Doubtnut leverages technology to make education accessible for all.We have created an App using which students can ask study questions in Math by clicking the picture of the problem or concept. Subject matter experts then create a Khan Academy style video to answer each doubt. Why video, because in our experience as teacher/educator we have seen students not being able to understand text solutions. In fact around 30% of the questions asked on doubtnut so far are actually solved examples from textbooks. The reason for this could be twofold: i. Text solutions are usually the most optimal solution, which might not be the most intuitive one ii. Also, the solutions are optimized for printing hence not all logic and thoughts behind the problem solving are written. With video solution we try not only to find the answer but also make students aware of the problem solving approach employed by the expert. This will lead to deeper understanding of the concept. As of today the low teacher to student ratio and unavailability of good teachers are the biggest hurdles to effective doubt resolution. Doubtnut solves for it by reusing content that has already been created to resolve the doubts, because more students find the same question tough. Hence, a huge number of doubts can be resolved with limited number of teachers. Also the time required to create a video of ‘n' minutes is ‘n+2' minutes, which means the marginal cost is minimal, and will reduce to zero over time as we will have videos for most types of questions. Currently, we are working on developing technology to automate answering of questions asked previously using image recognition and Natural Language Processing.
