Student blogs replace worksheets

By Eric Brunsell

Posted on 2011-05-23

Blogs provide a great way to extend the classroom beyond your 45 minute class period.  They can be used in a variety of ways to spark discussion and student research.  Chris Ludwig, a high school science teacher in Colorado, wrote this blog post to show how he used blogs this year to fundamentally change the way he assigned homework.

One of the major changes that I made this year was to switch to using individual student blogs as the centerpiece of student assessment (the other major change was to implement standards-based grading). I started using student blogs for a number of reasons including:

  1. I was tired of grading worksheets with the same copied answers on them.
  2. I realized that these worksheets weren’t always helpful in learning content, and in fact, much of the time they got in the way of learning.
  3. Student in my classes have access to a MacBook cart whenever they are in my classroom and we have fantastically dependable wireless internet connectivity for these laptops (yay tech support!).
  4. Blogging platforms like Blogger and WordPress are free.
  5. I’m increasingly wary of multiple choice anything as real assessment and wanted students to write more.
  6. I wanted students to have a permanent, online record of their achievement throughout the year, not some pile of papers shoved in a binder (or trash can).
  7. I wanted students to have an audience for their work that would include each other, their families, the community, and the world.

Ludwig continues,

So how did we use the blogs? They became the go-to location to post assignments for me to read and grade. For a week or two, though, I operated a lot like I did last year, posting assignments on Edmodo and using its great assignment features to have students turn things in online, as well as posting them to their blogs. I realized that this was a duplication of effort and soon instead of sending out “assignments” in Edmodo, I just sent files and links as “notes.” This meant that these resources no longer came with a due date and that I was not using Edmodo to see who turned in which assignments.

Physical science resources

By Mary Bigelow

Posted on 2011-05-23

“I know what I mean but I can’t ‘splain it.” I used to hear that from my middle school students in physical science, especially on essay questions. Sometimes the concepts are indeed hard to ‘splain in words. Visuals and observations of real events can make the concepts more real for students.

Harvard Natural Sciences Lecture Demonstrations


For example, a recent NPR blog Cinderella’s Ball, This Time With Pendulums had a video of a set of 15 pendulums, each a different length. When released simultaneously, watch what happens as a camera placed on the side of the apparatus captures the motion. What’s happening here? Hmm. I wondered what it would look like from the front. And sure enough, there was a blog comment with the same question and a response with a link to a video of a slightly different setup but with the camera in a different position. I checked out the creator of the video, Harvard Natural Sciences Lecture DemonstrationsThe site has resources for teaching concepts in physics and mathematics, but I spent the most time looking at the videos. These are short and to the point—great discussion starters or bellringers too.
Concepts in chemistry can be hard to understand, too. Middle School Chemistry from the American Chemical Society can be helpful. This series of lesson plans uses the 5E framework for lessons on matter, changes of state, density, periodic table/bonding, the water molecule, and chemical changes. The lessons include hands-on activities, simulations and animations, and student handouts.

Spring bird sightings bring reflection on conference sessions

By Peggy Ashbrook

Children look at downed and abandoned nest before returning it to where it was found.

If children bring a downed and abandoned nest to school, have them return it to the same location.


http://en.wikipedia.org/wiki/File:Turdus-migratorius-002.jpgSpring migration brings additional bird species back to their nesting range and in numbers that children can easily observe. There have been plenty of American Robins pulling up worms from the rain-soaked ground. And the children discovered a Robin’s nest in the shrubby tree on the playground, not under our noses but just above them. Your class can become citizen scientists by sending information about the nests they find to NestWatch, a nest-monitoring project developed by the Cornell Lab of Ornithology in collaboration with the Smithsonian Migratory Bird Center, and funded by the National Science Foundation. Begin by having your students observe and draw the nest without disturbing it.
The interest in bird nest building grew when a child brought in a nest with eggs that had been downed by storm winds, and unattended by the parents for days. (Note that the US Fish and Wildlife Service administers the Migratory Bird Treaty Act and that states also regulate possession of nests.)    We looked at it closely but did not touch it. Children try to build a nest using potter's clay, leaves and sticks.
Then we tried building a nest using sticks, grass, and pottery clay. The almost three-year-olds loved getting into the clay, and found the nest building too difficult to work on for very long.
It’s amazing how many species of birds can be seen in one location. Lisa Gardiner wrote about looking for birds in San Francisco’s Golden Gate Park with a team from BirdSleuth who were leading an NSTA National Conference workshop called Exploring Birds and Citizen Science. Birds hadn’t caught her attention the first time she walked the route on her way to the workshop, “Yet once I was looking for birds they seemed to be everywhere.” National and area NSTA conferences are great places to get support for teaching science in early childhood, learn some fascinating science content to share with your students, and to get “how-to” tips for teaching. I always come home with new resources—materials, websites, and contacts—and renewed enthusiasm. Maybe one of my or your students will be inspired like Noah Strycker who wrote about his experience studying Adelaide penguins in the Antarctic in his book, “Among Penguins: A Bird Man in Antarctica.”   Strycker became interested in bird watching when an elementary school teacher pointed out chickadees and grosbeaks on a bird feeder outside the classroom window. Read his blog to keep up with his travels along the Pacific Crest Trail which he kicked off this week, on May 19, 2011. I wonder what birds he will see?

