Ilorin Journal of Education, 13(2), December 1993 AN EXPERIMENTAL REVIEW OF THREE INSTRUCTIONAL APPROACHES FOR TEACHING HISTORY AT THE SECONDARY SCHOOL LEVEL BY Dr. (Mrs.) A. A. Jekayinfa ABSTRACT This study was an experimental review of three approaches to teaching history at the secondary school level. The target population was all the second year senior secondary school (S.S.2) students offering History in Nigeria. The sample was taken from three towns: two in Oyo State and the third in Osun State. Seventy eight students randomly selected from three equivalent schools were used. Three instructional methods were used in teaching history to the students. Each of the methods has its own peculiar technique and materials. One of the three methods was used as a control and the other two were used as experimental. Three hypotheses were tested. Results showed that the discussion method of teaching (student-teacher centred approach) achieve more than any of the other two methods of teaching i.e the personalized system of instruction (PSI) and the lecture method. The result revealed that for effective teaching and learning of history, methods of teaching should be diversified and different instructional materials used as so as to enable learners to be critically minded, develop respect for evidence, be willing to change opinion and be able to develop divergent thinking. Ilorin Journal of Education, 13(2), December 1993 INTRODUCTION This study was based on the theory of some great philosophers like Rousseau and Dewey who belonged to the philosophical schools of Naturalism and Pragmatism respectively. They believed that education should not be regarded as simply a process by which the child receives approved knowledge from the teacher and the textbooks in a passive manner but, that education should be an active process which should be an interaction between the teacher, the subject and the child, within a healthy environment and that learning should be child-centred. (Adrian and Robert, 1973). In their book – Teaching Practice: A guide for Student Teachers, Adesina, Daramola and Talabi (1989) also discussed about the social interaction model which emphasizes the need for social relationship as a means of improving teaching. The model is an attempt to improve the democratic environment in the classroom and it intends to clarify the fact that the role of the teacher is supportive rather than dominating and it requires the teacher to allow students to take active part in the lesson through discussion based on their knowledge or ideas. BRIEF REVIEW OF THE LITERATURE Several researches have been carried out on the popularity of different methods of teaching. Ayot and Patel (1967) wrote that despite that the lecture method does not cater for realizing the aims of teaching almost all subjects, and it is not helping the learner to understand all that needs to be understood, it is almost dominant today and it is liked by the majority of teachers. For example, Adejumobi (1978) carried out a study of High School History Teaching. Eighty one (81) secondary school history teachers were asked 2 Ilorin Journal of Education, 13(2), December 1993 to indicate the frequency at which they use each of the six suggested methods of history teaching: The lecture method, the question and answer method, the text-book method, the patch or centres of interest method, the group method, and the notes methods. The lecture method was often used by 74% of the respondents. Similarly, Adeyinka (1983) carried out an investigation in Oyo, Ondo and Ogun States of Nigeria. Thirty six (36) fifth-form history teachers were requested to indicate the frequency of use of ten methods of teaching history. The rating scale was 5 for “Always”, 4 for “often”, 3 for “sometimes” 2 for “Rarely” and 1 for “Never”. The method investigated were the lecture methods, story telling, note giving, discussion method, socractic method, Dalton plan, project method, textbook method, dramatization method and excursion method. The result confirmed that the lecture method was most frequently used for teaching history in the secondary schools in the three states. It had a mean score of 4, out of a maximum possible score of 5, with as many as 33 (97.7%) indicating that they use the method always and 3 (8.3%) often. Linsday (1974) compared the effects of three methods of teaching high school Chemistry upon achievement. The three methods compared were a student centred, teacher-centred and CHEM study approach to high school chemistry. CHEM study is a structural chemistry curriculum material which stressed the inquiry process. He found that those in the student centred approach achieved more and has more scientific interest than students in other approaches. Shaw (1982) did a comparative study of the effects of two instructional modes in the achievement levels of selected fourth grade students. He compared the effectiveness of a whole class instruction and individualized instruction in a regular classroom setting on selected fourth grade students achievement levels. The 3 Ilorin Journal of Education, 13(2), December 1993 study was conducted in ten (10) elementary schools of a metropolitan school district. The findings of the result indicated that there was a significant difference between the achievement levels of the two groups. The whole class mode of instruction (lecture) was superior to the individualized mode. The objectives of this study were as follows: 1. To find out if there would be any difference in the performance of students taught using three different instructional approaches in a History Achievement Test. 2. To make suggestions and recommendations. Hypotheses In pursuance of these objectives, it was hypothesized that: 1. There is no statistically significant difference in the post-test mean scores of students (male and female) in the control group and the students in the experimental groups in the history Achievement Test (HAT). 