Kate Russell's weekly review of the best apps and websites.
The internet is a powerhouse of great educational tools that make learning fun and free for all. Busuu is a social learning platform that teaches 12 languages using colourful buttons, clicks and drag and drop interactivity to learn vocabulary, dialogue and writing.
There are lots of initiatives to encourage youngsters to learn coding right now, and the internet is the perfect forum for this. Code.org is a great starting point, serving up practical lessons you can complete in your bedroom that give you real results really quickly.
The Year of Code is a project running this year that has high hopes to nurture the programmers of the future. The site has great support, advice and loads of other resources where you can pick up computer skills free of charge.
Teachers or parents who want to have a hand in their child's education can build their own quizzes with GetKahoot. Using it, is as simple as dragging and dropping the elements, such as images, video and text, into the creation tool.
If you are still hungry for education resources this blog by a teaching professional has compiled over 190 free teaching and learning activities.
On 30 March Digital Unite's Spring Online digital inclusion campaign begins, which helps thousands of older and less confident computer users take their first steps with digital technology.
Some children (and adults) would rather play video games than study, but perhaps that is not as bad as you think. This week's video comes from ASAPScience and investigates whether playing video games can make you smarter.

The article talks about a new website call code.org that was created to encourage people to learn how to code in an interactive way. the Year of Code is a project that tries to help the nature of the future programmers, it provides support, advice and loads of other resources to pick computer skills free.
Scientists 'print' new eye cells

Scientists say they have been able to successfully print new eye cells that could be used to treat sight loss.
The proof-of-principle work in the journal Biofabrication was carried out using animal cells.
The Cambridge University team says it paves the way for grow-your-own therapies for people with damage to the light-sensitive layer of tissue at back of the eye - the retina.
More tests are needed before human trials can begin.

Clara Eaglen of the RNIBThis is a step in the right direction as the retina is often affected in many of the common eye conditions, causing loss of central vision which stops people watching TV and seeing the faces of loved ones”
At the moment the results are preliminary and show that an inkjet printer can be used to print two types of cells from the retina of adult rats―ganglion cells and glial cells.
These are the cells that transmit information from the eye to certain parts of the brain, and provide support and protection for neurons.
The printed cells remained healthy and retained their ability to survive and grow in culture.
Retinal repair
Co-authors of the study Prof Keith Martin and Dr Barbara Lorber, from the John van Geest Centre for Brain Repair at the University of Cambridge, said: "The loss of nerve cells in the retina is a feature of many blinding eye diseases. The retina is an exquisitely organised structure where the precise arrangement of cells in relation to one another is critical for effective visual function.
"Our study has shown, for the first time, that cells derived from the mature central nervous system, the eye, can be printed using a piezoelectric inkjet printer. Although our results are preliminary and much more work is still required, the aim is to develop this technology for use in retinal repair in the future."
They now plan to attempt to print other types of retinal cells, including the light-sensitive photoreceptors - rods and cones.
Scientists have already been able to reverse blindness in mice using stem cell transplants.
And there is promising work into electronic retina implants implants in patients.
Clara Eaglen, of the RNIB, said: "Clearly it's still at a very early stage and further research is needed to develop this technology for use in repairing the retina in humans.
"The key to this research, once the technology has moved on, will be how much useful vision is restored.
"Even a small bit of sight can make a real difference, for some people it could be the difference between leaving the house on their own or not.
"It could help boost people's confidence and in turn their independence."
Prof Jim Bainbridge of London's Moorfields Eye Hospital said: "The finding that eye cells can survive the printing process suggests the exciting possibility that this technique could be used in the future to create organised tissues for regeneration of the eye and restoration of sight.
"Blindness is commonly caused by degeneration of nerve cells in the eye. In recent years there has been substantial progress towards the development of new treatments involving cell transplantation."
The article is about studies that are being analize to trat the blindness problems. the idea of scientist is to repair the eyes by using new printed eyed cells. there aim is to develope this technology for use in retinaal repair in the future.
