Entry and School-based Assessment Grades as Predictors of Senior School Certificate Examination Grades in Mathematics

The study investigated the extent to which students’ entry grades and scores from their school-based assessment grades (i.e., end of term and mock examination grades) can predict their senior school leaving certificate examination grades in core mathematics. The study employed the exploratory research design to investigate the predictive validity of students’ high school entry grades and their school-based assessment grades in determining their West African Senior School Certificate Examination (WASSCE) grades. The study involved 989 students in a high school in the Eastern Region of Ghana who took the WASSCE in 2017, 2018 and 2019. A correlation analysis of the data revealed a significant positive and moderate relationship between the core mathematics school-based assessment grades of the students and their senior school leaving certificate examination grades. Also, a multiple regression analysis of the validity of the school-based assessment scores in predicting the students’ senior school certificate examination (SSCE) grades revealed that 44.1% of the total variance in students’ performance in the SSCE are accounted for by three school-based assessment variables (entry grade, end of term scores and mock examination scores) when combined

Technology Use Among Ghanaian Junior High School Mathematics Teachers in the Ahafo – Ano South District

The study sought to investigate technology use among Ghanaian Junior High School mathematics teachers in the Ahafo-Ano South District of Ghana. Descriptive survey (cross-sectional survey) design with mixed quantitative and qualitative data was gathered for the study. The population of the study comprised of all JHS mathematics teachers in Ahafo-Ano South District, Ashanti region. A stratified sampling technique was used to select 60 JHS mathematics teachers from rural, peri-urban and urban schools in the district. The findings revealed that mathematics teachers technology use in teaching Mathematics at the Junior High School level in the district was low (2.048 ± .85388). These technologies were grouped into manipulatives, digital/computer-based and audio-visual technologies. The results established that most of the teachers used manipulates in teaching Mathematics (3.120 ± 1.063). On the contrary, the results also showed that digital/computer-based technologies such as virtual protractors, calculators, geometry pad, stepping stones 2.0 comprehensive mathematics and computer game programs such as Globaloria etc., were never used by mathematics teachers in the district (1.621 ± .840). Similarly, evidence from the study adds that audio-visual technologies including television, pie chart assignment to students based on TV program and other audio-visual devices were never in use by mathematics teachers in the district (1.416 ± .712)

Nutritional composition of five new Nigerian

Introduction. A study was carried out to investigate the proximate and mineral composition of plantain and banana fruits of new hybrids selected in Nigeria, compared with those of a local cultivar, Agbagba. Our aim was to assess their nutritional value and to enhance the adoption and utilization potential of these new selected hybrids. Materials and methods. Five new Musa hybrids developed at the IITA, Nigeria, were investigated. Proximate values of fat, carbohydrate and protein of the samples were determined and the energy content of each sample was calculated. Fruit mineral analysis was performed for each cultivar studied. The data were statistically analyzed. Results and discussion. All the new hybrids were higher than the local cultivar Agbagba in protein and crude fiber content. Conversely, Agbagba fruit had the highest level of carbohydrate. A significant difference was observed between the PITA 14 hybrid and the rest of the cultivars in total energy and fat content. Both the BITA 3 and PITA 26 hybrids contained the highest levels of ash. The PITA 17 hybrid contained the highest moisture. The PITA 14 and PITA 24 hybrids were different from all other cultivars in phosphorus and copper contents. The calcium concentration in the PITA 14 and PITA 17 hybrids differed regarding the rest of the cultivars assessed. Also, the levels of potassium and manganese found in all the hybrids were different from those obtained in Agbagba, while the latter differed from all the hybrids in magnesium and sodium levels. Conclusion. The new Musa hybrids assessed are superior to the Agbagba plantain in nutritional value, which could enhance the adoption and utilization potential of these new hybrids by the local population
