The goals of science education include providing students with real-world learning experiences that connect directly to learning objectives and deepen student interest in science. Learning experiences that occur outside of the science classroom can help science educators respond to these goals. To encourage the use of learning environments beyond…

In-service teachers implementing a science, technology, engineering, and math (STEM) curriculum centered on computational thinking (CT) work with unique content and pedagogical experiences. Understanding how curriculum design and teacher professional development affect curriculum implementation can help researchers understand the critical aspects…

This study describes the design and implementation of a science outreach program (elementary; 2nd-5th) and its associated student outcomes. Key features of the program include: (a) phenomenon-based, NGSS-aligned curriculum designed by science education experts and influenced by educational, sociocultural, and cognitive science theories, (b) active…

We conducted a multi-year study of specialization in elementary mathematics and/or science, using data drawn from a local sample of teachers and a nationwide sample of principals. Using the theory of planned behavior, we compare and contrast teacher and principal views and decision-making processes related to elementary content specialization…

This multiple-case study examined constraints encountered by early career elementary school teachers as they try to deliver high-quality science instruction. Four first-year teachers, who expressed confidence in their preparation and enthusiasm for teaching science, were asked to reflect on the most effective strategies for teaching elementary…

This study investigates whether elementary science teachers participating in a four-week professional development workshop develop new understandings about classroom discourse and whether they are able to implement strategies toward teaching science as student-to-student discourse. Perspectives and the extent of teacher use of discourse strategies…

Mathematics and science have similar learning processes (SLPs) and it has been proposed that courses focused on these and other similarities promote transfer across disciplines. However, it is not known how the use of these processes in lessons taught to children change throughout a preservice teacher education course or which are most likely to…

This study examined primary grades students' achievement on number sense tasks administered through an Internet-based formative assessment tool, Assessing Math Concepts Anywhere. Data were analyzed from 2,357 students in teachers' classrooms who had participated in a year-long professional development program on mathematics formative assessment,…

The National Research Council emphasizes the centrality of discourse and practices associated with constructing, evaluating, and using scientific explanations. These expectations increase already daunting challenges for those who teach science at the elementary school level. This study followed a multiparticipant case study approach examining…

Scaffolding is a complicated construct that can take many forms, including both written and verbal forms. This research study focused on three elementary science classrooms where students were using a series of written scaffolds to guide explanation building. In each classroom, data were collected to document and study an additional type of…

The aim of this study was to examine the concept development of decimal numbers in 244 Chinese elementary students in grades 4-6. Three grades of students differed in their intuitive sense of decimals and conceptual understanding of decimals, with more strategic approaches used by older students. Misconceptions regarding the density nature of…

The aim of this study is to analyze the effects of project-based learning on students' academic achievement, attitude, and retention of knowledge in relation to the subject of "Electricity in Our Lives" in a fourth-grade science course. The study was conducted in a quasi-experimental design as a "pre-test, post-test with…

Chemical principles are taught in elementary education across much of the United States because the "National Science Education Standards" include concepts about the nature of matter, states of matter, and changes in matter among other science concepts within the first to fifth grade levels. "Chemicals" is a word related to the nature of matter…

Numerous studies have been conducted regarding alternative conceptions about animal diversity and classification, many of which have used a cross-age approach to investigate how students' conceptions change over time. None of these studies, however, have investigated teachers' conceptions of animal classification. This study was intended to…

Of great importance for achieving science education reform may be teachers' interest in science and enjoyment of science. This study explores the motivational qualities (rated for "interest," "fun," and "learning" value) of different levels of inquiry of hands-on class activities. The participants, 53 preservice teachers in two sections of a…
