List of educational programming languages

Short description: none

An educational programming language is a programming language that is designed mostly as an instrument for learning, and less as a tool for writing programs to perform work.

Types of educational programming languages

Assembly languages

Originally, machine code was the first and only way to program computers. Assembly language was the next type of language used; thus, is one of the oldest families of computer languages in use today. Many dialects and implementations are available, usually some for each computer processor architecture. It is very basic and termed a low-level programming language. It is one of the more difficult languages to work with being untyped and rigid. Several simplified dialects exist for education.

Low-level languages must be written for a specific processor architecture and cannot be written or taught in isolation without referencing the processor for which it was written. Unlike higher-level languages, using an educational assembly language needs a representation of a processor, whether virtualized or physical. Assembly is used for learning about fundamental computer processor operation.

• Little Man Computer (LMC) is an instructional model of a simple von Neumann architecture computer with all the basic features of modern computers. It can be programmed in machine code (usually decimal) or assembly. It is based on the concept of having a little man locked in a small room. At one end of the room are 100 mailboxes as memory; each can hold a three-digit instruction or data. At the other end of the room are two mailboxes labeled INBOX and OUTBOX which receive and emit data. In the middle of the room is a work area with a simple two-function (add and subtract) calculator called the Accumulator and a resettable counter called the Program Counter. The counter is similar to what a doorperson uses to count how many people have entered a facility; it can count up 1 or can be reset to 0. As specified by the von Neumann architecture, memory holds both instructions and data. The user loads data into the mailboxes and then signals the little man to begin executing.
• Next Byte Codes (NBC) is a simple language with assembly language syntax that is used to program Lego Mindstorms NXT programmable bricks. The command line compiler emits NXT-compatible machine code and supports Windows, Mac OS X and Linux.
• Little Computer 3 (LC-3), is an assembly language with a simplified instruction set, but can be used to write moderately complex assembly programs and is a theoretically viable target for C compilers. It is simpler than x86 assembly but has many features similar to those in more complex languages. These features make it useful for teaching basic programming and computer architecture to beginning college computer science, and computer engineering students, which is its most common use.
• DLX is a reduced instruction set computer (RISC) processor architecture by the main designers of the MIPS and the Berkeley RISC designs, two benchmark examples of RISC design. DLX is essentially a cleaned-up, simplified MIPS, with a simple 32-bit load/store architecture. It is widely used in college-level computer architecture courses.
• MIX and MMIX are hypothetical computers used in Donald Knuth's monograph, The Art of Computer Programming (TAOCP). The MIX computer systems are designed to educate individuals about what goes inside a computer through its use of a basic and comprehensible machine language. Despite its simplicity, the MIX system handles complex tasks that are found in typical high-performance general-purpose computers. MIX is a hybrid programmable in binary and decimal numbers; most programs written for it will work using either form. Software implementations for MIX and MMIX have been developed by Knuth and made freely available. Several versions of both emulators exist. MIX is a 1960s-style computer. It is superseded by MMIX, a newer modern computer architecture, a 64-bit RISC instruction set architecture (ISA). For MMIX, Knuth collaborated with the architects of the MIPS and Alpha ISAs.

BASIC variants

BASIC (which stands for Beginner's All-purpose Symbolic Instruction Code) was invented in 1964 to provide computer access to non-science students. It became popular on minicomputers during the 1960s and became a standard computing language for microcomputers during the late 1970s and early 1980s. The goals of BASIC were focused on the need of learning to program easily:

• be easy for beginners to use,
• be interactive,
• provide clear and friendly error messages,
• respond quickly, and
• do not require an understanding of computer hardware or operating systems.

What made BASIC particularly useful for education was the small size of programs that could illustrate a concept in a dozen lines. BASIC continues to this day to be frequently self-taught with excellent tutorials and implementations.

BASIC offers a learning path from learning-oriented BASICs such as Microsoft Small Basic, BASIC-256 and SiMPLE, to more full-featured BASICs like Visual Basic .NET and Gambas.

