#clmooc #digilit Sunday A Walk in Public Places

LittleFreeLibrary
Created in Google Stories on Ipad;  I could not add the picture I took today down on another street
Couldn’t add:
Our side of town was once owned and maintained by the government during the building of Grand Coulee Dam, and our town benefits from that infrastructure and foresight. Parts are still maintained by the city. It’s a lovely neighborhood.
How different is this walk than yours? than my students? than your students? What is the same?
What are some benefits to the public areas in your neighborhood?
What issues are there?
What values are shown by the public areas?
How do people and governments care for these areas?
What norms would make these areas accessible and welcoming to everyone?
Would you be willing to accept norms and accept responsibility for helping care for public spaces?
Question to ponder…. what’s your walk? what’s your take?
What tool would you use to create a walk of your public spaces, and help begin a discussion that promotes and enhances those areas?

Teach Search Teach Research

Oh yes! My PLN friend, Denise Krebs, reflected on her students’ research skills in her blog post “A Need for Researchers Workshop,” just as my NSD colleagues did the same.

Even with our structured science project with Gooru Learning (goorulearning.org), our students needed help with search terms and relevance, “chewing” and “digesting,” a metaphor created by Denise:

Research Advice

We didn’t realize how hampered our students are in truly understanding and applying information. perhaps because of our focus on “What reading objective are you teaching / learning today?” Understanding requires more. We have frequent “Walk Throughs,” to gather information about our teaching as part of our WIIN participation. Part of the Walk Through includes posting our objectives, which the students should be able to explain.

As I reflect on the process, and look at the objective suggestions, I understand where I need to head. The results show that we are moving up in teaching “higher order thinking skills,” which is a good thing, and suggests where we plan to develop more teaching strategies. It seems by focusing on posting the “objectives,” our lessons may have been limited, and projects that require and enhance critical thinking skills slid to the background as we focused on our required Grade Level Expectation objectives.

Students in my class did focus on the suggested strategies of “Nonlinguistic Representations; Identifying Similarities and Differences; Cues, Questions, and Advance Organizers; Summarizing and Note Taking,” and drawing conclusions, making generalizations, and identifying cause and effect. We even developed an “ABC” format for answering questions, which I have written about here. On classroom-based evidence, students demonstrated the skills taught, skills that will help them with understanding ideas and concepts during a research project. However, on practice “standardized tests,” with only “standardized” teacher instruction, students fell back into their usual and general answers to questions, without re-reading or looking up the answers.

Because the students could choose their own topics, and because the science teacher and I were guiding the students with organizers, feedback, and conferences, we looked forward to student work that analyzed ideas and demonstrated understanding of their chosen concepts.

Of course, in independent projects, learning isn’t linear and tangents are allowed, but to stay focused on “the question” for research requires skills (especially “digestion” and “nourishment” as Denise has described.) Our students were learning about the world and were amazed at the concepts they had chosen. Their conversations among themselves were invigorating and questioning. The dialogue as such demonstrated an awakening of taste buds that caused them to wonder further. It was obvious they were building background knowledge each day, background in the concepts that interested each of them. But in sharing, most only “nibbled” and “spit” out facts without digesting the information and nourishing their understanding. To be fair, their work was interrupted by testing and other requirements, and we learned just how much students background knowledge in science needed kindling. Our project actually became a one of building background knowledge, and their sharing showed their new basic understanding; next year we can dig deeper.

My favorite summaries which shows the students’ understanding are these:

 Rocks:

 Two slides from, “How to Make a Speaker” (animated in presentation)

 

As you can see, the students did learn, and the information in Gooru Learning is geared for 5-8 and 8-12th grades.  Most students could explain their topic to us orally, and with time could have done more with explaining their understanding in writing. But the “more” we need, is through frequent time with reading, research, and reflection. The required objectives will be covered and taught, but the students will “do” the objectives in real research, not just to answer questions for meeting one objective.

Project/Problem Based Learning demands critical thinking skills, and requires the “lesser” skills in order to solve the project or problem. It’s the way I used to teach when I had a self-contained class. I started Pinterest Board on PBL earlier in the year and I follow the work at Edutopia. When asked to “post” objectives, the daily directives take over, and the projects slither away to make way for basic questions.

