Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly predict the other. The theoretical framework is the cognitive load theory (CLT). This theory expects teachers to know where to focus their teaching and how to assess their learners’ work to avoid unnecessary overloading of the working memory, which might affect their performance. The explanatory sequential mixed-method research design was employed with 410 grade 11 Physical Science learners in their intact classes. The participants wrote the learner achievement test (LAT) and responded to a semi-structured interview. The learners’ test scores were then used to run a statistical test. The Pearson correlation and regression showed that the justifications given by learners for choosing correct or incorrect multiple-choice options were not due to chance, and the results of the learner interviews supported the learners’ performance in the test. Moreover, the findings indicated that there was a positive correlation between problem-solving skills and conceptual reasoning where statistically, conceptual reasoning predicted learners’ problem-solving skills using regression analysis. </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%">615-637</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%">Dževdeta Dervić</style></author><author><style face="normal" font="default" size="100%">Džana Salibašić Glamočić</style></author><author><style face="normal" font="default" size="100%">Azra Gazibegović-Busuladžić</style></author><author><style face="normal" font="default" size="100%">Vanes Mešić</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">TEACHING PHYSICS WITH SIMULATIONS: TEACHER-CENTERED VERSUS STUDENT-CENTERED APPROACHES</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%">cognitive load theory</style></keyword><keyword><style  face="normal" font="default" size="100%">kinematics simulations</style></keyword><keyword><style  face="normal" font="default" size="100%">teaching materials</style></keyword><keyword><style  face="normal" font="default" size="100%">teaching strategies</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">April/2018</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2017/987-1523527472.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">17</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%">Teaching and learning with simulations is widely used in today's classrooms. Therefore, it is important to examine the factors that potentially influence the effectiveness of simulation-based teaching environments. The aim of this research was to compare the effectiveness of teacher-centered and student-centered Physlet-based classes about one-dimensional kinematics at the level of upper-secondary school. The student sample consisted of 43 students (mostly 15-year-olds). Within the teacher-centered approach the teacher ran and controlled the simulations, and students watched the simulations on the projection screen. In the student-centered approach the students had the opportunity to work through the simulations on their computers. At the post-test, students from the teacher-centered approach outperformed their peers when it comes to conceptual understanding of kinematics, but students from the students-centered approach were more successful in solving quantitative problems. The results of this research support the idea that a progression from teacher-centered to student-centered approach may be optimal for learning novel concepts.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">288-299</style></section></record></records></xml>
