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…

This article describes one participating teacher's reflections on the generalizable strategies and structures from the professional development (PD) sessions that enabled her sensemaking, and how she translated these generalizations into her own second-grade classroom. Readers will be able to make their own useful generalizations from these…

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…

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…

In order to investigate the impact of science drawing instruction in a first-grade unit on carnivorous plants (CPs), we analysed student-produced drawings after explicit instruction in drawing scientifically (n=38), as well as compared their drawings with students in a previous implementation (year 1) who did not experience explicit drawing…

Collaborative-metacognitive use of science literature teaching approach (CMSLTA) refers to a researcher-made teaching approach from the Philippines that comprises four components, namely (a) formation of groups with three to four members who have varied reading comprehension ability and assigned rotating roles; (b) use of Scientific Method…

PEOE (predict, explain, observe, explain) is a strategy that supports conceptual change (Dial et al. 2009). "Conceptual change" is a process through which students can change their understandings, ideas, or beliefs (diSessa 1993; Konicek-Moran and Keeley 2015). This style of lesson allows students to express their scientific ideas…

This study examines how teachers can structure and use pretend play for teaching science, as well as the impact it has on students' agency, engagement, and discussion. Using interaction analysis, I examine two teachers in two classrooms (n=52) of first and second grade students (6-8 years) at a progressive elementary school. To shed light on how…

By bringing everyday phenomena into the classroom, teachers can more readily engage students in authentic scientific inquiry. When working with young children, the best phenomena are those that students can directly experience and investigate. Meaningful phenomena can be identified by watching children at play, listening to the conversations they…

In this investigation we propose new machine learning methods for automated scoring models that predict the vocabulary acquisition in science and social studies of second grade English language learners, based upon free-form spoken responses. We evaluate performance on an existing dataset and use transfer learning from a large pre-trained language…

The aim of the study was to examine the improvement of basic science process skills among second graders in science learning through an inquiry-based approach. The participants were 23 students from a second graders class. Participants were with the age around seven years old. The 5E model of inquiry-based approach was used to teach science. Mixed…

This 5E (Engage, Explore, Explain, Elaborate, and Evaluate) learning cycle integrating science and mathematics challenges and engages second-grade students in designing sail cars to solve an engineering problem. Students create and use line plots to organize their data to evaluate the strengths and weakness of their design solutions. Three…

When it snows, children are permitted to play outside during recess, which causes them to experience a variety of problems with their mittens or gloves. To align instruction with a problem student's experience in every day life, the authors developed and administered a short survey to second graders in an after school program. The authors found…
