Design and development of computer aided learning software for individualized instruction of physics in some selected secondary schools in niger state, nigeria
This study investigated the effects of a researcher-designed computer-aided learning (CAL) software on physics achievement of senior secondary students in Niger State, Nigeria. Eighty students were assigned to experimental and control groups. The experimental group used the CAL software while the control used traditional teaching. Both groups took a pre-test and post-test. Analysis found that the experimental group scored significantly higher on the post-test, indicating CAL is more effective than traditional teaching. It also found no significant difference in scores between male and female students using CAL, showing it benefited both genders equally. The study concluded CAL can help address problems in physics education like poor teacher skills and lack of materials.

Improvisation: an alternative approach to solving the problem of ill-equipped...theijes
Effective teaching for quality science education can only be achieved through “learning by doing” (practical) in well-equipped laboratory. However, ill-equipped science laboratories have reached an alarming level thereby making learning by doing impossible. This paper takes a look at the concept and skills or techniques of improvising biology teaching equipment (instructional materials) in Agricultural science as a viable alternative and a panacea to ill-equipped laboratories in post-basic education in Nigeria. The paper concludes that ill-equipped laboratories is one of the myriad of problems currently facing the teaching and learning of Biology and Agricultural science in Nigerian Senior Secondary Schools that needs urgent attention from all stakeholders in science education as government alone cannot solve the problem.
The realitiesof climate change are gradually dawning on everyone including children. The need for a
disaster reduction education requires the use of mobile technologies to identify some of the impact of
climate change within an environment and create awareness on the dangers associated with climate
change. Since the pre-service teachers will teach the primary school pupils, it is aptthat the use of mobile
technologies should constitute part of their preparation while in training. This paper examined pre-service
teachers’ perception of using mobile technologies in teaching climate change in the primary school. One
hundred and fifty (150) pre-service teachers in two Colleges of Education in the erosion disaster zones of
Anambra and Imo States in the south eastern state of Nigeria were used for the study. Three research
questions guided the study. The study utilized a survey approach to collect and analyze the data. The
results from the study show that the pre-service teachers were confident that the use of mobile devices will
createsignificant climate change awareness.However, the pre-service teachers saw the need for using
mobile devices fin their preparation.Suggestions were made towards ensuring the integration of mobile
technology literacy in the pre-service teacher education curriculum.
Assessment of Chemistry Teachers Usage of National Commission for Colleges of...iosrjce
This study assessed the College chemistry teachers assessment of their usage of eleven pedagogical
methods in the National Commission for Colleges of Education (NCCE) Benchmark. The study also monitored
the influence of teachers qualification and gender on the usage of these methods. The study was carried out in
both Federal and State Colleges of Education in the five States in South-East zone of Nigeria. The sample for
the study comprises of all the sixty-one (61) chemistry teachers drawn from the seven colleges (state & federal)
in the five States. Three research questions and the three hypotheses guided this work. 55-item questionnaire
constructed by the researcher from the eleven pedagogical methods in the Benchmark was used as instrument
for data collection. This instrument was validated by experts in the field and reliability sought and after pilot
study and found to have 0.87 alpha value using Cronbach technique. Data collected were analyzed using means
and standard deviation for research questions and independent t-test for hypotheses at 0.05 level of confidence.
The result obtained showed that chemistry teachers adequately use only four methods, (demonstration,
experimental, discussion and lecture) during their classroom instructions. All other seven methods were not
adequately used. It was also discovered that teachers’ qualification and gender have no remarkable influence
on the usage of these methods. Recommendations for the usage of other methods were made.

Previous research shows that the integration of mobile phones in the classroom is challenging, but numerous studies have also demonstrated that wireless networks and mobile tools to support collaborative learning improve educational outcomes. This study aims to question the feasibility of replicating their research methodology in Taiwanese classrooms. For this purpose, two conventional classes of second year license degree in Applied Foreign Languages were the respondents. The students’ attitudes were observed and their participation was examined through an interview that revealed the perceptions of their learning experiences. The results of this study show that students, when allowed to use their cell phones according to their own needs in a collaborative learning, become more interested in their learning and can improve their English efficiency more than students in the conventional classroom. It is thus recommended that highly advanced technology be integrated with more flexibility to match students’ learning needs and motivations.

