Satellite Movies or DVD Movies?

The Smith family is trying to decide between installing a satellite dish and receiving and movies through the satellite or purchasing a DVD and signing up for DVD rentals per month. The Smiths need to compare the cost of each option over several months in order to make an appropriate decision.

– SatelliteSatellite: • One time installation of $29$29 and $49$49 per month

for the service that allows them to unlimited access to their choice of movies with the stipulation that they must maintain this system for at least one year.

– DVDDVD: • Purchase a DVD player for $250$250 and unlimited

rental of DVDs for $30$30 per month.

Help them make a decision

Possible Approaches

Symbolic approach– Satellite = $29 + $49 (# of months)– DVD = $250 + $30 (# of months)

So…

$250 + $20( # of months) = $29 + $49(# of months)

# of months = 11.63

Mathematics ContentLife is too short for long division!

Understanding patterns, relations, and functions– Represent, analyze, and generalize a variety of patterns with tables, graphs, words,

and when possible, symbolic rules;

– Relate and compare different forms of representation for a relationship

– Identify functions as linear or nonlinear and contrast their properties from tables, graphs, or equations

» NCTM, 2000, Algebra Standard for Grades 6-8

Analyze change in various contexts– Use graphs to analyze the nature of changes in quantities in linear relationships

» NCTM, 2000, Algebra Standard for Grades 6-8

Understand how mathematical ideas interconnect and build on one another to produce a coherent whole

» NCTM, 2000, Connection Standard for Grades 6-8

Select, apply, and translate among mathematical representations to solve problems

TechnologyI think there is a world market for maybe five computers.

Watson, 1943

Technology is essential in teaching and learning mathematics; it influences the mathematics that is taught and enhances students’ learning …The study of algebra need not be limited to simple situations in which symbolic manipulation is relatively straightforward. Using technological tools, students can reason about more general issues, such as parameter changes, and they can model and solve complex problem that were heretofore inaccessible to them … Spreadsheets offer a useful tool for posing worthwhile problems … When technological tools are available students can focus on decision making, reflection, reasoning, and problem solving.

» NCTM, 2000, The Technology Principle

The computational and graphical capabilities of current technologies enables users to efficiently generate and manipulate a variety of representations of mathematics ideas and processes. Activities that engage students in connecting multiple representations (e.g., graphical, numerical, algebraic, and verbal), and those that invite students to analyze or create images, visualizations, and simulations provide wide-ranging opportunities for mathematical exploration and sense-making.

» AMTE, 2006, Technology Position Statement: Preparing Teacher to Use Technology to Enhance the Learning of Mathematics

Promoting technology-literate students using technology as an integral component or tool for learning within the context of the subject… use spreadsheets as productivity tools, research tools and problem-solving and decision making tools.

PedagogyHope is not a strategy

~Thomas McInerney

Effective mathematics teaching requires understanding what students know and need to learn and then challenging and supporting them to learn it well. It requires:

– reflection and continual efforts to seek improvement– serious commitment to the development of students’ understanding of mathematics– challenging and supportive classroom environment– observing students, listening carefully to their idea and explanations, having mathematical goals, and using the information

to make instructional decision» NCTM, 2000, The Teaching Principle

The kinds of experiences teachers provide clearly play a major role in determining the extent and quality of students’ learning. Students understanding of mathematical ideas can be built throughout their school years if they actively engage in tasks and experiences design to deepen and connect their knowledge.

» NCTM, 2000, The Learning Principle

The effective use of technology in the mathematics classroom depends on the teacher» NCTM, 2000, The Technology Principle

Teachers need to have a strong pedagogical knowledge base related to the effective use of technology to improve mathematics teaching and learning.

» AMTE, 2006, Technology Position Statement: Preparing Teacher to Use Technology to Enhance the Learning of Mathematics

Teachers need to incorporate new strategies, analyzing the potential benefits of technology: Student-centered instruction, collaborative work, active inquiry-based learning, critical thinking and informed decision-making.

» National Educational Technology Standards for Students, 2000

Teacher need to apply technology to develop students’ higher-order skills and creativity.» National Educational Technology Standards for Teachers, 2002

Key Questions!!

What knowledge and skills do mathematics teachers need to teach with technologies such as spreadsheets?How do they gain this if they are already teaching?

If we teach today as we taught yesterday, then we rob our children of

tomorrow. ~John Dewey

Central Components of TPCK (Adapted from Grossman’s (1989, 1990) components of PCK, revised for TPCK by Niess, 2005)

Teacher demonstrates knowledge and beliefs consistent with:– an overarching conception about the purposes for incorporating technology in teaching

mathematics • What the teacher knows and believes about the nature of mathematics, what is important for students to

learn, and how technology supports learning mathematics are keys to the teacher’s knowledge and beliefs about teaching mathematics with technology in ways that serve as a basis for decisions about classroom instruction (objective, strategies, assignments, curriculum ad text, and evaluation of student learning);

– knowledge of students’ understandings, thinking, and learning in mathematics with technology • Teacher relies on and operates from knowledge about how students learn mathematics with technologies

and believes that technologies are useful in learning appropriate mathematics;

– knowledge of curriculum and curricular materials that integrate technology in learning and teaching mathematics • Teacher discusses and implements various technologies available for teaching particular topics and how

the topics and ideas in a technology-enhanced environment with concern for how the activities are organized, scaffolded, structured, and assessed throughout the curriculum; and

– knowledge of instructional strategies and representations for teaching and learning mathematics with technologies• Teacher adapts mathematical representations with technologies in multiple ways to meet specific

instructional goals and the needs of the breadth of learners in the class.

Page 15: Maggie Niess Oregon State University oregonstate/~niessm niessm@onid.orst

Question for Discussion

What are the affordances and constraints with professional development framed by:

– Spreadsheet operations and concepts - developed through multiple mathematics topics such as

• Dynamic and dependable spreadsheets?• Creating formulas and charting?

– Planning and designing learning environments and experiences • with key mathematics topics - variables, visualization and representations?• with one mathematics unit - such as linear functions?• scaffolding learning about spreadsheets while concurrently learning mathematics concepts?

– Teaching, learning and the mathematics curriculum • focused on managing student learning activities in a spreadsheet-enhanced environment?• Focused on applying spreadsheets to develop students’ higher order skills and creativity?

– Assessment and evaluation of mathematics learning• focused on a variety of assessments techniques for applying spreadsheets in assessing

student learning?

Page 16: Maggie Niess Oregon State University oregonstate/~niessm niessm@onid.orst

Question for Discussion

What operations and concepts support spreadsheets as dynamic and dependable tools for learning mathematics?– Avoid numeric values in formulas (=sum(B2:B10)/8)– Refer to values by cell referencing (=sum(B2:B10)/B1)– Use built in formulas (=average(B2:B10))– Be careful with cell referencing (absolute vs. relative)

(=$B$3*B5+$C$3)– Linking table information to charting
