Abstract
Veteran biology teachers are at risk of leaving the classroom due to burnout, feeling uninspired, and overall job dissatisfaction. One way to keep veteran teachers engaged is through continued mentoring. Yet current mentoring programs vary in scope, often focus too heavily on one-to-one talk, with mentors serving as therapists, and generally fail to include veteran teachers. Considering this is not how schools operate, we argue active mentoring for veteran teachers is best when embedded into regular school practice. Collaborative mentoring, as we have termed it, pairs experienced high school teachers with other veteran colleagues, including university professors, in professional development activities centering on improving classroom practices. We believe that collaborative mentoring holds potential to meet the needs of all stakeholders-high school students for support in learning laboratory and writing skills; university faculty for hands-on classroom work and reflective practice, as well as for sharing content and pedagogical knowledge with professionals in the field; and, specifically, veteran biology teachers for expanding access to meaningful professional development opportunities. Focusing on applicable classroom pedagogy serves as a cost-effective model for professional development for veteran teachers, possibly increasing job satisfaction and teacher retention in high schools across the nation.
