Abstract
This paper articulated who an experimental mathematics teacher is. A teacher who istrained to teach mathematics and who has the skills and competence needed to carryout the task effectively. Unfortunately the department has been saturated withunqualified teachers who are specialists in other disciplines like chemistry, physics,economics, engineering etc. The paper however, describes the dimensions of anexperimental mathematics teacher as teacher’s personality, knowledge of the subjectand methodology which play a role in the teaching and learning of mathematics. Thepaper also identified and explained the modern methods of teaching mathematics.These are problem solving, cooperate/group, computer assisted instruction, andinteractive method. It recommended, among others, that government and schoolauthorities should engage the services of qualified teachers of mathematics andprovide appropriate teaching and learning equipment/facilities. Also, it is important forteachers to identify with professional organizations so as to meet the challenges of thefast growing trends.
INTRODUCTION
Research findings have confirmed the dearth of mathematics
teachers at all level of education in the country. Obioma (2005)
has drawn attention to the depreciating capacities of mathematics
teachers, observing that the old generations of mathematics
experts were fast disappearing and where there were any
replacements at all, younger persons who had little or no
guidance in the profession and research generally dominated the
skyline. The lack of enough teachers to handle the subject
particularly at the secondary level has led to borrowing teachers
who are specialists in other disciplines like chemistry, physics,
economics, engineering etc. to teach mathematics. In many cases,
such borrowed teachers are not professional teachers because they
are not trained teachers. Hence, they lack the skills, competence
and the teaching methods required to teach mathematics
effectively. Usually, such teachers avoid the teaching of some
topics which they find difficult to handle. In essence, it means
that short supply of qualified teachers leads to mathematics
teaching been handled by incompetent hands who in turn can only
produce poorly bred mathematics students. The students therefore
become victim of poor teaching. This trend confirms the assertion
by Fakuade (1973) that a shortage of suitably qualified teaching
staff will result in poor teaching which invariably will result
in a production of another generation of poor students.
Freudenthal (1991) maintained that to learn mathematics means to
engage in the process of mathematising through which mathematics
is re-invented. His emphasis on mathematising carries a strong
evolutionary stance and is further elaborated subsequently by
Wittmann (2001) who proposed that mathematics education should be
viewed and studied as a ‘systemic evolutionary design science’.
He also proposed that the study of teaching units called
substantial learning environments should form the core of
mathematics education. “The design of substantial learning
environments around long-term curricular strands should be placed
at the very centre of mathematics education. Research,
development and teacher education should be consciously related
to them in a systematic way (Wittmann, 2001).
Experimental Mathematics Teacher
From research evidence, econometric analyses have equivocally
demonstrated that, some teachers are dramatically more effective
than others and that these differences have lasting effects on
student learning (Rivkin, Hanusahek, and Kain, 2005). The teacher
is the most indispensable factor in effective administration of
any educational system. Also, it has been established that no
amount of resources put into the nation educational system,
without adequately prepared and motivated teachers, nothing
tangible can ever be achieved from the system. The role of
teachers at all levels of education is emphasized in the National
Policy on Education (FRN, 2004) that no educational system may
rise above the quality of its teachers. This declaration in the
policy document underscores the need for teachers’ effectiveness
in teaching and learning. Eso (1998) conceptualized teachers’
effectiveness as the managerial skills essential for enhancing
classroom control and discipline. It is the teachers’ competence,
ability, resourcefulness, and ingenuity through effective
utilization of appropriate language, methodology and available
instructional materials that could bring out the best from the
learners in term of academic achievement. But what makes a great
teacher? Some people are of the opinion that teachers are born.
But Ukeje (1991) is of the view that teachers may be born but a
good teacher is born and made. Maduabum (2009) explained that,
this is because teaching is both an art and a science”. Some
aspects of the art of teaching may be innate, but the science of
teaching has to be cultivated Maduabum (1986) had argued that
having knowledge and transmitting knowledge are two different
things. Some people have both abilities but many do not. The
‘born teacher’ exists but he is a rare bird! (Maduabum, 2009).
However, ability to transmit can be acquired if one is not lucky
enough to be born with it. Adepoju (1995) categorized these
teachers into four categories, they are:
a) Those who know mathematics but do not know how to teach it
b) Those who know how to teach mathematics but do not know much
mathematics
c) Those who do not know mathematics and do not know how to
teach it
d) Those who know mathematics and know how to teach it.
With these categories of teachers in the school system there is
the need for professional competence among teachers, so that
teachers can be confident in doing their job while helping
students learn mathematics.
Ezenweni (2002) define an experimental mathematics teacher as a
teacher trained to teach mathematics as a science to secondary
school students. That is, the teachers use different teaching
method to reduce the persistent problem of mathematics
abstractness and in a null shell, an experimental mathematics
teacher is a lover of mathematics.
