(Lead City University, Ibadan, 2023-12) Olajoke Seye AJIBADE
The aim of this study was to assess the knowledge, attitude and preventive practices towards curtailing coronavirus infection among market traders in Ogbomoso North Local Government Area of Oyo State. In spite of many studies conducted on Coronavirus diseases among different groups, studies on the knowledge, attitude and preventive practices towards prevention of coronavirus among major market traders is not sufficient, nor has there been identified studies related to market traders in any of the Local governments in Ogbomoso. Thus, this theses attempted to fill this gap, engaging the theories of Knowledge, Attitude and Practices Model and Health Belief Model. Descriptive survey research design was used. Simple random, proportionate and convenience sampling techniques were used to select 300 respondents; while questionnaire was used for data collection. The descriptive statistics of frequency counts, percentages and inferential statistics of Pearson Product Moment Correlation were used for the analysis. The result of the study revealed that the level of knowledge of Coronavirus infection was high (mean=1.96), attitude was positive (mean=2.64), while preventive practice was high (mean=2.56) among market traders in Ogbomoso North LGA. Furthermore, there was no significant correlation between knowledge and attitude towards coronavirus infection (r=-0.026, p>0.05) among the respondents. There was no significant correlation between knowledge and preventive practices (r=0.061, p>0.05), while attitude had significant negative correlation with preventive practices of Coronavirus among the traders (r=-0.116, p<0.05). The authority of Ogbomoso North LGA in collaboration with State Ministry of Health should organise periodic Health Education programmes specifically on knowledge, attitude and preventive practices of coronavirus infection among market traders in Ogbomoso North Local Government Area.

(Lead City University, 2022-12) Kayode Sunday ADEYEMI
A close look at situations in universities in Nigeria suggests that majority of postgraduate students do not complete their programmes by the deadline, despite having completed the course work requirements for the programmes. Some even abandon their thesis and go on leave for reasons best known to them. This study did a comparative analysis of postgraduate students’ thesis supervision and mentoring in universities in Oyo State. The descriptive survey research design was adopted; population included all postgraduate students in public and private universities in Oyo State. A self developed instrument tagged ‘Postgraduate Thesis Supervision and Mentoring Questionnaire’ (PTSMQ) was developed to source data for the study. Data collected were analyzed with descriptive and inferential statistics. Results showed a high level of interpersonal contact between supervisors and supervisees at universities, high level of mentoring, Similarly, result found that there was a significant university type difference in mentoring of post graduate students with private university graduate mentoring (mean = 2.83, Std. = 0.938, p < 0.05) and public universities graduate students’ mentoring at (mean = 3.15, Std. =1.203, p < 0.05). The study equally found a significant university type difference in supervision of postgraduate students’ thesis in universities in Oyo State. Private universities (mean = 2.73, Std. = 0.856, p < 0.05) and public universities postgraduate students supervision at (mean = 3.07, Std. =1.196, p < 0.05).

(Lead City University, 2022-12) Adewole Olatunbosun OPATOLA
Issues of recidivism, and prisoners’ reintegration into the society have become sources of concern to critical stakeholders in criminology, psychology, and reformatory counselling. Corrections administrators have long recognized the possibility of education and proper reentry programmes as a method of creating a favorable change in incarcerated individuals. This feeling however, has been more of an intuitive notion rather than being empirically proven, particularly in Nigeria. This study, therefore, investigated correctional education and reentry programmes as predictors of prisoners’ desistance in the South-South, Nigeria. The study adopted the descriptive survey research design. Data collection was done using a questionnaire and key informant interview (KII). Data collected were analysed using the descriptive and inferential analyses at 0.05 level of significance. The results revealed that: there is a significant joint prediction of correctional education (literacy and vocational education) on prisoners’ desistance in South-South, Nigeria (F2, 286 = 42.603, Adj.R2=.224, p<0.05); there was a significant relative prediction of literacy (ß=0.301, t=4.796, p<0.05) and vocational education (ß=0.240, t=3.822, p<0.05) on prisoners’ desistance in South-South, Nigeria; there are practices of both formal and vocational correctional education as well as faith based and non-faith based reentry programmes in the Nigeria Corrections Service; there are evidences that correctional education and reentry programmes participation lower the likelihood of recidivism and increases the chances of cessation of crime amongst the ex-offenders. There should be establishment of responsive aftercare, rehabilitation and follow-up units for the ex-offenders, as these will go a long way towards solving the problem of recidivism, and increasing prisoners’ desistance, among others.

