As an introduction to sound and vibration, the authors wanted their first-grade students to plan and conduct their own investigations. In this article, the authors share a series of investigations to help students explore the relationship between sound and vibration. By planning, creating, testing, adapting, and reflecting on the outcomes of the…

It is a challenge to carry out science lessons with experiments both in the conditions that emerged with the COVID-19 pandemic and in schools where there is a shortage of laboratories and materials. This study aims to examine the proficiency and opinions of pre-service primary teachers (PPTs) pertaining to performing hands-on science experiments…

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…

Virtual experiments are widely used in the field of education for their low cost, strong interaction, hyperspace and safety advantages. While some researchers have analysed the impact of virtual technologies such as AR or VR on teaching effectiveness, few researchers have comprehensively explored the impact of virtual experiments on students'…

In science education, the improvement in students' ability to construct arguments at the primary school level has been reported. Although these studies have identified difficulties in arguments written by primary school students, they do not indicate areas that require improvement in teaching methods. This study aims to explore the possibility of…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Planning and conducting experiments require the application of the control of variables strategy (CVS). Research indicates that older children can learn the CVS by engaging in guided-inquiry activities. It has not been studied yet whether this is also the case for children as young as 6- to 7-years. 145 children aged 6-7 years participated in a…

Cognitive style differences, also known as 'empathizing' and 'systemizing' have been argued as one reason that may explain differences in children's motivation to learn science. Researchers claim that people with a 'systemizing' cognitive style are likelier to engage in science than those with an 'empathizing' cognitive style. As such, they…

Purpose: A growing trend in instructional improvement efforts is the use of formative assessment informed by research-based developmental trajectories of how students gain deeper understanding of subject matter content over time. This article reports the findings of a large-scale experimental study of an innovative mathematics professional…
