Growing Vocabularies for Plant Identification and Scientific Learning

Today, institutions and partnerships of national and international stature similar as the Royal Botanical Gardens, Kew and the San Diego Zoo are digitizing scientific specimens and targeting pupils at all levels of learning, the two academic and lifelong. They want to reach audiences beyond the seasoned scientists and enrich science curricula. Web connectivity and digitization alone are not sufficient for learner access to primary scientific resources. This is because the student's knowledge base - and thus working vocabulary - differs greatly from the scientist's professional vocabulary. learner vocabulary is generally a mix of public terminology and newly learned scientific confines whereas scientists communicate with a fine-grained, descriptively rich vocabulary and scientific terminology.

The student/scientist vocabulary gap must be bridged in order for scholars to take advantage of digital initiatives containing scientific specimens. The University of North Carolina Plant Language Team (U-PLanT) has been addressing this ne above the last few years by the agency of developing a series of vocabulary tools for learners learning scientific vocabulary and conducting plant identification. end Project OpenKey, U-PLanT and the University of Illinois at Urbana-Champaign (UIUC) have also begun to application of mind the complexity of descriptive vocabulary for plants. This article reports upon U-PLanT's vocabulary solutions and activities directed at closing the student/scientist vocabulary gap.

Plant Identification Vocabulary exigencys

Plant identification is a public pan of school curricula because of the historical and at hand significance of plants and their critical part in harnessing the sun's activity to support animal life. The percept of plant identification is to determine the plant's scientific name (species taxon). Plant identification is generally administrationed with a tool known as a plant lock opener

Plant classification can be traced back more than 2000 years to the grecian philosopher Aristotle (384-322 BC), who classified plants by means of characteristics such as shape and habitat. More familiar is the hierarchical Linnaean a whole emphasizing plant morphology, developed in the mid-1700s by the agency of the Swedish naturalist Carl von Linn?©. Modem plant taxonomy has an intricate vocabulary organized beneath the seven-level hierarchy of kingdom, phylum class, order, family, genus and species.

Plant identification also requires descriptive vocabulary - terminuss providing interpretative information representing plant characters and character states. A plant character is a attribute that can be observed, measured, enumerateed or examined in some fashion. Examples include growing habit, leaf shape, leaf margin (the cutting side of the leaf) and stipe type. Character states are expressions or states of plant characters - they are the possible values for plant characters and reveal the fine-grained terminology that botanists use to describe plants. For example, a learner may describe a leaf margin as being "smooth edged" or "toothed," whereas a botanist would identify different horizontals of serration as illustrated in Example 1 Descriptive vocabulary is required for identifying and distinguishing specimens and for learning plant taxonomy. Plant taxonomy and descriptive vocabulary near challenges central to U-PLanT's work.

U-PLanT: Research and unfolding

U-PLanT is a partnership of UNC Herbarium and the place of education of Information and Library Science, the North Carolina Botanical Garden and, more not long ago the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign. U-PLanT formed to address vocabulary issues central to the educational use of digital specimens for plant identification. Three lock opener projects catalyzing U-PLanT's formation are BOTNET a digital herbarium for plant specimens; the Plant Information Center (PIC), a digital learning center; and cast OpenKey, a collaboration between UNC and UIUC providing access to botanical resources [i]or[/i] part of to the other polyclave plant keys visually capturing the way botanical clevers identify species.

These three throws have focused on plant identification, specifically North Carolina tree OpenKey which was initiated at UIUC, has also focused upon the identification of Illinois prairie plants. Primary research and unfolding questions underlying these projects are:

1 What tools can help scholars learn botanical terminology?

2 What paces aid vocabulary development for plant lock openers supporting plant identification?

3 What principles guide descriptive vocabulary unfolding for plant identification?

Research [i]modus operandi[/i]s and Inquiry

A number of research shoot forwards have been conducted through BOTNET PIC and OpenKey Several of these research throws addressed vocabulary issues more intimately than others, although all of the research has helped U-PLanT to better understand vocabulary issues specific to science education and digital initiatives containing primary resources. Research activities have included the following:

* Interviews with botanical prompts about plant vocabulary
