OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.

First steps are to gain an understanding of the intended user and task objectives by collecting initial requirements during requirements determination.  Requirements determination: Who will use the form or report? What is the purpose of the form or report? When is the report needed or used? Where does the form or report need to be delivered and used? How many people need to use or view the form or report?  Prototyping Initial prototype is designed from requirements. Users review prototype design and either accept the design or request changes. If changes are requested, the construction-evaluation-refinement cycle is repeated until the design is accepted.  A coding sheet is an “old” tool for designing forms and reports, usually associated with text-based forms and reports for mainframe applications.  Visual Basic and other development tools provide computer-aided GUI form and report generation. Deliverables and Outcomes  Design specifications are the major deliverables and inputs to the system implementation phase.  Design specifications have three sections:  Narrative overview: characterizes users, tasks, system, and environmental factors  Sample design: image of the form (from coding sheet or form building development tool)  Testing and usability assessment: measuring test/usability results (consistency, sufficiency, accuracy, etc.) Formatting Forms and Reports find more resources at find more resources at  Meaningful titles — use clear, specific, version information, and current date  Meaningful information — include only necessary information, with no need to modify  Balanced layout — use adequate spacing, margins, and clear labels  Easy navigation system — show how to move forward and backward, and where you are currently Highlighting information  Notify users of errors in data entry or processing.  Provide warnings regarding possible problems.  Draw attention to keywords, commands, high-priority messages, unusual data values. Color vs. No Color  Benefits — Color: Soothes or strikes the eye. Accents an uninteresting display. Facilitates subtle discriminations in complex displays. Emphasizes the logical organization of information. Draws attention to warnings. Evokes more emotional reactions.  Problems from Using Color Color pairings may wash out or cause problems for some users. Resolution may degrade with different displays. Color fidelity may degrade on different displays. Printing or conversion to other media may not easily translate. Displaying Text  Case: display in mixed upper and lower case, use conventional punctuation  Spacing: use double spacing if possible, otherwise blank lines between paragraphs  Justification: left justify text, ragged right margins  Hyp
