Millions of people have signed up for Massive Open Online Courses, known as MOOCs. Early studies show that the majority of those who have signed up already have a college degree, and most do not opt to pay for a certificate to prove they passed the class. Put simply, they’re not looking to get college credit in any way. So I’m curious to dig deeper into what motivates these online “students.”
I am late to post because I’ve been digging around for a killer data set on this. I’ve made requests to HarvardX and to some researchers who have a large MOOC dataset, but so far no one has been willing to share their raw numbers. But HarvardX has published some demographic and survey data (not much). My sense, though, is that their data does not answer the question very well (most MOOC surveys only offer a few multiple choices on motivation).
So for the assignment, I’m focusing on playing around with fuzzier “data” – the student postings to forums in a MOOC. In many MOOCs, students post short introductions in the forums at the beginning of the term, usually saying why they are taking the course. I’ll analyze the intro discussion postings in one MOOC and group them into broad categories (my categories won’t capture everything, but there are definitely clear patterns in the responses).
My plan is to pick an astronomy course on edX that just started. https://courses.edx.org/courses/ANUx/ANU-ASTRO1x/1T2014/discussion/forum/i4x-edx-templates-course-Empty/threads/533080e801772bb02e00087f
There are only about 200 intro posts, so it should be do-able in the short time frame.
I plan to pull out one student post that is the best example of each category I create. So the interface will be a simple pie chart with the percentages of each reason for taking a MOOC, but then when you click on a specific group/color, you’ll be taken to that person’s intro post so you viewers can “meet” them.
I’m certainly open to suggestions on tools, critique, etc.

There are many types of tiles available nowadays.
The method of tile cleaning will depend more on the tile type.
However there are couple of things to be
followed to add the sheen and glow of the tiles.
Do the regular floor cleaning
Clean the spills as soon as they occur
It is very crucial to clean dirt and water too as soon as they are split to prevent the
stains. Place a doormat which helps in reduction of mud or
dirt entering through footsteps.
There are basically following tile floors where in one will use the tile and grout cleaning process, types of tiles are as follow –
Ceramic
Porcelain
Stone
Porcelain Tile cleaning
Porcelain tiles maintenance is not difficult if the surface is
cleaned regularly. The surface can be vacuum cleaned every day
or just sweep it. The wet mopping is required once in a week.
Use of mild floor cleaners will do for the mopping.
One can make it at home by mixing vinegar and water.
Ceramic Tile Cleaning
The rule is followed here as well; remove the dirt as
soon as possible. Vacuum clean the tiles every day or a simple broom can be used.
Plain water or the special ceramic tile cleaners can be used for
the wet mopping.
Stone Tile Cleaning
One need to be careful while cleaning the tiles made of stones as
they are natural minerals. Never use harsh floor cleaners.
Sweep or vacuum clean. After using any floor cleaner use
a dry mop to soak any type of liquid residue.
Grout Cleaning
Along with the tile cleaning it is very important
to regularly clean the grout, i.e. the lines between the tiles.
Hence tile and grout cleaning goes simultaneously.
Grout is porous in nature and attracts dirt, grease etc.
The surface looks shabby if the grout is unclean. It can also
be a cause of mildew or mould in the damp areas like bathrooms.
It is best to have a seal (colour or clear) on the grout which will not only protect the surface but also acts as an anti-fungal agent.
Many a times it gets difficult to maintain the floor due
to hectic working schedules. Hence we come in picture and provide the tile and grout cleaning services
to our clients at a very affordable price. Moreover
the price depends on the type of the tiles, number of tiles and size of the tiles to be cleaned.
Following steps are followed for the tile and grout cleaning
after you contact us-
Pre inspection of the tiles and floor.
Shifting of the furniture, if any, from that space.
Dry Sweeping of the surface
Application of the suitable cleaning solution.
Cleaning the surface with a soft pad.

We have our experts who carry special tools to do the tile and grout cleaning;

Plumbing Repairs That Require a Professional Plumbing Service
Plumbing repair work can encompass many things, such as mending hot water heaters, or fitting new faucets in bathrooms.
On the internet, there is information about how to do many kinds of plumbing jobs.
Understandably, most people want to avoid hiring a plumber to carry
out maintenance or repair work, which they could perform themselves.
Nonetheless, considerable precision and expertise is
needed to implement the majority of plumbing tasks.
Even a basic error, like failing to seal a pipe tightly
enough, could cause leaks that result in expensive water damage and high water bills.
Leaks could cause mold to develop in your house as well.
You should hire plumbing services, whenever severe
problems with your plumbing system arise. If you don’t do this,
you might end up making the problem even worse.
The hot Water Stops Working
It can be difficult to identify the cause of this problem, unless you have a leaking water tank.
Leaks can appear anywhere in your system, due to a range of factors.
Issues with gas heaters can involve thermocouple ignition systems
and burners. Issues with electrical heaters can involve heating elements, bad
overload switches, malfunctioning thermostats, and blown fuses or
circuit breakers.
The Water Pressure in Your Home is too low
There are several things that can cause this problem.
Examples include badly designed supply lines, low water pressures from wells or city supplies, and
water line blockages (such as debris or rust). A reputable plumber
will diagnose the cause of the problem, and tackle
it effectively.
The Sewer Line Backs up
In all likelihood, if you encounter a sewer line stoppage, the
line will have a plug in it that leads out to the primary sewer.
Frequently, this is caused by tree roots.
Large sewer rodding machines can be rented, however
they might harm the sewer lines or drain. Contact a drain cleaning company
or plumber. If they experience problems, they will do
the repair work.
Installing a new Water Heater
Ideally, you should avoid trying to install a new heater
on your own. A good plumber will transport the new heater to your storage
area, connect it and ensure that it functions correctly.
He or she can get rid of your old heater too.
Severe Damage to Water Lines
It is a time consuming process to fix damage to water
lines. Normally, this occurs due to freezing. Hire a plumber, so that you don’t have to
interrupt your regular schedule.
Pipe Freezing
If you have frozen pipes, they may have cracks in them already
— in which case you need a plumber. Even if your pipes don’t have cracks in them, hiring a plumber still
might be sensible. Rather than thawing frozen pipes, some plumbers just replace certain sections of them.
Any kind of plumbing problem can represent a threat to property or health.
Therefore, these problems need to be addressed straightaway.
Locate some good plumbing repairs services, and contact them if you encounter any of the above situations.

Today, I went to the beach front with my
kids. I found a sea shell and gave it to my 4 year old daughter and
said “You can hear the ocean if you put this to your ear.” She placed
the shell to her ear and screamed. There was a hermit
crab inside and it pinched her ear. She never wants to go back!
LoL I know this is entirely off topic but I had to tell someone!
