Bob Calfee- A Mentor

Robert Calfee 1933-2014

Bob died last night. Bob was my mentor, the kind that sticks in your head long after you moved out of state. I remember the first time Bob spoke inside my head. It was 1999 my first AERA in New Orleans. I went to a session about early reading acquisition. Mid presentation by one of the leading researchers in the field I heard Bob's voice and unique cadence "It's articulation stupid".

Bob has taught me to think about variance, his metaphor of variance as a sausage still lives whenever I teach a methods class. Probably more than anything else Bob showed me how you can manage multiple projects and ideas by switching mindset. I remember watching Bob make the switch. Our meeting time was 30 minutes and when the time was up Bob simply moved to the next thing. We were still there in his office finishing the last details but he has already moved on.

I never accounted really for just how much I've learned from Bob, his analytic approach, his passion, his ever present mentorship.
A colleague just wrote me a note saying we should have our mentors forever. My first thought was, we will.

Finally I remember Bob giving me and Sarah money for dinner at the Mission Inn on our anniversary in those day of graduate school poverty. I would say rest in peace, but that too was not Bob's way.
He voice will always be with me.

Thinking Fast and Slow in Education- Part 1

I am currently reading Thinking Fast and Slow by Nobel prize winner Kahneman (see a book review here). I am still processing some of the information (or thinking slowly...) but I see some obvious implications for teaching and technology. The first is the positive bias- we almost always underestimate the challenge and overestimate our capacity, the second is our lack of ability to intuitively understand statistical properties of the world around us.
In  1999 I saw this first hand in a classroom. In a summer school based on Bob Calfee's WordWork we had one kindergarten teacher who claimed to have gone through the eight-week program in three weeks. We were surprised but she claimed that all of her students have a solid grasp of all short vowel CVC words and are ready to advance beyond it. How do you know? we inquired, she replied that she has been observing her students being successful in making words. Since we assessed students in every classroom on a biweekly rotation we soon had some results from the classroom. Only four out of 18 students could actually produce the patterns reliably without repeated teacher cues. In essence the teacher saw her best students succeed and conjectured that all of her students could.
This is the reason that we should have an emphasis on formal assessment points in which we can get an honest estimate of what our students can do- not what we believe or want them to. Often I hear teachers saying - I know this student can do a lot better - yet they didn't. Now, sometimes it is true and due to some setting event, then a retest is in order. But if a student is consistently under-performing in a well designed assessment opportunity- then we have simply overestimated their capacity based on effort, our support for their work etc.

In technology and especially project based learning that is emerging as a major component in the (welcome) push for 21st century skills we need to make sure that we have a solid way to assess achievement that circumvents our biases and gains a real windows to what students can do.
