to determine the validity of the multimedia module. Three instruments employed in
this study were expert validation, reliability and usability questionnaires. All the
instruments were valid and reliable for this study. The data were analysed using
percentage of expert agreement to detemine validity, Cronbach alpha for reliability
and mean for usability of the module.The finding shows that the developed
multimedia module has a good validity and reliability with 93.3% of expert agreement
and Cronbach alpha value 0.90. The Propos-Bio multimedia module also has a good
usability in ter.....
