Problem With Measurements


During the last few years the Mantra has been "we have to measure". As a result we at Rio have started measuring various easily measured metrics.
In my opinion we have never discussed "what should be measured?"
Did we ever have a discussion on what we should be measuring? Some would argue yes.
However, this affirmative answer is misleading.  The conveniently collected numbers are more popular and tend to dominate the data generated.

Redefining Community College Success - Inside Higher Ed

Redefining Community College Success - Inside Higher Ed
Many people forget that, how we measure, and what we decide to measure, determines the results. Here is an excellent article about behind the scene debate.

Solving Two Out of Three Problems with SLO

As promised here is the post on why “S” in SLO stands for Spurious, the “L” stands for Loathsome, and the “O” stands for Odious.

Let us start with the biggest problem with SLO the Spuriousness of the data. The standard methodology in statistic is when collecting data for comparison a single set of data should be collected. One should not compare apples to oranges. The current SLO assessment allows each instructor or group of instructor to decide how to measure the outcome. Depending on how it is measured and who is doing the measuring you will come up with different results. The only way around this problem is to standardize the outcome and the assessment tool. This works well when assessing outcomes in the vocational fields such as nursing and auto technology where the outcomes have concrete results. However, it does not work in fields where there is disagreement about the conclusion of the study. Example from economics include should taxes be raised or lowered. The answer to this question depends on your perspective. If you are a long-run thinker you will concentrate on the deficit and debt left behind which will hamper growth. If you are a short-run thinker you will concentrate on creating jobs to pay the bills. The choice depends on your current position and your personality. One can argue that we can write an outcome that measures this exact point. (if you continue reading you will see that faculty are already doing this!)

But how will we assess this point when emotions are involved. How useful are such assessments? Did the student miss the question because they could not separate their personal beliefs from what was being studied in a rational manner versus they did not get the concept completely. We could break the question down to study it at the granular level but then this can not be done in a simple manner. I as Economics instructor when assessing students to assign grades go through this process. (I told you we the faculty are already assessing our students!) Basically the faculty are being asked to duplicate their work and this leads to the “L” in SLO which stands for Loathsome. It is loathsome in that we are forced to duplicate our assessment and take time away from instruction.

The Administrators and non-experts in order to make the process less Loathsome for the bureaucracy and easier for the non-experts to understand the data we are asked to measure uses a simple assessment tool with Satisfactory/Unsatisfactory. So ease of Data collection and tabulation for bureaucrats leads to more work for the instructor and worst unreliable data. (Basically they are asking us to enter useless data so they can have another form that collects dust!)

Another field the assessment can be counterproductive is in fields where creativity is valued. Creativity and standardization are two different things. So Standardization which kills creativity leads to the “O” in SLO which stands for Odious. How are we to standardize our students’ tastes?

The only way around these problems, with the exception of creativity (The Odious Problem), is to adopt standardized tests created by a panel of experts and use them when assigning grades. If we are going to do this right lets Standardize the assessment. Basically, our grades and assessment scores will be one and the same. This solution is still odious due to the problem of Academic freedom. But the people who work in the intellectual gutters of universities, better known as Schools of Education, will come up with some other bright idea to solve this problem of academic freedom. I will confess that I am willing to teach to some standardized test such as CLEP instead of wasting my time reinventing the wheel by creating new questions, and wasting more time assessing students twice. The current set up asks the instructor to assess once for the grades they assign and once for the purposes of SLO. Next the current system asks us to waste even more time discussing it with other faculty who may or may not be in our field. These discussions usually lead to changing the assessment questions which leads to the problem comparing two different sets of data across time. This is basically comparing data for apples in one year to data for oranges in another.

I think the biggest obstacle to having a standardized test will be the Administration and K-12 teachers. Administrators will not like these standardized tests because they will see all of the students who will fail these standardized tests, thereby causing enrollment to fall and graduation rates falling as fewer students pass college level courses. The K-12 teachers will fear these tests because it will highlight the fact that our high schools are passing and graduating students who are not prepared for college.

In conclusion, if we are truly serious about SLO in the Social Sciences we should just buy the tests from CLEP for various disciplines (click here for a list of classes we can standardize) and use them to determine our students’ grades. We as faculty will teach to these tests and at the end of the semester our discussion will be based on truly reliable data, and not a waste of time discussing something spurious.

Buddhism and SLO


Please be patient with me as I retell a Buddhist creation myth from memory that I read in an old book.
There is a Buddhist creation myth that long long ago humans were composed entirely of light without bodies. We floated around and lived forever. One day our ancestors saw a beautiful dew form on a blade of grass, and could not resist coming down to look at it. As they came down they saw every blade of grass had a similar dew forming on them. One of the spirit decided to taste the cool refreshing dew. It was wonderful. Other spirits followed licking the blades of grass. As they did this they started to gain physical forms and found themselves with an appetite for other food. As they ate they started to produce human waste which lead to something new "disease", suffering and death.
On Flex day I heard some faculty talk of how the SLOs will help us to improve our teaching and the discussions we can have about the data. As I heard this I remembered the above story. How beautiful ideas can create waste as they get implemented. How the beautiful idea of learning and collaboration quickly turns into the disease of incrimination and punishment as spurious (false) data is compared. Also we have to waste resources on new bureaucracy to track these false data.
Yes the data is Spurious! Actually that is what the "S" in SLO stands for..
I will write more about that in the future.

