if you're not the one controlling your learning, you're not going to learn as well.

The bottom line is, if you're not the one controlling your learning, you're not going to learn as well.

IN 1999, SUGATA Mitra
was chief scientist at a company in New Delhi that trains software developers. His office was on the edge of a slum, and on a hunch one day, he decided to put a computer into a nook in a wall separating his building from the slum. He was curious to see what the kids would do, particularly if he said nothing. He simply powered the computer on and watched from a distance. To his surprise, the children quickly figured out how to use the machine.

Over the years, Mitra got more ambitious. For a study published in 2010, he loaded a computer with molecular biology materials and set it up in Kalikuppam, a village in southern India. He selected a small group of 10- to 14-year-olds and told them there was some interesting stuff on the computer, and might they take a look? Then he applied his new pedagogical method: He said no more and left.

Over the next 75 days, the children worked out how to use the computer and began to learn. When Mitra returned, he administered a written test on molecular biology. The kids answered about one in four questions correctly. After another 75 days, with the encouragement of a friendly local, they were getting every other question right. “If you put a computer in front of children and remove all other adult restrictions, they will self-organize around it,” Mitra says, “like bees around a flower.”

A charismatic and convincing proselytizer, Mitra has become a darling in the tech world. In early 2013 he won a $1 million grant from TED, the global ideas conference, to pursue his work. He’s now in the process of establishing seven “schools in the cloud,” five in India and two in the UK. In India, most of his schools are single-room buildings. There will be no teachers, curriculum, or separation into age groups—just six or so computers and a woman to look after the kids’ safety. His defining principle: “The children are completely in charge.”



Mitra argues that the information revolution has enabled a style of learning that wasn’t possible before. The exterior of his schools will be mostly glass, so outsiders can peer in. Inside, students will gather in groups around computers and research topics that interest them. He has also recruited a group of retired British teachers who will appear occasionally on large wall screens via Skype, encouraging students to investigate their ideas—a process Mitra believes best fosters learning. He calls them the Granny Cloud. “They’ll be life-size, on two walls” Mitra says. “And the children can always turn them off.”


Mitra’s work has roots in educational practices dating back to Socrates. Theorists from Johann Heinrich Pestalozzi to Jean Piaget and Maria Montessori have argued that students should learn by playing and following their curiosity. Einstein spent a year at a Pestalozzi-inspired school in the mid-1890s, and he later credited it with giving him the freedom to begin his first thought experiments on the theory of relativity. Google founders Larry Page and Sergey Brin similarly claim that their Montessori schooling imbued them with a spirit of independence and creativity.

correction forumula for HIGH PCV /HCT in coagulation tests.

Correcting high hematocrit coagulation


    Packed cells up this high indicates a high hematocrit (ᡯ) the patient may need a custom draw. 
    This hematocrit  is 40.5%


    Use the following formula to customize a collection for a patient with a hematocrit greater than 55%


    Step 1. Solve for “a” where a= 3.2 * (100-the patient’s hematocrit)/ 55 
    Step 2. Solve for “y” where y = a * 0.3 / 3.2
      y is the volume of 3.2% citrate needed to add
      to 2.7 ml of patient’s blood.


      Example: Let’s say the patient has a Hct of 63% 
          Step 1. Solve for “a” where a= 3.2*(100-63)/ 55
          a= 2.15
            Step 2. Solve for “y” where y = 2.15 * 0.3 / 3.2
            y= 0.2
              You would now use 0.2ml of 3.2% citrate for
              2.7 ml of patient’s blood.
