New reforms in science education call for three-dimensional learning by integrating disciplinary core ideas, science and engineering practices, and "crosscutting concepts" (CCCs). These reforms defined the new term, crosscutting concept (CCC), as a lens that has explanatory power across disciplines. To describe how researchers are…

The merits of three approaches (explicit, reflective and implicit) to Nature of Science (NOS) teaching and learning in the context of a summer research experience on high school student participants' NOS ideas were explored in this study. The effectiveness of explicit over implicit approaches has been demonstrated in school contexts, but less…

Science education frameworks in the United States have moved strongly in recent years to incorporate more dimensions of learning, including measuring student use of scientific practices employed during scientific inquiry. For instance, the Next Generation Science Standards and related multidimensional frameworks adopted or adapted recently by more…

A large body of research has examined students' conceptions of evolution and their relationships to acceptance of evolution. Proficiency in statistical and probabilistic reasoning has long been considered to be an essential feature of evolutionary reasoning, yet almost no empirical work has explored these putative connections. The RaPro…

Although extensive research has shown the educational value of different types of interactive visualizations on students' science learning in general, how such technologies can contribute to English learners' (ELs) understanding of complex scientific concepts has not been sufficiently explored to date. This mixed-methods study investigated how…

Instructional tasks are key features of classroom practice, but little is known about how different components of tasks--such as selecting or designing tasks for a lesson, launching, and implementing them with students--shape the conditions for students' intellectual engagement in science classrooms. Employing a qualitative multiple case study…

Few research studies in science education have looked at how stories, proverbs, and anecdotes can be used as scaffolds for learning. Stories, proverbs, and anecdotes are cultural tools used in indigenous communities to teach children about their environment. The study draws on Bruner's work and the theory of border crossing to argue that stories,…

Understanding the energy changes that occur as atoms and molecules interact forms the foundation for understanding the macroscopic energy changes that accompany chemical processes. In order to identify ways to scaffold students' understanding of the connections between atomic-molecular and macroscopic energy perspectives, we conducted a…

Empirical studies have reported difficulties, confusion, and lack of understanding among students at all levels of instruction regarding the issue of weight--gravitation--weighing relationships. This study examined the impact of a new conceptual framework of weight, on a small group of 7th-grade students (N?=?14) in a middle school in Israel. This…

Although taxonomic proficiency is a prerequisite for understanding ideas central to biology, previous research has established that learners frequently misclassify animals by not following the tenets of accepted taxonomic rubrics. This has immediate relevance with the recently revised English National Curriculum now requiring concepts of animal…

This research studied a group of three preservice elementary teachers creating a narrated stop-motion animation (Slowmation) from start to finish in 3?hours to explain the challenging concept of "phases of the moon" to elementary school children. The research questions investigated the preservice teachers' learning before and after the…

This study investigated the conceptual pathways of 19 Grade 11 introductory chemistry students (age 16-17) as they participated in a multirepresentational instruction on the particulate nature of matter (PNM). This study was grounded in contemporary conceptual change theory, in particular, research on students' conceptual pathways that focuses on…

The connection between the molecular-level structure of a substance and its macroscopic properties is a fundamental concept in chemistry. Students in college-level general and organic chemistry courses were interviewed to investigate how they used structure-property relationships to predict properties such as melting and boiling points. Although…

We propose a new model of the factors influencing acceptance of evolutionary theory that highlights a novel variable unexplored in previous studies: the feeling of certainty (FOC). The model is grounded in an emerging understanding of brain function that acknowledges the contributions of intuitive cognitions in making decisions, such as whether or…

We raise concerns about the current state of research and development in formative assessment, specifically to argue that in its concentration on "strategies for the teacher", the literature overlooks the "disciplinary substance" of what teachers and students assess. Our argument requires analysis of specific instances in the literature, and so we…