My Weekend Reading


This weekend I realized that I hate long weekends. No school Monday and I am going crazy. I started reading various economics blogs which linked out. One story was about Gisele Bundchen wanting to remain the world's richest model and is insisting that she be paid in almost any currency but the U.S. dollar. This story made me think about how I wish I could be paid in Euro$.
Another story that caught my eyes was from Forbes about prediction market software. As the story points out most businesses and organizations 'under-utilize the value of one of their most coveted assets: the institutional knowledge of their employees, business partners and customers.' It made me think about our customers, the students. Is there a survey of our students? If yes where can it be found?
The Prediction markets work by soliciting input across a diverse group of "traders" inside and/or outside the organization. This sounds like shared governance.
The following are the steps for implementing such a system:
The first step in implementing a prediction marketplace is identifying the risk factors you want to monitor and the questions you want to ask about those risk factors.

The second step is deciding who will participate in your prediction market. Typically, you want as large and diverse a group as possible. Even departments traditionally not involved in decision-making processes may have a perspective that is useful to capture. If confidentiality of information is an issue, find a platform that lets you limit access to some questions and grant wider access to others.

Giving you time to address risk factors before they become serious issues is a key operational and competitive advantage. Prediction markets help cut through the clutter inherent in any large organization by revealing what people really think to ultimately create a more transparent environment where problems are known earlier and therefore addressed more effectively. Though managers may be uneasy about losing control over information they could once spin, most leaders agree: It is always better to know about a problem early on and put a plan in place while it's still containable. The alternative, as we have all learned, is crisis communications.
The article seems like a sale job. It is a commercial posing as an article but I looked at the Inkling Markets website and found some interesting ideas (I just may be really bored and think they are interesting).
For example I liked the following idea:
Idea Box / Idea Database / Idea Wall: A special email address, database, or physical space is set up to collect ideas by anyone in the company. Typically the ideas collected are reviewed on a periodic basis or are forwarded to an expert or manager in the area the idea pertains to. Metrics may be collected that measure the number of ideas created or the internal department or group with the most ideas and employees are measured on how often they've contributed.
But the idea I liked best was the following from their Build community page:
...what if you could make your users part of the content equation with a minimal amount of effort on your part? What if they could pose questions about the topic area they are already interested in and have others predict what's going to happen? Suddenly there is an entirely new channel of content available to your users that is completely self generating.

This new channel can be purely entertainment or can be designed for your customers or business partners to make them feel they are helping to drive product development.
I imagined a section on the Rio Hondo website where students, faculty, and classified staff can make suggestions. Then others can hit a buttons with Great idea or Terrible idea.
However I am back to reality now and can not wait till Tuesday when I go back to school to fight against terrible ideas and enjoy the good ones too.

B.I.G. Writing the B.P.A.


I attended the first B.I.G. (Banner Implementation Group) meeting on Monday. I replaced Jim N. on this committee. B.I.G. is the committee that will implement our new MIS system. The other faculty on the committee is Belen. There are two consultants, one works for Rio Hondo and the other works for Banner/Sungard (the software company). Our consultant seems like a no nonsense type of a man. He is in the process of figuring out Rio's business practices.
He asked each group to come up with business practices that we can implement. The software is very flexible and robust. However, it has to be customized to fit our business practices. Once the system is programed, it will be hard to go back and make changes. We have to decide on our procedures before we start implementing the system. The software is flexible but having contradicting procedures can lead to failure of the MIS. We need a road map before uploading any features because it will be messy to change anything midway through the process.

So here is my homework: I have to sit down and write down how teachers submit grades, Add/drop, and get our roster now. I need to get the Curriculum people to walk me through the curriculum process, so it can be duplicated in the software. I may have to consult with the SLO people too (I hope not. They are so slooo) if the software can track these tedious forms. I will have to consult with A&R and the Academic Senate to come up with acceptable procedures.

This is going to be a big change and people do not seem to realize how big! It will end all back door channels and the software will enforce the procedures. Before we write anything down please contact me and relay your concerns. As I write these BPAs I will post them here and send them out to faculty before presenting them to the Committee. If you see anything you do not like please hit the reply button or post your comment on this blog.

Enrollment Surge Click Here

The following is from Inside Higher Ed:
Community college enrollment growth is increasingly coming from online students, leading many institutions to create extensive online student service operations. Many of those institutions are also considering a shift in their course management systems...
Are we looking for growth in our Enrollment? To read the complete article click on the title of the post.

Community College Graduation Rates

Here is an article from Inside higher ed. The article reports on a research conducted by Community College Research Center of Teachers College, Columbia University.
"The study examines the validity of the “Student Right to Know” graduation rates, which all colleges must report under federal law. These rates measure graduation within 150 percent of the standard time for a degree — six years for a four-year institution and three years for a community college offering associate degrees. The study focused on Florida’s 28 community colleges"
The interesting part of this study is that these numbers ignore the transfer mission of community colleges. I remember transferring out of community college to the U.C. system without receiving my Associate Science degree. This was back in the 1980s but if I remember correctly I did not pursue the Associate degree because it meant another semester at community college.
Could we make our transfer rates match our associate degree? This could be done by setting our degree requirement equal to a full 60 units transferable General Education courses. We could call it General Education Associate of Arts or Science! If such an idea is forwarded, which programs would lose out?

The Typical Freshman


This is a link to Higher Education Research Institute. They survey students and have just released their survey on American Freshman for 2006.
One of the findings that deserve attention was that cost of college diverts students from their first choice. This should translate to higher enrollment numbers at community colleges.
Are we letting these students know of the possibility of completing their GE requirements at a fraction of the cost?