2. There is no statistically significant difference in the post-test mean scores of male students in the control group and the students in the experimental groups in the history Achievement Test. 3. There is no statistically significant difference in the post-test mean scores of female students in the control group and the students in the experimental groups in the history Achievement Test. 4 Ilorin Journal of Education, 13(2), December 1993 METHODOLOGY Sample: subjects were seventy eight (78) SS 2 history students in co-educational institutions. The three institutions, one in Osun State and the other two in Oyo State of Nigeria were fairly homogenous in the sense that their students did the same pre-test and were also equivalent in their scores on the test. Research Design A quasi-experimental pre-test, post-test, control group design was adopted in this study. The design made use of non-randomised, equivalent groups which were assigned to treatment conditions (that is to different teaching methods) as explained below: O1 X1 O2 - Group 1) ) O3 X2 O5 O6 O1 O3 O2 O4 O4 Experimental - Group 2) - Group 3 – Control. O5 - Mean pre-test measurement O6 - Mean post-test measurement Where X1 – Experimental group 1 was exposed to the child centred approach to teaching (Personalised System of Instruction). 5 Ilorin Journal of Education, 13(2), December 1993 X2 – Experimental group 2 was exposed to the mid-way approach to teaching (Discussion Method of Instruction). The third group was the control group which was exposed to the teacher-centred approach to teaching (Lecture Method). Training of Teachers Teaching, which was financed by researcher, was done by three practicing history teachers. Each of the three teachers was taken from each of the three schools where the experiment took place. Each of the teachers had at least NCE with a minimum of 5 years of teaching experience. Prior to instruction, the researcher discussed details of each treatment with the teachers. They were subjected to two hours of training intended to equip them with the necessary skills for preparing for historical activities on the British Administration in Nigeria from 1900 – 1960. The teachers were trained in their various schools. The training took 2 days of 1 hour a day in each school. Instruments Two instruments were used in this study and they are 1. The Experimental treatment (instrument used for teaching); 2. The Evaluation Instrument (instrument used for testing). Experimental Treatment The content of the experimental treatment was obtained from the senior secondary school history syllabus. It was specifically taken from the aspect of British 6 Ilorin Journal of Education, 13(2), December 1993 Administration in Nigeria from 1900 – 1960. This aspect was chosen because it falls within the second year scheme of work and since the SS 2 students were used for the study, the materials, it was thought, will benefit the students. The content was broken into four learning units, each unit was also broken into two topics to be covered in one week of teaching. Thus, the four units of eight topics took four weeks of teaching. Evaluation Instrument This instrument was researcher-made. It was known in this study as History Achievement Test (HAT). The instrument had three sections – A, B and C. Section A consists of forty-five (45) multiple choice objective questions that covered the cognitive aspect of learning on the British system of Administration from 1900 to 1960. Section B consists of five open-ended questions that reflect the affective domain of learning which required the students to express their opinions on certain aspects of the topics while section C consists of five questions that demanded thirty correct responses in all on the psycho-motor domain of learning which required the students either to draw, locate or fix in some facts in the correct places. The instrument was used for both the pre-test and the post-test. The test was answered for two hours (2 hours) in each testing period. Validation of the Instrument The validity of the experimental treatment and the evaluation instrument was done using the following measures: 7 Ilorin Journal of Education, 13(2), December 1993 1. The instruments were given to some experienced history teachers in some secondary schools in Oyo State who attested to their contents and confirmed that they were in line with the approved syllabus for senior secondary II students. 