Expectations and clearing up confusion This webinar focuses on CCGPS content specific to Unit 5, Coordinate Algebra and Accelerated Coordinate Algebra/Analytic Geometry A. For information about CCGPS across a single grade span, please access the list of recorded GPB sessions on Georgiastandards.org. For information on the Standards for Mathematical Practice, please access the list of recorded Blackboard sessions from Fall 2011 on GeorgiaStandards.org. CCGPS is taught and assessed from 2012-2013 and beyond. A list of resources will be provided at the end of this webinar and these documents are posted in the 9-10 wiki. http://ccgpsmathematics9-10.wikispaces.com/

4
Expectations and clearing up confusion The intent of this webinar is to bring awareness to: the types of tasks that are contained within the unit. your conceptual understanding of the mathematics in this unit. approaches to the tasks which provide deeper learning situations for your students. We will not be working through each task during this webinar.

5
Welcome! Thank you for taking the time to join us in this discussion of Unit 5. At the end of today’s session you should have at least 3 takeaways: the big idea of Unit 5 something to think about…some food for thought how might I support student problem solving? what is my conceptual understanding of the material in this unit? a list of resources and support available for CCGPS mathematics

6
Welcome! Please provide feedback at the end of today’s session. Feedback helps us become better teachers and learners. Feedback helps as we develop the remaining unit-by-unit webinars. Please visit http://ccgpsmathematics9-10.wikispaces.com/ to share your feedback..http://ccgpsmathematics9-10.wikispaces.com/ After reviewing the remaining units, please contact us with content area focus/format suggestions for future webinars.

Welcome! For today’s session have you: read the mathematics CCGPS? read the unit and worked through the tasks in the unit? downloaded and saved the documents from this session? Ask questions and share resources/ideas for the common good. Bookmark and become active in the 9-10 wiki. If you are still wondering what a wiki is, we will discuss this near the end of the session.

Misconception?

9
What do we do with mistakes and misconceptions? Avoid them whenever possible? "If I warn learners about the misconceptions as I teach, they are less likely to happen. Prevention is better than cure.” Use them as learning opportunities? "I actively encourage learners to make mistakes and to learn from them.”

10
Diagnostic teaching. Source: Swann, M : Gaining diagnostic teaching skills: helping students learn from mistakes and misconceptions, Shell Centre publications “ Traditionally, the teacher with the textbook explains and demonstrates, while the students imitate; if the student makes mistakes the teacher explains again. This procedure is not effective in preventing... misconceptions or in removing [them]. Diagnostic teaching..... depends on the student taking much more responsibility for their own understanding, being willing and able to articulate their own lines of thought and to discuss them in the classroom”.

12
Misconceptions It is important to realize that inevitably students will develop misconceptions… Askew and Wiliam 1995; Leinwand, 2010; NCTM, 1995; Shulman, 1996

13
Misconceptions Therefore it is important to have strategies for identifying, remedying, as well as for avoiding misconceptions. Leinwand, 2010; Swan 2001; NBPTS, 1998; NCTM, 1995; Shulman, 1986;

14
Importance of Dealing with Misconceptions 1) Teaching is more effective when misconceptions are identified, challenged, and ameliorated. 2) Pupils face internal cognitive distress when some external idea, process, or rule conflicts with their existing mental schema. 3) Research evidence suggests that the resolutions of these cognitive conflicts through discussion leads to effective learning.

15
Some principles to consider Encourage learners to explore misconceptions through discussion. Focus discussion on known difficulties and challenging questions. Encourage a variety of viewpoints and interpretations to emerge. Ask questions that create a tension or ‘cognitive conflict' that needs to be resolved. Provide meaningful feedback. Provide opportunities for developing new ideas and concepts, and for consolidation.

What’s the big idea? Overview Key Standards Enduring Understandings Essential Questions Strategies for Teaching & Learning

19
What’s the big idea? Develop a deep understanding of definitions of basic geometric figures (angle, circle, perpendicular line, parallel line, and line segment) Deepen understanding of transformations in the plane.

Assessment

37
Suggestions for getting started: Read the unit and work through the tasks with your colleagues. The only way to gain deep understanding is to work through each task. Make note of where, when, and what the big ideas are. Discuss the focus and coherence of the unit. Make note of where, when, and what the pitfalls might be. Look for additional tools/ideas you want to use. Determine any changes which might need to be made to make this work for your students. Share, ask, and collaborate on the wiki. http://ccgpsmathematics9-10.wikispaces.com/
