Despite the growing number of published studies on student learning in the laboratory, there is a critical need to improve methodological rigor. Resonating with discussions on research methods, this paper outlines the importance of theory-informed research questions, the minimization of researcher and participant biases, and the use of triangulation and iteration in data collection to establish rigor. An illustrative case is presented within the context of a large interdisciplinary research project aimed at improving laboratory learning at the university level. The project incorporates two research avenues: one focusing on student and faculty perspectives, and the other on a comprehensive assessment of multidimensional learning in the laboratory. The project employs a mixed methods paradigm and is grounded in a conceptual framework that conceptualizes laboratory work as epistemic practice, requiring a holistic analysis of student learning. The article concludes by discussing the results and implications of the project’s findings, which are synthesized to highlight aspects of establishing methodological rigor. The overarching goal is to develop a comprehensive assessment instrument that captures the complexity and richness of the laboratory learning environment. The findings from this research are expected to contribute to the advancement of laboratory education research by providing a model for methodological rigor that can be applied across various scientific and interdisciplinary contexts.

Herein, we present the implementation of a low-cost web-based information system tailored to manage a university department chemical warehouse. The system provides a centralized platform for cataloging, tracking, and managing chemical inventory data, while also facilitating purchasing and various administrative tasks associated with laboratory operations. The system has been developed within the Campusnet platform and has the following functionalities: (i) an efficient way for cataloging the extensive array of products available in the warehouse; (ii) an intuitive web interface with a device-responsive layout to facilitate browsing and purchasing of products by students, researchers, and technical staff; (iii) an inventory transaction recording system to simplify the attribution of costs; (iv) a simple procedure to streamline the process of joint purchases; and (v) a low deployment cost and ease of maintenance. Key design considerations, including regulatory compliance and safety, are also presented. Full article

Authentic hands-on learning experiences are paramount for applying content and practices in science, technology, engineering, and mathematics (STEM) and career and technical (CTE) education.

Authentic hands-on learning experiences are paramount for applying content and practices in science, technology, engineering, and mathematics (STEM) and career and technical (CTE) education. Such learning experiences are foundational for preparing P-12 students for future post-secondary and workplace opportunities. However, valuable hands-on learning opportunities often involve some level of potential safety hazards and resulting health and safety risks. While progress has been made in some aspects of STEM education and CTE safety, numerous safety issues and barriers remain. This article provides a detailed overview of some of the most pertinent health and safety issues from the literature and recent studies (e.g., overcrowding and occupancy load). Moreover, this article provides important information for policy makers, state departments of education, teacher preparation programs, school systems, school administrators, curriculum directors, educators, and other stakeholders to make data-informed decisions to improve safety in P-12 STEM education and CTE programs.

The rapid evolution of robotics across various sectors, including healthcare, manufacturing, and domestic applications, has underscored a significant workforce skills gap. The shortage of qualified professionals in the labor market has had adverse effects on production capacities. Therefore, the significance of education and training for cultivating a skilled workforce cannot be overstated. This research work presents the development of a pedagogical approach centered on laboratory infrastructure designed specifically with multidisciplinary technologies and strategic human–machine interaction protocols to enhance learning in industrial robotics courses. Progressive competencies in laboratory protocols are developed, focusing on programming and simulating real-world industrial robotics tasks, to bridge the gap between theoretical education and practical industrial applications for higher education students. The proposed infrastructure includes a user-configurable maze comprising different colored elements, defining starting points, endpoints, obstacles, and varying track sections. These elements foster a dynamic and unpredictable learning environment. The infrastructure is fabricated using Computer Numerical Control (CNC) machining and 3D printing techniques. A collaborative robot, the Universal Robots UR3e, is used to navigate the maze and solve the track with advanced computer vision and human–machine communication. The amalgamation of practical experience and collaborative robotics furnishes students with hands-on experience, equipping them with the requisite skills for effective programming and manipulation of robotic devices. Empowering human–machine interaction and human–robot collaboration assists in addressing the industry’s demand for skilled labor in operating collaborative robotic manipulators. Full article

Textile chemistry and textile processing laboratories are essential environments for textile product research and development, but they also pose hazards that require rigorous precautions. Among the most common risks is handling chemicals used in the textile industry, such as dyes, solvents, and finishing chemicals, which can be contaminants, corrosive, and flammable, presenting risks of poisoning and fire. Textile processing laboratories also require proper ventilation, as a lack of appropriate ventilation in these environments can accumulate toxic vapors in the air. The most relevant risks and hazards of using textile chemistry laboratories include using equipment such as dyeing autoclaves under pressure and high temperature; drying ovens like furnaces/lab stenters; cylinders of squeezing, calenders, and others, capable of causing severe accidents. These laboratories also generate or handle solid waste and effluents containing, heavy metals to pathogens (e.g., from industrial sludge). It is essential to adopt rigorous safety measures in textile chemistry laboratories, including using personal protective equipment (PPE), proper training of workers, effective ventilation systems, and safe waste disposal protocols. Good laboratory work practices not only reduce risk but also promote better research; more accurate results; and better data. Therefore, this study aimed to map the risks and hazards of textile processing laboratories with a view to accident prevention and formalizing a protocol for good practices. Full article