Qualitative Chemistry Education: The Role of the TeacherIOSR Journals
Abstract: This paper discussed the role of a chemistry teacher towards improving the quality of education in Nigeria. The decline in the quality of education has been attributed to many factors. Some of these factors are unqualified teachers, examination malpractice,, lack of practical skills, method of classroom instruction, to mention but a few. The role of a chemistry teacher among others is to change the method of classroom instruction from lecture method to innovative learning strategy such as cooperative learning and concept mapping, and to make use of improvised materials in the absence of standard equipments . It also examine the problems associated with the fall in quality of education. Finally it is recommended that Government should ensure that adequate funds are released to train science teachers, since teachers are the main determinant of quality in Education.

The research examined the effects of hands-on teaching strategy on senior
school learners’ performance waves in Ilorin, Nigeria. Senior secondary
school (SSS2) science students were sampled at intact classes using a
purposive sampling technique. Researcher-designed instructional packages
on waves and Physics achievement test on waves (PATW) were the
instruments employed. The gathered data were analysed with the use of
descriptive and inferential statistics. Percentage, mean and standard
deviation were employed in answering the research question. Meanwhile,
Analysis of Variance (ANOVA) was utilised in testing the hypotheses
formulated at a 0.05 alpha level. The study showed that students’
performance exposed to hands-on instructional strategy was very impressive,
while students’ performance exposed to traditional strategy was low, there
was a significant effect of hands-on instructional technique on the
performance of students in waves and no statistically significant
collaborative effect of hands-on instructional technique and students’ gender
on performance in waves. It was suggested that hands-on instructional
strategies should be integrated and used to make teaching and learning more
concrete and active based for both teachers and students.

Abstract
In this, paper, the effect of a researcher-designed Computer-Aided Learning software on
students’ physics achievement in senior secondary school in Niger State, Nigeria was
investigated. The pre-test-post-test experimental-control group research design was
employed. Stratified random sampling was used to select 80 students (40 males and 40
females) for each of the experimental and control groups. A 50-item achievement test, the
Physics Achievement Test (PAT), was administered to the students as pre-test and post-test.
Two hypotheses were postulated and tested at 0.05 level of significance. From the analysis
the following findings were reached: (i) There was a significant difference between the
achievement scores of physics students taught with the Computer-Aided Learning (CAL)
software and those taught without the CAL software on the post-test (t = 15.74, df = 39, p £
0.05). This shows that CAL is a better approach to embark upon by physics teachers for
meaningful learning than traditional lecture method. (ii) There was no significant difference
between the mean achievement scores of male and female physics students taught with the
Computer-Aided Learning software (t = 0.31, df = 19, p ³ 0.05). This shows that the CAL
software stimulated males and females alike. The implications of the findings for the use of
CAL software were discussed. Recommendations for the improvement of physics education in
Niger State and suggestions for further studies were made.

