  Mini-languages: A Way to Learn Programming Principles
Since general-purpose programming languages are oriented on number and symbol processing, the first possible problems used in teaching the language are far from the students' everyday experience and are not attractive for them.
Josef was designed at the same time as Karel and its philosophy is a combination of Logo and the ideas used in Karel namely the idea of a rich microworld of Logo and the idea of preparing the user for programming constructs of conventional languages as in Karel.
The program should typically be executed one instruction at a time, while the interpreter highlights programming constructs in the source code as they are being executed and the effect is simultaneously shown in the microworld.

 Why We Program Karel   (Site not responding. Last check: 2007-11-01)
Programming a computer in a language like Pascal requires precise sequencing of steps, one after the other, choosing which steps to follow in certain cases, and controlling the repetition of certain steps, in the process of solving a problem.
Karel is a teaching tool that presents the concepts in a visual way, that is less abstract than programming in Pascal.
Karel the Robot was introduced by Richard Pattis in his book Karel the Robot: A Gentle Introduction to the Art of Programming with Pascal, John Wiley and Sons, Inc., 1981.

 Bob Walton's New Programming Language
The main goal of this language is to be usable by commercial programmers, while being accessible to average high school students, who should be able to modify and augment parts of programs written in the language.
The second effort to define the new language centered on trying to teach students who had difficulties learning to program, in order to find out at least roughly what programming language features would and would not work with the high schoolers for whom the new language was in part intended.
The mechanism here was to teach introductory programming at Suffolk University for a few years, and to write a textbook, or rather a series of revisions of a textbook, and to develop companion programming environments.

A language concept is called “first class”1 when it can be used freely in the programs in all contexts in which this would be reasonable.
C# iterators provide a language mechanism which is extensible in that it provides a means for dealing with the common case of sequencing through a collection of objects and applying a function to the contents of the collection.
