This study aims to produce Student Worksheets using the Realistic Mathematics Education approach to build understanding of mathematical concepts in grade IV of Elementary School; This study is a Research and Development (R&D) research using a 4-D model. Validation is carried out by material experts, design experts and linguists. The developed were given scores and responses by 4 public elementary school teachers in Bengkulu City. Data analysis techniques used descriptive statistical analysis of the results of expert validation and teacher responses as well as qualitative descriptive analysis of comments from expert validation and teacher responses.. The results of the validity test of the mathematics that have been developed with the results of the material experts are 88.89 with a very valid category, the design expert validation is 94 with the very valid category, the validation of the linguist 90 is very valid and the teacher's response is 87.66 with the very category. valid as the final product of development and limited trial results to get an average value of 83.4 with completeness of 88.89%.

This study aims to determine the effect of guided inquiry model on student learning outcomes in Mathematics learning in grade V SD Gugus XII Kota Bengkulu. This type of research is a quasi-experimental research with the design of the study of the matching only pretest-posttest control group design. The population in this study is all students of class V SD group XII consisting of 5 elementary schools. Based on the homogeneity test results, the sample in this study were the students of grade V SDN 99 as the experimental class and the students of class V SDN 81 as the control class. The research instrument used is a matter of objective test consisting of 20 items. Data analysis used is descriptive analysis, prerequisite test and inferential analysis that is t-test. Based on data analysis of research results, obtained the average value of posttest result of experimental class using guided inquiry model that is 78,120 and control class using conventional learning that is 62,789. T-test of both sample classes with significance level? = 0.05, obtained count = 4,730 whereas ttable = 2,000, tcount> ttable so that H0 is rejected and Ha accepted. The increase of study result percentage in experiment class is higher than control class that is 83.36% in experimental class and control class 33.98%. Thus it can be concluded there is a significant effect of student learning outcomes that follow the learning using guided inquiry model.

This study aims to produce mathematics teaching materials using the Realistic Mathematics Education (RME) approach to foster mathematical literacy skills in fourth grade elementary school students that are feasible and effective to use. This research method is the Research and Development (R&D) method the modifed 4D model. However, this research is only at the development stage, because the COVID-19 situation has not improved. Validation is carried out by material, design, and linguist experts. The teaching materials developed were graded by 3 teachers of elementary school in north Bengkulu and tested on a limited basis in 2 elementary schools. The data analysis technique used descriptive qualitative and quantitative analysis. The results of expert validation were tested with an interrater reliability test to see the agreement between raters. This research produces RME-based mathematics teaching materials to foster mathematical literacy skills on the circumference and area of flat shapes in fourth grade elementary school students. The results of the validation of material experts get the score of 88.9 in the very good category, linguists get the score of 87.7 in the very good category, design experts get the score of 86.6 in the very good category, and get comments that the depth of the description is in accordance with the level of student development, the language used is communicative, fosters a sense of fun and stimulates students to answer questions, the overall illustrations and letters used are simple, harmonious and attractive. The teacher's response got an average score of 91.3 with a very good category. The results of the limited trial got an average score of 87.7 with a very good category. The product of developing mathematics teaching materials based on Realistic Mathematics Education to foster mathematical literacy skills is very good for use by fourth grade elementary school students.

This study aims to produce mathematics teaching materials using the Realistic Mathematics Education (RME) approach to train the mathematical connection skills to fourth grade elementary school students. This research is a Research and Development (R&D) research by modifying the ADDIE model. This research was only carried out at the development stage, while the implementation and evaluation stages could not be carried out due to the COVID-19 pandemic. Validation is carried out by material, linguists and product design experts. The teaching materials developed were graded and responded by 3 teachers from public elementary schools in North Bengkulu. The data analysis technique used descriptive statistical analysis on the results of expert validation assessments and teacher responses and qualitative descriptive analysis on comments from expert validation and teacher responses. This research produces a product of teaching materials based on Realistic Mathematics Education (RME) to train students' mathematical connection skills in the material of measuring angles in grade IV Elementary School. This research produces teaching material products with an average material expert validation assessment of 90 with a very good category, an average linguist validation of 88.88 in a very good category, an average product design expert validation of 96.67 with a very good category. good, and get a response that the depth of the material description uses a real context according to the level of student development, in terms of the language in the teaching materials according to the level of development of the student's age, the overall illustrations and letters used are simple (communicative), harmonious and create an attraction for students to learn RME based math module. The teacher's response got an average score of 90.67 with a very good category. So it can be concluded that the product of developing mathematics teaching materials based on Realistic Mathematics Education is very good to be used by fourth grade elementary school students.Keywords: Teaching Materials, Development, Realistic Mathematics Education, Mathematics connection.
