I really liked the online TI-84 calculator! It was a really useful tool for visualization, so that the learners could see what you were doing and follow along easily.
It was also really beneficial how you explained smaller details, such as needing to click the (-) instead of -, or the fact that there isn’t an = sign. Many learners may get confused at those small but crucial details, so it’s helpful that you addressed them early on.
One thing for improvement that I notice is that at some parts, maybe you could’ve explained the purpose of what you were doing more, or like what the action would’ve been useful for. Especially since calculators are for applications, so it’s just as useful to know how to use it as it is to know when to use it. For example, maybe when you were doing the graph for the plotted points, you could’ve explained why somebody might choose to use scatterplot versus line graph, or what the line graph would represent. Also, when you were doing left and right bounds, you didn’t really explain the purpose of the bounds (to find the x-intercept(s) in between the bounds). I think that may have caused some confusion for the learners.
In addition, this is a more minor detail, since you already explain things in-depth enough in general. When you were finding which minimums and maximums worked for the graph, I think if you explained why lowering the range would’ve been more helpful (long range = graph taking up smaller percentage of screen, which makes it hard to see), it would’ve been beneficial in further strengthening the learner’s understanding of how graphing works on a calculator.
However, like I said, that is just a small detail as you already do a good job of explaining why something works, like when you explained why you chose the y range.
In general, you did a great job focusing on details, as well as finding ways for the learners to stay engaged, but maybe just work on explaining the purpose and why factor. :)
