During the pandemic I was forced to learn how to effectively tutor students online. My favorite website to use is Khan Academy, which gives students video lessons and problems whose answers the websites check and explain. The site is extremely versatile for a math teacher, as it divides topics by grades and focuses on Common Core and Advanced Placement standards. It is also visually pleasing and engaging, the only ways to reel in the attention of students during arduous virtual learning. In this photo essay, I will illustrate how Khan Academy presents a unit on the Pythagorean identity in trigonometry. The unit starts with a video explaining the proof of the identity using the unit circle and the Pythagorean theorem. The video contains illustrations with different colors as well as algebra so various types of learners can be engaged. The next video contains an example of a problem in which one must use the Pythagorean identity to find the cosine of an angle in the second quadrant given the angle’s sine value. This type of problem is common on the Algebra II/Trigonometry regents. The site gives the user practice problems such as the one above, which is similar to the problem in the video. One can ask for hints if stuck. Got the problem wrong? No worries, the site will help point you in the correct direction. The site gives positive affirmation for right answers, usually containing bright images of items such as stars and confetti.
