Abstract

This study aims to determaine the profile of the representation ability of juniorhigh school students in terms of learning styles. This type of research wasdescriptive qualitative research. The subjects taken were three junior highschool students of eight grade, each of whom had a visual learning style, andauditory learning style, and kinesthetic learning style. The data was collectedusing a learning style scale, written tests, interviews and documentation. Thedata analysis technique was carried out in 3 stages, reduction, datapresentation, and drawing conclucions or verification. The validity of the dataused time triangulation, comparaing the results of the representation abilitytest with the results of interviews in the first and second stages. The analysiswas developed based on indicators of representational ability by taking inroaccount student learning styles. Based on the results of the analysis, it isknown that subjects with visual, auditory and kinesthetic learning styles havelow verbal representation abilities.

Abstract

Students' problems in understanding mathematical concepts to solve word problems of the hots type became the background of this study. The purpose of this research is to determine the ability to understand mathematical concepts of students with a cognitive style in solving hot type word problems. The population used in this study were students of SMP Negeri 2 Karangawen. While for the withdrawal of samples using purposive sampling technique the sample was taken from 26 student namely 2. This study used qualitative research methods which in its implementation used observation, tests, and interviews. Data analysis is carried out interactively and takes place continuously and through 3 stages, namely data reduction, data presentation, and conclusion drawing. The results revealed that subjects who have a reflective cognitive style have a better concept understanding ability in problem solving HOTS model questions, compared to students with impulsive cognitive style. Therefore, it is important for students to practice HOTS model problems in order to improve good concept understanding.

Abstract

Pendidikan memiliki peran penting dalam menciptakan sumber daya manusia berkualitas. Proses pembelajaran yang efektif sangat penring untuk menghasilkan lulusan yang kompeten. Penelitian ini bertujuan meningkatkan kognisi matematis siswa SMA Negeri 8 Semarang melalui model Problem Based Learning (PBL) berbantuan LKPD-QR Code. Metode yang digunakan adalah Penelitian Tindakan Kelas (PTK) dengan dua siklus, masing-masing terdiri dari perencanaan, tindakan, observasi, dan refleksi. Pada Siklus I, hasil observasi menunjukkan bahwa sebagian besar siswa memiliki kognisi matematis rendah. Setelah refleksi, pada Siklus II dilakukan perbaikan dengan penggunaan LKPD berbasis QR Code. Hasilnya, terjadi peningkatan kognisi matematis siswa dengan skor rata-rata naik dari 76,11 pada Siklus I menjadi 81,33 pada Siklus II. Persentase ketuntasan juga meningkat dari 47,22% pada Siklus I menjadi 75% pada Siklus II. Kesimpulannya, penerapan model PBL berbantuan LKPD-QR Code dapat meningkatkan kognisi matematis siswa di SMA Negeri 8 Semarang.
