Physics 2A Proves That Learning Can Be Fun
By Cassie Myers
It sounds like a 鈥淩eading Rainbow鈥� platitude: Learning can be fun! But what鈥檚 hidden inside the clich茅 may be the key to the future of education. Active learning, a type of education that involves students working directly in interactive labs to address concepts, discuss problems and understand subjects on a deeper level, has been proven effective in . But it鈥檚 also effective on the ground. In the reformed physics course Physics 2A at San Jos茅 State, the students are the proving ground.
鈥淏efore taking the class, I expected another boring class full of lectures and labs in which no one had any interest in what was going on,鈥� says Dominic Carillo, 鈥�27 Aviation. 鈥淚 could not have been more wrong. On a surface level, Physics 2A gave me a decent understanding of the fundamentals of physics. However, if we dive deeper, it allowed me to see just how fun learning could be. The lack of heavy lecturing and emphasis on learning through experimentation made for a very effective learning experience that is sure to stick with me.鈥�
Physics 2A is a physics course for non-majors, a prerequisite for degree tracks including aviation, kinesiology and biology. As Cassandra Paul, professor of physics and astronomy, explains, in the past it was a more standard course: three hours of lecture and three hours of lab a week. But Paul, who learned about active learning in graduate school at UC Davis, brought its concepts to 91传媒厂 when she was hired in 2012. With time and the help of many contributors, she integrated active learning into a newly redesigned Physics 2A, now called reformed physics. Since 2015, every Physics 2A section at 91传媒厂 has been taught in this style.
鈥淭he focus is really on student collaboration and student sense-making,鈥� Paul explains. 鈥淚f you walk into the classroom you immediately know it's different because students are up at the boards talking about physics concepts. When I brought the course with me [from Davis], I had to make a lot of changes to the classrooms [to set them up for active learning]. We had to get whiteboards on the wall, we had to get movable desks and mobile chairs so the students could talk to each other.鈥�

The LAs
Physics 2A still has a lecture component, which is held online, but its main focus is the discussion labs, which involve active experimentation and collaboration. Each discussion lab is a section of roughly 20 students and includes an instructor and a learning assistant (LA), an undergraduate who successfully completed the course and is on hand to help guide current students. The active learning model turns students into teachers, teachers into students and everyone into curious physics disciples.
The LA component of the class is especially noteworthy, because the students who loved Physics 2A are eager to return and share their enthusiasm. LAs are hired by the Peer Connections program and are often placed in Physics 2A sections soon after, where they begin 鈥淟A-ing鈥� while simultaneously taking a 3-unit LA training course through the Science Education Program that teaches them the basics of pedagogy, the science of education and how to implement active learning.
鈥淎ll ideas are welcome and we respect all opinions. We never directly say, 鈥榊ou're wrong.鈥� That's very important for students, especially when it鈥檚 their first time taking physics. We don't want them to feel under-confident.鈥�

An interactive class
The LAs are true believers. Even though they emphasize the fun of the course, they also take their jobs very seriously. Anushree Bhattacharya, 鈥�26 Molecular Biology, speaks like an education professor even as she bubbles over with enthusiasm, citing Bloom鈥檚 taxonomy and metacognition offhandedly in a 30-minute conversation.
鈥淲hen I [first] came to this class, I thought physics was such a difficult topic,鈥� she remembers. 鈥淏ut the class structure made me feel like I can learn anything if I know how to organize things. It鈥檚 a very forgiving class. I enjoyed physics 2A very much, [especially compared to] my other stressful classes.鈥�
As an international student from India, she remembered high school physics as what Paul describes as 鈥減lug-and-chug:鈥� you work with an equation, you plug in the numbers and you find out the answer. So she was amazed to find that Physics 2A was so much more interactive.
鈥淲e always write our answers on whiteboards 鈥� the instructor tells us that everyone should take one colorful pen and write on the board,鈥� she says. 鈥淎ll ideas are welcome and we respect all opinions. We never directly say 鈥榶ou're wrong.鈥� That's very important for students, especially when it鈥檚 their first time taking physics. We don't want them to feel under-confident.鈥�
She also loves the exercises that demonstrate various concepts in physics. Like Paul, she mentioned a particular favorite that appears early in the course: heat packs. According to the three-phase model of matter, something that turns from liquid at room temperature to solid should freeze (like water turning into ice). But as Physics 2A instructors demonstrate, a heat pack can turn solid and heat up at the same time. How does that work?
Paul mentioned another favorite exercise: two pool balls running down two tracks at the same time, one wide and one narrow. Students would expect the balls to reach the end at the same time 鈥� but they don鈥檛. Why not? Rotational kinetic energy.
Paul even remembers a kinesiology student marveling at an illustration of torque that showed a human arm pulling on a string: 鈥淚 fundamentally don鈥檛 understand arms,鈥� the student breathed, and yet another physics fascination was born. The exercises are designed to make students curious, and the experience clearly sticks with them much longer than a scribbled-down equation or memorized fact.
Physics 2A In Action
Fewer students dropped the reformed Physics 2A when compared with traditional course it replaced.
Historically marginalized students are
more likely to pass Physics 2A than the traditional course聽it replaced.
The CLASP Physics 2A course聽is correlated with at least
more students passing Physics 2A, and
extra students graduating from 91传媒厂 per year.

