  1. 1. TECH4101: Instructional Design for the Web [Document #9] Instructional design for the Web Dr. Alaa Sadik, Sultan Qaboos University alaasadik@squ.edu.om According to Gagne et al. (1988), the purpose of instructional design is to structure an environment to provide learners with conditions that support learning. Gustafson and Branch (1997) indicated that the main role of instructional design models is to provide conceptual and communication tools to visualise and direct processes for generating guided learning. With the growing development in Web-based education, the need to look for an appropriate design strategy (or model) is highlighted. The review of the instructional design literature shows that design, development and evaluation stages are the main elements included in instructional design models. Spector et al. (1992), for example, suggested a useful model of instructional systems design for analysing the relationship between learner characteristics, the learning environment and the resulting quality of computer-based instruction. They described the model as a ‘cognitively oriented method for developing a useful and predictive process for designing CBI’ (Spector et al., 1992, p. 45). However, although this model is beneficial as a series of stages, Spector et al. did not indicate how to follow or implement this model. In addition, the design depends mainly on the results of behavioural and objectivist research, which has been challenged recently by the constructivist approach. More recently, Kemp et al. (1994) argued that the elements of instructional design process can be represented by answers to four questions: 1. For whom is the programme being developed? 2. What do you want the learners to learn? 3. How is the subject content or skill best learned? 4. How do you determine the extent to which the learning has been achieved? (Kemp et al., 1994, p. 8). 1

Maintenance • Revise content materials. • Revise test items. • Assess course effectiveness. Understanding the requirements of distance education and the capabilities of the Web is important for designing and developing relevant Web-based instruction. For example, designing for the Web requires transforming the Web from a passive publishing tool to an active learning environment to deliver instruction and support distance students. In addition, interaction between instructors and learners and among learners themselves, which is a serious limitation of many distance education environments, should be considered in designing a Web-based instruction environment. Making the learning experience interactive requires adapting and exploiting hypermedia features, involving the communicative approach and providing immediate feedback. However, it is should be mentioned that producing a learning environment for delivery via the Web is different from publishing an information system using traditional types of media. Web-based learning environments have their own nature, components, structure and evaluation strategies. Therefore, developing for the Web requires going through many additional tasks and sub-tasks in the instructional design process. 2

  4. 4. TECH4101: Instructional Design for the Web [Document #9] * Learner analysis The first step in the design and development phase is to understand students’ needs, have information about their educational and cultural background and determine why they need to study at a distance. In the ID models, this stage is an on-going process rather than an introductory stage. Designers can collect information from learners about their feelings, what they prefer and what can be done to make the programme more interesting and helpful. In the present study, information about learners was needed to design the learning environment, choose types of learning, plan for learning activities and anticipate the degree to which students would need technical and educational support. ** Front-end analysis Front-end analysis is the second step in designing any programme. It is the designer’s role to investigate the needs of the programme to see whether they are met by an already established learning environment or not and to evaluate the limitations of other alternatives and the outcomes of developing a new programme. The evaluation approach is mainly based on the review of the literature and conducted in the light of the following issues: 1. Limitations of previous distance education systems and the framework for describing the features of distance education technologies (type of interaction, type of learning, costs, ease of use, flexibility, etc.); 2. Bates’ (1995) ACTIONS model for evaluating and comparing among distance education technologies; 3. Types and requirements of developing and receiving on-line learning and delivery of media via the Web. 4. Models of using the Web in education, theories and types of on-line learning and the framework of features and elements of on-line learning (tutorial, interaction, management and support). 4
