We used to think that everyone could teach. That if someone is a good professional and expert in her field, she will be a good instructor, teacher, or mentor. And that she will easily transfer her knowledge to others. This view is far from reality and harms. Every time there are new (and not that new) teachers and educators who get into this trap. Teaching is a profession that should be mastered like any other one. At this talk, we will try to answer the following questions. What are the main challenges while teaching adults? How to take into account our cognitive abilities and brain’s behavior while designing a learning experience for your students? How and when does it better to use the ed-tech tools to leverage the study process? This talk was delivered at Engageducate conference from Softserve University
