Building Content Area Reading Skills: Anticipation Guides

A few weeks ago, I wrote about exploring nominalizations as a tool for helping readers to understand content area texts. Today, I'll be writing about a teaching tool for content area texts--anticipation guides.

Anticipation guides are tools that help readers to consider the propositions in a text before, during, and after reading. Simply put, the teacher creates 4-7 statements related to the big ideas in a text. Students rate whether they agree or disagree with each statement before reading, and then reflect again after reading. 

There are lots of resources available for creating anticipation guides. Here is the overview from ReadWriteThink, but a simple search will yield many more. Interestingly, each resource shows a slightly different twist on the anticipation guide--which I really like! I am always wary of educational approaches which must be implemented under exact conditions to be effective.

Vocabulary Preview + Anticipation Guide
In the example to the right, you can see how I've combined a vocabulary preview with the anticipation guide. The text is an introduction to decomposers, and there were key words that I wanted students to be able to read and understand. 

Students read this text with a partner, and it was interesting to observe the conversations that arose. Some pairs read the entire text first before going back to the text to consider the statements, while others considered each statement as they read. I suspect that preferred methods has something to do with working memory capacity...difficult to prove in the classroom, but intriguing to consider! Whichever method was chosen, students were carefully considering details and main ideas in the text and matching them up to prior knowledge--really important processes.

Column Headers--Consider Carefully!
Many of the widely available anticipation guides focus on the affective statements which can be interpreted and argued in multiple ways. As I work with fourth graders, I like to use a mixture of affective and factual statements. When I do this, I use the column headers "Yes" and "No" instead of "Agree" and "Disagree".

The guide to the left goes with Follow the Water from Brook to Ocean, one of my favorite picture books for teaching about water and watersheds. I chose statements that would direct student attention to some of the key vocabulary in the text, such as the word reservoir, and some key ideas in the text, such as the movement of water.




Unit Anticipation Guides
A unit anticipation guide can work to bring focus to a series of connected texts. This Antarctica anticipation guide was one of my favorite tools over many years. As we read and explored the topic, students referred back to the anticipation guide again and again, talking about which statements were supported by texts and which they were still curious about. 

The Eraser Game
Will students erase their first answers? Yup. It's frustrating at first to see students erasing their "Before Reading" replies to make them all correct. Students want to be right, and they want to be able to say that they knew it all before the text.

The Eraser Game goes away with careful modeling and cushioning. I like to talk about how great it is to learn from texts--"I didn't know that before, and now I do!" In fact, a change of answer from beginning to end is to be celebrated. That's what reading is all about! (It takes a bit for this lesson to sink in, of course.)

How often?
Any good instructional tool can become overused. As Graham Nuthall put it, "...when students experience a narrow range of classroom activities they rapidly lose the ability to distinguish one activity from another in memory. As a consequence, they lose the ability to recall the curriculum content embedded in those activities." 

I'm very careful to not overuse such a meaningful tool, and I use anticipation guides about once or twice per unit, or every 3-4 texts. 

As you can see, anticipation guides are great tools to help students get engaged in content area texts.

Paths to Paraphrasing

Last week, as part of our nonfiction study, we looked at how to paraphrase sentences. Paraphrasing is the process of putting ideas from the text into your own words.  It's an important skill, one that is used across the content areas as students write summaries, take notes, and answer questions about text.

But teaching paraphrasing is tough! In order to paraphrase, readers need to have two basic skills:

Being able to replace words with synonyms-This means that readers need to have a wide range of vocabulary. When paraphrasing nonfiction, readers especially need to understand general academic vocabulary.

Being able to rearrange sentences-Readers need to be able to change the order of sentences and ideas.

Both of these are hard for fourth graders. Our first step is to look at how we can rearrange sentences. I showed students a sentence with an underlined prepositional phrase.

At the South Pole, no plants can grow.

We looked at how we could move the prepositional phrase around the sentence. Then we tried one that was a little longer:

The seas around Antarctica are filled with tiny plants called phytoplankton.

Of course, just moving around a prepositional phrase isn't paraphrasing. So then we looked at how we could replace words with synonyms:

The United States operates three research stations in Antarctica.

What words could we use to replace the word "operates"? Students came up with several that work--runs, keeps, has. Then we looked at what words we couldn't change in the sentence, like research stations. This phrase has a very specific meaning with no real synonyms. This also highlights the role of background knowledge in paraphrasing. When kids have well-developed knowledge about the topic, they have a better idea of what can be replaced and what needs to be kept.

Finally, kids tried to put it all together to paraphrase a few sentences. It takes some time to teach, but students respond well to the instruction. When we work on summarizing after the holiday break, our task will be much easier.

