A wise professor once told us, “If the only tool you have is a hammer, pretty soon everything starts to look like a nail.” My takeaway from that class was that teachers need a variety of tools, from basic strategies to more specialized ones. And adding tools to the toolkit is part of professional development.
Recently, I’ve added Twitter to my toolkit. At first, I must admit, tweeting seemed like a pleasant diversion, but I’m experiencing its potential for professional development and communication. The other evening, I “attended” an event that began with a podcast of background information on a specific topic. Then the participants (several hundred from across the country) began conversations by tweeting questions/answers, observations, comments, and suggesting websites for further information. I had another person with me during the event, so we had the best of both—social media and face-to-face interactions. How did I learn about this podcasting/tweeting event? From Facebook (another item in my toolkit)—not bad for someone who started a career in science with a slide rule.
More on Twitter as a classroom, communication, or PD tool:

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:
- I was tired of grading worksheets with the same copied answers on them.
- 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.
- 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!).
- Blogging platforms like Blogger and WordPress are free.
- I’m increasingly wary of multiple choice anything as real assessment and wanted students to write more.
- 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).
- 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.

“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.

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.

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:
