A pre-test post-test quasi-experimental design was employed. There were 75 PTs each in the experimental group and the control group. Van Hiele Geometry Test (VHGT) was administered to all PTs as both pre-test and post-test. PTs in the experimental group were taught two-dimensional geometry using VHPI while the control group was instructed by conventional instruction. Chi-square results showed that the PTs in both groups had increment in their post-VHGT as compared to the pre-VHGT. However, the PTs in the experimental group achieved better levels of geometric thinking as compared to those in the control group (χ2 = 58.949, p<0.05). Again, results from paired samples t-test indicated a significant difference in mean scores between control and experimental groups favouring PTs in the experimental group (t=30.776, p<0.05). The significant improvement in the performance of the experimental group having more PTs at level 3 and 4 than at level 0, 1 and 2 suggest that the VHPI served a useful pedagogical approach, impacted positively on PTs geometric thinking levels and has the potential of improving teaching and learning of geometry in schools than the conventional approach.

However, traditional cost accounting has been criticized for cost distortion and lack of relevance during the last 20 years. Notwithstanding the criticisms, some firms in Ghana are still using the traditional method of overhead allocation. The primary purpose of this descriptive study was to examine how the company applies traditional method to allocate production overhead cost into the cost of its finished product. The study did not find much difference between how the company adopts the practical capacity method of overhead allocation in terms of its concepts and application and what pertains in the existing literature on the phenomenon, except in some few aspects of its practice. It was also found that the company does not at all times meet the requirements of IFRS-IAS 2.

The study was a cross-sectional survey of 499 respondents using structured questionnaire personally administered. A usable 358 questionnaire were returned, representing 71.7% response rate and analysed using Structural Equation Modelling approach. The findings indicate that the proposed model has high goodness-of-fit for student’s use of computer. It also found that access to Internet, classroom based learning with Internet and non-classroom based learning with Internet could be influenced by students’ computer use. Theoretically, the study fills the dearth of conceptual models in understanding the critical determinants that influence students’ computer use in the high education level in developing country context. It provides important implications for educational management in higher education. This paper contributes to the body of knowledge in the area of computer application in education.

There is now a burgeoning literature that examines sustainable development in the context of minerals and mining, most of which is concerned with sustainability at global and national scales. What these numerous perspectives on sustainable mineral extraction, minerals and metals recycling, environmental management, and social performance, is how sustainable development applies to mining companies the and what steps a mine must take in order to improve the sustainability of operations. Since mining processes have the potential to impact a diverse group of environmental entities, and are of interest to a wide range of stakeholder groups, there is ample opportunity for the industry to operate more sustainably. Specifically, with improved planning, implementation of sound environmental management tools and cleaner technologies, extended social responsibility to stakeholder groups, the formation of training, a mine can improve performance in both the environmental and socioeconomic arenas, and thus contribute enormously to sustainable development at the mine level.
