Introduction to Hazard and Risk: Part 1
Summary
Learning Goals
Students will:
 Examine a geologic map of Benton County and consider how the geology affects the distribution of population and exposure to risk.
 Given a row of numbers representing the different classes of structures in Benton County, compute the total number of structures and the percentage for each class.
 Using a table of hurricanes from the Atlantic and Caribbean from 20052010, compute the number of years, number of hurricanes, maximum number in any year, minimum number in any year, and average number of hurricanes per year.
 Use these same tools to compute some statistics for the list of structure types in Benton County.
 Given a table of structures in Benton County organized by construction, compute the percentage of the total for each.
In the process the students will:
 Lean how to read a geologic map.
 Learn how to enter formulas into a cell on an Excel spreadsheet.
 Discover the difference between relative and absolute cell references.
 Learn how cell formulas can be copied to other cells.
 Learn how to find and use some builtin Excel functions, such as SUM, COUNT, and AVERAGE.
 Practice these new skills through repetition on different subjects.

Description and Teaching Materials

Hazard and Risk 1 (PowerPoint 4.3MB May15 12)
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 is the student version of the module. The embedded spreadsheet consists of a template for students on which students complete their work and answer the endofmodule questions, and then turn in for grading. Since this module is designed as a standalone resource, instructions for extracting and saving the embedded spreadsheet are included in the PowerPoint presentation.
This module is offered in two versions: a traditional SSAC version and a new autofeedback/graded (AFG) version. The AFG version: (a) provides automatic and immediate feedback to incorrect answers, including formulas; (b) requires students to complete tasks sequentially by not allowing them to advance until they've completed a task perfectly; and (c) automatically computes a grade and encrypts it into a code the students submit to verify successful completion. The files needed for this version can be accessed from Juster's AFG website.Teaching Notes and Tips
This module is constructed to be a standalone resource. It can be used
as a homework assignment, lab activity, or as the basis of an interactive
classroom activity. The twopart sequence Risk Assessment for Benton County,
Parts 1 and 2 has been used to introduce students to Excel in Hazards of the
Earth's Surface, an online service course at USF designed for nonmajors, for
the last two years.
Assessment
There is a slide at the end of the presentation that contains endofmodule questions. The endofmodule questions can be used to examine student understanding and learning gains from the module. The answer key for endofmodule questions is at the end of the instructor version of the module.
