The first six years of a child's life are the most critical years for development, and appropriate health care, nutrition, stimulation, affection, and education are critical for healthy development. These early years also present a window of opportunity to mitigate any developmental concerns. With the right intervention, the child's health,…

This article describes an experiment that can be done in the classroom in a simple way, with the support of a "homemade" device or as a laboratory practice with the support of PASCO equipment. Through a theory-practice sequence, kinematic and dynamic equations were checked with qualitative and quantitative analysis, emphasizing the…

This paper presents apps designed to assist students in understanding and developing proofs in geometric theorems. These technologies focus on triangle congruence, triangle similarity and properties of parallelograms. Focus group discussions and initial testing of the apps revealed that the apps offered a more engaging medium for learning proving…

Technological applications in education are altering how we collect information, conduct research, and share data with others. New computerized tools are changing the education community and how we pass knowledge to students. With these new tools, technology is being integrated into the classroom at larger scales every year. With more electronic…

The "Listening to Music" course is an important link in the music education of a child. The "Listening to Music" course fosters love and interest in music, teaches to understand its language, and develops emotional responsiveness in children. The article considers new opportunities in teaching the "Listening to Music"…

Drug design and development requires collaboration among scientists with diverse expertise. In early-stage drug design, establishment of promising drug candidates requires integration of structure-based molecular design with biopharmaceutics and ADMET (absorption, distribution, metabolism, excretion, and toxicity) principles. Much of this work is…

By framing entrepreneurship courses in the context of interdisciplinary team projects, students build important work-related skills whether they pursue an entrepreneurial path or employment after graduation. However, the traditional classroom environment is not conducive to realistic interdepartmental interactions found in most corporations or…

The commercialization of virtual reality (VR) hardware has enabled the use of VR as an educational tool. We describe how a VR platform was used to create molecular visualizations using standard PDB files with the purpose of delivering biochemistry and cellular biology lessons for undergraduates. Specifically, we describe two new software modules,…

This paper proposes an experiment in which students build microdevices for conveniently electrolyzing water and use image recognition and processing technology to measure the volume of gas generated during the reaction in a noncontact way. Taking advantage of three ratio relationships between (i) gas volume and the area of bubbles, (ii) the…

This article describes a simple exercise using a free, easy-to-use, established online program. The exercise helps to reinforce protein purification concepts and introduces undergraduates to pH as a parameter that affects anion-exchange chromatography. The exercise was tested with biochemistry majors at California State University-Chico. Given the…

Using tangible models to help students visualize chemical structures in three dimensions has been a mainstay of chemistry education for many years. Conventional chemistry modeling kits are, however, limited in the types and accuracy of the molecules, bonds and structures they can be used to build. The recent development of 3D printing technology…

Excel spreadsheets are used as an excellent tool in physics laboratory experiments related to wave optics. This paper presents a simple way to simulate diffraction of waves through a slit using Excel spreadsheets without any tedious programming. These simulations are used to visualize the effect of variation of different parameters such as number…

This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals ("if") and disjunctions ("or"), unlike those in logic, refer to conjunctions of epistemic…

The frequency ratios for the just diatonic scale are obtained by identifying musical intervals corresponding to Lissajous figures. The demonstration integrates the engineering physics of Lissajous patterns with the recognition of musical intervals through simple ear training. A free HTML5 app has been developed for this class activity and the…

Photographic editing technology has led to a popular style among artists: digitally manipulated photographs. The manipulations include composites, syntheses, as well as alterations of color, shape, composition, and perspective. These manipulated photographs carry impressive effects and shock value, but more importantly, they communicate…
