The First Weeks of Class - February 2014

I’m through the first weeks of Coursera classes that started in January (posted about last month before they started).  I thought that 4 courses might be a little overwhelming…..and that has turned out to be true. All of them are well done and the topics are well-honed to my interests; dropping one is not an option. So - I have a flurry of activity to keep up. I’ve dedicated one day a week to each course and then use the other three days to read extra resources and follow threads outside the course entirely.

The Roman Architecture course is furthest along. I find myself looking at buildings differently; there are still a lot of elements of Roman Architecture is buildings constructed long after the end of the Roman Empire. The Jefferson Memorial in Washington DC is one example (the picture below is one I took of the monument a few years ago during the spring cherry blossoming). One of the threads I followed outside the immediate course material this past week was finding out how the impluviums actual worked; it wasn’t just catching/holding water….it was often an pervious basin that allowed water to filter down into a cistern which was then used by the residence as a source of cool water!

The three other courses (How to Change the World, Moralities of Everyday Life, and An Introduction to the US Food System) are all thought provoking. There are times they seem to converge rom their varying perspectives on the same topic: how can individuals live in a way that is good for them and good for the rest of planet (people and everything else on Earth). They are all very focused on the present and the possible futures we are creating - sometimes with intention and sometimes not.

The whole motivation for taking classes is very different for me now than it was back in my 20s. Then I was focused on getting a degree that would lead into a career. Now I am takings classes primarily because I enjoy being a student! I am taking courses about things I was always interested in but didn’t need for my degrees. Since I am not interested in a grade or certificate, generally avoid tests and time consuming projects....focus instead on going off on tangents that spin out from the course materials. What a difference the Internet has made in how students can find answers to questions!

Gleanings of the Week Ending February 1, 2014

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Bomb-Sniffing Rats - An organization in Tanzania trains African giant pouched rats to detect landmines and tuberculosis.  I was more interested in the TB aspect to this story rather than the bomb portion. Once trained, a rat can screen 100 samples of sputum for TB in 20 minutes!

The World as an Apple - A video using an apple to demonstrate how much arable land there is on earth from the American Farmland Trust

Interesting and Overlooked National Parks in America - Some of these have gone on my ‘future vacation’ list.

Fantastic Kaleidosopic Light Paintings Created in Camera - Long exposures and moving lights to create images.

How Parents and The Internet Transformed Clubfoot Treatment - Hurray for the non-surgical solution!

Global Footprint Calculator - If everyone lived the lifestyle of the average American, we would need 5 planets. I did the calculator for the way I live and the answer was 3.9 planets (so I am better than the average American but still pretty far from sustainable).

Setting the Context: A Brief History of EdTech - Infographic (click on the graphic to enlarge or get the graphic in PDF form here and enlarge within the reader) about how technology has evolved in society, business and education from the 1980s to today.

Intimate Portraits of Bees - From National Geographic.

Nature Soundmap - Recordings of natural sounds from around the globe. I listened to several and will come back to listen to more. They have that quality of being gently invigorating and relaxing at the same time.

Two recent posts from Richard Watson: Could the BRIC (N11 and MINT) wall fall? and Issue 34: Society and Culture (and other topics…listed on the right) 

Ten Days of Little Celebrations - January 2014

Over a year ago I posted about finding something to celebrate each day. It’s an easy thing for me to do and the habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations;’ here are my top 10 for January 2014. I’ve grouped them into 4 categories this month: food, my past, looking outdoors and learning something new.

Food

Scones. I’m not sure why I thought scones were too difficult for my cooking skills….but I avoided trying to make them for long time until I saw a recipe that used a food processor for the hardest part! Now I make them a couple of times a month and vary the recipe. The original was pumpkin and ginger. The scones I celebrated this month were raisin and ginger (I like the slivers of crystallized ginger so they are part of the ‘basics’ for all my scones!

Baked Apples. I’ve always liked baked apples but I tend to forget about them. This January we had apples that needed to be used up quickly….so I got back in the habit. I had baked apples three days in a row! I bake the in the microwave for 2 minutes then add other ingredients before microwaving for another 2 minutes. My favorite ‘other ingredients’ are orange zest, pecans, and marmalade!

Homemade soups. Soup is my favorite food on cold days - and I never buy soups in cans these days. Many times I enjoy the leftovers used in soups more than the original meal they came from!

My Past

Wedding Anniversary. I celebrated over 40 years of marriage this month. Noting the date always reminds me of the broader need to celebrate and appreciate the durability of our family ties overall.

