Which strategy would be best for a class with 60% of learners reporting the preferred learning style as visual? — Divide the class into groups and have each create a concept map linking concepts from the reading – Linking the concepts together would allow the learner to visualize the connections.
Usability studies can be used to support IT in a number of ways. Which of the following are reasons to complete these studies in a health care setting? –assesses the adequacy of a design or redesign early in the systems life cycle, helps determine or clarify users’ requirements determination
Usability: the ease with which people can use an interface to achieve a particular goal. issue of human performance during computer interactions for specific tasks within a particular context. which deals with specific issues of human performance during computer interactions for specific tasks within a particular context. usability issues address the efficiency and effectiveness of an application. For example:
- the ease of learning an application
- the ease of using an application
- satisfaction with using
- efficiency of use
- error tolerance
- fit of the system to the task
- the speed of task completion and errors that occurred during application use when determining which system or application would be best used on a nursing unit.
- Heuristic Evaluation = discount usability evaluation method: to detect problems early in the design process, when they can be most easily and economically corrected.
- Formal usability test: use either experimental or observational studies of actual users using the interface to accomplish real-world tasks.
Ergonomics: the design and implementation of equipment, tools, and machines related to human safety, comfort, and convenience. commonly refers to attributes of physical equipment or to principles of arrangement of equipment in the work environment.
When displaying patient data for clinical decision making, which type of display tends to slow cognitive processing of the data? — multiple displays on one screen (distracting and slow cognitive processing of data. in most cases, multiple modes of presentation of data provide the best information)
The effective display or patient data for clinical decision making requires that information be rapidly available with minimal cognitive effort. The decision tree is a common presentation with potential options, consequences, and expected outcomes.
Graphs: line graphs, column graphs, and bar charts (compare variables), pie charts and area charts (illustrate the percentage composition of an entity)
Line graph: used to show data over a period of time. is considered the best type of chart for displaying data over time.
Table: use labeled columns and rows to present statistical or alphabetical data in an organized way. although technically not visual aids, they provide a different way of grouping and presenting analyzed data that an analyst wants to communicate to proposal readers.
Pictorial displays: visual indicators, such as colors, may be used to highlight information, such as abnormal lab results, and pictorial displays can be effective.
