Dr. Gail Rosen and Dr. Youngmoo Kim are members of the D K-12 Program. This program has a duel purpose, one is to introduce and integrate engineering concepts into a high school curriculum. The other purpose is to get students excited about persuing careers in the STEM areas.
Last year I helped develop several lessons with them, and in return they came into my classroom and did a series of labs with my students. Along with the collaboration of Dr. Jerry Silverman from the Ed Department at Drexel, as well as the graduate students, we went on to the National Council of Teachers of Mathematics conference in Washington DC to present the labs developed last year
This year I'm refining the old labs and created a new labs. This includes an image processing lab as well as a sound wave lab.
Image Processing Lab:
This lab has the students become familiar with the mathematics behind modifying digital images. Students will use the concepts of mean and median to detect the edges of an image, as well as to 'denoise' an image and a video.
The students will take their picture using Photo Booth on the Macbooks and perform two modification.
The first modification is to outline only the edges of the image, which is separated into two parts. In the first part of the lab, the students will go through a sample pixel map of an image, and they will learn two methods the computer uses to detect where an edge of an image is. In the second part, they will use a computer program to detect the edges of their actual picture.
The second modification is to 'denoise' an image. Their image will be modified to show two different types of noise - Salt and Pepper and Gaussian noise. The students will then clean the image, first going through a method by hand, then using the Matlab program.
Sound Wave Lab:
This lab the students will be exploring the properties of waves (amplitude, period, and frequency).