2. Some lecturers I and Senior Lecturers in the Faculty of Education, University of Ilorin, also examined the instruments and attested to it that the language of the instruments is suitable for senior secondary II (SS II) students. The content validity of the evaluation instrument (HAT) was also confirmed by a pilot study conducted in two secondary schools, one in Ogbomoso Local Government and the other in Ibadan Municipal Government Area of Oyo State. A sample of fifty (50) SS 2 history students was used for the pilot study. The two schools which did the pilot study did not take part in the experiment. Initially, sixty (60) multiple choice questions were drawn to cover the cognitive aspect of the lesson to be taught for the four weeks of the experiment. In the analysis that was done on the test, item total correlation ranged from, 38 to .73. Fifteen (15) items whose correlations with the total scores in the test were less than .40 were removed, leaving the final objective questions with forty-five (45). The five affective and the five psycho-motor questions were left intact for they were found to be valid. Scoring of HAT The forty-five (45) objective questions that tested the cognitive aspect of learning were scored one point for each correct response, making 45 points. The five open-ended questions were marked by two history teachers in Ogbomoso and the researcher found 8 Ilorin Journal of Education, 13(2), December 1993 the average for each student. Each question was scored out of five marks making 25 points. The five questions that tested the psychomotor skills of the students had 30 correct responses both on location, arrangement of facts and drawings. Each correct response was scored 1 point, making 30 points. Thus, the History Achievement Test (HAT) was scored over 100. Procedure for Collecting Data At different times, the researcher administered the pre-test on the first day of visit to the students in schools where the experiment took place. The scripts were graded and the mean scores for the three schools were calculated. Experiment commenced a week after the pre-test. The experiment took a period of four weeks. Three lessons were taught per week. A lesson was taught for a duration of 40 minutes. Each class had History lessons of 5 hours, 20 minutes for the period of four weeks. The Post Test The History Achievement Test (HAT) had been administered on the subjects as the pre-test; so, it served as the criterion examination. The test was re-administered on the subject as the post-test. The researcher personally conducted all tests assisted by the History teachers in each school. The time allowed for the administration of the test was two hours. On the whole, a total of six weeks was given to the experiment. One week was given to the administration of the pre-test and random assignment of groups to treatment 9 Ilorin Journal of Education, 13(2), December 1993 conditions. Four weeks was given to the experiment (teaching) while one week was given for the administration of the post-test. Data Analysis Techniques Out of the 120 students that originally started the experiment, only 106 of them, made up of 56 boys and 40 girls, completed the six weeks. Those 14 students that absconded during the treatment either lost interest in the exercise or were affected by non-payment of school fees which made the school authorities to drive them out of the schools. Out of the 106 students who completed the exercise, the scores of 78 were finally randomly selected for analysis. This means that 26 students were used per school. The sexes were used in equal proportions for all the three schools. One way analysis of variance was used to test group equivalence of students on the Pre-test means. Analysis of covariance, using pre-test scores as covariates, and Turkey’s Studentized Ranged (HSD) were used to test the three hypotheses. RESULTS Presented in tables 1 and 2 are the analysis of co-variance of Post-Test scores of history Achievement Test (HAT) using Pre-Test scores as covariates and the Turkey’s (HSD) comparison Test between group means in (HAT). This is to test Hypothesis 1. 10 Ilorin Journal of Education, 13(2), December 1993 Table 1: Analysis of Covariance of Post Test Scores of History Achievement Test (HAT) by Methods of Instruction Scores of Covariates Df Sum of Mean Squares Square F.Value Significance of F Pre-Test 1 1026.126 1026.126 21.89 0.0001 Method 2 988.526 554.577 11.82 0.005 Explained 3 2014.652 335.775 7.16 0.0001 Residual 74 3328.643 46.882 Total 77 5343.295 Results in table 1 confirmed the existence of significant differences in the post-test scores accounted for by differences in the effectiveness of the instructional methods. In order to determine the direction of superiority of the instructional methods, Turkey’s Studentized Range (HSD) Post-Hoc comparison test was employed. Table 2 shows the summaries of the Turkey’s Studentised Range (HSD) comparison test between group means Table 2: Turkey’s (HSD) Comparison Test Between Group Means in History Achievement Test (HAT) Group N Turkey’s Group/Means Mean Control 26 58.73 B E1 26 62.73 A E2 26 64.73 A * Means with the same letter are not significantly different at 0.05 alpha level. In testing the hypothesis that stated that there will be no statistically significant differences between the post test mean scores of male students in the control group and 11 Ilorin Journal of Education, 13(2), December 1993 those of the experimental groups in the History Achievement Test (HAT), analysis of covariance, using pre-test scores as covariates, and Turkey’s (HSD) procedure were used. The results set out in table 3 showed the effects of treatment on students academic achievement as measured by the History Achievement Test (HAT). The explain variance, which is the combination of both the covariates and the methods, was found significant with an F-value of 5.28 at 0.0004 alpha level and at 38 degree of freedom. The methods of instruction alone was not significant at 0.05 level. It has an F-value of 1.08. This implies that discussion method (Teacher/student centred approach) did not differ significantly from the other groups in improving male students’ achievement in History. This is also reflected in the comparison test (Table 4).