Friend from Long Ago. Rediscovering a friend from a long time ago is such a pleasure. It is invigorating to rediscover that the kernel of our younger selves is still within us!

Look Outdoors

This January has been too cold here in Maryland to do much outdoors….but the views through windows have been intriguing.

Snow. The snow has stayed on the ground for a long time. At first it is pristine and there are bits on the larger branches of the trees. Then the tracks of deer and squirrels are evident the snow on the trees either melts or is blown away.

Fog in the forest. One morning the humidity and temperature combined to create a dense fog. The forest behind out house looked as if it were holding the fog in its branches.

Robins. The flock of robins from a few days ago was a pleasant surprise.

Learning Something New

The new semester on Coursera. I’ll write a longer post early next month …when I’ll have more experience with the courses. What I am celebrating right now is that the first week of the courses I’ve started has been so good!

Soil science. I went to a lecture on this topic and was surprised at how much I learned…..and that I followed up to check the soil suitability for my neighborhood (It was quite a relief to know that the soil was suitable for houses with basements!).

Gleanings of the Week Ending January 25, 2014

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

All of these outbreaks could have been prevented with vaccines - The US has taken a backward step when it comes to outbreaks of diseases like measles and whooping cough. It’s very sad that the downturn has been so abrupt in the past 4-5 years….and that we know why; when will the toll of these diseases reach a tipping point toward increasing mandates for vaccination. All my vaccinations are up to date (and I may ask for a whooping cough booster at my next annual physical since some if my volunteer work is with children).

Wellcome Images - Digital images from the many historical sources made available under Creative Commons licensing by the Wellcome Library, London. All low resolution images are freely available for download for personal, academic teaching or study use. The image at the right is a Mark Catesby illustration of a magnolia blossom and pod.

Top 20 Metropolitan Areas in the U.S.A., 1790-2010 - A very busy chart…but worth look at for a bit. Expand it and take a look. Some cities peaked early (like Baltimore); some didn’t get started until much later (like Dallas and Houston). New York has stayed at the top since it surpassed Philadelphia in the early 1800s.

An earthquake threat is building up in the central U.S. - Lots more people living in the area than there were in the early 1800s (when the last big earthquake occurred there.

Designing Your School of Choice: mySchool - An essay by Adam Renfro about his vision for ‘school.’ There are so many options for future schools….the big challenge will be to choose those options wisely. The balance between needs of the student and society will become more nuanced. It is interesting to observe the uniformity implied by core curriculum, testing, and building structures with the explosion of easily available learning environments that are anything but uniform.

How a Versatile Gut Bacterium Helps Us Get Our Daily Dietary Fiber - Another bit of evidence that our bodies are complex ecosystems with many organisms interacting…..organisms that we need to be healthy!

What's the best place to see or visit in your area? - This is a post where the comments are the main content.  I know in my area I have favorites - and the ones I recommend depend on the interests of the person asking!

To MOOC or Not To MOOC - Infographic. I learned a new acronym: SPOCs is (Small Private Online Courses)

NASA Finds 2013 Sustained Long-Term Climate Warming Trend - The Earth’s temperature has risen about 1.4 degrees F since 1880. The average temperature in 2013 was 1.1 degrees F since the mid-20th century. There is a video showing the temperature changes over the past 6 decades.

Roasted Chickpeas - A recipe I’m going to try this week.

Timelines

One of the side benefits of taking courses is learning about ways to depict information…and tools to assist with that depiction…in ways that enhance both perception/thinking and communication. I couldn’t resist looking more closely at two timeline tools. One was Tiki-Toki which a student in The Modern and the Postmodern Coursera course (being offered again starting Jan. 27) had used to make a timeline of the topics in the course. The other was a simpler timeline tool from readwritethink - a site I learned about via the K-12 education courses I’ve been taking on Coursera.

I used the simpler tool to make a quick graphic of the major events of my life. It was thought provoking to decide what events were really important to me. The last ones I added were the deaths of my grandparents; I haven’t had many people that I was close to die except for those four and it occurred to me that I still think of them relatively frequently….that their influence on me persists and is somewhat dependent on when they died.

Timelines are good ways to succinctly display time related items. The timeline above is the simplest form! I’ve wanted to create timelines before but they took a lot of effort to produce. Now I am celebrating that there are actually two tools that are easily available! The tool I used for the timeline above has the capability to have dates and images - features I will use next time. I have visions of including a timeline when I return from my next vacation….in the first blog post of the series! What about summarizing a whole year of travels? Maybe I’ll use the Tiki-Toki tool to create a timeline for all my Coursera courses too.

