Explanation of representation levels or known as multiple representations in chemistry learning is very important to provide students with a complete understanding of the material concept being studied. One of the chemistry subject matters that requires multiple representation explanations is the colligative properties of solutions. The research aims to develop teaching materials of mobile apps based on multiple representation with learning cycle 7e model on the material colligative properties of solutions which is feasible as a material resource. Research which is conducted the research development by using the 4D model Thiagarajan, but research is limited only in three stages namely the define, design, and develop stages, then continued with the revision of the final product of teaching materials. The validation test of teaching materials was carried out by 2 chemistry lecturers and 1 chemistry teacher. Aspects of validation include assessing aspects of content, construct, language, media, and conformity with the learning cycle 7e syntax. The readability test was carried out by 20 students of XII class IPA SMA Negeri 1 Tumpang. Aspects of readability test include assessment of appearance, presentation material, and benefits. The data obtained were analyzed by percentage and interpreted to determine the feasibility of developed teaching material. The results of the validation test obtained a percentage of 84% (very feasible) and a readability test of 92% (very feasible). This shows that the multiple representation-based mobile apps teaching materials with the 7e learning cycle model on the colligative properties of the solutions that have been developed are very feasible to be used as teaching materials.]]></p></abstract>

La explicación de los niveles de representación o conocidas como representaciones múltiples en el aprendizaje de la química es muy importante para proporcionar a los estudiantes una comprensión completa del concepto de material que se estudia. Uno de los temas de la química que requiere múltiples explicaciones de representación son las propiedades coligativas de las soluciones. La investigación tiene como objetivo desarrollar materiales didácticos de aplicaciones móviles basados en representación múltiple con modelo de ciclo de aprendizaje 7e sobre las propiedades materiales coligativas de soluciones que es factible como recurso material. Investigación que se lleva a cabo el desarrollo de la investigación utilizando el modelo 4D Thiagarajan, pero la investigación se limita solo a tres etapas, a saber, las etapas de definición, diseño y desarrollo, y luego continúa con la revisión del producto final de los materiales didácticos. La prueba de validación de materiales didácticos fue realizada por 2 profesores de química y 1 profesor de química. Los aspectos de la validación incluyen la evaluación de aspectos del contenido, la construcción, el idioma, los medios y la conformidad con la sintaxis del ciclo de aprendizaje 7e. La prueba de legibilidad fue realizada por 20 estudiantes de la clase XII IPA SMA Negeri 1 Tumpang. Los aspectos de la prueba de legibilidad incluyen la evaluación de la apariencia, el material de presentación y los beneficios. Los datos obtenidos fueron analizados por porcentaje e interpretados para determinar la factibilidad del material didáctico desarrollado. Los resultados de la prueba de validación obtuvieron un porcentaje del 84% (muy factible) y una prueba de legibilidad del 92% (muy factible). Esto muestra que los materiales didácticos de múltiples aplicaciones móviles basadas en representaciones con el modelo de ciclo de aprendizaje 7e sobre las propiedades coligativas de las soluciones que se han desarrollado son muy factibles para ser utilizados como materiales didácticos.]]></p></abstract>
