Revisiting Guiding Principles
So here are my guiding principles... PLUS
1. I will strive to use technology for making learning more accessible, engaging or creating deeper meaning not just because it is "there."
2. I will work hard to make sure my students are safe in the digital world and understand how to interact within it with respect for themselves and others.
3. I will remember that technology is the tool not the answer and endeavor to convey it to my students- because they are the answer!
4. I will learn more about technology from and for my students so I can help better guide their learning.
5. I will think about what 21st century skills my students can practice as they use technology and I will try to encourage them to develop these skills.
Best of luck to all!

Imperiled giant pandas need replanted bamboo forests in order to reconnect
Giant panda habitats are too fragmented and need to be reconnected in order for the endangered animals to maintain their genetic diversity, a new study shows.
The study, conducted by researchers from the Chinese Academy of Sciences and the China Wildlife Conservation Association, both in Beijing, was published July 23 in the open-access journal BMC Genetics .

Discussion Summary
This is a process, we are lucky enough to be lifelong learners.
Best practice is evolving too.
Trying a little bit at a time is OK.
Technology is one tool in the hands of what really matters in education- the teacher.
Finding the time to collaborate is important for teachers too.
Thanks, I'm sorry for the short post. If, you've been reading the news, you may have heard of a plane crash in Lake Michigan this week. (It's been in the national news because of a "goodbye" note found in the water after the crash.) The volunteer medical transport flight was carrying 2 pilots, a doctor, his patient and wife from Michigan to the Mayo clinic. The doctor was my uncle and one of the best men I know. The pilot was rescued but all others are still missing and presumed lost. We are waiting for word that the wreckage has been found and more. It's been a hard few days.
Digital Science Fair
The science fair really is the final unit of my class and take about 4 weeks of work to come to fruition. I'm planning to have my students make "In Plain English" scientific method videos early in the year and I want to link the best up with the wiki for review. Students will be able to use the Science Buddies site to choose a project and then during the research phase share additional helpful information on the wiki. I've asked them to share their topics with me on a wallwisher.com board. The final digital display I'm thinking I may leave up to students. I plan to introduce- with the help of my awesome teaching partners- some other applicable web 2.0 tools so they should have some basis for making a choice. I modeled Glogster with the "home" page of the wiki because I think that this will probably appeal to most of my 6th graders, being a "poster" type. I have a rubric that I use for the science fair that students help modify each year so the rubric is TBD. I'm deciding between having them share their projects on Edmodo or a specific blog set up for that purpose. That will probably depend on access issues at my school.
Here is my wiki: http://cubscientists.wikispaces.com/

Wallwisher
Also, in my poking around looking for ideas to modify my current science fair rubric so that it works for my digital science fair, I found this pretty comprehensive list of rubrics.
Oh, also you may have noticed that I've changed a few things about the blog. I'm trying to make it user friendly for my students and parents so that I can continue blogging here next year. Hopefully, it will help extend the walls of my classroom and perhaps make them feel more "semipermeable" for parents. :)

