The study investigated Educators' competence and utilization of social media in science teacher education. The study was carried out in Alvan Ikoku Federal College of Education, Owerri, Imo state. Based on the purpose of the study, 2 research questions guided the study. The population of the study consists of all the Educators in school of science of the Institution. Based on the size of the population of the educators in school of science, they were all used as sample for the study. The descriptive survey research design was adopted in carrying out the study. The instrument for data collection was a researcher made likert 4-point type questionnaire titled "Educators Competence and Utilization of Social Media (ECUSM)". The instrument had reliability coefficient of 0.83 determined using the Pearson's Product Moments Correlation Coefficient formula. The instrument was administered to the respondents on face-to-face basis by the researcher. The result of the study revealed that the educators were competent on the use of social media for personal purposes. Social media platforms were not utilized for academic purposes in the training of trainee teachers. Based on the result it was recommended that teacher educators should be trained on the utilization of social media in teacher training process through seminars, workshops and conferences.

The study investigated the impact of instructional scaffolding approach on secondary school students’ achievement in Mathematics. The study was carried out in Owerri Municipal Council of Imo State. The study was a quasi-experimental research type adopting the pre-test post test non equivalent control design in carrying out the study. A sample of 237 senior secondary school II (SS II) students consisting of 81 males and 156 females was used for the study. The instrument for data collection was a researcher made 30 items objective test questions titled “Mathematics Achievement Test (MAT)”. The instrument had reliability coefficient of 0.85 determined using Kuder Richardson 20 formula  (KR20). The experiment group was taught mathematics using instructional scaffolding approach while the control group was taught using traditional approach. The data generated was analyzed using mean and standard deviation to answer research questions while Analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. The result of the study revealed that instructional scaffolding is effective in enhancing secondary school students’ achievement in mathematics and minimized gender bias. Based on the result it was recommended that mathematics teachers at secondary school level should apply instructional scaffolding approach in teaching to enhance students’ achievement.

The study investigated the impact of Geogebra Software on students' achievement in geometry. The study was carried out in Owerri Municipal Council of Imo State. The study was a quasiexperimental research type adopting the pre-test post test non-equivalent control design. A sample of 114 senior secondary two (SS II) students was used for the study. The instrument for data collection was researchers made objective test with reliability coefficient of 0.80 determined using Kuder-Richardson (KR 20 ) formula. The experiment group was taught geometry using Geogebra software while the control group was taught using conventional approach. The data generated was analyzed using mean and standard deviation to answer research questions while the hypotheses were tested using ANCOVA statistical tool at 0.05 level of significance. The result of the study revealed that Geogebra software was effective in improving students' achievement in geometry irrespective of gender. Based on the result, it was recommended that Geogebra software should be introduced in secondary schools to enable teachers use them for teaching mathematics.

The study investigated the reduction of examination malpractice in public examinations through computer-based test (CBT) mode of examination. The population of the study consists of all senior secondary three (SS3) students of nine (9) government owned schools in Owerri Municipal Council who sat for 2016 UTME using CBT. The study adopted the descriptive survey research design. A sample of 320 students was selected for the study through stratified random sampling technique. A 15 item likert 4-points of questionnaire was used in data collection. It had reliability Coefficient of 0.70 determined using Pearson's Product Moment Correlation Coefficient. The data generated was analyzed using mean and standard deviation to answer research questions while the hypotheses were analyzed using chi-square and t-test statistical tools tested at 0.05 level of significance. The result of the study showed that CBT effectively reduced examination malpractice. Based on the results it was recommended that, government, NGOs and private organizations should join efforts with Joint Admission and Matriculation Board (JAMB) to build CBT centers across the country to enhance the boards carrying capacity.
