Subscribe to Chalk Radio ➜ https://chalk-radio.simplecast.comUploaded 19-06-24Our guest for this episode, Professor Rebecca Saxe, is MIT’s Associate Dean of Science. Prof. Saxe is also the principal investigator for her own laboratory, the SaxeLab, where she deploys powerful technologies such as functional magnetic resonance imaging (fMRI) to study the relationship between human thought and brain activity. (She originally went into cognitive neuroscience because, as she puts it, there’s nothing cooler than the fact that “all the thoughts we ever have” arise out of the firing of neurons.) Prof. Saxe is also deeply committed to improving how research is conducted and published, both in her own field and in others to support a scientific method that will be more robust and will yield more reliably replicable results. One of the ways to achieve this more robust science, she explains, is to make a shift toward more openness, embracing transparency in every step of the scientific process and promoting generosity in the sharing of data.Relevant Resources:MIT OpenCourseWare (https://ocw.mit.edu)The OCW Educator Portal (https://ocw.mit.edu/educator)Prof. Saxe’s faculty page at Saxe Lab website (https://saxelab.mit.edu/lab_members/rebecca-saxe-2/)“How We Read Each Other’s Minds” (TED talk video) (https://www.ted.com/talks/rebecca_saxe_how_we_read_each_other_s_minds?language=en)Nelson memo on open access to Federally funded research (PDF) (https://www.whitehouse.gov/wp-content/uploads/2022/08/08-2022-OSTP-Public-access-Memo.pdf) 9.401 Tools for Robust Science on MIT OpenCourseWare (https://ocw.mit.edu/courses/9-401-tools-for-robust-science-fall-2022/)RES.9-005 fMRI Bootcamp on MIT OpenCourseWare (https://ocw.mit.edu/courses/res-9-005-fmri-bootcamp-fall-2017/)Music in this episode by Blue Dot Sessions (https://www.sessions.blue/) Connect with Us If you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

Eric Grimson is MIT’s chancellor for academic advancement and interim vice president for Open Learning; he’s also a longstanding professor of computer science and medical engineering. In this episode, Prof. Grimson shares his thoughts on in-person and online education. We learn that he rehearses each lecture one, two, or even three times before coming to the classroom, and that he often pauses in his speech when lecturing to avoid distracting his students with “um”s and “ah”s and similar disfluencies. But though some of the techniques he describes might seem to reflect a view of teaching as performance, Grimson firmly believes that education should be a dialogue rather than a monologue—that students should be engaged as partners in the exploration of the material, even in an introductory-level class. “Anybody with enough curiosity ought to be able to explore a field,” he says, “and we ought to be able to teach at a level that opens it up to them.” The same conviction underlies his commitment to sharing his expertise online, whether by publishing his course materials on MIT OpenCourseWare or through purpose-built MOOCs on MITx.

Big idea: Debug early, debug often. Write a little and test a little. Don’t write a complete program at once. It introduces too many errors.