3 Free eBooks - January 2014

It’s time again for the monthly post about eBooks that are freely available on the Internet. The three below are my favorites for January 2014.

Reed, Chester Albert. Wild Flowers East of the Rockies. New York: Doubleday, Page & Co.1910. Available from the Internet Archive here. This book had great illustrations. I found myself looking forward to spring when I can out to find skunk cabbage and trillium.

Bailey, John; Schneider, Carri; Vander Ark, Tom. Navigating the Digital Shift: Implementation Strategies for Blended and Online Learning. Digital Learning Now. 2013. Available in several formats here. This book is a series of papers about the adoption of Common Core State Standards and the shift to personal digital learning.

Moncrieff, Ascott Robert Hope; Palmer, Sutton. The Heart of Scotland. London: A & C Black. 1909. Available from the Internet Archive here. I like the golden colors of the paintings by Sutton Palmer. They are full of details too - enough to make the 1000 words that picture are touted to be worth.

Gleanings of the Week Ending January 18, 2014

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Over 4,000 Reasons to Love (and Protect) North America’s Native Bees - many agricultural plants are primarily pollinated by native bees (rather than the honey bees that were brought from Europe that are uniquely equipped with the tools and techniques required to do the job. )…and they are declining.

Web Soil Survey - The WSS interface allows you to find out about the soil for a specific area in the US (i.e. an address). It’s provided by the USDA Natural Resource Conservation Service. Reports can be generated about the suitability of the soil for specify uses. For example, I requested a map about the suitability for houses with basements for my neighborhood. Where my houses sits was coded ‘green’….but at one edge of the neighborhood it was ‘yellow’ because the soil changes and there was another small area that was ‘red.’ This would certainly be a resource to check if you were building a house or buying one in an unfamiliar area! The builder can take steps to overcome the soil suitability issues….and avoid wet basements! There is also a site that provides the detailed descriptions of soils here. Did you know that there are 26,000 soil types in the US?

Ray Archuleta Soil Health Lessons in a Minute - Short videos about aspects of soil health from the USDA NRCS. Watch the one about the benefits of no-till farming!

Spectacular Photos of a Powerful Volcano Erupting in Chile - Awesome power of the earth to reshape itself.

Long-Forgotten Photographs Reveal Challenger Disaster As It Happened - Most people old enough to remember January 1986….know where they were and how they found out about the Challenger. It’s one of those sad, defining moments for the psyche of the US.

The truth about technology’s greatest myth - The impact of technology in our lives is not straightforward at all…there are positives and negatives...complexities…unintended consequences. Technology cannot be evaluated without the context of the people and societies using it - which means that it isn’t ever simple or entirely rational.

Which scientific ideas do we need to get rid of? - Some answers from some prominent thinkers

Salman Khan’s TED Talk ignited the conversation about online education. Why he’s doubling down on the school of the future - How can education keep up with the pace of the rest of society and the cultural nuances around the globe? One pathfinder is the Khan Academy.

European word translator - Enter one or two lower-case English words and see translations overlaid on a map of Europe!

5,900 Natural Gas Leaks Discovered Under Washington, D.C.: A Dozen Locations Had Concentrations High Enough to Trigger Explosion - Aging infrastructure can be dangerous…and very wasteful.

Microscope Memories

Over 35 years ago when I was in college working on an undergraduate degree in biology, my husband and I bought a microscope. The one we chose was as good as or better than the ones I used in the labs at school:  objectives, spider silk guide lines, wooden carrying case.  It was ordered from a local company and took several weeks to arrive. The microscope was a major purchase for us (I remember thinking that it cost almost as much as a used VW Beetle!). There was reciprocity involved in the decision since he owned a telescope and we were spending money to tweak it (cold cameras, mount modifications, new guide scope, and electric socks come to mind) and it was loosely tied to his physics major. The plan we both had was to forge ahead to grad school in our chosen fields and our hobbies would align with our academic work. Our ideas about what would come after graduate school were still vague and seemed very far in the future.

A few years later as I began graduate school, I decided that computer science was so much fun (I had supported us through our undergraduate years with programming jobs) that I decided to do graduate work in that field instead. There was not enough time for a microscope hobby so the microscope was carefully stored away with the idea that when I did have time, it would be a hobby I would start again.

