Reforming Developmental Math, A Data
Driven Approach:
Perspectives from Dyscalculia, to curriculum, to
pedagogy; using what works (a preliminary report)
Developmental Math has been called the
“Bridge to Nowhere”
WHY?
The national average for the passing rate of a developmental math
course is about 50%. If a student has to take two developmental
math courses. Then only 50% X 50% = 25% ever make it to a
college level math course, and only a fraction of those 25% ever
pass a college level math course!
This is a national problem that colleges across the country have
been trying to find a solution for. It is truly a multi-billion dollar
problem, not to mention the costs to a student's self-esteem.
Accelerating Remedial Math Education (Fast Start)
Housatonic Community College, an Achieving the Dream college in Connecticut, is piloting a self-paced, modularized, competency-based, developmental math course. The course is offered in a lab setting, with open entry and exit so that students can start and finish their coursework at their own pace. State and institutional leaders are looking for ways to overcome obstacles that HCC has encountered in overcoming financial aid and other policy constraints, even as the college is trying to expand this program model more broadly across the institution.
Community College of Denver has developed “Fast Start,” a developmental education design that enables students to take modules of two different courses in the same semester. This accelerates their progress through both a traditional class setting and a self-paced option. State system policies around managing enrollment data have made it easier for CCD to offer this option.
Mountain Empire Community College, an Achieving the Dream College in Virginia, has developed short refresher courses for developmental math students. These courses take less time to complete and cost the student less than more traditional developmental courses. Students can move through more than one of the short courses in a single semester. As in Denver, Virginia’s enrollment, financial aid, and student data system policies have not presented any obstacle to Mountain Empire’s innovations.

Florida colleges to drop remedial
classes for thousands
By Denise-Marie Ordway, Orlando Sentinel For years, men and women wanting to take classes at their local community colleges have been discouraged to learn they must complete a remedial program before enrolling in college-level courses.
...
Now, amid an outcry for nationwide reforms in remedial education, Florida lawmakers have
ordered a complete overhaul of the state's college remedial programs.
...
Starting in 2014, a large segment of students will be able to immediately enroll in college-level courses, regardless of their academic abilities. They will not have to take remedial courses or even a placement test, which is required by community colleges to detect gaps in learning.

Why Is Florida Ending Remedial
Education for College Students?
Starting this fall, academically
underprepared students at Florida's public universities no longer have to take classes
designed to help them catch up.
By Janell Ross
August 25, 2014 Back when remedial education was popular in policy circles, it was seen as a way to help those students most at risk of
dropping out of college. Instead of immediately finding themselves overwhelmed after arriving at college academically underprepared, students could get up to speed through remedial courses offered side-by-side with traditional college
classes. In the last few years, however, critics have begun to question whether remedial
classes solved any problems or instead created more of their own, as the share of students
required to spend valuable financial-aid funds and time on zero-credit courses that brought them no closer to a degree expanded.

Key factors driving their degree of success: Small classes (limited to 24 students, but typically only half that number enroll.) A student focused teaching pedagogy. They spend a lot of time on the non-cognitive aspects of engaging the students.
Statway/Quantway: The Carnegie Foundation has created an alternative (non-Algebraic)
approach for servicing developmental math students. For $25k per year your institution can join a consortium of other institutions, but you must use at least 80% of their material and follow their guidelines. Currently claims to have around 33 Institutions on board. Suffolk is considering paying $50k for a two year commitment, plus expenses associated with sending 5 potential instructors to California to be trained. Quantway boasts a 56% pass rate for first time developmental students. Currently Suffolk has first time pass rates of 56.1% for MAT001 and 62.9% for MAT007.
California State Universities transforming course design for developmental mathematics. The wide variety of contexts amongst the various campuses in the CSU system prohibits a “one size fits all” approach to developmental mathematics course redesign. Because of this, the CSU Transforming Course Design teams have opted not to recommend a single redesign approach, but rather to construct a “menu” of course redesign components from which faculty at any given campus can select various components of redesign that are appropriate for their particular student needs and campus resources.
1. Diagnostic and Placement Tests 2. Early Start Programs
3. Alternative instructional strategies A. Mastery Learning
B. Redesigning Instructional Strategies - Online Technology C. Supplemental Instruction
D. Alternate Course Designs for Specific Cohorts 4. Integrating Technology in Teaching Techniques
North Carolina Community Colleges began offering developmental math courses in the
Fall of 2013 as four-week course modules with each module worth one credit hour in four weeks. The number of course modules a student will need will be determined by the college level math course required by the student's degree program or major.
Illinois Community Colleges improves their developmental math. Guiding principles for any developmental math program
● Institute high levels of organization for the program in terms of consistent content, pace,
instruction, and expectations.
● Establish program assessment measures that are used and evaluated regularly to
gauge program effectiveness and possible areas of improvement.
● Assess persistence, retention, and performance of students in subsequent courses.
● Use results to improve the program.
● Create structures and support for adjunct faculty such as materials, training, mentoring,
and professional development.
Goals for each facet of the developmental math program
● Placement: Refine testing, placement and administrative procedures to ensure that
students enroll in the developmental courses [and/or programs] they need.
● Advising: Assist students to enter and succeed in the courses and programs that best
meet their needs.
● Courses: Improve and diversify course offerings to support diverse ability levels,
learning styles, and goals.
● Instruction: Provide quality instruction that fosters student engagement and learning.
● Support: Establish multiple and varied means to support students through the program.

Cleveland State Community College is redesigning its developmental math program, which consists of three courses: Basic Math, Elementary Algebra and Intermediate Algebra. These courses have historically been offered primarily in a traditional lecture format, enrolling over 1200 students annually with ~200 students in Basic Math, ~500 students in Elementary Algebra, and ~500 students in Intermediate Algebra. Drop-Failure-Withdrawal (DFW) rates have averaged 45% in these courses. Elementary Algebra has presented the biggest obstacle to student success, often having DFW rates of more than 50%.
Cleveland State has redesigned these three math courses using the Emporium Model pioneered at Virginia Tech and replicated at many additional institutions. At CSCC, students meet one hour in class and two hours in a large computer lab. The one-hour class meetings are held in small labs (20 computers). Instructors do not lecture during class meetings. Instead, students work online and instructors help students
individually. Instructors also review student progress and help students with their
action plans for the coming week.
Prior to the redesign, an average of 55% of students taking any developmental math
course at Cleveland State earned a final grade of A. B or C. After the redesign during
fall 2008, 72% earned an A, B or C, which represents a 31% increase in course
completion rates.

A Common Thread: All the reforms that focused on the students, making the students understand that they mattered and that the teachers would check up on the student and their progress throughout the process, and explored ways to motivate the students, including peer-to-peer teaching, showed the greatest levels of success.
The first, and most important, reason for success is Student Engagement. “The primary reason many students do not succeed in developmental math courses is that they do not actually do the problems. As a population, they generally do not spend enough time with the material, and this is why they fail at a very high rate.”
The Non-Cognitive aspects were the most important piece for
student success!

● the courses, how they were delivered, and what they taught
● student diagnostics and placement

Special thanks to the Office of Institutional Effectiveness for providing us with the data in an expeditious manner
Our analysis looked at developmental math students from the Fall of 2010 to the Spring of 2014. There were a total of 33,832 developmental students (actually 21,641 unique students) included in this study. We also looked at historical data from 1988-1992 (8,536 unique students)
The overall persistence rate (the rate at which students move on to a college level math course) is quite low. Only 37% of developmental students move on to take a college level math course, with only 25% of the original number passing that course with a D, and 19% passing with a C or better. There is a significant difference between MAT001 and MAT007 with persistence, passing and success rates of 19%, 13%, 10% for MAT001 and 43%, 31%, 25% for MAT007. There is also a fairly significant difference between the lecture and the lab with the data favoring the lecture over the lab. This is a huge opportunity for the college. We lost 62% of the 21,641 or 13,405 students in this 4 ½ year study, as they never went on to take a college level math course. We need to find a better way to meet the needs of these students and provide them with a plan for their
future. The fact that ONLY 10% of our MAT001 students will eventually succeed (C or

Providing the Right Content
Developmental math means many things to many instructors. Currently we lack a coordinated, consistent, and well-defined set of course content topics for our developmental courses. We have departmental syllabi for MAT001, MAT006, and MAT007, but the level at which to teach a particular topic is often not precisely spelled out. This is fine for the upper level courses, to an extent, but for the developmental courses this can be very problematic.
There should be NO ambiguity in what should be taught, and at what level, in a developmental course. This isn't an issue for the MALA sections of the course, since the material is limited by ALEKS, and the tests are standardized. This, however, is not the case for the lecture courses, which are highly dependent upon the textbook.
We need to reach a consensus on exactly what we should teach these students and to what level of mastery. Since NYS has adopted common core*, we propose aligning what we teach with common core, but at the same time tailoring it to the needs of college students taking developmental math.
The courses need to satisfy two types of students, one that takes either MAT101, or MAT102 (liberal arts students), and one that takes either MAT103, or MAT111 (students who require more mathematics training based upon their chosen major)
Providing the Right Content (cont.)
One of the most successful models on what to teach, and at what level, is the Singapore
Mathematics Curriculum and its associated textbooks. The textbook is actually more
important than the stated curriculum, since it alone defines what is taught.
Singapore Math has found a successful blend of Number, Algebra, Geometry, Measurement Systems, Statistics and Probability concepts, needed by all students, but taught at the proper level and not too fast. They redesigned their curriculum around Quality and not Quantity, and their textbooks reflected it.*

