The applet in this section allows you see how probabilities are determined from the exponential distribution. The user determines the mean of the distribution and the limits of probability. Three different probability expressions are available.

The focus of this curricular unit is twofold. The first is to consider the math classroom as a racialized space. In doing so, the unit will shed light on why math education is not race-neutral and will explain how color-blindness reinforces the oppression of students of color. The unit will examine how color-blindness within mathematics education ignores historical data and blames academic failure on students, their families, and their communities without recognizing the systemic biases that reproduce racial inequality through material stratification, deficiency framing, and reduced access to high quality instruction.

The second part of the unit will consider anti-racist teacher-centered instructional strategies that directly address inequality in math instruction. Among these strategies, the unit will consider teaching for understanding, group participation through complex instruction, culturally relevant pedagogy, and teaching mathematics for social justice. To achieve this, the unit will provide several examples of activities that approach mathematics instruction from a culturally relevant and critical lens. Then, the unit will examine a brief race-neutral Calculus lesson on integral approximation and will highlight components that reinforce systemic racism. Finally, the unit will then address what changes must be made within the sample lesson to better address issues pertaining to race in the math classroom.

A few PowerPoint or Keynote slides are used to set the historical context of the project and to introduce the general problem (see "Presentation Files" and "Instructors Notes" below). Bouncing a rubber ball in class from differing heights above the floor, and letting students see and hear the effects of differing travel times, helps students understand that longer travel time in a reflection experiment indicates a deeper reflector. The relevant parts of YouTube videos are shown (see links under "Other Materials" below). Have the students measure the time interval between the explosion and the impact a few times while showing the videos. One of the correspondents talks about (and attempts to show) how the bridge vibrated after the explosion.
Pass out the worksheet and the raw seismograms related to the Hoan demolition experiment. Then, with a copy of the seismograms projected onto the screen, hold an initial discussion of how to interpret the graphics: note the time scale, discuss what the different wave amplitudes mean, and so on. Then cluster into groups of 2-4 students and have each group try to "pick" the first arrivals of [1] the explosion-induced direct wave, [2] the impact-induced direct wave, and [3] the corresponding reflected waves. Depending on the type of students involved (intro non-geologists, intro geology/geophysics, geophysics), the teacher can provide more or less assistance in picking the arrivals of the direct and reflected waves.
Work through the quantitative material on the worksheet. Questions about how to handle uncertainty always occur, and if the students do not admit to having questions about this the teacher should ask them how they handle uncertainties. In a nutshell, the resultant uncertainty associated with the sum or difference in two numbers are the sum of the two uncertainties. For example, (23 Â 2) + (14 Â 1) = 37 Â 3. The resultant uncertainty associated with the product of two numbers can be estimated with the sum of the fractional (or percentage) uncertainties. For example, the percentage uncertainty of 23 Â 2 is (2/23) or 8.7% and the percentage uncertainty of 14 Â 1 is (1/14) or 7.1 %, so (23 Â 2) x (14 Â 1) = 322 Â 51 because (8.7% + 7.1%) = 15.8% and 15.8% of 322 is ~51. For a nice summary of simple uncertainty calculations, refer to http://spiff.rit.edu/classes/phys273/uncert/uncert.html or http://webpages.ursinus.edu/lriley/ref/unc/unc.html, or the statistics resources on the SERC website.
When the worksheets are completed, recap the experiment and compare the results with a map of crustal thicknesses for North America (e.g., Braile, 1989, Fig. 23B). Finally, it is nice to have the students evaluate the experience as homework.

In this activity, students will model a noisy set of bacterial cell count data using both exponential and logistic growth models. For each model the students will plot the data (or a linear transformation of the data) and apply the method of least squares to fit the model's parameters. Activities include both theoretical and conceptual work, exploring the properties of the differential equation models, as well as hands-on computational work, using spreadsheets to quickly process large amounts of data. This activity is meant as a capstone to the differential calculus portion of a typical undergraduate Calculus I course. It explores a biological application of a variety of differential calculus concepts, including: differential equations, numerical differentiation, optimization, and limits. Additional topics explored include semi-log plots and linear regression.

Today we're going to wrap up our discussion of General Linear Models (or GLMs) by taking a closer looking at two final common models: ANCOVA (Analysis of Covariance) and RMA (Repeated Measures ANOVA). We'll show you how additional variables, known has covariates can be used to reduce error, and show you how to tell if there's a difference between 2 or more groups or conditions. Between Regression, ANOVA, ANCOVA, and RMA you should have the tools necessary to better analyze both categorical and continuous data.

In this module, students calculate the pressure at the depth of compensation along a cross section of North America.

This lab activity has students use stream discharge data obtained from the USGS Water Resources Division web site in order to calculate recurrence intervals for a local stream. Using the recurrence data generated, the students then make recommendations to the residents of a local town as to what they might do to reduce their loss from the effects of frequent flooding in their community.

In this several week-long introductory geoscience project, students evaluate the potential for flooding in the local region. Students visit the site during the first week of the semester as part of a "Walk in the Watershed" and make observations in order to generate hypotheses about the processes that shape the landscape and control the movement of water. During a later lab period, students return to the same site to determine stream discharge using the flotation and current meter methods and compare and contrast the results from the two methods. In addition, students in the different laboratory sections use their data to compare and contrast reasons for why discharge may have changed over the course of the day or week during the following class meeting. As an in-class exercise, students examine an annual hydrograph and then predict the weather that generated the observed stream discharge. Students test their hypotheses by analyzing precipitation data available on-line in order to correlate flood events with storm types or other causes for major discharge events. Next, students examine historical flood and discharge data of the local stream available on-line at http://nwis.waterdata.usgs.gov/ as a homework assignment. In addition to calculating the recurrence interval and probability of occurrence for each event, students determine the discharge and stage of a 1-, 10-, 50-, and 100-year flood, create a rating curve, and generate a floodway map for each of these events. Subsequently, students revisit the site during lab and locate the boundaries of these flood events. Students will make recommendations for building a house in the region based on their analyses.

Students explore the USGS water website to identify the location of stream gauges on the Minnesota River and the types of data that can be retrieved from the website. They determine which data to download based on the area of interest in the exercise (St. Peter, MN) and import historical flood data into MS Excel. The students use a spreadsheet to rank each flood and calculate a recurrence interval for a given flood, then estimate the discharge and stage of the 100-year flood in St. Peter, MN. The final task is to establish a flood hazard zone on a topographic map of the city of St. Peter. Note: this exercise can be applied to almost any non-dammed river with two or more USGS gaging stations on it. Go to http://water.usgs.gov and select your state from the pull-down menu to view an interactive map of your state's rivers and gaging station locations.