Introduction
One of the problems of teaching and learning is the method of imparting knowledge
to learners. According to Stone (1991), the major difficulty in sciences is the method by
which the subjects were customarily taught without regard to instructional materials. The
pedagogical approach in imparting knowledge to learners has become inadequate to their
needs. Bajah (1995) and Okeke (1986) found that science subjects has not been taught in
Nigerian schools the way that pupils would benefit most, as science instruction has mostly
been teacher-centred.
For the past two decades, science education has been facing a lot of difficulties which
include poor performance of students in science subjects (Adeyegbe, 1992). Physics, like
other science subjects, recorded poor students’ performance both in national and international
97
2. examination (Ali, 1983). Many factors contributed to the poor performance of students in
physics examination (Akale, 1986; Okebukola and Jegede, 1986; Offiah, 1987; and Ali,
1988). The factors include:
(i)
Inability of the physics teachers to put across the physics concepts to the students
(ii)
Lack of skills and competence required for teaching physics
(iii) Shortage of qualified physics teachers
(iv)
Lack of teaching materials and equipment
Physics as a subject is very important for the scientific and technological
advancement of any nation. Though its usefulness cuts across all fields of human endeavour,
the low enrolment of students in the subject at both secondary and post secondary levels has
been a source of concern to various people especially physics educators at various times
(Omosewo, 1999; Balogun, 1985; Otuka, 1983; Ogunneye, 1982; Orisaseyi, 1977; Ogunyemi
and Eboda, 1974).
Lack of active participation of students is one of the factors responsible for students’
poor performances in science subjects (Inyang, 1988; Bichi, 1988). This has also been
indicated in West African Examination Council (WAEC) results of secondary schools where
students’ performances are generally poor in physics, chemistry, biology and other sciencerelated subjects (WAEC, 2000). This pattern of poor performance in the sciences by students
is also observed in tertiary institutions (Olarinoye, 1987). Omosewo (1999:99), asserted that
“physics teachers were using the lecture method for teaching the subject
in the secondary schools. The direct impact of this method on learners is
that it often leads to lack of understanding and this might cause poor
performance and low enrolment of students in the subject. The low
enrolment in physics is a cog in the wheel of the scientific and technological
progress in this nation”.
Many of the students see science as too abstract to comprehend, thereby resorting to
memorization or rote method of learning. Many students have also changed from science
subjects to art and commercial subjects while some dropped out and some failed woefully at
the final examination. Meanwhile, various attempts have been made by government, school
proprietors and teachers to facilitate effective teaching and learning of these science courses
which are the rudiments of development of any nation. Textbooks have been constantly
reviewed and rewritten in simpler forms and instructional materials of various types had been
designed yet the problems persist.
Ogunleye (2000) found out that in the era of technological advancement, technology
has had minimum impact on education. This is because 80% of teachers in Nigeria are mostly
using the chalkboard and textbook method (traditional method) in teaching. Actually most
schools do not have modern equipment and materials. The few schools that have these
equipment are unable to use them effectively as a result of erratic electric power supply and
at times the inability of some teachers to operate some of these equipment. However, constant
use of the traditional method of teaching is a major factor contributing to poor academic
achievement of physics students.
One of the major problems faced by students is inability to remember what has been
learnt. This problem is often caused by too much theoretical expression by the teachers while
learners are passive listeners. Students memorize and regurgitate facts and concepts.
98
3. The above problems confronting the teaching and learning of physics can be handled
using Computer-Aided Learning (CAL). Computer Aided Learning is a learning process in
which a student interacts with and is guided by a computer through the course of study aimed
at achieving certain instructional goals (Eke, 1988). Computer has been used in developed
countries to tackle most of these problems it could be used to transform classroom instruction
into a series of rich memorable experiences and thus reduce boredom and forgetfulness.
Computer can be used to teach all school subjects including science. In recent years,
the use of computer in the process of teaching and learning has become widespread in
educational institutions with the development of microcomputer (Ezeliora, 1997). According
to Ezeliora (1997),
“Computer is useful in almost all spheres of life such as in hospitals for
keeping records of patients, drugs, staff and accounts, instruments for
diagnosis and treatment. It facilitates the banking system and quickens
banking services to clients. It is very useful in professional services such
as engineering, chartered firms and business. Thus computer is regarded
as an all-purpose machine”.
Abimbade (1996) reported that the use of computer: (i) increase the time of learners
devoted to learning, (ii) Enhance the speed of availability of data and information, (iii)
Provide immediate feed-back (iv) Assist less qualified teachers and (v) increase teachers
efficiency and effectiveness. Udousoro and Abimbade (1997) and Adeniyi (1997) pointed
out that students taught mathematics and physics with computer achieved higher cognitively
than those taught without computer.
The purpose of the study was to compare the effect of Computer-Aided Learning and
the traditional method of teaching (chalk-and-talk method) in teaching and learning physics
in senior secondary schools in Niger State, Nigeria.
Research Hypotheses
The following null hypotheses were formulated and tested at p £ 0.05 so as to obtain
answers to the research questions:
(i)
There is no significant difference between the mean achievement scores of physics
students taught with Computer-Aided Learning (CAL) software and those taught
without it.
(ii)
There is no significant difference between the mean achievement scores of male and
female physics students taught with the Computer-Aided Learning software.
Research Design
The research design was a pretest-posttest experimental control group design.
Sample and Sampling Technique
The population for this study was made up of all the senior secondary class one (SSI)
students in two Local Government Areas in Niger State. The sample subjects were drawn
from two co-educational and two single gender schools in Bosso and Shiroro Local
Government Areas of Niger State. The subjects from the co-educational schools were
99
4. selected by the use of stratified random sampling technique. This method was chosen so that
the gender variable could be appropriately represented.
Twenty (20) science students were randomly selected for the study from each of the
four schools. In all there were forty (40) males and forty (40) females. The students were
taught the same concept of physics using chalk-and-talk method and Computer-Aided
Learning software.
Research Instrument
The research instrument was made up of 50 items of the Physics Achievement Test
(PAT) which was used as pre-test and post-test to measure both the lower and higher
cognitive skills of the students in physics. The fifty questions were selected from eighty
questions initially prepared. To obtain the fifty questions, the initial eighty questions were
subjected to the processes of validation and item analysis to determine the discrimination and
facility indices. The questions were also subjected to pilot study and reliability test before
using them as a research instrument. The time allocated for the test was eighty minutes.
A stem followed by four (4) options lettered (A-E) out of which only “one” was
correct. Students were instructed to select only one option as answer for each item. All the
options were plausible answers to the item.
Development of Self–Instructional Computer-Based Package
The Computer-Aided Learning (CAL) software was developed by the researcher
using the lesson notes prepared for the traditional (chalk–and–talk) method. The program
was written in Visual FoxPro programming language. The topics treated were selected based
on senior secondary school syllabus. The topic selected was from first term scheme of work
and falls between the periods that research was carried out.
The development of courseware for this research material follows the systematic and
recursive approach of instructional development model put forth by Mervill and Goodman
(1972); Philips et al. (1987); and Dick and Carey (1996). However, five trials were made
before the packages become successful. It was then tested with some few selected secondary
schools in Minna, Niger State. These schools used for testing the package falls between the
population of the study but not part of the schools selected for research study. Some of the
complaints from these selected pupils about the package was later used for further
modification and finally perfected the package
Validity and Reliability of the Instruments
The Computer-Aided Learning (physics package lesson) and the physics achievement
test (PAT) items was pilot tested and found to satisfy face, content and construct validity by
three experts in educational technology, physics and computer science departments. Item
analysis of the instrument was also carried out to determine the facility and discrimination
indices after which the final items for the instrument were selected and the reliability
coefficient computed using the split-half approach and the Richard Kuderson formula 21
(KR–2). The value obtained for the reliability coefficient was 0.97 and this was considered to
be quite adequate for this study.

