            everyone who is a stakeholder needs to be represented in a design team, but the
            effect of the product on them must be taken into consideration (Preece et al., 2002).

              After the stakeholders have been identified, a thorough investigation of their
            needs should be conducted by doing tasks and needs analyses (Clark & Estes,
            1996). Then, designers can develop alternative design solutions to be evaluated by
            the actual users. In both the design process and evaluation process, users should be
            involved in. Ways to involve users in the design, development, and evaluation of a
            product were shown in Table 5.1 (Preece et al., 2002).



            5.4  Learner-Centered Design

            Comparing with UCD, learner-centered design (LCD) emphasizes the importance
            of supporting students’ growth and their motivational needs in designing educa-
            tional software. Learner-centered indicates a move from ease-of-use issues toward
            the development of a student’s comprehension and expertise. Table 5.2 shows the
            difference between users and learners.

            • Users have the expertise in their work domains, and they understand the tasks
              they are accomplishing. Learners do not have the same domain knowledge as