• Microsoft Small Basic is a restricted version of Visual Basic designed as a first language, "aimed at bringing 'fun' back to programming". The language is explicitly quite small with only 15 intuitive keywords. By including object-specific libraries for things of general interest to children, children can create entertaining, interactive programs, on the net or on the desktop. For example, with 6 lines of code, it is possible to demonstrate a random network image viewer using Flickr as the source. The system utilizes the Microsoft Visual Studio IDE to provide auto-completion and context-sensitive help.
• Basic-256 an easy-to-use version of BASIC designed to teach anybody the basics of computer programming. It uses traditional BASIC control structures (gosub, for loops, goto) for ease of understanding program flow control. It has a built-in graphics mode that allows children to draw pictures on the screen after minutes.
• SiMPLE is a programming development system that was created to provide easy programming abilities for everybody, especially non-professionals. It is somewhat like AppleSoft BASIC. It is compiled and lets users make their own libraries of often-used functions. "Simple" is a generic term for three slightly different versions of the language: Micro-SIMPLE (uses only 4 keywords), Pro-SiMPLE, and Ultra-SiMPLE (using 23 keywords).
• Hot Soup Processor is a BASIC-derived language used in Japanese schools.
• TI-BASIC is a simple BASIC-like language implemented in Texas Instruments graphing calculators, often serving as a student's first look at programming.
• SmallBASIC is a fast and easy-to-learn BASIC language interpreter ideal for everyday calculations, scripts and prototypes. It includes trigonometric, matrix, and algebra functions, a built in IDE, a powerful string library, system, sound, and graphic commands, and a structured programming syntax.

C based

• Ch is a C/C++ interpreter designed to help non-CS students to learn math, computing and programming in C and C++. It extends C with numerical, 2D/3D graphical plotting and scripting features.

Java-based

• NetLogo, written in Java and Scala, is a development environment for building and exploring scientific models, specifically agent-based models. It is in widespread use both in science research (Science papers using NetLogo) and in educational contexts, including elementary, secondary schools, universities and museums.

Lisp-based

The name LISP derives from "LISt Processing language". Linked lists are one of the languages' major data structures, and Lisp source code is made of lists. Thus, Lisp programs can manipulate source code as a data structure, giving rise to the macro systems that allow programmers to create new syntax or even new domain-specific languages embedded in Lisp. Therefore, Lisps are useful for learning language design and creating custom languages.

A reasonable learning path would be Logo followed by any educational variant such as Scheme or newLISP, followed by a professional variant such as Common Lisp.

• Logo is a language that was specifically designed to introduce children to programming. The first part of learning Logo deals with "turtle graphics" (derived from turtle robots) used as early as 1969 with proto-Logo. In modern implementations, an abstract drawing device, called the turtle, is used to make programming for children very attractive by concentrating on doing turtle graphics. Seymour Papert, one of the creators of Logo, was a major thinker in constructionism, a variety of constructivist learning theories. Papert argued that activities like writing would naturally be learned by much younger children provided that they adopted a computing culture. Logo was thus designed not only to teach programming, and computing concepts, but to enhance a child's entire well-being in a culture increasingly dominated by technology, "more important than having an early start on intellectual building, is being saved from a long period of dependency during which one learns to think of learning as something that has to be dished out by a more powerful other...Such children would not define themselves or allow society to define them as intellectually helpless." It has been used by children as young as 3 years old and has a track record of 30 years of success in education. Since Logo is actually a streamlined version of Lisp with more advanced students, it can be used to introduce the basic concepts of computer science and even artificial intelligence. Logo is widely available on virtually every platform, in both free and commercial versions.

Scala-based

• Kojo is an interactive desktop development environment developed primarily for educational purposes application that runs on Windows, Linux, and OS X. It is a learning environment, with many different features that help with the exploration, learning, and teaching of concepts in the areas of computer programming and critical thinking, math and science, art, music, and creative thinking, computer and internet literacy.

Smalltalk-based

As part of the One Laptop per Child project, a sequence of Smalltalk-based languages has been developed, each designed to act as an introduction to the next. The structure is Scratch to Etoys to Squeak to any Smalltalk. Each provides graphical environments which may be used to teach not only programming concepts to kids but also physics and mathematics simulations, story-telling exercises, etc., through the use of constructive learning. Smalltalk and Squeak have fully featured application development languages that have been around and well respected for decades; Scratch is a children's learning tool.