5. Method of Data Collection
The data for testing the hypotheses were collected from the pre-test and post-test
administered to the subjects used in the study. Each of the tests was marked and scored over
hundred percent. The experimental group were exposed to physics lesson using ComputerAided Learning software for the period of six weeks while the control group were taught the
same physics lesson with traditional (chalk-and-talk) method. The total number of lesson
within six weeks is eighteen periods lasted for forty minutes.
After the duration of six weeks of treatment for the experimental group and six week
of lecture method with control group, the post-test was administered to both groups at the
same duration in the usual paper per-pencil method.
Method of Data Analysis
The scores obtained by different groups were computed and used in testing the
hypothesis. This data were analysed using mean, standard deviation and the t–test statistical
analysis. The level of the significance adopted for the analysis was p ≤ 0.05. This level of
significance formed the basis for rejecting or not rejecting each of the hypotheses.
Results and Discussion
Two Research questions were raised in this study and two null hypotheses were
formulated and tested to provide answers to the research questions. Analysis of the pre-test
and post-test data collected by means of the physics achievement test (PAT) were used to
answer the research questions using the two null hypotheses as guide. Means, standard
deviations and the t-test were employed in analysing the pre-test and post-test data.
The level of significance adopted for the analysis is 0.05. This level of significance
formed the basis for rejecting or not rejecting a null hypothesis. The summary of the data
analyses and results is presented below.
Performance of Experimental and Control Groups on the Pre-test
A pre-test was administered to both the experimental and control groups. The test was
the 50-item multiple-choice physics objective test (PAT). The subjects were allowed forty
minutes to do the test. The test was given to determine the academic equivalence of the
experimental and control groups.
The mean scores of students in the experimental and control groups on the pre-test
were calculated and the t-test computed for the two means. Table 1 shows the means,
standard deviations and the result of the t-test analysis.

