Science teacher trainees in a school attachment programme

Amedeker M.K. (Routledge, 2002)

Changes in the preparation of pre-service teachers at the University College of Education Winneba (UCEW) in Ghana, introduced in 1993, established closer links between the University College and the Basic Schools (BS) in ...
Learning to Teach Sport Education: Misunderstandings, Pedagogical Difficulties, and Resistance

Mccaughtry N.; Sofo S.; Rovegno I.; Curtner-Smith M. (2004)

This study used cognitive developmental theory to analyze how teachers learn to teach sport education. Two groups of undergraduate pre-service teachers were studied, one group during their secondary methods and corresponding ...
Application of a novel technique for band sawing using a tip-inserted saw regarding surface profiles

Okai R.; Tanaka C.; Ohtani T.; Iwasaki Y. (2005)

One way of achieving a successful forest management leading to biodiversity conservation is to ensure that wood is processed in an efficient manner. The authors succeeded in developing a new technology for bandsawing using ...
Automatic determination of fiber orientation on OSB surface using line detection method based on small eigenvalue analysis

Hu C.; Tanaka C.; Okai R.; Ohtani T. (2005)

The modulus of rupture (MOR) which is the key to the strength of oriented strand board (OSB) depends on the fiber orientation on OSB surface. In order to improve the quality of OSB products, it is essential to optimize the ...
Optimisation techniques for minimising saw teeth deflection and lumber thickness variation

Okai R.; Mitchual S.J.; Frimpong-Mensah K. (2006)

Lumber size control is an essential element in maximising yield and productivity because a small reduction in rough green target size could lead to substantial savings in wood fibre. One of the key components of rough green ...
The derivation of the GAB adsorption equation from the BDDT adsorption theory

Caurie M. (2006)

The BET-like adsorption equation, popularly known as the GAB equation, was derived from the BDDT adsorption equation without changes to the bulk liquid properties of multilayer molecules. Without these changes the third ...
Influence of mechanical properties and mineral salts in wood species on tool wear of high-speed steels and stellite-tipped tools - Consideration of tool wear of the newly developed tip-inserted band saw

Okai R.; Tanaka C.; Iwasaki Y. (2006)

This paper is the third in a series of work done on a novel technique for bandsawing, which uses a tip-inserted saw, and is gaining increasing popularity in Japan. It builds up on previous reports on the novel technique ...
The effect of organic soil amendments on root-knot nematodes, soil nutrients and growth of carrot

Agyarko K.; Kwakye P.K.; Bonsu M.; Osei B.A.; Frimpong K.A. (2006)

A study was conducted on a Haplic Acrisol at the Technology Village of the University of Cape Coast, Ghana to assess the impact of ground neem (Azadirachta indica A. Juss) leaves-poultry manure on root-knot nematodes, soil ...
Technical expertise development in secondary technical schools: Effects of ICT-enhanced 4C/ID learning environments

Sarfo F.K.; Elen J. (2006)

This study assessed the effectiveness of powerful learning environments (PLE), developed in line with the specifications of the 4C/ID-model, and the additional effect of ICT for fostering the development of technical ...
A note on the effect of Gliricidia sepium leaf meal on the growth performance and carcass characteristics of broiler chickens

Kagya-Agyemang J.K.; Takyi-Boampong G.; Adjei M.; Karikari-Bonsu F.R. (Polish Academy of Science, 2007)

A five-week feeding trial was conducted using 180 Cobb commercial broiler chickens to study the inclusion of sun dried Gliricidia sepium leaf meal (GLM) in broiler diets. The 21-day-old chickens were randomly allocated to ...
Performance of Stylosanthes hamata in the rangelands of northern Ghana

Annor S.Y.; Cofie J.R. (2007)

Stylosanthes hamata (stylo) was introduced into communities in the Northern Savanna Zone of Ghana in 1994 for rangeland improvement through oversowing. The objective of this study was to assess the performance of S. hamata ...
Analysis of sawn lumber production from logging residues of branchwood of Aningeria robusta and Terminalia ivorensis

Okai R.; Boateng O. (2007)

One way of meeting the supply demands of the wood industry is through the reduction of waste in timber processing. It has been estimated in Ghana that for every tree felled, nearly 50% of the tree volume is left in the ...
Hysteresis phenomenon in foods

Caurie M. (2007)

It has been explained that hysteresis is a sorption phenomenon, which rests on temperature, Aw, moisture content and on surface energy Q. As temperature and Aw as environmental variables have opposite effects on moisture ...
Developing technical expertise in secondary technical schools: The effect of 4C/ID learning environments

Sarfo F.K.; Elen J. (2007)

In this study, the effectiveness of learning environments, developed in line with the specifications of the four components instructional design model (4C/ID model) and the additional effect of ICT for fostering the ...
The views of educational practitioners in Ghana on ICT use and instructional design practice for promoting quality education

Sarfo F.K. (2007)

Many ICT boosters are of the view that ICT on its own can promote quality teaching and learning. In line with this metaphor, the need to provide computers in the classrooms often takes precedence over training teachers to ...
Studies on reproducibility and accurate measurement of moisture content of wood samples using an electric moisture meter

Okai R. (2007)

Studies were conducted on reproducibility, and accurate measurement of moisture content of four wood samples using an electric moisture meter. Experimental results indicated that there was no clear relationship between ...
Growth performance of grasscutter (Thryonomys swinderianus) eating leaf and stem fractions of Guinea grass (Panicum maximum)

Annor S.Y.; Kagya-Agyemang J.K.; Abbam J.E.Y.; Oppong S.K.; Agoe I.M. (2008)

This study was carried out to determine the growth performance of grasscutters (Thryonomys swinderianus) when fed on leaf and stem fractions of guinea grass. Eighteen (18) three month old male grasscutters were randomly ...
