More Support for AP and Indirectly Newsweek's Rankings

Online cheating on graded school work is a real problem.  Sites like answers work very well for many assessments taken at home and at school.  Even math problems are solved online.  My more open students love to take an online class, they claim "[they] finish in a day, get an A.  What are friends for?"  With more and more students taking online courses, the irregularities in grading remain unresolved.

AP, IB, and Cambridge tests are proctored and are identical to all takers.  Their results have integrity, if not validity.  As a teacher who has offered courses from many online curriculum providers, I deeply know how believable an A or B is from an online course completed at home.  Zip.  It is what it is.

Taking an AP test is far, far better than taking an online assessment.  Newsweek and Jay Mathews have it right from the standpoint of a beneficiary of a school's rigor, which is what really matters.

Wolfram|Alpha and Online Math - A Wonderfully Unfortunate Fit

Wolfram|Alpha brings much of Mathematica to everyone.  It is a wonder of the 21st century, and it greatly helps doing math homework in Algebra, Algebra 2, Trig and more.  As a result, grades must be determined by classroom testing and work alone.  Online, distance learning in mathematics is more than compromised - it's obliterated, if grading with credit is an outcome.

Consider StudyIsland, one of the best online programs.  One student completed the entire course with an A in a matter of a few class periods by placing each question into WolframAlpha - every possible problem.  It takes far longer to type a problem such as Solve 3/(x+6) + 2/(x+1) = x/(x^2+7x+6) than to get the answer.  Copy the problem yourself, paste it into Wolfram|Alpha and see.  The plot is a bit funny, but the answer is clear.  Obviously, this would be grand for instruction, but not evaluation.

In short, teach online, but grade in class.  Perhaps regional centers for proctored exam taking with video cameras on students and their computer screens will be the next growth industry.

Costa Mesa High School Ranks in Top 6% of US Schools

Costa Mesa has joined Corona del Mar and Newport Harbor in the top 6% of US high schools according to Newsweek's easy-to-understand 2010 list based on Summer 2009 data.  CdM ranks in the top 1% and Harbor ranks in the top 3%.

For reference, Irvine's exceptional University High School is included in the chart below.  The lower the score, the better.  Only 1,600 schools out of 27,000 made the cut.


Jay Mathews, an education reporter for the Washington Post and Newsweek, developed the structure of the data.  However, the Newport-Mesa Summary, source of the chart above, is solely the responsibility of Dennis Ashendorf.

Thank You - DonorsChoose - Robots

The following thank you also outlines how a DonorsChoose grant can morph.

Dear Lisa, Michael, Joel, Vicki, Duane, Terry, Christine, Arnie, Maria, Mike, Kristian, George, Shelly, Sy and anonymous donors,

Finding the right level of robotics with programming for continuation students poses challenges. Without your support, the sweet spot wouldn't have been found. Furthermore, your commitment help makes our robot curriculum transferable to conventional schools which may enhance their students's destinations such as First Robotics or VEX. In the future, this effort may lead to summer internships in university labs; where masters of Python, Labview, Matlab, and JMP/Minitab software are in demand.

It would have been easy to start with LEGO Mindstorm robots which use a simplified Labview language. Our continuation students are familiar with LEGO's, but that's about it. None have assembled models or wired electronics. Our school's solar panel installation program would benefit from students who know the difference between open and closed circuits. Parallax Sumobots and BOE-bots provide the needed mechanical and electrical background at low cost. These robots have built-in breadboards that force students to install LED's and speakers, for example.

The tradeoff is that their BASIC software doesn't employ graphics, just text. Students would have to start by puzzling over code, which was an open question before the DonorsChoose grant was submitted. To mitigate this concern, a cardboard robot and several plastic analog robots, OWI Sumobots, "programmed" with variable resistors, were included in the grant. The cardboard robot died a quick death and the analog robots were inconsistent. Students didn't learn much. However the Parallax robots were simple to build and actually easy-to-program: students merely copied other programs and tweaked them to see how robots would respond to modified software. Fun and learning resulted. Showing off robot battles and robot travels impressed friends and teachers.

In the future, two or four students per math lab (3-5 per day) will work on a robotics/software/wiring curriculum. They will start with MIT's Scratch and Microsoft's Small Basic. Next they will work with MIT's Picocricket and inexpensive Parallax microcontroller breadboards. Finally, they will program and fight with the Parallax robots. As an option, they can either venture into greater depth with sensors on the Arrick Arobot platform or move into VEX robots.

None of this would have been possible without your help. You encouraged a few students today and many more at the start of next year. If you have questions, please contact me. Thank you for assisting DonorsChoose in its efforts to assist teachers directly. You made a difference.

With gratitude,
Mr. A

Math Software @ NCTM

Math software needs to be placed in perspective. One size does not fit all. Various objectives, including cost, must be considered. Please refer to this diagram for areas of concern.  At NCTM, several programs were on display. Comments on them and others follow. Text in Bold means that I will attempt to vet the products in 2010-2011.

Please realize that there are many free supplements.  Making them work cohesively with a curriculum, not just as an occasional time-filler, is the challenge.  It may be wiser to use Heymath, which is designed for teaching. On the other hand, through Lesson Study, combining Wolfram Demonstrations, Gizmos, Wolfram Alpha, VirtualNerd, Brightstorm, Autograph, and Geogebra with an online assessment system; such as Daskala, could yield remarkable results.

