Since our topic is solving functions, my search topic is graph quadratic functions, which is part of the big topic. After I searched on different video websites, I did not find any videos of forced interaction. Most of them explain that knowledge directly, and in the video I chose, it also gives examples of each type of equation. Learners need to follow the video and take notes by themselves. When they study through videos, they can easily stop the video and take notes. It can avoid missing points. Thus, learners are able to have the full notes and watch the video again if they don’t understand the point. The recommendation I want to give is practise. Practise makes perfect. After absorbing new knowledge, learners have to get some practise to consolidate the knowledge. They should be able to graph quadratic functions with their hands. For online graphing, I strongly recommend Desmos, which is a graphing tool website. This tool allows learners to graph a specific parabola or flexible parabola, which means the shape is not prescribed and changes with the value of the function. Learners can fully understand how the graph changes as the values change. Also, learners can check their own graph in Desmos after learning how to graph the function. We create some functions, and learners will graph them on paper and submit the PDF of their work through email, Discord, or Mattermost. Sometimes learners will have problems figuring out the correct graph. Discord and Mattermost are good ways to ask questions of teachers and other learners. This activity will not cause much work. The work is manageable and worthwhile because the problems provided are the same for every learner. The activity should be scaled for larger numbers of students, like from easy to hard.
