I studied computer engineering in college. I went to school on a 4-year scholarship, so I had 8 semesters to get a degree before the money ran out. This is important because I had to pass every class I took. I couldn’t fail a class or I might lose my scholarship, and if I had to repeat a class that was a prerequisite, I might not graduate on time.
Along the way, I took my first class in circuits, and I got a B. Good enough to pass and move onward to the next class. However, I knew at the time that I was struggling to understand circuits. I did reasonably well on the assessments, but I didn’t really get how an RC or LC circuit worked, or the meaning behind Maxwell’s equations or Gauss’ formula. I could use ratios to calculate the output of a transformer, but I didn’t really understand why they worked. I could answer questions about transistors but was helpless when it came to designing something with them.
I remember wishing that I could just retake circuits even though I had passed. I felt at the time that I had to move on to the next class. A lot of electrical engineering went over my head because I was a little lacking on the fundamentals.
I’m reflecting on this now, because at the middle school level I often have students repeat a class. I’ve had students that have signed up for CS or Electronics 2 or 3 times. Does this ever happen in a high school? It can be a great experience for me and the kids. The benefits are different for every student.
Take James, for instance. James took Computer Science Exploration last spring, and signed up for it again this spring. Last year, we made projects in Unity and James made a little forest scene you could walk around. This year, James made an immersive Robot War game, with marching animated robots, a scoreboard, and rocket launchers. In one year the growth was incredible. It was clear James understood what he was doing much better than he had the year before. He enjoyed retaking the class and going farther with the material.
Kamiya took Electronics in 7th grade and then came to my classroom at the beginning of 2nd semester. She asked if she could be a TA during the spring, and I said yes. She continued to be a TA in Electronics for 2 consecutive semesters. She was interviewed about the class partway through her second time as a TA. She said she loved learning about electronics, and it was her passion. She never minded being in the same class over and over, because she learned something new every time. Things were taught in a slightly different way, with different projects. Kamiya came with me to conferences and presentations often. I knew if I asked her to present to our superintendent, or congressional representative, or at the ISTE conference, she would do a good job. Kamiya is a generally shy kid who really seemed to blossom when she was making things with technology. She went on to participate in a nationally-honored FIRST robotics team in high school, and I like hearing about what she’s up to.
Luis took Electronics for the first time and did reasonably well and got a B. I knew he probably didn’t understand the content solidly, but he did a decent job and passed. When he signed up for the class the second time, I offered him a choice and said he could either take the class as a student, to learn the material better, or he could take the class as a TA and help others. He chose to take the class as a TA. Even though he wasn’t a top-tier performer in the class the first time around, this was an option that worked for him. Patrick is shy and needed support when it came to friendships and bullying. Being a TA helped him learn more about electronics but mainly improve his status. He helped other students when he could and alerted me to their needs when he couldn’t. He told me that he felt the class was a safe haven for him, where he didn’t feel any academic or social pressure. I suppose he needed that more than he needed to know about Ohm’s law.
For James, Kamiya, and Luis, re-taking a class helped them to grow in ways they needed. I love that our school gives kids the option to sign up for a class a second time – no penalty, no pressure. If you want to learn a little more and in a slightly different way you can re-take a class and tailor the experience to meet your needs.
I wish I’d had that option in college with circuits class. Or I wish I had known about it and had taken it. I think it would have really helped me grow as an engineer to learn the same material again, with no pressure and no risk, just to make sure I understood it.
