Penalaran Analogi Peserta Didik SMP dalam Menyelesaikan Dua Masalah dengan Kesamaan Permukaan Rendah

2023-08-19T13:03:52+00:00

Analogical reasoning is a process of identifying two problems that aim to produce knowledge by associating relevant concepts and facts and adapting them so that they can solve more complex problems. Low surface similarity does not play a significant role in solving analogical reasoning. This type of research was carried out descriptively with qualitative methods with the aim of describing students' reasoning in solving analogy problems with low surface similarity. The research was conducted at one of the junior high schools in Sidoarjo with three selected students. Research data were analyzed using indicators that had been made by researchers. The data from the research results gave rise to three students who have uniqueness in analogical reasoning. There are two peculiarities found, namely the peculiarities with general cases and the peculiarities with special cases. The low surface similarity in analogy problems has an impact on students in the form of different stages of analogical reasoning that are passed by the three students. Students with general characteristics have stages of linear analogy reasoning. Students with special case characteristics have dynamic analogical reasoning stages. Identifying is done by students by identifying characteristics and concluding the relationship between the two problems. Mapping is done by students by mapping information related to analogy problems. At the time of applying the answers to the source problem to the target problem, there were two students with special characteristics who returned to the previous stage because they found it difficult. Verifying has been done by each student, but students with special cases have beliefs that are contrary to the results of the answers. So, the use of source problems and target problems that have low surface similarities can be used with the condition that the structure of the answers between the two problems must be analogous to each other.

Argumentasi Analogis Siswa SMA pada Masalah Analogi Tipe Prediktif

2023-08-26T02:08:30+00:00

Analogy helps students find solutions to problems that involve new knowledge by referring to previously learned knowledge. Analogical argumentation plays a crucial role in supporting solutions to interconnected problems. Analogical argumentation itself is defined as the process of analyzing information from two similar and interconnected problems to provide logical reasons to justify conclusions. This research aims to describe the analogical argumentation of high school students on predictive analogy problems. This study uses a descriptive qualitative approach. The research subjects are three 10th-grade students from a public high school in Bojonegoro, selected based on the criteria of the source problem 1) claim being supported by grounds and warrant, 2) claim being supported by grounds, warrants focusing on congruence, and backing, 3) claim being supported by grounds, warrants focusing on square rotation, and backing. The data from the analogical argumentaion task and interviews were analyzed using predefined indicators by the researcher. The research findings indicate that students' analogical argumentation begins with identifying information, questions, and identical concepts between the two problems. Then, students make assumptions about the structure of the target problem in relation to the source problem, search for similarities in geometric properties, and discover relationships between the questions in both problems. Students engage in appropriate argumentation based on the source problem to predict conclusions for the target problem. They construct grounds and warrants based on the structure of analogical argumentation. Students tend not to double-check their answers because they are already confident with their stated conclusions.
