This textbook considers and addresses the design of online learning objects, electronic textbooks, short courses, long courses, MOOC courses, and other types of contents for open sharing. It also considers the design of online mediated communities to enhance such learning. The “openness” may be open-access, and/or it may even be open-source. The learning may range from self-directed and automated to AI robot-led to instructor-led.
 The main concept of this work is that design learning for open sharing, requires different considerations than when designing for closed and proprietary contexts. Open sharing of learning contents requires a different sense of laws (intellectual property, learner privacy, pedagogical strategies, technologies, media, and others). It requires different considerations of learner diversity and inclusion. It requires geographical, cultural, and linguistic considerations that are not as present in more localized designs. The open sharing aspect also has effects on learner performance tracking (assessments) and learner feedback.
 This textbook targets students, both undergraduate and graduate in computer science, education and other related fields. Also, professionals in this field managing online systems would find this book helpful.
