A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

Tree thinking, the understanding of the evolutionary relationships between organisms depicted in different types of tree diagrams, is an integral part of understanding evolution. Novice learners often read tree diagrams differently from specialists, resulting in diverse interpretations of the relationships depicted. The aim of this study is to…

This qualitative study analyzed grade 12 biology students' answers to written extended-response questions that describe hypothetical scenarios of animals' evolution. We investigated whether these type of questions are suitable for students (n = 24) to express a meaningful understanding of evolutionary theory. Meaningful understanding is comprised…
