Enhancing Leaners’ Motivation and Academic Achievement in Basic Science Using Printed Library Resources

In Enugu State, Nigeria, the researchers investigated the effects of printed library resources on students\u27 motivation and academic achievement in basic science. The study used a quasi-experimental research design using 58 primary 5 pupils in public primary schools in Enugu State. Purposive sampling was used to select a sample size for the study. The achievement exams Basic Science Achievement Test (BSAT) and Motivation Scale were used to collect data (BSMS). Using Kuder-Richardson\u27s formula 20 and the Cronbach Alpha technique, the instruments\u27 reliability indices were judged to be 0.81 and 0.76, respectively. To answer the study questions, bar charts were used, while analysis of variance was used to test the null hypotheses at the 0.05 level of significance. Printed library resources improved significantly learners\u27 motivation and achievement in basic science according to the findings. The researchers advised that the government should make available printed library resources for use by the primary school teachers

Validation of coronavirus-2019 phobia scale using preschool practitioners in urban and rural communities in Nigeria Implication for educational sociologists

Coronavirus-2019 (COVID-19) emerged in December 2019, causing significant changes in people’s social lives and other human activities. The outbreak halted educational activities throughout the world. The Nigerian experience was unique in that most people were skeptical about the pandemic’s existence. This practice contributed to the Nigerian people’s fear of the COVID-19 outbreak. However, in Nigeria, there has never been a validated or established Covid-19 phobia scale, necessitating this study. This study was a pure validation study on COVID-19 phobia scale (C19PS). The study area was south-east states and a sample of 386 preschool practitioners in urban and rural communities of South East States, Nigeria participated in the study. The eligibility criteria include being a preschool teacher and demonstrating signs of COVID-19 phobia. The validation of the C19PS was done by subjecting the data gathered to principal axis factoring analysis with varimax rotation. The model fit for the data was tested using root mean square error of approximation and comparative fit index. It was found that the Kaiser-Meyer-Olkin value of .845 for the measure of the adequacy of the sample size. There was also a significant Bartlett’s test of sphericity (P<.05). This implies that the correlation matrix for the C19PS is not an identity matrix. It was revealed that C19PS had good overall reliability (a=.896) and model fit (Root mean square error of approximation=.042, comparative fit index=.943) in a sample of Nigerian preschool practitioners. As a result, C19PS was recommended as a trustworthy tool for identifying persons who suffer from COVID-19 phobia.https://www.journals.elsevier.com/medicineam2023Science, Mathematics and Technology Educatio

Effect of priming interval on reactogenicity, peak immunological response, and waning after homologous and heterologous COVID-19 vaccine schedules: exploratory analyses of Com-COV, a randomised control trial

BackgroundPriming COVID-19 vaccine schedules have been deployed at variable intervals globally, which might influence immune persistence and the relative importance of third-dose booster programmes. Here, we report exploratory analyses from the Com-COV trial, assessing the effect of 4-week versus 12-week priming intervals on reactogenicity and the persistence of immune response up to 6 months after homologous and heterologous priming schedules using the vaccines BNT162b2 (tozinameran, Pfizer/BioNTech) and ChAdOx1 nCoV-19 (AstraZeneca).MethodsCom-COV was a participant-masked, randomised immunogenicity trial. For these exploratory analyses, we used the trial's general cohort, in which adults aged 50 years or older were randomly assigned to four homologous and four heterologous vaccine schedules using BNT162b2 and ChAdOx1 nCoV-19 with 4-week or 12-week priming intervals (eight groups in total). Immunogenicity analyses were done on the intention-to-treat (ITT) population, comprising participants with no evidence of SARS-CoV-2 infection at baseline or for the trial duration, to assess the effect of priming interval on humoral and cellular immune response 28 days and 6 months post-second dose, in addition to the effects on reactogenicity and safety. The Com-COV trial is registered with the ISRCTN registry, 69254139 (EudraCT 2020–005085–33).FindingsBetween Feb 11 and 26, 2021, 730 participants were randomly assigned in the general cohort, with 77–89 per group in the ITT analysis. At 28 days and 6 months post-second dose, the geometric mean concentration of anti-SARS-CoV-2 spike IgG was significantly higher in the 12-week interval groups than in the 4-week groups for homologous schedules. In heterologous schedule groups, we observed a significant difference between intervals only for the BNT162b2–ChAdOx1 nCoV-19 group at 28 days. Pseudotyped virus neutralisation titres were significantly higher in all 12-week interval groups versus 4-week groups, 28 days post-second dose, with geometric mean ratios of 1·4 (95% CI 1·1–1·8) for homologous BNT162b2, 1·5 (1·2–1·9) for ChAdOx1 nCoV-19–BNT162b2, 1·6 (1·3–2·1) for BNT162b2–ChAdOx1 nCoV-19, and 2·4 (1·7–3·2) for homologous ChAdOx1 nCoV-19. At 6 months post-second dose, anti-spike IgG geometric mean concentrations fell to 0·17–0·24 of the 28-day post-second dose value across all eight study groups, with only homologous BNT162b2 showing a slightly slower decay for the 12-week versus 4-week interval in the adjusted analysis. The rank order of schedules by humoral response was unaffected by interval, with homologous BNT162b2 remaining the most immunogenic by antibody response. T-cell responses were reduced in all 12-week priming intervals compared with their 4-week counterparts. 12-week schedules for homologous BNT162b2 and ChAdOx1 nCoV-19–BNT162b2 were up to 80% less reactogenic than 4-week schedules.InterpretationThese data support flexibility in priming interval in all studied COVID-19 vaccine schedules. Longer priming intervals might result in lower reactogenicity in schedules with BNT162b2 as a second dose and higher humoral immunogenicity in homologous schedules, but overall lower T-cell responses across all schedules. Future vaccines using these novel platforms might benefit from schedules with long intervals
