Overview

This material is based upon work supported by the National Science Foundation under Grant No. ESI-0628122.

Why Data Literacy?

“We use data every day—to choose medications or health practices, to decide on a place to live, or to make judgments about education policy and practice. The newspapers and TV news are full of data about nutrition, side effects of popular drugs, and polls for current elections. Surely there is valuable information here, but how do you judge the reliability of what you read, see, or hear? This is no trivial skill—and we are not preparing students to make these critical and subtle distinctions.”

-- Andee Rubin

Develop a modular, interdisciplinary middle school unit, consisting of a series of four subject area modules that:

support deep student understanding of standards-based content & processes in four disciplines: Social Studies, Mathematics, Science, & English Language Arts.

use real-world data across the disciplines, allowing students to engage in key aspects of data literacy both within & across the disciplines.

are based on recent & robust findings in cognition & instruction, & specifically address the notion of transfer across the curriculum (PFL).

Integrate digital tools to support learning across modules.

Create a set of assessments that measure student growth in data literacy as well as unique disciplinary approaches to it.

Goals & Objectives

Standards-Based Content

Data literacy requirement

MS standards– SS (NCSS)

MS standards– math (NCTM)

MS standards– science (NSES)

MS standards– ELA (NCTE)

Formulate and answer data-

based questions

“Formulate historical questions, obtain data, question &identify gaps in data & construct sound interpretations”

“Formulate questions, design studies & collect data about characteristics shared by 2 populations, or different characteristics within 1 population”

“Identify questions that can be answered through scientific investigations; develop the ability to refine & refocus broad & ill-defined questions”

“Conduct research on issues & interests by generating ideas & questions & posing problems”

Use appropriate data, tools, &

representations

“Use appropriate geographical tools such as atlases, database systems, charts, graphs & maps to generate, manipulate & interpret information”

“Select, create & use appropriate graphical representations of data; discuss & understand the correspondence between data sets & their representations”

“Use appropriate tools & techniques to gather, analyze & interpret data, guided by the question asked & the investigations designed”

“Gather, evaluate & synthesize data from a variety of sources to communicate discoveries in ways that suit their purpose & audience”

Develop and evaluate data-

based inferences & explanations

“Encourage increasingly abstract thought as learners use data & apply skills in analyzing human behavior in relation to physical & cultural environments.”

“Use observations about differences between 2 or more samples to make conjectures about populations, formulate new questions, & studies to answer them”

“Formulate questions, design & execute investigations, interpret data, use evidence to generate explanations; propose alteratives & critique explanations & procedures”

“Use spoken, written & visual language to accomplish purposes (eg. learning, enjoyment, persuasion & exchange of information)”

Unit Context: World Water Issues

Water Use in the Tigris-Euphrates Basin(SS, Math, Science)

and in the United States (ELA)

"The Earth, with its diverse and abundant life forms, including over six billion humans, is facing a serious water crisis. All the signs suggest that it is getting worse and will continue to do so, unless corrective action is taken. The crisis is one of governance, essentially caused by the ways in which humans have mismanaged water.”

Pedagogical Approach: PFL

•A focus on “people’s abilities to to learn in knowledge-rich environments”

•“Rather than evaluate whether people can generate a finished product, the focus shifts to whether they are prepared to learn to solve new problems”

Bransford & Schwartz. (2001). Rethinking Transfer: A Simple Proposal With Multiple Implications.

Pedagogical Approach: PFL

preparing students to learn in one curricular context (SS),

with formal learning occurring in another (Math), &

extending the PFL approach to include application (Science) &

communication activities (ELA).

Technology and Data Literacy

Knowing how to use digital and connected technology has become an ever-increasing part of being literate, as technology has become the “pen and paper of our time, … the lens through which we experience much of our world”

-- Warlick, 2006

Large generalizations about ‘digital kids’ and their affinity for new styles of learning have a pernicious consequence – they can blind us to the actual literacy gaps that exist in children’s use of digital media. If using digital tools well actually places cognitive demands on children that they need help with, we’d better attend to and address them…. We are beginning to recognize that the literacy demands of common media tools vary according to the purpose to which they are put.

--Tally, 2007

Use of Digital Technology in the Modules

What we could/should use vs

What the reality of school imposes

How do we deal most effectively with this tension, without shortchanging learners?

How much choice can/should we provide as part of the basic unit? Or should this just be a consideration for module extensions?

What are the literacy demands that the use of digital technologies for learning puts on students?

Use of Digital Technology in the Modules

Emphasis on simple tools (for a variety of reasons, including access and scalability)

•Internet-based materials•Word processor•PowerPoint for content delivery•Spreadsheets•Digital maps

Fostering Data Literacy Across the Curriculum

Requires:•input from across the disciplines, allowing each teacher to remain a content expert•but not imposing responsibility for teaching a new discipline (data literacy) on teachers

Our approach:•Investigate a complex, engaging, real-world problem•Social studies sets the context•Math is used for quantitative analysis•Science investigates the context from a scientific perspective, building upon analyses conducted in math•ELA has students explore issues emerging from the data and communicate positions regarding these

Conclusions (Lessons Learned So Far)

• Data literacy is a part of all aspects of our lives, including education. It is important to teach, but not easy to do.

• Teaching it across the curriculum may help in this matter.

• Integrating digital tools creates opportunities for rich experiences for data literacy (variety of resources; data manipulation in multiple formats; media creation).

• Integrating digital tools creates challenges (students’ and teachers’ technology literacy levels; access).
