Oil leaked from April 20 July 15, 2010.
On July 15, the leak was stopped after releasing about 4.9 million barrels (7.8105 m3) of crude oil.
It was estimated that 53,000 barrels per day (8,400 m3/d) were escaping from the well just before it was capped.
It is believed that the daily flow rate diminished over time, starting at about 62,000 barrels per day (9,900 m3/d) and decreasing as the reservoir of hydrocarbons feeding the gusher was gradually depleted.
The Deepwater Horizon was able to operate in waters up to 8,000 feet (2,400 m) deep and drill down to 30,000 feet (9,100 m).
BP estimated the worst case flow at 162,000 barrels per day (25,800 m3/d).
Internal BP documents estimated the flow could be as much as 100,000 barrels per day (16,000 m3/d).

Deepwater Horizon Oil Spill
  • What I wonder questions about the mathematics
    would kids (or adults) ask?
  • What jobs related to the spill involve pertinent
    mathematics?
  • To which mathematics content could this disaster
    be connected?

5
Highlighted SOL Changes
  • Awareness (curriculum and pacing guides, SOL
    Crosswalks, VDOE training institutes)
  • Understanding
  • Content (Curriculum Framework, technical
    assistance documents)
  • Connections (Enhanced Scope and Sequence lesson,
    vertical articulation of content)

Each figure in the pattern below is made of
hexagons that measure 1 centimeter on each side.
NAEP Released Items 2007 Grade 8 M7 14 SCR
Hard 29
If the pattern of adding one hexagon to each
figure is continued, what will be the perimeter
of the 25th figure in the pattern? Show how you
found your answer.
15
Perimeter Problem
  • In what situation would this task be used?
  • In which course/level would you use this task?
  • How would you adjust it for another course/level?

16
Worthwhile task?Questions to ask yourself
  • Does the problem challenge students to use
    higher-level critical thinking skills?
  • Is the problem clearly connected to the targeted
    mathematics?
  • Are there multiple ways to solve this problem?
  • Is it accessible to all students?

17
Worthwhile task?Questions to ask yourself
  • Does the problem promote mathematical
    communication?
  • What might students struggle with?
  • This would be an appropriate problem if you were
    studying or if you have already studied

18
Where can I get worthwhile mathematical tasks?
  • NAEP released items http//nces.ed.gov/nationsrepo

  • PISA released items http//nces.ed.gov/surveys/pis
    a/educators.asp
  • APEC Mathematics Assessment Database

Assessing Higher-level Thinking Skills
8.11The student will solve practical area and
perimeter problems involving composite plane
figures.
Find the area of the shaded region.

Assessing Higher-level Thinking Skills
8.5 b) The student will find the two consecutive
whole numbers between which a square root lies.
Between which two square roots does 5 lie?
FUTURE

21
Assessing Higher-level Thinking Skills
A.10 The student will compare and contrast
multiple univariate data sets, using
box-and-whisker plots.
22
Assessing Higher-level Thinking Skills
  • Increased levels of complexity in analysis
  • Increased levels of complexity in expressions and
    equations
  • Comparing and contrasting of functions during
    analysis

23
New SOL Blueprints
  • Mega-categories combine reporting categories
  • Grade 6 from 5 to 4
  • Grade 7-8 from 5 to 3
  • Algebra I from 4 to 3
  • Geometry and Algebra II from 5 to 3

24
Note Asterisk indicates that the SOL will be
assessed in the non-calculator section.

New Formula Sheets
26
Technology Enhanced Items
  • Interactive questions
  • Hot-spots
  • Drag and drop
  • Creation of graphs
  • Short response
  • Practice ePAT available by February 2011

Beginning in Spring 2011
27
New SOL Assessment Timeline
  • Spring 2011
  • All SOL tests (live test items) based on 2001 SOL
  • Field test items will be based on the 2009 SOL
  • Technology enhanced items will be field tested in
    grades 6-8 and EOC SOL tests

28
New SOL Assessment Timeline
  • Fall 2011
  • EOC SOL tests will be based on 2009 SOL
  • Spring 2012
  • All SOL tests will be based on 2009 SOL

29
What is our goal as teachers of mathematics?
  • What will tomorrows jobs look like?
  • Teach kids how to use their critical thinking and
    reasoning skills to adapt and overcome in
    unfamiliar settings