Swimming performance is a diverse activity combining energy, kinetic, motor control, anthropometrics, and swimming strength. When discussing the demands of speed and endurance, dry-land resistance training must be considered. The use of dry land training for swimmers has received little to no attention in several Nigerian researches. Therefore, this study interest was to examine the effects of a 6-week dry-land resistance training on swimming endurance and speed of swimmers in Lead City International School Ibadan. Pretest-posttest control group experimental research design using matched participants with a 2x2 factorial matrix was adopted for this study. Fifty-two swimmers of Lead City International School were selected to take part in the study. The participants were assigned into control group (26) and experimental group (26). Experimental group were made to go through six weeks dry-land resistance training programme, while the control group were made to undergo 20 minutes of benefits of exercise lesson for six weeks. Data were collected before and after the intervention programme. Data was analyzed using both descriptive and inferential statistics. The descriptive statistics used were frequency count and percentages, while Analysis of Co-variance (ANCOVA) was the inferential statistics used to determine the main as well as the interaction effects of the independent, dependent and moderating variables. There was a significant main effect of treatment on swimming endurance (F(1,49)=102.087, p<0.05, η 2=0.676) of swimmers in Lead City International School, Ibadan. There was also a significant main effect of treatment on swimming speed (F(1,49)=37.096, p<0.05, η 2=0.431) of Lead City International School swimmers, Ibadan. There was no significant main effect of sex on swimming endurance. Resistance training on dry-land improved swimmers' swimming abilities.

(Lead City University, Ibadan, 2024-12) Ameen MUHAMMED-RAJI
Senior Secondary School students in Nigeria often face significant challenges in mastering geometric concepts, resulting in poor academic achievement in Mathematics. This study aimed to determine the effects of Computer-Assisted Instruction (CAI) on students' academic achievement in geometry, as well as the moderating roles of students' motivation and attitudes. Given the importance of both instructional methods and student characteristics in educational outcomes, this research sought to provide insights into how CAI, combined with motivational factors, can enhance learning in geometry. A quasi- experimental research design was employed, involving a total of 150 students who were randomly assigned to CAI and control groups, which used traditional teaching methods. The students' academic achievement in geometry was assessed using the Geometric Achievement Test (GAT) (KR – 20=0.81), while their motivation and attitudes towards learning were measured using self-developed questionnaires. The Student Motivation Questionnaire (SMQ) (Cronbach alpha=0.73) and the Student Attitude Questionnaire (SAQ) (Cronbach alpha=0.76).Data analysis, using ANCOVA, revealed significant differences in academic achievement between the CAI group and the control group (F(1,145)=54.578, p<0.05), indicating that students exposed to CAI performed significantly better than those taught through conventional methods. Furthermore, the results showed that students' motivation (F(1,145)=5.582, p<0.05) and attitudes (F(1,145= 6.216, p<0.05) had a significant positive effect on their academic achievement in geometry. Additionally, motivation and attitudes were found to moderate the effectiveness of CAI in improving students' performance (F(1,134)=6.353, p<0.05).Based on these findings, the study recommends the integration of CAI into the geometry curriculum, along with targeted teacher training programme to maximise the benefits of technology in education. Furthermore, addressing and fostering positive student motivation and attitudes should be prioritised to further enhance the effectiveness of CAI. This research contributes to the growing body of evidence supporting the potential of CAI in improving learning outcomes in geometry and provides a foundation for future educational interventions.

