February 27, 2023 - March 1, 2023


Louisville, KY


The POSB Math and Science Institute for Instruction has been held during odd years since 2011. In 2011, the Principals of the Schools for the Blind started the Institutes for Instruction with the following goals in mind:

  1. To build community and a support system among teachers of the visually impaired. Often, teachers feel isolated and don’t have easy access to other teachers for guidance and support.
  2. To provide professional development opportunities. The “POSB Institutes for Instruction” would include a training component, focusing on a particular area of instruction to inspire teachers and provide them with tools to improve their instructional practices.
  3. To establish online communities for individual disciplines in order to provide ease in communication and to share documents and other materials related to instruction.

There is no funding source associated with the Institute. It is completely supported by local schools for the blind and donations.

Keynote: A Walk Through Stem Education Materials from the American Printing House for the Blind — Mike Hudson

Monday, February 27, 8:15 AM–9:15 AM

APH published its first books in the 1860s. All were collections of wisdom—fables–which is curious in today’s educational environment. Our national obsession with STEM, and the sense that American children, and by projection, America itself, are slipping behind those from other nations, is cyclical. Mike Hudson, director of the Museum of the American Printing House for the Blind, will take us on a journey through the rise and fall and rise and fall of STEM education materials for kids who are blind or have low vision.
