Thinking about Vocabulary March 8 or 9, 2010

2
Don’t forget language barriers other than vocabulary Sentence complexity, active vs. passive “What you have is half of what you need…” ½ cup sugar, 1 and ½ cups of flour, ¾ teaspoon salt, and ¼ teaspoon baking soda were placed in a bowl. If the bowl holds a quart of dry ingredients, how much room is left? Restating in the Think Aloud has real potential here!

3
From homework – Benefits of focus on vocabulary through Think Aloud or similar process Two of the students I had noticed “shutting down” after Step 1 were suddenly more engaged More engagement during this math lesson as a result of providing more vocabulary support This was much more helpful than giving a word, definition, and sheet to label what was happening. I saw a higher level of engagement among the students also. We ended up spending approximately 25 minutes on the vocabulary and context step. This finally seemed to engage the small group.

4
From homework – Benefits of focus on vocabulary through Think Aloud or similar process Their motivation to want to solve the problem really kept their interest enough to want to understand all of the vocabulary used and they asked many questions within their group to help each other process As students became more confident in their vocabulary, they began to take risks and try to figure out the solution

5
Selecting vocabulary As in Think Aloud, students can tell you a lot as they identify important vocabulary. Also important for you to consider and identify vocabulary challenges…

6
From literacy: Considering the challenges ChallengeExample Knows word but has difficulty decoding it guarantee Has concept but not label anguish Does not have concept or label photosynthesis

7
From literacy: Thinking about vocabulary Is the word really critical to understanding the text? (Math: Critical to figuring out the problem?) Is the word likely to be needed again? (Math: Needed in other problems?) Can the students figure the word out on their own? (Math: Can they develop the concept and then add the label without initially having the label?)

Framework from the article Supporting Math Vocabulary Acquisition Context- related Mathematics- related New Review

From homework – Thinking about time and timing for focusing on vocabulary One of the dilemmas presented in the article is that spending time on clarifying vocabulary takes time away from the problem solving itself and in general takes up more time in the class period. To do this approach will be time consuming and much more difficult than lecture and worksheet approach

10
From homework – Thinking about time and timing for focusing on vocabulary Time and presentation of when I did this within a lesson is essential I focused on when to introduce/review the vocabulary The work my students did demonstrates their knowledge of multiples. I think this is a great opportunity to introduce the word multiples.

11
From homework: Challenges in focusing on vocabulary Sometimes I feel I provide too much support in the area of math vocabulary Struggles included the fact that there were so many words and new words that it was hard to pull out the basic math. I think this strategy can be a very useful tool, but don’t know how it would work for them with all new vocabulary.

12
From homework – Insights and thoughts I was also thinking about that I wanted to be sure not to do that may interfere with their mathematical experiences. Holding students accountable for the learning of vocabulary might be equally as important as the “math skill” that is the focus of the lesson. Finding out that the math vocabulary was easier for them to understand than the content vocabulary forced me to think of things I needed to do when giving out problems to solve, mathematical or otherwise Efforts were made to avoid removing language from the task as an accommodation

13
From homework – Insights and thoughts Is it a cure-all? Of course not, but connecting a vocabulary term to a real – life situation at the outset of a problem using a strategy like Marzano is another way to give a student a fighting chance to find success
