An active-learning approach was employed in a project for our chemistry major students on the synthesis of biodiesel (BD) from an Amazon region oil. The project, involving activities in class and in the laboratory, was given during 8 weeks of the spring semester of 2022. The students were asked about their previous contact with the synthesis and…

Enzymes, enzymatic kinetics, and enzyme inhibition are topics covered in undergraduate biochemistry textbooks, having perceptible relevance to everyday life. The experimental use of enzymes involved in basic physiologic processes may be of utmost pedagogic interest because they bring evidence on how a significant number of drugs are used to…

Metabolism is always a challenging topic in biochemistry. In our project, a courseware called "Metabolism Metro" was developed. "Metabolism Metro" is a self-learning tool which aims to facilitate students learning of metabolic pathways in an interactive and easy-to-understand manner. The courseware includes both pre-class and…

The present study investigated if the argument-driven inquiry (ADI) model with embedded explicit-reflective teaching of NOSI improved pre-service science teachers' (PSTs) comprehension of the nature of scientific inquiry (NOSI). The study employed the qualitative experiment method with 16 PSTs. The PSTs working in small groups conducted seven ADI…

In response to the great challenge that the teaching of basic sciences currently entails in the new generations of young people and seeking to awaken the interest of our students in chemistry and its areas of influence, we developed an innovative card game named "Amino-structure" which served as a key tool to implement an active learning…

It is crucial for students with learning disabilities (SLDs) to possess psychological resilience in order to pursue their careers as entrepreneurial individuals. One of the areas where entrepreneurship skills are taught in middle school is in science courses. This shows the importance of teaching psychological resilience in science courses. On the…

To promote scientific literacy in school science, students need to learn key concepts in science, along with the nature of scientific knowledge and how it is generated. Ideally, this learning mirrors authentic scientific inquiry through student engagement in three key epistemic practices: flexibility and creativity, knowledge construction, and…

This communication describes an activity where upper-level chemistry students explore the determinability of rate constant values without concentration dependences (k[subscript true]) related to a solvent-ligand exchange in a transition metal carbonyl complex. By performing a series of multivariable linear regression (MVLR) analyses of…

Surface chemistry is a challenging realm for most students because of its abstract nature and numerous associated mathematical equations. Herein we report a set of dedicated sequential inquiry-based learning (IBL) activities enriched with virtual laboratory learning and hands-on instructions. The activities were intended to help students grasp…

It might sound to some like an impossible target to give children 22 hours of scientific enquiry by Christmas, but the current COVID-19 pandemic has already demonstrated its capacity to make the impossible happen and to upturn so many of the assumptions that have shaped the way people teach and learn. Children can reach 22 hours of enquiry if…

Bacteria, viruses, and other invisible creatures are, in brief, microorganisms. Especially with the onset of the COVID-19 pandemic, the features of microorganisms, their density, and relevant precautions have grown in importance. Knowing the density of microorganisms at school will cause our cleaning habits to change. In this study, efforts were…

This study was carried out as collaborative action research aims to develop inquiry-based science activities in early childhood education. One volunteer teacher (T2) who desired to develop inquiry-based science activities, 14 of her students and the researcher participated in action research. The action phase consisted of six action cycles that…

Stable isotopes in natural materials provide a powerful way to study energy flow in many systems and are widely used in fields such as archaeology, ecology, forensics, geochemistry, geology, oceanography, palaeoecology and palaeoclimatology. Based on the manner in which stable isotopes fractionate in natural systems, they allow scientists to…

In scientific practices, students are frequently asked to conduct investigations to produce data that will serve as the basis for evidence that meets the goals of an investigation. But however, assisting in the formulation and implementation of students' investigations is often a difficult task for many teachers because authentic investigations…

Kinesthetic experiences in the classroom seek to engage students by muscle movement, touch, or some form of physical activity. In this article, I describe an active learning session wherein students develop a qualitative understanding of center of mass and support forces using their sense of touch. The set of activities detailed here is based on a…
