Description:
Teacher training programs rarely offer practice explaining mathematical concepts. Who has time to listen to 30 students explain the same idea? Using online learning environments and screencasts, preservice teachers can practice, critique, revise, and improve explanations while solidifying content knowledge.

Level: 5-9
General Session


Suzanne

Erin

Description:
Are you looking for ideas to help your students make sense of problems, persevere in solving them and improve their math communication skills? We'll explore free resources from the Math Forum, including the Technology Problems of the Week, and hear accounts from classroom teachers who have been effectively using these resources in their classrooms.

Objectives:

Participate in activities that:
  • demonstrate problem-solving prompts (tPoWs) to use in a one-computer classroom or a computer lab
  • keep students on task and engaged in problem solving
  • use technology to help you learn more about your students' mathematical understanding
  • help make a shift from a teacher-led to a student-centered focus as students become more comfortable with problem solving and communication
  • get students to the analysis level of questioning so that they are thinking critically

Focus on Math:
The Math Forum @ Drexel has been reflecting on mathematical practices since 1992. Our Technology Problems of the Week are freely accessible problem-solving challenges that take advantage of interactive math tools and encourage students to construct viable arguments. Students are able to draft their solutions, receive feedback from the teacher, reflect on their work, and revise their work using this online environment designed to help them make sense of problems and persevere in solving them.

Session 497
PCC, Room 125
Level: 3-12
General Session


Jason

Description:
Professional communities are a crucial resource for teachers, however they are notoriously difficult to create and sustain. Participating teachers and university facilitators will discuss how Internet and other learning technologies can be used to create a virtual community that bridges professional development and instructional practices.

Objectives:

  • Introduce structure of the online community (history, goals, activities)
  • Explore technology supports, including blogs, discussion boards, shared whiteboards, and multimedia podcasts, that allow teachers from different schools to explore and discuss dynamic representations of mathematics
  • Discuss examples of community-based professional development and shifts in instructional practices
  • Learn about opportunities to participate in future activities or create your own virtual communities.

Focus on Math:
Community participants (teachers) will share examples from their own experiences that were supported by community activities (content foci will include algebra, functions, analysis). Presentation will also highlight the ways the group-supported efforts to incorporate their new knowledge and technology in their own classrooms.

Jason

Description:
Lesson study is a proven, powerful tool for valuing and enhancing teachers’ professional growth that usually requires whole school buy-in. Join us as we share our successful support of professional learning in a virtual environment. Meet teachers from different schools who participate in lesson study activities to enhance student learning.

Objectives:
Our goals are to enhance participants understanding of lesson study (history, goals, activities), while exploring the design of online lesson study and its future as compared to Japanese lesson study. We will demonstrate technology supports, i.e., asynchronous interactions (blogs, discussion boards), synchronous interaction and collaboration, and video (mini-camcorders) to document student interaction and learning, while deepening teachers’ knowledge of students’ mathematical thinking.

Focus on Math:
We will share examples of lesson study activities, teacher research and student thinking, understanding, and artifacts while engaged in functions, quadratic equations, proportional reasoning and transformations. Actual lesson study teachers will engage participants in the process of better developing student understanding of complex mathematical concepts.

Session Resources and Handouts

Description:
Heard all the hype about Twitter? Wondering how it's helped math teachers improve their practice? Thinking about developing your own personal learning network? Skeptical that anything can be communicated in 140 characters? In this workshop I'll share stories and tips on using Twitter to build a community to support your professional development.

Objectives:
See examples of math problems and topics shared on Twitter. See examples of teachers supporting each other to improv teaching on Twitter. Learn about other math folks who are on Twitter and how to engage in Twitter conversations, including who to follow. Learn some of the Twitter lingo so you can tweet like a pro from day one. Discuss other social media technologies and other ways to build a virtual personal learning network. Discuss ways students might benefit from using Twitter.

Focus on Math:
People share math on Twitter every day! Whether it's a teacher in rural Canada collecting instant weather data from around the world, students learning about polling techniques by asking questions through Twitter and Google Docs, or the questions, numbers, and math facts of the day shared by organizations like NCTM, there's a lot of content in the Twitter -verse. We'll look at examples of math shared on Twitter as well as how Twitter has enhanced teachers' lessons and content knowledge.

Using Technology to Increase Conceptual Understanding in Algebra and Geometry

Annie Fetter

Friday, April 27, 2012
3:30 pm - 4:30 pm
Session 610
Marriott, Salon D
Level: 6-12
General Session


Annie

Description:
Many topics in algebra and geometry are difficult to address conceptually and tend to be taught procedurally. We’ll explore interactive applets that let students "notice and wonder", talk about mathematical situations, and develop conceptual understandings of triangle properties, linear equations, systems of equations, and factoring trinomials.

Objectives:
Participants will

  • try the Math Forum's Noticing and Wondering problem solving strategy.
  • experience ways to coordinate the development of "concept" in the "concept, method, procedure" continuum.
  • explore applets and prompts that help all students make connections to math ideas, such as properties of geometric shapes and linear and quadratic relationships, that then serve as foundations for learning more advanced mathematics.
  • learn ways to use these ideas to increase math talk in the classroom.

Focus on Math:
We'll look at different types of triangles dynamically, focusing on relationships between angles and side lengths and not just vocabulary and laundry lists of properties. We'll explore two applets, a running race and a vending machine, that generate data that can be used to develop an understanding of linear relationships and strategies for solving systems of equations. Multiplying and factoring polynomials with the area model will be explored using dynamic algebra tiles (in a FOIL-free zone!).

Free Tools: Financial Education, Math, & Problem Solving

Valerie Klein

Saturday, April 28, 2012
9:30 am - 10:30 am
Session 665
PCC, Room 113 A
Level: 6-12
General Session


Val

Description:
Financial ideas can be complicated to model and difficult to understand. Given the role fine print plays in video game rentals, credit card agreements, car loans, and more, it is important for students to learn about financial ideas early (and often). We share technology that allows students to explore at the overlap of math and financial concepts.

Objectives:

  • Share free resources that are cataloged by mathematical and financial topic
  • Demonstrate how to incorporate these tools into lessons and align them with the common core state standards
  • Share lesson plans that make use of these technological tools
  • Share teachers' experiences with these tools

Focus on Math:
There's a nice overlap between financial and mathematical content. The presenter will share free tools that are aligned with middle and high school content. She will also share ideas for how to use them within existing math concepts such as how to examine credit card repayment in algebra or algebra two courses and how to explore inflation and the cost of particular items over time in 6th and 7th grade math.
