Aim: The study sought to investigate the mathematics teachers’ perceptions and perceived skills of ICT in the teaching and learning of mathematics in some selected junior and senior high schools in Ghana.

Study Design: This study used descriptive cross-sectional survey research design.

Methodology: The main instrument used for the study was questionnaire. The sample size for the study comprised both JHS and SHS mathematics teachers. In this study, cluster sampling and simple random techniques were used to select one hundred and twenty (120) teachers in junior and senior high schools in the keta municipality of the Volta region of which 76 were males and 29 were females. Out of the one hundred and twenty (120) teachers selected, one hundred and five (105) teachers presented back the questionnaire for analysis, 42 were J.H.S teachers and 63 were S.H.S teachers.

Results: The respondents agreed that using ICT in teaching and learning of mathematics is good, indicating positive perception among teachers. Again, the respondents showed that they possess some level of skills in using ICT in teaching and learning of mathematics.

Conclusions: Most mathematics teachers in the J.H.S and S.H.S have positive perception and skills to support the view that the integration of ICT in the teaching and learning of mathematics is useful and can improve teaching and learning in the mathematics classroom.

In this paper, we investigate the generalized Pell-Padovan sequences and we deal with, in detail, four special cases, namely, Pell-Padovan, Pell-Perrin, third order Fibonacci-Pell and third order Lucas-Pell sequences. We present Binet’s formulas, generating functions, Simson formulas and the summation formulas for these sequences. Moreover, we give some identities and matrices related with these sequences.

The study was a descriptive survey that investigated clamping down the activities of Senior Secondary Certificate Examination (SSCE) miracle centres for quality secondary education in Anambra state, Nigeria. Two research questions and two hypotheses guided the study. The population of the study comprised 2,850 students from 18 public secondary schools in Awka South Local Government Area, Anambra State, while 570 students representing 350 females and 220 males (20%) were drawn as the sample using simple random technique. The instrument for data collection was a 21 item questionnaire, validated by three experts, two from Educational Management and Policy department and one from Measurement and Evaluation Unit of Educational Foundations department, all in Faculty of Education Nnamdi Azikiwe University, Awka. Cronbach Alpha reliability test was used to determine the internal consistency of the instrument which yielded co-efficient value of 0.85. Data obtained were analyzed through mean and t-test statistic at 0.05 level of significance. The findings indicate that various types of SSCE miracle centres activities should be clamped down like shutting down of all miracle centres and enforcement of examination malpractice Act 33 of 1999 as sanction to defaulters. Gender and location do not differ significantly in SSCE miracle centre types of activities and methods of clamping down. Based on the findings, the study recommended inter alia that, miracle centres should be clamped down, and enforcement of Policy Act 33 of 1999 upheld to sanction defaulters.

General Systems Theory (GST), as well as Systems Theory (ST), are in the attention of scientists everywhere. Their research has highlighted both an approach to micro-systems and especially to macro-systems, in both cases these being the ends of the current world range seen from a purely scientific perspective. For the present study, an attempt was made to bring to the fore only a part of the entire international debate on the notion of system. Objective of the study experienced such a limitation with respect to the scope of dynamic systems. As such the paper goal was to familarise the reader with the diversity of concepts and develpment stages specific to the General Systems Theory and Systems Theory, in particular with the dynamic systems classification and analysis of associated models.

High strength, high hardness and very tough engineering material derived from geologically occurring minerals and processed into a tool that rubs or wears off by friction is regarded as an abrasive. Abrasives are produced in different forms and shapes and they afford good opportunities for precision scraping away or machining. In this empirical paper, effort is made in establishing a case for the production of abrasive tools that are formulated with silicon carbide and aluminium oxide as catalytic raw materials. These are locally found in the researchers’ locality a place that has many geological deposits of solid minerals. At each of Ozizza, Ndibe, Kpoghirikpo and Unwana beaches, eleven samples of sand were collected at random locations from the Cross River that is flowing through Ozizza down to Unwana for physical and geochemical investigation to determine its suitability for abrasive making. Sand at the four locations were subjected to physical and geochemical investigation. Generally, the sand was physically characterized by bright colours of white, brown and yellow. Some samples at some locations contained dark specks of organic matter. From the distribution, the sand is generally of medium grade size as shown by the Scanning Electron Microscopy (SEM). Geochemically by X-ray fluorescence (XRF) analysis, the oxide contents are: SiO₂ (91.73%), CaO (0.045%), Al₂O₃ (4.24%), Fe₂O₃ (1.36%), TiO₂ (0.21%), K₂O (0.86%). The silica content (91.73%) of the sand is well above the industrial specification of 80% for sanitary ware making and suitable for the silica brick industry, for road dressing mixed with special asphalt. The physical and geochemical property results indicate that the sand is a good material for direct use in abrasive (sand paper and sand blasting).making, glass making and in the building and construction industries.
