Author Profile

This activity has gone through a workshop review process.

This resource was reviewed as part of the May 2009 MARGINS Mini-Lesson Workshop. Each activity received verbal feedback from two participants who had reviewed the activity and activity sheet using these guidelines. Authors revised the activities and activity sheets in response to these comments during the workshop.

Summary

Each student interprets one MARGINS study that he/she finds particularly interesting, describing the study in a two to four minute oral presentation in class. Students may present one, and only one, visual aid as an overhead or PowerPoint figure. Students are directed to approach this presentation as a "news flash," a feature presentation made on an evening news program.

Learning Goals

  1. To explore cutting-edge research facilitated by the MARGINS program.
  2. To present scientific information in a clear and concise oral presentation.
  3. To develop reading skills, including interpreting and synthesizing scientific information.
  4. To illustrate that geoscientists are constantly making new discoveries in a dynamic, modern, ever-changing field.

Context for Use

Short "news flash" oral presentations may be assigned to students at any level, however, material in the MARGINS "nuggets" are most appropriate for mid- to upper-level students. The activity is general enough that an instructor can narrow topics to a particular area (e.g., geophysics, tectonics, or structural geology) or leave the possibilities broad (e.g., any topic addressed in the MARGINS website). For a small class, assigning multiple short presentations on different topics throughout the semester would be particularly effective in improving student skills.
Instructors are encouraged to discuss how to give effective oral presentations and how to distill a lot of technical information into a concise and clear summary for an audience of their peers.

Description and Teaching Materials

The MARGINS website contains a wealth of information. I highly recommend that students start with the one-page descriptions that the MARGINS program refers to as "nuggets". Each "nugget" is focused on one research project and typically contains one high-quality figure.
Continental margins are the transition zone from continents to the deep sea. Active margins coincide with plate boundaries, marking an abrupt change in oceanic bathymetry. At passive margins, the sea floor gradually deepens across the continental shelf, slope, and rise. The MARGINS program promotes continental margin research through funding by the National Science Foundation.
To prepare for the oral presentation, students must have access to a computer with an internet connection to access the MARGINS website. Each student gives a two- to four-minute talk in class. Ideally, students would have access to PowerPoint or an overhead projector during their presentations. The assignment handout includes a one-page description of the activity and a series of instructor/peer evaluation criteria.

Teaching Notes and Tips

Synthesizing and summarizing scientific information in a short oral presentation will be particularly challenging for most students. Despite pleas from students, stick to requiring one figure and one figure only for the presentations. This allows students to concentrate on the substance of their talks instead of flashy PowerPoint figures. To this end, direct students to follow these guidelines. Like a news program feature, your presentation should have the following characteristics: Target Audience:
