Comics, which attract attention with their adaptation to changing conditions in the historical process, are increasing their popularity both in current life and in the field of education. They can be used as a powerful supplementary teaching tool concretizing abstract concepts, especially in lessons such as Science. They can also be used to convey…

The 21st century education engages students to have higher order thinking and scientific literacy skills. However, these abilities in Indonesia are still relatively low, especially students' scientific literacy skills. One solution to the problem of low scientific literacy skills in Indonesia is the application of STEM education. However, as…

Items that are chained, or blocked, together appear on many of the conceptual assessments utilized for physics education research. However, when items are chained together there is the potential to introduce local dependence between those items, which would violate the assumption of item independence required by classical test theory,…

The idea of the interaction between genes and environment in the formation of traits is an important component of genetic literacy, because it explains the plastic nature of phenotypes. However, most studies in genetics education characterize challenges in understanding and reasoning about genetic phenomena that do not involve modulation by the…

In this study, a process was designed, in which a lemon seed grew into a seedling, using the inquiry-based science learning approach. This aimed to increase the overall development of the scientific process skills of children and their sensitivity to nature. The germination, growth and development of a plant were meticulously and systematically…

Although nearly everyone is familiar with colors from an early age and the fundamentals of color mixing are taught at various abstraction levels throughout kindergarten to high school, we repeatedly observe that our student teachers in physics have problems in explaining the subject. Therefore, we propose an experimental setup that focuses on the…

The Search for Exoplanets is an interactive computer simulation, the product of a collaboration between the Departments of Physics and Astronomy and Computer Science at Purdue University. Our goal was to create a computer simulation that would introduce students to scientific principles, research methodology, and analysis of data with which…

In this paper, we present activities that help students deepen their understanding of basic electrostatics using an electroscope in combination with the photoelectric effect. The students investigate the behaviour of an isolated electroscope when the metal housing of the electroscope is charged. The activities follow the framework of the…

The catalytic hydrogenation of alkenes and alkynes is an important part of the undergraduate chemistry curriculum and is a fundamental process in chemical industry. Inquiry-based laboratory activities are presented that investigate the hydrogenation of alkynes on a nanoparticle palladium surface to form alkenes, which go on to form alkanes. Alkyne…

This comprehensive experiment is specially designed for the third-year and above students who are majoring in chemistry, applied chemistry, and chemical engineering. Students conduct experiments in groups, which are required to synthesize the CeO[subscript 2]-NiTiO[subscript 3]/attapulgite (ATTP) composite catalyst by the sol-gel method; the…

Thermal conductivity is generally the tool of choice for quantification of fixed gases, particularly lighter-than-air gases. Unfortunately, gas chromatography-thermal conductivity detectors (GC-TCDs) are difficult to introduce in first- and second-year chemistry courses where the cost and number of instruments, as well as the space required, is…

Properties of chemical substances drive a large portion of research in the sciences, but properties are very difficult to search in full text documents, and while searches in chemical information retrieval resources may help, the effective use of such resources may require considerable knowledge of the indexing and excerption policies in the…

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…

The dynamics of a spring pendulum is an important topic in introductory experimental physics courses at universities and advanced science courses in secondary school education. Different types of pendulum setups with smartphones were proposed to investigate, e.g., the gravitational acceleration, to measure spring constants, or to illustrate and…

Herein we report the design of an upper-level hybrid laboratory course in the area of applied biopharmaceuticals, which has high scheduling flexibility, and utilizes both virtual and in-person educational elements to enhance students' learning experience. This newly developed course applies chemical engineering knowledge, practical and…
