Pengaruh Model Pembelajaran Problem Based (PBL) Dengan Menggunakan Lembar Kerja Siswa  (LKS) Terhadap Pembelajaran Sains Anak Kesulitan Belajar. 

The Influence of Problem Based Learning (PBL) Using Student Working Sheets (LKS) on The Science Learning Activity of Children with Learning Difficulty

Anak kesulitan belajar membutuhkan model pembelajaran Problem Based Learning (PBL) dengan media Lembar Kerja Siswa (LKS) untuk membantu meningkatkan kemampuan dalam memahami sains pembelajaran. Hal tersebut  mendukung keberhasilan akademis dan merupakan sarana bagi guru untuk mengukur kemajuan belajar sains siswa. Penelitian  ini bertujuan untuk mengukur pengaruh model penerapan pembelajaran Problem Based Learning (PBL) dan penggunaan media Lembar Kerja Siswa (LKS) terhadap pemaahaman pembelajaran sains anak kesulitan belajar. Desain penelitian yang digunakan yaitu Pre-eksperimen Pretest – Memposting. Subjek dalam penelitian ini adalah 6 anak kesulitan belajar kelas 4 SD usia 10-11. Pengumpulan data dengan menggunakan teknik tes. Teknik analisis data yang digunakan yaitu Tes Pasangan Matematika Wilcoxon. Hasil penelitian menunjukkan adanya peningkatan nilai kemampuan pemahaman anak kesulitan belajar dalam pembelajaran sains. Nilai pretest, diperoleh nilai rata-rata 55 dan nilai posttest diperoleh nilai rata-rata 84,1. Hasil analisis menggunakan rumus wilcoxon Zhitung diperoleh nilai Z= 2,214.  Maka dapat disimpulkan bahwa adanya pengaruh dari  penerapan model pembelajaran Problem Based Learning (PBL)  dan penggunaan media Lembar Kerja Siswa (LKS) terhadap  pemaahaman sains pembelajaran anak kesulitan belajar. Dalam  pelaksanaan LKS siswa diarahkan menemukan konsep dengan  melengkapi contoh soal di lks dengan diskusi kelompok, menguraikan hasil diskusi, dan siswa mengerjakan soal di lks secara individu.

Children with learning difficulties need a Problem Based Learning (PBL) learning model using Student Worksheets (LKS) to help improve their ability to understand the science of learning. It  supports academic success and is a means for teachers to measure students' science learning progress. This  research aims to measure the influence of the Problem Based Learning (PBL) learning model and the use of Student Worksheets (LKS) on the understanding of science learning for children with learning difficulties. The research design used was Pre-experiment Pretest – Post. The subjects in this study were 6 children with learning difficulties in 4th grade elementary school aged 10-11. Data collection using test techniques. The data analysis technique used is the Wilcoxon Mathematical Pair Test. The results of the study showed an increase in the comprehension ability scores of children with learning difficulties in science learning. The pretest score obtained an average score of 55 and the posttest score obtained an average score of 84.1. The results of the analysis using the Wilcoxon Zcount formula obtained a Z value = 2.214. So it can be concluded that there is an influence from  the application of the Problem Based Learning (PBL) learning model  and the use of Student Worksheet (LKS) media on  the learning science understanding of children with learning difficulties. In  implementing the worksheet, students are directed to discover concepts by  completing example questions in the worksheet with group discussions, elaborating on the results of the discussion, and students work on the questions in the worksheet individually.