The microscope was only unpacked a few times in the intervening years. We bought a student microscope that attached to our computer for my daughter when she was in elementary school. The quality of the image was not very good and the software didn’t work with current versions of windows by the time I wanted to use it a couple of years ago when I started this blog. That device was jettisoned but I still wanted to restart the microscope hobby. Recently I decided to buy microscope imager for my original microscope. It replaces the eyepiece and attaches to my laptop via USB. I dug out my wooden box of slides and cover slips. The prepared slides dried out years ago and were thrown away; there are only three slides and covers left!

It is a rude awakening to realize that I have forgotten a lot in 30 years! I will need to read up on microscope maintenance (it’s been in its wooden box for a long time) and decide on what other supplies I need aside from a few more glass slides and covers - immersion oil and stains come to mind. Once I decide what I need - I’ll have to order it; online ordering and shipping has certainly improved since I originally worked with this microscope but it is not instantaneous. I’m excited to be fiddling with the microscope again!

There will be a series of mini-projects - things I want to view and then write a blog post about. Feathers and plant material and molds are high on my list. My goal is to have at least one microscope based post a month. Stay tuned for my experiences restarting an activity from my early 20s!

Gleanings of the Week Ending January 11, 2014

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Iodine - A new site that formats drug information to be more easily understood by consumers. There is information about how it all got started on the TED site here.

An Animated Atlas of the Historical Geography of the United States - Maps are a visual pathway to history. Thanks to the University of Richman for making these available online with a good interface.

CES 2014: Audi Shows Off a Compact Brain for Self-Driving Cars - Good to have a car manufacturer getting serious about self-driving cars.

Remarkable coastal change from the recent UK storms - Sometime erosion is so slow it is almost unnoticeable. These ‘before and after’ pictures show the potential of storms to cause changes very quickly.

The Bright Side of Prions - When prions are in the news, they are often associated with terrible diseases like Mad Cow Disease. This article is about recent discoveries where prions perform positive functions in cells.

10 Easy New Year’s Resolutions to Transform Your Health and Well Being - Some of these are so easy….they are good prompts to do something ‘outside the box’ to improve your 2014!

Timeline of the far future - An infographic from BBC Future. This timeline is for one hundred quintillion years!

The Future: What 32 Ed Leaders Are Excited About - And more about the near term future of education and the potential of technology to improve outcomes.

Gulf Coast Wetlands Rapidly Declining - It includes a map of the gulf coast that shows the huge wetland loss in Louisiana between 2004 and 2009. They are subsiding underwater.

Why we need to sleep in total darkness - I need to get an alarm clock with red rather than blue numbers…or do without a clock in the bedroom at all! And I have installed f.lux on my computer to change the color the screen emits at night (software available free from here).

Gleanings of the Week Ending January 4, 2014

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Quinoa, Apricot, and Oat Muffin Clusters - Yum! I made these yesterday. There were some substitutions since I ‘made do’ with ingredients I had around the house: spiced fruit preserve instead of apricot paste, sesame seeds for the nuts/seeds, tahini instead of almond butter. I also used muffin cups that I had had for years (found recently when I was re-arranging the cabinets!).

Heat maps reveal where you feel emotions in your body - Hmmm….so people that are happy are physically warmer!

Beyond the Core: What about Other Important Outcomes? - What topics do you think are missing from the common core for K-12 education? Use this article to jumpstart your thinking.

Stranger than Fiction (Plant Biology) - An intro to the January issue of The Scientist online magazine. Read the full articles too: Plant communication, plant DNA challenging preconceptions about the evolution of life, and gold in plants.

Attacking Fungal Infection, One of World's Major Killers - When we think of microbes that kill we generally think of bacteria or viruses, but fungal infections kill 1.3 million people per year. I remember the mycology class I took (a long time ago) in college because of the beauty visible through the microscope: it was a blue world (dye) with complex structures. Reading this story makes me wonder if there were too few people from my generation that chose to pursue medical mycology and if our medical system has tended to focus only on the non-fungal microbes. Here’s another fungi story published this past week about How Mushrooms are Changing the World’s Winds.

Meditative Moments Found Within Dramatic Landscapes - If I went for a walk, there would be some places close to my house that look like these images! I took a few pictures from my door and decided that the wind and temperature in the teens made it too cold to venture further.

Marvelous Snowflakes - A video about how they form…in keeping with the view from my window in Maryland today!

The Best Wildlife and Nature Photos from NWF Staff in 2013 - My favorite is the pitcher plants (toward the end) but the sandhill crane (the picture after the pitcher plants) just visible in tall grass is a close second. And here is a group of nature photos from National Geographic: Rainforest Bugs and Best Wishes for 2014!

