The National Council for Accreditation of Teacher Education has called for strengthening teacher preparation by incorporating more fieldwork. Supervision with effective instructional feedback is an essential component of meaningful fieldwork, and immediate feedback has proven more efficacious than delayed feedback. Rock and her colleagues have developed the wireless Bug-in-Ear (BIE) system to provide immediate, online feedback from a remote location (electronic coaching or e-coaching), and they have pioneered the use of BIE e-coaching (BIE[superscript 2] coaching) in coaching teachers in graduate education. Other research has also documented successful use of the BIE system with teachers. This case study explored the use of the BIE tool for undergraduate student teacher supervision in the hands of a novice BIE[superscript 2] coach, including the ease with which BIE equipment can be set up and operated by a novice coach and naive users in the classroom. The findings provide support for the use of BIE[superscript 2] coaching as tool for undergraduate student teacher supervision, based on the changed behaviors during reading instruction exhibited by two out of three student teacher participants. Consistently increased use of targeted instructional behaviors was seen after just five coached lessons, and also seen in follow-up observations during which no coaching was provided. Student teachers reported that benefits far outweighed drawbacks in BIE[superscript 2] coaching, but they found it challenging to simultaneously monitor elementary pupils and BIE feedback. The experience of the researcher showed that BIE[superscript 2] coaching could be accomplished by a novice electronic-coach with significant previous coaching experience, but that additional training on the use of concise feedback language and affirming vs. corrective prompting may be needed for less experienced coaches. While this case study documents the experience of only one coach, and only three student teachers all working in homogenous, suburban classroom sites, BIE[superscript 2] coaching showed great promise as a student teacher supervision tool. Future research on training for e-coaches, determining which undergraduates will respond to BIE[superscript 2] coaching, and discerning patterns of responsiveness to coaching are called for.