Students’ achievements in Algebraic expressions concept as a course under Basic General Mathematics II for students in all Federal Colleges of Education, Nigeria over the years have not been encouraging. This may be due to factors like large class-size, crowded classrooms, misinterpretation of word problems, gender differences, students’ attitude and interest in the course, teaching methodologies employed by the lecturers and other factors. Many scholars had worked on class-wide peer tutoring but not many have worked on the combined effects of problem-solving strategy hence this study determined effects of class-wide peer tutoring and problem-solving strategy on Federal Colleges of Education students’ academic achievement in Algebraic expressions in Southwest, Nigeria. The population for the study comprised all the 100 level Students in Federal Colleges of Education Southwest, Nigeria. A random sampling technique was used to select 380 students for the study. Three research instruments were used: Algebraic Expressions Concept Students’ Academic Achievement Test (AECSAAT) (KR20= 0.87), Questionnaire on Students’ Attitude (QSA) (r=0.76) and Lesson Plan Format (LPF). Seven hypotheses were formulated and tested using Analysis of Covariance (ANCOVA) at 0.05 level of significance. The results showed that there was a significant main effect of class-wide peer tutoring, problem-solving and conventional strategy on students’ academic achievement in Algebraic expressions (F (2, 379) =352.161, partial, η2=0.653); there was a significant main effect of gender on students’ academic achievement in Algebraic expressions (F (1, 379) =0.002 partial, η 2=0.200); there was a significant main effect of class-size on students’ academic achievement in Algebraic expressions (F (2,379) =352.161 partial, η2=0.653); there was no significant interaction effect of class-wide peer tutoring, problem-solving, conventional strategies and gender on students’ academic achievement in Algebraic expressions (F (2,379) =352.161 partial, η2=0.002); there was no significant interaction effect of class-wide peer tutoring, problem-solving, conventional strategies and attitude on students’ academic achievement in Algebraic expressions(F(2, 379) = 0.563 partial, η2=0.003); there was no significant interaction effect of gender and attitude on students’ academic achievement in Algebraic expressions(F (1, 379) = 1.135 partial, η 2=0.003) and there was no significant interaction effect of class-wide peer tutoring, problem solving, conventional strategies, gender and attitude on students’ academic achievement in Algebraic expression(F (2, 379) = 1.433 partial, η 2=0.008). It was concluded that class-wide peer tutoring and problem-solving strategies improved students' academic achievement in Algebraic expressions concept. It was recommended among others that class-wide peer tutoring and problem-solving strategies should be adopted by teachers of Mathematics.

The results of pre-service teachers in Cell Biology over the years as observed by the researcher and literature have not been encouraging. This may be due to unfavourable teaching environments, ineffective teaching strategies, overcrowded classroom, and low- quality practical sessions in the laboratory. This study determined the effects of concept mapping strategy and cooperative learning strategy on academic achievement in Cell Biology in Southwest, Nigeria in order to address the problem low academic in Cell Biology among first-year Biology pre-service teachers. A quasi-experimental design was used. The sample consisted of 355 first-year Biology students from three Federal Colleges of Education in Southwest, Nigeria: Oyo, Osiele Abeokuta, and Iwo in Osun. Data were collected using Biology Achievement Test (BAT) (KR-20=0.75), the Instructional Guides for Cooperative and Concept Mapping Strategy. Data were analysed using Analysis of Covariance (ANCOVA) with seven hypotheses tested at 0.05 significance level. The results revealed: a significant main effect of Concept Mapping Strategy on the academic achievement of students in Cell Biology (F1, 237)=29.485, p<0.05); a significant main effect of cooperative learning on the academic achievement of students in Cell Biology (F1,235)=11.011, p<0.05); a significant main effect of gender on the academic achievement of students in Cell Biology (F1,352)=6.936, p<0.05); a significant interaction effect of gender and Concept Mapping Strategy on the academic achievement of students in Cell Biology F(1,235)=10.744, p<0.05); a significant interaction effect of gender and cooperative learning on the academic achievement of students in Cell Biology (F(1,235)=6.206, p<0.05); The study concluded that concept mapping strategy and cooperative learning strategies were effective strategies that significantly enhance Pre-service teachers’ academic achievement in Cell Biology in Southwest, Nigeria. This indicate that educational institutions ought to incorporate these strategies into their curricula to enhance comprehension of complex topics, while also taking into account gender dynamics in instructional design. These strategies could significantly improve educational practices in enhancing academic outcomes in Cell Biology. The interactive effects of these strategies with gender further emphasize the need for gender responsive instructional planning. It was recommended that educators should adopt concept mapping strategy and cooperative learning as complementary strategies to enhance academic achievement in Cell Biology. Curriculum planners and teacher trainers in Colleges of Education should integrate these methods into their instructional design.

