This study aims to determine the increase in the ability to understand concepts in terms of self-efficacy between students who receive probing prompting learning models and students who receive conventional learning models. Conceptual understanding is a situation where students find and prove a concept themselves without the memorization process. The research method used Quasi Experimental with a nonequivalent control group design with a research sample consisting of two classes. The results of the study showed that the pretest results obtained an average value of 20.00 and the average pretest results 45.67, while the posttest results showed that the average value in the experimental class was 79.67 while the average value in the control class was 63.00. Based on the average posttest score, both groups experienced a significant increase, especially in the experimental class which experienced a very significant change. The resultshow that mathematical concept understanding ability of students who received learning using the probing prompting model in terms of self-efficacy was better than the mathematical concept understanding ability of students who used conventional learning models. The conclusions from the results that is there is an increase in the mathematical concept understanding ability of students using the Probing Prompting learning model

This research aims to find out the validity of the development and the practicality of using an Android-based interactive mathematics E-Module in statistics material for class Design, Development and Dissemination. Product trials were carried out on 23 class X Akl2 students and mathematics subject teachers. The results of the research were that the validation stage consisted of three validators, namely, one language expert, one material expert and one media expert with the total average percentage of the three validators being 87.18% in the "very valid" category. At the product testing stage to determine the practicality of using the mathematics E-Module using student response tests and teacher responses, the average score was 85.72% in the "Very Practical" category. So it can be concluded that the use of the Android-based interactive mathematics E-Module in the statistics material for class X students that has been developed is valid and practical so it is suitable for use in the learning process.

Lastri (NIM: 407190011). 2023. Peningkatan Kemampuan Berfikir Kreatif Matematis Siswa Melalui Model Pembelajaran Comprehensive Mathematics Instruction (CMI).

Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan berpikir kreatif matematis siswa SMAN 1 Cihara melalui model pembelajaran Comprehensive Mathematics Instruction (CMI). Metode yang digunakan dalam penelitian ini merupakan eksperimen. Populasi dalam penelitian ini adalah siswa SMAN 1 Cihara. Adapun sampel dalam penelitian ini adalah siswa kelas X 2 sebagai kelas eksperimen dan kelas X 1 sebagai kelas kontrol. Instrumen yang digunakan peneliti adalah tes kemampuan berpikir kreatif matematika siswa dengan jumlah soal sebanyak 5 soal dengan bentuk uraian, dimana sebelumnya soal tersebut sudah dilakukan uji validitas, reliabilitas, indeks kesukaran dan daya pembeda serta di uji cobakan terlebih dahulu dan soal tersebut dinyatakan layak digunakan. Analisis data yang digunakan yaitu uji perbedaan dua rerata dan Gain Score yang sebelumnya dilakukan prasyarat uji normalitas dan homogenitas. Setelah peneliti mengadakan penelitian dengan menggunakan model pembelajaran berdasarkan paparan data, temuan peneliti, dan pembahasan yang telah diuraikan, maka dapat disimpulkan bahwa terdapat peningkatan kemampuan berpikir kreatif matematis siswa melalui model pembelajaran Comprehensive Mathematics Instruction (CMI) pada materi eksponen di SMAN 1 Cihara.
