24 DISCIPLINARY EXAMPLES: Which math skills do students need in specific quantitative disciplines?
25
CATEGORIES OF MATH SKILLS NEEDED Arithmetic/Calculations/Number Sense Graphs Dimensional Analysis and Use of Symbols Linear and Simple Exponential Relationships Simple Algebra Problem Solving Statistics 25
26
BIOLOGY – SKILLS NEEDED Basic number sense – reasonableness of answers Graphing, especially starting from data and choosing axes and scale Dimensional Analysis Scientific notation, logarithms Simple algebra (such as Intro to Algebra or Elementary Algebra) Statistics
27
BIOLOGY SAMPLE PROBLEM 1.Choose a whale you want to draw, and find its maximum length in metric units. 2.Determine an optimum scale for your drawing to fit your paper, and show your calculations. 3.Calculate a conversion factor that allows you to translate the dimensions of the picture in the book into the sizes you should use in your drawing. Show your calculations.
28
CHEMISTRY – SKILLS NEEDED Order of operations, weighted averages, measuring volume Analysis of data and reasonableness of results Logarithms Algebra skills taught in Intro to Algebra Problem-solving skills Simple statistical concepts
29
CHEMISTRY SAMPLE PROBLEMS 1.Determine the volume of an object that has a mass of 455.6 g and a density of 19.3 g/ given that D = m/V. 2. Write the answer to the following calculation in scientific notation, using the correct number of significant figures: (433.621 – 333.9) x 11.900
30
GEOLOGY - SKILLS NEEDED Specializations have different needs, such as calculus for Geophysics; gradients for Meteorology General needs are: Graphing -- need to be able to start from data, not equations Rates of flow and averages
31
GEOLOGY SAMPLE PROBLEM A. From a local paper, find and record the following information for five consecutive days in an Excel spreadsheet: 1. High and low temperatures for the Dalles and Portland, converted into degrees Celsius. 2. Precipitation for both cities, converted into centimeters. B. Plot the information on two separate graphs, one for high/low temperatures, and the other for precipitation. Use a graphing program such as Excel, use titles for the graphs, and label the axes.
32
ECONOMICS – SKILLS NEEDED Expected value, weighted averages, index numbers Scatter plots and curve-fitting with technology Understand exponential growth Contextualized settings of the content Statistics Common sense interpretation The statistics taught in Math 105, Math in Society
33
ECONOMICS SAMPLE PROBLEM The following equations describe an economy (where quantities are in billions of dollars): C = 400 + 0.8Y D TA = 800 EX = 150 I = 100 TR = 500 + 0.05Y IM = 250 G = 480 Remember that Y D = Y – TA + TR and that in equilibrium Y = AE = C + I + G + EX – IM What is the equilibrium level of output (Y) for this economy? Show your work.
34
PHYSICS – SKILLS NEEDED Manipulate symbols without numbers in problems Use of units Problem-solving and critical thinking Applying simple math to solve problems Modeling – knowing which pieces of information to include or not Basic statistics
35
PHYSICS SAMPLE PROBLEM The final destination of a delivery truck is located 7.2 km in a direction 20 degrees South of West from its current position. If the truck travels 3.5 km due (directly) West, how far is it from its destination right now (straight line distance, “as the crow flies”)?
36
PSYCHOLOGY – SKILLS NEEDED Absolute value, percentage, basic arithmetic, rates of change Understand and use graphs, tables and charts Understand interactions of variables Independent vs. dependent variables Exponential vs. linear functions Middle school math Statistics Read and interpret; not necessarily calculate Understand correlation
37
PSYCHOLOGY SAMPLE PROBLEM To determine whether students would like more courses scheduled in the late afternoon and evening hours, 50 students selected at random from the 5,000 registered students were sent questionnaires. In this instance, the 5,000 students who are registered would be: a.A biased sample b.A population c.The dependent variable d.A representative sample
38
SOCIOLOGY – SKILLS NEEDED Creating and understanding graphs, slope, and intercepts Scientific notation, ratio and proportion Most of the algebra from Math 60 (Beginning Algebra) Mathematical modeling
39
SOCIOLOGY SAMPLE PROBLEM The 1936 Literary Digest presidential election poll predicted that Alf Landon would win the presidential election that year by a substantial majority. The poll was based on a sample of 2.4 million respondents drawn from three sources: 1) subscribers to the Literary Digest; 2) registered automobile owners; and 3) telephone users. Despite the poll’s prediction, Roosevelt beat Landon by a landslide. What might have gone wrong with the Literary Digest poll in this election?
40
NEXT STEPS Communicate with content area faculty Ensure students are aware of the best options for their career choices Become more aware of how math is applied in other content areas to develop appropriate pathways for students Incorporate content examples into everyday math work
41
CHALLENGES Sharing information from the February convening statewide Encouraging significant discussions that will lead to consensus within disciplines on the math skills needed for disciplines and career pathways Additional convening to dig deeper and include other disciplines?
42
Your thoughts?
