In this paper, the multidigit arithmetic-related strategy adaptivity, strategy flexibility and solution accuracy of Danish compulsory school students is examined. Participants, 749 grade three, 731 grade six and 818 grade eight, were drawn from twenty demographically different schools. Drawing on a tri-phase assessment tool, each student completed…

As language programs are endangered in K-16 contexts due to low enrollments, and for budgetary reasons, it is more important than ever to find enduring ways to help promote the study of languages and to make studying languages enjoyable for everyone. For sustainable language education, we need to focus on and promote the true purpose of…

Longitudinal study of associations between family-level emotion socialization and adolescent adjustment is limited. When American children (53.5% girls) were in second grade (N = 213; M[subscript age] = 7.98; data collected 2002-2003), mothers and fathers (79.8% of mothers and 74.2% of fathers were White) reported on their reactions to children's…

We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

Many initiatives have emphasized the importance of challenging students in text using readability formulas. Almost all formulas employ mean word frequency yet long-standing issues abound. Researchers question using a singular mean with a skewed variable like frequency. They also question the degree to which frequency pinpoints complex words,…

Running two separate two-stage randomized trials, we implement and test three variants of a small group instruction intervention aimed at improving mathematics competencies for the 20% lowest achievers in mathematics in grades 2 and 8 in Danish public schools. We calculate immediate impacts on math competencies as well as impacts in the medium…

The share of students attending charter schools has been rising. There is evidence that charter school growth has increased socioeconomic segregation of students between schools. In this paper, we assess whether charter school growth affects how students are organized within nearby traditional public schools (TPS). We use administrative data from…

We study the distributional effects of remote learning. Our approach combines newly collected data on parental preferences with administrative data from Los Angeles. The preference data allow us to account for selection into remote learning while also studying selection patterns and treatment effect heterogeneity. We find a negative average effect…

Montessori is a highly individualized pedagogy that prioritizes following each child's individual interests over standardized test scores. This quasi-experimental study compares groups of Montessori students (treatment groups, N = 535-710) with control groups of non-Montessori students, matched through the simple matching method, which controls…

This study addressed a deficiency in the agricultural literacy of the U.S. population by focusing on the challenges that core subject teachers face when integrating agriculture into their curriculum. Using a phenomenological research approach, this investigation explored the lived experiences of Louisiana teachers who piloted a 4-H STEM…

The paper presents an analysis of elementary grade mathematics teaching in India focusing on mathematical reasoning. Mathematical reasoning is an important tool to make sense of mathematical ideas, which in turn makes mathematics more accessible to learners and promotes social equality. The paper analyzes 112 lessons from Grades 1 to 8 by 21…

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…

A mixed-methods research design was employed to explore the attitudes of typically developing elementary school students (students 8 through 13 years of age; in the United States, third through eighth grade) toward individuals with disabilities. The intervention consisted of person-centred videos that depicted productive, successful people with…

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 COVID-19 pandemic posed a significant problem for K-12 education. To prevent the spread of the virus, the educational community mandated school closures shifting instructional practices from a traditional face-to-face model into a remote instructional model (Bailey et al., 2021; Bawa, 2020; Domina et al., 2021; Onyema et al., 2020; Wyse et…
