![]() ![]() This shows the influence of critical thinking on mathematics learning outcomes, while the coefficient of determination (r2) of 0.409 or 40.9%. Then the results of the study showed that there was an influence of critical thinking on mathematics learning outcomes, indicated by statistical analysis that produced a path coefficient (pxy) value of 0.64. The average value on the critical thinking variable was 109.7 and the average value on the mathematics learning variable was 68.1. Test data analysis requirements using the test for normality, homogeneity, and linearity. The instrument validity test uses the Person Product Moment correlation formula and the reliability test uses the Cronbach Alpha formula. The research was carried out in the first semester of the 2019/2020 school year. Bogor City Pondok Rumput Elementary School consisting of 49 respondents. ![]() The subjects of this study were students of class IV-A. The main objective of this research is to find out the positive influence between critical thinking and mathematics learning outcomes. THE EFFECT OF CRITICAL THINKING ON MATHEMATICS LEARNING OUTCOMESThis research was conducted using an associative quantitative research approach with a type of causal approach consisting of two variables namely critical thinking as an independent variable and mathematics learning outcomes as the dependent variable. Sehingga dapat disimpulkan bahwa LKS berbasis problem based learning memenuhi kriteria valid, praktis, memiliki efek potensial, dan bisa digunakan dalam proses pembelajaran Siswa (94,2 %) dalam kategori telah tuntas sedangkan (5,8%) belum tuntas. LKS matematika bebasis PBL memiliki efek potensial terhadap hasil belajar siswa. ![]() Kepraktisan LKS berbasis PBL mendapatkan respon praktis dengan skor rata-rata seluruh uji kepraktisan yaitu 3,28. Model pengembangan yang digunakan dalam penelitian ini adalah model pengembangan 4D untuk mengembangkan LKS menggunakan metode Research and Development (R&D) Berdasarkan hasil penelitian pengembangan LKS matematika berbasis PBL pada materi bangun datar siswa kelas IV SD N 2 Air Lesing bahwa hasil dari keseluruhan komponen validasi tim ahli termasuk dalam kategori valid dengan rata-rata skor penilaian seluruh validator yaitu 3,19. Penelitian ini bertujuan untuk mengembangkan LKS berbasis problem based learning pada siswa kelas IV SD Negeri 2 Air Lesing dengan kurikulum 2013 serta menghasilkan LKS yang valid, praktis, dan memiliki efek potensial untuk digunakan dalam belajar. ![]()
