Computer-supported collaborative learning (CSCL) is a technology-driven inquiry-based approach that encourages social interaction and shared knowledge construction in completing computer-aided tasks. Although there were researches carried out on CSCL, no research to date has extensively examined how CSCL enhanced with scripts containing…

The inclusion of engineering in the Next Generation Science Standards (NGSS) as a key component of K-12 science learning has provided both opportunities and challenges for elementary teachers. One challenge is integrating the design thinking processes that undergird engineering with core science concepts and current issues facing scientists and…

The ability to explain scientific phenomena is a key feature of scientific literacy, and engaging students' prior knowledge, especially their alternate conceptions, is an effective strategy for enhancing scientific literacy and developing expertise. The gap in knowledge about the alternate conceptions that novices have about many of Earth's…

In this study, we explore how cross-linguistic differences can contribute to children's scientific thinking. We compared first and third grade Chinese students' pre-instructional ideas of the earth expressed in clinical interviews with that of their English-speaking and Greek-speaking counterparts (as recorded in the literature). Inspired by a…

Concept inventories have been determined to be useful assessment tools for evaluating students' knowledge, particularly in the sciences. However, these assessment tools must be validated to reflect as accurately as possible students' understanding of concepts. One possible threat to this validation is what previous literature calls the item order…

Virtual globe programs such as Google Earth replicate real-world experiential learning of spatial and geographic concepts by allowing students to navigate across our planet without ever leaving campus. However, empirical evidence for the learning value of these technological tools and the experience students gain by exploration assignments framed…

As society becomes more technological, the need for scientific literacy grows . Part of scientific literacy is understanding the nature of science, which can be revealed, in part, by learning the historical context of current science concepts. History of science can be taught using scientific inquiry, scientific argumentation, and authentic…

The purpose of this qualitative study was to explore the use of 3-D printed models as an instructional tool in a middle school science classroom for students with visual impairments and compare their use to traditional tactile graphics for aiding conceptual understanding of geoscience concepts. Specifically, this study examined if the students'…

Students investigate local sand samples on a shoestring budget. This investigation reveals a fascinating Earth history that can address various interdisciplinary scientific topics, provide rich inquiry experiences, and move beyond the science classroom to integrate history, culture, and art. (Contains 3 figures and 14 online resources.)

Rivers are important surficial geologic processes that shape Earth's landscape. Students' conceptions of river features and processes serve as a foundation for their learning of new river concepts. Despite the importance of rivers and students' conceptions of them, little research has focused on identifying students' river conceptions. This study…

We investigated the effect of modeling and visualization resources on upper-division, undergraduate and graduate students' performance on an open-ended assessment of their understanding of physical hydrology. The students were enrolled in one of five sections of a physical hydrology course. In two of the sections, students completed homework…

High school biology teachers face many challenges as they teach evolution. State standards for evolution may provide support for sound evolution instruction. This study attempts to build upon previous work by investigating teachers' views of evolution standards and their evolution practices in a state where evolution standards have been…

Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high,…

The purpose of this study was to compare the effectiveness of the conceptual change oriented instruction through cooperative learning (CCICL) and traditional science instruction (TI) on 4th grade students' understanding of earth and sky concepts and their attitudes toward earth and sky concepts. In this study, 56 fourth grade students from the…

We use a construct-based assessment approach to measure learning progression of energy concepts across physical, life, and earth science contexts in middle school grades. We model the knowledge integration construct in six levels in terms of the numbers of ideas and links used in student-generated explanations. For this study, we selected 10 items…
