Oil SpillAn oil spill breaks up over the sea in smaller and larger sections. An aerial photograph is taken of the area and it is estimated that the sections of oil and open water can be enclosed by a 4 by 5 kilometer rectangle.Oil Spill Picture

Oil Spill SolutionProbability and RatiosMonte Carlo MethodThe photo is digitized and fed into a computer, then random points are programmed and noted whether they hit the sought area. The greater the total number of points the more reliable the estimate.Pulse RateDo you see any patterns in this chart?

Turkey TimeA turkey is taken from the refrigerator at 2C and placed in an oven preheated to 200C and kept at that temperature; after 30 minutes the internal temperature of the turkey has risen to 16C. The fowl is ready to be taken out when it internal temperature reaches 88C.Determine the cooking time required.Turkey Time SolutionCalculus, Science of Heat Transfer

What these problems tell usWe look for solutions to problems from what we knowSkill development doesnt automatically lead to mathematical thinkingHistory brings a new perspective to mathMathematical modeling connects math to lifeCurrent Math ProgressionTerminal Math Courses For non-STEM majorsAddition for STEM Math PathMath PresentersJohn Squires Chattanooga State CCBetty Frost Jackson State CCMyra Snell Los Medanos CCAmy Getz/ Uri Treisman UT AustinTristan Denley Austin Peay Stat UniversityFrom Myra Snells presentationFor students placing two levels below a college course in English/Math, there are 5 exit points where they fall away:

Do they pass the first course? If they pass, do they enroll in the next course? If they enroll, do they pass the second course?If they pass, do they enroll in the college-level course? If they enroll, do they pass the college-level course?

Students placing three levels down have 7 exit points.