Where should we place our developmental students?
Delivering the Best Pedagogy
While proper course content is required to set limits and expectations, proper pedagogy is more critical for a student's success.
Proper pedagogy has two important aspects; Cognitive, where you focus on how to
teach a concept in the “best” way, and Non-Cognitive, where the focus is on
engaging and motivating the student to put the necessary effort in to succeed.
In all the attempts by other colleges to address the developmental math problem, it is the non-cognitive aspects of pedagogy that has proven to have the largest impact on student success.
The most successful attempts at getting developmental students to succeed, were the ones that were able to successfully connect to the students, so that the student's can and do control their own learning. This is the most critical component for the “at-risk” student's. It is also the primary reason that the students succeed in their subsequent courses (not just math).
The real question then, is how to standardize this in all developmental courses. This should not be teacher nor course dependent, since it is so critical.
● Have only one developmental math course that a student needs to take before moving on
to a college level course. A student can take either MAT006 or MAT007 depending upon their level of preparedness. Remove the multiplication rule for loosing students: (50% pass MAT001) X (50% Pass MAT007) = 25% available to take a College Level Math
● Have different “tracks” of MAT006 and MAT007 based upon student capabilities, with the
lower “track” courses having fewer students and a teacher (or student) aide assigned to the class. By “track” we mean the same material, but we separate the higher risk students from the lower risk students, and give the higher risk students more individualized and customized instruction to help them succeed. This requires proper placement of students which could come from Accuplacer or DyscalculiUM Screener (we're testing it this semester).
● Define the precise goals/objectives of MAT006 and MAT007. For example, “prepare a
student to take either MAT101, MAT102, MAT103, MAT111, or a science class. However,
a grade of SB or higher is required for MAT103 or higher and for certain science classes.”
Proposed Holistic Solution
Ideas to Discuss and Debate
● Revise the syllabi for MAT006 and MAT007, based upon the course definitions mentioned
above (choose the precise topics and define the level of mastery for each). Revise along the lines of Common Core (the Singapore version), since this is what is currently being taught in high school. Modify topics to meet the specific needs of the 99% of developmental student not planning on going into STEM. NOTE: The course content of MAT006 and MAT007 have not changed in over 40 years, but the secondary school curriculum has undergone numerous sweeping changes over that time period. They are long overdue for a major revision.
● Come up with “best practices” for teaching all the topics in the newly defined MAT006 and
MAT007 courses and share with all faculty teaching the courses.
● Develop special training for faculty to properly teach developmental students. Perhaps
only certain (certified?) faculty should be allowed to teach the lower track courses with the highest risk students. Include non-cognitive approaches.

The Five Non-Cognitive Skills
In their review of the existing research, the University of Chicago scholars identify
five non-cognitive skills that contribute to students’ academic success. They are:
•
Academic Behaviors
– observable behaviors that show students’ engagement
and effort
•
Academic Mindsets
- students’ attitudes and beliefs about their academic
work and ability
•
Academic Perseverance
– the ability to overcome distractions, obstacles and
challenges to complete academic work
•
Learning Strategies
– tactics that students use to help them remember, think
and learn
•
Social Skills
– behaviors that allow students to interact with peers and adults in
positive and productive ways

Dyscalculia
What it is, and how best to teach a
dyscalculic.
Dyscalculia
Also called “number blindness,” is severe difficulty in making arithmetical calculations, as a result of a brain disorder. It affects 3-6% of the general population.
Dyscalculia is a specific learning disability that affects a person’s ability to acquire arithmetical skills. It can manifest itself as a person’s inability to understand basic number concepts and/or number relationships, recognize symbols, and comprehend quantitative and spatial information. Many people liken the effects of dyscalculia with numbers to that of dyslexia with words, and while there are many characteristics that overlap, however, there is no proven link between the two
Screening for Dyscalculia
DysCalculiUM is the first web-based solution for screening for dyscalculia in adults and learners in post secondary education. It is effective in both further and higher education, but can also be used to screen adults in the workplace who are struggling with mathematics.
