THE TEACHING OF
 MATHEMATICS
Nature of Mathematics
     Math is definite, logical and objective. The
 rules for determining the truth or falsity of a
 statement are accepted by all. If there are
 disagreements, it can readily be tested. It is in
 contrast with the subjective characteristics of
 other subjects like literature, social studies and
 the arts.
     Math deals with solving problems. Such
 problems are similar to all other problems anyone
 is confronted with. It consists of: a) defining the
 problem, b) entertaining a tentative guess as the
 solution c) testing the guess, and d) arriving at
 a solution.

             Strategies in Teaching
                  Mathematics


    The strategy for teaching Mathematics
depends on the objectives or goals of the
learning process. In general these goals are
classified into three: a) knowledge and skill
goals, b) understanding goals and c) problem
solving goals.
Strategy Based on Objectives

Knowledge and Skill Goals
      Knowledge and basic skills compose a large part of
  learning in Mathematics. Students may be required to
  memorize facts or to become proficient in using
  algorithms.

Ex. of facts:
        2 X 10= 20   Area of rectangle = B x H
Ex. of skills:
        Multiplying two-digit whole numbers
        Changing a number to scientific notation

       Knowledge and skill goals require automatic
   responses which could be achieved through repetition and
   practice.
Understanding Goals
    The     distinguishing      characteristics    of
 understanding goal is that “understanding must   be
 applied, derived or used to deduce                 a
 consequence”.     Some      strategies    used    in
 understanding are:

     a.   authority teaching
     b.   interaction and discussion
     c.   discovery
     d.   laboratory
     e.   teacher-controlled presentations
a.) Authority teaching
          The teacher as an authority simply
states the concept to be learned. The techniques
used are by telling which is defined, stating an
understanding      without    justification,  by
analogy, and by demonstration.

b.) Interaction and discussion
         Interaction is created by asking
questions in order to provide means for active
instead of passive participation.
c) Discovery
         The elements of a discovery experience
are motivation, a primitive process, an
environment for discovery, an opportunity to make
conjectures and a provision for applying the
generalization.
d) Laboratory
     The advantages are:
     a) maximizes student participation,         b)
provides appropriate level of
difficulty
     c) offers novel approaches
     d) improves attitudes towards mathematics
           This is done through experimental
activities dealing with concrete situations such as
drawing, weighing, averaging and estimating.
Recording, analyzing and checking data enable
students      to   develop    new    concepts   and
understanding effectively.
e) Teacher-controlled presentations
           The teacher uses educational technology
such as films and filmstrips, programmed
materials, and audio materials. Other activities are
listening to resource persons and conducting field
trips. Suitable places for educational trips are
government agencies such as the weather
bureau,       post    office    and     community
supermarkets, factories and transportation centers
like the bus depot and airport.
Problem-solving Goals

     Problem solving is regarded by mathematics
 educators and specialists as the basic
 mathematical     activity.  Other    mathematical
 activities such as generalization, abstraction, and
 concept building are based on problem solving.
 Others believe that the more important roleof
 problem solving in the school curriculum is to
 motivate all students not only those who have a
 special interest in mathematics and a special
 aptitude for it.
Strategies in Teaching
               Mathematics




1. Problem Solving

2. Concept Attainment Strategy

3. Concept Formation Strategy
1. Problem solving

Theoretical Basis for Problem-solving Strategy
 Constructivism – This is based on Brunner’s
  theoretical framework that learning is an active process
  in which learners construct new ideas or concepts
  based upon current/past knowledge.
 Cognitive theory – The cognitive theory encourages
  students’ creativity with the implementation of
  technology such as computer which are used to create
  practice situations.
 Guided Discovery Learning
       Tool engages students in a series of higher order
  thinking skills to solve problems.

 Metacognition Theory
      The field of metacognition process holds that students
  should develop and explore the problem, extend
  solutions, process and develop self-reflection. Problem
  solving must challenge students to think.
 Cooperative learning
       The purpose of cooperative learning group is to make
each member a stronger individual in his/her own right.
Individual accountability is the key to ensuring that all group
members are strengthened by learning cooperatively.
Teachers need to assess how much work each member is
contributing to the group’s work, provide feedback to groups
and individual students, help groups avoid redundant efforts
by members, and make sure that every member is
responsible for the final outcome.
       The favorable outcomes in the use of cooperative
learning is that students are taught cooperative skills such
as: a) forming groups, b) working as a group, c) problem
solving as a group and d) managing differences
Steps of the Problem Solving Strategy

 1. Restate the problem
 2. Select appropriate notation. It can help them recognize a
    solution.
 3. Prepare a drawing, figure or graph. These can help
    understand and visualize the problem.
 4. Identify the wanted, given and needed information.
 5. Determine the operation to be used.
 6. Estimate the answer.

      Knowing what the student should get as the answer to the
  problem will lead the students to the correct operations to use
  and the proper solutions.
7. Solve the problem.
   The student is now ready to work on the problem.
8. Check the solution. Find a way to verify the solutions
in order to experience the process of actually solving the
problem.
Other Techniques in Problem Solving
  1. Obtain the answer by trial and error.
      It requires the student to make a series of
     calculations. In each calculation, an estimate of
     some unknown quantity is used to compute the
     value of a known quantity.

  2. Use an aid, model or sketch.
      A problem could be understood by drawing a
     sketch, folding a piece of paper, cutting a piece
     of string, or making use of some simple aid.
     Using an aid could make the situation real to
     them.
3. Search for a pattern
    This strategy requires the students to examine
   sequences of numbers or geometric objects in
   search of some rule that will allow them to
   extend the sequences indefinitely.

Example: Find the 10th term in a sequence
    that begins, 1, 2, 3, 5, 8, 13, . . . . .
          This approach is an aspect of
           inductive thinking-figuring a rule
         from examples.
4. Elimination Strategy

   This strategy requires the student to use
   logic to reduce the potential list of answers to
   a minimum. Through logic, they throw away
   some potential estimates as unreasonable
   and focus on the reasonable estimates
Concept attainment strategy
    This strategy allows the students to discover
 the essential attributes of a concept. It can
 enhance the students’ skills in (a) separating
 important from unimportant information;        (b)
 searching for patterns and making generalizations;
 and (c) defining and explaining concepts.
Steps
  a. Select a concept and identify its essential
     attributes
  b. Present examples and non-examples of the
     concept
 c. Let students identify or define the concept
     based on its essential attributes
 d. Ask students to generate additional examples
(Sample Activity on Fractions)
Effective use of the concept attainment Strategy

The use of the concept attainment strategy is
  successful when:

 a. students are able to identify the essential
     attributes of the concept
 b. students are able to generate their own examples
 c. students are able to describe the process they
     used to find the essential attributes of the
     concept
Concept Formation Strategy

    This strategy is used when you want the
 students to make connections between and
 among essential elements of the concept:
Steps
  a. Present a particular question or problem.
 b. Ask students to generate data relevant to the
     question or problem.
 c. Allow students to group data with similar
     attributes.
 d. Ask students to label each group of data with
     similar attributes.
 e. Have students explore the relationships
     between and among the groups. They may
     group the data in various ways and some
     groups maybe subsumed in other groups
     based on their attributes.
