An Investigation Into Student Reactions Towards Rad Versus Traditional Programming Environments For Novice Developers, Pansy Colkers Jan 2009

An Investigation Into Student Reactions Towards Rad Versus Traditional Programming Environments For Novice Developers, Pansy Colkers

Theses : Honours

The traditional approach to programming using text editors is widely used in many institutions to teach introductory programming. These types of traditional programming environments provide fundamental programming concepts for learning, especially in the context of novice developers. In recent years, teaching institutions have seen a trend towards the introduction of visual "drag-and-drop" rapid application development (RAD) environments for teaching novice programmers. These 'environments capture student interest in programming by allowing the construction of workable programs within a short time frame based on minimal pre-existing coding knowledge. However, some have argued that these visual RAD environments might not be suitable for …


The Design Of 3d Cyberspace As User Interface: Advantages And Limitations, Maria Borisovna Quick Jan 2001

The Design Of 3d Cyberspace As User Interface: Advantages And Limitations, Maria Borisovna Quick

Theses : Honours

Virtual reality propagandists, technologists and the Internet community have long debated the issue of the usability of online three-dimensional (3D) environments. A lot of work was published about the benefits of 3D spaces for human-computer interaction and information visualisation due to their realism (Anders, Kalawsky, Crossley, Davies, McGrath, Rejman-Greene, 1998, Hamit, 1993, Heim, 1992, Aukstakalnis, Blatner, Roth, 1992). This topic also receives continuous industry support including standardisation of Virtual Reality Modeling Language ( VRML, VRML Consortium, 1997) and the more recent Macromedia & Intel alliance "to bring web 3D to the mainstream" (200 1, Intel Corporation). The actual implementation …


An Ada-Like Language To Facilitate Reliable Coding Of Low Cost Embedded Systems, Michael Collins Jan 1995

An Ada-Like Language To Facilitate Reliable Coding Of Low Cost Embedded Systems, Michael Collins

Theses : Honours

Due to a lack of operating system (0/S) support, it is more difficult to develop programs for embedded systems than for workstations. For those developing on a low budget, the problem is often further compounded by the necessity of using inappropriate, 0/S dependent, compilers. This study attempts to ascertain those elements of a High Level Language (HLL) which are absolutely necessary and implementable to produce reliable, efficient, embedded programs without the benefit of a large budget. The study is based upon the Ada philosophy as the Ada language incorporates many desirable features for modelling real-world problems in terms of embedded …


Implementation And Evaluation Of Enhanced Areal Interpolation Using Mapinfo And Mapbasic, Gordon Wragg Jan 1995

Implementation And Evaluation Of Enhanced Areal Interpolation Using Mapinfo And Mapbasic, Gordon Wragg

Theses : Honours

Many researchers today have a need to analyse data in a spatial context. An inherent problem is the mismatch of boundaries between the geographic regions for which data is collected and those regions for which the data is required. Often the solution is to interpolate data from one set of regions to another. This project examines and implements a method of areal interpolation that enables the user to use extra information in areal interpolation to increase the "intelligence ' of the process. This method of Enhanced Areal Interpolation uses a conditional Poisson distribution and the EM algorithm to provide estimated …
