The Effectiveness of STEM-Based MURDER Learning Model Assisted by Quizizz to Improve Students' Numeration Ability
Get PDFAbstract: 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.pp922-93

Get PDFConsidering that mathematics has an important role in learning and in everyday life, the process of learning mathematics that hones the problem solving skills of people who play a role in solving the problem, usually mathematics based on this problem uses questions that contain elements of contextual problems that intersect with students' daily lives. . The aim is to describe students' mathematical problem solving abilities on the material of a two-variable system of linear equations. Class VIII students are the subjects of this research. The indicators according to Polya are (1) Understanding the Problem, (2) Developing a Plan, (3) Implementing a Solution Plan, (4) and Reviewing the Overall Answer. The result of this research is to have an average in the medium category. In the process of completing all Polya indicators, students were able to meet all indicators, but students who had moderate mathematical problem solving abilities were only able to fulfill the indicators of planning and reviewing overall answers, while students with low mathematical problem solving abilities could not fulfill all existing indicators.Keywords: mathematical problem solving ability, system of two variable linear equations.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1839-184
Direct Instruction with SAVI Learning Model to Improve Students’ Mathematical Problem-Solving Ability: A Descriptive Study
Get PDFThis research aims to describe the ability to solve the problems of students’ mathematics and through direct learners based on SAVI is expected to provide a change in the ability to solve problems of students class VII in Junior High School 6 Bualemo, especially on triangular material. This type of research is descriptive with a qualitative approach. The subjects in this study were two class VII students. The results of this study showed that students' math problem-solving abilities were still in the "low" category. The causes are: 1) difficulty identifying the problem given, 2) difficulty determining the height of the triangle, 3) difficulty in calculating, 4) difficulty puts value into the formula, and 5) difficulty in making a partition of the triangle story problem. So, based on this information, the alternative solution is to apply direct learning based on SAVI. SAVI-based hands-on learning can provide a student's math problem-solving skills change from a "low" category to a "high enough" category. This can be demonstrated by the change in the class's grade point average from 36.78 to 81.05. Keywords: Mathematical Problem Solving Skills, Triangles, SAVI.
