Abstract :
A standard based mathematics education is very much essential for the
knowledge-based economy of any country. In this era, the study of
mathematics has become significant. In the early years of schooling, lack
of proper guidance, insufficient mathematical skills and misconceptions
of mathematical concepts may yield serious learning deficiencies and
improper problem solving skills. This study was conducted to find out
the effectiveness of expository and problem-solving approach in the
subject of mathematics on the academic achievement of secondary
school students of district D. G. Khan. The purpose of this study was to
find whether problem solving approach is much better and effective than
the expository strategy in the subject of mathematics at secondary school
level. The population of the study consisted of all secondary schools
students of Tehsil D .G .Khan. A sample of forty (40) students from
grade 10thwas selected through convenient sampling. The sample was
equally divided into experimental and control group on the basis of result
of Pre-Test. The Pre-test, post-test equivalent group design was used for
the study. Data was analyzed by two-tailed t-test. Data analysis revealed
that experimental group that was taught by problem solving approach
scored significantly better than the control group that was taught by
expository strategy showing effectiveness of problem solving approach
over expository strategy in teaching of Mathematics.
