Controlling Type 1 error and encouraging reproducible research are important in clinical and translational research. These concepts are frequently discussed in lectures with mathematical language, analytic examples, and probability distributions that demonstrate the issues. However, first-time learners in biostatistics courses focusing on…

Observational learning enables us to make decisions by watching others' behaviors. The quality of such learning depends on the abilities of those we observe, but also on our beliefs about those abilities. We have previously demonstrated that observers learned better from demonstrators described as high vs. low in ability, regardless of their…

A simple, safe, and easy demonstration of the reaction of sodium peroxide with water is presented. The reaction is performed in a plastic bottle by adding water to sodium peroxide supported in a rubber "thimble"; oxygen is detected by the reignition of a glowing splint, while the generation of sodium hydroxide is indicated by…

Principal Component Analysis (PCA) is a powerful statistical technique for reducing the complexity of data and making patterns and relationships within the data more easily understandable. By using PCA, students can learn to identify the most important features of a data set, visualize relationships between variables, and make informed decisions…

A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

A mixture of salt water and isopropyl alcohol is immiscible, forming two separate liquids with the organic layer on top and aqueous layer on bottom. When universal indicator is added to such a mixture, all of the indicator compounds in the universal indicator preferentially dissolve in the alcohol--except for phenolphthalein at high pH. Mixtures…

Purpose: 360° immersive videos may be useful in procedure-based healthcare settings. We hypothesized that extended reality (XR) neonatal intubation education is a feasible alternative to live demonstration in skill and knowledge transfer. Methods: This was a prospective single center evaluation of an educational XR intubation video using Premature…

Between April and December 1915, Maria Montessori and her son, Mario Montessori, spent time in California. Historical accounts of this period have emphasized Montessori's participation in San Francisco's world's fair, the Panama-Pacific International Exposition (PPIE), and identified this event as the crux of her travels. The following text and…

The movement of air into and out of the lungs is facilitated by changes in pressure within the thoracic cavity relative to atmospheric pressure, as well as the resistance encountered by airways. In this process, the movement of air into and out of the lungs is driven by pressure gradients established by changes in lung volume and intra-alveolar…

Instructional methods are the cornerstone of all teaching and learning strategies. This study explored instructional method use by early, middle, and later career agricultural education teachers. One-hundred nine teachers responded to an online questionnaire and were evenly split in terms of gender. Cooperative learning, demonstration, and lecture…

This study explored the impact of interactive e-books on the viewing behaviors of children in science demonstrations at museums. To conduct this study, an interactive e-book on a pendulum experiment was developed and integrated into a physical science demonstration at a museum. Two scientific demonstrations were conducted in this study. The first…

This work investigates the design and usability of a novel eXtended Reality (XR) Vest, which combines two viewpoints for demonstration-based training (DBT). Traditional modalities for DBT, such as prerecorded videos and live instruction, are minimally engaging and potentially hazardous resulting in low motivation and knowledge retention. To combat…

The main objective of this intervention study was to investigate the effect of three teaching approaches, namely the traditional teaching method (TTM), a teacher-based demonstration experiment (TBDE) and a student hands-on experiment (SHE), on students' academic performance. A total number of 324 senior five students studying chemistry as one of…

The development of artificial intelligence competency on the flipped classroom with demonstration learning platform is the study that was conducted with the ideas to enhance the quality of Thai youths so that it would align with the instruction management in the age of artificial intelligence (AI), in which a number of AI applications have been…

Learning theories provide philosophically informed, basic principles for understanding the mechanisms through which people learn based on a combination of field or laboratory studies. Unfortunately, however, there are several clear conflicts between theoretical approaches and common methods in teaching. Consequently, key challenges among teachers…
