  • And everything they need to know is in the book… but that’s not enough.
  • So, I don’t have to take the 3 face to face classes and instead just need one Redesign math class to be able to take college algebra
  • Yes, the 27 doctorates and 51 masters degrees will be outsmarted by the developmental math student because preparation doesn’t prepare you for everything!
  • Don’t forget to let people know about the change!

  • Reducing Remediation Through PartnershipsTed KoukounasAcademic Chair, Mathematics and ScienceAssociate Professor of Mathematics
  • Remedial Mathematics atSCCC๏ Two Remedial Mathematics Levels๏ Pre-Algebra๏ Algebra I๏ High percentage of High School students place in at least one of these courses.๏ Increase the time needed to complete their program๏ Increase likelihood of attrition
  • Developmental Course FactsPre-Algebra Algebra IEquivalent to 7th - 8th Grade Math in NY Equivalent to 9th - 10th Grade Math in NYNo Calculators Same concerns as Pre-Algebra +Students frustrated More abstractionFaculty frustrated More formulasResources are depleted More understanding Full time teaching load More critical thinking Coordination More linear and quadratic equation Release time More graphing Assessment More of “solve for x”
  • College Placement Tests๏ Inconsistent๏ Only a few major exams for such a big decision - CPT, ACT, etc.๏ Non -Standard definition of Remedial Mathematics and Non-Standard Placement Policies๏ “Instantaneous” placement that does not necessarily reflect TRUE knowledge
  • CPT/ SAT/ Regents๏ Piecewise function to Placing Students๏ Placement is “Okay” at Best๏ Local IE office for current data๏ More discussion๏ Another presentation
  • CPT Placement at SCCCCombined CPT Developmental Course Mathematics Course LevelArithmetic/Algebra Score<99 Pre-Algebra Developmental100-134 Algebra I Developmental>134 Varied as per program College Credit-Bearing requirements* Students with an 80 or greater on any Regents should not be placed into Pre-Algebra
  • Developmental MathPlacement at SCCC Semester N PercentFall 2006 5280 41.9%Fall 2007 5394 44.2%Fall 2008 5864 47.2%Fall 2009 6548 52.6%Fall 2010 6908 50.9%Fall 2011 6721 53.1%
  • Why so much remediation?๏ Lack of Knowledge๏ Lack of Preparedness๏ Time Lapse๏ Testing and Advising๏ Lack of student emphasis - Testing unreliable๏ Poor Coordination between HS and College regarding shared expectations
  • What can we do to helpstudents?๏ Students, teachers, and high school administrators need to know what happens to their students upon HS graduation๏ Inform the discussion๏ Work collectively๏ Better Alignment๏ SUNY- State University of New York Taskforce for Remediation
  • HS/ College Partnerships๏ Encourage the discussion๏ No Finger Pointing๏ Mutual Benefits๏ Curriculum Based๏ Guidance Counseling๏ Local Support Necessary๏ Everyone Wins!
  • College Commitment๏ Resources๏ Honesty and Transparency๏ Follow Through๏ Support - Time - Fiscal - Programmatic
  • HS Responsibilities๏ Receptive to discussions๏ Respond to action๏ Inform parents๏ Programmatic requirements๏ Fiscal support
  • Remediation Pilot๏ Substantive meetings - Make contact with the right personnel๏ Share mutual information - Honest comparisons - Shared expectations - State goals๏ Identify student deficiencies๏ Develop a remediation plan for students prior to college application
  • College Responsibilities๏ Up to date Institutional Data๏ FERPA Compliance๏ Confidentiality๏ Resources
  • Process Begins๏ Students requiring remediation identified in their junior year by an SCCC developed and HS administered Diagnostic Exam๏ If needed, students remediate at HS with the SCCC recommended curriculum during their senior year๏ CPT testing occurs after the remediation process๏ Review Pilot Results and make adjustments as necessary
  • Three-year studySemester RemedialFall 2010 66.7%Fall 2011 45.6%Fall 2012 31.1%
  • Who Benefits๏ Students๏ High School๏ College๏ Math Chairs and Deans๏ Faculty
  • Constraints๏ Not much is being done๏ Everyone is interested๏ Too much testing๏ Bottlenecking of resources๏ Faculty feel stretched - PARCC - Math Regents - Performance expectations
  • SUNY Remediation TaskForce๏ Reduce Remediation SUNY-wide๏ Inform Discussion๏ Make Recommendations - A Stronger Education Pipeline that Reduces the Need for Developmental Education - Stronger Remediation Practices - More Effective State Funding Policy
  • Thank You!๏ Continue the Discussion๏ Discuss options for helping local school districts deal with remediation at HS๏ Familiarize yourself with the data from your constituents๏ Contact me for more details๏ Ted Koukounas, koukout@sunysuffolk.edu 631-548-2670

