 ===== What is structural learning theory? =====
-Structural learning theory suggests that structures (problems) that a learner must learn, need to be formed as rules. Those 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 can be used to solve complex problems in the whole domain.
+Structural learning theory suggests that structures (problems) that a learner must learn, need to be formed as **rules** performed on a **domain**.
-Rules, according to the structural learning theory have three parameters:
+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:
   * **domain** - its allowed **inputs**,
   * **range** - its expected outputs, and
   * **procedure** - the sequence of **operations** to perform **on the inputs**.
-In accordance with structural learning theory, first step in instructional design or learning is **definition of the problem domain through structural analysis**. 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. Domain sets the inputs and desired outputs for problem solving.
+For example: a rule //form present participle// has the domain of all English verbs, the range of present participles and the procedure of adding "-ing" ending to the verb.
-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.
+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.
-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 further attempts to identify components crucial for solving the given problem and is based on the procedure called //structural analysis//. Structural analysis is performed in the following steps:
-Structural learning theory's applications have been made in **mathematics** and **language learning**.
+  - 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.
