Most of the students where I teach have time in their computer labs to surf the web or play flash games. The IT department, in order to conserve bandwidth and filter "inappropriate material", need to block most games. Since most games are just mind-numbing wastes of time, most teachers support this. Students looking for games will scour the web searching for game sites that aren't blocked. As soon as one game site is discovered, the URL spreads like wildfire before the site is blocked in the next few days. The cycle repeats itself ad nauseum.
Seeing the problem from both sides, I decided to make an "approved games list" of games that at least feature some academic merit. I understand that games can be beneficial and educational while still being enjoyable. I asked my Computer Science class to find games they enjoy and add them to my games list. They needed to list the educational lessons found within the game and the supporting TEKS on my games list.
The end result has grown into "Mr. Gober's Games". Several students use the site daily and it has received the approval of administration.
Ideally, the next step will be to house the site on the school network to reduce the bandwidth load and increase response speed for the user.
Recently I have added a page to add games, a method to report broken or inappropriate games and a new ratings system. The ratings system was my first successful foray into AJAX. I've attempted AJAX before but came up short. Fortunately jQuery made the effort much easier by abstracting most of the work for me. So, take a look at Mr Gober's Games and have fun - don't forget to vote for your favorites!
