| - | ===== Elaboration Theory ===== | ||
| - | |||
| - | Elaboration theory is one of the [[cognitivism|cognitivist models for instructional design]] proposed by [[http://www.indiana.edu/~syschang/decatur/bios/biographies.html|Charles Reigeluth]] and his associates in 1970s. Very well accepted, it was offering suggestions on **how to organize different types of instruction**. | ||
| - | |||
| - | The key principle is that the **content should be organized starting from the simplest** and then increasing order of complexity and that **learner has to develop a concept in which new ideas will be meaningful and well accepted**. | ||
| - | |||
| - | Elaboration theory suggests **instruction should be organized in the following eight strategies**: | ||
| - | |||
| - | * **organizing structure** (conceptual, procedural or theoretical) | ||
| - | * **sequencing content in increasing order** of complexity | ||
| - | * **within-lesson sequencing** (based on type of organizing structure: for theoretically organized instruction present ideas from **simple to complex**, for procedures present steps in their **order of appearance**, for conceptually organized instructions start **from more familiar and general concepts**). **Sequencing** content **within a lesson** can according to elaboration theory be: | ||
| - | * **topical** (topic is studied in depth before moving to the next one) | ||
| - | * **spiral** (firstly all topics are briefly introduced before going into details about each of them) | ||
| - | * **summarizers** (to review content) | ||
| - | * **synthesizers** (to enable easier meaningful integration of new knowledge) | ||
| - | * **analogies** (to enable **easier relation to prior knowledge**) | ||
| - | * **cognitive strategy activators** (images, diagrams or simply directions to mentally represent learned content) | ||
| - | * **learner control** (suggest learners to exercise control over instructional strategies and content) | ||
| - | |||
| - | According to [[http://tip.psychology.org/reigelut.html|TIP]] Reigeluth (1983) provides the following summary of a theoretical epitome for an introductory course in economics: | ||
| - | |||
| - | - Organizing content (principles)- the law of supply and demand | ||
| - | * An increase in price causes an incease in the quantity supplied and a decrease in the quantity demanded. | ||
| - | * A decrease in price causes a decrease in the quantity supplied and an increase in the quantity demanded. | ||
| - | - Supporting content - concepts of price, supply, demand, increase, decrease | ||

| - | ===== Critics ===== | ||
| - | |||
| - | |||
| - | One of the critics or **limitations of this model comes from distinguishing between only three different knowledge types** (theories, procedures and concepts). This is a simplifying design constraint, yet there are [[http://rer.sagepub.com/content/61/3/315.abstract|surveys]] that resulted in different, sometimes significantly larger number of knowledge categories. | ||
| - | |||
| - | Another critic of this theory bases on the used assumption that most general concepts are always closest to learner's prior understanding, which has shown to be unfounded by [[http://carbon.ucdenver.edu/~bwilson/elab.html|Wilson and Cole]]. | ||
| - | |||
| - | Critics resulted in a new approach presented by Reigeluth in 1999, called [[simplifying conditions method]] (SCM). | ||
