This research is aimed to analyze the validity and effectiveness of PIL model. This research was conducted using focus group discussions of experts that consisted of three science education experts and applies quasi-experiment of one group pre-test and post-test design to 144 students in East Java, Indonesia. Before applying the lesson using the PIL model, the students are given pre-test and after accomplishing the learning, the students are given post-test. The data collected from pre-test and post-test then is further analyzed by means of validity coefficient (rα), Cronbach’s alpha (α), pair t-test, n-gain and ANOVA. The result of research shows that rα = .75 and α = .92 is for content validity; rα = .79 and   α = .99 is for construct validity, so that PIL model is validity and reliability qualified. In addition, there are increasing scores of physics problem solving skills and self-directed learning skills of α = 5% with moderate category of n-gain consistent in a limited trial test and of high category in a broader trial test for all groups.</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%">651-665</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%">Meng-Fei Cheng</style></author><author><style face="normal" font="default" size="100%">Jang-Long Lin</style></author><author><style face="normal" font="default" size="100%">Ying-Chi Chang</style></author><author><style face="normal" font="default" size="100%">Hsiao-Wen Li</style></author><author><style face="normal" font="default" size="100%">Tsung-Yu Wu</style></author><author><style face="normal" font="default" size="100%">Deng-Min Lin</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DEVELOPING EXPLANATORY MODELS OF MAGNETIC PHENOMENA THROUGH MODEL-BASED INQUIRY</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%">explanatory models</style></keyword><keyword><style  face="normal" font="default" size="100%">magnetism</style></keyword><keyword><style  face="normal" font="default" size="100%">undergraduate students</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%">June/2014</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2015/987-1437679161.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%">The main purpose of this study was to bridge the gap between how scientists practice and how students learn science. To achieve this, an innovative student-centered curriculum was designed to teach 42 undergraduate students. The program involved scaffolding activities, an interactive computer simulation, and reflection on scientific modeling criteria to address the students’ difficulties in reasoning at the microscopic level and the scientific evaluation of their models during their development of an explanatory model of magnetism. To address the students’ difficulties in reasoning at the microscopic level and the scientific evaluation of their models during their development of an explanatory model of magnetism, the program involved scaffolding activities, an interactive computer simulation, and reflection on scientific modeling criteria. The results of the study indicated that more than half the students developed scientific and coherent microscopic N-S dipole models to explain observed magnetic phenomena, and students’ understanding of the nature of models was significantly enhanced after the instruction. This study contributes to modeling theory and the methods that can help students self-develop scientific models of magnetism as opposed to rote learning.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">351–360 </style></section></record></records></xml>