China's Wars Driven by Climate - Discovery News
Interesting discussion starter!
http://news.discovery.com/history/china-climate-wars.html
China's Wars Driven by Climate |
July 14, 2010 8:15:00 AM
Two millennia of foreign invasions and internal wars in China were driven more by cooling climate than by feudalism, class struggle or bad government, a bold study released Wednesday argued.
Food shortages severe enough to spark civil turmoil or force hordes of starving nomads to swoop down from the Mongolian steppes were consistently linked to long periods of colder weather, the study found.
In contrast, the Central Kingdom's periods of stability and prosperity occurred during sustained warm spells, the researchers said.
Theories that weather-related calamities such as drought, floods and locust plagues steered the unraveling or creation of Chinese dynasties are not new.
But until now, no one had systematically scanned the long sweep of China's tumultuous history to see exactly how climate and Chinese society might be intertwined.
Chinese and European scientists led by Zhibin Zhang of the Chinese Academy of Sciences in Beijing decided to compare two sets of data over 1,900 years.
Digging into historical archives, they looked at the frequency of war, price hikes of rice, locust plagues, droughts and floods. For conflict, they distinguished between internal strife and external wars.
At the same time, they reconstructed climate patterns over the period under review.
"The collapses of the agricultural dynasties of the Han (25-220), Tang (618-907), Northern Song (960-1125), Southern Song (1127-1279) and Ming (1368-1644) are closely associated with low temperature or the rapid decline in temperature," they conclude.
A shortage of food would have weakened these dynasties, and pushed nomads in the north -- even more vulnerable to dips in temperature -- to invade their southern, Chinese-speaking neighbors, the authors argued.
A drop of 2.0 degrees Celsius (3.6 degrees Fahrenheit) in average annual air temperature can shorten the growing season for steppe grasses, which are critical for livestock, by up to 40 days.
"When the climate worsens beyond what the available technology and economic system can compensate for, people are forced to move or starve," they said.
The study found more droughts and floods during cold periods, but the factors that contributed most directly to wars and dynastic breakup were soaring rice prices and locust infestations.
The Roman and Mayan empires, they noted, also fell during cold periods.
Zhang and colleagues speculated that periodic temperature shifts roughly every 160 or 320 years were related to natural climate changes, namely fluctuations in solar activity and in Earth's orbit and axial spin.
The team said the findings demonstrate that climate change can lead to unrest and warfare.
"Historians commonly attribute dynastic transitions or cycles to the quality of government and class struggles," according to the paper, published in the British journal Proceedings of the Royal Society B. "However, climatic fluctuation may be a significant factor interacting with social structures in affecting the rise and fall of cultures and dynasties."
But the historical evidence they found points to global cooling, not to global warming, as the culprit.
The scientists were cautious about making projections for the future. In 2007, the UN's Intergovernmental Panel on Climate Change (IPCC) said that man-made warming this century will lead to worse droughts, floods, harsh storms and sea level rise, with the potential to inflict hunger and misery on millions.

Wikispaces
I've also been fiddling with this blog and thinking about how to use blogs in the classroom. I really enjoyed looking at how other teachers are using them.
My exploration of Edmodo continues. I'm slowing getting the hang of how things work with it. I now have a dummy account and a real one for what it's worth. I'm sure it will be hugely confusing if I can't figure out how to delete the "play" one. Also note that they've launched an iphone app, yay! Love the connectivity.

Blogs and Wikis
Here are some I love:
GeekyMomma http://macmomma.blogspot.com/
Get your hankies out for her classroom blog and digital goodbye to her class http://weblogs.pbspaces.com/mrskolbert/2010/06/03/a-digital-goodbye/
and on the adoption and asian culture front:
Laugh out loud funny adoptive family fun http://salsainchina.blogspot.com/
Grace Lin (the chinese american children's author and illustrator... careful... it's easy to fall in love with her!) http://www.outergrace.blogspot.com/
OK and perhaps not too popular with this demographic but... I was raised by hippies and... feel strongly about this issue... it's about the right balance, people ;) She has some wicked good "unplugged" ideas.
http://unplugyourkids.com/
and of course I blog at http://www.lalaandpie.blogspot.com/
Wikis... they get more complex. My teaching partner has used them mostly to discuss classroom issues (behavioral primarily). I really like the idea of using them to develop a supplement to learning materials available in the classroom. They just seem a bit too complex for my middle school kiddos. I'll have to play around before I make a final judgement.

Generating an Argument
Reflecting on Online Data and Sims
This one could be extended to then ask students HOW or what causes eclipses... a common misconception is that an eclipse happens once a month.
Using online data can be tricky, as well, mainly because the math and reading skills of middle school students are often so divergent. Here is a resource that looks pretty great that helps middle school student use real data to solve problems... Problem based learning or inquiry :)

Participating in Citizen Science
Poking around this spring for more ideas... since I mostly teach earth science and ecology I stumbled upon scienceforcitizens.net. Science for Citizens connects students (or just plain you or I) to projects that involve collecting and submitting real scientific data to help solve real scientific problems. Some projects require analysis and some are pretty straightforward data collection. Here are a few that I'm thinking my 6th graders could participate in next year:
Snowtweets
The Quake Catcher Network
Those make sense for Montanan students and I'm also quite taken by What's Invasive! since we already to a project on our city park- a mile high mountain that we can walk to from school- Mt Helena City Park and some terrific folks at the Prickly Pear Land Trust graciously help educate our students on this wonderful resource.

