Abstract
This qualitative study explored undergraduate biochemistry students' perceptions of visualization, their mindset beliefs, and challenges in engaging with visual representations. Ten student interviews and two instructor interviews were analyzed using thematic analysis. Students focused on external visualizations, while instructors emphasized internal mental imagery. Some students expressed growth mindset beliefs. However, fixed mindset beliefs about visualization were common among students with self‐perceived aphantasia. Findings suggest the need for targeted instructional strategies to foster visual literacy, support diverse visualization abilities, and align student–instructor expectations.

What This Study Is About
Researchers wanted to know how biochemistry students and teachers understand "visualization"—the ability to see and move complex molecules in your mind. They also explored how students with aphantasia (the inability to create mental images, or a "blind mind's eye") navigate these image-heavy science courses.
How They Studied It
The researchers conducted in-depth interviews with 10 undergraduate students and 2 instructors at a large university. They asked participants what "visualization" meant to them and used a special survey to see if they had a growth mindset (the belief that you can improve your skills with effort) or a fixed mindset (the belief that you are born with a set amount of talent that can't change).
What They Found
The study revealed a major "mismatch" in how people think:
- The Teachers: Thought visualization was an internal skill, like playing a 3D movie of a molecule inside your head.
- The Students: Mostly thought of it as external, like looking at a drawing in a textbook or a graph on a screen.
Interestingly, 2 out of the 10 students (20%) self-identified as having aphantasia. These students didn't "see" molecules at all. Instead, they used "verbal reasoning"—using words and logic to describe how parts connect—to keep up with the class. However, these students were more likely to have a "fixed mindset" about their own abilities, feeling that because they couldn't "see" the images, they could never truly master that specific skill.
What This Might Mean
This research suggests that when a teacher says, "Just imagine this molecule spinning," they might be accidentally leaving some students behind. It suggests that science classes should focus more on physical models and clear drawings rather than just mental "picturing."
Because this was a very small "exploratory" study with only 12 people, we can't say these results apply to every classroom. However, it opens the door for more inclusive teaching that helps everyone learn, whether they have a "movie screen" in their head or not!
One Interesting Detail
One student with aphantasia described a clever "info dump" strategy: because she couldn't "see" the chemical structures in her mind during a test, she would memorize them as facts and draw them all out on her scratch paper the very second the exam started so she wouldn't forget them!