Elder Pharmacology - Many clinical trials exclude patients over the age of 65 as well as patients taking multiple drugs. And one of the key findings by gerontologists is that the biology of a young body is quite different from that of a young body. Put these together…and doctors medicating patients over 65 are virtually ‘flying blind.’ The status quo is not acceptable.

The book we all wish we could have read as children - I’ve added Travel Light by Naomi Mitchison to my wish list (The NPR article that is referenced is here.)

Memories of my Paternal Grandfather

My paternal grandfather was the oldest of my grandparents and he was the first to die. It happened over 35 year ago. I was still in college - old enough to have clear memories. I find myself comparing him to myself:

• He was more gregarious than me;
• He made an effort to be fair to everyone and he passed along that emphasis to me;
• He took care of household things so that they lasted 'forever'; I still have his hedge trimmers with his repair and  marvel at the other things I have around the house that are 40+ years old because I care for tools in the same way;
• Both of us only had one child and we were in our 30s when that child was born.

I look on the Internet Archive for books published around the time he was born and realize how much the world changed over the course of his lifetime. When he was growing up, farming was done with horses…then tractors. The farm houses had no electricity or plumbing but that too changed. He moved to town in 1950s because of drought that reduced the profitability of farming. He picked up odd jobs to supplement his savings. He was a quick study and a savvy one at ‘networking’ although he would have never called it that.

He was ahead of his time in another important way too: he bought me wooden blocks in a little wagon when I was very young. At the time, most people probably gave dolls to their little girls. He did construction projects with boards and nails in the garage with all my sisters too. He gave us the opportunity to enjoy activities that were not typically done with little girls and, by that example, showed us that our horizons were not limited by gender. Each of my grandparents probably contributed to that foundation, but from a different perspective and at different times of my growing up. My paternal grandfather was the first - when he gave me wooden blocks rather than a doll.

Today would have been his 113th birthday...and I'm thinking of him today.

Signing up for New Classes in the New Year - 2014

Just like traditional universities, Coursera has classes starting this month. It is challenging to pick - and I have probably overindulged by enrolling in 4:

Roman Architecture from Yale University because I’ve never taken an architecture class - it’s a different perspective on history. Also - this will be my first course from Yale.

Moralities of Everyday Life from Yale University because the increased lack of civility within political discourse in the US seems linked to ideas about morality. That makes the topic much more reality rather than theoretically focused.

How to Change the World from Wesleyan University because I thoroughly enjoyed Michael Roth’s previous course on Coursera: The Modern and Postmodern.

An Introduction to the US Food System: Perspectives from Public Health from Johns Hopkins University because it seems like our food system has been changing very quickly although it is difficult to grasp the changes as a whole…and the impact on health. It is a complex topic.

In addition, I signed up for Nutrition, Health, and Lifestyle: Issues and Insights from Vanderbilt for the one new lecture: Food Allergies and Intolerances: Separating Fact from Fiction. I took the course last spring/summer and it honed my understanding of nutrition in a way that helped me take off the last 15 pounds (to down to the weight I was at 25!).

I’m sure they will all have some extra reading that will supplement the videos. I’m planning on allocating a day of each week to each of one….and then using the other days of the week to catch the overflow. The courses do have to fit into the rest of life. I generally do the multiple choice knowledge checks embedded in the videos but not the quizzes or other assignments. I’m not after a grade and I prefer to talk about topics from the course with people I interact with face to face rather than other students virtually.

There was an article recently about MOOCs not living up to their original goal of online education approaching the quality of traditional colleges to the large population all over the world without access to such institutions. That is probably the case but, through refinement by iteration, they could improve on that goal. I’d like to suggest that MOOCs have an even larger role in society in the realm of lifelong learning - in enhancing the quality of life particularly for those that are long past the traditional college age. I’d like to see the end of course surveys probe this aspect. It would be interesting to know not just how many people did everything the course required to get a certificate or credit but how many students completed a subset like:

• Watched all the videos
• Read the online (free) references
• Scan parts of the discussion form
• Read all the references

In my case, I generally do the first three --- and get what I want from the course. A certificate or credit is not something I need.

It would also be interesting to find out how many people would be willing to pay some amount for the lectures to defray the cost of producing them. What amounts would be tolerated? Or does a charging scheme get too complicated to administer?

The bottom line for me is - I enjoy the Coursera offerings. I applaud the universities and professors that are participating. It is a positive development in education and the experiment has already succeeded for those of us that see these courses as a potent addition to lifelong learning.
