A mixed method approach was adopted for collecting data from a sample of 135 teachers who were drawn using random sampling technique, from 17 universities in Nigeria. A 30-item Big Data Assessment for Learning Scale (B_DALS) was used for collecting quantitative data, while a semi-structured interview schedule was used to collect qualitative data from a sample of 10 deans of faculties and heads of departments, who were not part of the sample of teachers. Quantitative data collected was analysed using percentage, mean and standard deviation descriptive statistical techniques, while themes in the qualitative data were identified and used to corroborate the quantitative data. The findings of the study reveal that less than 50% of the teachers were able to identify different sources of big data ...

The findings showed that the intervention administered to the experimental group was effective in reducing the students’ Mathematics test anxiety, changing negative attitude towards Mathematics and improving their achievement in the subject. It was concluded that persuasive communication, which hitherto was not available for use in the schools, proved to be a more effective intervention for reducing Mathematics test anxiety, changing negative attitude towards Mathematics and improving students’ Mathematics achievement than the intervention programmes conducted in the schools.

It also determined association of the students’ mastery level with school type and location. A diagnostic assessment was conducted and data was analyzed using Q-matrix and diagnostic classification model (Posterior marginal probabilities for skills of a threshold of 0.5), frequency counts, percentages and Chi-square. Findings of the study revealed that students have low mastery of all the automobile electrical works skills and that their mastery level is associated with the location and type of school they attend. This study provided empirical evidence on students’ learning difficulties in automobile electrical works that will help teachers in carrying out effective remedial instructions for students who are having learning difficulties, so that no child is left behind in the teaching and learning of th...

The study adopted a descriptive survey design. The sample was 269 lecturers. The researchers adapted the teacher sense of efficacy scale (TSES) developed by Tschannen-Moran and Hoy (2001) for the study. The TSES has two parts (1) and (2) that contained 12 questions each. It was a validated instrument, with overall reliability indices of 0.92 and 0.95 respectively determined using Cronbach’s Alpha. The data obtained were analyzed with mean, standard deviation, and paired sample t-test. The study found that the PDP improved the lecturers' understanding of modern technologies and self-efficacy in teaching (t (268) = 30.959, p ...

A non-equivalent, control group quasi-experimental design was used to investigate male and female undergraduates' achievement in science education. Data were collected from 85 second-year science education undergraduates and analyzed using mean, standard deviation, and analysis of covariance. The results show that POGIL pedagogy, as opposed to lecture pedagogy, resulted in improved academic achievement in science education (F (1,82) = 26.66, P = .000, ˂ .05). The data provided evidence to suggest that undergraduates that learned by the POGIL method had a greater grasp of content knowledge than their counterpart that learned by the lecture approach, as evidenced by higher mean achievement scores for POGIL undergraduates. There was no sig...

The oil was extracted with petroleum ether solvent and characterized with Association of Analytical Chemist (AOAC). The catalysts were synthesized by thermal, acid and alkaline activation of clay. The catalysts were characterized and used to transesterify the APO. The biodiesel produced were characterized using American Society for Testing Materials ASTM D6571 and some the thermo-physical properties such as density, kinematic viscosity and cetane number were modelled using multilinear regression analysis of Polymath version 5.0. The 52% yield of oil from the African pear seeds using the petroleum ether was comparable with yields obtained from other nonedible seeds. The transesterification of the oil was significantly affected by increase in process variables but the yield of methyl ester decreased beyond 3 h reaction time, 3 wt% catalyst conce...
