How do we get people to understand programming? Khan Academy recently launched an online environment for learning to program.
Learning about "for" loops is not learning to program, any more than learning about pencils is learning to draw. People understand what they can see. If a programmer cannot see what a program is doing, she can't understand it.

The programming "environment" is the part that's installed on the computer. The programming "language" is the part that's installed in the programmer's head. This essay presents a set of design principles for an environment and language suitable for learning. The environment should allow the learner to: The features are not the point We often think of a programming environment or language in terms of its features -- this one "has code folding", that one "has type inference".
This is like thinking about a book in terms of its words -- this book has a "fortuitous", that one has a "munificent".
What matters is not individual words, but how the words together convey a message. Likewise, a well-designed system is not simply a bag of features. A good system is designed to encourage particular ways of thinking, with all features carefully and cohesively designed around that purpose.Mar 24, · A RELATIVELY new field, called interpersonal neurobiology, draws its vigor from one of the great discoveries of our era: that the brain is constantly rewiring itself based on daily life.
Essay The Immune System (Immune) The immune system is what protects the body from any potentially harmful substances by recognizing and responding to antigens. Antigens are typically protein substances are on the surface of cells, viruses, fungi, or bacteria.
- Stress and the Immune System AIM: to study the effect of stress (exams) on the immune system. They wanted to test the hypothesis that stress reduces immunity by seeing if there is a difference in immune response between two conditions (high and low stress).
Nutrition: Immune System and Vitamin Essay. terms of enhancing immune response is unclear. Vitamin B6. Several studies have suggested that a vitamin B6 deficiency can depress aspects of the immune response, such as lymphocytes’ ability to mature and spin off into various types of T and B cells.
A Female Senator Figured Out One Small Way to Fight Sexual Harassment We still have a distance to go, of course, but it’s a meaningful start.
The immune system is also known as the human defence system; it is made up different cells, tissues, proteins and organs which come together to play different roles in protecting the body from pathogens which are brought about by microorganisms such as: bacteria, parasites and viruses.
