Due to the rapid change and development in science and technology, it has come to the fore to educate individuals with 21st-century skills. Scientific argumentation plays important role in developing 21st-century skills. Several studies were conducted on argumentation in science education and laboratory, however, the limited study examined…

Measuring the 3D position at any time of a given object in real-time automatically and well documented to understand a physical phenomenon is essential. Exploring a stereo camera in developing 3D images is very intriguing since a 3D image perception generated by a stereo image may be reprojected back to generate a 3D object position at a specific…

A remote laboratory that measures the enthalpy of vaporization ([delta]"H"[subscript vap]°) and the entropy of vaporization ([delta]"S"[subscript vap]°) of "n"-octane was designed, constructed, and offered to second-year physical chemistry undergraduates at the University of New England (UNE) and Curtin University.…

Virtual reality (VR) lab experiences for organic chemistry were developed at NC State University as an accessibility tool for students who are unable to attend in-person laboratories due to disabilities, attendance challenges such as pregnancy or military deployment, or safety concerns. The resulting first-person VR experiences are immersive and…

Nowadays, novel Biochemistry lab techniques are being introduced at a very fast pace in scientific research. This requires development of new labs for undergraduate Biochemistry courses to equip the students with up-to-date techniques. However, the time limit of Biochemistry labs for undergraduate students represents a major obstacle. This article…

In this paper is presented a pilot study for the investigation of the relevant factors within some experimental works carried out by students, after going through the learning unit "Movement and rest", which can be found in the chapter "Principles and laws in classical mechanics", from the physics curriculum for the ninth grade…

There is a severe shortcoming in science programs in kindergartens in Saudi Arabia. Therefore, this paper presents a conceptual framework for teaching physics concepts to kindergartens to contribute to the consolidation of scientific knowledge by stimulating the skills of inquiry, problem-solving and scientific thinking among children. The…

This article explores results from a 3-year model of laboratory instruction, Project Synapse, that synthesized biology, chemistry, and communication curricula for firstyear science majors at a STEMfocused university. Laboratory biology-chemistry integration was featured at natural intersections where disciplines used similar tools, such as…

In this study, it was aimed to investigate the effects of guided inquiry learning approach-based laboratory applications on the scientific reasoning skills of pre-service science teachers with different cognitive styles. Additionally, the opinions of pre-service science teachers with different cognitive styles about the effects of the application…

Biology laboratory courses with hands-on activities faced many challenges when switched to online instruction during the COVID-19 pandemic. The transition back to in-person instruction presents an opportunity to redesign courses with greater student input. Undergraduates in an [approximately]350-student laboratory course were surveyed about their…

Primarily undergraduate institutions have limited resources to offer required, credit based supplemental instruction for students. Meredith College's Chemistry, Physics, and Geoscience Department revised the laboratory chemistry curriculum to incorporate chemistry concept recitations into the lab course schedule. Activities for the following…

A smartphone-based digital imaging method has been successfully introduced in an undergraduate laboratory class to quantify fluoride ions in water. Students first synthesized the chemosensor (E)-2-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)-N-phenylhydrazine-1-carbothioamide (CT) via an eco-friendly and green microwave-assisted protocol and…

Inquiry-based laboratories were implemented into a General Chemistry Laboratory sequence, and the impact of these exercises on students' experimental design skills was assessed using a four-part assessment developed for this study. This assessment contained a multiple-choice section, a section asking students to explain their reasoning behind a…

Chemical education laboratory practices have not been exempted from the present healthcare crisis. Learning environments have shifted from face-to-face exercises to virtual and video conferencing platforms. Here, we discuss a chemistry for health sciences course which (i) adapted the previous face-to-face laboratory exercises to 100% online using…

For decades, the case has been made for inquiry-based activities that enable teaching and learning of science concepts through the process of doing science. Laboratory courses provide a unique setting with opportunities for students to learn to ask questions, plan and carry out investigations, analyze data, and construct scientific arguments. Yet,…
