Abstract
This study investigated the effect of remedial reading instruction on word recognition: implications for inclusive education in Nigeria. Two research questions were posed and two hypotheses formulated for the study. A quasi-experimental design was used. A sample size of 20 primary school pupils selected out of a population of reading disabled children of grade three streams in Nsukka local government area were assigned to treatment and control groups. All the pupils recommended and identified by grade three teachers and continuous assessment record in reading respectively were pre-tested using adapted diagnostic checklist for oral reading and the grade reader. At the end of the treatment session, the participants were post-tested with the same instrument. The data were collated and analyzed using mean and standard deviations to answer the questions. While t-test statistics was employed to test the null hypotheses. The result of the study among other things revealed that there was mean difference in remedial instruction on word recognition. However, these differences observed are insignificant…

ABSTRACT

The addition of silver ion proved to improve the photocatalytic activity of nitrogen doped titanium dioxide (TiON) photocatalyst for the destruction of micro organisms in the water. Ag/TiON exhibited different photocatalytic activity based on three different weight percent of silver 0.06, 0.6 and 6 wt%. Different techniques such as XRD, UV diffuse reflectance and BET analysis were used to characterize Ag/TiON photocatalysts prepared by incipient wetness techniques (impregnation). Our studies showed the importance and the role of silver in nitrogen doped TiO2 to promote separation of charge carrier. Metal particles acted as sinks of photogenerated electrons in semiconductors and thus prevented charge recombination in the semiconductor. Therefore, Ag/TiON was used as antibacterial photocatalyst to enhance its photocatalyic activity in the visible region. Degussa P25 (TiO2) was used as a reference…
