Abstract English has been recognized as important language in Pakistan like many other counties of the world
and used for academic, research, communication, business and official purposes. It has been taught as compulsory
subject up to graduation level. The students at all levels and especially secondary level try to have competency in
English language skills particularly writing skill; being more important as used for evaluation of their academic
achievements. But they feel difficulty to acquire competency because of many reasons; the conventional teaching
method being used as one of the causes. New pedagogical methods like Problem Based Learning need to be
experimented in Pakistani situations as it has been proved a successful pedagogy in many contexts around the world
[8]. PBL as pedagogy is a teaching-learning method where students work in learner-centered classroom environment
in small groups of 4-5 confronting the authentic problems given by the teacher and find their solutions by discussing
among themselves generally in three class meetings. They work more at home by studying and searching for the
solutions. The present study was an attempt to experiment PBL learning of English writing skill through English
essay writing on secondary level students at IMCBIP (Islamabad Model College for Boys, Sector G-7/4 Islamabad,
Pakistan) and to see effectiveness of PBL in comparison of that of conventional lecture method. The study was
conducted by using pretest-posttest control group experimental design with the subjects (20+20 experimental &
control groups) and data were analyzed by employing t-test and descriptive statistics. The findings showed that PBL
was more effective pedagogy than conventional lecture method for improving English writing skill of secondary
level students.

