This study reports on the theoretical- and empirical-based design and evaluation of cell membrane biology learning activities within the Model of Educational Reconstruction and experiential realism. First, we designed analogy-based learning activities by considering students' and scientists' conceptions as described in the literature. Secondly, we…

Although Ohm's law contains various possibilities in teaching and learning scientific inquiry, it is rare for students to experience an authentic inquiry. Thus, we designed an open-ended in-depth inquiry about Ohm's law and made students conduct it. To do this, we developed a laboratory activity for students following a standard method of Ohm's…

This article describes two sets of experiments designed to enhance the understanding of colloidal systems. These experiments were designed as a part of the theme "Colloids: Where Science Meets Engineering" taught in the Department of Chemical Engineering and additionally offered to physics, chemistry, and materials science departments as…

Computer-simulated experiments have been gaining popularity over hands-on experiments in science education, given the availability of technology and the trend of distance learning. Past studies have focused primarily on comparing the learning outcomes and user experiences of the two experiment modes. In this study, we used an eye tracker to…

Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…

Many studies have reported various interventions to increase critical thinking, but very few studies have examined the impact of learning in classrooms and laboratories. This study aimed to find a learning pattern (practice to theory or theory to practice) in improving students' critical thinking skills (CTs). Pre and posttest nonequivalent group…

This paper presents an innovative teaching approach that integrates photoelectric technology with analytical chemistry instruction through inquiry-based learning (IBL), using cerium as a selected analyte. With the advancement of science and technology, a strong foundation of basic knowledge and methodologies is crucial in analytical chemistry…

The implementation of video modeling examples of mathematical hands-on experimentation may provide students with authentic and, at the same time, not too cognitively overwhelming experiences. However, the effectiveness of video modeling examples can be influenced by different characteristics of the observed models. On the one hand, based on the…

This paper presents an analysis of cognitive skill levels expressed in high school students' performance using laboratory simulations. We address lower-order cognitive skills (LOCS) and higher-order cognitive skills (HOCS) situations in a virtual simulation activity, in order to identify and underly further discussions about students' reasoning…

This paper uses evidence-centered assessment design (ECD) to structure and analyze a laboratory activity where students collect and represent titration curve data to determine acid strength in terms of molarity and dissociation constant. Following principles of multidimensional learning, the activity prompts students to demonstrate knowledge of…

The aim of this study was to develop a science experimental guidebook for the mainstreamed students with learning disabilities and investigate its effect on their conceptual understanding of physical events. Through case study research methodology, the sample of the study consisted of 12 mainstreamed students with learning disabilities. To collect…

In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are that students will never have the opportunity to work with one. A hydrogen electrode should be a device readily available at the…

Active learning is widely recognized as superior to traditional passive, lecture-based techniques for fostering learning in STEM courses. Interactive, hands-on learning where students interact with their peers and physical systems is an effective type of active learning. As the need for scientists and engineers continues to grow, understanding and…

Renewable energy is a trending topic due to its importance in today's society especially because of global warming. Because of its importance, this topic should be discussed at schools in an inclusive education environment. Experimental work is a very good activity to provide students effective conceptual discussions, but it is necessary to…

The COVID-19 outbreak has had a significant impact on higher education worldwide. In-person courses had to be quickly transited to online, including lab courses embedded with Course-based Undergraduate Research Experiences (CUREs). In response to this challenge, we successfully converted a fully in-person biochemistry lab that integrated with a…
