This project was developed to address the complex issue of disseminating information to high school students via the World Wide Web. Topics include: the need for greater communication among instructors, students and parents, the need to utilize instructional design techniques, the backwards design process in the development of web based projects; and the need to integrate internet technology for promoting instruction and learning.

The purpose of this thesis was to create an Online Mentoring website that would benefit teachers by helping them to feel more confident and efficient through their first couple of years teaching. Its focus is to provide new teachers access to all information involving its processes, procedures and expectations within a specific school site.

The main purpose of this project is to provide an easy-to-use interface for students and faculty members to interact with each other during the course of a student's internship class.

The purpose of this project is to provide students and teachers with a disk of tools to aide in the development of Web pages either in the classroom or through online (distance education) learning. Many of the tools supplied on this disk have been field tested in a high school Web design class. When students are allowed to be creative and are able to fuse interesting visual displays the results can be significant in increasing cognitive and multiple intelligences skills.

The development of the Internet as a means of offering services (information sources), are developing means for presenting services to users online. Service is called everything that gives users the opportunity to educate, entertain the possibility of trade and of course meet new people. Means are programming languages and programming environments. The project aims to use these resources and create a website that would serve as an electronic support in the subject Elektronic Deutsch. Content sites is also information relating to the German language as well as test. Test is to assess the student's options for the successful completion of the course in Elektronic Deutsch.

Title of dissertation: Web Audit Methodology A web site is often the first point of contact between the user and another person or company or organization, so that in the electronic world, a web site is like a calling card. Ideally therefore, a web site should load relatively quickly to prevent the user from looking elsewhere even before the web site has opened. Also, the web site should have a pleasant design to make it user-friendly, it should display helpful content, be widely accessible and, last but not least, fulfil the aims for which it was created. It is the responsibility of web site designers, programmers and creators to ensure that web sites fulfil their function. A web site audit - either during or after its construction - is the best way of checking that all factors relating to access, use, technical processes and other criteria function correctly. There are many audit companies on the market today, each of them offering the customer its own particular perspective, evaluation according to different criteria and audit conducted using various methods. Therefore, the first part of this work contains an overview of different perspectives used to assess the quality of web sites, as well as designers and the specific methodology they apply during web site audits. The second part of this work...

Indiana University-Purdue University Indianapolis (IUPUI) / With the continuous growth of health information on the Internet, providing user-orientated health service online has become a great challenge to health providers. Understanding the information needs of the users is the first step to providing tailored health service. The purpose of this study is to examine the navigation behavior of different user groups by extracting their search terms and to make some suggestions to reconstruct a website for more customized Web service. This study analyzed five months’ of daily access weblog files from one local health provider’s website, discovered the most popular general topics and health related topics, and compared the information search strategies for both patient/consumer and doctor groups. Our findings show that users are not searching health information as much as was thought. The top two health topics which patients are concerned about are children’s health and occupational health. Another topic that both user groups are interested in is medical records. Also, patients and doctors have different search strategies when looking for information on this website. Patients get back to the previous page more often, while doctors usually go to the final page directly and then leave the page without coming back. As a result, some suggestions to redesign and improve the website are discussed; a more intuitive portal and more customized links for both user groups are suggested.

Indiana University-Purdue University Indianapolis (IUPUI) / The web applications are now being used in many security oriented areas, including online shopping, e-commerce, which require the users to transmit sensitive information on the Internet. Therefore, to successfully authenticate each party of web applications is very important. A popular deployed technique for web authentication is the Hypertext Transfer Protocol Secure (HTTPS) protocol. However the protocol does not protect the careless users who connect to fraudulent websites from being trapped into tricks. For example, in a phishing attack, a web user who connects to an attacker may provide password to the attacker, who can use it afterwards to log in the target website and get the victim’s credentials. To prevent phishing attacks, the Two-Way Password Protocol (TPP) and Dynamic Two-Way Password Protocol (DTPP) are developed. However there still exist potential security threats in those protocols. For example, an attacker who makes a fake website may obtain the hash of users’ passwords, and use that information to arrange offline password guessing attacks. Based on TPP, we incorporated challenge responses with arbitrary images to prevent the off-line password guessing attacks in our new protocol, TPP with Challenge response using Arbitrary image (TPPCA). Besides TPPCA, we developed another scheme called Rain to solve the same problem by dividing shared secrets into several rounds of negotiations. We discussed various aspects of our protocols, the implementation and experimental results.
