	abstract = {The purposes of this study are to develop a computer-assisted instructional material, which involves animations, virtual lab and educational computer applications, based on 7E learning model towards the methods of Mohr and Volhard in the unit {\textquotedblleft}precipitation titrations{\textquotedblright} delivered in some quantification chemistry courses and to identify the effects of this material on student achievement. The study employs the design of quasi-experimental with control and experiment groups to which pre- and post-test were administered. The participants of the study includes 89 vocational high school students. The data were collected through the administration of the test which was used as both pre- and post-test. The Cronbach alpha coefficient of the achievement test was found to be 0.756. The findings obtained were analysed through t-tests. The findings indicate that post-test scores of experiment group and control group on the achievement test were statistically significant different. This difference indicates that the software has positive effects on student achievement.},
