Grading science labs in high school often focuses on completion rather than critical thinking. Teachers face challenges when student work starts to blur—identical graphs, similar conclusions, and answers that feel generic. The goal shifts from assessing whether students followed instructions to understanding if they grasped the science behind the experiments. One teacher, Jodie Deinhammer, reworked her approach to prioritize student thinking over compliance.
Encouraging Student-Generated Data
In a medical microbiology class, students tested how different sugars affected bacterial fermentation. Each group ran the same experiment with a unique sugar and submitted results via a Google form. The teacher then displayed combined class data, prompting students to annotate the table with questions, assumptions, and observations. This method revealed deeper scientific reasoning than traditional conclusion paragraphs.
Students quickly noticed flaws in their experimental designs. Discussions shifted from blaming mistakes to analyzing data and evidence. This mirrors authentic scientific inquiry, where questioning results is central. She noted that students became more engaged with the material, focusing on understanding rather than just finishing tasks.
Visualizing Concepts Through Annotations
In anatomy and physiology, students dissected specimens and annotated images instead of taking vocabulary quizzes. They labeled structures with directional terms and medical terminology, demonstrating understanding in a more hands-on way. For example, annotated images from a kidney dissection showed them applying terminology directly to their observations.
A Valentine’s Day lab on heart rate involved creating infographics to summarize data. Students designed visual snapshots with fewer than 10 words, then defended their findings in group discussions. This approach required them to think critically about data collection and communication, moving beyond rote memorization.

Presenting data analysis as an infographic is a favored method. Students are prompted to create a snapshot or infographic of data, such as “If you could share your data with one visual and fewer than 10 words, what would it look like?”
Grading Through Rubrics, Not Just Compliance
Despite the shift, grading remains structured. Rubrics assess multiple categories, including pre-lab preparation, experimental design, data analysis, and reflections.
The teacher emphasized that labs are opportunities to uncover student thinking. She highlighted how rubrics provide clear criteria for evaluation, allowing for more consistent feedback across different instructors. This system also encourages students to take ownership of their learning process.
This shift allows teachers to see what students truly understand, encouraging ownership of learning and deeper engagement with scientific concepts.