On being a "cooperating" teacher: The greatest lesson ever

By Mary Bigelow

Posted on 2011-05-19

In a previous blog on student teaching, Christina Atton reflected on her student teaching in science. Her cooperating teacher, Ms. Chevin Stone (from Donald E. Gavit MS/HS in Hammond, IN), shares her experiences as Christina’s cooperating teacher.

Chevin Stone


When my principal emailed asking for a volunteer to work with a student teacher in a science classroom, I jumped at the opportunity. Part of me thought it would be great to have a few weeks of not writing lesson plans while advising a new recruit to the fine profession of science education. At the cooperating teachers meeting, I found out I’d only have my student for seven weeks. What could she possibly learn in a seventh grade classroom in such a short time?
She learned about classroom management.
The thing one never learns sitting in a college classroom is how to manage a class. You can talk about the techniques, watch all the Harry Wong videos ever produced, and even watch a veteran teacher work his or her magic in the classroom, but until you have to get students settled, on task and learning, it’s all just talk.
She learned that lesson that hard way. My kids are accustomed to me, the stern, “get it done or die” teacher who can keep the majority of the class on task and still sip her cup of tea without breaking a sweat. The best, most well-planned lesson is for naught however, if you don’t have control of the classroom.
My student teacher found out one night that her supervisor would be coming in first thing in the morning. The class being observed was an honors class of bright kids, some with Attention Deficit Disorder. The plan was for me to stay to take pictures of the center activities she was doing. I’m glad I was there.

In every seventh grade class, it seems there is at least one young man who makes you wonder what makes him tick. In this honors class, I have six like that. Never mind a visitor in the room, never mind I sat between the two groups of three as they worked. Between taking pictures, I quietly kept my “gang of six” on task. They decided, however, “It’s a sunny day, the birds are chirping, the girls look nice, and who cares if there’s ‘company in the house’——let’s put on a show.” Before the class period was over, three notebooks disappeared, a quarter used in one of the centers was reported missing and reappeared mysteriously on my desk, and a student reported all of his personal belonging stolen. On a bright note, the closing discussion went very well. (As part of a lesson on DNA, we discussed whether DNA really proved Osama bin Laden was dead.)

Christina Atton, Student Teacher


I’ve never been so embarrassed in my life. My student teacher corralled the group several times; only to have the “gang of six” find new ways disrupt and cause disarray whenever I moved more than five feet away from them. I even went so far as to haul three of them out of the room and give them one of my patented lectures. I apologized to the supervisor (who, incidentally, had been a professor of mine) and when my student teacher returned from her conference, she was frustrated, irritated, and just downright angry.
Classroom management is not something that can be learned in seven weeks. It takes nearly 4 weeks for a veteran teacher to pin down the nuances of personality and behavior. She’d been dutiful in watching me use various techniques to get the lesson started, moving, and flowing smoothly. I often use centers, which can be a great teaching/learning tool. However, in a large class, it’s important to work the “center magic” in such a way that everyone is on task. Her center-based lesson worked for every class except this one.
I bet she reflected on that experience in her journal for at least two pages.
I’ve been teaching for seven years, and I admit that I have days when classroom management is a hard row to hoe. But then again, as I told my student teacher, this is a science classroom, where we learn by doing inquiry. There’s going to be some chaos, some noise, some disarray.
Well, she learned a lot about classroom management. But what lesson did I learn? I think I’ve learned that I have something to share. There aren’t that many teacher candidates interested in science, so those who choose this discipline are precious to us all as science educators. I’ve learned what is important to me, as an educator and passed that on to her. I’ve learned how to be a mentor.
I’m going to miss her. She’s taught me a thing or two and I had a box full of goodies for her (I love a new curriculum cycle when I have lots of things to give away!) It’s my greatest hope she takes her passion for the craft to places where it is most needed and that her students learn to appreciate and love science as much as both she and I do. This has been fun; I must do it again sometime!

