Institute for Student Achievement PROMOTING QUANTITATIVE LITERACY Quantitative Literacy: The ability to make sense of quantitative representations by identifying, accounting for, and making new meaning of them in various contexts across all disciplines. Purpose: In an increasingly complex and data-driven world, a well-educated student needs access to ways of making quantitative sense of the written word. One strategy for achieving this goal is the development of quantitative literacy. This involves making sense of quantitative representations by identifying, accounting for, and making new meaning of them in various contexts across all disciplines. Identifying… Students should be able to identify numerical representations included in the text. Accounting… Next, students should be able to account for the representations by organizing them in some meaningful way. Making New Meaning… At its highest level, students will be able to make new meaning which includes drawing conclusions, making inferences and posing questions for extended investigations. On the pages that follow, the three levels of quantitative literacy are further differentiated. In addition, we have included three levels of recommended “teacher” questions. The first set is questions about the text. The second set of questions was designed to help students engage in thinking that goes beyond the text. The final set supports student understanding of their questions and conjectures. 1 Quantitative Literacy Rubric For the Students… Identifying... Numeric representations within context Language within context Making New Meaning Of... Accounting For… Organizing or grouping Looking for patterns Conjecturing (inference with imagination or speculation) causes with attempt to make meaning Mathematical relationships within context Computing Comprehension of terms Formulating questions or conjectures for further investigation Draw conclusion based on the perceived implications of the quantities Attempt to connect it to unidentified causes or the data's social or political implications Identify possible contradictions Investigating if the claim of the source holds true for their context Creation of alternative representations to see the data from another angle Consider how different representations of quantities affect the perceptions of the information 2 Student Demonstrations of Quantitative Literacy The table below presents specific things you may see your students doing to demonstrate that they are engaging in strategies that support the development of their quantitative literacy. Student Demonstrations of Identifying Student Demonstrations of Accounting For Highlighting, circling, underlying terms, phrases, data, or relationships Computing change over time between related situations Making observations Read cited sources Isolating the quantitative aspects in the source Articulate connections between quantities Convert quantities to similar units Student Demonstrations of Making New Meaning Formulating new questions Investigation of new information in cited sources or other sources of information to improve conjecture Connecting the quantities to broader social, political, and ethical issues Create a list of quantities Creation of graphs and/or tables Some students may see quantities as present and others will see the relationships within the context Checking quantities for validity of supportive argument Calculate differences between the quantities under consideration Articulating thoughts on the causes leading to further research Presenting possible next steps to remedy or advance the issue Engage in discourse with others 3 For the Teacher... Identifying Scan for potential paragraphs students would use to validate context Identify potential words that might help or hurt students as they read Accounting For Help students take on text and break it into manageable pieces Observe how students are making sense of and interpreting the document and how will I use that inform next steps Checking to see the connection students are making from what they identified and how are they organizing their thoughts Make New Meaning Of Asking students to use the information within the article to come up with their own conjectures Asking students to formulate ideas that would help them defend their position Asking students to formulate new questions for further investigation based on their reading of the text Help students build skills to look at outside resources as a means of presenting an idea or promote a new point not in the article Helping students enter into a discussion about items they have identified as important Helping to guide students in defining terms with meaning (is what they say what they mean?) 4 Quantitative Literacy Teacher Questions The table below presents questions that you as the teacher may want to ask your students to support their development of quantitative literacy. Questions the teacher should be asking about the text: What argument is the author of this article making? Find the numeric representations in the text. How are they related? Do the mathematical expressions connect to the argument that is being made? How? Are the mathematical expressions consistent with the argument that is being made? How? Do the mathematical expressions provide evidence for the argument? How? Do the mathematical expressions impact the conclusions? How? Is the argument strengthened or weakened by the quantitative presentations and how? What other mathematical expressions (arguments) could you make that would strengthen the article’s thesis? How can the mathematical expressions be translated to deepen understanding? What are the social, political or ethical implications? Questions the teacher should be asking that go beyond the text: About questions the students have Based on your quantitative and qualitative analysis of the text, what new question would you like to investigate? What information do you need to gather to help you answer that question? Where are you going to get that information? How are you going to use quantitative data to help answer your question? Questions about conjectures the students make What conjectures can you make from your analysis of the reading? What would you do to investigate the validity of your conjecture? What information do you need to gather to prove or disprove your conjecture? Where are you going to get that information? What type of quantitative representation would best help you prove or disprove your conjecture? 5
