This article details the outcome of a joint reflective approach undertaken by the authors to identify common difficulties experienced by 2nd-year undergraduate Biochemistry students in laboratory classes. Difficulties experienced in laboratories can affect the development of hand skills, an understanding of how to correctly operate laboratory…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

During COVID-19 remote instruction, instructors were tasked with providing students with authentic laboratory experiences in an out-of-classroom environment. One solution developed for our introductory general chemistry laboratory involved students critiquing readily available technique videos to distinguish between correct and incorrect…

Fully online courses and degree programs are popular with students. These courses should provide the rigor and value of traditional learning in a face-to-face classroom to ensure mastery of concepts and learning objectives. This research expands previous work to investigate the effectiveness of online laboratory exercises in enhancing student…

Isoenzymes are variant forms of the same enzyme activity that exhibits different tissue distribution. When cells are damaged, intracellular content leaks into the blood stream, making them potential biochemical markers. Undergraduate health sciences students are expected to interpret laboratory findings of serum levels of biochemical markers and…

The advantage of VLs lies in their capacity for simulating real-world lab experiences within a fully immersive digital environment, yet the uptake in rural schools in developing countries remains low. To understand this paradox, this study explores the perceptions of seven secondary school science teachers in a rural district in South Africa.…

Prior to the challenges imposed by the COVID-19 pandemic, anatomy practical sessions at Trinity College Dublin involved eight to 10 students per donor station, rotating between digital learning, anatomical models/osteology, and dissection activities for three hours weekly. To maintain cadaveric participation in the anatomy laboratory while…

Chemistry laboratory experiences provide students the opportunity to engage all three domains of learning: psychomotor, cognitive and affective. However, they are often stressful environments where students are expected to quickly learn new laboratory techniques, and collect data in a short amount of time. In principle, providing additional…

The COVID-19 pandemic has constituted a sudden educational transformation around the world. It has disrupted instructors, including physics educators, forcing them to adjust to remote teaching. The hands-on laboratory, one of the components of physics instruction, has also had to rapidly go online in all branches of this science, including nuclear…

The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

Course-based undergraduate research experiences (CUREs) have grown in popularity, particularly within introductory biology courses, to provide more students with authentic research experiences. CUREs have been shown to have many of the same positive effects as conventional research experiences; however, most assessments of CUREs lack an…

Although physical hands-on laboratory experiments are commonly used in schools, virtual laboratory environments are also being used in science classrooms. Their possibilities and impact on students' achievement, conceptual understanding, and inquiry skills have been investigated by other researchers. Yet, it is difficult to find studies about the…

Virtual laboratories have started to be the leading alternative teaching tools during the COVID-19 pandemic process. The "Acid-Base" subject is among those that form the foundations of biochemistry. Students can learn the "Acid-Base" subject in a secure environment, with remote access through the use of virtual laboratory…

This study was conducted to determine the effectiveness of virtual laboratory based on semi second life (s-SL) on higher order thinking skills of general senior secondary school in chemistry learning process. The research design was adopted posttest only design approach to a quasi-experimental. This study was conducted in the one of public general…

Virtual experiments offer opportunities for students to engage in the scientific process and observe scientific phenomena. However, virtual experiments are not always effective for learning. The current study examined how two small manipulations might support better learning from virtual experiments and the extent to which this varied across…
