  1. Effect of instruction types and task assignments

  2. Overview Asynchronous Synchronous Local Autologging User Reporting Remote

  3. Instructions • Three types of instruction: • Definition • Examples • Definition + Examples • Definition: • Usability problems are present when the system is: • Unuseful: You cannot find the documents or functions you need to solve your tasks. • Difficult to learn: It takes a long time to learn how to use the system. • Difficult to remember: It takes a long time to find elements in the system, which you have used previously. • Ineffective to use: It takes a long time to solve certain tasks with the system. • Unsatisfying to use: The system does not feel comfortable to use, it is not joyful to work with it.

  4. Instructions • Three types of instruction: • Definition • Examples • Definition + Examples • Example of a usability problem: • I wanted to insert a footnote in my document. I expected to find this function under the menu called 'Insert', but I could not find it. I also tried to look in the menus 'Page layout' and 'View', but without any luck. It was somewhat irritating. I tried to solve the problem by using the help function and found that I must select the 'Reference' menu, which provided me with the correct functionality. It was not intuitive that something I want to insert is located within the 'Reference' menu and not within the 'Insert' menu.

  5. Task types • Predefined tasks • Example: Imagine that you failed an exam for the third time. Find out what you must do to get a fourth try. • No tasks • Users were asked to solve tasks relevant for their daily work.

  6. Experimental Setup Remote asynchronous 53 ICT students (Computer Science, Informatics, Software Engineering etc.) Evaluation of a website for students (sict.aau.dk)

  7. Experimental Setup

  8. Effect of instruction types No. of problems found Subjective ratings (1 = lowest satisfaction, 5 = highest satisfaction)

  9. Effect of task types • No. of problems found • No tasks = 2.16 (average) • Tasks = 6.67 (average) • No. of tasks solved No tasks = 1.5 (average) Tasks = 3.7 (average)

  10. Effect of task types Total number of problems found Problem Agreement

  11. Konklusion • Users receiving examples: • Identified more problems • Gave higher satisfaction ratings • Users receiving predefined tasks: • Solves more tasks • Identify more problems • Have a higher problem agreement • Users that don’t receive predefined tasks identify a more varied set of problems

  12. Fremtidig forskning: Remote evaluering i praksis Andre brugertyper Anvendelse i virksomhed Direkte integration i software

  13. Efter pausen • Individuelle spørgeskema udfyldt
