September Publications and SciLinks

Each month, I’ll mention some sites that relate to that month’s themes of the three K-12 NSTA journals. These are sites that illustrate what I think is a good use of the technology.

Science and Children – Animals – I’d certainly like to show younger students that there are many interesting animals in addition to the dinosaurs!

History and Biology of the Horseshoe Crab
This site shows how a clean design and chunking of the text and other features work together in to create a user-friendly site. This is appropriate for younger students, but older ones will find the information interesting as well. I spend a great deal of time on the Delaware beaches and my community is a horseshoe crab sanctuary – and yet I learned a lot from this site myself!

Classifying Critters
Anything from the Howard Hughes Medical Institute is a quality site, in my experience! This is part of a really nice site for younger students on using physical characteristics to classify animals, and one I might use with the whole class. This could lead to interesting discussions.

Critter Guide
I like this one for older elementary or middle school students, in that it is a very browseable, searchable site with interesting pictures and information that is well organized. (My one criticism would be the use of Marine Life as a category, when the other categories are based on physical characteristics).

Science Scope – Reading – This is an area of professional interest to me. Reading in the science classroom was the focus of my graduate work, and I loved being able to help students learn how to read nonfiction, such as science textbooks and magazine articles (and now websites) in my classes.

Building Big
I was impressed at how this site combines text and graphics in a browseable format that lets the user pursue topics of interest. But the Build-a-Bridge feature focuses on using what has been read to create structures in an interactive segment, and the users then get feedback on their designs (and a timely topic given the issues of infrastructure after this summer’s event in Minnesota). I’ve found that most PBS sites are excellent and can be used independently of their programs.

Classroom Exploration of Oceans
These explorations have beautiful photographs and real-life stories about scientists and their studies. NOAA has an amazing number of quality sites.

Windows to the Universe
In SciLinks, there are many components of this site entered in the database separately. What appeals to me as a middle school teacher is the fact that there are three levels of text: beginner, intermediate, and advanced. Sometimes the amount of information differs from level to level, and other times the text is chunked differently. Nevertheless, the site can be personalized to the student.

The Science Teacher – Weather and Climate – I’ve just finished up monitoring a summer program that had teachers creating weather maps and learning about climate change. I hope they have access to sites such as these.

Weather
This site looks at the relationship between the oceans and weather. What I like here is the section for educators that has suggestions on how to use this site in a classroom.

Weather World 2010 Project
In SciLinks, there are many individual components of this site in the database. For me, I’d save money on meteorology textbooks and use this site instead (and channel the textbook budget into purchasing a weather station!). It’s written in an interesting style so that teachers can use it for their own background knowledge, too, or teachers can use the section on “Projects and Activities.”

Weather and Climate Basics
This is a good site to let students read about the differences between weather and climate. It’s full of really good graphics.

To see many other SciLinks sites, go to www.scilinks.org. If you’re not registered, login as a Guest to check out what’s here. Or use your NSTA member number to login, or you can register (free) as a teacher/parent.

From Cyberspace to Scilinks: Content and Credibility

How does a website become part of SciLinks? Potential topics are identified from the content of SciLinked textbooks or NSTA publications. (The SciLinks homepage has a list of textbooks). Sites are then selected from the database, or spotters are asked to search the web for potential sites. All sites in the database have been through a review process that includes a rubric.

Reviewing the Sites - Content

The vast majority of sites suggested and screened by the spotters are included in SciLinks. Some get higher ratings than others. I’ve taught classes in web design at the high school and college level, and over the years, I’ve seen improvements in design, either because we’re more design-savvy or because the technology is getting better. My personal guideline is “Would I want my students spending their time with this site?”

I certainly want our students to have access to accurate content. One of the first sites I reviewed noted that “the tide comes in in the morning and goes out at night.” Needless to say, this site did not make it into SciLinks! But the SciLinks spotters are good at filtering out sites with incorrect information.

I also want our students to have access to interesting and meaningful content. In my state, the reading tests show weaknesses in reading and interpreting nonfiction or informational text (aka “expository text") at all grade levels. Here is where SciLinks can provide a wealth of good content reading. However, one of my concerns is with sites geared to younger students. I think sometimes that we adults don’t quite get it. Some sites are designed to be cute, with dancing earthworms and talking spiders. The research on reading shows that students have an interest in nonfiction, so why do site developers continue to decorate their sites with cartoonish graphics (rather than photographs or accurate drawings) or try to be “with-it” by using teenage slang, which becomes outdated very quickly? Another component of many sites for younger learners is the “fun” link that often leads to coloring pages, mazes, or find-a-word puzzles. In an era when the time for science classes is shrinking to accommodate more time for reading and math, I don’t think I would use precious class time for activities that have little science in them. Not that these wouldn’t be perhaps OK for indoor recess or take-home packets (not graded homework, though), but even then, there are so many other activities that are both enjoyable and meaningful (and now I’m off my personal soapbox!).

The SciLinks sites also provide a way to extend what is in your textbook for interested students. One criticism of American science textbooks is that they do not treat topics in depth. The SciLinks websites can supplement textbook topics with additional information and features such as animations, graphics, and video clips. Sometimes the sites reiterate basic textbook information. I think that’s OK – some students may need to see the information displayed in a different format or with different graphics to understand. I know one elementary teacher who puts the 10-year-old textbooks on the shelf and uses nonfiction trade books and web resources to implement the school’s science curriculum!

Many of the sites have links for teacher resources. These include suggestions for incorporating the site into science lessons, hands-on activities, and inquiry learning. The sites also are correlated to the National Science Education Standards (NSES). Although the states have their own lists of standards, most are reflected in the NSES, perhaps in different terminology.

Each month in this blog, I’ll describe a few components of the rubric we use to evaluate the sites.

Reviewing the Sites - Credibility

Assuming that the content of the site seems correct, the site moves to the review process with its rubric. Two of the categories deal with the credibility of the site. The reviewers look at a site’s “Authority.” In general, sites from colleges and universities (and their professors), scientific and environmental agencies (including NOAA, NASA, USGS), other research agencies, museums and libraries, and zoological parks and botanical gardens rate high in this category. Some commercial sites are free of sales pitches and are very good; those that are basically commercials or sales pitches for products or services are not included. Personal sites probably do not rate as high, unless the author notes his or her credentials and includes sources with the site.

Having a way to contact the site developer via e-mail is part of the “Collaboration” category. Giving users the opportunity to contact the author with questions or feedback adds to the site's credibility. Another form of collaboration occurs when the site fosters communication and dialog between users (to date, this has not been very common).

I’m not sure we have a decision on whether to include articles from wikis, blogs, or YouTube. I know there are teachers that discourage students from using these as formal sources of information, especially if they cite no sources for the information. Any thoughts?

No matter how reputable the site’s author, the design of the site is what captures our attention. I’ll describe this part of the rubric next month.