Virtual Storytelling, Science in Plain English and Geocaching, Oh, My!
I posted a while ago about multimedia education and some research being done by Daniel T. Willingham. One of the ideas from his research that resonated with me was that just because a lesson has pictures or other media to supplement the words it does not always make the lesson more effective. Willingham goes on to talk about how the more you know and understand about a topic the more meaningful a more visually complex multimedia task or "lesson" will be for a learner. Working with middle school students, some of whom my class is the first real science class they have had, I've been really thinking about how my students are really "novice" science learners. This is where Commoncraft's "In Plain English" format really makes sense to me. It keeps it simple-stupid! Great for middle schoolers and other novices! ;)
So, I'm inspired to try the same type of thing with my students. I can check out a classroom set of Flip video cameras OR... applying what I learned in tech camp: I'd like to try using Photostory 3 to make a narrated slideshow in the "Plain English" style. Perhaps giving the kids a choice about which medium they'd like to create with. I played with Photostory 3 at tech camp. We made a video about germs in a middle school- I didn't bring my computer on vacation... borrowing my dad's (thanks dad!) or I would share. I'm going to try with my daughter to play more with some of the pics she's been taking on vacation. I'll post if and when that happens.
Also, we've been geocaching here and it is really fun! I may even make my 9 week elective class about geocaching! Watching my daughter teach her grandparents how to use their GPS today was priceless!
Check out what geocaching is if you don't already know.

Bots
Today is all about Bots. The students made "draw bots." I'm wondering how I can partner with our art teacher to design these in science and create with them in art. Here is a variation of what we made: http://blog.makezine.com/upload/2009/02/yet_another_drawbot/drawbot2.jpg
I'm thinking that we could collaborate on a "recycle, reuse, repurpose" project. The added science connections are electricity and, for middle and HS level students, the physics of how and why they "draw" the way they do. Students could experiment with the shape of the bot body, the length of the legs, the orientation of the propeller etc. Great critical thinking skill builder!

Day 2 @ Tech Camp
Now Edmodo.com, this I think might be the "Moodle" replacement I've been looking for. It looks a lot like face book and is simpler for kids (and teachers) to navigate than Moodle. It does lack some of the bells and whistles of Moodle but as I don't need to teach my class virtually... I think that I can live without them.
That's it so far... except that my daughter has started a blog to chronicle the adventures of her "hexbug." She's been taking pictures of it at Tech Camp this week.

I Heart Ted
My husband is an avid traveler and has planned to take each of our children on a special trip to mark their 10th birthdays. Our daughter is 10 today and has been requesting a trip to Costa Rica's Monteverde Cloudforest. Check out this Ted talk about rainforests. Oddly enough... Our daughter's been telling us for 2 years that she's going to college at Evergreen State (no idea where that came from, we're just along for the ride here).. and this researcher teaches at...
Evergreen. Sometimes you kick the universe and sometimes it kicks you. Happy Birthday, Lala!
Science and Literacy
1. "Students need to have a compelling reason
to read, write, listen, and speak, and meaningful
science content offers that reason."
I've always felt that way as a learner. I am not much of a writer. Reader, yes. Listener, yes. But speaking and writing has never been my thing. However, if what I am reading or listening to is compelling... that makes it easier. The "my summer vacation" essay was always HORRIBLE for me and not just because my summers were super boring. (Farm kids don't get to go on any vacations.)
2. "When you share performance expectations
with your students, you let them in on the
strategies that good learners use intuitively."
When I finally realized that "how" to learn things was not intuitive for kids that was huge. I have learned to be explicit about how to get there and where there is.
3. By writing as they read, students
also create their own study guides for review and
outlines for report writing.
Great point. I am going to have students do this for sure. I have struggled with how to make reading about science active in a meaningful way i.e. not just playing a reading strategy game.
4. "What did you find out?
How did you figure that out?
How did you get that idea?
How did you reach that conclusion?"
Love this! I'm going to make cards of these discussion questions and put them on lanyard to use with labs. Middle school kids need explicit prompts for discussions to work. Can't wait to see how it works out!
Finally, it is heartening to see that literacy standards relating to science and technical arts are being developed. I have always been concerned that both language arts and science teachers were missing this aspect of literacy. Students need technical reading, writing and communicating skills and many are not developing them. When my husband taught first year university students in general bio he used to get many a research paper that began, "The sleek, gorgeous animal flew through the warm tropical waters, flying like a mythical beast..." Gak! He likes to remind me that real scientists don't read (or write) romance.
Keynote and Alternatives to PP
Workshop #1...Well, this could have been more aptly called Intro to prezi.com. I've used this before and previously signed up for a free educators acct. Prezi is a web based presentation tool. It allows students (and teachers) to create presentations using zooming and panning. The kids in the class today seem to really love it. They can brainstorm or prewrite first and then make intuitive connections, adding multimedia and grouping. To me the visual experience of the final product is cleaner and more interesting compared to (most) information heavy, linear PP slides. My decidedly nonconforming non conformist daughter is loving it. It makes sense to her. I'd love to see what my students could come up with.