An example will be helpful to illustrate a pedagogy -caused
student difficulty. Tanner (2000) states that teachers
generally use “fruit and salad approach” to introduce the
addition of two algebraic expressions, such as, 2a+3b in
algebra teaching. This kind of expression is often explained
to students by teachers through the use of some materials,
such as 2 apples and 3 bananas. However, Pimm (1987), as
cited in Tirosh, puts forward reservations regarding this
approach, warns against its potential role in causing
learning difficulties for students and notes that it leads
to confusion between a being apples and a being the number
of apples. The algebraic expression is not an analog of 5
apples, nor is 5 apples a possible interpretation of 5a, the
letters themselves are standing for numbers. In fact, some
studies have shown the disadvantages of using this approach
in introducing algebraic expressions. Booth (1988), for
example, shows that some students thought that the
expression 2a + 5b is equal to 7ab on the grounds that 2
apples plus 5 bananas is 7 apples-and bananas. Tirosh,
(1998) also point out that this approach may lead students
to think algebraic expressions, such as 2a and 3b, cannot be
multiplied, that is one cannot multiply apples and bananas.
All these suggest that sometimes the way materials are used and
the way the teaching is conducted can be the causes of, or at
least play a role in the emergence of student learning
difficulties for mathematical concepts.
Fennema and Franke (1992) argue that if a teacher has a
conceptual understanding of mathematics, this influences
classroom instruction in a positive way, therefore, it is
important to have mathematics knowledge for teachers. Teachers’
interrelated knowledge is very important as well as procedural
rules. They also emphasize the importance of knowledge of
mathematical representations, because mathematics is seen as a
composition of a large set of highly related abstractions. They
also stated that ‘if teachers do not know how to translate those
abstractions into a form that enables learners to relate the
mathematics to what they already know, they will not learn with
understanding’.
Traditional indicators of teacher quality, such as educational
level and certification, do not predict student outcomes (Rivkin,
Hanushek, and Kain 2005), certain aspects of teacher education
are relevant. For example, mathematics teachers who have
completed PhD course work in mathematics and an advanced
certificate course in Education are more effective than peer
teachers without such advanced training in education. An
experimental mathematics teacher should be able to use modern
methods of teaching and learning in order to bring out a
desirable outcome (Ezenweani, 2002). He outlined the
characteristics of experimental teachers to include the
following:
1. They are emotionally balanced
2. They are active and never lazy
3. They are cognitively balanced
4. They are mentally healthy and ready to find solutions to
problems
5. They are friendly to all people and see things from other
people’s point of view to learn on their part
6. They are very enthusiastic in academic work
7. They are cultured in dealing with issues affecting human
relations
8. To avoid the bad characteristics generally identified in
them, they are supposed to be neat in appearance all the
time, become more careful the way they dress and careful in
the choice of vocabulary and expression. They should avoid
being harsh to students and speak clearly not only to the
students but in public
9. They are supposed to be creative in their experimental
pursuit which should make for some originality in their
activities and findings.
Here are three dimensions of an experimental mathematics teacher
they are:
Teachers personality
Knowledge of the subject matter
methodology
Teachers Personality
The teacher’s personality is one of the characteristics to look
for in the teaching and learning of mathematics. Anybody can
become a teacher, but it takes special person to be a great
experimental teacher. He/she must rise above the crowd and make
empathy, enthusiasm, creativity, dedication, and discipline in
the process of teaching.
Knowledge of the subject
The knowledge of an experimental mathematics teacher are defined
as the skills effectively and efficiently acquired when teaching
mathematics. That is, the ability to organize and teach in
interesting and flexible ways. Knowledge of the subject matter
content is vital for the experimental teacher. It determines the
line of activity the teacher should follow to achieve the desired
objective and being acquainted with the content to be taught.
Methodology
The learning of mathematics depends on the way it is presented to
the learner, the way the learner actively interacts with the
learning experiences presented to him and the environment within
which the learning takes place. With the current increase in
scientific knowledge, much demand is placed and emphasis is laid
on the teacher, the learner and the environment in the whole
process of teaching and learning of mathematics. Today’s
mathematics teachers are experiencing major changes not only in
the mathematics content they teach, but also in the way they
teach.
Modern Method of Teaching Mathematics
Problem solving method: This approach is characterized by the
teacher in helping students to construct a deep understanding of
mathematical ideas and processes by engaging them in doing
mathematics: creating, conjecturing, exploring and testing.
Polya’s (1965) describe problem solving processes into four
stages:
1) understand and explore the problem
2) find a strategy
3) use the strategy to solve the problem
4) Look back and reflect to the solution.
