Abstract
The study compared two digital packages - Digital Concept Maps Package (DCMP) and Digital Textual Notes Package (DTNP) for online Economics instruction in secondary schools in Nsukka LGA. Specifically, the study determined: effects of DCMP and DTNP on students’ mean achievement scores in Economics; influence of gender on students’ mean achievement scores; and interaction effect of packages and gender on students’ mean achievement scores. It was a quasi experimental pretest-posttest study. Population comprised of 986 senior secondary school (SS) 2 Economics students. The sample size was 176 SS2 Economics students purposively drawn from the 19 coeducational schools in Nsukka LGA. Instrument for data collection was Economics Achievement Test (EAT). It was face validated by seven experts. EAT has internal consistency reliability index of 0.72 using Kuder-Richardson and temporal stability reliability index of 0.87 using Pearson Product. Two experimental groups were exposed to DCMP and DTNP, respectively. Mean, standard deviation and ANCOVA at 0.05 level of significance were used data analysis. The findings revealed that both DCMP (pretest X̅=25.09; posttest X̅=41.78) and DTNP (pretest X̅=25.73; posttest X̅=40.76) enhanced students’ achievement in Economics. Gender (F = 0.002; = 0.963) and interaction effect of packages and gender (F = 0.242; p = 0.624) were not significant in students’ achievement in Economics. Based on the findings four recommendations were made.
