 Structural learning theory suggests that structures (problems) that a learner must learn, need to be formed as **rules** performed on a **domain**.
-A domain here is defined as a set of characterizing **inputs** and **outputs**. Inputs and outputs can be anything, even a process, an idea or a concept. For example: list of verbs (input) -> present participles (output).

 Operations performed on given inputs are called rules, and they generate unique outputs. Rules can contain different levels of abstraction and are always defined with three parameters:

 Rules can be simplified into **lower-order rules** (//atomic components//) which represent most basic concepts learner needs to know when dealing with a problem from given domain. By combining these atomic components and application of more complicated to lower order rules new **higher-order rules** are derived. Higher-order rules are rules which can have other rules as inputs or outputs (for example mathematical theorems) and they can be used to solve complex problems in the whole domain.

+  - The first step is to identify problem domain inputs and outputs, or even only outputs (representative problems).
+  - Rules should be defined and explained on each representative problem. Problem domain can be both well- and ill-defined((An ill-defined domain is one in which rules are quite simple, yet there is no direct complete solution like chess, or poetry writing.)). In case of an ill-defined domain, it should be divided into well-defined sub-domains which can generate at least one solution rule.
+  - Each solution rule should be converted into a new higher-order problem and new higher-order rules for solving them.
+  - Redundant rules should be eliminated and the whole process repeated until simple enough rules are reached.
+An important part of the theory is also **prior knowledge (rules)** of the learner, that will **enable construction of new rules**. This knowledge can be examined by instructor, that can be both human or artificial.

+An example of application of structural learning on learning how to subtract:((Suggested by Scandura in [[http://books.google.hr/books?id=qlF9AAAAMAAJ&q=Problem+Solving:+A+Structural/Process+Approach+with+Instructional+Applications&dq=Problem+Solving:+A+Structural/Process+Approach+with+Instructional+Applications&hl=hr&ei=GpuATeSrMs7esgbhvfT4Bg&sa=X&oi=book_result&ct=result&resnum=2&ved=0CCwQ6AEwAQ|Scandura, J.M. Problem Solving: A Structural/Process Approach with Instructional Applications. NY: Academic Press. 1977.]]. Cited in [[http://tip.psychology.org/scandura.html|TIP: Structural Learning Theory (J. Scandura)]]. Retrieved March 16, 2011.))
-  - A hierarchy of rules should be defined for the domain. Problem domain can be both well- and ill-defined((An ill-defined domain is one in which rules are quite simple, yet there is no direct complete solution like chess, or poetry writing.)). In case of an ill-defined domain, it should be divided into well-defined sub-domains which can generate at least one rule.
+  - Select a representative sample of subtraction problems such as 9-5, 248-13, or 801-302.
+  - Identify the minimal capabilities of the learners: be able to recognize the digits 0-9, minus sign, column and rows. Then identify rules for solving each of the subtraction problems. For example, one of the rules can be that if the last digit of the minuend is smaller than a corresponding digit of the subtrahend, the next left digit in minuend is decremented by one.
-Domain definition is followed by **construction of hierarchy of rules** for well-defined domains. Rules should be explained on prototype problems, but can also leave some **gaps** in problem solving procedure, which **are then converted into higher-order problems** containing gap rules. Higher-order rules are then used to fill the gap, but can also validate lower level rules.
+  - Identify higher-order rules and eliminate other rules they subsume. For subtraction this means the rule mentioned under (2) should be generalized for any digit of the minuend and corresponding digit of the subtrahend, not just the last one.
+  - Reconsider the resulting rules from (3) and generalize them to account for all problems within the domain. In the case of subtraction we could generalize the problem to subtraction of numbers in different bases.
-An important part of the theory is also **prior knowledge (rules)** of the learner, that will **enable construction of new rules**. This knowledge can be examined by instructor, that can be both human or artificial.
 Structural learning theory's applications have been made in **mathematics** and **language learning**.
