Hello! My name is Marcie Samayoa and I am a tenth year high school chemistry teacher in Los Angeles, CA.
My teaching journey began at UCLA, where I earned my Bachelor of Science degree in Biology with a minor in Science Education. I later earned my teaching credential from CSUN and began teaching high school science in 2016. I became a National Board Certified Teacher (NBCT) in 2025.
Throughout my years in the classroom, I’ve consistently encountered students who feel intimidated by science. Instead of accepting the “science is hard” narrative, I’ve made it my mission to reflect on my teaching practices and make science accessible to everyone. By incorporating cognitive and behavioral science principles, I’ve helped many students overcome the perceived difficulties of science. Over the years, I’ve received many thank you messages from students who have successfully applied these strategies not only in science but in other subjects as well.
The purpose of this blog is to share evidence-informed instructional practices that can help educators enhance their science instruction. Of course, these strategies can be applied across all subjects. All are welcome!
Thank you for visiting and welcome to Scientists in the Making!
