Congratulations to Stephen Edwards and Virginia Tech: An endowed chair for innovation in engineering education

I’ve never heard of an endowed chair for engineering education at a research-intensive university. Bravo to Virginia Tech for creating such a position (and his colleagues for recommending him), and congratulations to Stephen Edwards for receiving it! A well-deserved honor! At its June meeting, Virginia Tech’s Board of Visitors confirmed the appointment of Virginia Tech’s Stephen Edwards, associate professor of computer science, as the new recipient of the W.S. “Pete” White Chair for Innovation in Engineering Education, effective Aug. 10, 2012.

The W.S. “Pete” White Chair for Innovation in Engineering Education was established by American Electric Power to honor Pete White, a 1948 graduate of Virginia Tech, and to encourage new interest in the teaching of engineering and improve the learning process.Edwards’ colleagues in the computer science department submitted the recommendation on his behalf. Cal Ribbens, the department’s associate head for undergraduate studies, cited Edwards as “easily one of the most innovative and energetic faculty members I have known in my 25 years at Virginia Tech.”

Disappointing Support for new NRC Framework for Science Standards from P21

I received the below statement via email, and I found it somewhat disappointing. Wholehearted support for the NRC Science Standards even though they ignorecomputing? From companies like Intel and Cisco? I had not heard of P21previously, and wonder what if there’s any connection between this group and Computing in the Core. My guess is that there isn’t, but there probably should be.P21’s statement on new framework for voluntary Next Generation Science Standards Washington, D.C. – June 5, 2012 – The Partnership for 21st Century Skills, P21, the leading national organization advocating for 21st century readiness for every student believes the National Research Council’s new framework for science standards offers an exciting new vision for 21st century teaching and learning.

The Partnership for 21st Century Skills commends the National Research Council for its Leadership States and partners developing the Next Generation Science Standards. P21 recognizes that the fields of science and engineering represent not just leading sources for economic advancement, but serve as dynamic platforms for pursuing new knowledge that can lead to a love of learning and support the development of the 4Cs – creativity, collaboration, communication and critical thinking. This conceptual framework can begin to reshape what students need to know and be able to do in order to cultivate 21st century leaders in science and citizenship. P21 particularly recognizes the conceptual shifts in the NGSS as well as the inclusion of the science and engineering practices in this new approach to standards development. 

The conceptual shifts emphasize real world interconnections in science, interdisciplinary integration across core subjects, and conceptual coherence from kindergarten through 12th grade, each of which aligns with P21’s approach to 21st century teaching and learning. More importantly, they emphasize not just the acquisition, but the application of content. P21 is pleased to see the NRC and the Leadership States embrace these shifts as each one is critical to preparing students for life and careers in the 21st century. The eight science and engineering practices also directly align with elements of the P21 Framework. From asking questions and defining problems to using models, carrying out investigations, analyzing and interpreting data, designing solutions and using evidence, these practices form the essential elements of the critical thinking and problem solving components of the P21 Framework. In addition, P21 commends the NGSS for recognizing the importance of communicating information as a scientific practice. 

Collaboration and teamwork are essential for academic and career success; therefore, P21 is pleased to see that the requirement for collaboration and collaborative inquiry and investigation begin in kindergarten and extend throughout the standards.P21 looks forward to working with the NRC, the P21 Leadership States and partners to ensure the next steps in this process of creating science standards continue to value not only content knowledge but also necessary skills for growth and success in the 21st century workplace. About P21: P21 is a national organization that advocates for 21st century readiness for every student. As the United States continues to compete in a global economy that demands innovation, P21 and its members provide tools and resources to help the U.S. education system keep up by fusing the 3Rs and 4Cs (critical thinking and problem solving, communication, collaboration and creativity and innovation). While leading districts and schools are already doing this, P21 advocates for local, state and federal policies that support this approach for every school.

P21 Members: Adobe Systems, Inc., American Association of School Librarians, Apple Inc., Cable in the Classroom, Cengage Learning, Cisco Systems, Inc., The College Board’s Advanced Placement Program (AP), Crayola, Dell, Inc., EdLeader21, EF Education, Education Networks of America, Ford Motor Company Fund, GlobalScholar, Goddard Systems Inc., Hewlett Packard, Intel Corporation, Knovation, KnowledgeWorks Foundation, LEGO Group, Mosaica Education, National Academy Foundation, National Education Association, Pearson, Project Management Institute Educational Foundation, The Walt Disney Company, Wireless Generation, Verizon Foundation, and VIF International Education.

Stretching your mind: Arguing for multiple programming languages for designers

Nice piece from Eugene Wallingford on Venkat Subramaniam’s talk at JRubyConf 2012. Reminds me of Janet Murray’s argument for why designers should learn programming, and about the BLS data saying that we need more program designers. Subramaniam began his talk by extolling the overarching benefits of being able to program in many languages. Knowing multiple programming languages changes how we design software in any language. It changes how we think about solutions. Most important, it changes how we perceive the world. This is something that monolingual programmers often do not appreciate. When we know several languages well, we see problems — and solutions — differently.

Why learn a new language now, even if you don’t need to? So that you can learn a new language more quickly later, when you do need to. Subramaniam claimed that the amount of time required to learn a new language is inversely proportional to the number of languages a person has learned in last ten years. I’m not sure whether there is any empirical evidence to support this claim, but I agree with the sentiment. I’d offer one small refinement: The greatest benefits come from learning different kinds of language. A new language that doesn’t stretch your mind won’t stretch your mind.

Carl Wieman on Effective Teaching

This is a really nice piece on a lecture by Carl Wieman, whom I have mentioned previously. In one page, the summary hits most of the key ideas in How People Learn. “Memory is not talked about much in education, but it is critically important,” Wieman said, and the limited discussion that does occur focuses primarily on long-term memory while short-term working memory is ignored.

He compared the latter to a personal computer with limited RAM. “The more it is called upon to do, to remember, the harder it is to process. The average human brain [working memory] has a limit of five to six new items, it can’t handle anything more.”

A new item is anything that is not in the learner’s long-term memory, he continued. “Anything you can do to reduce unnecessary demands on working memory will improve learning.”Among them is elimination of unnecessary jargon. Wieman asked: “That new jargon term that is so convenient to you, is it really worth using up 20% of the mental processing capacity of the students for that class period?” Demands of working memory can also be reduced by shifting some learning tasks, particularly transfer of simple information from the classroom to pre-reading assignments and homework.

Good academic leadership as a model for good teaching

There’s a Facebook meme making the rounds:


I am no expert on management or leadership. A management expert may look at the above chart and shake her head sadly about the misconceptions of the commonsense view of management. Nonetheless, the chart sets up an interesting dichotomy that is worth exploring, in relation to academia and then to teaching.The abrupt firing of President Teresa Sullivan from the University of Virginia raises questions about academic leadership and its goals. The below quote from a Slatearticle on her ouster suggests that she fit under the “Leader” column above:

The first year of Sullivan’s tenure involved hiring her own staff, provost, and administrative vice president. In her second year she had her team and set about reforming and streamlining the budget system, a process that promised to save money and clarify how money flows from one part of the university to another. This was her top priority. It was also the Board of Visitor’s top priority—at least at the time she was hired. Sullivan was rare among university presidents in that she managed to get every segment of the diverse community and varied stakeholders to buy in to her vision and plan. Everyone bought in, that is, except for a handful of very, very rich people, some of whom happen to be political appointees to the Board of Visitors. (emphasis added) via Teresa Sullivan fired from UVA: What happens when universities are run by robber barons. – Slate Magazine.

I have known academic leaders like this. Jim Foley is famous at Georgia Tech for generating consensus on issues. My current school chair (ending his term this month) does a good job of engaging faculty in conversations and listening — he doesn’t always agree, but faculty opinions have swayed his choices. Eugene Wallingford has written a good bit about how to live on the right side of the chart. I am sure that all of us in academics have also met one or more academic bullies who land more often in the left column:
The self-righteous bully is a person who cannot accept that they could possibly be in the wrong. They are totally devoid of self-awareness and neither know nor care about the impact of their behaviour on other people. They are always right and others are always wrong. R. Namie and G. Namie (2009) described bullies as individuals who falsely believed they had more power than others did…They tend to have little empathy for the problems of the other person in the victim/bully relationship.The bosses vs. leaders chart at the top of this post is about leadership, but it’s also about teaching. The common view of the undergraduate teacher veers toward the “boss” and “bully” characterizations above. We are “authorities.” The education jobs in academia are often called “Lecturers” or “Professors.” We lecture or profess to students — we tell them, we don’t ask them. We “command” students to complete assignments. We strive to make our lectures “always right.”

