A model for information architecture of government web sites in Southern Africa

Bernardo, Tomás January 2006 (has links)
The main purpose of this research is to investigate the Information Architecture (IA) of government web sites in Southern Africa. The government web sites of Mozambique and South Africa were selected for the purpose of this research. A further aim of this research was to derive a model for the IA of government web sites. The model was based on IA components and guidelines as well as on web site components and E-government requirements. The IA guidelines in the model were derived from general design guidelines and guidelines for government web sites. The IA guidelines in the proposed model were used to conduct an analytical and empirical evaluation of the selected sites. The selection of the sites was based on similarities in the Information and Communication Technology (ICT) strategies and policies, the annual Internet growth rates, the Internet user profiles and the Egovernment initiatives in both countries. Differences between the sites also contributed to their selection. Mozambique is one of the least developed countries in the world, while South Africa is one of the most developed countries in Africa. Heuristic evaluation was used for the analytical evaluation while questionnaires and user testing were used for the empirical evaluation. Some of the usability problems identified in the heuristic evaluation, such as incorrect organisation of information and navigation issues, were also identified in the empirical evaluation, confirming to the existence of these usability problems. The results of this research show that the IA of government web sites has an impact on user performance and satisfaction and that the proposed model can be used to design and evaluate the IA of government web sites in Southern Africa.

An investigation into the use of guidelines and patterns in the interaction design process

Cowley, Niel Lester Orr January 2009 (has links)
Design guidelines are used in interaction design (IxD) for physical design and for evaluating the usability of designs and interactive products. Guidelines are widely used for physical design and evaluation, but have a number of problems. IxD patterns have been proposed as an alternative to guidelines, as they are claimed to have several advantages over guidelines. A small number of empirical studies provide evidence that patterns are beneficial when used in IxD. Additional research on the usefulness of IxD patterns is required. The primary research question investigated in this thesis was thus: How useful are IxD patterns as physical design and evaluation aids in IxD, as compared to design guidelines? The role of guidelines and patterns as design and evaluation aids in IxD was investigated and a comparison of guidelines and patterns, based on a set of guideline and pattern properties, was conducted. The concept of pattern and guideline usefulness was explored and a research agenda for guidelines and patterns was identified, together with a set of research questions for an empirical study. The empirical study of the use of patterns for evaluation, redesign and new design, as compared to guidelines, was conducted at the Nelson Mandela Metropolitan University in 2004. The participants were a purposive sample of post-graduate Computing students, who were regarded as novice interaction designers. Two equivalent groups were formed, one that used patterns and one that used guidelines. Patterns were found to be as useful as guidelines when used as evaluation aids. Guidelines and patterns were identified as effective tools for identifying and explaining usability issues and design features. Best-effort matched sets of guidelines and patterns produced substantially different result sets when used to identify issues and features, with fairly low overlap. A substantial evaluator effect was observed for the use of guidelines and patterns for evaluation, and the results obtained were similar to those obtained by Molich et al. in their Comparative Usability Evaluation (CUE) studies. There was no statistically significant difference between the effectiveness of guidelines and patterns for evaluation. There was also no statistically significant difference between the perceived efficiency, effectiveness and satisfaction in use of guidelines and patterns for evaluation. Guidelines and patterns were found to be used in similar ways for evaluation. Patterns were found to be more effective than guidelines for redesign. Patterns were found to be as useful as guidelines when used for new design. There was no statistically significant difference between the effectiveness of guidelines and patterns for new design. There was also no statistically significant difference between the perceived efficiency, effectiveness and satisfaction in use of guidelines and patterns for redesign and new design. Guidelines and patterns were found to be used in similar ways for design. There was no statistically significant difference between the perceived usefulness of the format, content, ease of learning, and usefulness as personal and shared design languages, of guidelines and patterns. Both participant groups were equally agreeable to using guidelines and patterns in the future. The perceived usefulness of pattern collections was found to depend on the usability of the collection interface and the content quality of the patterns. The results of the empirical study thus provided empirical evidence that patterns were as useful as guidelines for evaluation and new design, and were perceived as positively as guidelines were. Patterns were found to be superior to guidelines for redesign. Patterns can therefore be used with a measure of confidence as early stage design aids for physical design and evaluation in the future. In addition to these findings, a number of opportunities for further research were identified.

