A web-based virtual lab and a low-cost MBL were proposed to help first-year engineering students build scientific models. Empirical research was done in a slope motion experiment. The participants were 118 first-year engineering students in Taiwan, and they were divided into a VL group and an MBL group. From the results of the questionnaire, these groups of students thought that the systems were usable and easy to use, and they expressed positive attitudes towards the labs. The post-test’s average score was higher than that of the pre-test for both groups, and the average posttest score of the VL group was better than that of the MBL group. From the students’ learning sheets, many students successfully manipulated the experimental variables and built correct models after gradual revision of earlier models. According to the results of the empirical research, these systems helped the students understand the meaning of the experiment and increased students' interests with hands-on labs. A comparison of the results of these two groups\suggests the integration of VL and MBL to facilitate students’ learning.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">157-173</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Nazan   Kunduz</style></author><author><style face="normal" font="default" size="100%">Nilgün  Seçken</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DEVELOPMENT AND APPLICATION OF 7E LEARNING MODEL BASED COMPUTER-ASSISTED TEACHING MATERIALS ON PRECIPITATION TITRATIONS</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">7E learning model</style></keyword><keyword><style  face="normal" font="default" size="100%">animation</style></keyword><keyword><style  face="normal" font="default" size="100%">chemistry education</style></keyword><keyword><style  face="normal" font="default" size="100%">educational computer games</style></keyword><keyword><style  face="normal" font="default" size="100%">precipitation titrations</style></keyword><keyword><style  face="normal" font="default" size="100%">virtual lab</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2013</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2015/987-1425811451.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">12</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">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 “precipitation titrations” 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.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">784-792</style></section></record></records></xml>
