Students' ability to operate with increasingly more complex units has been shown to be a key factor in their conceptual development. These abilities have been characterized as "stages of units coordination." This article focuses on the domain of composing and decomposing composite units. Using data from a teaching experiment with a…

This study examined the development of the evaluation of praise that differs in congruence between what the praiser is praising (i.e. effort or ability) and what led the recipient to succeed. Children aged 7 and 8 years (second graders) and 10 and 11 years (fifth graders), as well as adults, made emotional and motivational evaluations about…

The purpose of the study was to examine the effectiveness of multimedia integrated CIRC learning management plan on grade 2 students' spelling ability. The research employed a one-group experimental design in which a learning management plan based on CIRC principles, with the integration of multimedia, was used as the main intervention. The…

The aim of this longitudinal research is to examine the development process of scientific and consistent knowledge structures of first, second, and third-grade students in middle school within the concepts of melting and dissolution according to conceptual change theories at the end of the education and training processes carried out in…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

Student engagement and well-being are critical for academic success and overall development. This Spotlight explores strategies to create supportive and engaging learning environments that foster student motivation and well-being. From re-emphasizing the importance of play in kindergarten to leveraging the power of outdoor learning, these articles…

We evaluate the effects of grade retention on students' academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third-grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the effects persist into middle school. We find no evidence…

The COVID-19 pandemic resulted in substantial unfinished learning for U.S. students, but to differing degrees for various subgroups. Students of color, from low-income families, or who attended high-poverty schools experienced greater unfinished learning. In this study, we examined the degree of unfinished learning for students who went into the…

The Anthropocene is a geo-stratigraphic unit of the upper Earth's layers, impacted by human disturbances, but also humankind's historical record, and children's place to live on. It is an unfinished narrative. This study explores how garden and soil-related activities with kindergarten children, guided by well-informed teachers, may have the…

This paper reports on a study concerning the social nature of young students' informal inferential reasoning. Employing inferentialism as a background theory, we examine cognitive and sociocultural aspects of reasoning that arose during group discussions as well as trace relations between those aspects. Following a design experiment approach, we…

This case study investigates how teachers supported below-level readers who made reading comprehension gains in a virtual reading clinic during the COVID-19 pandemic. Data sources included case reports, lesson plans with reflections, and recorded instructional sessions for 10 participants--5 teachers and 5 students. All student participants were…

The current study aimed to understand the perceptions of kindergarten and primary (Grades 1 and 2) educators in Ontario, Canada, regarding their students' developmental and academic skills and their own mental health during the 2021 to 2022 school year. Participants comprised 402 Ontario educators who completed an online survey. Educators…

The study examines students' skills at kindergarten entry and gains in skills across the kindergarten through first-grade period (pre-COVID-19) for predicting literacy, language, math, inhibitory control, and social-adjustment outcomes in the spring of fourth grade, after schools reopened. In a large US school district, longitudinal data were…

Purpose: Previous studies examining the inter-relations between serial and discrete naming with reading have found that the ability to efficiently process multiple items presented in a sequence (indexed by serial naming) is a unique predictor of word- and text-reading fluency. However, conclusions have been tempered by the concurrent nature of the…

With the increasing use of robotics in education, this study examined the influence of educational robotics on K-12 students' creativity and problem-solving skills by using Meta-analysis on 20 typical studies published from 2011 to 2021. Subsequent results exhibited five major points: 1) The overall effect of educational robotics was at 0.821; 2)…
