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…

Science education is crucial for fostering knowledge across academic disciplines. Past efforts to enhance science achievement at the elementary level have explored various instructional strategies. Among these, the Understanding by Design (UbD) model has shown notable potential in improving science achievement outcomes compared to traditional…

This study compares direct instruction to two constructivist approaches, namely experimentation and problem-based learning, in fifth-grade science learning in Hong Kong. Constructivist instructional approaches, contrary to direct instruction, stress on students' active role in constructing knowledge in learning. Experimentation and problem-based…

This study aimed to evaluate the effectiveness of a design thinking teaching and learning model on students' design thinking skills in science class. The study utilised two projects, 'Making a Simple Solar Water Heater' and 'Drawing a 3D Topographic Map of Zhejiang Province,' based on the 5th-grade science curriculum in China, and involved 45…

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 low scientific literacy in students is due to several factors such as lack of motivation, negative attitudes towards teachers, low self-esteem, and lack of confidence in self-ability. This study aims to analyze the effectiveness of the Numbered Head Together (NHT) learning model based on the Growth Mindset of scientific literacy and learning…

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 examined the effectiveness of a literacy-infused science (LIS) intervention on science learning of ELs from rural schools in the U.S.-Mexico border area. The intervention consists of teacher-level virtual professional development (VPD) and virtual mentoring and coaching (VMC), as well as a student-level LIS curriculum. Results from…

Studying nature from the atomic and molecular perspective gives students access to modern scientific paradigms and could improve achievement and motivation towards science learning. A visual and tactile approach to chemistry can form the foundation for a child-friendly but high-level chemistry curriculum and could be a powerful tool to invigorate…

Purpose: Scientific literacy plays an important role in catalyzing science learning in the 21st century. Unfortunately, previous evidence revealed that students' scientific literacy tends to be unsatisfactory. This study investigated the effect of ethnoscience-themed picture books embedded in context-based learning (EthCBL) on students' scientific…

This paper demonstrates the positive impact of learning through ecological fieldwork upon children's ability to write, and to write about science. Specifically we have carried out a relatively large-scale study (involving 379 children aged 9-11 years from 8 primary schools in North East England) comparing intervention classes (involved in…

Teachers often struggle to implement inquiry-based science teaching. To support them, IndagApp--a 3D educational app that offers curriculum-aligned, inquiry-based lesson plans--was designed. The app is rooted in the inquiry phases recommended in best-practices literature, which arguably align with most international standards. This study describes…

This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…

While existing studies have underscored the educational benefits of generating explanatory hypotheses (EHs) in response to unexpected outcomes, empirical research on the underlying mechanisms driving their effectiveness in science learning remains limited. Thus, this study aimed to empirically examine the effectiveness of generating an EH for…

This study aims to conduct a multidimensional analysis of the 2017 Science Curriculum taking the previous three curricula into account. The document analysis technique, which is a qualitative research method, was used. The Science curricula of 2000, 2005, 2013 and 2017 were analyzed in detail for this purpose. The 2017 Science Curriculum, which is…
