Student ethnicity is one of the internal factors that influence student learning. Bacteriology is a course that examines prokaryotic unicellular living things and is practiced in laboratories that need to implement projects. The aim of this research is to know the distribution of students based on their ethnicity. The research sample was students…

Although many laboratory experiments are available to illustrate spectrophotometric or fluorometric methods, few of them introduce the use of luminometry to students. Bioluminescence, a subtype of chemiluminescence, is produced when an enzyme-catalyzed chemical reaction gives rise to light emission. Despite the advantages of bioluminescent…

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…

Regulation is a key concept for understanding the dynamics of metabolism in bacteria. This report outlines a simple laboratory experiment aimed at studying a key form of regulation in bacterial metabolism, exemplifying how microbes switch the flux of carbon towards alternative metabolic fates as a function of nutrient availability and according to…

Laboratory course activities often focus on "cookbook style," so their activities have not yet integrated with scientific thinking as an essential aspect. In this research, the laboratory experience of microbial analysis techniques was redesigned using alternative inquiry to involve students in isolating and characterising yeast to make…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

The enzymatic determination of glucose in soft drinks, based on the glucose concentration measurement by means of the coupled reactions of glucose oxidase and peroxidase, has been implemented at the University of Malaga and optimized according to the Biochemistry and Chemistry undergraduate students' results and feedback throughout the last few…

Universities play an important role in society and in providing solutions for its problems. Environmental pollution is one of the most serious problems facing the world today. Thus, universities are increasingly including subjects related to the environment and its conservation both in their educational and research programmes. Generally,…

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…

A laboratory exercise was developed for the study of the effect of three cations (Al, Ca, and Na) on the flocculation and dispersion of soil particles. The exercise was designed for Soil Science undergraduate students in the second-course in the Agricultural Engineering and Environmental Sciences department at the University of Vigo. The students'…

The laboratory practice "Primary culture and directional differentiation of rat bone marrow mesenchymal stem cells (BMSCs)" is part of a required course for sophomore medical students at Tongji university, which has been conducted since 2012. Blended learning has been widely applied in medical courses. Based on a student-centered…

The first case of coronavirus disease 2019 in Colombia was detected on March 6, 2020. Subsequently, schools, colleges, and universities were closed on March 26, which forced a massive migration to virtual education and impacted laboratory-based teaching courses. The teaching of biochemistry requires an experimental component that virtual…

One of the most urgent matters in current medicine is the preservation of antibiotic treatment options due to an increasing threat of antibiotic resistance in pathogenic microorganisms. Therefore, increasing awareness by adapted science education and communication regarding this topic is of the utmost importance. This article shows that an…

Determination of enzymatic activity is a relevant experiment in teaching chemistry and biochemistry to high school and college students. A method for measuring the kinetic parameters of lactose cleavage by the enzyme lactase is described. This enzyme catalyzes the hydrolysis of lactose to galactose and glucose. The kinetic parameters can be…

We have developed an OD3R method that can be applied on Biochemistry learning. This OD3R consists of 5 phases: orientation, decision, do, discuss, and reflect to connect lessons in the class with practice in the laboratory. Implementation of OD3R method was done in 2 universities in Yogyakarta to increase critical thinking skill and practical…