The best teachers look more like the right side of the chart at the top. From what we know about learning and teaching, a good teacher does “build consensus.” We don’t want to just talk at students — we want students to believe us and buy into a new understanding. One of my favorite education papers is “Cognitive Apprenticeship” which explicitly talks about how an effective teacher “models/shows” a skill, and “develops” and “coaches” students. The biggest distinction between a “boss/bully” teacher and a “leader” teacher is listening to students. A good teacher “asks” them for students’ goals and interpretations. How People Learn emphasizes that we have to engage students’ prior understanding for effective learning. A good teacher sympathizes with the students’ perspectives, then responds not with a canned speech, but with a thoughtful response (perhaps in the form of an activity, not just a lecture) that develops student understanding.I saw Eric Roberts receive the IEEE Computer Society Taylor L. Booth Education Award last week. I told him that I was eager to try a teleprompter for the first time. Eric said that he wouldn’t. He said that he would respond to the moment, the audience, and the speeches of the previous recipients. He would use the adrenalin of the moment to compose his talk on the fly. (Eric’s a terrific speaker, so he can pull that off better than me.) He told me that it was the same as in class — he listens and responds to the students.

At the end of this week, I’m heading off to Oxford where I’ll teach in our study abroad program there. It will be Georgia Tech students and Georgia Tech faculty, but physically, in Oxford. I’ll be teaching two classes: Introduction to Media Computation in Python (for my first time in seven years!) and Computational Freakonomics. I’ve taught at Oxford Study Abroad twice before, and loved it. Sure, Oxford is fabulous, but what I most enjoyed my past times (and what I most look forward to this time) is the teaching experience. I have 22 students registered in Media Comp (typically 150-300/semester at Georgia Tech, depending on the size of the lecture halls available), and 10 students in Comp Freak. We will meet for 90 minutes a day (each class, so 3 hours a day for me), four days a week. It’s an immersive experience. We will have meals together. Last times, I had “office hours” at my kitchen table, and in impromptu meetings at a lab after dinner.In enormous lecture halls with literally hundreds of students, it’s not always easy to be a “leader.” It’s easier in those settings to be the “boss” (even the “bully”), professing what’s right and ordering students to do their work. In a setting like Oxford with smaller classes and more contact, I will have more opportunity to listento my students, and the opportunity to develop my skills as a leader/teacher.

How do we encourage retention of knowledge in computing?

The scenario described in the experiment below has been repeated many times in the education literature: Students are asked to read some material (or listen to a lecture), and are then asked to do something with that material (e.g., take a quiz, write down everything they can remember, do a mind-mapping exercise), and some time later, they take a test to measure retention. In the experiment described below, simple writing beat out creating a mental map. Interesting, but it’s an instance of a case that I wanted to raise.This pattern of information+activity+retention is common, and really does work. Doing something with the knowledge improves retention over time.

So how do we do this in computer science? What do we ask our students to do after lecture, or after reading, or after programming, to make it more likely that they retain what they learned? If our only answer is, “Write more programs,” then we missed the point. What if we just had our students write down what they learned? Even if it was facts about the program (e.g., “The test for the sentinel value is at the top of the loop when using a WHILE”), it would help to retain that knowledge later. What this particular instance points out is that the retention activity can be very simple and still be effective. Not doing anything to encourage retention is unlikely to be effective.

But two experiments, carried out by Dr Jeffrey Karpicke at Purdue University, Indiana, concluded that this was less effective than constant informal testing and reciting.Dr Karpicke asked around 100 college students to recall in writing, in no particular order, as much as they could from what they had just read from science material.Although most students expected to learn more from the mapping approach, the retrieval exercise actually worked much better to strengthen both short-term and long-term memory.The results support the idea that retrieval is not merely scouring for and spilling out the knowledge stored in one’s mind — the act of reconstructing knowledge itself is a powerful tool that enhances learning about science.

E-mails show UVa board wanted a big online push: McLuhan rolls over in grave

Released emails suggest that one of the reasons that the University of Virginia’s Board of Visitors ousted President Teresa Sullivan was that she was resistant to online education Various theories have been traded among UVa-watchers in the last 10 days about the source of conflict between Sullivan and the board, and the e-mail records suggest that online education may have been among them. In her statement on the day the board announced Sullivan’s departure, D ragas used language similar to some of the columns that were being shared among board members, saying “We also believe that higher education is on the brink of a transformation now that online delivery has been legitimized by some of the elite institutions.”