1. Introduction
English has been recognized as an important language
because of its wider use as lingua franca, as medium of
instruction, knowledge, research and social status in the
world as well as in Pakistan. People deem it essential for
better prospects and mobility, and endeavor to accomplish
competency in communication. Despite all these, students
at all levels face difficulties to acquire and use it for
academic and daily pursuits. The difficulties multiply for
secondary level students especially for their written
communication because of a number of reasons; English
being a second language pose hurdles for them as
conventional lecture methods emphasize only on the usage
of language rather than its use. In most of the cases, the
secondary level students learn English at schools only and
have rare chances of its use at their homes. They depend
on rote learning and reproduce in examinations what they
have memorized earlier; free expression is rarely
encouraged in their academic life. Though many teachers
and researchers have been trying out new methods and
techniques to improve the situation, yet there is lot more
to do in this regard.
Problem Based Learning has been experimented as
pedagogy in various disciplines and contexts around the
world and recognized as effective teaching-learning
method. Unlike many conventional methods it involves
students for effective learning through discussing and
finding solutions of authentic problems among themselves.
The students’ difficulties for communication in English
writing on the one hand, and PBL’s success stories on the
other made the researchers to venture for experimentation
with PBL and to see the effect of PBL on secondary level
students’ English writing skill.
1.1. Problem Based Learning as Pedagogy
Problem based learning has potential to arise curiosity
in the learners as Sonmez and Lee ([20], p. 1) were of the
view that “PBL is an instructional approach that
challenges learners to seek solutions to real world (open-
ended) problems by themselves or in groups,.. PBL
engages learners in developing skills as self-directed
learners.”
American Journal of Educational Research 1316
Many researchers has justified the used of problem
based leaning as pedagogy [1,14,22], curriculum [5] and
in many other forms according to the situation, domain
and goals of the programs [2,4]. In most popular terms it
has been used as pedagogical approach for learning where
the students are challenged with some simple and
unstructured problem [2,12,16], the simplicity and the
novelty of the problems help to engage students actively.
They are required to find the solution of that problem by
working in small groups of 4-5 each. Being a student-
centered approach, the teacher’s role is minimized to a
guide and facilitator only; the students perform all the
tasks. The class is divided in small groups of 4-5 each and
some authentic and worthwhile real life problem is
presented before the class that should be according to their
level and interests. The solution of the problem is sought
and found generally in three class meetings. The students
discuss and agree upon its nature, study and tools required
for solution in the first meeting and pursue it after the
class by studying the matter at home. The second meeting
ends after more discussion clarifying and narrowing down
their focus for finding the solutions of the problem and
need for more study, followed by more work at home and
writing down the possible solutions. The third meeting
aims for sharing of their solutions, discussing and
debating more for final agreement in the groups and
presenting the solution(s) before the whole class for
discussion, agreement for most appropriate solution and
writing it accordingly.
PBL was commenced in 1950s and 1960s in Canada, it
was thought, adapted and applied at Canada’s medical
schools for teaching subjects in Medicine and Natural
Science in 1970’s [16,17,18]. The case study teaching
technique was adopted at Hamilton, Ontario, and
McMaster University Medical Schools in Canada
followed by medical schools in USA and in many other
countries. Later on, PBL has been tried out in various
contexts, disciplines, and levels around the world and
found successful and effective; Gijbels et al [8] have
mentioned a fairly long list of disciplines and contexts
where PBL was applied and found effective. PBL has also
been applied in the context of secondary education
[9,10,,13,14] and experimented in the context of English
writing skill too [21] and the results and findings were
quite encouraging. Due to its importance and effectiveness
the researchers intended to apply PBL as pedagogy for the
teaching of English writing skill at secondary level. As
new pedagogical methods and techniques like problem
based learning have been found effective in various
contexts and situations and improved teaching-learning
significantly. These practices enhance students’ various
faculties in all domains; cognitive, psychomotor and
affective up-to maximum level of creation, thus adding
more to constructivism. The present study’s findings
would be significant to various stake holders in education
system like students, teachers, educational leaders,
curriculum designers, and policy makers, as these could be
extended to similar situations. The students would benefit
by following the same to improve their competency in
language skills and making the learning meaningful. The
teachers could apply PBL in their classroom teachings.
The educational leaders could adopt PBL for enhancing
teaching-learning environment at their institutions by
facilitating the teachers and students for PBL
implementation. The curriculum designers could include
PBL at various levels especially in teachers’ training
courses. The policy makers could decide to give more
weight-age to creative knowledge and constructivism in
assessment and evaluation systems, and to adopt PBL as
pedagogy in school education system across the country.
Moreover, this study would be a good addition in the
repository of research and knowledge regime.
1.2. Statement of the Problem
The present study was carried out at a public Secondary
school; Islamabad Model College for Boys G-7/4
Islamabad, Pakistan (IMCBIP). The purpose of the study
was to see the effect of problem based learning on
secondary level students’ English writing skill. The
secondary level students in Pakistan face difficulties in
their written expression while communicating in academic
and real life situations. The conventional lecture methods
depend more on teaching about the language emphasizing
on learning of grammatical rules of language rather than
the language itself. The problem takes its acute shape
when it is for learning of second or foreign language like
English. The teachers depend on text books for reading
comprehension, solving the exercises given at the end of
each chapter, and making the students memorize the
information and other aspects of the subjects for
reproducing these in the examinations. There is hardly any
effort to improve students’ free written expression except
rare endeavors by some teachers and researchers through
employing new pedagogical methods and techniques. The
situation demanded that some new pedagogy like PBL be
experimented to see whether it could be effective for
improving students’ English writing skill.
Like many other researchers, Dwi [7] has also found
PBL effective for teaching English writing skill. Keeping
in view these results and students’ difficulties, the
researchers decided to see the effect of PBL on secondary
level students’ writing skill at IMCBIP.
1.3. Objective and Hypotheses of the Study
The major objective of the study was to see the effect of
PBL on secondary level students’ writing skill through
measuring their achievement after learning through PBL
in comparison with that of the students who were taught
through conventional lecture method. The objective was
translated into the following hypotheses:
1. H
0
1: There is no significant difference between the
pretest and posttest mean scores of students taught
through problem based learning.
2. H
0
2: There is no significant difference between the
pretest and posttest mean scores of students taught
through conventional lecture method.
3. H
0
3: There is no significant difference between the
achievement scores in English writing skill of
secondary level learners using conventional lecture
method and Problem Based Learning.
2. Methodology
The study was experimental in nature with pretest-
posttest control group design, and carried out at Islamabad
Model College for Boys Sector G-7/4 Islamabad Pakistan
1317 American Journal of Educational Research
(IMCBIP) for four weeks’ experimentation of PBL for
teaching-learning of English essay writing to the
secondary level students during April-May 2014. English
essays were taught through making of lesson plans,
adopting PBL on Shoestring approach as suggested by
Savin-Baden and Major [19] and given below:
Figure 1. Problem-based Learning on a Shoestring (Adapted from Savin-Baden and Major [19])
This approach allows a flexible implementation of PBL
to the specific area of study; only the selected area is
taught through PBL, while other areas and topics are
taught though conventional lecture method simultaneously.
In this study only English essay writing was undertaken
through PBL; all the other topics were covered through
conventional method so that the students could be saved
from extra load and demand of work and any sense of
time loss.
The Morrison, Ross and Kemp Model (Classroom-
oriented) instructional design as suggested by Prestera
(2002 cited in the Herridge Group Inc [11]) was followed
because of its orientation that is taken from students’ point
of view (Student centered approach), its being a cyclic
system, and all the elements and steps are independent of
one another and one can start from anywhere one likes.
3. Participants/ Subjects
All the 156 students of 9
th
grade in IMCBIP were the
population for this study. 40 students were randomly
selected for this study, pretested and randomly divided
into experimental and control groups.
4. Instrumentation
Pretest and posttest were used for data collection which
were validated and went through reliability accordingly.
These tests are given below:
Pretest:
Question: Write an essay on any one of the topic/
statement in 170-200 words:
I. My Impressions of First Day in this New Class
II. How I spent my Latest (last) Holiday.
HINT: (Write all your activities on that day
from early morning till evening and
your expectations and feelings before
and after spending your first day in the
class/ last holiday)
Posttest:
Please read the given passage carefully:
“Heavy school bags have always been problem
for children and parents. Every day, you see little children
carrying heavy bags on their backs which are often
heavier than their own weight. In some cases parents serve
as porters to save their children from burden but in most
of the cases the students have to face the brunt. If you
examine the bag of class one student, you will find five to
eight books: English, Urdu, Mathematics, General
Knowledge, Rhymes, Islamiat, General Science, and
Drawing, same number of note books or work books.
Moreover there must be one pouch for pencils, erasers,
sharpener, color pencils, pair of scissors, glue stick etc.
Lunchbox and water bottle are also the need of the hour.
The students have to travel to and fro from school daily.
They surely feel the burden physically, and
psychologically which often hinder their growth. Is there
any way out that they can be facilitated by lessening this
burden?”
Keeping in view the above written problem, write
an essay of 170-200 words on the following:
“The Impact of Heavy School Bags on Students’
Growth: How this Load can be alleviated?”
Hint: Write the things you can find in a student’s bag
that make it heavier (All books, note books etc),
what are the effects on his physical, mental and
psychological/ emotional health, the difficulties
he faces, and the solutions for making the bag
lighter.
Marking Rubric:
The following rubric was used for evaluation of
students’ essays:
Figure 2. Rubrics for Marking of Essay
5. Analysis of Data
The data was analyzed through applying t-test and
descriptive statistics and the following results are found
and given in the following tables:

