This method does not disregard or minimize the syntax or required logical constructs. The stude nt can con centrate more on the logic and less on the language itself. Key Words: Graphical Programming, Introductory Programming, String Search Application European Journal of Business and Social Sciences, Vol. 767X EUROPEAN JOURNAL OF BUSINESS AND SOCIAL SCIENCES 179 The MIT App Inventor [1] devel opment system is Java based and incorporates a web browser and for this paper, an Android phone emulator. The student stores his/her work on the App Inventor servers. Programming occurs in two phases. In the Designer screen, the student selects and inserts components such as buttons, textboxes, and labels. The Blocks Editor provides lists of colored blocks that interact with each other depending upon the function. Blocks for logic,control, and variable s are assembled to provide the program code . From a te aching and learning standpoint, t he syntax issue is essentially taken out of the development. When incompatible blocks are joine d to together, the action is bl o c ked with an error pop - up. The logic, analysis and arrangement of procedures still remain the s tudent’s perogative. Visual Programming In addition to the App Inventor software, there are a number of software packages that can be classi fied as visual programming languages. We list three other examples which are free downloads. Program ming Without Coding Technology [2] is a software package that provides a GUI, which allows the student to construct a program by using a n interface with pop - up boxes and templates to reduce the need to know the exact syntax. PWCT is a free download. The stude nt is still required to have a logical overview of the code. For the problem presented in this paper, the string functions provided were sufficient. The GUI provides a structured way to control the levels of code such as code inserted within a While - L oop o r an If - Then statement. Microsoft VPL [4] is a graphical programming package that is part of the Microsoft Robotics Developer Studio . This application is used to guide and operate robots. The approach of software uses a graphical dataflow - based programming model, where the components initiate action once all the signals or messages arrive rather than a sequence of commands executed in sequence. The language purportedly targets the beginning programmer. The following picture shows the code to increment a variable by one until it reaches a maximum of ten.
