Abstract

Abstract: The numeracy of 10th-grade students at SMAN 3 Slawi is still not optimal and needs improvement. This is because students are not accustomed to dealing with non-routine problems. This research aims to determine the effectiveness of the STEM-based MURDER learning model assisted by Quizizz in improving students' numeracy. In this study, the proportion test of student completeness obtained a Sig. value of 0.004, indicating that the proportion of students class experimental exceeded the classical completeness, reaching 42%. In the test of average differences, a Sig. value of 0.004 was obtained, meaning that the numeracy ability of the experimental group was higher than control group. In terms of improvement, the N-Gain test resulted 0.28, which falls into the interval 〈g〉 < 0.3, indicating that the improvement in students' numeracy using the STEM-based MURDER learning model assisted by Quizizz is relatively low. Keywords: numeracy, STEM, MURDER, quizizz. Abstrak: Numerasi siswa kelas X SMAN 3 Slawi masih belum optimal dan perlu ditingkatkan, hal tersebut terjadi karena siswa tidak terbiasa dengan permasalahan berupa soal non-rutin. Penelitian ini bertujuan untuk menentukan efektivitas model pembelajaran berbasis STEM MURDER yang dibantu oleh Quizizz dalam meningkatkan numerasi siswa. Dalam penelitian ini, uji proporsi ketuntasan siswa diperoleh nilai Sig. 0,004 dengan demikian proporsi ketuntasan siswa yang dikenai pembelajaran MURDER berbasis STEM berbantuan Quizizz melampaui tuntas secara klasikal mencapai 42%. Pada uji perbedaan rata-rata diperoleh nilai Sig. 0,004 yang artinya kemampuan numerasi siswa kelas eksperimen lebih dari numerasi siswa kelas kontrol. Dalam peningkatannya dilakukan dengan uji N-Gain diperoleh N-Gain score sebesar 0,28 berada pada interval 〈g〉 < 0.3, bahwa peningkatan numerasi siswa dengan menggunakan model pembelajaran MURDER berbasis STEM berbantuan Quizizz tergolong rendah.  Kata kunci: numerasi; MURDER; STEM; dan quizizz. DOI: http://dx.doi.org/10.23960/jpmipa/v24i4.pp922-931

Abstract

Academic resilience helps students overcome learning challenges and stay motivated in understanding complex biology materials. Computational thinking skills enable students to break down complex biology problems logically and structured, while the use of multirepresentations such as diagrams and graphs facilitates the understanding of abstract concepts. Biological literacy has a very important urgency for students because it plays a role in equipping them with the ability to understand, analyze, and apply biological concepts in everyday life. In the era of globalization and rapid development of science, biological literacy is an important basis for making intelligent decisions, especially related to environmental, health, and sustainability issues. The objective of this study is to investigate the influence of academic resilience on the biological literacy of students by means of computational thinking and multirepresentations. It is hypothesized that students' capacity to surmount intricate biology learning obstacles is enhanced by their high academic resilience. This study examines the correlation between academic resilience, computational thinking, multirepresentations, and biological literacy in high school pupils in Mataram City, Indonesia, utilizing quantitative methods and Structural Equation Modeling (SEM) analysis. The findings indicated that academic resilience has a substantial impact on the biological literacy of students (p < 0.05), both directly and through the mediation of computational thinking abilities and the use of multirepresentations. Computational thinking assists students in the deconstruction of intricate biological problems, while multirepresentations, such as diagrams and graphs, facilitate comprehension of abstract biological concepts. This study underscores the significance of fostering academic resilience, computational thinking, and visual representations in order to enhance students' biological literacy, thereby facilitating the development of more effective and adaptive biology learning strategies.      Keywords: academic resilience, biology literacy, computational thinking, multirepresentation, students.

Abstract

This study aims to analyze the effect of learning based on concreteness fading and multi-representation on prospective teacher students' understanding of geometric optics concepts. The research sample consisted of 40 prospective physics teacher students, selected using the total sampling technique, with 20 students in each experimental and control group. The experimental group received learning with concreteness fading and multi-representation approaches, while the control group received conventional learning. The research instrument was a concept understanding test in the form of descriptions, which was tested for content validity and reliability using the inter-rater reliability method, yielding a Cohen's Kappa coefficient of 0.68. Data analysis techniques included independent samples t-test, ANCOVA, and N-gain. The results of the independent samples t-test showed that, in the posttest, there was a significant difference (p = 0.008 < 0.05) with the average score of the experimental group (M = 21.55) being higher than that of the control group (M = 19.10). ANCOVA test results showed that learning with concreteness fading-multi representation significantly affected students' concept understanding after controlling for the pretest score (p = 0.009 < 0.05). Additionally, the N-Gain test results indicated increased concept understanding in the experimental class (0.75, high category) and the control class (0.56, medium category). Initially, many students struggled and relied solely on one form of representation to explain geometric optics problems. However, after learning, they began to utilize various interrelated representations, including diagrams, texts, and mathematical equations. The findings in this study confirm that learning with concreteness fading and multi-representation approaches is effective in improving understanding of geometric optics concepts.      Keywords: conceptual understanding, concreteness fading, geometric optics, multi-representation, physics learning.