Collaboration and learning

By Mary Bigelow

Posted on 2011-05-14

Did you see this article from Education Week shared on NSTA’s Facebook page? Study: Interactive Tools Matter More Than Teaching Methods
The article has more details, but basically in the 12th week of the semester, a college physics class was divided up. For the next week (3 hours of instruction), one section continued the lecture approach with the professor while the second was taught by two graduate students using an “interactive method including short, small-group discussions, in-class ‘clicker’ quizzes, demonstrations and question-answer sessions. The teachers got real-time graphic feedback on what the students were learning and what they weren’t getting. ” On a quiz covering that week’s content, the second group outperformed the first “The best scores in the traditional class were below average for the interactive class”  “In addition, student attendance and attention were higher in the interactive class. ”
Those of us in the K–12 world are probably not surprised by the results. Many of us already vary the instructional strategies in a class to get students actively involved and use formative assessments for feedback on student learning. But it’s a fascinating study, and one that could be validated with your own teacher action research.
From what I read, I do wonder if perhaps the novelty of the strategies (technology and collaboration vs. large-group lecture) and having two instructors contributed to the results. It would be interesting to follow up on these variables.
The EdWeek article begins by asking “Who’s better at teaching difficult physics to a class of more than 250 college students: the highly rated veteran professor using time-tested lecturing, or the inexperienced graduate students interacting with kids via devices that look like TV remotes?” I think this question poses a false dichotomy based on stereotypes—the stodgy veteran lecturer vs. the hip technology-using newbie. I would like to see a study on what happens when “highly rated veteran” teachers use collaborative strategies and technologies—for more than 3 hours of instruction!

In a workshop this week, teachers (which included veterans and newbies) used several Web 2.0 tools that could foster student engagement and collaboration. I observed that when the participants (teachers) used  the discussion forums on the course Moodle site, their contributions were more detailed and reflective than if we would have asked them to share out loud.
Another tool we used was lino a web-based communication  system that mimics posting sticky-notes on a bulletin board. The instructor creates a board and shares the URL with others who can post notes on it. The applications are endless—we asked the groups of participants to each post 4 notes: a definition, examples, nonexamples, and questions (color coded). Each team worked on a laptop, but they could what others were posting in real time. We then debriefed as a large group, with all of the notes visible on screen.  The “canvas” can be saved. I could also see using a canvas for an ongoing KWL chart for each class, a quick way to review, or an exit activity. Hmmm.
We also dabbled with Mindmeister, a tool for brainstorming and creating mindmaps (similar in concept to Inspiration). Once again, the instructor sets up the map and shares the URL. In real time, others can contribute. The map can be saved. It was interesting to see the collaboration in real time via laptops as participants added to or commented on and idea from someone on the other side of the room.
Both of these tools have a basic free version that requires login for the instructor. Others do not need a login to participate. I’m sure that students (and teachers) would catch on quickly!
Note: the study was recently published in Science.  A paid AAAS membership is necessary to see the entire article.

The gourmet science lab

By Claire Reinburg

Posted on 2011-05-12

Activities that focus on food and cooking can help students see how relevant and fascinating science can be in everyday life.  In a recent illustration of the enduring appeal of food’s scientific underpinnings, one of the most sought-after classroom slots for Harvard undergraduates is in the Harvard School of Engineering and Applied Sciences’ course “Science and Cooking.” Last fall in the class and accompanying public lectures, 13 well-known chefs dished on how they use food science in their celebrated restaurants, creating foams, spheroids, and other avant-garde features of their culinary offerings. Why not infuse your own lessons with a cooking activity to stir up students’ interest and appetite for science?  Author Sarah Young’s new book Gourmet Lab: The Scientific Principles Behind Your Favorite Foods is a collection of hands-on experiments that challenge grades 6–12 students to take on the roles of scientist and chef as they boil, bake, and toast their way to a better understanding of science concepts from chemistry, biology, and physics. Read the May 2011 issue of NSTA’s Book Beat for a free lesson from the book, “Cold Milk,” in which your students will measure the energy transfer in the creation of ice cream.  May’s Book Beat also offers grades 3–6 lessons on food-related topics  like chemical change in cooking pancakes and measuring the relative acidity of everyday foods like corn, lemons, and apples.