  • One class = $5,000 savings
  • What Not to do in aDevelopmentalMath RedesignErin CookeGwinnett Technical College, GA
  • “Redesign is self-paced…”๏ Students hear “Nothing has to be done today!”๏ Students make everything with a due date (and some without) a higher priority
  • Results๏ Students save most of the work until the last few weeks of the semester๏ Some miracles will happen - students will do 12 weeks of work in 3 weeks๏ Many students do not complete the course
  • Instead…๏ Have a pacing guide with due dates๏ Give students due date sheets they fill in๏ Give a penalty for missing due dates๏ Remind students that they can work ahead and cheer them on!
  • “The instructors are on thesame page - I sent the email.”๏ No, really, they are not๏ Just because an email has “everything” the instructors needed does not mean they are trained๏ Only the person who wrote the syllabus finds the syllabus interesting
  • Results๏ Faculty feel lost, uninformed๏ Students get misinformation and inherit the lost feeling๏ Redesign satisfaction may decline because it feels “undirected”๏ Faculty acquire more pigment-challenged follicles
  • Instead๏ Let the faculty experience a module!๏ Put the course materials in a course - Syllabus - First day of class PowerPoint - Student handouts - Summary sheet of Redesign๏ Put a quiz at the end of the materials and require 100% from all math faculty
  • “Everything the students needis in the syllabus”๏ Syllabi can be confusing๏ If instructors do not like reading the syllabus, most students will not either
  • Result๏ Students are unsure about what is expected of them๏ There may be many “Well, can I…? What about…?” questions from students๏ Worse than many questions is no questions!
  • Instead๏ Give the key points in as many ways as possible - PowerPoints - Handouts (think colorful and hole punched) - Email - Signs in the room๏ Flow charts are great!
  • “Students are fine - I haven’tgotten any questions.”๏ Students know there was a lot of information on the first day - Students feel they should already know everything๏ Mimicking classmates does not necessarily mean they are doing the right things.
  • Result๏ Students work on the wrong assignments๏ Do not know proper protocol for the class – attendance, notes, testing, etc.๏ Students quit attending class or withdraw
  • Instead๏ Keep an eye on students via the gradebook๏ Send supportive emails and encourage them to ask questions๏ Tell students in class to check their email๏ Remind the class this is new and is it perfectly normal to feel uncertain.
  • “Redesign is on - so advisorsand students know about it.”๏ Knowing of Redesign is much different than knowing about Redesign๏ There will be many students who do not know why they are attending lecture in a computer lab๏ Advisors may have incorrect information
  • Result๏ Students and advisors are hesitant about Redesign and will search for F2F alternatives๏ Students may be told they have a faster path than they do
  • Instead๏ Change the name of the course to include Redesign๏ Have a link to a video explaining (briefly) about Redesign๏ Inform administration about Redesign
  • “We’re set! All our bases arecovered!”๏ Welcome to education! (you must be new)๏ Students are creative and will work hard to think of something that the entire department did not think about or plan for
  • Result๏ There will be periods of chaos for instructors and students๏ The program looks unorganized or unplanned๏ Happy hour sales at local pubs and restaurants go up
  • Instead๏ Know that new situations are possible๏ Decide who needs to be involved in “immediate” policy decisions๏ Have those people on speed dial and in one email contact
  • The most important parts?๏ Keep a positive attitude, roll with the punches and do not utter the words “self- paced”๏ No time for questions, but feel free to applaud, whistle and cheer wildly! (or sit and smile quietly) Thank you!!

