Plant blindness refers to the tendency of people to overlook and undervalue plants in their environment, which can have negative consequences for both the environment and human well-being. As pre-service teachers play a key role in shaping the environmental attitudes and knowledge of future generations, it is important to assess their level of…

Requiring students to create weed collections is a common technique for teaching weed identification. Data compiled over 18 years from students' weed collections in a college-level course included over 350 species of plants. Almost half of the specimens belonged to the Asteraceae or Poaceae. The 30 most frequently collected species accounted for…

We used a novel approach that combined direct PCR of plant tissue and SRAP DNA fingerprinting to seek to identify the crosses made in "Brassica rapa" used in the Wisconsin Fast Plants. Our goal was to develop a rapid method for students to use in a biology, botany, or genetics class to identify the parental types (purple stem, non-purple…

Biodiversity is a multidimensional concept, and its integration into school curricula is essential for promoting sustainable development. Plants are central to the biodiversity of ecosystems; however, student teachers often fail to recognize them and understand their importance. This phenomenon, known as "plant blindness," was first…

Scientific drawing and writing are critical to the development of observational and recording skills in biology. However, it is unclear how the process of drawing and writing contribute to the learning of plant taxonomy. In the present study, 41 adult botanical novices studied a suite of UK native plant species using two methods: labelled drawing…

Limited awareness about nature and its species can have a negative influence on children's relationship to nature. Plant species recognition and outdoor education are perhaps the easiest way to approach nature relationships and increase knowledge. Unfortunately, it has been shown that people do not recognize plant species very well. This…

A weed garden was constructed to quantify and improve identification skills among clientele. The garden was planted with over 100 weed species based on surveys on problematic weeds. The weed garden proved useful for introducing additional hands-on learning activities into traditional lecture-based seminars. Through seminar and field day attendee…

Taxonomic education and botany are increasingly neglected in schools and universities, leading to a "missed generation" of adults that cannot identify organisms, especially plants. This study pilots three methods for teaching identification of native plant species to forty-three adults engaged in the participatory science project…

The "Needs of Seeds" formative assessment probe can be used to find out whether students recognize that seeds have needs both similar to and different from plants and other living organisms (Keeley, Eberle, and Tugel 2007). The probe reveals whether students overgeneralize the needs of seeds by assuming they have the same needs as the adult plants…

The National Science Education Standards prescribe that an understanding of the importance of classifying organisms be one component of a student's educational experience in the life sciences. The use of a classification scheme to identify organisms is one way of addressing this goal. We describe Conifer ID, a computer application that assists…

The World Wide Web and other computer-based media are new teaching resources for plant identification. The purpose of the experiments reported here was to test whether learning plant identification for woody and herbaceous plant material over the web was as effective, more effective, or preferred by undergraduate students when compared with…
