Using data from 82 classroom observations conducted in a large urban school district, we explore how kindergartners spend their time in general and across schools serving children from lower and higher income households. Consistent with prior research, we find that kindergartners spend the majority of instructional time on reading and mathematics,…

The current study employed a content analysis approach to analyze and compare argumentation research in K-12 mathematics and science education published on top five academic journals with the highest impact factor from 2010 to 2019. It includes 9 research articles in the field of mathematics education and 77 research articles in the field of…

Numeracy indicates number sense, measurement and geometry but is most often connected to number sense only. Since the domains of geometry and measurement are strongly connected to becoming skilful in science an intervention was carried out to improve children's science skills through measuring and geometry activities and enhance both their…

Several instructional approaches have been advanced for learning programming. However, effective ways of engaging beginners in programming in K-12 are still unclear, especially among low socioeconomic status learners in technology-deprived learning environments. Understanding the learning path of novice programmers will bridge this gap and explain…

The flipped classroom approach has grown in various disciplines; however, only few research studies are conducted in social sciences at K-12 settings. This action research investigated the impact of implementing a flipped classroom approach on students' motivation and learning the content knowledge in a suburban high school introductory psychology…

Abolitionist dreamers have called for justice-oriented teachers to teach K-12 students with marginalized identities through methods of critical and culturally responsive/sustaining pedagogies (Freire, 1970/2018; Gay, 2018; Ladson-Billings, 1995/2021; Paris & Alim, 2014); acts of love, care, hope, and healing (Ginwright, 2016; Love, 2019); and…

The partnership explored in this article offers a high-level view of one university-based research + practice partnership (RPP) with a local informal science institution (ISI) that suggests implications for advancing science education in various contexts. Touching K12 schools, undergraduate coursework, K12 teacher preparation, undergraduate career…

This report summarizes the results of kindergarten through fifth grade students' academic achievement outcomes in mathematics and science following four years of campus-level participation in the Launching Elementary Academic Foundations (LEAF) to STEM program. The LEAF to STEM Program consists of three key components that were adapted for K-5…

In this paper, we present an activity to introduce the idea of public-key cryptography and to make pre-service STEM teachers explore fundamental informatics and mathematical concepts and methods. We follow the Theory of Didactical Situations within the Didactical Engineering methodology (both widely used in mathematics education research) to…

We examined the age of onset, over-time dynamics, and mechanisms underlying science achievement gaps in U.S. elementary and middle schools. To do so, we estimated multilevel growth models that included as predictors children's own general knowledge, reading and mathematics achievement, behavioral self-regulation, sociodemographics, other child-…

This research aimed to investigate the extent to which the interactive international curriculum is included in the "Child's Scientific Activities" issued by the Ministry of Education in Jordan, for the kindergarten stage according to the global criterion (NRC). In order to answer the study questions, an instrument was developed to…

The aim of this study is to determine the problem solving skills and science process skills of six-year-old children who attended kindergarten and whether or not there is a difference in problem solving skills and science process skills of children receiving and not receiving the education with GEMS program. In the study using the experimental…

This is the third whitepaper in the National Comprehensive Center's series on designing curricula for diversity. It provides state and local education leaders recommendations on the use of the Equity and Inclusion Framework for Curriculum Development in the design and adaptation of STEM+CS [science, technology, engineering, mathematics, and…

This paper describes the implementation and student learning outcomes of a nationwide professional development program for lower secondary and upper secondary school teachers to integrate computational thinking into the K-12 curriculum. Computational thinking comprises important concepts and skills that all students should develop to take an…

Physical programming (PP) is defined as the design of interactive physical systems between the real and virtual worlds using a combination of software and hardware. A physical programming platform (PPP) defines a structure that includes hardware and software where such applications can be made. The aim of this study is to introduce the MIDEP…
