Guide to Metabolic Biochemistry

Learning metabolism in higher education represents a long-standing challenge due to the abstraction of its concepts and the complexity of its interconnected networks. The students' tendency toward rote memorization, combined with the proliferation of unverified digital resources, demands teaching materials that combine scientific rigor with a pedagogically sound structure. In this context, this Guide to Metabolic Biochemistry emerges as a comprehensive resource for active learning and formative assessment in experimental and health sciences degrees.

The work is grounded in evidence from cognitive psychology, addressing cognitive load reduction through hierarchical summaries and visual diagrams that facilitate a mechanistic understanding. Its core consists of a battery of 715 multiple-choice questions (with five options and up to three correct answers) and short-answer questions, all rigorously classified according to the revised Bloom's taxonomy. This categorization allows for a progression from factual recall to analysis and evaluation, promoting metacognition and the testing effect (retrieval practice).

The data from the guide reflect a balanced design: 49.5% of the items focus on foundational cognitive levels (B1-B2), while the remaining 50.5% are distributed across middle and higher levels (B3-B6). Furthermore, the structural complexity of the tests—where 61.3% of the items feature multiple correct answers—minimizes guessing and encourages deep information processing.

Finally, the project is defined by its commitment to educational equity, being distributed as an Open Educational Resource (OER) under a Creative Commons license on GitHub and Zenodo. This digital and open nature not only facilitates accessibility and inclusion but also invites the teaching community to engage in continuous updates, consolidating a living platform for collaboration and innovation in biochemistry education.