• Scratch is a visual language based on and implemented in Squeak. It has the goal of teaching programming concepts to children and letting them create games, videos, and music. In Scratch, all the interactive objects, graphics, and sounds can be easily imported to a new program and combined in new ways. That way, beginners can get quick results and be motivated to try further. The Scratch community has developed and uploaded over 3,000,000 projects. It is developed by the Lifelong Kindergarten group at MIT Media Lab.
• Etoys is based on the idea of programmable virtual entities behaving on the computer screen. Etoys provides a media-rich authoring environment with a simple, powerful scripted object model for many kinds of objects created by end-users. It includes 2D and 3D graphics, images, text, particles, presentations, web pages, videos, sound and MIDI, the ability to share desktops with other Etoy users in real-time, so many forms of immersive mentoring and play can be done over the Internet. It is multilingual and has been used successfully in United States , Europe, South America, Japan , Korea, India , Nepal, and elsewhere. The program is aimed at children between the ages of 9-12.

• Squeak is a modern, open-source, full-featured implementation of the Smalltalk language and environment. Smalltalk is an object-oriented, dynamically typed, reflective language created to underpin the "new world" of computing exemplified by "human-computer symbiosis". Like Lisp, it has image-based persistence, so everything is modifiable from within the language itself (see Smalltalk). It has greatly influenced the industry introducing many of the concepts in object-oriented programming and just-in-time compilation. Squeak is the vehicle for a wide range of projects including multimedia applications, educational platforms and commercial web application development. Squeak is designed to be highly portable and easy to debug, analyze, and change, as its virtual machine is written fully in Smalltalk.

Pascal

• Pascal is the most well-known language that was designed with education in mind. From the late 1970s to the late 1980s, it was the primary choice in introductory computer science classes for teaching students programming in both the US and Europe. Its use for real-world applications has since increased, and regarding it as a purely educational language has since become somewhat controversial.

Other

• CircuitPython is a beginner-oriented version of Python for interactive electronics and education.
• Rapira is an ALGOL-like procedural programming language, with a simple interactive development environment, developed in the Soviet Union to teach programming in schools.
• Src is a tactile offline programming language embedded in an educational card game.

• Alice is a free programming software designed to teach event-driven object-oriented programming to children. Programmers create interactive stories using a modern IDE interface with a drag and drop style of programming. The target audience is incoming college freshmen although most children with computer experience will find it entertaining and educational. Story Telling Alice is an Alice variant designed for younger children, with an even stronger story telling bent.
• Blockly is an open-source web-based, graphical language where users can drag blocks together to build an application; no typing is required. It is developed by Google. More information is available at the project home page.
• CiMPLE is a visual language for programming robotic kit for children. It is built atop C as a DSL. ThinkLabs, an Indian Robotics education based startup has built it for iPitara Robotic kit. The language bears strong resemblance to the C language. Approximately 5000+ students in India have bought the iPitara kit and programmed it using CiMPLE. More information is at CiMPLE Original Developers Weblog and ThinkLabs.
• Physical Etoys is a free open-source extension of Etoys. Its philosophy is "help kids model and program the real world in order to learn more about it". It can run on Windows, Linux and Sugar. Physical Etoys lets different electronic devices such as Lego NXT, Arduino boards, Sphero, Kinect, Wiimote joystick, among others, interact between themselves due to its block scripting system.
• Hackety Hack is a free Ruby-based environment aiming to make learning programming easy for beginners, especially teenagers.