American Journal of Educational Research 1318
The pretest results in Table 1 above show that
difference of mean score for both the groups at level of
confidence α = 0.05 is zero showing that both the groups
are equivalent, the mean difference is not significant
(1.000 > 0.05) and confirms the null hypothesis that there
was no significant difference between the scores of both
the groups; null hypothesis was accepted implying that
both the groups were exactly equivalent at the start of
experimentation.
How much improvement occurred in the scores of
experimental group was analyzed using paired sample t-
test? The comparison is presented in Table 2 below.
Table 2. Comparison of Mean Scores of Experimental Group in Pretest and Posttest.

posttest 20 7.9450 1.95380
*Significant at α=0.05.
The results shown in Table 2 above reveal that
difference of mean for experimental group between pretest
and posttest score is significant (p=.014). This implies that
the learners achieved enough after treatment through PBL.
The descriptive analysis presented in Table 3 below
elaborates the point further:

The data analysis of Table 3 above reveals that the
mean difference of scores between pretest and posttest
(1.62) shows that the experimental group has shown
significant (p=.000) difference in their performance in the
posttest as compared with the pretest implying that
treatment given to this group (PBL pedagogy) has been
proved effective.
The results in Table 2 and Table 3 reveal that
experimental group made significant improvement as the
difference of mean of pretest and posttest scores were
significant; implying that null hypothesis H
0
1 was rejected
stating that there was no significant difference between the
pretest and posttest mean scores of students taught
through problem based learning. While alternate
hypothesis H
1
1 was accepted stating that there was
significant difference between the pretest and posttest
mean scores of students taught through problem based
learning. This showed that PBL was an effective
pedagogy for teaching English essay writing to secondary
level students.
To what extent the control group improved their scores,
is interesting to consider, the following Table 4 presents
the comparison of scores of control group.

