N/DUnda García, Gabriela2023-11-252023-11-252014https://repositorio.puce.edu.ec/handle/123456789/23217The purpose of this thesis is to analyze and edit a science book so that it fits the reality of the students using it in the classroom. The analysis shows that teaching material does not always coincide with the objectives of specific students and cultures. The thesis also seeks to demonstrate to teachers that teaching materials should be used carefully because they may need to be adapted in order to work successfully. The science book will be considered as a case study because it is an example of how teaching material fails to match the needs of students and teachers. It is hoped that this thesis will provide an alternative to teachers using the same book in their science classes in Ecuador.enOpenAccessTHEORETICALCONCEPTUAL FRAMEWORKTEACHING MATERIALSINTERLANGUAGEmasterThesis