General Purpose

    Book Review - Mathematicians by Mariana Cook

    Each mathematician, accomplished, perhaps famous, has a full page photograph and a facing page containing a brief autobiography or statement.  It can be read in a few hours.

    Brandon Fradd, a Princeton math major, thought a photo book of Mathematicians would be well-received after seeing Scientists by Mariana Cook.  Good idea.  Her photographs are striking in black and white.  Most of the people were from Princeton (not a big surprise), but individuals from Oxford, Cambridge, Harvard, and a few New York and California schools also made the list - 92 professors in total.

    Each reader/viewer will respond differently to the brief personal essays.  Timothy Gowers (I have two of his works.) tries to relate his methods to research strategies, the practical rationality of his words shows a cool balance of thought, but Harold Kuhn's reference to all of his teachers by name and the sacrifices made by his parents and the role of chance in meeting people was too easy in which to relate. I cried while reading about him.  Of course, Andrew Wiles was photographed.  His humility, considering that he proved Fermat's Last Theorem - his childhood dream, was considerable.  William Thurston's text may have been the most important.  He stressed the pain of everyday public school instruction in math for himself, but he didn't allow it to kill his imagination.  He related how internal vision and analysis worked together: paragraphs suggesting the joyful magic in doing mathematics.

    And yes, the correlation between mathematicians and the love of music is highly positively correlated.

    Two Year Algebra - Reboot

    Struggling students can succeed in Algebra and complete high school.

    Approach
    • Organize a voluntary PLC of math teachers to pursue the pre-selected approach 
    • Consider looping for ninth-tenth grade.
    • Use a reform math text - dramatically different from the district's standard text
    • Grade Summative Assessments on a curve of highest eighth = A, offset quartiles = B,  C,  D.  If this is too drastic, then the PLC-advocated college grading scale of 75-100 is an A, 50-75 is a B, and 25-50 is a C may be appropriate.
    • Bottom eighth can earn a grade or pass by teachers's judgment or completion of alternative work such as ALEKS or StudyIsland or Algebra games like Dimension X/U or re-exam; even if semester has ended.
    • Bottom eighth cannot be determined until final for student motivation
    • Course starts with Assessment: Students scoring low that ALEKS Algebra Prep for Six Weeks
    • "Homework" completed in class as PRACTICE - careful attention paid to technique
    • Calculators used for most problems (some no calculator to mimic CST)
    • Supplements such as online formative assessment and/or Gizmos and/or Wolfram|Alpha or Akron.
    • Cultivate student growth mindset by using Brainology
    • Experiment with DimensionU online math video game.
    Possible Texts
    • Its About Time's Math Connections - not enough state standards may be an issue.
    • CPM - After 20 years, it now has state approval after changes - 1993 attack
    • Contract with Heymath! - other districts may have done this already.
    • Kinetic Books or NROC's new program, when available
    • Supplement current practice with a sequence of online manipulatives (eg Mathematica and Gizmos) coordinated with professional development and a PLC to determine sequence.
    Suggested Calculators
     Texts Review Status
    • More than one text can be selected depending on the number of teachers that volunteer and their interests.
    • CPM is used by 2-year Algebra programs where students alternate days of doing "homework" in class.  CPM claims that no supplementary materials are needed.  CPM, a non-profit, has an exceptionally low cost program:
      • August 2-6 - teacher training in Irvine at No Charge
      • Teacher text is $95 and each paperback, 3-hole punched, re-usable student text is $18
      • Classroom set of Algebra tiles is $97
      • 2" loose-leaf binder for text and notes: $1 in volume
    •  CPM has been used at Irvine's Northwood for six years.  In one-year classes, CST proficiency has increased from 30% to 80%.  In two-year classes, CST proficiency has increased from 6% to 24% and may be higher this year.  The main reason Irvine adopted CPM was to give their students a different look at Algebra from the standard texts.  CPM is also used by Northwood for Honors Geometry and Honors Algebra 2. I used CPM Geometry briefly at University High as a substitute.  The question quality was quite high.
    • Heymath! has asked us to proceed.  We would want to send them the Algebra AB pacing plan.  The Massachusetts and Connecticut experiences show this can be fruitful.
    • For Kinetic Books: To track student progress through the Algebra text and do online homework, you will want copies for the individual students. This would be the Class Set License, which is $49.95 per student.
    • Putting a Computer Lab License on some of the computers at school would allow them to do online homework while at school, but you wouldn’t be able to track their progress through the book itself.
    • Online homework is $10.00 per student. Given your situation, I’m not sure you would be doing that on a regular basis.
    • Given the above you have a few choices:
    1. If the Computer Lab License only, the students can use the text, but you don’t get any scoring information for them. 
    2. Use the Computer Lab License with online homework. With this you can track what the students do for homework that you assign. 
    3. Get Class Set Licenses for each of the students. This allows you to track their progress through the book and they can work at home. 
    4. The Class Set License plus online homework gives you the functionality tracking progress through the text as well as any homework you assign from the online homework system.
