This work describes several tools for measuring textbook contents, their particularities, and benefits indicated by different authors, the permanence of the book as a teaching resource within the classroom, in the life of the teacher and the student. As well as explaining how the subject of Probability and Statistics is taught in engineering careers at a higher level of education. The application of the Delphi Method allows developing a tool to measure the content of Probability and Statistics textbooks, employing ten proposed items. The usefulness of the methodology is demonstrated by ensuring the reliability of the tool, obtaining quantitative and qualitative information. The method is developed in stages for better understanding, and expert judgement is used, despite sometimes being ignored. Finally, an alternative validation in instrument design is proposed analytically and reliably.","PeriodicalId":311303,"journal":{"name":"Revista de Educación Técnica","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126895761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
