Histology education for first-year undergraduates is often limited to the passive observation of premade slides due to the multi-day timeline of conventional paraffin processing. This disconnect between conceptual learning and practical skill development represents a significant pedagogical gap. We present an innovative, engaging, and highly practical laboratory module that employs microwave-assisted tissue processing to reduce protocol duration from more than 72 hours to less than 3 hours, enabling a complete hands-on histology experience within a single laboratory session. Designed explicitly for the freshman biology curriculum, this module directly addresses the logistical barrier that has long precluded authentic histological practice at the introductory level. Its originality lies in the strategic adaptation of a clinical pathology technique into a safe, reproducible, and inquiry-based undergraduate activity, transforming a traditionally observational topic into an active learning experience in method optimization. The module's attraction is rooted in its immediacy and active learning design-students witness the cause-and-effect relationship of each processing step in real-time and produce their own diagnostic-quality slides. Its practical utility is demonstrated by its use of common laboratory reagents, adaptable equipment, and seamless integration into existing course schedules. We explicitly align the module with Next Generation Science Standards (NGSS) Science and Engineering Practices, particularly "Planning and Carrying Out Investigations" and "Constructing Explanations and Designing Solutions," thereby bridging a core laboratory technique with national science education frameworks. Student learning was evaluated through a pre-/post-concept assessment and a skills-based rubric. Results from a pilot implementation (n = 52) showed statistically significant gains in conceptual understanding and high competency in technical execution. This protocol offers a transformative approach to teaching core histological concepts, fostering early technical literacy, scientific curiosity, and design-thinking skills in first-year students.
Is food a unifying concept in biology? With the new subdiscipline of nutrigenomics, it might be. Food is arguably the most focused on aspect of everyday life besides sleep. In fact, even in sleep, humans often dream about food. In prehistoric times and even today for many people, the procurement of food requires skillful efforts, cooperation, and energy. Today, in the modern, industrial world, food is no longer appreciated from this perspective. Biology students, like most people in the modern, industrial world, often experience a disconnect between food, nutrition, and the planet. For biology students that disconnect is exacerbated and further extended to concepts of nutrient procurement, cellular respiration, ecology, evolution, and genomics. Such concepts as nutrient scarcity or abundance and how food shaped human cultural practices and contributed to genetic and phenotypic divergence are part of the evolutionary framework of nutrigenomics. Our current genome and food-related practices have diverged from our primate relatives and continue to impact our genome in the present. From tooth shape to digestive enzymes, human digestive physiologies vary greatly due to geography, cultural practices, genetic variation (SNPs), and epigenetics. There is now, however, a connecting concept, which is a branch of genomics known as nutrigenomics, that has the potential to draw in and refocus student attention on many of the basic biological ideas students struggle with.
Biology has the potential to enrich and expand students’ everyday experience. Unfortunately, most students do not connect school learning to their out-of-school experience. Drawing on transformative experience theory, we developed the Seeing Science project as a way of bridging in-school and out-of-school experience. The Seeing Science project involves four steps: (1) identify re-seeing opportunities, (2) encourage re-seeing in everyday life, (3) share re-seeing experiences via technology, and (4) discuss re-seeing experiences in class. The Seeing Science project is associated with undergoing transformative experiences (i.e., experiences of seeing the world through the lens of school content in meaningful new ways) and can be implemented with readily available technology.
