Reflection: Polynomials with Complexes… Complex Zeros that is! - Section 3: Explanation: Complex Zeros


This year my school is focusing on improving students’ ability to retain information. One instructional strategy we have been asked to implement is Cornell note taking. I have never used this strategy as a student or as a teacher. I found this video extremely helpful in understanding Cornell notes and it really made me excited and helped me to understand the benefits of this style of note taking for students. I also used the video from 2:00 to about 4:00 to show my students why Cornell Note taking is so important.


This is my first attempt at teaching my seniors this strategy. I have decided to provide students with some guided notes, Notes Polynomial Theorems and Imaginary Numbers.docx. Time has become an issue as I keep pushing lessons back and adding more time, I wanted to speed note taking up by not having students write so many words. Also, this Cornell note template will help students if they are new to this style of note taking.

Below are some good examples of the notes I collected on test day. I will be using these to demonstrate to students what 'good' notes look like. Many of my students still have a lot of room for improvement on their Cornell Note taking skills.

Unit 2: Polynomial Functions and Equations
Lesson 10 of 15

Objective: SWBAT identify the imaginary zeros of a polynomial function and use imaginary roots to find the standard form of a polynomial function.

Big Idea: Personal response systems keep students engaged and monitor their current progress as they find all zeros of a polynomial function.
