Abstract

Rotation (rotation) is one of the materials in the transformation of geometry. Rotational learning can be the basis for student understanding geometrically because of its dynamic nature. Rotational learning can allow students to relate some geometric concepts such as congruence and equivalence. The study aims to explore the students’ inductive reasoning in rotation problem through the context of songket Palembang pattern in class. This research is related to the Indonesian Realistic Mathematics Approach (PMRI) as a learning approach used. The methodology used in this study is Design Research type validation studies consisting of three stages: preliminary design, experimental design, and retrospective analysis. The study was conducted for IX grade students of SMP Negeri 1 Palembang. The learning path (Hypothetical Learning Trajectory) in design research plays an important role as a research design and instrument. The Hypothetical Learning Trajectory was developed together with a series of activities using the contet of songket Palembang pattern such as pucuk rebung pattern, lepus pattern, lintang pattern, etc. Data collected in the form of video recordings and photos during the learning process, student interviews, student work results, discussion results, and field notes at each meeting. The instruments used include documentation in the form of video recordings and photos, interview sheets, student activity sheets, field note sheets, and the Hypothetical Learning Trajectory (HLT). Media used in this study was the students’ worksheet. The result of this study indicated that exploration using the context of songket Palembang patterns can help inductive reasoning ability on students when solving rotation problem. The conclusion of this study is the use of songket Palembang pattern as starting point in mathematics learning in rotation material helps the students to explore their inductive reasoning skill in solving rotation problems.DOI : https://doi.org/10.22342/jpm.16.1.14304.57-72

Abstract

Rotation is an essential part of geometric transformations. This research aims to produce a learning trajectory of rotation material and determine the role of activities in learning the rotation which is expected to be able to support students understanding the concept of rotation learning in grade IX. The approach used is Pendidikan Matematika Realistik Indonesia (PMRI) with Lesson Study for Learning Community (LSLC) as learning system. The method used in this research is a design research type validation study. This research was conducted in limited face-to- fece meetings at secondary school number 1 Palembang during the pandemic and involved 13 students of class IX. The data were collected using video recordings and photos taken during the learning process, student interviews, student work, discussion results, and field notes at each meeting. The results of this study indicate that the learning trajectory can support the informal to formal concept of rotation, including the activity of recording the starting point and endpoint, analyzing and interpreting changes of starting and endpoints using one’s language, and writing the rotation formula. Therefore, it can be concluded that a series of activities by exploring the Palembang songket fabric motif plays a role in helping students understand the concept of rotation easily and allows them to produce rational imaginations and fun learning.