News you can use
The LAs are also perfect examples of how the class can be, as Paul describes, 鈥渢ransformative.鈥�
As a molecular biology major, Bhattacharya initially questioned the relevancy of physics for her degree. But once she realized how much the class was digging into conceptual understanding, she realized the skills she was learning could be applied more broadly. She liked how the course provided 鈥渕ultiple perspectives鈥� 鈥� the students learned there was more than one way to approach or solve a problem, and that flexibility was far more valuable than the right answer to a math problem (although naturally they got there, too).
Josh Milstead, 鈥�26 Management Information Systems, has LA鈥檇 for the class for three semesters and agrees with its philosophies. 鈥淭hrough trial and error, we adapt to the unpredictability of science and complex models of thinking throughout college and beyond,鈥� he says.
The course actually changed his career trajectory 鈥� originally an engineering major, he transferred to business because of his experiences as an LA. 鈥淚 found that I enjoy interacting with my co-workers and peers, and I wanted to find a job that combined networking, technology and business, which is MIS,鈥� he explains. He plans to work in the 鈥渢ech business field鈥� and even mentions becoming a professor 鈥渟ometime down the line.鈥�
Dominic Carillo, a fellow LA who took the course during his freshman year, didn鈥檛 change his career trajectory, but the course helped him reset his approach to his own goals.
鈥淢y goal is to one day be a pilot for any of the major airlines,鈥� he explains. 鈥淧hysics 2A made me look at that goal from a different perspective. Before I can fly for the airlines, I will most likely have to be a flight instructor. In the past, I always hated the idea of this and saw it as merely a means to an end. Now, after taking Physics 2A and being a learning assistant, I鈥檝e seen that learning and teaching can be fun and engaging. My new plan is to still fly for an airline, but to take my time and enjoy the journey to get there.鈥�

Stop LA-ing us
Carillo, Milstead and Bhattacharya remember their own LAs fondly, and seek to be another link in the long Physics 2A LA chain.
Carillo calls his LA 鈥渁 really friendly guy who made learning physics far easier than a traditional lab could have. He made the experience a fun one, and I hope to give my students the same experience.鈥� He adds, 鈥淚 see myself as a hands-on learner, so being able to do experiments was always fun for me. Now that I鈥檓 on the other side of the experiments, I鈥檓 excited to help guide my students through them and drive them to deeper thinking.鈥�
Milstead encourages his students to be curious and open-minded. 鈥淚nteracting with my students in a role where I鈥檓 both an 91传媒厂 employee and an undergraduate student like them helps us relate to each other,鈥� he explains. 鈥淎nd I try to lighten the mood with my jokes. Sometimes they think I鈥檓 funny.鈥�
Bhattacharya has a natural gift for teaching, brought on by a childhood spent surrounded by teachers and helping younger cousins, but she also has gained a great deal from the LA experience.
Before her time as an LA, she describes herself as 鈥渁 very shy and introverted person. Just starting a conversation was so difficult for me, but after joining this learning assistant program, I鈥檝e been able to communicate and socialize with so many people,鈥� she says. 鈥淚 know so many faces on campus that when I'm walking from one class to another, I hear 鈥楬i, Anushree, how鈥檚 your day going?鈥� and I feel really good.鈥� She credits this and 鈥渙ther wholesome experiences鈥� with 鈥渁dding to my college campus experience and also giving me a lot of professional development.鈥�
She鈥檚 currently an LA for a different course, Biology 30, where she鈥檚 incorporating her active learning training into a larger, more lecture-based course by sharing community building exercises with her students. (Her current plan is an icebreaker: 鈥淎re you more flora or fauna?鈥�)
And it doesn鈥檛 even stop in the classroom; it鈥檚 bled into every part of her life. When her friends ask her for help with schoolwork, she draws on her training. They want the easy way out, begging her, 鈥淒on鈥檛 LA us 鈥� give us the answers.鈥�
But of course like any good LA, she refuses. 鈥淚 tell them, 鈥業 can't do that. I'm too into this role. I'll help you get the answers, but I won't tell you the answers,鈥欌�� she remembers. 鈥淎nd they say, 鈥極h my God, it can never come out of you.鈥欌��
