National need for an understanding of science, technology, engineering, and math (STEM) Cannot be addressed only by educating future scientistsThe problem is deeper, more systemic, and solutions must extend to improved education for non-science majors. Non-scientists are called on to make decisions based on science

Discussion in the early spring of 07UG Dean Donna Hamilton, Jim Gates, and JGDonna was concerned that many of our best students on campus never took science
Many would “AP” out of science when they came inMany would be in majors like Business where more science wouldn’t be required
Donna organized a group (~15) of interested people who meet in the spring of 07

How does science attack problems to which the answer is not known
Most (virtually all) science courses we teach are about subjects that the answers are knownControversy is only presented historically and often parenthetically Conclusions are offered as if any reasonable person would have figure it out themselves
Even subjects like relativity

2. Scientists and engineers should be the ones to decide what types of energy we will use in the future (for example, nuclear, hydro, solar, or coal burning) because scientists and engineers are the people who know the facts best. What is your position, basically? Scientists and engineers should decide:
• because they have the training and facts which give them a better understanding of the issue.
• because they have the knowledge and can make better decisions than government bureaucrats or private companies, both of whom have vested interests.
• because they have the training and facts which give them a better understanding; BUT the public should be involved -- either informed or consulted.
• The decision should be made equally; viewpoints of scientists and engineers, other specialists, and the informed public should all be considered in decisions which affect our society.
• The government should decide because the issue is basically a political one; BUT scientists and engineers should give advice.
• The public should decide because the decision affects everyone; BUT scientists and engineers should give advice.
• The public should decide because the public serves as a check on the scientists and engineers. Scientists and engineers have idealistic and narrow views on the issue and thus pay little attention to consequences.

Example discussion section activity
Carbon Reduction TreatyYour challenge is to negotiate a treaty to reduce global carbon emissions by 50% by the year 2030. To simplify, we divide the
world (and your class) into two groups, developed countries (represented by the US) and developing countries (represented
by China). You should consider each other’s needs and consequences to quality of life as you negotiate (remember that negotiation is the art of compromise). Listed below are various
facts about each country to help you in formulating your arguments. Of the 50% reduction, how much should come from
the US and how much from China?Do the Chinese have the “right” to use as much energy per person as we do in the
US?

Energy Usage by Daytime Running Lights
How many cars are there in the US? – 200 Million
How far does the average car go per year?
1. 8,000 miles2. 12,000 miles3. 16,000 miles4. 20,000 miles
![Page 35: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/35.jpg)
Energy Usage by Daytime Running Lights
How many cars are there in the US? – 200 Million
How far does a car go per year? – 12,000 miles
Vehicles in the US drove 2.5 trillion miles 2.5 x 1012 mi
To figure out how many hours car lights are on time= distance/<speed>
How fast does a car go on the average? (highway and city stop and go)
1. 20 MPH
2. 30 MPH
3. 40 MPH
4. 50 MPH
5. 60 MPH
![Page 36: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/36.jpg)
Energy Usage by Daytime Running Lights
How long are they on for?Vehicles in the US drove 2.5 trillion miles 2.5 x 1012 miles(100 million families – 2 cars/fam. 12k miles/car)Assume average speed say 30 mph2.5 x 1012 miles/ 30 mph = 8 x 1010 (80 billion) hours of driving
At 50 Watts – 4 x 1012 Whrs - 4 x 109 kWh (4 Billion kWh), but they we must subtract the time the headlights would be on…
![Page 37: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/37.jpg)
Energy Usage by Daytime Running Lights
What fraction of the driving is at night when the headlights would be on anyway?1. 5%2. 15%3. 25%4. 35%5. 45%
![Page 38: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/38.jpg)
Energy Usage by Daytime Running Lights
Say you drive normally 25% of the time at night where the lights would be on anyway -> 0.75 x 4 x 109 kWh
So we use 3 x 109 kWh extra electrical power in our cars
A gallon of gas contains about 130 MJ/gal or 36 kWh/gal
The car engine is about 30% efficient so we get 10kWh/gal
3 x 109 kWh extra electrical power means 3 x 108 (300 million) gallons of gas/yr on DRLs
At $2.50 a gallon - $750M year and 5 Billion pounds of CO2
Realistically its probably less that as most DRLs use less power
![Page 39: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/39.jpg)
Are they worth it?
![Page 40: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/40.jpg)
Benefit of Daytime Running LightsStudies show anywhere from 7%-18% reduction
in daytime accidents from use of DRLs (mostly head-on left-turns)6,420,000 auto accidents in the United States in 2005. The financial cost of these crashes is more than $230 BillionIf there is a only a 5% reduction in crashes because of DRLs then you save ~$10 Billion per year 30,000 fatalities each year – 5% saves 1,500 lives (at $5M each -> $7.5B)

