Strengthening mathematics-instruction
This document describes a mathematics instruction workshop that is 18-24 hours long and consists of 8 modules. The workshop focuses on increasing the cognitive complexity of mathematical problems and improving instructional practices. It is standards-based and covers content for Algebra 1, Geometry, Algebra 2 and Pre-Calculus. The workshop is designed for teacher practice and implementation of lesson study between sessions. Participating teachers found that the workshop provided a starting point to improve their instruction by exploring complex problems and strategies to help students think more deeply about mathematical concepts.

- 8. Locating Cognitively ComplexProblems 1. Choose a section or chapter in your textbook that you will be teaching in the next few weeks. 2. Use post-it notes to indicate any problems that are cognitively complex. 3. At your table, discuss the following questions: • Where did you find these problems? • Compare the number of complex problems to the number of standard problems in your textbook. • How often do you assign these problems for homework? • How often do you include these problems in your section/chapter assessments?

Using the activity page: • Determine the basic structure for each of the problems. • Determine which problems were easier and harder for you and why. • Share your “AHA’s” with each other.
- 12. It gave mea starting point to improve instruction… Working with my fellow teachers and having time to explore complexity was most valuable… Learning about cognitive layering in problems is very important… I learned to ask more open-ended questions and use “what if” to explore mathematical ideas without fear This workshop showed me strategies to help students think mathematically… What teachers said about a pilot workshop
Editor's Notes
- #2 Instructor’s Notes: Depending on when this module is presented, you may want to revisit the group meeting norms, expectations, etc.
- #3 Instructor’s Notes: 20 minutes total Slide 1 of 3 This is a two part activity. The first is done individually, the second as a group. Each person is to think about the things that they feel contribute to low proficiency in student work (such as lack of basic skills as indicated on the slide) and write each idea on a post-it note. (Slide 1) Each table groups the individual ideas into broad categories, i.e., clusters and makes a poster with categories on color post-its. (Slide 2) You will facilitate a discussion on commonalities and differences and compare the final product to Slide 3. Materials needed: Small post-it notes for each participant Large poster of diagram for each group Engagement/Process Strategies Closing the Window Finger Minutes Process as Given, Process as Understood
- #4 Instructor’s Notes:1 minutes Explain to participants that the highlighted outcomes are the ones that we will be working on in this module. We will always be reviewing instructional and engagement strategies.
- #5 Instructor Notes: 1 minute This slide sets the stage for the module and some of the topics that we will be looking at in future modules. Tie these ideas back to the brainstorm that the participants did during “Setting the Stage.” This is an animated slide. The slide appears without the bottom cog on the left, then the cog blinks four times, and then it stays on the slide. This was done for emphasis.
- #6 Instructor’s Notes:10 minutes This is the first introduction to the module topic. This is not a definitive list. There are other characteristics that teachers might refer to. You may elicit additional responses and place them on chart paper for future reference. Emphasize that “cognitively complex” does not equate with “a word problem,” a problem with very large numbers or a tedious repetition of the same algorithm (such as long division with ten terms). You will need to go in depth for each of these bullets. Ask questions of your participants for clarification, understanding, etc. You will be referring to these characteristics often in all of the modules. Engagement/Process Strategies Brainstorm

- #8 Instructor’s Notes:Slide 3 of 3 In the following slides, try to elicit suggestions from participants as to what has caused the level of complexity to increase. Refer back to the TIMMS study and why these problems are different. Lower complexity: All procedures are standard algorithms Higher complexity: Involves abstractions, alternative forms of representation Requires student to make connections between different representations Ask participants to suggest additional terms that would make this question applicable to Algebra 2/Precal concepts. Suggestions might include ln x, ex e 3lnx

- #12 Instructor’s Notes:15 minutes Have participants partner with someone they haven’t worked with before to discuss the questions with their partner. You might want to ask for comments from the whole group as closure to this activity. You should try to keep the conversations positive and focused on how to make this work, rather than “My kids won’t be able to do this” or “It’s too hard” or “I don’t have the time to do this” Engagement/Process Strategies Adapt the A/B Each Teach strategy Adapt the Assumptions Inquiry strategy Most Important Point ” strategy Finger Minutes ” strategy Processes Given, Process as Understood ” strategy Adapt the “Say Something” strategy Closing the Window strategy Materials Indentifying structures page
