Title: Methods of Teaching Secondary Mathematics


1
Methods of Teaching Secondary Mathematics
  • Fall 2007
  • Dr. Marshall Lassak

2
Things to think about
  • Q1 What is mathematics?
  • Q2 What makes mathematics important?
  • Q3 Why do you want to teach mathematics?
  • Q4 How do you want to teach it?

3
Changing ideas about how we learn
4
Constructivism
  • In order to construct your own understanding, you
    must be actively engaged in learning
  • What students learn is connected to how they
    learn it

5
Types of Knowledge
  • Declarative Knowledge
  • definitions, theorems
  • Procedural Knowledge
  • rules, procedures, algorithms
  • instrumental understanding
  • Conceptual Knowledge
  • reasons, relationships, connections
  • relational understanding

6
Types of Teaching Level of Demand
  • Teaching with wonderful explanations
  • Teaching with problem-based tasks
  • Levels of Demand
  • Low-levels
  • High-levels

7
Have you answered questions like these before?
  • Ive decided to count to one million. 1, 2, 3, 4,
    5, ,,,. How long will it take?
  • If you had a million drops of water, would you be
    more likely to
  • drink it?
  • take a bath in it?
  • swim in it?

8
How about these?
  • Does
  • What is a logarithm?
  • Which of the following is ?
  • (a) 5 (b) -5 (c)
  • Why?
  • What is the area formula for a circle?
  • Why?

9
Have you considered
  • What does society expect mathematics education to
    do for our students?
  • Why is it okay (sometimes even funny!) to admit
    I was never very good at math?

10
My Beliefs
  • Mathematics must make sense to students.
  • There are many ways teachers can help students
    make that sense.
  • Fundamental situations, Multiple representations,
    Guided discovery, Interactive lecture,
    Appropriate use of technology
  • You must have time to play with mathematics
  • A wrong answer can sometimes give as much
    information as a right answer.
  • Open-ended questions are typically the best type
    of question.
  • Many paper and pencil methods are becoming relics
    that we continue to cling to because we have yet
    to realize the alternatives.

11
The National Council of Teachers of Mathematics
  • Who is the National Council of Teachers of
    Mathematics (NCTM)?
  • What does the NCTM say about school mathematics?
  • What does NCTM say about Secondary Mathematics
    Teachers?

What Should Secondary School Mathematics Teachers
Know?
  • Undergraduate mathematics
  • Connections between collegiate mathematics and
    high school mathematics
  • What students learn in elementary and middle
    school
  • What mathematics your students will encounter
    upon leaving high school
  • Mathematical maturity that enables and
    encourages continued growth in the subject

13
The NCTMs Principles and Standards for School
Mathematics
  • Standards
  • Content
  • Process

Principles
14
Principles
  • Equity Excellence in mathematics education
    requires equityhigh expectations and strong
    support for all students.
  • Curriculum A curriculum is more than a
    collection of activities. It must be coherent,
    focused on important mathematics, and well
    articulated across the grades.
  • Teaching Effective mathematics teaching requires
    understanding what students know and need to
    learn and then challenging and supporting them to
    learn it well.
  • Learning Students must learn mathematics with
    understanding actively building new knowledge
    from experience and prior knowledge.
  • Assessment Assessment should support the
    learning of important mathematics and furnish
    useful information to both teachers and students.
  • Technology Technology is essential in teaching
    and learning mathematics it influences the
    mathematics that is taught and enhances students
    learning.

15
Standards
  • Content Standards
  • Number and operations
  • Algebra
  • Geometry
  • Measurement
  • Data analysis and probability
  • Process Standards
  • Problem solving
  • Reasoning and proof
  • Communication
  • Connections
  • Representations

16
The Content Standards
17
Understanding about the pedagogy that the NCTM
proposes
  • The Principles and Standards advocate increased
    use of contextualized problems that ground
    learning mathematics in real-world situations.
  • Thus, reform-oriented teachers have students
    solve problems individually, in pairs, or in
    small groups. The students then share
    solutionsincluding representationsthat may be
    questioned and analyzed by peers (and the
    teacher).
  • Such pedagogy results in a proliferation of
    representations Students create idiosyncratic
    representations, draw on conventional
    representations, and blend idiosyncratic and
    conventional representations as they solve
    contextualized problems.

18
Standards-based Reform
  • The bottom line is that standards-based reform
    appears to work when it is implemented as part of
    a coherent systemic effort in which curriculum,
    assessment, and professional development are
    aligned.