Students were asked:Why the trend?
“The economy has displaced global warming from the news”“It’s the scientists fault for not being definitive enough”
Why, since this is a scientific question, do the responses break down on party lines?
Dems want green industriesRepublicans want to protect big businessThey get their news from different sources

Final Exam (typical question)One gallon of gasoline today costs ~$2.50 &contains 1.3 x 108 J (130MJ) of energy –
Compute the cost of the equivalent amount of electrical energy (at $0.10/kWh from Pepco).
J=1 Watt Sec Hour=3600 sec so 1kWh = 3.6MJ
130MJ/3.6(MJ/kWh) = 36 kWh @ $0.10 = $3.60 Approximately how much would the gasoline cost @$2.50/gal to generate 130MJ of electrical energy using a gasoline-powered generator that uses an internal combustion engine (like a Honda generator). ~25% efficient so 4 gallons - so ~$10
![Page 50: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/50.jpg)
Hamburger meat has about 1,300kcal/pound and costs about $3/pound. How much would it cost to get the equivalent energy to 1 gallon of gasoline from hamburger meat?
1 kcal = 4184 joules 130MJ = 31,000 kcal /(1,300kcal/lbs) = 24 lbs
-> $72 There are about 8MJ in a pound of refined sugar and it costs $2 for a five-pound bag. How much would it cost to get the equivalent energy to 1 gallon of gasoline from refined sugar?
130/8 = 16 lbs so 3.2 - 5 lb bags ->$6.40

What are students expectations?
Students just want me to tell them “the answer”
What makes them think I know it?
Why should they believe it if I told them one?
![Page 62: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/62.jpg)
Student Comments (about the class) “The topics are current so it makes for a really interesting
class and it is really well-developed.” “This is a great class that everyone should be required to
take.” “…the course was awesome!!! I really dont like science at all
but I loved this class!!” “I absolutely loved this class! I'm so glad that it was offered
this year, and I would recommend it to almost anyone. The material covered was very interesting and very relevant. The class was kept engaging by clicker questions, occasional experiments or fun tasks, and discussions about interesting issues”
“Very interesting course but too many group assignments. ... I did however learn a lot and the course covers a lot of extremely relevant material to the world today. “
“this course was good shit”

An aside on clickers Facts (from my point of view) about clickers Clickers work to keep the class engaged Clickers work for attendance Clickers can tell you what your class is thinking Clickers can tell you when your class does or
doesn’t understand a concept Clickers can be royal pain in the ass for the
teacher!
Dealing with getting id #’s straightDealing with lost/forgotten clickersDealing with minor technical issues
Still I think they are worth the trouble

The Bonus Question idea
A bonus point is given if the majority of the class gets the correct answer
Students need to convince their classmates Only students who vote get the point, but it
doesn’t matter if you are right or wrong Lively discussions ensue

What makes Marquee courses different from most other courses at
the University?•The goals of the courses are independent of the subject matter – they are truly cross-disciplinary•The subject matter doesn’t drive the course•Community involvement in the process
•We meet over lunch for 2-hrs 3 times a semester•We have special sessions for “Marquee TAs”
![Page 66: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/66.jpg)
Community
![Page 67: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/67.jpg)
Community involvement in the process Senior faculty
People used to collaboration Strong institutional support: buy-in from the
colleges Community within the disciplines
We plan to keep course changing within the goals of the course (this week we talked about “Super Freaknomics” and geoengineering
This community provides innovative ideas and keeps the focus on the overall educational goals – rather than the subject material
Provides a focus for TAs

