The study investigated the effects of chemistry-based puzzles on senior secondary school chemistry students’ interest and gender in chemical periodicity. The design of the study was quasi-experimental; specifically the pre-test, post-test non-equivalent control group design was adopted. A sample of 129 students from a population of 4369 was used in the study. Students were classified into experimental and control groups: Students in the experimental groups were instructed with chemistry-based puzzles while students in the control groups were instructed with the demonstration method. An interest questionnaire called Chemical Periodicity Concepts Interest Inventories (CPCII), constructed by the researchers and validated by experts from three universities in Nigeria, was used in the study. Reliability coefficient of the instrument was calculated and found to be 0.79. Three research questions and three hypotheses were raised in the study. The research questions were answered using Mean and Standard Deviation while hypotheses were tested at 0.05 confidence level using Analysis of Covariance (ANCOVA). Findings showed that students in the experimental group who were taught with Puzzle-Based Strategy (PBS) had higher interest in the topic ‘chemical periodicity’ than those in the control group who were taught with the Demonstration Method (DEM). There was no significant difference in the interest of students by gender. Interaction effect of gender and treatments on interest was not significant. It was recommended that teachers should incorporate puzzle-based instructional strategies in their teaching as a variety to curb boredom in the classroom due to monotony of the conventional methods among others.

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.

The study investigated constructivist practices through guided discovery approach and the effect on students’ cognitive achievement in Nigerian senior secondary school Physics. The study adopted pretest-posttest control group design. A criterion sampling technique was used to select six schools out of nine schools that met the criteria. A total of 278 students took part in the study; this was made up of 141 male students and 137 female students in their respective intact classes. Physic Achievement Test (PAT) with the internal consistency of 0.77 using Kuder Richardson formula 21 was the instrument used in collecting data. The data were analysed using Analysis of Covariance (ANCOVA) and t-test. The results showed that guided discovery approaches was the most effective in facilitating students’ achievement in physics after being taught using a pictorial organizer. This was followed by demonstration while expository was found to be the least effective. Also, there exists no significant difference in the achievement of male and female physics students taught with guided discovery, demonstration and expository teaching approaches and corresponding exposure to a pictorial organizer. It is recommended that physics teachers should endeavour to use constructivist practices through guided discovery approach in order to engage students in problem solving activities, independent learning, critical thinking and understanding, and creative learning, rather than in rote learning and memorization.

The study determined gender effect in the efficacy of group investigation and jurisprudential inquiry instructional models in enhancing adolescent students’ interest and achievement in voter education related contents of senior secondary school Government curriculum. The study adopted quasi-experimental non-equivalent pre-test, post-test control group design. Sample for the study consisted of 165 SS II students drawn from senior secondary schools in Nsukka Local Government Area of Enugu state Nigeria. Multi-stage sampling technique was used to select the intact classes from each of the schools that were assigned to the two experimental groups. Data collected using Multiple Choice Government Achievement Test (MCGAT) and Government Interest Inventory (GII) were analyzed using mean and standard deviation for the research questions and ANCOVA for testing the hypothesis at P < 0.05 level of significance. The findings showed that both group investigation and jurisprudential inquiry models were effective in enhancing interest and achievement of male and female students in voter education related contents in senior secondary school Government curriculum. However, group investigation proved more efficacious. These findings were exhaustively discussed with recommendations on how to manage gender factor in using student-centred instructional models in enhancing students’ interest and achievement.
