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…

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…

This study examines and compares how developers designed two primary science curricula to support teacher adaptation and enable use of innovative materials at scale. The two cases--"Literacy Science" (a science and literacy curriculum for grades 2-5) and "Science as Inquiry" (a curriculum focused on matter for grades 3-5)--were…

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…

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…

In this year-long randomized control trial (RCT), we evaluated the effectiveness of a year-long, intensive, and structured virtual professional development (VPD) accompanying science-integrated English-as-second-language (ESL) instructional intervention on 187 second grade English learners' English language and literacy development in suburban…

This paper reports findings from a two-year investigation on the impact of a professional development (PD) program on second grade teachers' science teaching practice, particularly of the Next Generation Science Standards Science and Engineering Practices (NGSS SEPs). The aims of this study were three-fold: 1) identify which SEPs teachers enacted…

We examine the promise, usability, and feasibility of an intelligent tutoring system (ITS) to improve the vocabulary and language proficiency in science and social studies of Latinx second grade English learners (ELs). Participants were 217 ELs attending English only programs or bilingual programs. Findings from the clustered randomized control…

Background: To succeed in school, young children must acquire the domain and vocabulary knowledge needed to read complex texts. Despite the growing literacy demands in the 21 century, fewer than 5% of US school children in the early elementary grades can evaluate complex nonfiction texts and there are larger gaps based on family income and student…

Our paper builds on the construct of the zone of proximal development (ZPD) (Vygotsky in Mind in society: the development of higher psychological processes, Harvard University Press, Cambridge, 1978) to analyze the relationship between students' answers and the help they receive as they construct them. We report on a secondary analysis of…

Computers, laptops, interactive whiteboards, and iPads make regular appearances in our daily lessons, but are they being used to their fullest potential? In an effort to use technology with students in a meaningful way, the authors incorporated a free app and online graphing resource into a second-grade lesson on the characteristics of a lake…

School closures because of natural phenomena, such as COVID-19, underscore the importance of effective distance learning strategies when there are no in-school alternatives. Our study describes the implementation of a multimedia science program before and after school closure due to COVID-19 in a variety of ways depending on schools'…

The main purpose of this study was to explore the factors mediating the translation of second grade teachers' nature of science (NOS) views into classroom practice after completing a graduate level NOS course. Four second grade in-service elementary teachers comprised the sample of this study. Data were collected from several sources during the…

This article describes an integrated unit designed to teach second graders about the phases of the Moon. The science department at the author's school had been reshaping their curriculum to match their state standards as well as the "Next Generation Science Standards" ("NGSS"). Their primary goal was for students to be…

This case study introduces the notion of an operative system to describe elementary teachers' knowledge and practice. Drawing from complex systems theory, the operative system is defined as the network of knowledge and practices that constituted teachers' work within a lesson study cycle. Data were gathered throughout a lesson study cycle in which…
