How to Recover Deleted Coursera and Berkeley Courses from

In June 2016, deleted 472 open online courses as it migrated from an old system to a new system; from March to August 2017, UC Berkeley made all 350+ courses on Webcast.berkeley private. Fortunately, most of these courses have been archived by the Archive Team. This post provides the instructions for downloading and opening the archived courses.

The Deterioration of Coursera

Coursera is the biggest massive open online course (MOOC) platform founded in 2012 with over 1900 courses currently being offered. The website today is nothing like what it used to be in 2015, especially after moving to a new system in mid-2016. It’s not surprising that Coursera remains the alpha in the MOOC industry since it’s an oligopolistic market with universities mostly sticking to the same platform over time. But it’s mind-blowing to know that highly competent people can create a great platform and then destroy it a few years later.

So what happened? For each good feature they added, they removed five other great features. After the 2016 update, course providers are no longer allowed to place a promotional video in the course description and old videos are removed. Users could no longer click on professor names to see their profiles, which took Coursera a year to fix this problem. Professors should deeply appreciate the reappearance of their profiles, because not only are links to university profiles gone, the catalog of all university providers has also been deleted recently.

Coursera has redefined MOOC to be Monthly Open Online Course, as most of the courses now are running a new session every month, and even allowing students to switch sessions if they miss any deadline, helping procrastinating students strengthen their habit of ignoring deadlines. With so many ongoing sessions at once, course sizes have decreased dramatically and the discussion forums are now for roam, as students stare at the blank screen and wonder why nobody complies when the professor asks them to write down their thoughts in the forums. Forum posts are never kept from session to session, strangling the only way left to revive the forums. The collaboration with Coursera is gone too, and the Coursera experience is now predominantly solitary. Continue reading “The Deterioration of Coursera”

Top 6 Online Course Professors

This is an ranked up-to-date list that includes my favorite professors after taking more than 40 online courses. Professor quality is judged from how provocative, engaging, and clear the lectures are. The number and length of available courses is also considered. The amount of study materials available, video quality, and interest in subject are not directly considered.

1. Robert Sapolsky, Biology professor at Stanford University


Robert Sapolsky is best known for his Human Behavioral Biology course on YouTube. He has three other paid courses available on He studies human behavior by drawing comparison from baboons and using neuroscientific, evolutionary, and endocrinal approaches, which shows the different ways of looking at human behavior only complement each other instead of being contradictions.

Sapolsky is hands-down the god in conveying passion through lectures. His tone of speaking every sentence makes you really want to hear the next sentence yet the shock of the information he throws at you makes you want to pause and think. Just hearing his voice will cure depression and anxiety.

No whiteboard notes or study materials; yet he had ignited my interests in behavioral sciences and first introduced me to the field of complex systems. After taking his Human behavioral Biology course, the non-majors courses I took in the three semesters left in college increased to about 60%.
