An important goal in early childhood science education is students' development of academic language. However, scholars disagree on whether academic language must be explicitly taught or whether it can be learned through immersive science experiences. In this case study of a co-taught second grade classroom, we use positioning theory and framings…

It is urgent to ensure that science, technology, engineering, and mathematics (STEM) education meets the needs of our nation's increasingly diverse student population. This study examined whether a second-grade science program, Scientific Explorers, supported educational equity in STEM achievement for diverse student populations. Sociodemographic…

Using a verbal protocol, this study investigated how 38 second-grade students identify, describe, and interpret five types of commonly used visual graphics in science texts (i.e., cut-away diagrams, maps, captioned photographs, flow diagrams, and hybrids). Additionally, we explored the challenges students encountered when interpreting these…

In the early years of school, pupils have a very positive approach towards any new topic. Very often, the first contact with mathematics in the Italian school risks giving a limited and somehow negative impression, generating long-lasting effects. In this paper, we report on a series of experiences carried out in a second-year class of a primary…

The integration of engineering into existing school science curricula is arguably an effort to move beyond a mono-disciplinary goal of learning to one that teaches real-world applications and problem-solving in science. This study adopted dual theoretical lenses to scrutinize and compare the distribution of engineering elements in past and present…

Although the "Next Generation Science Standards" (NGSS) have three dimensions, the crosscutting concepts are often the forgotten dimension. One reason teachers may not emphasize the crosscutting concepts might be because they are broad, domain-general constructs that can be difficult to conceptualize in a meaningful way. Yet, when taught…

Background: This dissertation examines the pervasive influence of the white and colonial imaginary in shaping educational narratives that promote neoliberal success and capitalism, impacting the minds of successive generations. Contemporary youth perceive these narratives as detrimental, contributing to racial violence, climate-induced…

The limited time available to teach content area subjects, given the intense demands for literacy and math instruction, is a common concern in U.S. elementary schools. Unfortunately, this is especially true in schools that serve students who are less economically advantaged. With time being a perennial concern for educators, integrated…

This dissertation investigates how embodied learning within a Mixed Reality (MR) environment supports young children's science learning, focusing on a honeybee system. To do so, I designed three types of activities within an MR environment to enable young children to assume different perspectives as they create embodied models of honeybees as…

Semantic knowledge accumulates through explicit means and productive processes (e.g., analogy). These means work in concert when information explicitly acquired in separate episodes is integrated, and the integrated representation is used to self-derive new knowledge. We tested whether (a) self-derivation through memory integration extends beyond…

This study, which was reviewed through the Registered Report process, examined the initial efficacy of the Scientific Explorers program (Sci2) on second-grade students' science achievement. Sci2 is grounded in the growing body of empirical research on science instruction, embedding principles of explicit instruction within a guided inquiry-based…

In today's dynamic global economy, integrated units of study are particularly important. Students who are fluent in several disciplines and comfortable moving among them can make meaningful connections and maintain enhanced understandings (Sias et al. 2016). This article shares an integrated STEAM unit that is grounded in the science disciplinary…

Research has consistently highlighted the importance of promoting child-parent interactions. In this essay, we describe the development of MAKEngineering kits that provide collaborative learning experiences for children in Grades 2-6 to engage in engineering design tasks with members of their families in their home environment. First, we present…

Working with second-grade teachers, the authors designed a six-day integrated science and language arts unit to investigate the structures that insects use to make their sound vibrations. They were inspired by "The Very Quiet Cricket" (Carle 1990), which was used as the focus text for the unit, as well as "Bug Music"…

This study explores the importance of scientific observation in primary education, highlighting how the use of observation sheets can facilitate the acquisition of knowledge and the development of students' observation skills. In the research, 153 second-grade students were divided into three experimental groups, each group observing a woody plant…
