Potency of Inter-Personality and Family Demography in Predicting Other Personality Factors Of University Students in Anambra State, Eastern Nigeria (Biafra) (Published)
The study examined “potency of inter-personality and family demography in predicting other personality factors in Anambra State, Eastern Nigeria (Biafra)”. Objective is the likelihood of people’s behaviours and family demography predicting their other behaviours. Students (n=101) of Chukwuemeka Odumegwu Ojukwu University, Igbariam Campus, Anambra State, Eastern-Nigeria (Biafra), sampled using cluster and incidental techniques participated. Big-Five Personality Inventory of convergent validity .97 and Split-half reliability .75 was used. Cross-sectional and correlational designs, plus multivariate hierarchical regression were adopted. Findings: “Agreeableness” significantly predicted “conscientiousness”, and “negative emotionality”; “Conscientiousness” significantly predicted “negative emotionality”, and “open-mindedness”; “Birth order” significantly predicted family number of children; “Number of children”, “family socio-economy”, and “Christian denomination” were substantially non-significant negative predictors of personality; finally “Extraversion” was non-significant positive predictors of personality. More cross-cultural studies on the topic are recommended. Christian religion should re-appraise their personality shaping roles to be functionally effective.
Enhancing Chemistry Students’ Retention of Redox Reaction Concept through Intervention with Advance Organizers (Published)
This study investigated the potency of advance organizers strategies in enhancing chemistry students’ cognitive levels retention of redox reaction concept. A pre-test, post test, control group, quasi-experimental design was adopted. Two hundred and twenty (220) senior secondary two (SS2) chemistry students (118 males and 102 females) purposively sampled from the target population in Obio/Akpor education zone of Rivers State, Nigeria, constituted three non-equivalent intact classes that participated in the study. Data was collected using a Redox Reaction Concept Retention Test (RRCART) instrument with Kuder-Richardson’s formula 20 reliability co-efficient of 0.90. Mean, standard deviation and percentages as well as analysis of covariance and Scheffe’s post hoc analysis were used for data analysis at 0.05 alpha level. Findings revealed that graphics advance organizers strategy consistently produced the highest retention mean gain and therefore was most effective in enhancing the retention abilities of chemistry students in redox reaction concept at all levels of the cognitive domain. Gender did not significantly influence the retention ability of students in redox reaction concept. It was recommended among others that chemistry teachers and educators should adopt graphics and textual advance organizers strategies and resources to effectively and efficiently teach redox reaction concept so as to promote conceptual learning over rote memorization.
