Understanding experimental design (e.g. control of variable strategy or CVS) is foundational for scientific reasoning. Previous research has demonstrated that demonstrations with cognitive conflict (e.g. asking students to evaluate and explain different experimental designs) are effective in promoting children's scientific reasoning, however, the…

Picture book reading is essential in the early stages of learning and development. The current study aimed to incorporate picture books to improve first graders' scientific thinking, including scientific reasoning and creativity. The study adopted a quasi-experimental research design. There were 24 students in the experimental group and 23 in the…

While helping students develop informed views about nature of scientific inquiry (VNOSI) has been emphasised in science education, little is known regarding students' current VNOSI at a certain grade level and whether there was evidence of higher attainment of VNOSI in students in higher grades as compared to lower grades? The purpose of this…

The inclusion of engineering in the Next Generation Science Standards (NGSS) as a key component of K-12 science learning has provided both opportunities and challenges for elementary teachers. One challenge is integrating the design thinking processes that undergird engineering with core science concepts and current issues facing scientists and…

This study was conducted to investigate the effects of learning trajectories-based coding (LTs) and LTs-based program on preschoolers' length, area, volume, and angle measurement skills. A quasi-experimental research design was utilized with a quantitative approach. The study's participants were 47 children between the ages of 55-71 months who…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

The inclusion of Computational Thinking (CT) in the classroom along with the promotion of positive attitudes in early ages towards technology have great relevance in the current educational paradigm. This study analyses whether CT instruction may improve pupils' attitudes towards technology, and also considers whether instructional approaches and…

The NGSS Early Implementers Initiative was created to help eight California school districts and two charter management organizations, supported by WestEd's K-12 Alliance, implement the Next Generation Science Standards (NGSS). Many educational initiatives are funded for only a couple of years. This unique initiative spanned an extraordinary six…

Programmed control systems are ubiquitous in the present-day world. In current educational practice, however, these systems are hardly being addressed, and little is known about children's spontaneous understandings about such systems. Therefore, we explored pupils' understandings prior to instruction in three concrete settings: a car park, an…

The purpose of this explanatory sequential mixed-methods study was to assess the impact of the STEM integration program on third through fifth grade students' achievement scores in mathematics and science in an urban northeastern Georgia school district. In Phase 1, a quantitative research design was used to examine and compare student achievement…

This study aimed to examine how instruction of geography subjects in primary school third-grade Life Studies course with several methods affects students' attitudes toward this course and their spatial perception skills. To that end, the study was designed with exploratory sequential mixed methods approach. Two third-grade classes at a public…

Children's preschool years are crucial for the development of computational thinking (CT) skills. However, debate continues regarding whether CT should be developed through plugged-in or unplugged activities. This study investigated the similarities and differences between plugged-in and unplugged activities with similar learning content and…

Argumentation, a key scientific practice presented in the "Framework for K-12 Science Education," requires students to construct and critique arguments, but timely evaluation of arguments in large-scale classrooms is challenging. Recent work has shown the potential of automated scoring systems for open response assessments, leveraging…

This study aims to reconstruct Grade 11 students' misconceptions about force through the Conceptual Change Model (CCM) making use of Predict, Discuss, Explain, Observe, Discuss, Explore, Explain (PDEODEE) tasks. This study was conducted using a mixedmethod approach. The participants in this study were 65 students (33 students in the experiment…

This randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers' mathematics and science instruction, and children's mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of…
