The reasoning is the ability to find a way to get the truth. In terminology, logic is the science that governs the process of human thinking so that the results presented can reach the truth. So it can be concluded also that by reasoning, humans can make an argument that is absolute and can be accepted by others through logical thinking. This research was conducted to determine the mathematical reasoning ability of MTs class 8 students on Triangle and Quadrilateral material based on indicators of mathematical reasoning ability that is to draw a logical conclusion and compose an argument, analogical reasoning, transductive reasoning, deductive reasoning, generalization and estimate answers, solutions or tendency with non-routine troubleshooting. The research method used is descriptive qualitative with data to be analyzed is qualitative data in the form of written and oral answers obtained from the written test. This research was conducted in MTs PPI 38 Padalarang with the subject of this research is class VIII-A which amounted to 31 people. Based on the results of research, students' mathematical reasoning abilities on MTs PPI 38 Padalarang are classified as sufficient. This is because there are some reasoning indicators that still need to be improved especially on analytical reasoning and generalization indicator as stated in the table which has been described.

Reasoning ability refers to the power and effectiveness of the processes and strategies used in drawing inferences, reaching conclusions, arriving at solutions, and making decisions based on available evidence. The topic of reasoning abilities is multidisciplinary—it is studied in psychology (differential and cognitive), education, neuroscience, genetics, philosophy, and artificial intelligence. There are several distinct forms of reasoning, implicating different reasoning abilities. Deductive reasoning involves drawing conclusions from a set of given premises in the form of categorical syllogisms (e.g., all x are y) or symbolic logic (e.g., if p then q). Inductive reasoning involves the use of examples to suggest a rule that can be applied to new instances, invoked, for example, when drawing inferences about a rule that explains a series (of numbers, letters, events, etc.). Abductive reasoning involves arriving at the most likely explanation for a set of facts, such as a medical diagnosis to explain a set of symptoms, or a scientific theory to explain a set of empirical findings. Bayesian reasoning involves computing probabilities on conclusions based on prior information. Analogical reasoning involves coming to an understanding of a new entity through how it relates to an already familiar one. The related idea of case-based reasoning involves solving a problem (a new case) by recalling similar problems encountered in the past (past cases or stored cases) and using what worked for those similar problems to help solve the current one. Some of the key findings on reasoning abilities are that (a) they are important in school, the workplace, and life, (b) there is not a single reasoning ability but multiple reasoning abilities, (c) the ability to reason is affected by the content and context of reasoning, (d) it is difficult to accelerate the development of reasoning ability, and (e) reasoning ability is limited by working memory capacity, and sometimes by heuristics and strategies that are often useful but that can occasionally lead to distorted reasoning. Several topics related to reasoning abilities appear under different headings, such as problem solving, judgment and decision-making, and critical thinking. Increased attention is being paid to reasoning about emotions and reasoning speed. Reasoning ability is and will remain an important topic in education.

This study aims to reveal the condition of students' reasoning abilities based on the way students argue. This research uses a qualitative-descriptive approach. The subjects in this study were 3 students of junior high school with high reasoning abilities and 3 students with low reasoning abilities who viewed the reasoning ability scores when providing problem solving solutions on the written test. The data obtained in this study were in the form of students' written test scores and the results of student interviews. Interviews were conducted to bring up students 'ability to argue that describe and reveal the condition of students' reasoning abilities in the process of solving problems. The results of students 'arguments are analyzed and adjusted to the model of StephenToulmin's argument which reveals that there are 6 components of the argumentation to show the seriousness of students in arguing in order to obtain valid argument results to assess students' reasoning abilities. The arguments from students succeeded in uncovering 4 conditions that describe the conditions of students' mathematical reasoning abilities. These conditions are: 1) Students who show high reasoning ability in written tests and are able to show their reasoning process in the arguments that are brought up, 2) Students who show low reasoning abilities in written tests but are able to show their reasoning processes in the arguments that are brought up, 3) Students which shows a high reasoning ability in a written test but have not been able to demonstrate the reasoning process in the arguments that are brought up, and 4) Students who show a low reasoning ability in a written test and have not been able to demonstrate their reasoning process in the arguments that are brought up.

Analogous Reasoning

<p>Analogical reasoning is the ability to solve problems by finding similarities between two objects, namely source and target objects. The purpose of this study was to determine the analogical reasoning profile of students at SMA N 16 Semarang. This study is included in a qualitative study with data collection techniques used in surveys by working on analogical reasoning problems. The research subjects were 100 students of class X. The results found in this study were the category of analogical reasoning ability of students of SMA N 16 Semarang low with a frequency of 74 and a percentage of 73.6%. The low ability of analogical reasoning students is influenced by the lack of learning methods that encourage students in problem-solving using analogies, besides analogies have two sides if understood will facilitate students' understanding of concepts, but if it cannot be understood misconceptions occur so teachers rarely use analogous reasoning in explaining material abstract. Therefore it is necessary to have an understanding and experience of the teacher to build this ability by using learning methods that support analogical reasoning abilities.</p>