Pitfalls of course development Lot’s of smart people develop new
courses People spend considerable effort doing
research Course often start off great and slowly
deteriorate
![Page 69: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/69.jpg)
Courses and random walk If each new person changes a
course in their own way it takes you away from the starting point in a random walk pattern
If each person combines their changes with previous work in a systematic way – you can converge to better course
![Page 70: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/70.jpg)
The n+2 problem Mathematical induction says if I can show
something works for integers 0 or 1 and I can show it works for an arbitrary number n and that it also works for n+1 then it works for all integers n
In course development induction goes like this
I can develop a course and show it works for meI can pass it on (successfully to the next person teaching it)Therefore it should work for everyone
But it doesn’t always work for n+2 and beyond
![Page 71: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/71.jpg)
The n+2 problem Example
Physics 261/271 – engineering labStudents complained like crazy – they hated the labWe did a study and found several major problems
The pre-labs took forever because they were graded with more spread than the rest of the somewhat cookbook labs
Students spent way too much time on this prelab
We also found students were expected to take data, go home and figure it out and write it up
They had no help at home from the TAThey may have not recorded the correct thing or missed somethingThey didn’t really know how to analyze data
![Page 72: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/72.jpg)
The n+2 problem We changed the lab
We changed the grading of the prelabs to a 0, 10, 20 point system
We put computers in the labs and had them do all their analysis in class
We put in lab tests to see if they were actually learning the material and made them think about it…
We passed this course on to a colleague (who was very good).
He came to us with questions
“Why do this crazy prelab grading system?”
We had answers
When he went to pass the course on (n+2) the next person had questions too – he didn’t have many of those answersMuch of the research was lost
![Page 73: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/73.jpg)
Teaching as the opposite of scienceScience – builds on previous knowledge attained through study or practice.Most times when we teach we ignore all previous knowledge about the course from others
What did the students learnWhat did they have trouble withDid the course accomplish its aims
![Page 74: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/74.jpg)
Another example Physics 174 – a first lab course for Physics majors
(1996)
Course was created after a survey of faculty and students agreed on fundamental problems with our labsStudents didn’t know how to make basic measurements or hook up simple circuitsStudents didn’t understand error analysisIt was possible to miss the entire purpose of the course and get a “B”
The new lab was designed to solve these issues
Required mastery of certain skillsStudents couldn’t miss the key elements of the course and still get a good grade
![Page 75: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/75.jpg)
Physics 174
One lab was designed to show them that they could fit data to any function by minimizing chi-squared
They took data with the digital scope fed it into a spreadsheet – then fit it
Several years ago I taught the lab for a colleague
This lab had evolved so that the measurement was done differently and the objective which was the fitting was lost altogether.
Lesson – if you don’t make the educational objective clear, it may be lost…
![Page 76: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/76.jpg)
The software development model Courses need to be “owned” by a Department or a
group Material changes should encouraged, but be vetted
before they are permanently accepted The software development model
People write code and demonstrate it works
They provide test data to show it works
It’s checked into a library as the production version
Other people can check out private copies and modify/improve it as they see fit
Before it’s checked back in as the new production version it has to be vetted and tested by the group
This way things improve not just random walk!
![Page 77: Marquee Science & Technology Courses A successful example of cross-disciplinary course development](https://reader036.vdocuments.net/reader036/viewer/2022062501/568167e2550346895ddd463f/html5/thumbnails/77.jpg)
My mother and curriculum My mother in the school
cafeteriaWhy do you give them spinach if they all throw it out?
“They need it for a nutritious meal”
Many course have spinach for content
It doesn’t matter how good it is for the students they don’t get it
There is the counter argument that says “some actually do get it”.

My View
You could sink the Dover to Calais ferry half way across the English Channel and some people would make it to France, but would you schedule it this way?

What are our plans?• New course on the Chesapeake Bay• Develop a mentoring program for young
faculty so that so we train our successors, thereby building more sustainability into the program
• Raise funds for an endowed Marquee chair--that would rotate among the faculty
• Organize a Marquee poster day
