This material was originally developed by Spreadsheets Across the Curriculum as part of its collaboration with the SERC Pedagogic Service.


In this Spreadsheet Across the Curriculum module, students work through the coastal vulnerability index and its application to the coastline at Point Reyes National Park as described in an online USGS Open File Report. That study divided the shoreline into ~1.5-km quadrangles and evaluated six coastal vulnerability factors on a scale of 1 to 5 at each quadrangle. The vulnerability factors include three geology factors and three process factors. The former three are: "geomorphology" (relating to resistance to erosion), history of accretion/erosion, and the slope of the coastal profile. The latter three are: rate of sea-level rise, wave exposure, and tidal range. The index is calculated by aggregating the six scores. Students reproduce the calculation by using a color-coded, conditional-formatted spreadsheet laid out on spreadsheet grid to simulate a map of the Point Reyes shoreline. The quantitative literacy point of the module is the use of scores based on ordinal scales.

This material is based upon work supported by the National Science Foundation under Grant Number NSF DUE-0836566.

This module is designed for potential use in the Geology of National Parks service course at USF. The course is offered as an online course every semester. It includes readings from Parks and Plates, weekly quizzes based on that textbook, and weekly student activities designed to align the course with the University's general education requirements. This module is intended to be one of those activities, with the specific goal of meeting the gen-ed quantitative literacy dimension.

The module is a PowerPoint presentation with embedded spreadsheets. Click on the link below to download a copy of the module.

Optimal results are achieved with Microsoft Office 2007 or later; the module will function in earlier versions with slight cosmetic compromises. If the embedded spreadsheets are not visible, save the PowerPoint file to disk and open it from there.

The above PowerPoint presentation file is the student version of the module. It includes a template for students to use to complete the spreadsheet(s) and answer the end-of-module questions, and then turn in for grading.

An instructor version is available by request. The instructor version includes the completed spreadsheet. Send your request to Len Vacher ( by filling out and submitting the Instructor Module Request Form.

Teaching Notes and Tips

The module is constructed to be a stand-alone resource. It can be used as a homework assignment, lab activity, or as the basis of an interactive classroom activity. It was used as an out-of-class activity in a senior-elective course, Environmental Geology of the National Parks (for geology majors and nonmajors), during development of the module in Spring 2010, and as an out-of-class activity in Computational Geology (a QL course for geology majors) in Fall 2010 and Fall 2011. In general, the students considered this module to be one of the more elementary modules in the collection. It is now one of the modules that is rotated into the online introductory-level Geology of National Parks course.


There is a slide at the end of the presentation that contains end-of-module questions. The end-of-module questions can be used to examine student understanding and learning gains from the module. Pre/post test, pre/post test answer key, and answer key for end-of-module questions are at the end of the instructor version of the module.
