There are the approches used to create an evaluation paradigms,
Quick and dirty evaluation
Heuristic evaluation
Usability testing
Observing users
Only experts will be evaluate using this approach
Quick and dirty evaluation
Usability testing
Field studies
Predictive evaluation
This evaluation gives in early of design to check users' needs are asssess to the problems or met with the design opportunity
Quick and dirty evaluation
Usability testing
Field studies
Predictive evaluation
The evaluation must produce with the product design or prototype to be evaluate by the user

Predictive evalaution
Conceptual model based on activity includes,
Usability testing
Instructing
Conversing
Predictive evaluation
Direct manipulation has THREE (3) fundamental properties, EXCEPT
continuous representation of the objects and actions of interest
rapid reversible incremental actions with immediate feedback about the object of interest
infrequent users can remember how to carry out operations over time
physical actions and button pressing instead of issuing commands with complex syntax
There are the evaluation techniques used for evaluation concept,
observing users
asking experts their opinions
predictive evalaution
field studies
Testing typical users on typical tasks in a controlled laboratory
Observing user
Asking user their opinions
Asking experts their opinions
User testing
Model are used to predict the efficiancy of an interface or compare performance time between versions
Observing users
User testing
Asking experts
Modelling users' task performance
The system should always keep users informed about what is going on through appropriate feedback in reasonable time.
Visibility of system status
Consistency and standards
Error prevention
Help users recognize, diagnose, and recover from errors
The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system oriented terms.
Aesthetics and minimalist design
Visibility of system status
Match between system and the real world
Help and documentation
Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.
Match between system and the real world
Consistency and standards
Help and documentation
User control and freedom
Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.
Consistency and standards
Match between system and the real world
Help users recognize, diagnose, and recover from errors
Help and documentation
Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.
Recognition rather than recall
Flexibility and efficiency of use
Aesthetics and minimalist design
Error prevention
Minimize the user's memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.
Visibility of system status
Match between system and the real world
Recognition rather than recall
Error prevention
Accelerators -- unseen by the novice user -- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.
Help users recognize, diagnose, and recover from errors
Flexibility and efficiency of use
Recognition rather than recall
Consistency and standards
Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
Aesthetics and minimalist design
Help users recognize, diagnose, and recover from errors.
Help and documentation
Match between system and the real world
Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.
Visibility of system status
User control and freedom
Error prevention
Help users recognize, diagnose, and recover from errors
Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation.

Which of the following is the best indicator that a Web site is reliable?
The author of the site tells you the information is reliable.
The author of the site provides contact information and his or her qualifications.
The author links to his or her favorite Web sites.
The author states in bold letters that the site was proofread by a teacher.
Evaluating content on the Web is important because:
Web authors are always less professional.
Web authors are always biased.
Anyone can publish on the Web. There is no guarantee that what you’re reading is reliable.
Printed information is always more accurate than information found on the Web.
When you are testing to find out if the website you are using has the most up to date information, you are testing for:
Purpose
Authority
Currency
Relevancy
Evaluation is an optional task
True
False
