The goal of undergraduate chemistry laboratories is to allow students to learn about chemical systems and key laboratory skills. They should then apply this knowledge to solve problems and connect macroscopic observations in the laboratory with those occurring at the submicroscopic level. Unfortunately, these needs are not met through traditional…

For the past several decades, high-enrollment undergraduate chemistry laboratory experiences have favored traditional approaches involving disparate daily experiments with optimized protocols provided to students. This model often results in poor learning outcomes and low student engagement, and it lacks any attention to scientific inquiry. Here,…

Existing accounts of student thinking about mechanical wave propagation and superposition emphasize that students sometimes treat wave pulses as objects, saying, for example, that pulses bounce off of one another when they meet. In this paper, we present a context in which students explicitly reason about pulses as not-objects, instead describing…

Guiding students to become practicing scientists entails teaching them the specialized ways of collaborating, writing, and thinking that these professionals utilize every day. Laboratory experiences provide unique opportunities for student-centered curricular activities that mimic these skills. The biodiesel laboratory experience described here…

Engineers are vital to the way we live, our everyday experiences and activities, but despite this engineering receives little focus in the primary classroom. Interest in STEM (science, technology, engineering and mathematics) wanes as children reach the end of primary school. However, providing positive experiences can keep the doors open for…

Numerous challenges occur in education field require effective solutions to encounter. The aim of this research was to investigate the effectiveness of guided inquiry model with starter experiment approach in teaching science process skill. This quasi-experimental research employed non-equivalent control group design. A total of 64 students of X…

Being immersed in the processes of research can develop undergraduate students' science identities and support their persistence in pursuing science careers. However, it can be difficult for students to find opportunities for engaging in authentic scientific research. The professional staff and scientific objects in natural history museums provide…

Building on rich training literature, we examined which skills constituting the control-of-variables strategy (CVS) benefit from a comprehensive training, and which develop similarly during content-focused inquiry at ages 10-12. In addition, we examined whether prior knowledge, reasoning abilities, and reading comprehension explain variation in…

In this study, the primary goal was to enhance the knowledge and awareness of 4th-grade primary school students regarding global pandemic diseases and methods of safeguarding against worldwide epidemic diseases which are socio-scientific issues. To achieve this goal, two activity modules tailored for 4th-grade students were created. These…

Although laboratory work is considered a significant factor in helping students develop their science process skills and cultivate alternative knowledge construction, there are still gaps in the selection, integration, and implementation of the basic elements in physics laboratories. In this study, three modified guided discovery and conventional…

Learning for sustainability (LfS) encompasses holistic, interdisciplinary experiences that equip learners with essential sustainability competences. The 2018 Council Recommendation on key competences for lifelong learning emphasises improving, among others, basic skills (such as literacy and numeracy), competences in STEM, and digital competences,…

For two decades, the state role in educating children before kindergarten has been growing, and it is accelerating. Enrollment in state-funded preschool today far exceeds that in federal Head Start, and states are the dominant provider at age 4, serving about half of all four-year-olds who attend any preschool program. New universal preschool…

Students need procedural understanding--that is, knowledge of the procedures that scientists use to establish scientific evidence (also known as "concepts of evidence"), to successfully perform scientific investigations, and to evaluate public and scientific claims. However, concepts of evidence are seldom explicitly targeted in routine…

The aim of this study is to investigate the effects of science, technology, mathematics, engineering (STEM) applications and STEM based teaching on 8th grade students' environmental attitudes, scientific creativity, problem solving skills and science achievement and to get students' opinions about STEM practices. Two groups were used in the…

This article describes a three-dimensional 5E (Engagement, Exploration, Explanation, Elaboration, Evaluation) lesson that investigates 3-LS4-1: Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived. A phenomena-based approach was used to engage third graders in the story of Maya, who…
