Indirect Analogical Reasoning Components

If using different instruments obtained a different analogical reasoning component. With use people-piece analogies, verbal analogies, and geometric analogies, have analogical reasoning component consists of encoding, inferring, mapping

Problem-solving using analogical reasoning needs to involve analogical reasoning components. Several studies have discussed the analogical reasoning component in solving a mathematical problem. There are 4 components of analogical reasoning, namely encoding, inferring, mapping, and application (Sternberg, 1977). In addition to these 4 components, Sternberg writes the justification and response components. Sternberg's opinion above by adding some subcomponents in the structuring and verifying components (Ruppert, 2013). Ruppert added that the encoding and inferring components can be called structuring components. Meanwhile, within the justifying and response components are said to be verifying components. Therefore, the components of analogical reasoning according to Ruppert (Ruppert, 2013) are structuring (encoding and inferring), mapping, applying and verifying (justification and response). In addition, Thagard (Thagard, 2005) said that resolving the problem with analogical reasoning through 4 stages, namely: (1) facing the problem (target) to be solved; (2) remember the solution of the problem (source); (3) comparing source and target issues, placing relevant components in correspondence with each other; and (4) adjust to the source problem to generate a solution to the target problem.
While (Eliasmith & Thagard, 2001) divide stages in analogy reasoning into 3 stages, namely retrieval, mapping, and application. Gentner (Gentner, 1983) also identified stages in analogical reasoning into 3 stages, namely access, mapping, and evaluation and use. In solving the problem, reasoner retrieves or accesses the prior knowledge. Furthermore, the reasoning mapped prior knowledge to the problem at hand. Then, the application applies or evaluates and uses (evaluation and use) the solution to the problem at hand. English (English, 2004) argues that there are 3 stages of analogical reasoning in solving the analogical problem. First, the student must know to generalize the general relational structure of known sources or problems, and, if the source problem must be retrieved from memory. Secondly, students should know to search and be able to identify a relational correspondence between the target problem and the source problem. Third, the student must know what to do with the relational similarity between the source and the target problem. This shows that the analogous reasoning stages used by Eliasmith & Thagard, Gentner, English have similarities in their application.
Analogical reasoning stages adapted by Keane in Donoghue (O'Donoghue, 2004) are the recognition of representation, retrieval, mapping, validation, and induction. These five stages are called the five-stage model of analogy. Retrieval stages are related to memory (memory) and adaptation (adaptation), mapping stages related to reasoning and learning by abstraction, transfer stages associated with creativity and learning by transfer.
The type of analogy used in this study is the analogical problem. The analogical problem is a problem consisting of the source problem and the target problem (English, 2004). The analogical problem used in this study differs from previous researchers (Bernardo, 2001;English, 2004;Assmus, Forster, & Fritzlar, 2014). Indirect analogical problems have a very different problem between the source and the target problem. Indirect analogical problems used in this study has characteristics such as (1) the mathematical concepts between source problems and target problems different; (2) procedures in solving source problems are used to solve target problems; and (3) the context of source problems and target problems are different. Problem solving between source problems and target problems has similarities, where conceptually and procedurally resolving source problems can be used to solve target problems. Indirect analogical problems have not been used in the study of analogical reasoning (Kristayulita, Nusantara, As'ari, & Sa'dijah, 2018).

Discussion
The results show that there are additional stages in solving indirect analogical problems. The additional stages are representation and mathematical modeling. So the stages proposed by (Ruppert, 2013) to be representation and mathematical modeling, structuring, mapping, applying, and verifying. The analogical reasoning stage in resolving indirect analogical problems (Figure 10).

Figure 10. Indirect analogical reasoning
This is different from the stages already expressed by the previous expert (Sternberg, 1977;Ruppert, 2013). According (Sternberg, 1977) there are 4 stages of analogical reasoning that is encoding, inferring, mapping, and aplication. While (Ruppert, 2013) mentions analogical reasoning stages consisting of structuring (encoding and inferring), mapping, applying, and verifying (justification and response). The stages discussed by Ruppert are the development of the Sternberg analogical reasoning stage. This can be explained by the different types or forms of problems from previous studies. Previous research, source problems and target problems basically have the same type or form (Bernardo, 2001;English, 2004;Assmus et al., 2014). In this research, the source problem is symbolic and the target problem is symbolic and verbal (word problem). Furthermore, the source problem is related to the matter of quadratic equations while the target problem is related to the material of the trigonometric equations and the volume of the building of the beam space. Kristayulita, Nusantara, As'ari, & Sa'dijah (2018) indirect analogical problems need additional steps in process or analogical reasoning. The additional step is reprsentation.
Representation of a problem is a representation of a text on a problem. According to (Whitten & Graesser, 2003), text representation is a cognitive representation that has several references to elements, features, or structural patterns in explicit text. In representing the text on the problem of having the levels. According to Graesser, Millis, & Zwaan and Kintsch in (Whitten & Graesser, 2003) there are 5 levels in presenting text in the word problem: (1) the surface code retains the exact words and syntax of the text; (2) the textbase consists of words in proportional form, but ignores the exact words and syntax; (3) the situation model (or mental model) is the nonlinguistic referential content present in the text; (4) the communication is defined as capturing the pragmatic context that frames the message in the text; and (5) the related genre assigns the text to one or more rhetorical categories and uses the selected text genre to lead to an understanding The text representation of the word problem is very important since textual understanding is a fundamental component of problem-solving in an analysis that provides psychomotor judgments on some processing components (Whitten & Graesser, 2003). The problem-solving process word problem will work if the problem solver does two important things: the understanding of the text that results in the mental representation of the problem and the problem solving where the solver actually calculates the answer. So in the process of solving the problem word problem, the solver needs to have 7 capabilities of text understanding, problem representation, problem categorization, solution estimation, solution planning, procedure evaluation, and self-evaluation.

CONCLUSION
The results showed that there are stages of representation and mathematical modeling in solving indirect analogical problems. Analogical reasoning stages by Ruppert to be representation and mathematical modeling, structuring, mapping, applying, and verifying. This analogical reasoning stage used in solving indirect analogical problems. Further study is suggested to use mathematical problems that have similarities to the problems in this study. In addition, it is advisable to conduct research related to analogical reasoning error of the student in solving indirect analogical problems..
