Chemical reasoning takes many forms. The focus in this paper is on a reasoning process that facilitates using experimental evidence to make connections between macroscopic and submicroscopic domains, which we will refer to as "creating representation." It is a particular type of reasoning that has played a critical role in chemistry,…

To optimize learning experience and improve learning performance, current virtual experimental systems usually assist students with stepwise guidance before operations and feedback after them. However, stepwise and excessive guidance can lead to student overreliance, while late feedback cannot avoid potential errors during experimental learning.…

The creation and use of models in science is of great importance for knowledge production and communication. For example, toy models are often used as idealized explanatory models in physics education. Models can be a powerful tool for exploring phenomena in ways that facilitate learning. However, careful consideration of instruction and…

This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

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…

Introductory biology courses at most colleges and universities have two components: a lecture and a lab. However, for students who are not majoring in biology and taking the introductory course as part of their general education requirements, the distinct role of the lab has not been clearly articulated. We performed an online modified-Delphi…

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…

Design-Based Learning and computational thinking (CT) are two key components that support each other specifically in the learning process involving the development of experimental design. Both components emphasize the importance of integration between computational thinking and design-based learning to support a creative, innovative and data…

Aldol chemistry is highlighted in many introductory organic chemistry laboratory experiments because it provides synthesis, mechanism, and experimental challenges for students. In the experiment described here, students synthesize dibenzalacetone derivatives by crossed aldol condensation, observe reaction rates using a semiquantitative rubric, and…

Most, if not all, physics undergraduate degree programs include instructional lab experiences. Physics lab instructors, both faculty and staff, are instrumental to student learning in instructional physics labs. However, the faculty-staff dichotomy belies the complex, varied, and multifaceted landscape of positions that lab instructors hold in the…

Affect and emotions matter to science learning. They also matter because they are integral to science identity formation and sense of belonging. This study aims to foreground the epistemic and affective character of laboratory work in higher science education by conceptualizing it as epistemic practice, in which students activate their body and…

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…

Dissection is a unique multisensory educational experience and is essential to learning the anatomical construction of the human and animal bodies. This study aims to introduce a specialized design for the assessment of dissection and to discuss the assessment's attributes. The design was a product of the "assessment drives learning"…
