This paper gives an example of how to address the challenge of designing a learning progression that describes student thinking, with the necessary specificity to align instructional opportunities and assessment tools. We describe the Conceptual Underpinnings of Evolution project and the iterative process of developing a novel learning progression…

Scientific modeling, the practice of creating models such as "diagrams, analogies, and simulations" (NGSS Lead States 2013) allows students to develop and revise their own representations of the natural world and use them to generate predictions and explanations about scientific phenomenon. Research provides evidence for elementary…

Recent evidence points to the early elementary grades as a pivotal point for the development of science learning trajectories and achievement gaps. Using data from the Early Childhood Longitudinal Study, this study estimates the degree to which time spent on science and the breadth of science topics/skills covered predict science achievement in…

In this paper, we present a study of second graders' learning about the nature of matter in the context of content-rich, model-based inquiry instruction. The goal of instruction was to help students learn to use simple particle models to explain states of matter and phase changes. We examined changes in students' ideas about matter, the coherence…

Despite the abundance of research in Modeling-based Learning (MbL) in science education, to date there is only limited research on MbL practices among K-6 novice modelers. More specifically, there is no information on how young/novice modelers' modeling enactments look so that researchers and educators have an idea of what should be expected from…

Students can learn subjects more meaningfully through integrated education, as it helps them to link school education with their real lives. There is a strong need to develop an alternative integration method to promote effective implementation of integrated education at a classroom level. The purpose of this study was to develop a model for…
