Instroduction - Gestures are an integral part of communication among people of all ages and cultures. People gesture during spontaneous conversations with friends. Teachers gesture when explaining a scientific concept to a class. Students gesture as they work together when learning a new scientific principle. So do scientists during "lab-talk."
Research has shown that gestures are not merely idle arm-waving; they are profoundly connected to cognition and perception, and can convey subtle meanings that would be awkward or impossible to convey in language alone. For an educator or education researcher, gestures can therefore provide a window into students' thought processes, even when the students do not articulate their understandings or misunderstandings in words.
This column reviews seminal research on gestures in the domains of problem solving, science education, field-based education, spatial tasks, and scientists' discourse. We present evidence that gestures are of value for both gesturer and recipient, review hypotheses about why gestures are valuable, analyze examples of gesture as used by both instructors and students while discussing geoscience topics, offer suggestions for geoscience educators, and conclude with directions for future research.

Threshold Concepts (Acrobat (PDF) 426kB Apr21 08)

JGE, v. 55, n. 5, November, 2007, p. 434-438
Abstract - This article introduces the idea of threshold concepts as a means to better understand student learning and, hence, to develop an enhanced curriculum to facilitate that learning. The debate surrounding threshold concepts is relatively recent and has mainly been focused within other disciplines such as economics, maths and history. Following on from their contributions to a conference in the UK on threshold concepts in geography, earth and environmental sciences, the authors are seeking to open the debate more widely to the geoscience community and thereby begin to develop an understanding of what this new approach to learning means for our subject area.

The Expert-Novice Continuum (Acrobat (PDF) PRIVATE FILE 545kB Oct9 07)

JGE, v. 55, n. 4, September, 2007, p. 333-339
Introduction - José teaches a capstone course for geoscience majors, and has recently become head of his department's curriculum committee. As José prepares for the first meeting of the curriculum committee and considers the structure of his capstone course, he is thinking about what his department should expect their undergraduate students to know or be able to do by the time they graduate. Some of his students will go on to geology related jobs, particularly in the environmental industry, and others will be attending graduate school in MS or PhD programs. In addition to acquiring a core of factual knowledge about the geosciences, he would also like his students to gain an accurate understanding of important geologic processes, to be able to think critically about spatial data, and to learn to integrate processes and data into a holistic model of the Earth and Earth processes. In short, his goal is to have students learn to "think like a geoscientist" - to move their thinking and skills along the continuum from geology student (novice) to geoscience professional (expert). What does José mean by this, and how can he achieve this goal?

Josepha P. Kurdziel, Department of Ecology and Evolutionary Biology, University of Michigan
This installment looks at whether gender does have an affect on who becomes tenured faculty at colleges and universities. The authors examine the gender balance of undergraduate and graduate students and then discuss the percieved disparity when these are compared to the number of geoscience faculty who are women.

Josepha P. Kurdziel, Department of Ecology and Evolutionary Biology, University of Michigan
JGE, v. 51, n. 1, January, 2003, p. 121-126
In this column, the authors give an overview of current research on what types of mental models students build to understand the world and distinguishes them from one another. They go on to talk about how the type of model a student has constructed affects how they are able to assimilate new information.