6. The result in Table 1 indicates that there is no significant difference at 0.05 level of
significance between the pre-test mean scores of the experimental and control groups (t =
0.24, df = 39, p = 0.81). This means that subjects in the experimental and control groups were
at the same entry level with regard to academic ability before the physics topics were
presented to them. Their mean scores were statistically the same.
Performance of the Experimental and Control Groups on the Post-test
Hypothesis 1: There is no significant difference between the mean scores of physics students
taught with Computer-Aided Learning (CAL) software and those taught without the use CAL
software.
To test this hypothesis the post-test means scores of the experimental and control
groups were computed and compared using the t-test statistic. The result is shown in Table 2.

The result (of the t-test analyses) in Table 2 shows that there was significant
difference between the post-test mean scores of the experimental and control groups at 0.05
level of significance (t = 15.74, df = 39, p = 0.001). Hypothesis I was therefore, rejected. This
means that there was a significant difference at 0.05 level of significance between the
performances of students taught with the CAL software and those taught without the
software. Students taught with the CAL software performed better than those who were
taught without it. Hence, the CAL software enhanced the learning of physics.
Performance of Male and Female Students in the Experimental Group on the Post-test
Hypothesis 2: There is no significant difference between the mean achievement scores of
male and female physics students taught with the Computer-Aided Learning software.
To test this hypothesis, the post-test mean scores of male and female students in the
experimental group were computed. The analysis was carried out using the t-test statistic and
the result shown in table 3.

7. From the result in Table 3, it can be seen that there was no significant difference
between the post-test mean scores of male and female physics students in the experimental
group at 0.05 level of significance (t = 0.31, df = 19, p = 0.757). Null hypothesis 2 was
therefore not rejected. The performances of the male and female physics students in the
experimental group were equally enhanced by the use of the computer physics software.
Hence the CAL physics software was gender friendly.
Discussion
Findings on Table 2 indicate that there was a significant difference in the physics
achievement of students taught with the Computer-Aided Learning software. Those students
taught with the computer software performed better in the physics achievement test compared
with those who were taught without the computer software. The result seem to agree with
earlier studies which concluded that students taught mathematics and physics with computer
achieved higher cognitively than those taught without computer (Udousoro and Abimbade,
1997; Adeniyi, 1997; Hassan, 1997; and Jonah, 1991). Computer can, therefore, be seen as a
tool for effective teaching and learning of science subjects. CAL is an effective tool and
efficient development of individual cognitive structure, psychomotor and affective abilities.
Findings on Table 3 indicate that there was no significant difference between the
performances of male and female students who were taught physics with the computer
software. The male and female students performed equally well. The result agrees with the
findings of Abdullahi (1981) and Fuller (1982) who found that gender did not influence
students’ performance in science generally.
Conclusion
From the findings of this research work, the following conclusions were drawn:
(i)
Instructional strategies that teachers employ in teaching science subjects at senior
secondary school level have significant effects on students’ achievement. The
findings of the present study showed that better performance in physics was achieved
through the use of CAL software.
(ii)
The male and female students were affected positively and equally by the use of CAL
software in teaching physics. This showed that the effect of CAL software is not
gender dependent.
Recommendations
From the findings of the present study, the following recommendations are made:
1.
The use of computer for teaching and learning in our schools should be encouraged.
Therefore, computer education should be made compulsory for teachers and students
in all levels of our educational systems.
2.
Curriculum planners should enforce/inculcate the use of computer in
teaching/learning into school curricula.
3.
Educators should continue to lay more emphasis and implement the concepts of
educational technology as a means of enhancing the quality of education.
4.
Federal Government should fully implement computer literacy policy formulated in
1988.

In–service training should be given to teachers on Educational Technology
particularly on the production and use of computerised instructional media so that
they can appropriate the use of modern instructional technology.
There is need for government and non-governmental organisations to organise
seminars, workshops, conferences as well as in-service training for teachers on
methodology of teaching so as to be able to compare and contrast effects of different
methods of teaching on students’ achievement.
Schools should be equipped with computers and Internet facilities and other necessary
instructional packages for teaching and learning.
Science teachers should learn how to prepare Computer-Aided Learning software.
Emphasis should be placed on making learning to be a learner-centred affair as well
as teaching for meaningful learning.
The role differentiation amongst boys and girls should continue to be avoided when
teaching science. Each gender deserves equity in exposure to educational experience.
Academic cooperation, though not to the point of replication or subjugation, should be
worked out by departments of Mathematics/Computer science, Physics/Computer
science and Educational Technology to develop adequate software for effective
science teaching and learning.
