Education has always existed since the inception of the human race. However, it was informal in the beginning but took a more formal and structured shape later. The objective remained the same: to prepare the inquisitive learners of today for the challenges of tomorrow. Now, we are in the 21st century, where dynamic curriculum, engaging pedagogy, and performance-based assessments are the essential elements for an impactful education system, where integration of technology is indispensable and inseparable due to the extensive exposure of learners to media and information. These circumstances make the establishment of engaging and relevant education a true challenge for educators.
It is an open fact that the challenges of the 4th industrial revolution cannot be encountered through conventional educational approaches. Our STEM education model, based on STEM Resource books and makerspace, is developed according to the Science, Technology, Engineering, Mathematics (STEM) approach, inter-disciplinary and integrated learning that engages learners in learning, inculcates skills development and enhances problem-solving abilities.
STEM challenges in this book are developed by STEM-certified educators, based on Next Generation Science Standards, The National Curriculum of England and the Common Core for Mathematics. These challenges were then reviewed by international STEM experts & organizations, including STEM.org, an eminent research & accrediting body in the United States. These challenges and pedagogy were put to the test in a long & robust process of prototyping on students & their teachers for their feedback on learning attainment and experience.
Expert teachers appreciate and endorse the systematic initiative of STEM programs in schools, through which learners are challenged to solve problems of real-world situations and emerge as innovators and inventors. Apart from developing collaboration and communication skills, students choose their career paths and achieve their goals in life.
