 In terms of research, a lot of the time we use textbook, and textbook is excellent, but oftentimes it doesn't cover all the material we would like to cover in one course. And so, as an instructor, we often choose the book chapters from several books, and to minimize the financial burden for students, we seek support from our copyright expert and to secure copyright from the book chapters that we plan to use for our class, and then able to post those book chapters on the Moodle side, so students can easily access them, and they'll purchase several books for one class. Another component is that one of the classes I'm teaching this semester focus on assessment and documentation. In this course, we do need to discuss different assessment tools that we use in my field. Most of those assessment tool isn't free, and even it's for educational purpose. But for one course, if we need to secure all the copyright for all of the assessment tools, that would become very troublesome for the department, and it would be difficult for the students. Also, we were able to teach students a diverse range of assessment tools regardless they are copyrighted or they are not. We certainly do not want to limit students' education to only have access to free assessment tools, right? We want them to have a broad knowledge about what's available there, and so they were able to do an informed decision in the future when they become a practitioner that can choose whether they want to use a free assessment tool because it's better for their clients, or they want to purchase a specific assessment tool because it's better to understand their client's condition. A lot of time in our research that we follow specific theoretical model, and if we want to include those models, especially their graph, in our manuscripts, oftentimes the publisher will ask whether we have copyright to put those figures in our manuscript. If those figures have been published in journal articles before, usually the copyright isn't such an issue, but if the figures are included in a certain book or the image is from a book, then we often need to work with the publisher to secure copyright. Beyond that, most likely to relate to fair use is the assessment tool that we will be using in research that whether we are able to purchase the assessment tool or if we are able to just use them if they have been published in a research article. We don't want to limit students' learning to just free material, and we want students to be able to access the information that's most current because in healthcare field, there are a lot of new information coming every day. There are new interventions that are available, there are new assessment tools that are available for practitioners to use. In the education setting, we do hope to support students, allow them to learn where to find those information, and we also want to educate them about copyright issues.
