Mathematics is often referred to as a field of knowledge developed through logical reasoning and is considered essential in everyday life, particularly in problem-solving. One effective way to apply problem-solving skills in mathematics education is through the use of word problems. This study aims to explore and analyze the various obstacles students encounter when solving mathematical word problems. The research employs a descriptive qualitative approach, with data collection methods including tests, interviews, and a project involving the construction of a staircase using standard units of length. The subjects of the study were four third-grade elementary school students in Batusangkar who had previously studied standard units of length. The findings reveal that students faced a range of difficulties, such as challenges in understanding the problems, failure to organize solution steps systematically, and limited comprehension of the concept of standard measurement units. Additionally, a lack of interest in learning was found to negatively impact students’ ability to solve word problems. Therefore, conceptual understanding and increased motivation to learn are crucial factors in enhancing students’ mathematical problem-solving abilities.

This research aims to determine the implementation of the Missouri Mathematics Project (MMP) learning model and the influence of the Missouri Mathematics Project (MMP) learning model on the concept understanding ability of class II MI Miftahul Huda students in the 2024/2025 academic year. The method used in this research is an experimental method with a quasi-experimental type. The design in this research is a nonequivalent control group design. This research design involved two classes, the experimental class, namely class II A using the missouri mathematics project learning model and control class II C using the conventional learning model. Data collection techniques use the results of concept understanding tests. Based on the results of research on the Independent Sample T-test which shows that the significance (2-tailed) is 0.000 < 0.05, which means less than 0.05, so H0 is rejected and Ha is accepted, which means there is an influence of the missouri mathematics project learning model on understanding ability. MI Miftahul Huda class II flat shape concept.

This study aims to identify and analyze language errors in the Discrete Mathematics book, which may affect the clarity and comprehension of the presented material. The analysis focuses on capitalization, punctuation, word usage, and sentence structure. The research employs a qualitative descriptive method with a literature study approach. Data were collected through in-depth reading and recording of linguistic errors found in the book's text. The results indicate that errors such as improper capitalization, punctuation mistakes, inaccurate word choices, and ineffective sentence structures can hinder the understanding of discrete mathematics concepts. Therefore, linguistic improvements are necessary to enhance the book's effectiveness and quality as a teaching material. These revisions are also expected to increase the book’s academic credibility as a reference for students and scholars.
