This study aims to determine the product development process for sequences and series based on Realistic Mathematics Education (RME). This development research uses a combination of the Plomp and Gravemeijer & Cobb development models. This research was carried out based on the results of a preliminary study where there were still many students who were constrained by learning mathematics and solving everyday math problems and there was still a lack of teachers making problem-based learning paths that were close to students' daily lives, especially in West Pasaman. In this study, validation tests were carried out by mathematicians, linguists and educational technologists as well as product feasibility tests by teachers and students. Data collection instruments were validation sheets, observations, interviews, questionnaires and field notes. Data analysis used is descriptive statistics and descriptive techniques. From the results of the analysis, the expert validation data was 0.77 with the criteria of "valid" and the Intraclass Correlation Coefficient (ICC) index was 0.54 in the moderate category. As for the teacher's book, the validation data was 0.75 in the "valid" category and the ICC index was 0.72 in the moderate category. Expert validation for student books is 0.77 in the "valid" category and the ICC index is 0.68 in the moderate category. Product feasibility test by students (small group) 80.91% with the "practical" category and large group feasibility test 82.71% with "practical" criteria.

The literature study and preliminary analysis conducted showed that students' critical thinking skills were still low. This study aims to determine the characteristics of Attention, Relevance, Confidence, Satisfaction (ARCS)-based learning tools that contain valid, practical, and effective HOTS questions to improve the critical thinking skills of class VIII students of SMP N 6 Padang Panjang. This research is a development research using the Plomp model. The learning tools developed are in the form of Learning Implementation Plans (RPP) and Student Activity Sheets (LKPD). The research subjects were students of class VIII SMP N 6 Padang Panjang. Data was collected through documentation, observation, interviews, questionnaires, and tests of critical thinking skills. RPP Validity Score: 3.28 and LKPD: 3.21 with a valid category. Practicality of RPP: 92.08% and LKPD: 87.35% with very practical category. The effectiveness of learning tools based on testing the average critical thinking skills of the experimental class was 81.93, control class was 76.63. Based on statistical tests, a significance value of 0.048 <0.05 was obtained, and based on the list of t distribution tables with (????????)=60 and a=0.05, 1.671. Because t_count= 2.108>1.671=t_(table) then H0 is rejected and accepts H1. Based on the test results, it can be concluded that the ARCS-based learning tools contain HOTS questions that meet valid, practical, and effective criteria to improve students' mathematical thinking skills.

Kurangnya keterampilan pemecahan masalah di kalangan siswa dibuktikan dengan kesulitan mereka dalam menangani masalah matematika secara efektif. Kurangnya akses terhadap materi pembelajaran yang mendukung memperparah masalah ini. Selain itu, integrasi teknologi yang kurang optimal dalam pendidikan matematika berkontribusi terhadap pelepasan siswa dari proses pembelajaran. sehingga diperlukan pendekatan atau model pedagogi yang mampu mengatasi tantangan-tantangan ini. Model yang diusulkan adalah Creative Problem Solving (CPS), yang dilengkapi dengan perangkat lunak G-Suite for Education. Penelitian ini bertujuan untuk meningkatkan kemampuan pemecahan masalah matematis peserta didik. Model penelitian ini mengikuti metodologi Plomp yang meliputi tahapan penyelidikan awal, pengembangan atau prototyping, dan penilaian. Kerangka pembelajaran yang dikembangkan meliputi pemahaman masalah, perencanaan solusi, implementasi, dan evaluasi. Temuan penelitian menunjukkan keefektifan model CPS berbantuan G-Suite, yang mencapai tingkat keberhasilan sebesar 84%. Selanjutnya tanggapan siswa terhadap model ini adalah positif. Kesimpulannya bahwa pemanfaatan Lembar Kerja Siswa (LKPD) berbasis model CPS dengan dukungan G-Suite meningkatkan kemampuan pemecahan masalah matematis siswa dalam ranah pendidikan matematika. The lack of problem solving skills among students is evidenced by their difficulty in dealing with mathematical problems effectively. Lack of access to supportive learning materials exacerbates this problem. In addition, less than optimal integration of technology in mathematics education contributes to student disengagement from the learning process. so a pedagogical approach or model is needed that is able to overcome these challenges. The proposed model is Creative Problem Solving (CPS), which is equipped with G-Suite for Education software. This research aims to improve students' mathematical problem solving abilities. This research model follows the Plomp methodology which includes stages of initial investigation, development or prototyping, and assessment. The learning framework developed includes problem understanding, solution planning, implementation and evaluation. Research findings demonstrate the effectiveness of the G-Suite-assisted CPS model, achieving a success rate of 84%. Furthermore, students' responses to this model were positive. The conclusion is that the use of Student Worksheets (LKPD) based on the CPS model with G-Suite support improves students' mathematical problem solving abilities in the realm of mathematics education.