Looking for help with paraphrasing? Here are some ideas:

1. Work with students to develop their academic vocabulary. The Academic Word List by Averil Coxhead is a great resource for this.

2. Show students how to move ideas around in sentences. This could fit in during writing instruction or even handwriting time.

3. Work with sentences that relate to content. Kids need to have some background knowledge about the topic in order to paraphrase successfully. In fact, when readers are having trouble paraphrasing, that's a good indicator that comprehension just isn't happening!

Reading Nonfiction: Dealing with Faulty Prior Knowledge

Reading about Antarctica creates the perfect situation to help students learn more about how to change their prior knowledge. In general, readers don't like to change their ideas. With students, this means that they often cling to faulty prior knowledge.

Kids have many faulty ideas about Antarctica. Most of them think that polar bears do eat penguins, that lots of snow falls in Antarctica, and that there's no need for sunglasses or sunscreen. How do I help them to change these ideas while reading nonfiction?

Back when I was doing research for The Forest and the Trees, I came across the work of Graham Nuthall. He was an amazing researcher, taking hours of classroom footage, coding it, and interviewing students weeks and months later to find out what they remembered and why. In a 1999 article, he explained the kinds of activities that students need to engage in to make rich connections:

"This evidence suggests that tasks need to be set up that model and give students practice in activities that involve making connections between related pieces of information and identifying implications and potential differences and contradictions. As students practice these activities and become expert in the habits of mind involved in the activities, these habits become internalized and an unconscious but automatic part of the ways their minds deal with new experiences." (Nuthall 1999)

So I can't just sit the kids down and say, "Hey, kids. Guess what? Polar bears don't eat penguins." Instead, I need to build situations that create an internal mismatch in students' schemas, so that they experience the feeling of resolving this conflict. Our Antarctica readings are perfect for this.

Is it working? Listen to what a student said on Friday: "I know that there aren't any plants at the South Pole. And if there are no plants, there can't be any animals, right? So why is there a research station there? What would they study*?"

This student was putting together related bits of information and identifying the conflict. What great thinking! This is the payoff from reading multiple texts on the same topic--kids have the time and space to think about what fits, and what doesn't.

*We'll be reading about the South Pole this week. While there aren't any animals, there is some interesting research...

Teaching Nonfiction: Antarctica

As the cold winds begin to howl, I like to bring an assortment of texts about Antarctica into the classroom. Antarctica is a great fit for fourth grade for several reasons:

Shared knowledge building-My students don't have much prior knowledge about Antarctica. As we learn about it, then, we can experience the feeling of adding to our schemas together. It's fascinating to see how kids pick up on new words and share their experiences. For example, the word "skuas" came up in two different texts. A skua is a kind of bird that lives in Antarctica, but most students had never heard of it before. When one student found a picture of a skua in a book, the others were eager to see it--I overhead one say, "Oh! A skua is a bird!"

As we read multiple texts, then, we all can experience adding to what we know. Students filled out an anticipation guide at the beginning of the unit. Then, after each text, we go back to see if our thinking has changed. Sometimes, what we find is surprising, like the fact that visitors to Antarctica need to wear sunglasses and sunscreen!

Interesting texts-In the Toolkit Texts from Heinemann, there is a nice nonfiction first-person piece about doing research at Palmer Station, as well as a map of Antarctica. (By the way, the map is available as a free sample on the website.) These texts started my unit. Since then, I've found additional books. Jennifer Owings Dewey's Four Months at the Bottom of the World is a nice example of personal journal text, while the Magic Treehouse Penguins and Antarctica book gives kids a thorough introduction to the continent.

Online resources-This blog is documenting the LTER Cruise that is about to begin for the new season. LTER means Long-Term Ecological Research, and these scientists return to the same places each year to see how things have changed. At this link, you can find other resources. And there are plenty of videos as well. When I have written to researchers with questions, they have responded...how neat!

Penguins and other cool animals- My students are fascinated by penguins each year. They like to pore over the encyclopedia of penguins that I check out of the local library, look at the names of the different types, and find out where they live. Not all penguins live in Antarctica, which is surprising for many of the students.

Antarctica is also home to some interesting invertebrates, like sea spiders and carnivorous sponges. (My students this year are especially intrigued by the carnivorous sponges. One said, "That's like my worst nightmare come true! A meat-eating sponge!")

My interest-When I started working with this topic, I knew very little about it. This helps to keep me interested! I admit to following the research season to try to learn more each year. I've learned all about the IceCube project at the South Pole and figured out how to tell the different kinds of penguins apart. This year, I want to try more of the resources from PolarTREC.

No matter what the topic, reading a series of interconnected texts helps students to make sense of nonfiction. Next week, kids are eager to read more about Antarctica--and I'm eager to help them!
