INVESTIGATION OF THE POTENTIALS OF JANI AND MALUMFASHI CLAY FOR USE IN METALLURGICAL INDUSTRIES

Vol

Abstract: This research investigates the properties of Jani and Malumfashi clays to employ them for large-scale applications in metallurgical industries. The result of the physical properties showed that Jani and Malumfashi clay samples possessed a thermal shrinkage of 21cycle and 24cycle respectively indicating their ability to withstand abrupt temperature changes. Cold crushing strength for Jani is 247.13kg/cm2 while that of Malumfashi is 335.95kg/cm2. Linear shrinkage for Jani is 7.46%, and for Malumfashi is 8.8%. Apparent Porosity for Jani is 23.2% and For Malumfashi is 29.08%. Moreover, the result indicated that Jani clay has a Refractoriness of 1350oC and Malumfashi 1448oC respectively. The modulus of Rapture for Jani is 6.68 kg/cm2 and Malumfashi 8.6 kg/cm2. The orientation of the clay samples was examined using SEM analysis. The XRD analysis, the result showed that the Jani clay sample contains three crystalline phases which include Quartz(71.3)%, Orthoclase(16.8)% and, Kaolinite(11.9)% while Malumfashi contains four crystalline phases including Quartz (63)%, orthoclase (17)%, Kaolinite (8)% and Albite (12)%. The composition of chemical oxides present in the clay samples was studied using the XRF analyzer. The results showed the presence of SiO2, Al2O3, MgO, Fe2O3, and K2O as the major oxides present in both the clay samples while CaO, TiO, and MnO were present in trace amounts. These results conclude that Jani and Malumfashi clay can be applied in metallurgical industries. Improvement of the clay through use of suitable additives or blending, and beneficiation is recommended.

EFFECTS OF KOLB’S EXPERIENTIAL AND GARDNER’S MULTIPLE INTELLIGENCE LEARNING MODELS ON STUDENTS’ COGNITIVE ACHIEVEMENT IN ELECTRICAL INSTALLATION AND MAINTENANCE WORK

Vol

Abstract This study investigated the effects of Kolb’s experiential and Gardner’s multiple intelligence learning model on students’ cognitive achievement in electrical installation and maintenance work. Two research questions guided the study while three hypotheses formulated were tested at 0.05level of significance. The study adopted a quasi-experimental treatment group design and it was carried out in North West Nigeria. The population for the study was 1300 National Technical Certificate II (NTC II) students offering electrical installation and maintenance work in technical colleges in North-West, Nigeria. The simple random sampling technique was used to select 127 students consisting of 109 male and 18 female students assigned to two treatment groups using intact class. The instrument used for data collection was Electrical Installation and Maintenance work Cognitive Achievement Test (ECAT).The instrument was developed by the researchers. To ensure content validity, the instrument was subjected to face validation by five experts. The internal consistency of the instrument was determined by using Pearson moment correlation coefficient of reliability 0.84. The data collected was analyzed using mean to answer the two research questions while ANCOVA was used to test the three null hypotheses. The study found out, among others, that Gardner’s multiple intelligence learning model was more effective than Kolb’s experiential learning model in improving student’s cognitive achievement in electrical installation and maintenance work. There was no influence of gender on students’ cognitive achievement. However, gender had no significant influence on students’ cognitive achievement. The study found no significant interaction effect of methods and gender on students ‘cognitive achievement. The study recommended among others that NBTE should incorporate Gardner’s multiple intelligence learning model in the teaching/learning of electrical installation and maintenance work in technical colleges. In addition, workshops, seminars and conferences should be organized by federal ministry of education and states science and technical schools management board for teachers to enable them update their knowledge and skills on the use of Gardner’s multiple intelligence learning model for improving students’ cognitive achievement in electrical installation and maintenance work

EFFECT OF FLIPPED LEARNING ON NIGERIA CERTIFICATE IN EDUCATION (NCE) MATHEMATICS STUDENTS’ INTEREST AND ACHIEVEMENT IN TRIGONOMETRY IN KANO STATE, NIGERIA

Vol

Abstract This study sought to determine the effects of flipped learning strategy on NCE Mathematics students’ interest and achievement in trigonometry. The study employed a quasi-experimental 2 x 2 factorial research design. The sample of the study consisted of 60 students, who had a personal computer and Internet access at home. They were randomly assigned into an experimental group of 32 students (22 males, 10 female) and control group of 28 students (20 males, 8 female) The instruments used for data collection during the pre-test and post-test consisted of a trigonometry achievement test (TAT) and trigonometry interest scale (TIS). The TAT was validated by specialists in mathematics education and measurement and evaluation using table of specifications constructed for the multiple choice test items. The multiple choice test had average difficulty and discrimination indices of 0.43 and 0.55 respectively. The reliabilities of the multiple choice test items and trigonometry interest scale were established using the coefficient of internal consistency based on Cronbach Alpha ().The reliability coefficients for the TAT and TIS were 0.68 and 0.75 respectively. The data collected from the pre-test and post-test were subjected to statistical analysis using the Statistical Package for Social Sciences (SPSS). The research questions were answered using descriptive statistics while the hypotheses for the study were tested using t-test statistics and the Analysis of Covariance (ANCOVA) with pre-test scores as covariates at 0.05 level of significance. The findings from the study showed that: flipped learning strategy was more effective than the lecture method in improving students’ academic achievement and interest in trigonometry. The result also shows that there was no significant difference between the achievement of male and female students from the experimental group in trigonometry and that there was no significant interaction effects of treatment and gender on students’ achievement in trigonometry. It was recommended among others that Curriculum planners and educational policy makers should consider a review of the curriculum to incorporate flipped classroom strategy into the Nigeria Certificate in Education Mathematics Curriculum
