Abstract

The study aims to produce e-module teaching materials based on Discovery Learning, supported by GeoGebra and LiveWorksheets, as well as to determine whether this e-module is valid, practical, and has a potential effect on students' problem-solving abilities. The research method used is Research and Development (R&D) with an ADDIE design. The research process consists of five stages: (1) Analysis (analysis of material needs, material analysis, and analysis of student characteristics); (2) Design (design or product framework to be made as an initial overview); (3) Development (development of the e-module and preparation of instruments to be used for valid, practical, and effective assessments); (4) Implementation (product review to be developed in classroom learning); (5) Evaluation (the product will be revised based on feedback given by the students to ensure the quality of the developed product is appropriate and adequate). The e-module learning materials were given to class X students of Senior High School. The results of the expert material validation obtained a percentage evaluation of 88%, indicating valid criteria. The test results showed that this e-module received a positive response from the students with an average percentage evaluation of 85%, categorizing it as highly effective. The material validation resulted in an 88% evaluation percentage, indicating valid criteria. The students' validation results obtained an 85% assessment percentage, also indicating valid criteria. The development of this module is worthy and suitable for use in schools by teachers to enhance students' conceptual understanding of quadratic equations and quadratic functions. Additionally, the module can develop critical thinking and problem-solving skills, which are crucial in 21st-century education.

Abstract

Abstrak Tujuan penelitian ini adalah mengembangkan instrumen numerasi sub domain barisan dan deret tingkat SMA dilakukan di kelas XI SMAN 2 Bayah, Kabupaten Lebak. Penelitian yang dilakukan adalah (R&D) dengan model pengembangan model Wilson dan model Oriondo dan Antonio terdiri atas tiga tahap yaitu (1) desain instrumen; (2) uji coba instrumen; (3) perakitan instrumen. Hasil penelitian ini yaitu (1) Instrumen pengembangan numerasi merupakan instrumen yang valid dengan kriteria tinggi untuk semua butir soal dan reliabel (2) Instrumen numerasi memiliki daya pembeda yang baik untuk semua butir soal  (3) Instrumen numerasi memiliki indeks kesukaran mudah untuk butir soal no 1, sedang untuk butir soal nomor 2,3 dan 4 serta sukar untuk butir soal nomor 5. Instrumen penelitian pengembangan sub domain barisan dan deret layak dan dapat digunakan untuk proses pembelajaran mengembangkan kemampuan numerasi siswa.  Kata kunci: Pengembangan Instrumen Tes, Barisan dan Deret, Numerasi Abstract The purpose of this research is to develop a sub-domain numbering instrument of row and row of high school level carried out in the XI class of SMAN 2 Bayah, Lebak district. The research carried out was (R&D) with the development model of the Wilson model and the Oriondo and Antonio model consisting of three stages: (1) instrument design; (2) instrument testing; (3) instrument assembly. The results of this study are: (1) The numeration development instrument is a valid instrument with a high criterion for all the elements and reliable (2) the numeration instrument has a good differentiating power for all those elements (3) the numbering instrument has an easy difficulty index for the element number 1, the average for the elements number 2,3 and 4 as well as difficult for the items number 5. Research development tools sub-domain rows and series are qualified and can be used for the learning process to develop student numeration skills Keywords: development of test instruments, Row and Series, Numeracy
