The Data Package in Learning Mean Using LSLC and PMRI

Abstract

This study aims to produce statistical learning designs in the introduction of the concept of average values and knowing student learning outcomes in learning average values by previously learning about the presentation of data consisting of tables and diagrams through learning trajectories and what happens during the learning process. This learning is based on Lesson Study for Learning Community (LSLC), the approach of Indonesian Realistic Mathematics Education (PMRI). This study uses a type of Design Research method research design type of validation study, which involves in MTs 1 in Palembang. There are three stages in design research type validation studies namely Preparing for the experiment in the form of literature study and the design of the Hypothetical Learning Trajectory (HLT); Design experiment in the form of a Preliminary Teaching Experiment (Pilot Experiment) and Teaching Experiment; and Restrospective analysis. The instruments used were written test, video and field notes. The results of learning experiments show that the design of learning provided has helped students understand the concept of Mean.

Students’ mathematical reasoning skills on number pattern using PMRI and collaborative learning approach

“…A learning approach that emphasizes the presentation of contextual problems is Realistic Mathematics Education (RME) so that during learning activities, students will feel more fun and meaningful (Narmi et al, 2020). It is in line with the thoughts of Rahayu and Putri (2021) that the learning process carried out by involving the context makes the knowledge that students learn meaningfully. RME is known in Indonesia as "The Indonesian Realistic Mathematics Education" (PMRI).…”

“…This problem is related to real problems, so this is in line with the understanding of PMRI, which is a theory based on real problems (Zulkardi & Putri, 2010). According to Rahayu and Putri (2021), the learning process involving the context makes students learn meaningfully. In sharing tasks and jumping tasks, students who do not understand are required to ask for help from their friends who understand by saying, "Please teach me" (Sato, 2014).…”

Junior high school students’ mathematical reasoning skills on integer using PMRI and collaborative learning

“…PMRI's principles: guided reinvention or progressive mathematizing, didactical phenomenology, and self-developed (Zulkardi & Putri, 2010). Rahayu and Putri (2021) that a student's knowledge will be relevant if the learning process is carried out in the context of solving the problem. To make learning more exciting, what is offered begins with a real background (Putri, 2015).…”

“…Learning mathematics will be more enjoyable and relevant if it can be related to everyday life so that students may better comprehend the material. According to Rahayu and Putri (2021), a student's knowledge will be more meaningful if the learning process is conducted in a context. As a result, the appropriate strategy is required for the learning process to link to the real world (Mairing, 2016).…”
