Let's get to the benefits about teaching partners. Before going on, teachers should not be slung together and be expected to act as a cohesive team. Administrators should be aware of their teachers strengths and weaknesses and pair accordingly. Doing this purposefully saves a great deal of headache in the long run and helps to bind people together because they get along.
Joan Moser, my first teaching partner, showed me how to partner. The first thing she did was to invite me into her world to learn about me. Taking this time no more than an hour or so set the stage for a great working relationship. One benefit of having a teaching partner is getting to know someone well and share friendship.
When partners are appropriately matched, synergy happens. Educational synergy is the energy that flows between partners. What does it look like? It looks like passionate discussions about learning, assessment, planning, learning outcomes, and other aspects of education. They play off one another to improve themselves as teachers by challenging false assumptions, teaching practices, and approach to learning. This kind of synergy benefits both teachers focused on learning.
Teaching partners have a place to turn when it gets bad. Sometimes parents create a nightmare with complaints, emails, or phone calls. Sometimes administration makes life in the classroom difficult to deal with. Sometimes students make classroom life crazy, and sometimes colleagues make it unbearable. Having someone your close with gives you a place to turn for help and pick me ups and for the times when you just need to complain.
Partners push each other to be better teachers by challenging each other's ideas, assumptions, pedagogy, communication, assessment, and other aspects. I don't mean challenging to be a bad thing but something helps both educators get better. There will likely be arguments but if the partners are really about helping every child learn then open conversations about practice shouldn't be a big deal.
Planning, designing common formative assessments and summative assessments, writing objectives, and pedagogy gets easier. Being in the teacher silo makes all of this much more difficult. Ideas can be bounced around and all aspects of teaching and learning gets better.
