PENGARUH MODEL PROBLEM BASED LEARNING BERBASIS HOTS BERBANTUAN MEDIA LEGO TERHADAP KEMAMPUAN METAKOGNISI MATEMATIS MATERI PECAHAN PADA PESERTA DIDIK KELAS III SD SEKECAMATAN SUKARAMI PALEMBANG

Abstract

This study aims to determine the effect of implementing the HOTS-based Problem

Based Learning model assisted by Lego media on mathematical metacognition

abilities in fraction material in grade III students of Public Elementary Schools in

Sukarami District. Research samples were taken using the Cluster Random

Sampling technique. The two selected schools were SD Negeri 127 Palembang,

namely class IIIA as the control class and SD Negeri 128 Palembang, namely

classes IIIA and IIIB as the experimental. The type of research used is True

Experimental with a quantitative approach. This research uses a Pretest Posttest

Control Group Design form.The research hypothesis was tested using a one-way

ANOVA test with the F-test statistical test and continued with the t-dunnet further

test. The results of the study concluded that: (1) there is a significant influence of

mathematical metacognitive ability between students who receive learning with the

HOTS-based Problem Based Learning learning model assisted by Lego media,

HOTS-based Problem Based Learning without Lego media and conventional; (2)

there is a difference in the average mathematical metacognitive ability of the

HOTS-based Problem Based Learning group assisted by Lego media and HOTS-

based Problem Based Learning without Lego media; (3) The average

mathematical metacognitive ability of the HOTS-based Problem Based Learning

group assisted by Lego media is higher than the group given the conventional

method; (4) The average mathematical metacognitive ability of the HOTS-based

Problem Based Learning group without Lego media is lower or the same as the

mathematical metacognitive ability of the group with the conventional method.
