Term Paper: Students’ Self-Service Website for Mobile Devices

Developing a mobile web application for student self-service at Strayer University involves several critical phases, including information gathering, design strategy, prototyping, implementation, and maintenance. The goal is to create an intuitive, accessible, and efficient platform that allows students to access personal and academic information seamlessly across various mobile devices such as iPhone, iPad, Android phones, and Blackberries. This paper outlines a comprehensive human-computer interaction (HCI) approach to achieve this objective.

Information Gathering

The purpose of the mobile self-service platform is to provide students with easy, on-the-go access to essential academic and personal information. Its primary goals include enabling students to enroll in courses, view schedules, check grades, and update personal details without the constraints of desktop computers. The target audience encompasses currently enrolled students at Strayer University, ranging from undergraduate to graduate levels, and includes individuals with diverse technological skills and access to various mobile devices.

Understanding the needs and wants of this audience involves recognizing their desire for quick, reliable, and secure access to their information. Students prefer interfaces that are simple, fast-loading, and easy to navigate on small screens, with minimal steps required to complete tasks. They value features such as push notifications for updates, clear visual hierarchies, and responsive layouts that adapt to different screen sizes to enhance usability.

Resources necessary to develop this mobile web application include technical infrastructure such as servers and hosting platforms, development tools like wireframing software and coding frameworks, human resources including UI/UX designers, developers, and testers, and ongoing support staff to maintain the system. Additionally, feedback mechanisms need to be established to continuously gather user input and adapt the platform to evolving needs.

Design Strategy

Mobile Website Design

The design of the mobile website must prioritize simplicity, responsiveness, and accessibility. Utilizing a mobile-first approach ensures the interface adapts smoothly to various device sizes and operating systems. Key design principles include clear visual hierarchies, minimalistic layout, and touch-friendly controls such as larger buttons and easily navigable menus. Consistency across pages improves user comprehension, while visual cues guide users through tasks efficiently.

Applicable Interfaces

The application should support native mobile interface elements, such as touch gestures, hardware buttons, and onboard sensors. To maximize compatibility, a hybrid approach combining HTML5, CSS3, and JavaScript frameworks like React Native or Vue.js can be employed. These allow for responsive interfaces and dynamic content updates, delivering a native-app-like experience within a web browser. Features such as biometric authentication, geolocation, and camera integration can enhance functionality if supported by the device.

Wireframe Designs

Wireframes created through tools like Microsoft Visio or open-source alternatives (e.g., Pencil, Wireframer) depict the user interface. The home page design includes a clean, straightforward layout with quick access icons to key functions like enrollment, grades, and personal information. The course enrollment page features a simple form with dropdowns, checkboxes, and submit buttons, optimized for mobile use with appropriately sized touch targets and minimal text.

Prototyping

Prototypes serve as interactive mockups that simulate the user experience before full development. They can range from low-fidelity sketches to high-fidelity, clickable models. For Strayer University’s self-service site, developing both prototypes allows stakeholders to visualize functionality and flow, gather feedback, and make iterative improvements.

The usability testing methods suitable include formative testing with real users performing common tasks, heuristic evaluations to identify interface flaws, and A/B testing comparing different design options. User testing sessions should focus on ease of navigation, task success rate, and satisfaction. Data collected through session recordings, surveys, and heatmaps inform refinements aimed at optimizing the user experience.

Evaluation methods encompass quantitative metrics such as task completion time and error rates, as well as qualitative feedback on perceived usability and aesthetics. This comprehensive approach ensures the final design aligns with user preferences and operational goals.

Implementation

The implementation phase involves deploying the mobile self-service application across various devices by leveraging responsive web design (RWD) techniques. This includes adapting HTML/CSS code to ensure layouts fluidly resize and reorganize elements based on screen dimensions. Using progressive enhancement ensures that the core functionality remains accessible even on older or less capable devices.

Cross-platform development frameworks like React Native or Flutter can facilitate a unified codebase that runs efficiently on iOS, Android, BlackBerry, and other platforms. For security and compliance, the implementation must integrate with university authentication systems, employ SSL/TLS encryption, and adhere to data privacy standards. Testing across multiple devices and operating systems is crucial to identify and correct device-specific issues before launch.

Maintenance and Growth

Maintaining the relevance and functionality of the mobile self-service site requires establishing clear guidelines for regular updates and upgrades. As new mobile devices and operating system versions are released, continuous compatibility testing is necessary. A dedicated team should monitor technological trends and update the platform accordingly, ensuring support for new screen sizes, hardware capabilities, and security protocols.

Implementing an agile development approach with iterative releases enables quick adaptation to technological advances. Incorporating user feedback mechanisms like surveys or in-app reports helps identify usability challenges and prioritize updates. Additionally, keeping documentation, source code, and development standards current facilitates smooth onboarding of new developers or support staff to sustain ongoing growth.

Partnerships with device manufacturers and leveraging industry standards for mobile web compatibility will enhance long-term maintainability and scalability of the self-service platform.
