Understand the high school students by directly studying their cognitive, behavioural, anthropomorphic, andattitudinal characteristics. In this case we know that our users are going to be high school students.The syllabus and outcomes have to be studied, and subject matter experts consulted, and it should bedetermined how technology can be used to improve the learning experience.This requires observinghigher school students doing their normal tasks, studying the nature of those tasks, and theninvolving the students in the design process.(explaining the main principle, 3 marks)Students are expected to expand on the above to discuss the design of mobile phone e-learning site under thefollowing sub principles (5 marks).User tasks and goals are the driving force behind the development - Technology should not bethe driving forceUser’s behavior and context of use are studied and the system is designed to support them.User’s characteristics are captured and designed for.Users are consulted throughout the development from the earliest phases to the latest and theirinput is seriously taken into account.All design decisions are taken within the context of the users, their work, and their environment.Empirical measurement (6 marks)(Students are expected to contextualize this to the design of a mobilephone e-learning site. Without contextualizing students lose marks)At the beginning of the project, identify and document the targeted usability and user experience goals. Thisenables the mobile phone e-learning site to be empirically evaluated at regular stages as it is developed. Theinsights gathered from these measurements can guide the designers to choose between alternative designs.Iterative design(6 marks)(Students are expected to contextualize this to the design of a mobile phone e-learning site. Without contextualizing students lose marks)Feedback is essential to the iterative design process. Iteration is required because designers never get thesolution right the first time.
INF37208When problems are found in user testing, they are fixed and then more tests and observations are carried outto see the effects of the fixes. This means that design and development is iterative, with cycles of design-test-measure-redesign being repeated as often as necessary.Question 4[20 marks]Compare usability testing (UT) and field studies (FS) under the following headings:4.1 The environment in which the evaluation is conducted(4 marks).4.2 The participants(2 marks)4.3 Data collection(6 marks).4.4 Advantages and disadvantages(8 marks) ( (2 marks for disadvantages and 2 marks for advantages percategory) x 2 = 8 marks).Answer4.1The environment in which the evaluation is conductedField Studies are conducted in the natural environment where the system or product isused. For example, at a company where the product would be used.Usability testing is conducted in a laboratory where the conditions are controlled during theexperiment. For example, a usability laboratory.4.2The participants.