To test the hypothesis of no significant difference in the mean scores of female students in the three groups, tables 5 and 6 were used to present the analysis of data collected on females’ scores.

The third hypothesis stated that there will be no statistically significant difference between the post-test means scores of female students in the control group and those of the experimental groups in Test of History Achievement. This hypothesis was also tested by the use of analysis of covariance using the pretest scores as a covariate. To determine the effects of quality of instructions on the posttests, Turkey’s Studentized Range (HSD) Test was employed. Table 5 showed that with a statistically controlled covariate effect, methods of instruction had significant effect on the post-test score with an F-value of 8.80 at 0.0001 alpha level. Results from the comparison table (table 6) showed that the teacher/student centred approach by the use of discussion method was more effective in producing improvement in female students’ academic achievement than either the teacher-centred approach (lecture method) or the student-centred approach (personalized system of instruction). DISCUSSION AND RECOMMENDATION As revealed by the present study, the discussion method (teacher/student centred approach) and the personalized system of instruction (Student centred approach) were more effective than the conventional lecture method (teacher centred approach) in teaching combined male and female students. This is in agreement with the results of some earlier studies such as Linsday (1974) and Shaw (1982). Such studies compared the effectiveness of individualized instruction and lecture methods and came out with similar report that PSI was more effective than the lecture method in the teaching of 14 Ilorin Journal of Education, 13(2), December 1993 subjects like Introductory Psychology and Chemistry. On the other hand, the finding of superiority of personalized system of instruction over the traditional method disagreed with Collard (1987), who came out with a report that there was no significant difference between the PSI and the lecture method for the students did equally well in either method of instructions and that both the traditional lecture method and the personalized system of instruction (PSI) did equally well as teaching methods regardless of sex and age. Result from this research showed that for male students, there was no significant difference in the post-test mean scores, between the control and the experimental group. There was also no superiority of any method over the other. This supports the inconclusiveness of the earlier studies on methods of teaching as found out by Gage (1968) when he claimed that: Although methods of instruction in colleges have been extensively studied for the past half century, the findings have been ambiguous or inconclusive. Taken as a whole, the available research evidence suggests that there is no demonstrable superiority of any given method. The result of this study for the female students showed that the two experimental methods, i.e. the discussion method and the personalised system of instruction are equally good for the teaching of History to the female students. However, the discussion method was more effective as shown from the mean scores of the two groups. The major findings of this study call for more commitment on the part of History teachers. It gives support to the use of discussion method (Child-teacher centred approach) in the teaching of History in co-educational institutions. Discussion method of instruction is possible if teachers can show more concern for the students. It involves the History teachers having contacts with the students in the classrooms. An encouragement 15 Ilorin Journal of Education, 13(2), December 1993 of discussion method leads the learners to critical mindedness, intellectual honesty, objectivity and willingness to change opinion, open mindedness and questioning attitude. All these affective process are important and teachers should encourage their developments in the students in the History class. According to Callahan and Clark (1977), in any classroom, there is constant action and interaction going on between teachers and students themselves. Discussion method should be introduced in the teaching of History to bring about meaningfully action and interaction in the classroom. 16 Ilorin Journal of Education, 13(2), December 1993 REFERENCES Adetunmobi, S.A.
