Baek, Hamin; Schwarz, Christina V. – Journal of Science Education and Technology, 2015
In the past decade, reform efforts in science education have increasingly attended to engaging students in scientific practices such as scientific modeling. Engaging students in scientific modeling can help them develop their epistemologies by allowing them to attend to the roles of mechanism and empirical evidence when constructing and revising…

Ginovart, Marta – Journal of Science Education and Technology, 2014
The general aim is to promote the use of individual-based models (biological agent-based models) in teaching and learning contexts in life sciences and to make their progressive incorporation into academic curricula easier, complementing other existing modelling strategies more frequently used in the classroom. Modelling activities for the study…

Wang, Zuhao; Chi, Shaohui; Hu, Kaiyan; Chen, Wenting – Journal of Science Education and Technology, 2014
Teachers' knowledge and application of model play an important role in students' development of modeling ability and scientific literacy. In this study, we investigated Chinese chemistry teachers' knowledge and application of models. Data were collected through test questionnaire and analyzed quantitatively and qualitatively. The result indicated…

García, Isaías; Benavides, Carmen; Alaiz, Héctor; Alonso, Angel – Journal of Science Education and Technology, 2013
This paper describes research on the use of knowledge models (ontologies) for building computer-aided educational software in the field of control engineering. Ontologies are able to represent in the computer a very rich conceptual model of a given domain. This model can be used later for a number of purposes in different software applications. In…

Peters, Vanessa L.; Songer, Nancy Butler – Journal of Science Education and Technology, 2013
This paper reports the results of a three-stage usability test of a modeling tool designed to support learners' deep understanding of the impacts of climate change on ecosystems. The design process involved repurposing an existing modeling technology used by professional scientists into a learning tool specifically designed for middle school…

Oh, Youn Joo; Jia, Yueming; Lorentson, Mhora; LaBanca, Frank – Journal of Science Education and Technology, 2013
The Educational and Career Interest scale, a self-report instrument measuring high school students' educational and career interest in STEM, was developed and validated in two studies conducted during 2010 and 2011. Study 1 included data from 92 high school students, in which exploratory factor analysis (EFA) was conducted with an initial…

Artun, Huseyin; Costu, Bayram – Journal of Science Education and Technology, 2013
The aim of this study was to explore a group of prospective primary teachers' conceptual understanding of diffusion and osmosis as they implemented a 5E constructivist model and related materials in a science methods course. Fifty prospective primary teachers' ideas were elicited using a pre- and post-test and delayed post-test survey consisting…

Fulmer, Gavin W.; Liang, Ling L. – Journal of Science Education and Technology, 2013
This study tested a student survey to detect differences in instruction between teachers in a modeling-based science program and comparison group teachers. The Instructional Activities Survey measured teachers' frequency of modeling, inquiry, and lecture instruction. Factor analysis and Rasch modeling identified three subscales, Modeling and…

Gardner, Joel; Belland, Brian R. – Journal of Science Education and Technology, 2012
Introductory biology courses form a cornerstone of undergraduate instruction. However, the predominantly used lecture approach fails to produce higher-order biology learning. Research shows that active learning strategies can increase student learning, yet few biology instructors use all identified active learning strategies. In this paper, we…

Kim, Hye Jeong; Miller, Heather R.; Herbert, Bruce; Pedersen, Susan; Loving, Cathy – Journal of Science Education and Technology, 2012
In this study, a wiki was integrated into a professional development model that systemically addresses early-career teachers' needs. This study was conducted to examine the impact of wiki-based professional development activities in a scientist-teacher professional learning community and focused on early-career teachers' perceptions of the role of…

Teksoz, Gaye; Sahin, Elvan; Tekkaya-Oztekin, Ceren – Journal of Science Education and Technology, 2012
The present study proposed an Environmental Literacy Components Model to explain how environmental attitudes, environmental responsibility, environmental concern, and environmental knowledge as well as outdoor activities related to each other. A total of 1,345 university students responded to an environmental literacy survey (Kaplowitz and Levine…

Nehm, Ross H.; Haertig, Hendrik – Journal of Science Education and Technology, 2012
Our study examines the efficacy of Computer Assisted Scoring (CAS) of open-response text relative to expert human scoring within the complex domain of evolutionary biology. Specifically, we explored whether CAS can diagnose the explanatory elements (or Key Concepts) that comprise undergraduate students' explanatory models of natural selection with…

van Borkulo, Sylvia P.; van Joolingen, Wouter R.; Savelsbergh, Elwin R.; de Jong, Ton – Journal of Science Education and Technology, 2012
Computer modeling has been widely promoted as a means to attain higher order learning outcomes. Substantiating these benefits, however, has been problematic due to a lack of proper assessment tools. In this study, we compared computer modeling with expository instruction, using a tailored assessment designed to reveal the benefits of either mode…

Hsu, Ying-Shao; Lin, Li-Fen; Wu, Hsin-Kai; Lee, Dai-Ying; Hwang, Fu-Kwun – Journal of Science Education and Technology, 2012
This study compared modeling skills and knowledge structures of four groups as seen in their understanding of air quality. The four groups were: experts (atmospheric scientists), intermediates (upper-level graduate students in a different field), advanced novices (talented 11th and 12th graders), and novices (10th graders). It was found that when…

Bouwma-Gearhart, Jana – Journal of Science Education and Technology, 2012
This paper reports on a qualitative, grounded-theory-based study that explored the motivations of science and engineering faculty to engage in teaching professional development at a major research university. Faculty members were motivated to engage in teaching professional development due to extrinsic motivations, mainly a weakened professional…
