Programming 101 - The 5 Basic Concepts of any Programming Language - How to Program with Java
First off, I’d like to say that I’m writing these preliminary posts in a way that I’ll assume you have very little knowledge in programming. I want this content to provide anyone “walking in off the street” the knowledge to be able to write their first program with the Java programming language with as little pain as possible. So, let’s get started with our first topic: The 5 basic concepts of any programming language. You might say, “Why are we talking about any programming language? I thought this was about Java”. So here are the 5 basic concepts of any programming language: I recognize that these words probably look foreign to you, but don’t worry, I’ll do my very best at taking the mystery out of them. What is a variable? Variables are the backbone of any program, and thus the backbone of any programming language. This concept is extremely powerful in programming and is used constantly. What the heck are String, Integer and Double? Excellent question! Plenty of Ways to Learn

How To Teach Programming To Kids This is R. L. Shanker’s submission for the HP Magic Giveaway. Feel free to leave comments for this article as you see fit – your feedback is certainly welcomed! If you’d like to submit your own how-to, what-is, or top-five list, you can send it to me. You probably know a kid who is bitten by the computer bug – could be your son or your nephew or your friend’s kid. In this how-to, I review two tools that have been tested successfully in homes/schools across the world. Age 6-9 years Scratch: A product of the Lifelong Kindergarten Group at MIT, Scratch provides kids with an exciting environment to create and share computer applications. Age: 10-14 years Phrogram. The only downside is that Phrogram is not a freeware. Age: 15+ years The kid is now ready for the big league; it is time to respect his intellect and let him take the deep plunge. Final thoughts Engage, engage and engage. The actual choice of software or platform is a subjective one – it depends on the student and the tutor.

Brandieself added: Free JavaScripts, tutorials and tools - Onlinetools.org Happy Nerds - Programming Links for Kids TclX ObjCmdWrite Table of Contents Name TclCommandWriting - Writing C language extensions to Tcl. Overview This document is intended to help the programmer who wishes to extend Tcl with C language routines. Information on the available C interface routines to Tcl can be found in the *.3 manual pages in the doc directory of the baseline Tcl dis-tribution, and in the *.3 manpages in the doc directory of Extended Tcl. Tcl ObjectSystem With the release of Tcl version 8, Tcl has a new system for managing Tcl values internally. Although the object system has almost no effect at all on how the Tcl programmer uses Tcl, the object system’s C interfaces to strings, inte-gers, lists, etc., have changed considerably. We have chosen, then, to rewrite the Command Writer’s manpage, which has been shipping with Extended Tcl for a number of years, to produce this new version based on the new object system. a Simple CExtension A simple C extension to Tcl is now presented, and described below: #include tcl.h" void *clientData;

Teaching kids how to write computer programs, by Marshall Brain by Marshall Brain Quick Intro - If you are looking for a quick and easy way to teach your kid a real programming language, without downloading anything or buying anything, try these Python tutorials. Your kid will be writing and modifying code in just a few minutes. Marshall Brain's quick and easy Python tutorials Let's say that you have children, and you would like to help them learn computer programming at a youngish age. As the father of four kids, I have tried to approach it from several different angles. Let's start with a something important: Every kid is different. The second thing to realize is that real analytical skills often don't start appearing until age 11 or 12 or 13 in many kids, so expecting huge breakthroughs prior to that may be unrealistic. That being said, there are lots of fun things you can try as early as five or six... Games Let's start with a few games. Then there is this game, which actually does a very good job of teaching simple programming skills: Python for Kids