Development of a web-based interface for a wireless sensor network monitoring system

Gumbo, Sibukele January 2007 (has links)
In the recent past, wireless sensor technology has undergone advancements in its autonomous data collecting aspects, and has become an area worth investigating in relation to structural monitoring applications. The system described in this thesis aims at acquiring, storing and displaying overhead transmission line related data collected from a wireless sensor network. Open source tools were used in its development and implementation. The inherent linearly aligned topology of transmission line monitoring devices is not without shortcomings; hence analysis of linear node placement, hardware and software components was carried out to determine the feasibility of the system. Their limited data processing capabilities has motivated the development of a post processing wireless sensor application in order to present any collected structural data in an understandable format.

Student preferences in screen design factors for Internet delivered college courses.

Pineau, Joseph Roy 05 1900 (has links)
Colleges and universities throughout the world are offering many of their courses via the Internet. Some institutions offer entire degrees online. This has ushered in a renewed interest in the debate on the effectiveness of non-traditional course delivery method. Numerous educational research studies have been conducted in an attempt to quantify that effectiveness. In any form of experimental research, control of variables is paramount. The rich multimedia capabilities of the World Wide Web give educators a wide variety of delivery media. However, with the exception of advice from artisans on design factors of the media, little research has been conducted with regard to the aesthetics of Web page design as viewed by the student. This study was conducted in an effort to establish student preferences with regard to two factors of Web page design as they might be used on those Web pages, background color and typeface used for text. In addition, it contains an analysis of whether or not there is an interaction between the two factors. Use of the results of this study should prove beneficial to both educators and educational researchers in their future endeavors.

A comparative analysis of teacher-authored websites in high school honors and advanced placement physics for web-design and NSES content and process standards

Unknown Date (has links)
The purpose of this study was to investigate whether statistically significant differences existed between high school Honors Physics websites and those of Advanced Placement (AP) Physics in terms of web-design, National Science Education Standards (NSES) Physics content, and NSES Science Process standards. The procedure began with the selection of 152 sites comprising two groups with equal sample sizes of 76 for Honors Physics and for Advanced Placement Physics. The websites used in the study were accumulated using the Google[TM] search engine. To find Honors Physics websites, the search words "honors physics high school" were entered as the query into the search engine. To find sites for Advanced Placement Physics, the query, "advanced placement physics high school," was entered into the search engine. The evaluation of each website was performed using an instrument developed by the researcher based on three attributes: Web-design, NSES Physics content, and NSES Science Process standards. A "1" was scored if the website was found to have each attribute, otherwise a "0" was given. This process continued until all 76 websites were evaluated for each of the two types of physics websites, Honors and Advanced Placement. Subsequently the data were processed using Excel functions and the SPSS statistical software program. The mean and standard deviation were computed individually for the three attributes under consideration. Three, 2-tailed, independent samples t tests were performed to compare the two groups of physics websites separately on the basis of Web Design, Physics Content, and Science Process. The results of the study indicated that there was only one statistically significant difference between high school Honors Physics websites and those of AP Physics. / The only difference detected was in terms of National Science Education Standards Physics content. It was found that Advanced Placement Physics websites contained more NSES physics content than Honors Physics websites. There was no significant difference found between the two types of high school physics websites in regards to web-design, and NSES science process standards. It is hoped that the results of this study may serve as a guide for researchers to explore the role of Web-Assisted Instruction (WAI) as an enhancement to traditional instruction in physics. With the first generation to grow up in the digital age now in high school, WAI may prove to be useful as method to improve critical thinking skills and provide opportunities for inquiry beyond the classroom. / by Ronald C.

Development of a usable website for an electric motorboat drag racing physics project

Barry, Reno Don 01 January 2006 (has links)
The project developed a web site for a high school physics projected called "Electric Motorboat Drag Racing." The web site was produced following the ADDIE instructional design model (analyze, design, develop, implement, evaluate) and was designed using key usability concepts identified through research: speed, content, appearance, and navigation (SCAN). The web site was developed and tested by asking experts for their feedback and by having participants use the web site. The web site was implemented in physics classrooms and data from 43 participants were evaluated. The data showed 97 percent of the participants' boats successfully completed the five-meter drag race. It also showed that the two targeted California physics standards were selected most often by participants as the standards they most needed to apply, learn, or review to complete the project. Through testing and evaluation, the web site was made more usable and the project helped physics students learn and apply specific physics concepts while gaining hands-on experience.