Salah satu standar kemampuan matematika yang berperan besar bagi siswa adalah kemampuan pemecahan masalah. Namun dalam kenyataannya Kemampuan siswa dalam menyelesaikan masalah matematika masih kurang baik. Hal ini dikarenakan siswa kurang berlatih dalam menyelesaikan soal-soal yang memuat kemampuan pemecahan masalah dan soal-soal non rutin, pembelajaran di kelas masih berfokus kepada guru, secara umum, materi pembelajaran yang digunakan terbatas pada buku pelajaran. Oleh karena itu, e-modul berbasis Pembelajaran Berbasis Masalah (PBL) dikembangkan dengan tujuan untuk meningkatkan kemampuan siswa dalam memecahkan masalah. Prosedur pengembangan menggunakan model Plomp yang terdiri dari tiga fase, yaitu fase investigasi awal, fase pengembangan atau pembuatan prototipe serta fase penilaian. Subjek Uji coba adalah siswa Kelas VIII SMPN 1 Painan. Instrumen penelitian yang digunakan yaitu angket validitas dan angket praktikalitas. Uji validitas dilakukan oleh 3 orang ahli matematika, 1 orang ahli bahasa dan 1 orang ahli teknologi guruan. Uji praktikalitas dibatasi pada tahap Small group dengan 6 orang siswa. Penelitian menggunakan teknik deskriptif dan statistik deskriptif dalam analisis data. Selanjutnya, hasil penelitian menunjukkan bahwa e-modul berbais PBL sudah valid dengan skor 90,51% dan praktis digunakan dengan skor pada tahap small group 81,15% . Berdasarkan hasil penelitian disimpulkan bahwa e-modul berbasis PBL praktis dalam hal keterbacaan dan kejelasan materi, keterpakaian dan kemudahan penggunaan, daya tarik dan kesesuaian alokasi waktu serta praktis digunakan dalam meningkatkan kemampuan pemecahan masalah matematis siswa.One of the significant standards for students' mathematical abilities is problem-solving skills. However, in reality, students' mathematical problem-solving skills are still low. This is due to the need for more practice in solving problems that involve problem-solving skills and non-routine questions. Classroom learning is still teacher-focused, and instructional materials rely solely on textbooks. Therefore, an e-module based on Problem-Based Learning (PBL) has been developed to enhance students' problem-solving abilities. The development procedure follows the Plomp model, consisting of three phases: the initial investigation phase, the development or prototype creation phase, and the assessment phase. The trial subjects are eighth-grade students from SMPN 1 Painan. Research instruments used include validity questionnaires and practicality questionnaires. Validity testing involves three mathematics experts, one language expert, and one educational technology expert. Practicality testing is limited to the small group stage with six students. Research utilizes descriptive and descriptive statistical techniques in data analysis. The research results indicate that the PBL-based e-module is valid, with a score of 90.51%, and practical for use in the Small group stage, with a score of 81.15%. Based on the research findings, the PBL-based e-module is practical regarding readability and clarity of content, usability and ease of use, attractiveness and suitability of time allocation, and practical for enhancing students' mathematical problem-solving abilities.
