Much research examines professional learning for pre-service and beginning teachers. However, in midcareer, teaching satisfaction and effectiveness are challenged by decreased recognition and support and increasing stressors including isolation, accountability demands, mentorship roles, and personal/family responsibilities. Often, midcareer teachers (MTs) pursue graduate degrees to advance skills, licenses held, and achieve recognition. This qualitative exploratory study examined classroom community (CC) development across three graduate seminars for MTs. Increased CC was connected to course structures and instructor actions which supported teachers' reflection upon practice and envisioning of possible selves. Personal/family selves, teaching selves, and academic selves emerged. The model developed connects CC, motivators, and enacted classroom practices to each set of possible selves. Findings suggest increased attention to campus-based graduate seminars as avenues for the development of trust, open dialog, reflection, strategy building, and improved classroom practice among MTs.
