The course ir really good (I am in week two). The problem is the locked asignemnts (i have to wait until June 28 to complete this week). I find it really frustrating trying to use my extra free time to move on the course and get blocked by locked assignements. I had other courses where you could move at the speed that was more comfortable for you. (I also don´t like the fact that the course has specific start dates). This makes the course unengaging and hard to follow.

He hecho cursos en Edx de MIT y Harvard y eran divertidos, prácticos y muy bien explicados, siento que aprendí. Este curso, los profesores explican todo de manera abstracta, la calidad del video es mala, no hay ejemplos concretos. No hay tareas cortas para fijar conocimiento luego de cada 5 videos. Es muy aburrido como hablan, les falta dinamismo. No volvería a hacer un curso en coursera

If you are going to present a course you should probably give the student the information that you will test them on. If prerequisites are required list them. There was not a single mention of what the symbols in their formulas represented or how to interpret them. At age 52 I failed my first test. Thanks!

Another approach but mathematical demonstration is probably possible.

Coursera offer technologies to avoid classroom demos on whiteboard.
