Development of Project-Based E-Module to Facilitate Student's Mathematics Collaboration and Communication in Boarding School

Technological advances in mathematics education emphasise the importance of students having good mathematical collaboration and communication skills. However, the use of electronic-based teaching devices that support this is still rarely found, especially in Islamic boarding schools. This research aims to develop teaching materials in the form of project-based e-modules to facilitate junior high school students' mathematical collaboration and communication skills for use in mathematics learning. This type of research is developed using the Research and Development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The subjects of this research were students in class VIII-A Al-Izzah IIBS Batu in the Islamic boarding school curriculum. Data collection techniques include unstructured observation and interviews. Data collection instruments used expert validation sheets, e-module reflection sheets, and post-tests. The development of this learning media has been proven to be valid and practical, with an average percentage of validity of 95.86% and practicality of 93.33%. Apart from that, Project-based e-modules can support students in communicating well so that collaboration is formed in teams that can respect differences of opinion and be responsible for their contributions. Based on the results obtained, the project-based e-module is valid and practical in facilitating Islamic boarding school students' mathematical collaboration and communication skills in mathematics learning statistics material.
