Food Insecurity: Rudimentary Education For Local Youth (Firefly), Nam-Anh Nguyen, Quynh P. Nguyen, Jane E. Krause

Purdue Journal of Service-Learning and International Engagement

As service-learning becomes recognized as a significant teaching-learning tool for college students, the authors of this article came together to apply for the Purdue University Service-Learning Sustainability Projects Grant. Upon receiving the grant, with the encouragement of Professor Jane Krause and Food Finders Food Bank, the student authors created a project focused on food insecurity education in West Lafayette, Indiana. The main objective was to develop and teach a series of lessons on food insecurity and sustainability to middle school students using interactive activities. A team of Purdue students from various backgrounds was recruited to assist in planning and to …

Exposing Problems Teaching Students Morphological Species Identification, Trevor Stamper, Lauren Weidner, Gregory Nigoghosian, Ludmila D. Nunes

IMPACT Presentations

When dealing with physical remains, morphological assessment for species is a traditional approach to entomological specimen identification. A dichotomous key guides the user through taxa determination for a specimen by providing a series of dual-choice nodes that center around morphological differences. Each nodal choice leads to either a new set of dichotomous choices or a taxa decision. We evaluated student’s ability to utilize a dichotomous key down to species for a limited set of taxa, by reviewing their nodal decisions along with their confidence level using a Likert scale (1-5).

Along with individual decision recording, students conducted a post-decision group …

A Model Of The Use Of Evolutionary Trees (Muet) To Inform K-14 Biology Education, Yi Kong, Ankita Thawani, Trevor R. Anderson, Nancy Pelaez

PIBERG Publications

Evolutionary trees are powerful tools used in modern biological research, and also commonly used in textbooks and classroom instruction. Studies have shown that K-14 students have difficulties interpreting evolutionary trees. To improve student learning about this topic, it is essential to teach them how to understand and use trees like professional biologists. Unfortunately, few currently used teaching frameworks for evolution instruction are designed for this purpose. In this study we developed the Model of the Use of Evolutionary Trees (MUET), a conceptual model that characterizes how evolutionary trees were used by professional biologists as represented in their research publications. The …
