Due to the COVID-19 pandemic, in-person undergraduate chemistry laboratories at North Carolina State University were not available to students during the 2020-2021 academic year and were replaced with online laboratories. With the return to in-person laboratories in the fall semester of 2021, there was widespread concern among the faculty that…

Administration and funding can cause Engineering/Technology Education (ETE) programs to thrive or die. To administrators, the production/prototyping equipment and laboratory setting are often viewed as the features that set ETE apart from other school subjects. A lab is a unique gift as well as a responsibility. If an administrator can see that…

Introductory physics labs often focus on a series of common experiments intending to teach the student the measurement side of physics. While these experiments have the potential to be quite instructive, we observed that our students often consider them to be boring and monotonous, which often leads to them being uninstructive. To combat this, we…

Digital and innovation competencies are nowadays highly required for students and faculty members in higher education institutions. We therefore need environments that incubate innovative learning scenarios to develop these competencies. We conducted a design-based research with the dual objective to develop learning labs in four universities and…

The determination of the speed of sound in air is a classical experiment, usually performed with a resonance tube apparatus. The measured value can be checked against Eq. (1), which describes the temperature dependence of the speed of sound in dry air. A modern implementation of this speed of sound investigation uses an Arduino Uno microcontroller…

The COVID-19 pandemic forced the adoption of online laboratories. The present article discusses the virtual laboratories used by students. The questions posed by students provided targeted teaching opportunities.

The scientific community continues to give conflicting impressions about the contribution of laboratory activities to science learning and yet ignores the views of students who are the focus of learning. In this paper, we reviewed postsecondary school students' experiences in the science laboratories. Students were most concerned about the impact…

As a result of the COVID-19 pandemic, it is crucial for an introductory course in biochemistry to move from in-person instruction to total remote learning. There are four transferable skills in the course: problem-solving, laboratory psychomotor skills, data analysis and interpretation skills, and presentation skills. Since all lab buildings were…

Multistep synthesis is a key capstone experience in organic laboratory instruction. Here, a four-step synthesis of avobenzone, an active component in sunscreens, has been developed that can be completed in two 4 h laboratory periods. This synthesis incorporates green principles and includes an aldol condensation, electrophilic addition of bromine…

While debate about the use of--and alternatives to--human cadaveric dissection in medical training is robust, little attention has been paid to questions about timing. This study explores the perspectives of medical students and recent graduates with regard to two key questions: when in the degree program do students prefer dissection…

Single slit diffraction and the thermal expansion of materials are common components of an undergraduate physics course, though these topics are often taught independently in both lectures and laboratory based courses. Higher levels of cognitive domains can be achieved by building on these established topics and combining them into a single…

During the spring of 2020, teaching laboratories worldwide were closed, and teachers quickly prepared online substitute activities. This study investigates the students' experience of the substitution of laboratory teaching with theoretical activities in an instrumental analytical chemistry course in the students' second year of study. Twelve…

Learning and learning goals in undergraduate chemistry laboratory have been a popular research topic for the past three decades due to calls for curriculum reform, cost justification, and overall efficacy of necessary skill development. While much work has been done to assess curricular interventions on students' learning and attitudes towards…

This study was a prospective, randomized controlled trial. The study sample consisted of 105 healthy neonates who conformed to the case selection criteria. Neonates were randomly assigned to the following groups: swaddling (S), maternal holding (MH), and controls (C). The study data were obtained using an information form and the Neonatal Infant…

This study aims at creating an integrated design of a building material laboratory for Teacher Education Institutes (TEIs) in higher education of vocational and academic programs to support the effective and efficient learning processes. Development of a building materials laboratory design in the form of a 2-story floor plan with a capacity of 20…
