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…

Background: The question of the efficiency of withholding answers and the physical manipulation of material in science education has become the target of a large number of researchers (proponents of the Cognitive Load Theory) in recent years. However, no research has been found examining the contribution of these elements of teaching to the…

The purpose of this study was to determine the factors that influence the self-efficacy of undergraduate kindergarten teachers and kindergarten teachers to teach science in kindergarten. The research questions were: (1) To what extent, if at all, does the research participants' self-efficacy to teach science change following their academic…

Through a meta-analysis, this study examines how effective particulate nature of matter (PNM)-based intervention studies are at improving academic performance. Well-known databases (e.g., ERIC, Springer Link, Taylor & Francis, and ScienceDirect) were used to look for the PNM-based intervention studies via specific keyword patterns. Also, a…

In the last 30 years, 4 distinct theoretical approaches have been described for early childhood science education. The approaches are, empiricist, Piagetian, socio-cognitive and socio-cultural. Drawing on the differences among these approaches regarding the theoretical framework adopted in teaching, the role that is assigned to the teacher during…

The instructional congruence framework has been used to enhance congruence between students' non-dominant backgrounds and science instruction in upper grades. The purpose of this paper is to propose and model the use of the framework to address two key areas of concern in the field of early childhood teacher education: family engagement and the…

Recent reforms in K-12 science education call for curricular materials that are designed to be "coherent for students." This form of coherence arises when the classroom community sees their science work as addressing their questions and problems. In enactment, the teacher sometimes has to improvise from the planned trajectory of the…

This is a review of the findings of a study investigating the impact of a project-based elementary science curriculum on academic achievement and aspects of social and emotional learning. The study by Michigan State and University of Michigan researchers found that use of the project-based learning (PBL) program, Multiple Literacies in…

Inquiry-based science education has become one of the most effective methodologies to learn science; however, proposals in preschool are scarce. Different factors are responsible for this situation, such as the low self-confidence of teachers to teach science and the belief that young children are unable to develop certain reasoning skills. This…

The study aimed to investigate preschool children's learning needs related to science and their teachers' science activity practices. A basic qualitative research design was applied. Interviews were conducted with 15 preschool teachers and 48 children living in Ankara and subjected to content analysis. It was found that teachers mostly carried out…

This study aimed to unveil pre-service primary school teachers' (PPSTs) technological pedagogical content knowledge (TPACK) regarding the unit "Let's Recognize the Force" suggested by grade 3 science curriculum. Through a single-case (holistic) design of case study method, 43 PPSTs voluntarily participated in the study. To collect data,…

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…

Schools across the United States are seeing an increase in culturally and linguistically diverse students. While there is recognition of the need for culturally and linguistically responsive teaching practices in K-12 settings, many teachers encounter challenges in effectively implementing these practices, particularly in science classrooms. There…

A self-avoiding walk (SAW) is a sequence of moves on a grid that does not visit the same point more than once. SAWs are used to study how networks form, including social networks, biological networks and computer networks, and have provided inspiration to scientists, artists and designers. Here we describe a collaborative project which aims to…

This classroom-based study aims to contribute knowledge about children's opportunities to make use of drawing to make meaning in science. Employing a social semiotic approach to drawing, we examine what ways of representing science content that are: (1) made available by the teacher; and (2) adopted in children's drawings. We analysed observation…
