  1. 1. -Robert Hillis
  2. 2. Instructional Design Instructional Design is the development, implementation, and assessment of knowledge curriculums determining if they are cost effective, successful, and able to be implemented.
  3. 3. Instructional Design Instructional Design does not encompass or embrace one particular method nor does it favor a specific method over another Instructional Design takes is the practice of developing instruction and implementing it in the best way possible utilizing the best methods available
  4. 4. Instructional Design Models There are several different approaches to Instructional Design Example:  ADDIE Process  Rapid Prototyping  Dick and Carey Systematic Approach  Instructional Development Learning System (IDLS)  Smith/Ragan  Morrison/Ross/Kemp  OAR Model of Instructional Design in higher education
  5. 5. Dick and Carey SystematicApproach Dick and Carey refers to the model that was designed in 1978 by Walter Dick and Lou Carey Dick and Carey outlined their approach in their book “The Systematic Design of Instruction” Their model addresses instruction as an entire system from development to assessment of success
  6. 6. Dick and Carey SystematicApproach 9 components: 1. Assess needs to identify instructional goals 2. Conduct Instructional Analysis 3. Analyze learners and contexts 4. Write performance objectives 5. Develop Assessment Instruments 6. Develop instructional strategy 7. Develop and select instruction 8. Design and conduct formative evaluation 9. Revise Instruction
  7. 7. Dick and Carey SystematicApproach
  8. 8. Dick and Carey SystematicApproach The final component of the Dick and Carey model is the 10th step which is the cumulative evaluation of the effectiveness of instruction More and more companies are beginning to measure the success of their instructional design models in order to ensure effectiveness
  9. 9. Rapid Prototyping Rapid Prototyping in reference to Instructional Design can be described as the continual design-evaluation cycle throughout the process Utilizing this model means that products are continually improved upon as the cycle continues
  10. 10. Rapid Prototyping Spiral Model 1. Concept definition 2. Implementation of a skeletal system 3. User evaluation and concept refinement 4. Implementation of refined requirements 5. User evaluation and concept refinement 6. Implementation of refined requirements 7. repeat
  11. 11. Rapid Prototyping
  12. 12. Rapid Prototyping Advantages:  Allows for better communication between designer and user  User is able to offer immediate feedback thus resulting in better development  Allows for more flexibility in instruction and allows for problems to be caught early on in the process
  13. 13. Rapid Prototyping Disadvantages:  Some feel that it is not effective because it is not utilizing the real product, it is utilizing a prototype  Some feel steps are overlooked due to the rapid response of the model and that it can lead to endless revisions
  14. 14. Dick and Carey vs. RapidPrototyping There are strengths with each and there are weaknesses with each Dick and Carey can be a very tedious, very specific styled model where as Rapid Prototyping can be very simply and move very quickly Dick and Carey can involve many facets of organization versus Rapid Prototyping where there may be only one or two layers that are being utilized Dick and Carey executes components iteratively and in parallel where as Rapid Prototyping executes them in a cyclical pattern
  15. 15. Which to Choose There is no right or wrong answer just as in implementing instruction, it depends on the audience, situation, and task at hand What may work for one situation wont work for another. The best thing to do is to evaluate what is needed for the instructional design and move forward based upon that analysis
