The basic components above are the width, the height, and the source URL. When you embed media (like from YouTube, for example), the embed code looks like this: In this case, an easy option is to create your own using a variation of code with iframe attributes. ![]() jpg or image), what if you want to embed the tool itself into a page? How can you insert an interactive tool or webpage if you don't have the actual embed code? While Desmos gives embed code for a graph that is saved and created (as a static. We've posted previously about the magic of embed code, but we had a question this week from one of our school technology coordinators about embedding a graphing calculator tool ( Desmos) into an assessment in Schoology, our LMS. This entry was posted in Desmos, Graphing, Math Education, Mathematics and tagged Activities, Blackboard, desmos, graphing, iframes, Interactive, math education by Keith Jones. (If you are looking for the “Embed Media” button and do not see it, be sure you are viewing the full formatting menu by clicking the “Show More” button at the right end.) Blackboard’s “Embed Media” button in the (extended) formatting menu allows you to add iframes without knowing anything about HTML, but I show in the video how (if you’re willing to look at the raw HTML) you can make changes to the iframe attributes, such as making the width of the frame a percentage of total page width instead of fixed, that the Blackboard interface itself does not support. Iframes are just HTML’s way of embedding one page within another. While I demonstrate embedding the activity in a Blackboard page, this can be done in any page that supports iframes. But you’ll need your own account to save graphs on the site. ![]() You can even share graphs without being logged in. You can also include basic Desmos graphs without creating an activity, and you can even do this without an account if you are sharing a graph you found online instead of your own. They can even submit work to your class without an account. They would only need an account if they want to be able access their own previous work after leaving and returning. ![]() Do I Need an Account? Do My Students?Īs an instructor, you will want to have a Desmos account to manage collections of helpful activities, create links for your students to access them, and create your own activities if you like but students do not need to have their own accounts to access the demonstrations. However, you can build simple activities without scripting, just by relying on the power of the underlying graph.ĭesmos Activities are quite intuitive and natural to build, but it is worth exploring a few different activities to get a sense for the design philosophy before making your own - in short, you probably don’t want too much going on in a single screen, and think about building your activity as a sequence of screens. ![]() The scripting is natural enough, and the documentation is good enough, that (I believe) one does not really need programming experience to use it. This allows, for example, a student to enter a function in one component, have a second component graph that function, and a third component display interesting results from the graph. Components can talk to each other through a simple and straightforward scripting layer which fortunately is well-documented. An Activity is a sequence of screens, with each screen consisting of a small collection of components (such as graphs, notes for message to the students, input boxes, multiple-choice inputs, etc). Desmos Activitiesĭesmos Activities build on graphs to allow the instructor complete control over how the students interact with the graphs, and allow student submission of responses either for discussion or for feedback/grading.
