This study compared the effects of direct immersive virtual reality (IVR), a physical laboratory, and teacher-modelled observational virtual reality on gifted sixth-grade students’ chemical change knowledge and attitudes towards science classes and laboratories. A three-group pretest-posttest quasi-experimental design was used with 66 gifted sixth-graders (39 girls, 27 boys). Gifted students learned through direct IVR, a physical laboratory, or observational IVR based on teacher modelling. All groups received the same content, procedures, worksheets, and teaching time. Data were collected using the Chemical Change Knowledge Test and the Attitude toward Science Course and Laboratories Scale, then analysed through a 3 × 2 mixed-design ANOVA. The interaction between learning environment and time was significant for all variables. The physical laboratory group showed greater gains in attitudes towards learning science at school, science self-concept, and overall attitudes towards science. Observational IVR produced knowledge gains comparable to those of the physical laboratory group, but smaller gains in attitudes. Overall, the findings indicate that different laboratory environments support different learning outcomes among gifted sixth-grade students.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">583-599</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%">Orhan Ercan</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE EFFECTS OF MULTIMEDIA LEARNING MATERIAL ON STUDENTS’ ACADEMIC ACHIEVEMENT AND ATTITUDES TOWARDS SCIENCE COURSES</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%">healthy nutrition</style></keyword><keyword><style  face="normal" font="default" size="100%">Science Achievement</style></keyword><keyword><style  face="normal" font="default" size="100%">science attitudes</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2014</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2017/987-1519324524.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">13</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%">This study implemented multimedia learning material developed for the 5th grade science course topic &quot;Food and Healthy Nutrition&quot; and examined its effect on students' academic achievement and science attitudes. The study used a control group, a pre-test-post-test quasi experimental research design, and a convenience sample consisting of 62 5th grade students. The research instruments were an achievement test and a science attitude scale. During the implementation process the experiment group learned using multimedia learning material and the control group learned with traditional methods. Data were analyzed using an independent-samples t test, a paired-samples t-test, and ANCOVA statistics. According to the findings there is a statically significant difference between post-test achievement scores of the experimental and control groups, with the experimental group scoring higher. Also there is a statically significant difference between students' post-test scores in terms of gender, favoring females over males. In terms of science attitude there is also a significant difference between post-test scores of the experimental and control groups. In conclusion it may be said that multimedia learning promotes more effective learning in science education.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">608–621 </style></section></record></records></xml>
