Abstract

The test instrument is one aspect of the learning process that is used to produce learning outcomes or the level of knowledge of students. The research method used in this research is descriptive quantitative research. The population in this study were all students of class VIII SMP Negeri 1 PGRI Batanghari which consisted of 5 classes, with research samples namely class VIII B and class VIII A, the results of this study showed content validity based on experts with an average V index of more than 0,3 then for empirical validity 14 of 15 are declared valid with an average result of more than 0.3, then the reliability test shows the results of 0.740 > 0.6 so it can be said that a valid and reliable mathematical communication ability test is used to measure communication skills mathematics relational materials and functions

Abstract

This research aims to analyze the validity of the content of the project assessment instrument for Islamic religious learning and character in the independent curriculum based on the Aiken validity index so that the instrument can measure what it will measure. The research method used is a quantitative descriptive method based on content validity results which are calculated using the Aiken V formula. Content validity data was obtained from 5 experts, namely 2 Islamic religious education experts and 3 evaluation experts. The content validity test in this study used 4 assessment criteria, namely Very Appropriate (VA), Appropriate (A), Not Appropriate (NA), Very Inappropriate (VI). The Project Assessment instrument for learning Islamic religious education and morals resulted in 15 indicators being declared valid with an average Aiken index above 0.873. The project assessment is declared to be suitable for measuring what it wants to measure, and can be used to measure the results of Islamic religious education and character learning project assignments in the independent curriculum.

Abstract

Penelitian ini dilatar belakangi rendahnya kemampuan komunikasi matematis peserta didik. Hal ini dapat disebabkan oleh beberapa faktor diantaranya adalah kebanyakan guru matematika hanya menekankan pada materi semata dan lebih banyak menjalin komunikasi satu arah dengan peserta didik (teacher center) sehingga peserta didik kurang aktif dalam menyampaikan ide–idenya, mengingat bahwa pentingnya kemampuan komunikasi matematis maka perlu dikembangkan model pembelajaran yang erat hubunganya dengan kemampuan komunikasi matematis. Model tersebut diantaranya adalah model pembelajaran tipe Talking Chips bertujuan untuk mengetahui Pengaruh Model Pembelajaran Kooperatif Tipe Talking Chips terhadap Kemampuan Komunikasi Matematis Peserta Didik Kelas VIII SMP PGRI 1 Batanghari. Jenis Penelitian ini adalah penelitian eksperimen dengan tiga kelompok sampel yaitu satu kelompok eksperimen dan satu kelompok kontrol. Kelompok eksperimen yang pertama memperoleh perlakuan dengan menggunakan model pembelajaran kooperatif tipe Talking Chips, sedangkan untuk kelompok kontrol mendapat perlakuan dengan pembelajaran konvensional yaitu ceramah. Untuk memberoleh data hasil penelitian digunakan instrumen berupa tes kemampuan komunikasi matematis, dokumentasi dan pedoman wawancara. Subyek penelitian adalah peserta didik kelas VIII SMP PGRI 1 Batanghari Berdasarkan analisis variansi satu jalan terdapat Pengaruh Model Pembelanjaran Talking Chips Terhadap Kemampuan Komunikasi Matematis Peserta Didik Kelas VIII PGRI 1 Batanghari. Terdapat pengaruh yang signifikan model pembelajaran Talking Chips terhadap kemampuan komunikasi matematis dibandingkan dengan menggunakan Konvensional.
