It is urgent to ensure that science, technology, engineering, and mathematics (STEM) education meets the needs of our nation's increasingly diverse student population. This study examined whether a second-grade science program, Scientific Explorers, supported educational equity in STEM achievement for diverse student populations. Sociodemographic…

A student's socioeconomic status (SES) has a significant relation to their academic achievement. Much of this work has explored this in math and reading, but less is known about how SES relates to science achievement, particularly in the early grades. Using quantile regression with nationally representative data, we explored this relation in…

Young children, who are exposed to Latin script letters, experience difficulties in distinguishing between the reversible letters b and d and may therefore transform b into d (and vice versa). When children begin to write, in cultures with left-to-right writing/reading systems, they also often turn Arabic digits in the direction of…

Using a verbal protocol, this study investigated how 38 second-grade students identify, describe, and interpret five types of commonly used visual graphics in science texts (i.e., cut-away diagrams, maps, captioned photographs, flow diagrams, and hybrids). Additionally, we explored the challenges students encountered when interpreting these…

There are arguably advantages to adopting a cross-curricular approach to planning, teaching and learning. This approach often works well for incorporating scientific skills and the wider perspectives of geography, technology and maths. It can help children to develop and consolidate their understanding through practical application and gives them…

This article explores the integration of the art studio framework developed by Harvard University's Project Zero into science education and investigates its influence on the academic achievements of third-grade students. This study involved a cohort of 140 third-grade students from a primary school in Iran, 70 of whom were students assigned to an…

In the early years of school, pupils have a very positive approach towards any new topic. Very often, the first contact with mathematics in the Italian school risks giving a limited and somehow negative impression, generating long-lasting effects. In this paper, we report on a series of experiences carried out in a second-year class of a primary…

The purpose of this study is to illustrate the use of functional data analysis (FDA) as a general methodology for analyzing person response functions (PRFs). Applications of FDA to psychometrics have included the estimation of item response functions and latent distributions, as well as differential item functioning. Although FDA has been…

Throughout the country, there are many bodies of fresh water affected by algal blooms. By focusing on a water source near their school, students can become scientists, too. Situating science content in real and meaningful learning experiences encourages students to be invested in their own learning, construct deeper understandings, and apply those…

Several researchers and scientific institutions argue that evolution should be explored from the first school years. However, few studies have analysed primary school students' understanding of evolutionary processes or evaluated the impact of educational activities on such knowledge. The available data: (1) suggest that primary school students…

The purpose of this research was to find out if parental involvement in the study school helped to increase student academic achievement. Previous studies have shown that when parents are involved in the educational process of children, parents can expect a gain in academic achievement. This mixed method study examined the relationship between…

In this paper, we draw on the ontology and epistemology of the local Kasena ethnic group in Northern Ghana to explore Early Childhood Environmental Education. The study, taking place in Boania Primary School, drew on the concept of two-eyed seeing, where both western and Indigenous epistemologies and ontologies were taught. In this way, Indigenous…

Common objects are made of materials that have obvious physical features which, although readily observable, may be overlooked by children. Helping young children to notice characteristic features -- scientifically referred to as properties -- equips them to discern common and distinct (diagnostic) features. Once children begin to recognise…

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…

The objectives of the research were: 1) to develop the lesson plans for "Weight and Measurement" of Mathematics by using Problem-Based Learning on TPACK MODEL based on the efficiency of the process and the overall result (E1/E2) at the established criteria of 75/75; 2) to compare the students' learning achievement in "Weight and…
