Abstract


Tujuan dari penelitian ini adalah untuk menganalisis keterampilan menjelaskan dan kemampuan pemecahan masalah pada konsep ekosistem melalui implementasi model Jigsaw. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Instrumen penelitian yang digunakan adalah task dan rubric, tes essay dan lembar observasi. Teknik pengolahan data yang digunakan adalah uji normalitas, uji Z dan uji N-Gain. Berdasarkan hasil analisis data uji t satu perlakuan diperoleh nilai statistik uji hipotesis memperoleh nilai t = 63,997 dengan Sig. 0,000 < 0,05 artinya terdapat pengaruh penerapan model problem based learning terhadap keterampilan menjelaskan pada materi ekosistem di kelas VII. Hasil analisis uji hipotesis menunjukkan nilai t = 40,022 dengan dengan Sig. 0,000 > 0,05 artinya terdapat pengaruh penerapan model jigsaw terhadap kemampuan pemecahan masalah pada materi ekosistem di kelas VII. Berdasarkan hasil analisis nilai statistik uji N-Gain memperoleh nilai t = 54,826 dengan Sig. 0,000 < 0,05 artinya terdapat tingkat pengaruh penerapan model jigsaw terhadap keterampilan menjelaskan dan kemampuan pemecahan masalah pada materi ekosistem di kelas VII. Kesimpulan dalam penelitian ini adalah terdapat pengaruh penerapan model jigsaw terhadap keterampilan menjelaskan dan kemampuan pemecahan masalah pada materi ekosistem di kelas VII.

 

The purpose of this study is to analyze the students' skill of explaining and the ability to solve problems in the concept of ecosystems through the implementation of the Jigsaw model. The method used in this research is the experimental method. The research instruments used were task and rubric, essay tests, and observation sheets. Data processing techniques used were normality test, Z test, and N-Gain test. Based on the analysis of one treatment, t-test data obtained the statistical value of the hypothesis test obtained a value of t = 63.997 with Sig. 0,000 <0.05 means that there is an influence of the application of the problem-based learning model to the explaining skills in the ecosystem material in class VII. The results of the hypothesis test analysis showed the value of t = 40.022 with Sig. 0,000> 0.05 means that there is an effect of the application of the jigsaw model on the ability to solve problems in ecosystem material in class VII. Based on the results of the analysis of the statistical value of the N-Gain test, obtained t value = 54.826 with Sig. 0,000 <0.05 means that there is a level of influence of the application of the jigsaw model to the skills of explaining and the ability to solve problems in ecosystem material in class VII. The conclusion in this study is that there is an effect of the application of the jigsaw model to the skills of explaining and the ability to solve problems in ecosystem material in class VII.