Technology Boot Camp
On another note, "Ask the Cognitive Scientist" is a column that appears in AFT's American Educator magazine. Here is a link to a very interesting article entitled "Have Technology and Multitasking Rewired How Students Learn? You can imagine why this caught my eye! While not exactly "guidelines" the author's four summary points are worth thinking about.
1. Encourage your students to avoid multitasking when doing an important task. Younger people are not better at multitasking. They are less bad because their brains have greater working memory capacity.
2. If a new piece of technology is placed in your classroom with the expectation that you will use it, take advantage of online teacher communities. Just like we're being encouraged to do!
3. Think about what the technology can and can't do. There are advantages and disadvantages to using technology... think about what you want to accomplish and whether the technology will get you there most effectively or not.
4. There is nothing wrong with engagement. Even though brain reseach does not show a correlation between having technology in the classroom and deeper understanding of content, if it just gets kids attention- that's OK too.
The video below is about Multitasking... cool stuff. My husband has been trying to tell me this for years, however, my response is "It is impossible not to multitask when you're outnumbered." :)

Guiding Principles
http://www.informationisbeautiful.net/visualizations/because-every-country-is-the-best-at-something/
Well, I'm still struggling a bit with the volume of new things and the sense of urgency that I feel emanating from the readings etc. Not sure what I really feel about that yet. I'm still questioning... Really? Technology is going to solve all of our perceived "problems?" Is it really an answer or is it more of a tool? I strongly believe that it cannot and should not replace a teacher or hands on experimenting but I am excited about how it can provide more learning opportunities to students-especially mine- who are geographically quite isolated.
I have a strong streak of Thoreau in me and I really just need to get outside and THINK a bit more on it. However, it has been raining for DAYS here on the dry side of the continental divide. I can't even take my kiddos out for a walk. We are all feeling stir crazy! But here's where I am right now in my process:
1. I will strive to use technology for making learning more accessible, engaging or creating deeper meaning not just because it is "there."
2. I will work hard to make sure my students are safe in the digital world and understand how to interact within it with respect for themselves and others.
3. I will remember that technology is the tool not the answer and endeavor to convey it to my students- because they are the answer!
4. I will learn more about technology from and for my students so I can help better guide their learning.

21st Century Skills?
So here are my thoughts: The imagery of education as a factory producing a product alluded to at the beginning of the chapter is one which I dislike intensely. But the idea of 21st century skills not only for the workforce- (really that is not the sum of a person's meaningful life)- but for successful citizenship, I am intrigued by. The examples of 21st century skills: adaptability, complex communications/social skills, non-routine problem solving, self management/self development, systems thinking, all sound like skills that were used when family farms were the norm and people collaborated for success rather than competed against one another in their "cubes" to have the most. (The U.S. competing against the rest of the world instead of collaborating for a common good got me going a bit too.) Somewhere along the line we have "untaught" or removed the opportunity to learn these skills. I'm not sure how or where that happened. The upshot is... I'm not sure I'd accurately call them exclusively "21st Century Skills."
Thoughts on "adapting" or applying the 21st century skill set in the science classroom: I really get excited about these. Using authentic scientific experiences in the classroom, I agree is best practice. Giving students the opportunity to "act" like real scientists- dirt and uncertainties, arguments and all, encouraging thinking outside the box or circle or whatever- what students often miss is the importance of creativity and collaboration in the scientific world. I'm excited by how 21st century technology will come into play in helping students develop these skill sets.
