I worked as a substitute science teacher several days this month experiencing the full spectrum from hospitable to hostile environments. I went to two public middle schools, let’s call them schools C and F with ratings in GreatSchools.org for school C scoring 7/10 and school F scoring 3/10. These summary ratings are based on “four ratings, each of which is designed to show different facets of school success: the Student Progress Rating or Academic Progress Rating, College Readiness Rating, Equity Rating, and Test Score Rating.”
For background, I've taught as a substitute teacher at several schools including in New Mexico, Colorado and beginning in March 2022 in North Carolina for WCPSS. I've taught approximately 35 school days in the Apex and Cary areas consisting of 27 assignments in middle schools and 8 assignments in high schools with my focus on math and science although I've also worked in other classes including special education.
Substitute teaching at school C, ten days so far, is consistently awesome. The administrators, teachers, and staff are friendly, helpful, supportive, and great educators. Four science classes per day with 25 to 30 students per class; some classes are quiet and some are very noisy. The students are mostly cheerful, making an effort to learn, and respectful. However, the resources are very scarce and are mostly provided by the teachers for their classroom.
When an eighth grade student asked me “How do fossils form?" I described the process but needed props. I didn’t see any rocks or fossils to show; so improvising, I found an old CD-ROM that could represent a fossil (see photo). Imagine the thick, red science textbook as a slab of billion year old granite basement rock. Over time, rocks erode, rivers and lakes form. A green paper plate represents a lake with mud on the bottom. The animal, disguised as a CD-ROM, is roaming around the area and falls into the lake eventually getting buried in mud. Only the hard bony parts survive and calcium gets replaced by silica contained in the groundwater turning the bone into a fossil. Then the lake gets buried in sand, dries up and sedimentary rocks form on top, each page of the book representing a rock layer. Maybe the buried fossil parts are found later in an outcrop, road cut, or in drill rig cuttings. We discussed other ways fossils form and it would be great to show real samples of a preserved insect in amber or a piece of an intact wooly mammoth that fell into an icy lake.
This is one example of creative, spontaneous lessons that keeps substitute teaching fun. We did a class review of landforms and geology before they took a test which the teacher assigned and I later found out the classes did very well; I also learned that I should be very selective as to where I go to substitute teach.
