NCTM “Students gain insights into their thinking when they present their methods for solving problems, when they justify their reasoning to a classmate or teacher, or when they formulate a question about something that is puzzling them.” (NCTM, 2000)“Students gain insights into their thinking when they present their methods for solving problems, when they justify their reasoning to a classmate or teacher, or when they formulate a question about something that is puzzling them.” (NCTM, 2000)

Texas Essential Knowledge and Skills (6) Underlying mathematical processes. Many processes underlie all content areas in mathematics. As they do mathematics, students continually use problem-solving, computation in problem-solving contexts, language and communication, connections within and outside mathematics, and reasoning, as well as multiple representations, applications and modeling, and justification and proof.

Think Aloud

Objectives: Model the Think Aloud strategyModel the Think Aloud strategy Show how it can be used to help students solve word problemsShow how it can be used to help students solve word problems Show how to expand the Think Aloud strategy to include a written solutionShow how to expand the Think Aloud strategy to include a written solution

What is the Think Aloud strategy? “Think Aloud” is a strategy which includes vocalizing “all of your thoughts, decisions, analyses, and conclusions” when trying to solve a problem or read a text. (Whimbey, 1999)

Meaning “The Think Aloud strategy helps readers think about how they make meaning.”“The Think Aloud strategy helps readers think about how they make meaning.” (Beers, 2003)

My students? Poor problem solvers frequently remark, “either you know the answer to a problem or you don’t know it – you might as well give up or guess”.Poor problem solvers frequently remark, “either you know the answer to a problem or you don’t know it – you might as well give up or guess”. (Whimbey, 1999)

Pair Think Aloud “The THINKER must vocalize very step in her reasoning, and the LISTENER must listen and understand every step the the problem solver takes.”“The THINKER must vocalize very step in her reasoning, and the LISTENER must listen and understand every step the the problem solver takes.” (Whimbey, 1999)

Subvocalize “All the evidence indicates that you should subvocalize freely when you read. It can produce better comprehension of technical material and a fuller appreciation of literary writing where alliteration and other poetic devices depend on hearing the words.”“All the evidence indicates that you should subvocalize freely when you read. It can produce better comprehension of technical material and a fuller appreciation of literary writing where alliteration and other poetic devices depend on hearing the words.” (Whimbey, 1999)

Prediction “ Challenging students to predict the question makes them more curious about what the question will be. When students make predictions they pay closer attention to details and nuances of meaning, which sharpens their thinking and improves their comprehension. For years, experts have advocated the practice of making predictions while reading (Stauffer, 1969; Britton, 1970; Weaver, 1988). The latest research supports prediction-making as an effective learning strategy in any subject area (Nystrand, 1997; Marzano, 2001).”“ Challenging students to predict the question makes them more curious about what the question will be.

Feedback “Every time you are a listener you are learning about problem solving by paying careful attention to what the problem solver does and does not do. Every time you are the problem solver you are indirectly observing the listener who is listening to you. The process has built into it all the feedback you need.”“Every time you are a listener you are learning about problem solving by paying careful attention to what the problem solver does and does not do. Every time you are the problem solver you are indirectly observing the listener who is listening to you. The process has built into it all the feedback you need.” (Whimbey, 1999)

Make it your own “Writing is a way to work yourself into a subject and make it your own.”“Writing is a way to work yourself into a subject and make it your own.” (Zinsser, 1993)

“Just like writing, mathematics requires “gathering, organizing, and clarifying thoughts.”“Just like writing, mathematics requires “gathering, organizing, and clarifying thoughts.” (Burns, 1995)

Writing in math class “The writing students do in math class, however, differs in several ways from much of the writing they do for language arts assignments. Their math writing is typically not creative writing, and having a final product suitable for publication isn’t the goal. Rather, what they write in math class is a way for students to reflect on their learning and communicate their ideas about mathematics.”“The writing students do in math class, however, differs in several ways from much of the writing they do for language arts assignments.

Correct answers aren’t everything “Correct answers can hide a lack of understanding, but writing about the problem- solving strategies used can reveal levels of conceptual understanding.”“Correct answers can hide a lack of understanding, but writing about the problem- solving strategies used can reveal levels of conceptual understanding.” (Goldsby, 2002)

Creating Word Problems “Devising problems based on other problems allows you to see them from the inside out.”“Devising problems based on other problems allows you to see them from the inside out.” (Whimbey, 1999)