Alio and Harbor-Peter (2000) recommended that polya’s problem
solving strategy should be used by secondary school mathematics
teacher to teach mathematics. The learning of mathematics in this
case proceeds from the concrete to the abstract. Approaching
mathematics through problem solving can create a context which
stimulates real life and therefore justifies the mathematics
rather than treating it at the end.
Cooperate / Group method: Cooperate learning method of teaching
is an instructional strategy that simultaneously addresses
academic and social skill learning by students. It is one way of
providing students with a well-defined framework from which to
learn from each other. Cooperate method of teaching is a team
approach where the success of the group depends upon everyone
pulling his or her weight. Group members share the various roles
and the interdependent in achieving the group learning goal.
Cooperate learning can take place in a variety of circumstance.
For instance brainstorming and tutorial group, when employed as
instructional strategy provides opportunity to develop
cooperative learning skills and attitudes
Computer Assisted Instruction: this approach uses computer as a
substitute for the teacher, that is, the students interacts with
the computer directly, usually as a terminal. Although the
teacher is involved in planning the system and supervising it’s
operation, a well-planned system frees the teacher from routine
teaching tasks, so that he may spend more time in working closely
with individual students (Odili, 2006). NCTM (2000) asserted
that educational technology (computer) can help teach content. It
can offer students a bridge from concrete to abstract thinking,
enabling them to observe and create multiple representations of
mathematical ideas. For instance, students can use geometric
instruction software to investigate the relationship between
circumference and diameter of a circle (Agwagah, 2013).
Interacting method: Interactive method of teaching includes
giving students something to do and getting what they have done,
so that you can decide what would be best to do next. If a
teacher asks questions in class, gives assignment, and check
homework then you are already teaching interactively. Interactive
instruction relies on discussion and sharing among participants
which allows for a range of groupings and interactive method.
Interactive method requires the refinement of observation,
listening, interpersonal and intervention skill and abilities by
both teachers and students
Teachers Development Programs
Effective instruction in school is defined through teacher
education program, which is the key towards understanding the
knowledge and skills of teaching and learning (Ololube, 2005a,
2005b). The education of pre-service and in-service science
teachers is meant to help individual teacher grow and develop as
a person, provide him or her with the skills and professional
abilities to motivate children to learn, assist them in acquiring
the right types of understandings, concepts, values and attitudes
to manage classroom instruction and be productive members of the
society in which they are born, grow and live (Lawal, 2003).
If mathematics teaching is to be effective, the pre-service
training of teachers must be very sound, while they also need to
be exposed to in-service training at regular intervals. Where
teacher preparation is inadequate it will lead to teaching
failure in the classroom; this is an area that needs to be
improved upon. Teacher development is considered particularly
effective, when teachers are in charge of the agenda and
determine the focus and nature of the programming offered (Ball,
1996). This concur with, the FRN (2004) National Policy on
education stipulates that teacher education shall continue to
take cognizance of changes in methodology and in curriculum.
Furthermore, that teacher shall be regularly exposed to
innovations in their profession (p 34). Fennema, Carpenter, Levi
and Franke (1998) learned that engaging teachers in current
reforms requires more than showing them how to implement
effective practices. Hence the government agencies are committed
to development and training of teachers which is aimed at
increasing the ability of the individual and groups to contribute
to organizational effectiveness.
Conclusion
Experimental mathematics teachers are key determinants of
mathematics learning outcomes. The learning of mathematics
depends on the way it is presented to the learners, the way the
learners actively interact with the learning experiences
presented to them. With the current increase in scientific
knowledge, emphasis is laid on the teacher in the whole process
of teaching and learning of mathematics. The Teachers
personality, knowledge of the subject, and methodology play a
significant role in the mind-set of students towards the learning
of mathematics. All these factors could also be applicable to
mathematics learning since mathematics is regarded as the
language of science. It is on this premise that the mind-set of
the teacher’s disposition to the subject, students, and classroom
environment could make or mar the mind-set of the students
towards the learning of mathematics. Hence the mathematics
teacher should be psychologically prepared to teach the subject
efficiently.
Recommendations
It is important for mathematics teachers to identify with
professional organizations so as to meet the challenges of the
fast growing trends. Such as, Mathematical Association of Nigeria
(MAN), Science Teacher Association of Nigeria (STAN), Curriculum
Organization of Nigeria (CON), and African Mathematical Union
(AMU) etc. Government and school authorities should engage the
services of qualified teachers of mathematics and provide
appropriate teaching and learning equipment/facilities. The state
government should as a matter of urgency send mathematics
teachers for training and seminars for effective teaching of
mathematics, particularly in our primary and secondary schools.
Teachers should try as much as possible to relate their lesson to
real life situation in order to reduce abstract nature of the
subject.