  • “If you do the homework, you won’t have to study. Doing the homework IS my studying.”
  • “Even if it makes the tutor mad, just keep telling them to go over and over it because you HAVE to get it.”
  • “Though this does take a lot of time, I have made myself sample tests. I make sure to put problems I struggle with on the sample test.”๏ the sample test.”
  • “If you miss class, it’s your job to find out what you missed. The teacher’s not going to want to re-teach the work and your friends may not want to help you either.”
  • “I paid attention a lot in class. I think that’s the key.”
  • “If you miss a day, you miss a lot. Messing up one time will mess you up throughout because everything’s connected in Math.”
  • “I sit in front on purpose. I never sit in the back of the room because that’s where all the chitter-chatter is.”
  • “You have to come to class and that’s as simple as it is. Just get up and come… sleep ain’t that precious.”
  • “Me personally, I always came to class, but I always came late. You would think 5-10 minutes is nothing but that 5-10 minutes always put me so far behind.”
  • “Do your homework when you’re supposed to do it and not at 3 o’clock in the morning, the night before it’s due.”
  • “Ask questions even if you’re the only one asking them. You never know if someone else has that same question.”
  • “Come in with an open mind and leave your old feelings behind. These teachers really want to help you.”
  • “You’ve got to DO the problems, not just look at them. Because just seeing it, you won’t remember how to do it. Happened to me a lot… mm, mm, mm.”
  • “I noticed my friend was getting better grades than me so I would get her to help me.”
  • “Think about what you want to become in life and use that to press yourself.”
  • “Make sure you get a professor who explains things well. That helps a lot.”
  • “To face your challenges would be a nice self-accomplishment. Also you’ll be able to help others in the future.”

  • Numerical FulcrumsA Mathematical Exploration from Prealgebra to Post-Calculus Richard Zucker Irvine Valley College
  • What is a Numerical Center? 204 is the Numerical Center of the list 1 to 288.
  • A number is the Numerical Centerof a list of consecutive naturalnumbers starting at 1 if it separatesthe list into two groups that have thesame sum.6 is the Numerical Center of the list 1 to 8.
  • Is every number a Numerical Center? No, not 5.
  • 35 is the Numerical Center of the list 1 to 49. 595 = 595
  • Is 1 a Numerical Center? ? = ? Arguably, yes.
  • Numerical Centers are likeburied treasure. Students ofall abilities can experience thethrill of discovery!
  • Can you find other NumericalCenters?1, 6, 35, 204, 1189, 6930, 40391, …Is there a pattern? There is a recursion relation, but I’ll let you find it.
  • One of my students was thrilled to discover this recurrence relation that depends only on the one prior number in the sequence: 2 2Cn 1 17 C n 1 6C n 1 1 8 Cn 1
  • Is there a general formula that predicts the n th Numerical Center?Several of my students derived the generalformula by studying Binet’s formula for Fibonaccinumbers. n n 1 5 1 5 Binet’s Fn 2 n 5 Formula: Numerical Cn ????????? Center Formula:
  • Do Numerical Centers have anyinteresting properties? Their squares are also triangular numbers. 6 8
  • This shopping center is in Costa Mesa, CA, not far from Irvine Valley College.
  • A Numerical Fulcrum is similar to aNumerical Center, but the list ofconsecutive natural numbersdoesn’t have to start with 1. 14 is a Numerical Fulcrum for the list {4, 5, …, 19}.
  • 9 is a Numerical Fulcrum for two lists!
  • R.J. Liljestrom (my student in 2002) discovered and proveda significant theorem about Numerical Fulcrums: F is not a Numerical Fulcrum if and only if 4F2 + 1 is prime. For example: • Since 101 = 4(52) + 1 is prime, then 5 is not a Numerical Fulcrum. • Since 9 is a Numerical Fulcrum, then 4(92) + 1 = 325 is composite.

  • Why is R.J.’s theorem significant?In 1912 at the International Congress ofMathematicians, Edmund Landau asked fourquestions about prime numbers. His fourthquestion was, “Are there infinitely many primesof the form n2 + 1?”One hundred years later, the question is stillunresolved.Because of R.J.’s theorem, Landau’s questionis equivalent to asking, “Are there infinitelymany natural numbers that are not NumericalFulcrums?”