While Karel is its own language, Karel++ is a version of Karel implemented in C++, while Karel J. Robot is a version of Karel implemented in Java.
• Kodu is a language that is simple and entirely icon based. It was incubated out of Microsoft Research as a project to reach younger children, and especially girls, into enjoying technology. Programs are composed of pages, which are divided into rules, which are further divided into conditions and actions. Conditions are evaluated simultaneously. The Kodu language is designed specifically for game development and provides specialized primitives derived from gaming scenarios. Programs are expressed in physical terms, using concepts like vision, hearing, and time to control character behavior. The Kodu tool is available in three forms: PC as a free download in public beta and academic forms, and as a low-cost Xbox 360 Live download.
• Logo is an educational language for children, designed in 1967 by Daniel G. Bobrow, Wally Feurzeig, Seymour Papert and Cynthia Solomon. Today the language is remembered mainly for its use of "turtle graphics", in which commands for movement and drawing produced line graphics either on screen or with a small robot called a "turtle". The language was originally conceived to teach concepts of programming related to Lisp and only later to enable what Papert called "body-syntonic reasoning" where students could understand (and predict and reason about) the turtle's motion by imagining what they would do if they were the turtle.
• Lego Mindstorms is a line of Lego sets combining programmable bricks with electric motors, sensors, Lego bricks, and Lego Technic pieces (such as gears, axles, and beams). Mindstorms originated from the programmable sensor blocks used in the line of educational toys. The first retail version of Lego Mindstorms was released in 1998 and marketed commercially as the Robotics Invention System (RIS). The current version was released in 2006 as Lego Mindstorms NXT. A wide range of programming languages is used for the mindstorms from Logo to BASIC to derivatives of Java, Smalltalk and C. The Mindstorm approach to programming now have dedicated physical sites called Computer Clubhouses.
• Mama is an educational object oriented language designed to help young students start programming by providing all the language elements in the student mother tongue. Mama language is available in several languages, with both LTR and RTL language direction support. A new variant of Mama was built atop Carnegie Mellon's Alice development environment, supporting scripting of the 3D stage objects. This new variant of Mama was designed to help young students start programming by building 3D animations and games. A document on educational programming principles explains Mama's design considerations.
• RoboMind is a simple educational programming environment that lets beginners program a robot. It introduces popular programming techniques and also some robotics and artificial intelligence. The robot can be programmed in Arabic, Chinese, Dutch, German, English and Swedish.
• Scratch is a blocks-based graphical language to create animated stories and games.
• Snap! is a free open-source blocks-based graphical language implemented in JavaScript and originally derived MIT's Scratch. Snap! adds the ability to create new blocks and has first-class functions that enables the use of anonymous functions. It is actively maintained by UC Berkeley. The source is entirely hosted on GitHub.
• Stagecast Creator is a visual programming system based on programming by demonstration. Users demonstrate to the system what to do by moving icons on the screen, and it generates rules for the objects (characters). Users can create two-dimensional simulations that model a concept, multi-level games, interactive stories, etc.
• Stencyl is a visual programming and game development IDE that has been used for education and commerce. The concept it uses of code blocks is based on MIT's Scratch visual language (listed above). It also permits the use of normal typed code (separate or intermingled) through its own API and the Haxe language.
• ToonTalk is a language and environment that looks like a video game. Computational abstractions are mapped to concrete analogs such robots, houses, trucks, birds, nests, and boxes. It supports big integers and exact rational numbers. It is based upon concurrent constraint programming.

University

• Curry is a teaching language designed to amalgamate the most important declarative programming paradigms, namely functional programming (nested expressions, higher-order functions, lazy evaluation) and logic programming (logical variables, partial data structures, built-in search). It also integrates the two most import operational principles developed in the area of integrated functional logic languages: "residuation" and "narrowing".
• Flowgorithm is a graphical authoring tool for writing and executing programs via flowcharts. The approach is designed to emphasize the algorithm rather than the syntax of a given language. The flowchart can be converted to several major languages such as C#, Java, Visual Basic .NET and Python.
• M2001 is a modular mathematical language for developing and presenting mathematical algorithms, from modern discrete to classical continuous mathematics. It is built on a semantic framework based in category theory, with a syntax similar to that of Pascal or Modula-2. It is designed for education only, so efficiency and ease of implementation are far less vital in its development than generality and range of application. It was created to play a strong role in forming a formal algorithmic foundation for first-year college math students.
• Oz is a language designed to teach computer theory. It supports most major paradigms in one language so that students can learn paradigms without having to learn multiple syntaxes. Oz contains in a simple and well-factored way, most of the concepts of the major programming paradigms, including logic, functional (both lazy and eager), imperative, object-oriented, constraint, distributed, and concurrent programming. It has a canonical textbook Concepts, Techniques, and Models of Computer Programming and a freely available standard implementation, the Mozart Programming System.
