Argumentation in Science

Science and Children cover Subtle differences in words can make a big difference: for example "arguing" and "argumentation." Our students see TV shows where arguing is the most common activity. People shout at and interrupt each other, spout ideas that may have little or no truth to them, and have little tolerance for different points of view or experiences. But structured and respectful argumentation can be a wonderful experience anywhere, especially in a classroom.

The skills involved in argumentation have to be taught and modeled, and the articles in this month's issues have many suggestions and real-life examples of what this kind of activity looks like and sounds like in a real classroom. (I can think of a few talk show hosts who should read these, too!)

Connecting Science and Literacy Through Talk describes the benefits of whole class discussion to debrief, summarize, and reflect on learning. What the authors describe is not a "discussion" that includes interrogation by the teacher in a Q/A format, but active listening and engagement by the students (with their science notebooks). I met a teacher once who boasted that her students were so busy that they didn't have time to think. But the authors of this article would argue that "Although direct experience is crucial to inquiry, students may learn little from the hands-on experiences if they are not given adequate time to make meaning from them." This type of discussion would also be an appropriate time for teachers and students to use wait time. Use SciLinks for suggestions on other Literacy Skills.

The article More Than One Right Answer has "sentence starters' for the language of argumentation and describes a debrief discussion routine. The authors note that using routines or protocols (such as a Think-Pair-Share) can help students to focus their conversations.

If you and your colleagues have been "arguing" over the role of textbooks and trade books in learning science, the article Bringing Back Books will be relevant. Rather than a dichotomy in which students either engage in inquiry OR read books and other materials, the authors suggest that several programs of research have demonstrated how inquiry-based science experiences combined with science text can support students’ scientific understanding. Their research has demonstrated that "students who experience science through a balance of text and hands-on experiences exhibit greater growth in science knowledge than do students who participate in curriculum involving mainly hands-on inquiry experiences or mainly reading science books." It’s nice to hear that research does support the variety of planned and purposeful learning experiences that teachers use. If your students struggle with reading in science, check out some of the Reading and Writing in Science resources in SciLinks.

Reading about scientists of the past and present may inspire the scientists of the future in our classroooms. But reading biographies does not have to be a dull experience. Check out the suggestions for reading and reflecting on biographies of scientists in this month's Teaching Through Trade Books article. For additional ideas and online biographies, use "biographies" or the name of a particular scientists as a SciLinks keyword.

Having survived a few nor'easters on the mid-Atlantic coast, I was interested in How Can Wind Cause a Bridge to Collapse? I did review some background information on bridges and resonance in SciLinks.

You won't get much of an argument (but perhaps lively argumentation) if you focus on the science behind some familiar topics: pizza (Solar Pizza Friday), skateboarding (Speed Kills! Or Does It?), and Digging Soil. For the last topic, check out the selected Scilinks for Explore Soil and use the search term "soil" for even more information and teaching suggestions.

Interdisciplinary/Integrated Science

Science Scope cover I always look forward to the NSTA journal issues that have a theme with the words integrated or interdisciplinary in them. Interdisciplinary is one of those words that is hard to define, but we "know it when we see it." The article Thinking, Teaching, and Learning Science Outside the Boxes in the February 2009 issue of The Science Teacher does provide a definition as well as a discussion of its importance and even a "taxonomy" of levels of disciplinarity (yes, I know that's not a real word!), showing that it's not an either/or dichotomy. The challenge is to make the connections authentic and purposeful, rather than contrived and trivial.

The lessons described in this issue are anything but contrived and trivial! Solving the Mystery of Mock Mummies goes beyond creating "mummies" as a arts-and-crafts activity to fact-finding on the process of mummification, a study of artifacts, observations, and inferencing. A key component is having to interpret the work of others. In addition to the online resources mentioned in the article, SciLinks has websites under the keyword "archaeology." Although they are in the 9-12 group, some of the sites would be appropriate for middle-schoolers, including Animal Mummies in the Cairo Museum, and In Vesuvius' Shadow. It would be interesting to connect these activities with an ancient history class.

My students were fascinated by amber and the insects inside, and the activities in Amber: Using "Tree Tears Turned to Stone" to Teach Biology, Ecology, and More! would certainly capitalize on that interest. (I also saw this topic as a rationale to visit jewelry stores selling amber for pieces to wear to class!). If your students are interested in more information, try Fossil Amber, Amber: Window to the Past (also recommended in the article), and Oldest Gecko Fossil Ever Found, Entombed in Amber. In Search for the Golden Moon Bear, the authors describe a Reader's Theatre project, in which students wrote and performed an original script based on a science-related book. I've seen many elementary classes use this technique to improve fluency and comprehension, but I'm excited by the idea of middle-schoolers writing and performing, especially if they can share what they're learning with a younger audience. The article has step-by-step directions, but if you need more information, check out the resources at Readers' Theater.

Helping students see the connections between science and "real life" is the theme of several articles. In Cell Towers and Songbirds, students look at the possible consequences of the technology that seems to be indispensible these days. The Global Warming Project could be adapted for high school students with the question: What is the impact of most students driving to school rather than carpooling or using the bus? And Time's Up, Turkey: Pop-up Thermometers takes a look at a technology that will be in use later this month in many homes.

Regardless of what grade level you teacher, two articles would make excellent discussion starters at faculty meetings: The Great Divide: How Mathematics Is Perceived by Students in Math and Science Classrooms shows how there may be confusion between how common concepts (such as data collecting and analysis, graphing, measurement, and unit analysis) are taught and used in science and math classes. And Physics or Stamp Collecting? Pitfalls of the Hierarchy of Disciplines is a thought-provoking article that discusses how we communicate the importance of science to students and some of the misconceptions that students may develop.

How do you use SciLinks?

At the NSTA conference in Minneapolis, last week, I asked a number of teachers how they use SciLinks. Here's Fran Weber's response via Teacher Tube.
 

How do you use SciLinks? What could we do to make it better? Please let us know via comment to this post, or zip me a note -- tbrown@nsta.org.
