A teacher can be the most important resource in a school. When the teacher's attitude derives from asset-based thinking, positive impact can occur for both teacher and student. Asset-based thinking is defined as "a way of viewing reality." Those who embrace this model approach things from a positive as opposed to a negative perspective. Asset-based thinkers look for what is working and what strengths or assets exist within themselves, their relationships, and the situations in which they find themselves, and then build on those strengths to accomplish their goals. Asset-based thinking taps inner strengths to realize "personal power that comes from leveraging the assets that make you "you"." In other words, assets that exist within can be used to create change. Leadership involves influence. When used ethically and positively, this influence opens up doors for creativity, collaboration, and development of other teacher leaders. Those who use asset-based thinking dig deep inside to identify and commit to areas they feel most compelled to impact. With ever-diminishing resources, schools must look within to supply resources for supporting continuous professional learning. Educators must consider each other the most valuable resource in a system, to be developed and supported with leadership, structures, tools, and processes for promoting continual professional learning. This article discusses how Doug Franklin (not his real name), a teacher who led a professional learning community, was considered as a teacher leader using asset-based thinking, a prime example of a resource that is too often left untapped.
