TeacherGPT, a multi-purpose teaching tool developed in Aotearoa, aims to support primary school teachers with planning and resource creation. The tool is designed to reduce administrative tasks and preparation time, enabling teachers to create editable classroom materials quickly. Key features include the generation of Google Slides presentations, visual resources like worksheets and posters, lesson and unit plans, and on-demand online learning games and activities tailored to student needs. A significant aspect of TeacherGPT is its emphasis on editability, allowing teachers to modify content and ensure it aligns with their students' specific requirements. The platform also offers a school plan with features like school-wide instructions, enabling consistent and context-aware AI implementation across an institution. These instructions can ensure that planning links to school values, resources include te reo Māori translation, and outputs meet school-specific expectations. TeacherGPT has been developed in collaboration with primary schools in Hamilton, including St Joseph’s Catholic School, to understand teachers' needs and concerns regarding AI. This collaboration has shaped the tool's features, focusing on practicality and ease of use. The developers, Eden and Kelly, who have extensive experience in enterprise software and education, emphasize that TeacherGPT aims to provide teachers with a strong starting point, allowing them to add the final touches based on their professional judgment. The tool is intended to alleviate pressure on teachers by streamlining resource creation, enabling them to dedicate more time to teaching.