Sullivan is not quoted at length in the e-mail files that were released, but one from an alumnus/donor to King ton says that Sullivan provided a “pedestrian” answer to a question about how UVa was embracing the online education revolution. Sullivan is not responding to press inquiries at this time, but sources familiar with discussions she has had on distance education said that she viewed it as an important trend, but had expressed skepticism about the idea that it was a quick fix to solving financial problems, and that she viewed distance education as having the potential to cost a lot of money without delivering financial gains. Sources also said she viewed distance education as an issue on which faculty input was crucial.

via E-mails show U.Va. board wanted a big online push | Inside Higher Ed. I’m just back from the ACM Education Council meeting, where Mehran Sahami put together a stellar panel on the topic of on-line education (also covered in Lisa K’s blog):
  • Woodies Flowers (MIT) who supports on-line training but believes that real education likely requires some “presence.” I mentioned previously that he’s been critical of MIT’s edX initiative. He emphasized the need to have higher quality educational software, using Avatar as his exemplar.
  • Candice Hillel (Carnegie Mellon University) who heads OLI and had the best research support for the forms of online education that they’re developing. She started with a great quote from Herb Simon, “Improvement in post-secondary education will require converting teaching from a solo sport to a community-based research activity.” She emphasized the team approach they use to build their software.
  • John Mitchell (Stanford) who leads the online education effort there. He led the charge in implying enormous changes for higher education. ”Will community colleges survive? How? Will college teaching follow the path of journalism?”
  • Peter Vigor (head of research at Google) who co-taught the 100K student on-line AI course was honest and pragmatic. He started on this because he wanted to do more than a book. He felt that the students really felt a “personal connection” with him, but when pressed, agreed that we don’t actually have much evidence of that. He sees the biggest role of these online courses is for updating skills and re-training. He says that the technology just isn't good enough yet. For example, the current tools don’t really respond to feedback — they’re linear experiences with no remediation or mechanisms for providing missing background knowledge.
  • Dave Patterson (Berkeley) who taught a MOOC (Massive Open On-line Course) on programming Web services. He was honest about the limitations of MOOCs, but still convinced that this is the beginning of the end for existing higher education. He pointed out that he also had a 90% dropout rate. He was the first MOOC teacher I've heard admit to “unbounded, worldwide cheating.” They were going to use plagiarism detection software, just to see how much cheating was going on, but they didn't need to. Large numbers of answers were “bit identical.”
One of the most important points for me was when Eric Roberts of Stanford pushed back against the flood of support for MOOCs, pointing out the costs of on-line education in terms of their impact on small schools, on general (especially legislators’) perception of the role of higher-education, and on what we teach (e.g., the media might encourage us to teach what we can easily do in these on-line forms, as opposed to what we think is important). ”Does ‘free’ wipe-out other things with demonstrable value?” Dave Patterson responded saying, “It doesn't matter. It’s going to happen.”

I thought I heard McLuhan rolling over in his grave. ”Media choices don’t matter?!?” But as I thought about it some more, it was less obvious to me which side McLuhan would fall on. On the one hand, McLuhan (in Understanding Media) argued that we should be aware of the implications of our media, of how our media change us. That view of McLuhan suggests that he would side with Eric, in thinking through the costs of the media, and he would be furious that Dave was unwilling to consider those implications. On the other hand, McLuhan would agree with Dave that media do obsolete some things (even things we value) while enhancing other things, and these media effects do just “happen.” Are we as a society powerless to choose media, to avoid those with effects that we dislike?

I see what happened at UVa to be about this question exactly. It’s not obvious to me that the MOOC efforts are better than existing higher education, in terms of reach into society, in terms of effectiveness for learning, and in terms of constructing the society we want. They serve a need, but they don’t replace colleges (as of yet). Teresa Sullivan’s concerns expressed above are well-founded, and she was wise to be hesitant. On the other hand, as Dave Patterson said, “It’s going to happen.” The UVa President may have been run-over because she didn't hop on the train fast enough for her Board of Visitors. Can we consider and choose our media, based on the implications we want, or must we accept the new media as inevitable and get pushed out of the way if we don’t embrace those media — even though those media could possibly destroy the institutions we believe serve an important need?
