Biology Student Pre-Post Test Scores for Central Dogma Lesson

Alyssa N. Olson published a dataset on figshare in 2026 supporting a study on assessment alignment in biology education. The data likely contains pre- and post-test scores from two groups of introductory biology undergraduates (n=39 and n=57) who took different assessments on the central dogma of molecular biology. The dataset is small, at 694.8 KB, and is provided as a PDF file.

Use Cases

• Comparing learning gain detection between adapted concept inventories and lesson-customized assessments based on the study's findings.
• Analyzing the relationship between student exam performance and pre-post score gains mentioned in the description.
• Investigating how item-level performance on assessments drives overall learning gains, as suggested by the results.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• The study design involved two distinct student groups (n=39 and n=57) for comparison.
• The research context is clearly described, focusing on a specific lesson (central dogma of molecular biology).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data is embedded within a PDF, which may complicate direct analysis.
