Abstract

Most classes in Indonesia are heterogeneous classes, which must be a challenge for educators in implementing this independent curriculum. Therefore, this study aims to describe the probematics of educators in implementing the independent curriculum. This type of research is descriptive qualitative with the subject of 16 educators at the secondary school level in Jember Regency. The instrument used is a questionnaire collected using the questionnaire method with google form media which contains 17 questions. Based on the results of the analysis, it was found that there were problems in implementing the independent curriculum, namely 1) Lack of training on the independent curriculum. 2) Difficulty formulating the flow of learning objectives. 3) Knowing the needs of individual students. 4) Carrying out assessments.

Abstract

.The thinking process is crucial in identifying students' challenges in formulating logical arguments,particularly when proving geometric concepts such as Ceva's Theorem. This study investigates the cognitive processes of students with high and medium mathematical ability to solve proof problems related to Ceva's Theorem.Adopting a qualitative approach, the research employed a case study design, utilising data collection techniques including tests, interviews, observations, documentation, and triangulation.The research subjects comprised two undergraduate students of Mathematics Education, representing a medium and high mathematical ability category. The research findings revealed that students with high mathematical abilityprogressedthrough assimilation, accommodation, and equilibrium stages in proving Ceva's Theorem. In contrast, students with moderate mathematical ability experienced the disequilibrium phase first beforeadvancing to assimilation, accommodation, and equilibrium. The fundamental difference between these two groups lies in their ability to identify the question posed in the problem andcorrectly identify the theorem to be proved.This research provides valuable insights into the cognitive processes involved in mathematical proof, offering an in-depth understanding of how students approach the proof of Ceva's Theorem.

Abstract

Tujuan penelitian ini adalah menghasilkan modul elektronik berbasis GeoGebra Book pada topik persamaan garis lurus yang berfungsi untuk melatih literasi digital siswa yang terkategori valid dan praktis. Penelitian ini tergolong sebagai penelitian pengembangan (R&D) menggunakan model 4-D, namun terbatas sampai tahap pengembangan (develop) karena kendala waktu. Uji coba dilakukan pada siswa kelas VII pada SMPN 1 Panti dan MTs At Taqwa Bondowoso yang masing-masing diambil 1 kelas. Instrumen penelitian mencakup lembar validasi dari ahli media dan ahli materi, serta angket respon siswa. Hasil analisis menunjukkan bahwa pengembangan modul elektronik berbasis GeoGebra Book pada materi persamaan garis lurus memiliki tingkat validitas sangat valid dengan prosentase 95% dan tingkat kepraktisan sangat praktis dengan prosentase sebesar 90,91%. Berdasarkan hasil temuan tersebut, maka modul layak diuji lebih lanjut untuk menilai efektivitasnya dalam meningkatkan kemampuan literasi digital siswa.   Kata kunci: Modul Elektronik, GeoGebra Book,Persamaan Garis Lurus, Literasi Digital. Abstract: The purpose of this study is to develop an electronic module based on GeoGebra Book on the topic of linear equations to train students’ digital literacy skills, categorized as valid and practical. This research is a development study using the 4-D model, but it was limited to the development (develop) stage. The trial subjects were seventh-grade students from SMPN 1 Panti and MTs At-Taqwa Bondowoso, with one class selected from each school. The research instruments consisted of validation sheets for media and material experts, as well as student response questionnaires. The results of the data analysis showed that the electronic module based on GeoGebra Book on the topic of linear equations was categorized as very valid with an average score of 3.87 and very practical with an average student response score of 4.56. Based on these results, the module can be tested further to determine its effectiveness in improving students’ digital literacy skills. Keywords: Electronic Module, GeoGebra Book, Linear Equations, Digital Literacy
