In schools, there is an additional emphasis on the role of evaluations in providing detailed, constructive feedback to all teachers, including those that are considered generally effective already, with data that can inform continuous improvement in practice.
It is now commonly understood that teacher effectiveness is the single most important school-level factor affecting student achievement – with principal effectiveness a close second.
While BIM processes are established for new buildings, the majority of existing buildings is not maintained, refurbished or deconstructed with BIM yet.
Promising benefits of efficient resource management motivate research to overcome uncertainties of building condition and deficient documentation prevalent in existing buildings.
This can be particularly useful in ensuring memory safety, i.e.
See the terminology section below for information regarding inconsistent use of the terms assembly and assembler.
Atomic Absorption Spectrometer(AAS) was used to determine the chemical composition, while other established processes were used to determine other insulating properties like particle size distribution, specific gravity, bulk density, solid density, water absorption, apparent porosity, permeability to air, refractoriness, thermal shock resistance, modulus of rupture, linear shrinkage and thermal conductivity.
The samples were collected from three different locations in the territory, namely Sheda, Abaji and Karimu, and labeled A, B, and C. A complex system is thereby characterised by its inter-dependencies, where as a complicated system is characterised by its layers.Complexity is generally used to characterize something with many parts where those parts interact with each other in multiple ways, culminating in a higher order of emergence greater than the sum of its parts.The values for modulus of rupture and thermal conductivity averaged 81 MN/m2 and 0.494 W/mo K. The refractoriness of all the samples were 1300o C and this showed that they could be used as insulating materials. Agha O A (1998) Testing of local refractory clay for producing furnace lining bricks. The values for specific gravity, bulk density, solid density and apparent porosity averaged 2.75, 2.04 g/cm3 , 3.18 g/cm3 , and 13% respectively and they were within the internationally accepted range.
