Peningkatan Kemampuan Literasi Matematika Melalui Pendekatan Problem Based Learning Bermuatan Penilaian Portofolio

Abstract

Currently, the government is aggressively optimizing students' literacy skills, including mathematical literacy skills. Today's problem is that the dominant students still have low mathematical literacy skills. Therefore, one solution is to apply a Problem Based Learning (PBL) model based on portfolio assessment. This study aims to determine the difference between students' mathematical literacy skills taught using the PBL learning model about portfolios and students' mathematical literacy skills using the direct learning model. Quasi-experimentation is the type of research using the Posttest Only Control Group Design. The population of the study was the seventh-grade students of SMPN 2 Cibal, who found 96 people spread over 3 classes. Samples were taken from the population in a randomized manner so that 32 students of class VIIC were obtained as the experimental group and 32 students of class VIIA as the control group. Data was collected from description testing and also equipped with student portfolio assessment results. The results of data analysis showed that the literacy skills of students who were taught using the PBL learning model showed a better portfolio than the literacy skills of students who used the direct learning model.

Meta-Analysis Study: The Effect of Problem Based Learning (PBL) on Students' Mathematical Literacy Skills

“…The next research was conducted outside Java, precisely in the West Cibal sub-district area, East Nusa Tenggara Province (NTT). This research was conducted by Kurnila et al, (2022).…”

Pengaruh Model Problem Based Learning Terhadap Kemampuan Berpikir Kreatif Matematis Siswa pada Materi Kubus dan Balok

“…Riset-riset yang membahas tentang pelibatan model Problem Based Learning dalam pembelajaran matematika banyak ditemukan dalam berbagai kasus, seperti Tarmizi dan Bayat [9] yang mencoba mengolaborasikan model Problem Based Learning dengan matematika dalam perspektif kognitif dan Abdullah, dkk [10] yang memperlihatkan atribut afektif pembelajaran statistika dengan model Problem Based Learning. Beberepa riset juga menerapkan model Problem Based Learning untuk meningkatkan kemampuan siswa, diantaranya untuk meningkatkan kemampuan pemecahan masalah matematis dan kepercayaan diri siswa [11] [12], kemampuan komunikasi siswa [13], keterampilan berpikir kritis matematis [14], termasuk meningkatkan kemampuan literasi matematika [15]. Riset terbaru yang berkaitan dengan model ini dilakukan oleh Simarmata [16] yang mecoba kemampuan pemecahan masalah siswa dengan melibatkan model Problem Based Learning dan model keratif Problem Solving, kemudian Goni, dkk [17] menunjukkan adanya pengaruh penerapan model Problem Based Learning terhadap hasil belajar matematika secara umum.…”

Students' Mathematical Communication: The Effectiveness of Somatic, Auditory, Visual, Intellectual Learning and Problem-Based Learning Model on Number Pattern

“…Permendikbud Number 34 of 2018 concerning Standards for the Primary and Secondary Education Process said that PBL is one of the learning models recommended in the 2013 Curriculum in addition to Discovery Learning (DL) and Project Based Learning (PjBL). The advantage of the PBL model is to suppress student activity by using real problems as something that learners learn to get important concepts so that they can communicate in mathematics learning (Kurnila et al, 2022). PBL model makes learners more active so that it can improve Learners' mathematical communication ability (Iskandar, Ermiana, & Rosyidah, 2021).…”