The above given results in Table 4 show that control
group’s mean scores difference between pretest and
posttest is significant (.036 < .05) implying that the
learners in control group has also shown significant
improvement after learning through conventional lecture
method in the class. The descriptive data analysis
presented in Table 5 below shows control group’s
difference of mean score between pretest and posttest.

The data analysis in Table 5 above reveals that the
mean difference of scores between pretest and posttest
(.10) shows that the control group has shown significant
(.745) improvement in their performance in the posttest as
compared to the pretest implying that treatment given to
this group (Conventional lecture method) has also been
proved effective. The results from Table 4-Table 5 reject
the null hypothesis H
0
2 that there was no significant
difference between the pretest and posttest mean scores of
students taught through conventional lecture method, and
alternate hypothesis H
1
2 was accepted that there was
significant difference between the pretest and posttest
mean scores of students taught through conventional
lecture method.
The results of data analysis shown in Table 2 Table 5-
reveal that both the experimental and control groups made
significant improvement during the course of treatments
as indicated through the difference of mean scores
between their relevant pretest and posttest. It is not yet
clear which of the group made more progress and shown
more improvement in their learning and which one
method has proved more effective in this context. For this
purpose, comparisons of mean scores in posttest are
presented in the next tables.

The posttest results in Table 6 above show that mean
scores of experimental group (7.95) is greater than that of
control group (6.43). Similarly, from Table 3 & Table 5
the results show that the difference of mean scores of both
the groups in pretest and posttest (1.620-0.1000=1.52)
clarifies that achievement of experimental group in
posttest is greater than that of control group The
difference of mean scores was significant (p=0.006< 0.05)
at level of confidence α = 0.05, given in Table 6 and
e
nough evidence to reject the null hypothesis H
0
3 that
there was no significant difference between the mean
scores in English writing skill of secondary level learners
using conventional lecture methods and Problem Based
Learning. Hence the alternate hypoth
esis H
1
3 that there
was significant difference between the mean scores in
English writing skill of secondary level learners using
conventional lecture methods and PBL. This implies that
PBL was more effective pedagogy than conventional
lecture method for teaching English essay writing to
secondary level students and for improving their English
writing skill.
6. Findings and Recommendations
The results of the study showed that PBL was more
effective than conventional lecture method for teaching
English writing skill to the secondary level students. The
study is supported by the similar results found by
Sojisirikul and Siriyothin [21] leading to the conclusion
that PBL was more effective as pedagogy for teaching
English to undergraduates. Dods [6] found effectiveness
of PBL in promoting knowledge acquisition and retention
in the subject of biochemistry. Maxwell, Mergendoller,
and Bellisimo [14] found PBL effective for learning
Economics. Gijbels et al [8] made empirical and quasi-
experimental studies and concluded that generally the
effect of PBL remained different according to the levels of
the knowledge structure being measured. PBL had the
most positive effects when the focal constructs being
assessed were at the level of understanding the principles
that link concepts, the second level of knowledge structure.
It is recommended that PBL may be applied for
teaching English writing skill of secondary level students;
the teachers, educational leaders and policy makers may
arrange and facilitate for PBL’s implementation, and the
curriculum designers may include PBL as part of teachers’
training programs.

Abstract English has been recognized as important language in Pakistan like many other counties of the world
and used for academic, research, communication, business and official purposes. It has been taught as compulsory
subject up to graduation level. The students at all levels and especially secondary level try to have competency in

achievements. But they feel difficulty to acquire competency because of many reasons; the conventional teaching
method being used as one of the causes. New pedagogical methods like Problem Based Learning need to be
experimented in Pakistani situations as it has been proved a successful pedagogy in many contexts around the world
[8]. PBL as pedagogy is a teaching-learning method where students work in learner-centered classroom environment
in small groups of 4-5 confronting the authentic problems given by the teacher and find their solutions by discussing
among themselves generally in three class meetings. They work more at home by studying and searching for the
solutions. The present study was an attempt to experiment PBL learning of English writing skill through English
essay writing on secondary level students at IMCBIP (Islamabad Model College for Boys, Sector G-7/4 Islamabad,
Pakistan) and to see effectiveness of PBL in comparison of that of conventional lecture method. The study was
conducted by using pretest-posttest control group experimental design with the subjects (20+20 experimental &
control groups) and data were analyzed by employing t-test and descriptive statistics. The findings showed that PBL
was more effective pedagogy than conventional lecture method for improving English writing skill of secondary level students.
