I don't think that there is anyone who doesn't know Khan Academy, at least there shouldn't be. Nevertheless not everyone knows that there is nothing difficult in setting up the tools to do this.

John Biggs (East Coast Editor of TechCrunch presented 4 Step Method about successful international blogging. 

At the beginning John presented universal rules for successful blogging that are: write specifically about what you're good at and gain traction inside your country and be passionate about what are you blogging about.

At school we were shown black smoker lungs. That shocking view was to prevent all of us from starting to smoke. Few years later we knew that it was quite a good way to socialize, but after some years we have become, in the worst case, social smokers.

Time goes by and black lungs are probably not enough so The Cancer Society in Filnand figured out that engaging elearning might be good way to teach about all what is bad in smoking.

From e-learning perspective the most important things are:

1. Minimalistic approach to the design. 
2. No request for sign up/in 
3. Amazing usability. The only thing that you have to do is to click specific body parts, move the trigger back and forth and read descriptions.
4. Mobile support

How to Generate Good Ideas from Column Five on Vimeo.

How are good ideas generated? They aren’t simply lying around like seashells on a beach waiting for us to pick them up nor are they so random. Good ideas are the result of the focused action that takes place in our brains. With a bit of stretching the laws of physics and a lot of imagination, we set out to craft a story about how all those bits and pieces that pass through our brains can become good ideas.

Percentage Calculator is a tool that lets you do a simple calculation: how many percent of X is Y? The tool is pretty straightforward. All you need to do is fill in two fields and the third one will be calculated for you. Other than being helpful with learning percentages and fractions, Percentage Calculator is handy in many different situations. For example, you may calculate an amount of income tax. That is pretty much all you need to know.

Percentage Calculator is a tool that is meant to be used for two purposes: for solving and learning percentages. The former is obvious: many people need a simple tool that will tell them what is x% of y or how many % of foo is bar. It is so simple that there are literally dozens of sites that do it (mine is way cooler, though :-) ).

The other goal of the site - to help kids learn percentages - is a bit trickier. I designed the calculator with a few ideas in mind:

1. In a 3-field formula user inputs any 2 of the 3 numbers. The third one is calculated for him. 
2. Calculations are done dynamically as user types in his numbers. There is no need to click on a submit button. This way a student sees what is going on as he/she "constructs" the sentence. Also, it is a very quick process (press a single key and see a new result), thus encourages the student to keep experimenting. 
3. There are four forms-sentences that user can fill in: x% of y is z, z is x% of y, fraction z / y is the same as x% and z is q% decrease/increase from y. While the student fills in one form, all the others are completed for him - this way he/she sees that these sentences are in fact the same (or almost the same in the case of 4th sentence). 
4. Few more related formulas are shown, to further show how provided numbers "work" with each other. 
5. The tool can be easily customized embedded on external websites - it is a good way to add an interactive element to otherwise static online lectures, right?
