Course-based undergraduate research experiences (CUREs) are increasingly popular, but less often implemented in core laboratory courses due to the strict learning objectives necessary for follow-on courses. A curricular core intermediate-level experimental biosciences laboratory course was implemented, which paired competency-based assignments…

This study has proposed a simple method to show the convective heat transfer. The object in this study is an air conditioner (AC) as a simple case of convection. In addition, AC is also easy to find in the class because most classrooms in Indonesia installed AC. Usually, a visualization needs special software (i.e. MatLab or others) and good…

The laboratory course in organic chemistry for preservice chemistry teachers has been designed anew. For the course, only 2 weeks (8 h a day) are available. Therefore, we wanted to use this time effectively, which led to the following main goals: the students should achieve practical skills, understand the practical procedures they had to conduct,…

Enzymes are widely applied in different industries, like pharmaceutical, food, biofuel, and waste valorization. However, the enzyme operating conditions are very limited. So, in most industrial processes, enzymes are not efficient, due to the use of harsh conditions, like organic solvents, extreme pH, and temperature. Immobilization arises as a…

This study is the result of a quantitative analysis of the previous paper reporting on four cases in which an LED is turned on by charge transfer occurring during the electrostatic induction process in a conductor connected to the LED. We were able to measure the charge transfer by using charge sensors and analyze experimental results by applying…

In science learning, the experiment is an essential activity to facilitate students to discover and develop knowledge as well as to enhance scientific process skills and self-confidence. This study aims to create a simple experimental apparatus related to the principle of fluid continuity that can be made and conducted by the teacher and student…

Polymerization reaction media can have a profound effect on the physical properties of the resultant polymer. This phenomenon is showcased in a new experiment for the organic chemistry and polymer science teaching laboratories wherein the radical copolymerization of biobased [beta]-myrcene and dibutyl itaconate is performed using a nonhazardous…

Smartphones, coupled with small mobile sensors, make it possible to work with near-infrared (NIR) spectroscopy in science classrooms. NIR spectroscopy has become a standard analytical technology in various industries. These new devices enable students to create their own data in real time. This article presents an inquiry-based teaching unit, in…

Contribution: Two toolsets for the remote teaching of radio communication laboratory classes: 1) online simulators for individual work of students and 2) a remote access system to laboratory workstations for group work. Initial assumptions and method of implementation of both tools are presented. Background: The COVID-19 pandemic has forced a…

Today, immersive technologies like Virtual Reality (VR) are regarded as disruptive tools in many domains, including education. While the body of literature in the field is growing, studies that present contrasting findings are not uncommon. In fact, although there is evidence of the benefits brought by VR in the educational processes, in some…

Teacher evaluation and teachers' professional learning are too often confined to separate areas of research and professional practice. Rather than approach evaluation and enquiry as distinct or irreconcilable, this paper applies the ideas of Stenhouse to explore new possibilities for the reappropriation of mandated appraisal in ways that support…

In today's knowledge-based and rapidly changing society, developing students' critical thinking skills in instruction is a vital concern in almost all science curricula. To acquire meaningful learning, learners need to develop skills in choosing suitable information, gauging the integrity of information, and crafting sound decisions. With this,…

The present two studies investigated whether students' development of epistemic beliefs about the educational sciences (study A; N = 152) and linguistics (study B; N = 150) can be affected by authentic learning activities in an out-of-school lab (OSL). OSLs aim to engage students in authentic activities that attempt to simulate the ways how…

Human dissection is an ancient pedagogical method that is still relevant in modern anatomy curricula. The body procurement process for dissection purposes has undergone significant evolution from the medieval era until now, whereby body donation has become the main source for human bodies in medical education. The appreciation ceremony for body…

This article aims to simplify and facilitate the process of practical teaching of enzyme kinetics by utilizing minimal teaching laboratory requirements. Simultaneously, it ensures that students comprehend the enzyme kinetics experiment effectively. The focus is on teaching students how to estimate the maximum velocity (Vmax) and Michaelis constant…