The science teacher and I now know that we need to combine our expertise and time for more project time in science and language arts. If we are to teach students to think critically and creatively we must spend more time on projects.

Our students need to: Connect, Contribute, Collaborate, Consider, Communicate, Create, Curate…

Connect: able to connect with relevant information and people

Contribute: able to add relevance

Collaborate: able to work and create together

Consider: able to analyze and synthesize ideas, organizing and transforming them into new understandings

Communicate: able to explain clearly

Create: able to share in new or remixed ways

Curate: able to document, organize, and annotate own and others’ work

Research requires careful consideration of ideas — to deeply understand  and — to “Read like a detective, write like an investigative reporter,” as suggested in the Common Core State Standards. To consider is a research must.

So, we also will  focus on higher order thinking objectives during research workshop next year with an emphasis on search, organization and collaboration, and making sense of the information:

Purposeful search: Using advanced search techniques to narrow the scope and raise the quality of information found on the web.

Effective organization and collaboration: Being able to organize all of this information into a comprehensive and growing library of personal knowledge.

Sharing and making sense of information: Sharing what we find and what we learn with the world, and using the knowledge of others to help us make more sense of it all.

We will entice the appetites of our students, present a feast from which they can choose their main dish, and guide them to digest the morsels of information to nourish their minds with new understandings from which they will present their own feasts for us to savor.

How do the organisms survive, and how do the scientists study them?

I the previous post, Jeff Bowman explains how in the petals of the Frost Flower, life can survive in the Arctic ( Science Article and Diigo Notes — sign in) and in the Antarctic (Science Article and Diigo Notes ).
But how do the bacteria live in what is now a much more salty habitat?

Let’s think about how these small, microscopic creatures live by first learning about diffusion and osmosis.

Osmosis
oz-moh-sis

“the process that causes a liquid (especially water) to pass through the wall of a living cell”

Diffusion
dih-fue-shun
“to spread out : to move freely throughout a large area” [from high concentration (lots) to less concentration (little)]

Video Explanation

These microscopic creatures must adapt their osmotic process to this new saltier environment, and Jeff and Shelley must create an environment that keeps this “osmotic” balance.

When Jeff and Shelley want to study these frost flowers and the creatures within them, they must allow them to melt in very salty water: “If you take these bacteria from their salty environment and place them in fresh water they will suddenly take in a lot of water and pop!…The bacteria might be living at a salinity of 150 ppt (parts per thousand), about five times the salinity of the ocean.  The melted ice might have a salinity of only 10 ppt.  So to keep the cells in sea ice from lysing (a fancy word for bursting) we have to melt the ice into water that is very, very salty.”

1. What is one part of the life of these microscopic organisms?
2. What do Jeff and Shelley need to do to study them after collecting them from the sea-ice?
3. Why is this important again?

 

 

Antarctica 3

How does something live in this very cold area?

Jeff Bowman explains how in the petals of the Frost Flower, life can survive in the Arctic ( Science Article and Diigo Notes — sign in) and in the Antarctic (Science Article and Diigo Notes ).

Open the notes, and see how the text connects to this summary:

Seawater turns to ice at -1.8° C
The ice has two parts: fresh ice crystals and salty liquid water
The ice crystals make the structure of the flower.
With more cold, more crystals form with less liquid.
Anything in the ice that isn’t water is forced out into the liquid.
The salt, the organisms, and anything else moves into the liquid.
The organisms must be able to live in this very salty liquid (called brine)– pockets of life in Frost Flowers on sea-ice.

1. Can you draw a series of pictures with labels to show this?
2. What is this important?  Take a look at Antarctic Wildlife to infer why.

Next post: How do the organisms survive, and how do the scientists study them?

We are fortunate to have the inside scoop on a Jeff Bowman’s research expedition to Antarctica.

What does Antarctica look like? What lives there? Look at these from National Geographic:

Video

Maps

Doesn’t this look like a desert ice fern?

Frost flowers? Take a look at these frost flowers from the Arctic and now look at the frost flower sample taken by the Jeff Bowman team in Antarctica here. In 2009, Jeff collected samples from the Arctic (image).

Is there life in these “petals?” What do you think?
