【Introduction】

The video is divided into these parts:

Title– The relationship between acute triangle ratios
What are the acute triangle scores? 【 Knowledge points 】
Text definition of a tangent, a sine etc.【 Concept of knowledge points 】
Corresponding mathematical formula【 Concept of knowledge points 】
The application of knowledge points in life 【 Application of knowledge Points 】

【explain why you decided to do this assignment/project】

This video assignment was assigned by Math 1 during the May Day holiday. I have never tried to learn a knowledge point better by making explanation videos before, which is a new attempt.

【how you were doing it】

First, I collected the lecture notes of this knowledge point in the past. Then, I went online to see how others taught this knowledge point and collected relevant materials. Then I write the content that will appear in the video, and finally, I record the sound of the lecture and editing it.

【which knowledge you applied】

Language Use and Use of Digital Media / Visual Displays

【Self-reflection】

【explain what you have learned while making this assignment/project】

I have a deeper understanding of the relationship between the acute Angle triangle ratio, the math knowledge point I mainly study in this video. Secondly, how to prepare an instructional video and how to learn a knowledge point in this way. Formulas, examples, concepts, etc

【Competencies and Skills】

Oral Presentation

Skill C — Language Use

Follow the text shown in the video. I will refine my language in addition to repeating the existing concepts on the blackboard, and explain the reasoning process of the topic and the links between the knowledge points so that the audience can understand the video more easily

Adjust between the sound of the BGM and the sound of the explanation so that the BGM does not drown out the sound of the explanation

Skill E — Use of Digital Media / Visual Displays

When I was designing the content of the video, the speech part was accompanied by the text part of the video. Because according to my experience, when watching a teaching video/listening to a lecture, the information on the blackboard seen by naked eyes is always clearer and more impressive than what is said orally.
So all the basic and most important content is recorded in the handwritten text on the video board.

Leaning How To Lean

Skill E — Extending ideas – practical usage, model debugging

At the end of the video, I mentioned how to use the knowledge point in real life. Use the relationship between acute triangle ratios in this video to measure the speed of the car. Use a question that relates to information in real life to explain the application of this knowledge point in life

A real example can better explain a text content, which is also the application of mathematics in life

【improve】

I think I could add more information. Not only is the basic expansion and understanding of the knowledge points, in the explanation part can add more of my own understanding, in the part of the example in addition to the use of life can also have other examples for reference. It will make the people who are watching my video to understand better. So the understanding of the knowledge points can be deeper.
