In this study, improving senior secondary students’ retention in electrolysis using Collaborative Concept Mapping Instructional Strategy (CCMIS) was examined. A sample of 189 students from six selected secondary schools out of a population of 5,114 Senior Secondary I students from Ardo-Kola Local Government Area of Taraba State, Nigeria was used for the study. Non-equivalent quasi-experimental research design was adopted. The instrument used for data collection was Electrolysis Retention Test (ERT) with the reliability value of 0.78 using Kuder-Richardson. Two research questions and three null hypotheses guided the study. Mean and Standard Deviation scores were used to answer the research questions while Analysis of Covariance (ANCOVA) was used to test the null hypotheses. The study revealed that there is significant difference in the mean retention scores between students taught electrolysis using CCMIS and discussion method in favour of CCMIS; [F(1,97) =6.300, P<0.050]. No significant difference was found in the mean retention scores between male and female students taught electrolysis using CCMIS; [F(1,97) =6.300, P>0.050]. It also found no significant interaction effect between methods and gender on the mean retention scores of students in electrolysis; [F(1,197) =.318, P>0.050]. It was recommended among others that CCMIS should be adopted while teaching electrolysis since it has been proved to be a viable option in enhancing students’ retention capacity regardless of their gender.

The study examined effect of constructivist strategy on students Achievement in Senior Secondary Mathematics in Rivers State. The research was guided by three research questions and corresponding hypotheses. The population is all the thirty four thousand, one hundred and sixty eight (34,168) of all Senior secondary II (SS11) students in Rivers State during the 2018/2019 Academic year. A sample size of 280 students in four intact classes were selected through purposive sampling technique. Two of each of the classes were used as experimental and control groups. Non randomized pre-test, post test control group design was used for the study. Instrument used for the study was Mathematics Achievement Test (MAT) made up of 25 items drawn from simple statistics and Lesson Packages. The instrument was validated by experts and reliability coefficient of the instrument was obtained through test-retest method. The scores obtained were subjected to Pearson product moment correlation coefficient analysis and the result yielded 0.82. Analysis of Covariance (ANCOVA), Mean and Multiple Classification Analysis  (MCA) were used in analyzing the data. Findings reveals that constructivist strategy was more effective in facilitating students achievement in Mathematics than expository method. The result did not show a significant difference in students’ achievement in Mathematics in terms of gender and school type. The study therefore recommended among others the use of constructivist strategy in the teaching and learning of Mathematics in schools.

The study investigated the effect of hands-on activity-based method on interest of senior secondary chemistry students in organic chemistry. The study adopted a quasi-experimental design. A sample of 184 students from four purposively selected secondary schools out of a population of 2,381 SS II students from Makurdi Local Government Area of Benue State, Nigeria was used for the study. The experimental group was taught organic chemistry using hands-on activity-based method while the control group was taught using discussion method. Two research questions and two hypotheses guided the study. A validated 25-item Organic Chemistry Interest Inventory (OCII) was the instrument used to collect data. Reliability coefficients of 0.84 were established using Cronbach Alpha. Mean and Standard Deviation scores were used to answer the research questions while Analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. The results indicated that students taught using hands-on activity-based had significantly higher mean interest scores than those taught using discussion method (F=387.370, P(0.0001<0.05). Male and female students in hands-on activity-based group did not differ significantly in mean interest scores (F= 117.523, P(0.101>0.05). It was recommended that teachers should be encouraged to adopt hands-on activity-based method in teaching organic chemistry to enhance students’ interest in organic chemistry.

The study examined the effect of gender on students’ achievement in stoichiometry using hands-on activities. A sample of 292 students from eight purposively selected secondary schools out of a population of 8,381 SS II students from zone C of Benue State, Nigeria was used for the study. The study adopted a quasi-experimental research design. Stoichiometry Achievement Test (SAT) was used for data collection. Reliability coefficient of 0.92 was established using Pearson correlation moment coefficient. Two research questions and two hypotheses guided the study. The research questions were answered using mean and standard deviation while the hypotheses were tested at 0.05 level of significance using Analysis of covariance (ANCOVA). The study revealed that there is no significant difference in the mean achievement scores between male and female students taught stoichiometry using hands-on activities; (F(1, 145) = 4.160, p>0.05). It also found no significant interaction effect between methods and gender on the mean achievement scores of students in stoichiometry; (F(1, 291) = 0.11, p>0.05). It was recommended among others that since hands-on activities method is not gender sensitive therefore both male and female students should be involved in hands-on activities to enhance their achievement in stoichiometry.

This study focused on the Effect of Concept Mapping Teaching Strategy on students’ conceptual change in physics. Two research questions guided the study. Two null hypotheses were formulated and tested at the probability of 0.05 level of significance. The study adopted a quasi-experimental non-equivalent control group design. The study was carried out in Agbani Education zone of Enugu State. One hundred and nineteen students consisting of 63 boys and 56 girls from three co-educational schools were selected through purposive sampling for the study. Two intact streams of SSS 2 students in each of the secondary schools were used. The experimental group was taught concepts/principles involving refraction of the light wave using concept mapping while the control group was taught the same topics in optics using the conventional method. Thirty items on Test on Physics Concept (TPC) were developed by the researchers. The items were validated by three experts, one in measurement and evaluation and two in the Department of Science Education with a physics background, all from the Department of Science Education University of Nigeria Nsukka. Content validation was also carried out based on the table of specification. The reliability of the items was tested using the Kendall coefficient of concordance (W) with a coefficient of 0.81. Data on students' conceptual change in physics were collected using TPC. Pre-test scores were collected before the treatment while the post-test was administered after the treatment. Research questions were answered using mean and standard deviation while hypotheses were tested at 0.05 level of significance using analysis of covariance (ANCOVA). Results of data analyzed revealed that there exists a difference between the mean scores of physics students in Test of physics concepts when taught using concept mapping and lecture methods in favour of the group taught light waves using concept mapping strategy. That there exists no significant difference between the mean scores of male and female physics students in a test of physics concepts when taught using concept mapping and lecture methods. The recommendations among others are that concept mapping and lecture methods should be used interchangeably in the teaching of physics to breach the gap in performance between male and female students and concept mapping instructional strategy should be used to promote conceptual change in physics.

The study determined the relative effectiveness of enriched demonstration and lecture instructional strategies on senior secondary school students’ achievement in Chemistry. To achieve this, two research questions and three hypotheses were formulated to guide the study. Quasi-experimental design: specifically the pre-test, post-test, non-equivalent and non-randomized control group was adopted for the study. A total sample of one hundred and sixty-six (166) SS 1 students, drawn using multi-stage sampling technique were used for the study. The instrument used for data collection was Chemistry Achievement Test (CAT, r=0.82). Mean and standard deviation were used to answer the research questions, while analysis of covariance (ANCOVA) was used to test the hypotheses. Findings from the study revealed that: there is significant difference between the achievement of students exposed to two enriched instructional strategies and those exposed to enriched traditional lecture strategy; there is no significant difference between male and female students exposed to the three modes of instructional strategies; and there is no significant interaction effect between the instructional strategies and gender. It was recommended that chemistry educators should focus attention on reforming or enriching the traditional instructional strategies and that chemistry teachers should particularly make use of the enriched demonstration strategy in their classroom interactions, among others.
