This chapter was informative and interesting. I enjoyed reading the best practices and the research behind designing courses. I agree that the planning stage of course design is extremely important. In my experiences developing online courses, I spent hours planning the components of the course. In my first few years, I created a course map on paper before I started adding parts in the course. After twelve years of experiences, I can now do the course mapping and planning mostly in my head and making an outline so I can keep track of my progress. I use the Unit-Module-Topic Model and started using it before I knew it was a named model with research support. When I started building online courses, I had ideas for effective setup because I gathered insight while completing my Master's degree in the online format. The time consuming aspect for me was figuring the best presentation of science courses in the online learning environment, as science usually involves hands-on labs on campus. My solution was to develop labs that require common items from a grocery store, pet store, hardware store so the students could experience the hands-on labs at home. These days, there are lab kit supply companies that ship lab kits to students that contain most the materials needed to complete the labs at home. I think the main concept of designing and teaching online courses is to continuously update, modify, improve both the courses and teaching methods. The first online course I developed was before the popular course management systems, I had to upload files to a server. The course was basically set up as similar to a web page. I appreciate the course management systems with the tools and components available in the system. I found it interesting that this chapter emphasized the careful selection of content and delivery means. The means used to deliver content should be carefully chosen, and technology does not improve learning. Learning is enhanced by a well planned course that is set up effectively, and the content presented by the best possible method. In addition, the learning objectives are the focus, activities should support the learning objectives. You should never add technology just for the sake of having technology in use, you should consider the content you want to present and then determine the most effective way to present the information so that learners are interacting with the material and others.
