Teacher controls microphone (monitoring) volume level with remote Call button allows students to request assistance Beep in teacher’s ear, pod # blinks on remote

21. Flexcat teacher remote Simple handheld teacher remote control Whole group instruction Amplified through Redcat Access = center button Pod selection (1-6) Microphone mute/unmute Silent monitoring (muted) Two-way conversations with groups (unmuted) Earpiece volume control (monitoring) Rechargeable battery Second teacher uses second remote

22. Charging Station Organizes and charges all components Charging slots for: 4 pods; 2 Flexmikes; 2 remotes Pods 5-6 charge via cable from the side of charging station Storage slots for earbuds Components require daily overnight charging Red light = charging Green light = charging complete
