- “ End-user development (EUD) is a research topic within the field of computer science, describing activities or techniques that allow people who are not professional developers to create or modify a software artifact. A typical example of EUD is programming to extend and adapt an existing package (e.g. an office suite). There are two basic reasons why EUD has become popular, one is because organizations are facing delays on projects and using EUD it can effectively cut the time of completion on a project. The second reason is that software tools are more powerful and easier to use.” ([http://en.wikipedia.org/wiki/End-user_development End-user development (Wikipedia), retrieved 09:27, 18 August 2008 (UTC)).
- “ Not all programs are written by professional computer programmers. "End users" with the right tools automate laboratories and corporate data access, model fusion reactors and animate Web pages.” [End user programming] “ covers the tools, techniques, and theory of people who exploit computer automation for their purposes without becoming professional programmers” (End-User Programming, retrieved 13:16, 5 September 2006 (MEST))
- “ There has been considerable work in empowering end users to be able to write their own programs, and as a result, users are indeed doing so. In fact, the number of end-user programmers in the United States is expected to reach 55 million by 2005, as compared to only 2.75 million professional programmers. The "programming" systems used by these end users include spreadsheet systems, web authoring tools, and graphical languages for demonstrating the desired behavior of educational simulations. Using such systems, end users create software, in forms such as educational simulations,” (About EUSES, retrieved 13:16, 5 September 2006 (MEST)). spreadsheets, and dynamic e-business web applications.
End-user programming is very popular in educational technology. Many (or most) authoring environments - in particular multimedia authoring systems do have programming facilities and that are used by end-users. Of course defining"end-user" is not obvious. Clearly, a teacher who develops interactive applications that include some scripting is an end-user. A multimedia designer without proper CS training that does the same rather should be called a "light-weight" programmer. Anyhow, both cases do have in common the idea that many programs are written by none-professional programmers.
Methods and examples
See also computer programming.
- Application-specific Languages
- Programming by Example PBE
- Also known as Programming By Demonstration (PBD), a technique for teaching the computer new behavior by demonstrating actions on concrete examples. The system records user actions and generalizes a program that can be used in new examples)
- E.g. keyboard macros in an editor
- Visual Programming
- A Visual programming language (VPL) is any programming language that lets users specify programs by manipulating program elements graphically rather than by specifying them textually (Wikipedia, retrieved 09:27, 18 August 2008 (UTC)).
- Multimedia authoring systems (e.g. Authorware), microworlds (e.g. AgentSheets or Etoy) and 3D interactive environments (e.g. Alice) often include visual programming languages.
- Natural Programming
- general principles, methods, and programming language and environment designs that will significantly reduce the amount of learning and effort needed to write programs for people who are not professional programmers.
- E.g. programming microworlds
End-user programming in educational technology
In education, there are basically three kinds of technologies used by end-users:
- Standard wide-spread end-user tools (e.g all sorts of scripting languages for the Internet, Macro-languages for professional tools).
- Authoring kits/languages for educational software (in particular interactive multimedia)
- Special-purpose toolkits like microworlds to build highly advanced educational software: “ The demand for educational software is growing exponentially with the surge of interest in educational reform, the Internet, and distance learning. Educational applications must be very flexible because curricula and teaching styles vary tremendously among institutions, locations, and even among instructors at the same institution. To meet these needs, a wide array of small-scale, casual developers at universities, research labs, and small businesses develop educational software, and no dominant solution or supplier has emerged.” (Roschelle et al., 1999).
- Authoring environments for interactive web pages
- E.g. Tools like Dreamweaver
- Interactive multimedia toolkits
Some of these can be run over the Internet (e.g. through special plugins).
Often they are based on some kind of components that authors and teacher authors then can combine and adapt to their needs. E.g. systems like:
Some of these can be run over the Internet (e.g. they compile in Javacode)
