The primary goal of HIIT is to equip HE STEM teachers with the self-efficacy, competencies, and skills needed to understand the Instructional Technology principles and structures, leverage them rapidly to reduce the impact of closure and preserve the inclusive nature of learning opportunities. The HIIT framework enables HE STEM teachers to understand how to use learning technologies and digital tools in subject-specific teaching and learning in a systematic way. It will improve readiness for digital education, help them apply the principles of instructional technology horizontally throughout their teaching, and choose the right technology or tool for the proper context to achieve their learning goals.
