In 1892 The National Education Association formed
The Committee of Ten
The recommendations of the Committee of Ten... * 8 years of Elementary and 4 years of High School
* Reduce number of subjects to about 5
* Biology in 9th or 10th, Chemistry in 11th, and Physics in 12th
* Algebra in 9th grade, Geometry in 10th, Trigonometry in 12th
* All students should take a college prep curriculum Statistics Linear to Exponetial LARGE/small Numbers Normal Distribution Recursion Simulation and Probability Recursion Recursion Blood alcohol content or BAC is typically measured in mg of alcohol /ml of blood. Adults over 21 in most states will be arrested for DUI if they have more than 80 mg/ 100 ml or 0.08% BAC. Many handheld BAC meters like the AlcoHAWK Elite Digital by Breathalyzer and the Alco-Sensor III by Intoximeters give a readout to three decimal places. According to a Clinical Chemistry article, the standard deviation for a new Model 1000 Breathalyzer is 0.0037. Let’s say you are on a jury in which the defendant is charged for DUI and the BAC was measured to be exactly 0.080 which is the minimum amount necessary for a conviction.
a. What is the probability that the defendant would have a measured BAC of 0.080 or greater if
in fact the defendant’s actual BAC was 0.079?
b. What is the probability that the defendant would have a measured BAC of 0.080 or greater if
in fact the defendant’s actual BAC was 0.075?
c. What is the probability that the defendant would have a measured BAC of 0.080 or greater if
in fact the defendant’s actual BAC was 0.070?
d. Based on the evidence, describe whether you think it was safe for the defendant to be
driving. Explain. (If you weigh 160 lbs. and drink three 12 oz. beers in succession, your
BAC would be about 0.070)
e. Based on the evidence, describe whether you think the defendant should be found guilty of

TOPICS TO RECEIVE INCREASED ATTENTION
* The use of real-world problems to motivate and apply theory
* The use of computer utilities to develop conceptual understanding
* Computer-based methods such as successive approximations and graphing utilities for solving equations and inequalities
* The structure of number systems
* Matrices and their applications
* Integration across topics at all grade levels
* Coordinate and transformation approaches
* The development of short sequences of theorems
* Deductive arguments expressed orally and in sentence or paragraph form
* Computer-based explorations of 2-D and 3-D figures
* Three-dimensional geometry
* Real-world applications and modeling
* The use of appropriate scientific calculators
* Realistic applications and modeling
* Connections among the right triangle ratios, trigonometric functions, and circular functions
* The use of graphing utilities for solving equations and inequalities
* Integration across topics at all grade levels
* The connections among a problem situation, its model as a function in symbolic form, and the graph of that function
* Function equations expressed in standardized form as checks on the reasonableness of graphs produced by graphing utilities
* Functions that are constructed as models of real-world problems
DISCRETE MATHEMATICS High school drop outs Math "drop outs" What society has to say "The role of the cartoonist, as well as making us laugh at our shared predicament, is to discover and express what is repressed, and to say out loud what people everywhere are whispering".
