Bringing about conceptual change in the science classroom can be difficult because most concepts are complicated and often counter-intuitive in the teaching and learning of science concepts. A review of the literature indicates that the conceptual change model, CCM can be an effective teaching technique in addressing misconceptions and improving conceptual understanding when it comes to science instruction. The aim of this research was to find out the effect of the conceptual change model on pre-service teachers’ conceptual understanding regarding the topic of forces and motion. Using data from tests and questionnaires, the research questions were answered by quantitatively analyzing the collected data. The analysis revealed that there is a statistically significant correlation between the conceptual change model and the conceptual understanding of the pre-service teacher participants. Overall, the results provide evidence in support of the effectiveness of the conceptual change model, CCM in addressing misconceptions and promoting conceptual understanding of forces and motion among the pre-service teacher participants that volunteered for this research. The results also indicate that the CCM is a teaching model which must be considered by science educators and teachers as they seek to address issues related to misconceptions and conceptual understanding in the teaching of science topics. </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%">499-515</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%">Astrid K Northrup, PE</style></author><author><style face="normal" font="default" size="100%">Andrea   C.

Uncovering what challenges U.S. schools in general—and rural U.S. schools in the unique environment of more mountainous regions of the U.S. in particular—face in implementing new curricula is not well established in the scholarly literature base. If reform advocates are able to anticipate implementation challenges, they might be more effective in facilitating needed changes.  In response, the overarching research question is addressed: What are the challenges of delivering multi-age computer science in the rural, mountain regions of the western U.S.? This two-phase research project first identifies the anticipated challenges to implementing the curriculum by curriculum designers (Phase 1), and then goes on to compare those anticipated challenges to those identified by classroom teachers after completing a teacher training program (Phase 2). Thirteen teachers completed the training program in May and July of 2021, and five were selected to be interviewed. Transcripts of the interviews were analyzed in open, axial, and selective coding to identify recurrent and dominant themes. First, a qualitative methodology through the lens of the constructivist theory was used. Then, conventional narrative inquiry methods were employed to investigate the narratives using thematic analysis. The Phase 1 concerns of adhering to curriculum standards and using appropriate programming languages were contrasted to the Phase 2 themes of the future importance of coding for all students, confidence in pedagogy, the difficulty of coding, and issues of approval and safety. The results of this study serve as a bridge between the mandates created by education leaders and the actual experiences of the participating teachers tasked with delivering the curriculum. </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%">353-370</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%">Andrea   C.

The answer is both. Computer science and engineering concepts are typically found almost exclusively in collegiate engineering and technology programs. Given its importance across the 21st Century workforce, arguably these concepts should be taught at all pre-collegiate grade levels. This study, specifically focused on pre-collegiate teachers’ increased confidence and subsequent use of robotics, indicates that designed professional development (PD) focused on simple computer programming approaches (e.g. LEGO MindStorm® kits) can propel pre-collegiate teachers to integrate new, challenging computer controlled robotics into their instruction. Surveys, content knowledge quizzes, and artifacts show teachers readily developed sufficient confidence and knowledge in producing lessons embedded with computer programming and robotics. Targeted classroom-ready instruction and modifiable computer programs appear to enhance pre-collegiate teacher knowledge of and confidence in robotics use. Considering overall self-rankings and content, pre-collegiate teacher pre-post scores increased. With these results, the authors argue why approaching computer science as both a strict science and art form is essential in PD.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">6-15</style></section></record></records></xml>
