GOALSelection of an appropriate courseware
development platform for e-learning
program using Analytic Network Process.
Which is the best of the different courseware development platforms for a e-learning program?

CONTRIBUTIONSDetermination of main and sub criteria in
courseware development platform selection problem
To suggest a hierarchical approach including tangible and intangible criteria (clusters) to evaluate different courseware development platforms
To indicate applicability of ANP for like this multi criteria decision problem in distance education
METHODOLOGYANALYTIC NETWORK PROCESS
The ANP can be used as an effective tool in those cases where the interactions among the elements of a system form a network structure. This network means the interaction (interdependency) between criteria.
The ANP is a theory of measurement generally applied to the dominance of influence among several alternatives with respect to an attribute or a criterion.
ANP is also applied to evaluate the dominance of criteria with respect to a higher criterion and it is applied to evaluate alternatives with respect to a governing criterion.
The structure of the ANP model is described by clusters
of elements connected by their dependence on one another. A cluster groups elements that share a set of attributes. At least one element in each of these clusters is connected to some element in another cluster. These connections indicate the flow of influence between the elements.

STEPS OF ANPStep 1: Model construction and
problem structuring Step 2: Pair-wise comparisons matrices and
priority vectors
Step 3: Super-matrix formation Step 4: Selection of best alternatives
DEFINITION OF MAIN AND SUB CRITERIA
FINANCIAL: Cost is an important dimension in the selection of the courseware development platform. Start-up CostsOngoing Costs Upgrading Costs
INSTRUCTIONAL: Web-based course management programs let us to track, evaluate and grade student activities. In the instructional main criterion instructor element (sub criterion) forms the training dimension and the student forms the learning dimension.Instructor: The instructor will give his/her course with a
courseware and also make the assessments. Because of this fact, for instructor criterion we handle two sub-criteria: course and course assessment. Course
Instructional Designing Planning Management Revising
Course Assessment Automated Grading Feedback Questions Pool Quizzes Student Tracking
Student: In the Web based education, in the field of learner the courseware development platform must support two main criteria: interaction and the tools that the students can use in the platform. Interaction: The related platform must include the components
that satisfy the interaction of the students (course content, interaction with other students and with the instructors). Students can access to appropriate data, databases (in or out of the campus), linking of courseware, guided decision groups. Access Discussion e-mail File Submission
Tools: Students can assess the instructional content and the program. They can also need a presentation area to make their presentations and to construct their study area. The platform also includes some tools that help students to track their progress and learn their notes online. Presentation Area Progress Tracking Self Assessment Student Skill Building
TECHNICAL: A Web-based courseware development platform must be supported wit some technical properties. These technical properties are handled in two groups as the properties essential for the development of the courses and essential for the management of the related education program Course Development Tools: Management Tools
VENDOR: There are lots of vendors for the Web-based distance education intuitions to develop educational programs. Modification Reliability Technical Support Upgrade

CONSTRUCTION OF DECISION NETWORKS
Main decision network
Instructor sub-decision network
Student sub-decision network
PAIRWISE COMPARISONSThe criteria are compared with respect to each
alternative. We ask: Which of the alternatives satisfies a criterion more? Then we ask: Which of the two criteria is more characteristic of a given alternative? As it is seen, we have two types of questions in the comparisons:For a given criterion, which of two courseware development
platforms is more desirable, and how much more?For a given courseware development platform, which of the
two criteria is more dominant or desirable for that platform, and how much more?
For the given criterion “course development tools”, which of the two courseware development platforms is more desirable; Breeze or Fle3, and how much more? And the first answer is given as Breeze is 4 times much more desirable.
RESULTS The report for how alternatives fed up
through the system gives us the values. Also, the normalized and ideal weights can be calculated. According to our decision model, WebCT is determined as the most appropriate courseware development platform based on the various main and sub-criteria.

CONCLUSIONSIn distance as well as traditional education
institutions, courseware development platform selection is a strategic decision. This managerial decision is important as it affects the success of courses. So by this study:three different courseware development
platforms are evaluated according to multicriteria
The applicability of ANP for this decision problem is demonstrated.
CONCLUSIONSWe provide a contribution in designing a new
training environment for distance education institutions based on some courseware development platforms.
The group of specialists makes pairwise comparisons in accordance to defined main and sub criteria. In the conclusion of the study, the priorities of each criterion are obtained and according to these priorities the best courseware development platform is determined as WebCT.
This methodology in our study can be used for selection of courseware development platform.
