She received her BA from Eckerd College and her MA in Sociology from the University of South Florida. With over seven years of teaching experience in Hillsborough County Schools, Jen has been through numerous annual evaluations. This year’s annual review was scheduled during her “most difficult” class, but she wasn’t worried because her lesson plan had a secret weapon… Gizmos! Her whole group Gizmo lesson scored “Exemplary” in all domains of evaluation, which included demonstrating knowledge of content and pedagogy, designing coherent instruction, organizing physical space, showing professionalism and using assessment in instruction. Jen used the Percent of Change Gizmo during her lesson, which allows students to apply markups and discounts using interactive percent rulers. “The full lesson spanned over a 3-day period. The Gizmo reinforced concepts such as percent of change, sales tax, tip, discount and markup as one great big global concept.” As a result, students were able to improve number sense for percents with this dynamic, visual tool. The lesson description below was taken from her peer-evaluation: “She effectively planned and utilized the Gizmo to further student learning as well as demonstrated a wide range of effective pedagogical approaches during the lesson. Students were strategically paired and then adjusted as needed for the lesson. Students were provided opportunities to peer and self-assess when comparing responses, checking with the calculator and viewing the Gizmo.” If you are considering using Gizmos with your students, Jen has one thing to say, “If people don’t believe this stuff works, they clearly haven’t used it enough or even tried it!” Try Gizmos today to see how you can take your students’ learning to the next level!
