OpenStax Digital Instructional Materials For American Higher Education Development And Application Research

Since the 21 st century,maintaining continuous innovation in the field of information and communication technology has been a key strategy for countries to promote the construction of education informatization.With the continuous integration of education and information technology,various types of "Internet +education" have appeared in various types of education.Form,in which digital learning through the effective integration of information technology and curriculum,has completely changed the traditional teaching structure and the nature of education,to achieve a student-centered learning approach.The need for digital education resources has become increasingly prominent,and traditional paper textbooks are difficult To meet the educational needs of the digital learning era,digital textbooks have emerged.The development and application of digital textbooks in the U.S.higher education field has mushroomed in recent years,and has been effective in the publishing and development of digital textbooks,cutting-edge technologies,and teaching applications.It is of significance to promote the construction and application of digital teaching materials in China's higher education.This paper takes educational informationization and digital learning as the background of the times,and selects the model of the development and application of digital teaching materials in the American higher education stage-Rice University's OpenStax digital teaching material project as the research object.The realistic background and development of the development and application of OpenStax digital teaching materials.Explore the four aspects of model,technical tools,and teaching application strategies,and use the literature method,case method,and comparative method to comprehensively and objectively analyze the US OpenStax digital textbooks in order to find an effective path for the development and application of digital textbooks in the field of higher education in China..This article consists of five parts.The first part of the thesis analyzes the actual background of the development and application of OpenStax digital teachingmaterials in the United States.The United States is the pioneer country of open education resources movement based on Open Educational Resources(OER),OER It has stirred up a wave of high-quality education resources sharing in American research universities.The development of higher education informatization in the United States is facing great challenges and opportunities.Improving the "digital fluency" of teachers and students is one of the challenges that can be solved through technical means at present.U.S.colleges frequently change and expensive traditional paper textbooks are difficult to meet the needs of the current digital learning environment.The U.S.government encourages the development and application of digital textbooks in various forms.The second part explores the development model of the OpenStax digital teaching materials in the United States.Open sharing and copyright protection are the development concepts of the OpenStax digital teaching materials.The non-profit operating model is the basic prerequisite to ensure its open sharing.At the same time,a series of digital Quality assurance measures in the development and application of teaching materials to ensure the high quality of digital teaching materials.The third part explores a series of learning assistive technology tools and products developed by OpenStax digital textbooks based on the above-mentioned concept model,and has become an effective bridge between the ideal learning method and the practical teaching application.By building an online platform for digital education resources,Give the platform the ability to integrate resource publishing and multi-agent collaborative editing to achieve a series of functions such as modular presentation of resource content and flexible accessibility of the platform;and take OpenStax digital teaching materials as the content center,equipped with an intelligent tutor system and online job management Device to maximize the technical environment of OpenStax digital teaching materials to improve the effectiveness of teaching applications.The fourth part,from the perspective of teaching applications,analyzes the OpenStax digital teaching materials in an important way through the replacement of traditional paper textbooks,integrates teaching resources in multiple dimensions to support teachers' classroom teaching applications,and presents knowledge in a modular way to enhance teachers.Ability to organize information,and finally link digital textbooks with degree education to create a textbook-free degree.Landed in college classrooms through a series of methods,breaking the barriers of "build without use",and jointly achieving teacher professional development and learners from multiple dimensions The ultimate goal of synchronous improvement inacademic achievement.The fifth part,starting from the actual needs and background of the development and application of digital teaching materials for higher education in China,combined with the many experiences of Open Stax digital teaching materials in the United States,discusses the effective path of the development and application of digital teaching materials for higher education in China.Participate in the education digital publishing market,develop and design digital textbook peripheral products,improve the digital learning system of universities,inject cutting-edge technology in digital textbook development,and realize the deep integration of digital textbooks and teaching.
