To Read Stuff You Have to Know Stuff: Helping Students Build and Use Prior Knowledge

Rate this book
In the age of click-and-go reading, why do students need to know information when they can just look things up?

Bestselling author Kelly Gallagher argues that to think critically, it’s imperative that we teach kids stuff. Lots of it. Why? Because students who know more are able to read more, and read better.

In To Read Stuff You Have to Know Stuff, Kelly draws from his own teaching practice to share the importance of building students’ prior knowledge at four

How building knowledge helps students to overcome word poverty Sentences and How building knowledge helps students to comprehend “small” reading How building knowledge helps students to critically read articles—an important skill in our digital age How building knowledge moves students away from fake reading and back into reading full-length books To Read Stuff You Have to Know Stuff also shows how students can monitor their own comprehension. They can see that many reading difficulties aren't the result of not being a "good reader"—they simply lack knowledge.

Our students are fortunate to live in an age where so much information is a click away. But to read well—and think well—they need to own that knowledge.

I always find myself nodding my head when reading this author’s books, as I did when I saw him in person at a PD session. This book connected with everything I believe to be true about teaching literacy, and gave me some great ideas for doing so. This is a solid teaching resource.

I love a Kelly Gallagher book on teaching. I (always) find myself inspired and mind-blown. If you're a teacher of adolescents, and you're not reading KG's books, you're missing out.

Kelly argues that to think critically, it’s imperative to teach kids stuff. Lots of it. Why? Because students who know more are able to read more, and read better. He identifies the assumptions that many make, primarily that teachers can just tell kids to read and they will do it, and that students can just look things up when they don’t know something. He then gives a very "hands-on" approach to the teaching of reading, starting with word work and moving through passages and finally to whole novels. This step-by-step approach helps kids build the knowledge they need to be successful readers.
As usual, Kelly goes to some of his favorite sources, other leaders in the field of education (past and present): Penny Kittle, Kylene Beers, Bob Probst, Tom Newkirk. Be he also draws from his own teaching practice to share the importance of building students’ prior knowledge. Building knowledge helps students to overcome word poverty, to comprehend “small” reading, to critically read articles—an important skill in our digital age, and moves students away from fake reading and back into reading full-length books. Kids are fortunate to live in an age where so much information is a click away. But to read well—and think well—they need to learn to monitor their own comprehension and see that many reading difficulties aren't the result of not being a "good reader"— they simply lack knowledge.
This is a great book for all types of educators and takes a lot of Gallagher's specific focus on literacy in the English classroom and applies it in a way that is accessible to other subjects. For those who are familiar with Kelly’s work, you will not be surprised when he makes connections to baseball or crime dramas, but be prepared for him to express his opinion vociferously about censorship, diverse literature, and educational policy. His work inspires me, but I do not agree with all of his ideas. 4

Gallagher does it again. This is an excellent book that ironically and frustratingly does not have an e-book format despite having an audiobook format. Get with the times Gallagher!

This is a great book for all types of educators and takes a lot of Gallagher's specific focus on literacy in the English classroom and applies it in a way that is accessible to other subjects, which is definitely a large gap in educational literature currently.

Attached are my notes:

"Reading in front of kids must be a performance"

David Doctorman - what is the next best thing to learn?

Blough "What does it say what does it mean why does it matter?"

Knowledge is the primary driver of comprehension

Ch 1 key points
Students who know more are able to read easier. Read more. Think about at a deeper level because can make connections

Ch 2
Owning words makes it easier to connect sith new learning

B: Word nerds
Scholastic's kids and family reading report 2010-2019 " a rise in... infrequent readers"

B: Rosenblats: literature is exploration

10-15 times to learn a word with various exposure. Timothy Shanahan

Knowledge of a word is a memory residue of several meaningful encounters with it in diverse contexts

Bid idea 3: we learn words im waves

If you are learning one word you are really learning many words

Developing 'reading allegiance'

Book clubs centered around a theme or idea
Ex: y8 who am i?
Effron divided
The prince and the dress maker
The crossover

Y9 how does identity change?
Miles morales
Speak a graphic novel

Ch 3: Sentence construction activities



Ch 5: When do kids stop defining themselves as readers? Will and skill

Ch 6 Can not know deeply without prior knowledge

This is an important text to read for all educators and gives solid theory and advice and guidance in "helping students build and use prior knowledge". First, the organization and illustrative and font choices make it the least boring professional text. Second, it doesn't overwrite any of the concepts Gallagher is sharing. He gives information, solid examples, help, citations and then moves on to the next topic.

The delivery is solid. And it's a necessary conversation because it's so true. Kids do not have the kind of prior knowledge to be able to read stuff. Period. Building that can include things like an article of the week. It's challenging them to engage with the information they do know to be able to say that they are the ones with the deficit and it's not the "writer's fault" that they didn't understand what they were reading, then HOW to move forward from that.

I pulled so much from this text to be able to talk about and apply!

I first want to say that I am a huge Kelly Gallagher fan. I've read everything he's written. I've seen him speak. And if I'm being completely honest, I wish I could write WITH him to make his work more transferable for those of us who work in the world of high school special education. For me, and perhaps it is because I'm so familiar with his work, this book wasn't something I chose to keep. Is it filled with wonderful ideas? Yes. Does it reference a large amount of other works to look into? Also, yes. I was hoping to see more strategies and applications rather than references to previous works, etc. I don't know why... I was just hoping for more.

One of the best Professional Development books I've read in a long time. Kelly gives a very "hands-on" approach to the teaching of reading and the assumptions that many teachers make that we can just tell kids to read and they will do it. Starting with word work and moving through passages and finally to whole novels, this step-by-step approach helps kids build the knowledge they need to be successful readers.

I will always adore Kelly Gallagher, but this latest book didn’t pack the same punch as 180 Days. It makes its case well, and it is well organized— know words, know sentences, know background info, know whole texts)— but it’s not as packed with plans and specific texts as I longed for. I also think some of the research cited feels old.

As usual with Gallagher's work, it is relevant, creative, compelling, and quite honestly, "doable" within classrooms. His ideas are simple, yet have complex outcomes if implemented and used well. Makes me want to get back into the classroom a little bit...

Read this and attended Gallagher’s webinar on the book. So thankful for clear guidance that cuts through all the distractions and noise in teaching. It is validating and enlightening at the same time. The work of literacy is a steady drumbeat—onward march!

Not only does Kelly do a wonderful job teaching me strategies that I should implement in my classroom, but he is one of the only PD authors that can keep me engaged! His comments are entertaining as well as educational!

Great ideas in the book. I didn’t enjoy the author’s little snippy, biased political examples.

A book with a legend: in the teaching world, Kelly Gallagher is a legend and this is his new book. I found this book to be super insightful and it supported practices I already have in my arsenal of teaching ideas and strategies. We all learn more if we have base of knowledge to grow from. Gallagher has a list of themes for books clubs 7-12 with suggested titles for each theme - which I fully plan to use in 12th next year. He also has grammar ideas, reading ideas, articles of the week and word of the day, and writing ideas that I can’t wait to try!
“Only 14% of students read books for pleasure weekly.”
This statistic shocked me - only 62% college grad rate in 2023!
“Notes by hand = learn and remember more” - justification when kids ask why we have to do handwritten notes
“It would take 22 years to adequately teach the k-12 standards”
