Coursera and am favourably impressed with the way the course has been done. I believe not all courses they offer at Coursera are as good as this - more on this later. The video lectures were short (10-25 mins) and engaging with the lecturer speaking as in he was in a small informal group and punctuating the lecture with pictures, questions, video clips etc. There were downloadable readings. There were weekly assignments which were diverse, imaginative and not too academic. There were very active forums - possible because of thousands of students all doing the course together. There was also a series of customised Google Hangout sessions with other students in groups of 4 or 5.
The topic being psychology made possible a style which would be more difficult with the hard sciences but it seems to be near the cutting edge of online learning. Recommended.

report has now been released and consists of 97 pages.
"Preliminary results indicate 241 species of plants, 302 birds, 150 species of fish, 34 reptiles, 25 amphibians, 23 small mammals and over 300 species of insects were encountered during the two week expedition."Also see this very readable write-up of this in Caribbean Beat. Plus there is this Guyana Times report from a local perspective.

The problem is often that your browser cannot reach the GTT-provided name server (DNS) which is required to translate the website name into the internet (IP) address needed to reach it. The permanent solution is to provide a public name server address to your computer to meet the need.
A commonly used public name server address is that of Google: 18.104.22.168 or 22.214.171.124.
To add this name server address to your computer please see one of these tutorials below. Note - this needs some experience so ask for help if you are unsure. You can cause more trouble if you make mistakes.

You can diagnose the problem more accurately by pasting the following address into your browser where I use the IP address directly not the name so DNS is not used:
If you get a webmail login site (this is just a random site to use as a test) then you do have an internet connection but the DNS may not be working so try the above solution. If you get nothing then you have some other problem or GTT does.
Another, temporary, solution is to close down your PC and modem, restart and hope for the best...

From an article in The Atlantic:
"...this might be the key to their findings: Take notes by hand, and you have to process information as well as write it down. That initial selectivity leads to long-term comprehension."
Secondly getting the active participation of students is more effective than long lectures. No surprise really, the trick is how... the article does give some clues. One more thing - putting the lecture on a computer does not improve learning. From the article in Science :
"A new study finds that undergraduate students in classes with traditional stand-and-deliver lectures are 1.5 times more likely to fail than students in classes that use more stimulating, so-called active learning methods."

"The world needs a Plan B on climate change because politicians are failing to reduce carbon emissions, according to a UN report.
It warns governments if they overshoot their short-term carbon targets they will have to cut CO2 even faster in the second half of the century to keep climate change manageable"
And the Washington Post reports:
"At a meeting in Berlin, the U.N. Intergovernmental Panel on Climate Change (IPCC) on Sunday released a report that found that nations still have a chance to fulfill the goal but must aggressively turn away from relying largely on fossil fuels such as coal for energy and replace them with cleaner energy sources such as solar and wind power. To reach their target of 3.6 degrees (2 degrees Celsius) over preindustrial levels, nations must work together to lower emissions 'by 40 to 70 percent' of what they were in 2010, the report said."
