Dave and Paula Schoeff are a teacher and engineer writing team. Together we bring 20 years of teaching and manufacturing expertise to our lessons. We have been writing project-based STEM lessons for about ten years and our work is used in school districts in the United States and China. Several of our lessons are also included in NSTA’s STEM Road Map curriculum series. In August 2019, we began teaching STEM Clubs in our home to explore STEM experiences as a relationship-building tool. The clubs are composed of teams who work on a couple major projects per semester. This structure is unique in that each team is an intermediate student (grades 2-6) and a parent, grandparent, or other mentor. We use member input and our observations from the STEM clubs to fine-tune lessons and activities offered on our Teachers Pay Teachers store.