Over the years, students struggle with Genetics topics in Biology due to their lack of interest, poor teaching methods and abstract nature of the topic. This study therefore determined the effects of digital learning platforms on senior secondary school students’ v vi academic achievement in Genetics. Three hypotheses were formulated and tested at 0.05 level of significance. A quasi-experimental design using pretest- posttest approach was applied. Multi-stage sampling procedure was adopted. Three public secondary schools in Ibadan North Local Government Area were purposively selected based on their year of establishment. A sample size of 104 participants which comprised 50 male and 54 female participated in the study. Intact classes of SS 2 students in all the three schools were involved in the study. Genetics in Biology Achievement Test (GBAT) (KR-20 = 0.79) and instructional guides were used for data collection. Analysis of Covariance (ANCOVA) was used for data analysis. There was a significant main effect of treatment on students’ academic achievement in Genetics [F(2;101)=7.6,p<0.05. There was a significant main effect of treatment on students’ Academic Achievement in genetics (F(2, 101) = 7.60; p<0.05, partial η2 = 0.14). The students in flipped-google with collaboration group had the highest adjusted post-achievement score (?ത =19.77), followed by those in flipped- google without collaboration (?ത =19.05) and control (?ത =17.21) groups. There was no significant main effect of gender on academic achievement of students in Genetics. There was no significant interaction effect of treatment and gender on academic achievement in Genetics. Based on the findings, it is concluded that the digital learning platforms (flipped- google classroom with/without collaboration) were effective to teach Genetics in Biology. It is then recommended that Biology teachers should adopt the digital learning platforms in teaching as a student centered approach so as to boost their academic achievement in Genetics.

The research investigated the effects of Guided Discovery and Activity-based instructional strategies on students’ academic achievement in Physical Chemistry in Senior Secondary Schools in Lagos West Senatorial District of Lagos State. The moderating effect of gender was also examined. Review has shown that learner-centered instructional strategies are necessary for the teaching of some concepts in science. Scarcity of such studies on students’ achievement in Physical Chemistry using guided discovery instructional strategy and activity-based instructional strategy has informed this present study. The study adopted the pretest-posttest, control group, quasi-experimental research design. The instruments used for data collection was Physical Chemistry Achievement Test (PCAT) (KR20=0.81), teachers instructional guide on guided discovery strategy, teachers instructional guide on activity- based strategy, teachers instructional on conventional strategy and evaluation sheet for assessing teachers performance on the use of instructional strategies. The population of this study was 15376 of senior secondary two Chemistry students in study area. A sample of 129 students comprising 69 male and 60 female drawn from three schools within three Local Government Areas (LGA) in the district selected using multi-stage sampling procedures. Three null hypotheses guided the study. The hypotheses were tested at p≤ 0.05 level of significance using Analysis of covariance. There was a significant main effect of the independent variables (guided discovery and activity-based strategies) on the dependent variable. (F= 41.139, p < 0.05). The study further revealed that gender is not significant (F (1,122) =0.364, p >0.05). Based on these findings, it was recommended that teachers should be discouraged from using teacher-centered instructional strategy in teaching Physical Chemistry, instead, learner-centered instructional strategies such as guided discovery and activity-based should be used.
