This result reminds me that everything is asymptotic:

pSLO performance is leveling off in the low 50's. As I noted last week, the answer is 51, 52, 53 - you pick. Three years ago I got a 56% on a wholly different instrument for measuring math learning outcomes. And this is in tune with the course pass rate historically:

The course pass rate for fall 2004 and spring 2005 are aggregated above in a diagram used in the November 2005 math meeting is seen to hover right around 51%. At the end of the day I would argue that if qualified faculty are honestly implementing courses based on student learning outcomes and grading using instruments aligned with that outline, then the pass rates should be well correlated and aligned with the course performance as measured by aggregated learning outcome measures.

In other words, in one dimension I am aggregating grades to get a pass rate which are measured by tests aligned with the outline, in the other dimension I am aggregating learning on an outcome by outcome basis to get at an aggregate learning measure. It is two ways around a square matrix, or more simply, two ways around a square block. I end up at the same point: 51%.

Which always leads me back to the statement I made in 2003 - qualified faculty implementing outlines based on student learning outcomes produce grades that can be trusted which align with learning.

So what is the benefit of the item analysis? Maybe not at the institutional level where the same 51% to 56% is generated, but at the course level: in the detail table further below I can see what the student's are provably learning and what they are not learning, what I have covered and what I have not covered on the outline. Measuring learning has value, principally to me the individual instructor.

The summer's experiment will come to a close this week with the final examination and a last item analysis. I do not think I would want to attempt item analyzing every test in every course I teach every term. I return to the concept of item analyzing a representative sample of the final exams to produce a meaningful look at learning in math and science courses. In lieu of a more implementable system and course-wide for science and math, I will be looking to gather such data in December for program reports on the HCOP and marine science program. I remain open to suggestions and alternatives, but to date none of the faculty in HCOP nor marine science have proposed an alternate manner to measure learning for their program learning outcomes.

I would also suggest this approach would work to measure the math and science learning program learning outcomes in the general education core. I know a Scantron would help some of my faculty, I can only hope that would be in place by December when it comes time to gather this data.

That this approach, if taken, would not yield data until December, leaves the fall program evaluation report with scant little to add from last year other than updated data from the IRPO office.

I am always reminded of the Hitchhiker's Guide to the Galaxy when I see numbers up around 50%. In the book the answer to the meaning of life is 42, and that morphed into a social idiom that the answer to any problem for which the answer is not known is 42.

In 1992 Dr.Perry noted that half of the students will fail college algebra no matter what effort one makes. In the early 2000's my program learning outcomes assessment tool yielded aggregate outcome assessment rates of around 53% to 56%. Here in 2006 my aggregate program student learning outcome is headed towards a similar number as the summer term heads to a close: 51%.

Any measurement of actual math learning at the college level appears to be stuck at around 50%.

Feel free to delete this. I only report this as I feel as this is providing useful information for me directly, while also reporting on learning to those higher in the assessment food chain than I. I think this is a way forward for the math and science division.

Once I return to Palikir I will be suggesting to those in the math science division that they item analyze a representative sample of their final examinations, map the questions back to the outline, and use the item analysis to report on learning accomplished against the outline outcomes, much as I have done below.

While an item analysis of the final is certainly not the only way to assess a course and I am open to faculty developing their own assessment strategy in the division, ultimately I need a way to report on learning as specified in the outlines. If an individual faculty member in the national division does not have an alternate strategy that accomplishes this, then I would be requiring an item analysis of a representative sample of final examinations each term.
