The purpose of this study is to analyze the needs of students and teachers in the development of contextual-based statistical material e-module materials for grade VIII students. This research uses qualitative descriptive method for initial analysis of product development by making junior high school or MTS math teacher in Pandeglang and MTs student Malnu Kadukaung as research subjects. Collection of data instruments using questionnaires via Google Forms. The study involved 15 teachers and 21 students. From this study btained the results that students still have difficulty solving problems or contextual problems even though at the time of learning the teacher has associated statistics with the concept of daily life, and also special teaching materials such as e-modules are not yet available so that students need alternative teaching materials in order to learn statistics to be easy and interesting. Whereas according to the teacher, teaching materials in the form of contextual-based e-modules need to be developed because teachers have not used e-modules as statistically specific teaching materials. So far, the teaching materials used by teachers have not been integrated with contextual approaches, as well as the teacher's positive response to the development of teaching materials in the form of contextual-based e-modules.

The 2013 curriculum requires students to master the cognitive domains from analysis to evaluation. The fact is not all students have the same cognitive development. Junior high school students, it turns out that students who think concretely, must see in real terms, so the learning approach used in this study has to lead students to be active in learning. One of active learning approach is the Realistic Mathematics Education (RME). This study is an experimental research. The goals of this study are: 1. Is the mathematical problem-solving abilities of students who used the RME approach better than students who used the scientific approac? 2. Determine whether there is an interaction between the learning approach and the mathematical initial ability (high, medium, low) on students' mathematical problem-solving abilities. The results showed: 1. The mathematical problem-solving abilities of students who used the RME approach was better than students who used the scientific approach; 2. There is no interaction between the learning approach and mathematical initial abilities (high, medium, low) on students' mathematical problem-solving abilities.

This research aims to determine the impact of flipped classroom learning models on students' problem-solving abilities. The research design used is a pseudo-experiment with a posttest-only control group. This study's population consisted of grade VIII students from SMP Serang for the 2021/2022 school year. Samples were determined using cluster random sampling techniques to obtain experimental and control classes. Data were gathered by administering a mathematical problem-solving ability test to students in the form of a description test at the end of the study. Based on posttest data, students' average mathematical problem-solving ability using a flipped classroom approach was 76.97 points. In comparison, students' average mathematical problem-solving ability using traditional learning was 64.33 points. The results of data analysis using a t-test with a 5% significance level revealed that the tcount is higher than ttable. This means that students who participate in flipped classroom learning have better problem-solving skills than students who use traditional learning models. As a result, flipped classroom model learning affects students' mathematical problem-solving abilities.