All you earlybirds out there are in for a treat this month if you look eastward just before dawn (and the weather is clear).  Four planets will be engaged in a slow-motion dance, aligning themselves differently day by day in a tight segment of the sky.
NASA has created a nice video describing the phenomenon:

All day in the science lab

By Mary Bigelow

Posted on 2011-05-11

For the past few years, I’ve had a self-contained fifth-grade class, and my students and I enjoyed doing many hands-on science activities and investigations. Next year, I’ll be teaching science to all of the sixth-graders. The science classroom is well equipped, but I’m looking for suggestions on managing five sections of science every day, especially labs.
—Elizabeth, Bowling Green, KY
In a self-contained classroom, you could be flexible with the schedule. If a science activity took a little longer than expected, you could adapt. But your new situation will be sensitive to the bell schedule. Your classes will be back-to-back, allowing little time between dismissing one class and welcoming the next. Preparation and organization will be important.
Plan your activity for the amount of time you have. If you have a single period (e.g., 45 minutes), you are limited to investigations that can be completed (including the introduction and cleanup) within that time or those that can be paused and continued at another time.
Prepare materials and equipment in advance. Have a surplus of materials so you won’t have to leave the room to get something. Assemble trays or boxes with materials for each lab group. A card in the box (or notes on the board) with an “inventory” helps students know what to return at the end.

If students get to class after the activity has started, allow them to work on the activity if and only if you first brief them on the safety issues (as you did with the rest of the class at the beginning of the activity). Prepare seatwork for those waiting for a turn or are not doing the activity. Students doing seatwork should remain at their desks.
Even the best class or most advanced students can run into difficulties. Resist the temptation to stay at your desk and grade papers or plan the next activity. Monitor your students as they work. In addition to looking for safety issues, you can do some formative assessment as you walk around. You can ask and answer questions, guide their thinking, and eavesdrop on their conversations. You can have a list of lab skills and check off students as they demonstrate them. Also note anything that you would change for the next class or the next time you do this activity.
Time flies during an activity, and if the bell rings while students are still working, they’ll want to rush on to their next class. Students must assume responsibility for cleaning up at the end of the period so that everything is in place for the next class. Set an alarm or timer to provide enough time to clean up the lab stations and debrief on the activity.
Have a sign at each lab station with a list of cleanup tasks. Check each group’s lab station and their box or tray to inventory the equipment and materials before they sit down. Do not dismiss the class until the cleanup is complete and all equipment and materials are accounted for.
Just as in a self-contained classroom, you’ll need organizational strategies, such as labeling or color-coding the paperwork for each section of students, designated routines to hand in assignments, and a place to store 100+ science notebooks.
Another challenge in teaching several sections of the same subject is maintaining your energy level. Even though you’re doing the same activity all day and hearing the same questions, it’s a new experience for each section of students. Your enthusiasm in the last period class has to be at the same level as first period.
And wear comfortable shoes on lab days—you won’t have a chance to sit down!

For the past few years, I’ve had a self-contained fifth-grade class, and my students and I enjoyed doing many hands-on science activities and investigations. Next year, I’ll be teaching science to all of the sixth-graders.

 

Rubrics and assessments

By Mary Bigelow

Posted on 2011-05-08

While reviewing some materials from a workshop, I came across a few online gems this week to add to the SciLinks keyword assessment. Even some of the experienced teachers in the workshop had to stop and think about the differences between analytic and holistic rubrics. We were guided to Jon Mueller’s page on Rubrics for a clear and concise discussion, with examples.
Creating analytic rubrics (which include both criteria and descriptions of the levels of performance for each) can be a time-consuming effort (but worth it). The Rubric Maker website looks like a good tool. The full version requires a subscription (for a fee). But there is a free version, the difference being that the finished rubric cannot be saved on the website or shared via the website. It can be downloaded as an Excel or HTML file that maintains the formatting, and the Excel version can be further revised/edited. Once you enter a grade span (Primary, Elementary, Middle, High) and a title, you’re able to choose criteria and descriptors. You can edit most of these to use your own terminology or performance levels.  A nice feature is that it also creates a student “checklist” with a description of each criteria (e.g., I proposed a hypothesis that can be tested by my experiment. I followed safety rules.) This would be really helpful to share with the students. There are other rubric generators on the web, such as Rubistar, which requires a free registration. You can create, save, and print a variety of customized rubrics right from the website.

When I got home from the workshop, I poked around the rest of Dr. Mueller’s site, the Authentic Assessment Toolbox. My reaction was WOW—this is a wonderful tutorial or guide through the process of creating assessments that are based on identified standards/objectives. He writes in a conversational style and includes lots of examples and a glossary of assessment terms. I really enjoyed reading the “Workshops” section which are basically think-alouds as he “converses” with a teacher and guides them through the process.
Exploring these resources could easily be a professional development project on assessment or the development of common rubrics.
