The need to evolve an innovative approach that can improve the practical learning outcomes among technical college students necessitated this study. Thus, the present study investigated the effect of innovative pedagogy integration in electrical installation and maintenance works in technical colleges in Enugu and Lagos states of Nigeria. The study adopted a school-based randomised Solomon Four-Group Design involving a treatment group versus the control group. We selected three hundred and fifteen (315) technical college year two (TC II) electrical installation and maintenance work students who met the study’s inclusion criteria from the technical colleges in Enugu and Lagos state of Nigeria. The intervention consisted of eight weeks of innovative pedagogy treatment. Electrical installation and Maintenance Achievement Test (EMAT) were used for data collection. We used analysis of variance, t-test for independent samples, and Chi-Squared for data analysis. The outcome indicated that innovative pedagogy improved students’ learning outcomes and significantly affected students’ EMAT achievement among electrical installation and maintenance work students in the treatment group compared to their control group counterparts. The study showed, no significant main difference across all the control variables. Finally, there is no interaction effect of pre-test and treatment conditions. Thus, the current study suggests that technical college teachers should adopt innovative teaching approaches to improve students’ learning outcomes, mainly because access to teaching and learning resources is limited.

The Impact

Abstract Background Cardiac involvement is the main driver of outcome in ATTR amyloidosis. Advances in therapeutics hold potential in transforming the course of the disease but the impact on cardiac amyloid load is unknown. The aim of this study was to evaluate the impact of patisiran, a new double stranded RNA based gene silencing therapy and a stabilizer, diflunisal, on cardiac amyloid load as measured by CMR and T1 mapping, in patients with ATTR amyloidosis. Methods and results Thirty-two patients with hereditary cardiac amyloidosis were studied. Sixteen patients received treatment with patisiran, and sixteen control subjects did not receive any disease modifying treatment. Patients were assessed with echocardiogram, CMR, NT-proBNP and six-minute walk time measurements at baseline and at 1 year (Mean interval 11.45±3.08 months in treatment group, mean interval 12.82±5.06 months in the control group). CMR analysis comprised LV volumes, T1 mapping to measure the extracellular volume (ECV) occupied by amyloid, T2 mapping and late gadolinium enhancement imaging. At 1-year follow-up, there was a substantial reduction in cardiac amyloid burden, in keeping with cardiac amyloid regression in 45% of patients on treatment. Overall the treatment group showed a reduction in ECV at 1 year follow up compared to an increase in ECV at 1 year in the control group (−1.37%, 95% CI: −3.43 to 0.68% versus 5.02%, 95% CI: 2.86% to 7.18% respectively, p<0.001). The treatment group also showed an improvement in change in 6MWT at 1 year follow up compared to 6MWT at 1 year in the control group (−8.12 meters, 95% CI: −50.8 to 34.6 meters in the treatment group versus −132.27 meters, 95% CI: −216 to −48.6 meters in the control group, p=0.002). The treatment group showed a reduction in BNP at 1 year follow up compared to an increase in the control group (−567.87, 95% CI: −1288.90 to 153.15 in the treatment group versus 2004, 95% CI: 12.82 to 3995.45 in the control group, p<0.001). There was no significant difference from baseline and 1-year data between the control and treatment groups for the difference in echocardiographic parameters, native T1, T2. There was a significant reduction in the percentage of injected dose by 99Tc-DPD scintigraphy in treated patients at 1 year compared to baseline. Conclusions These findings provide the first compelling evidence of substantial cardiac amyloid regression in ATTR amyloidosis, as well as the potential for CMR to be used to track response in treated patients with ATTR cardiac amyloidosis. Combination therapy with transthyretin knock down and stabilizing agents may well be synergistic given enhanced stoichiometry of stabilizers in the face of much reduced plasma transthyretin concentration.

PURPOSE We conducted a randomized prospective trial in selected patients with fully resected high-risk stage I and II malignant melanoma. PATIENTS AND METHODS Interferon alfa-2a (IFN-alpha 2a) 20 x 10(6) U/m2 was administered three times each week for 12 weeks by the intramuscular route. Both the treatment group (n = 131) and the control group (n = 131) were evenly balanced with regard to relevant prognostic discriminants. RESULTS The median disease-free survival (DFS) time was 2.4 years for the IFN-alpha 2a group and 2.0 years for the observation group (log-rank P = 0.19). The median survival times were 6.6 years for IFN-alpha 2a and 5.0 years for observation (log-rank P = .40). For stage I patients (n = 102), there was no apparent therapeutic advantage from IFN-alpha 2a therapy. The DFS for stage II patients was a median of 10.8 months in the control group versus 17 months in the treatment group. The overall survival time was 4.1 years for the treatment group versus 2.7 years for the control group. The differences in DFS for stage II patient were significant in a Cox model. These results must be interpreted cautiously because of subset analysis. A severe flu-like toxicity occurred in 44% of patients, 13% lost at least 10% of their baseline weight, and 45% experienced a worsening of Eastern Cooperative Oncology Group (ECOG) performance score. CONCLUSION Our findings indicate trends that suggest a possible benefit for selected patients with high-risk malignant melanoma. The results will require further study in a larger patient population for confirmation.

Education prepares one for the world of work; hence, the adoption of the innovative instructional approach employed in the process of teaching and learning is key to the attainment of this goal. To mitigate students’ poor achievement in computer programming (CP), innovative pedagogy (IP) was adopted to make students become active learners in classroom learning. In this study, a quasi-experimental design was used and nonrandomized the subject with pretest and posttest. Students (N = 145) were nonrandomized to the treatment and control groups. The researchers conducted a repeated measure of analysis of variance to determine the change between the experimental and control groups. Students’ attributes were tested for differences by comparing categorical data with chi-square statistics. The interaction effect was determined using an analysis of covariance. The results revealed that the experimental group’s CP achievement test results outperformed those of the control group at posttest and retention tests. Furthermore, the findings of the study show that there is no significant difference in students’ academic achievement across ability levels and gender. Also, there is no interaction between the pretest and the IP. The study, therefore, recommends that computer educators should adopt innovative teaching practices in their day-to-day teaching since it is more creative, learner-centered, and improved student engagement.

The study developed the basic science information and communication technology (BSICT) instructional package based on Nigerian Junior Secondary School (JSS) curriculum and investigated its effect on the students' learning outcomes with the aim of improving them. The study employed the pre-test, post-test, control group quasi-experimental research design. From a population of all JSS in Osun State, a sample of 180 students from six intact classes in six purposively selected schools was taken. The experimental groups were taught using the BSICT package while the control groups were taught the same concepts without the package. Data was collected using the Basic Science Achievement Test and analysed. The results showed significant effects of the package on students' performance and retention ability in basic science. The study concluded that BSICT could be used to improve students' learning outcomes in basic science if properly proctored. Hence, the use of computer assisted instruction can be recommended for teaching and learning for improved performance and retention.
