Abstract

This research aims to determine the difference in the average increase in students' mathematical problem solving ability scores between the experimental class which was given the Means-Ends Analysis strategy through the Jigsaw learning model and the control class which received conventional learning for class X students at MAN 1 Cilegon City. The samples were selected from two classes using cluster random sampling technique. This type of research is quasi-experimental with a non-equivalent control group research design. The instrument used in this research was a test of mathematical problem solving abilities. The results of the research show that there are differences between classes that receive learning using the Means-Ends Analysis strategy through the Jigsaw learning model and classes that receive conventional learning. This is shown by the results of the independent sample t-test with a t-value of 2.480 and a p-value of 0.008. This can be confirmation that the Means-Ends Analysis strategy through the Jigsaw learning model has a significant influence on problem solving.

Abstract

Abstrak Penelitian ini bertujuan untuk mengembangkan instrumen tes yang valid dan reliabel untuk mengukur kemampuan berpikir kritis matematis siswa SMA pada materi SPLTV dalam konteks personal. Penelitian ini menggunakan metode Research and Development (R&D) dengan model ADDIE yang meliputi tahap analisis, desain, pengembangan, implementasi dan evaluasi. Instrumen tes dikembangkan dan divalidasi oleh ahli dan diujicobakan pada 34 siswa kelas X MAN 1 Kota Cilegon. Hasil uji coba menunjukkan bahwa seluruh butir soal memiliki validitas tinggi (0,79 – 0,93), nilai reliabilitas , tingkat kesukaran sedang (0,33 – 0,60), serta daya pembeda yang bervariasi dari cukup hingga baik. Kata kunci: Instrumen tes, Berpikir kritis matematis, SPLTV Abstract  This study aims to develop a valid and reliable instrumen test to measure high school students' critical thinking skills on the topic of Three-Variable Linear Equation Systems (SPLTV) in a personal context. The study employed a Research and Development (R&D) method using the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The instrumen test was developed and validated by experts and tested on 34 tenth-grade students at MAN 1 Kota Cilegon. The trial results showed that all test items had high validity (0.79 – 0.93), a reliability score (α = 0.85), moderate difficulty level (0.33 – 0.60), and discriminating power ranging from fair to good.  Keywords: Instrumen test, Critical Thinking, SPLTV
