This study examined the effects of digital video instruction and PowerPoint presentation on students’ academic achievement and interest in electoral system in government. The study employed a quasi – experimental which involved a 2 x 2 pretest – posttest non-equivalent control group factorial design. Two intact classes were used for the study. The population of the study comprised of 2, 800 Senior Secondary Class Two (SS II) Students. The sample of the study consisted of 170 senior secondary class two (SSII) government students. Using purposive sampling technique, two co-educational public secondary schools in Nsukka Local Government Area in Enugu State were selected for the study. Experimental group one is made up of 22 males and 46 female students while experimental group two is composed of 45 males and 57 female students. Experimental group one were assigned to digital video instruction (DVI) and PowerPoint presentation (PPPs) was assigned to experimental group two respectively. The instruments for data collection are the government achievement test in electoral system (GATES) and government interest inventory in electoral system (GIIES). The instruments were validated by experts in measurement and evaluation as well as experienced government teachers. An internal consistency of reliability of GATES was computed and found to be 0.76 using Kuder – Richardson formula 20(K-R 20) while for GIIES, an internal consistency reliability co-efficiency of 0.92 was obtained using Cronbach Alpha formula. Equally validated are the digital video instructional package and PowerPoint presentation package by experts in educational technology. Six research questions and six hypotheses were formulated for the study. The data collected were analyzed using mean and standard deviation as well as Analysis of Covariance (ANCOVA) which was used to test hypotheses at 0.05 significance level. The major findings of the study amongst others are as follows: Students taught electoral system using PowerPoint presentation performed better than students taught with digital video instruction. The students exposed to PowerPoint presentation (PPPs) had achievement mean scores of (x = 55.82) while the students exposed to digital video instruction (DVI) had achievement mean scores of (x = 49.76) in electoral system. The male students had a higher achievement mean scores of (x = 54.48) than the female students who had achievements mean scores of (x= 52.70) in electoral system. Students taught electoral system using digital video instruction (DVI) had a higher interest mean scores of (x = 97.28) than the students exposed to PowerPoint presentation (PPPs) who had interest mean scores of (x = 97.12). The result of the study also showed that the use of PowerPoint presentation had a significant effect on academic achievements and interest of students in electoral system. There was no interaction effect of instructional modes and gender on students’ achievement mean scores in electoral system as well as there was no interaction effect of instructional modes and gender on students’ interest mean score. These findings imply that there is need for government teachers to adopt the use of PowerPoint presentation (PPPs) and digital video instruction (DVI) in teaching and learning of government at the secondary school levels since they are found to be effective in electoral system. Based on these, it was recommended amongst others, that state government, ministries of education and professional associations should organize conferences, seminars and workshops to train teachers on the use of PowerPoint presentation and digital video instructional techniques. Finally, the limitations of the study, suggestions for further studies, summary as well as conclusions were highlighted.
