Effect Of Class Size In Effective Teaching And Learning Of Chemistry In Public Senior Secondary Schools

The production of the soap was carried out using all the necessary equipments like the reactor, mould, stirrer, hygrometer guage etc. and all the required reagents for soap production in correct proportion. In the production, palm kernel oil (P.K.O) was used instead of tallow or grease. This was because soap produced from grease or tallow tends to dissolve slowly at room temperature, whereas, soap of palm kernel oil product gives a qui […]

Some scholars have found out from some states of the federation that the results of chemistry students in senior secondary School certificate examination have been always poor. “Among students who enroll in chemistry, the results in chemistry are very poor. We found out that the chemistry teachers who teach them are competent enough. Achievement in science, like chemistry is affected by the teaching personality of the science teachers […]

Comparative study of student performance in WAEC biology, chemistry and English from 2004 – 2008 in Enugu North Local Government Area. In this study the researchers want to know to what extent the student performance in English varies from the student’s performance in biology and to what extent the student performance in English vary from chemistry. This has motivated the researcher towards reviewing all the related literature necessar […]

Inflammation is a complex biological response of vascular tissue to harmful stimuli such as pathogen, damage cells or irritants (Ryan & Majno, 1983). The urgency generated by increased rate of stroke, atherosclerosis attribute due to prolonged use of cyclooxygenase-1 and Cyclooxygenase- 2 inhibitors have accelerated anti-inflammatory drug research over the last decade while synthetic pharmaceutical agents continued to dominate rese […]
