Many studies illustrate the positive influences of undergraduate research experiences on student learning, attitudes, and retention in the sciences. At our institution, over 90% of the biology majors surveyed reported a desire to participate in undergraduate research, but only 3% per year have the opportunity to work in a traditional…

Study abroad attempts to prepare students to effectively work in a multi-national environment. This study compares students' experiences in a unit operations laboratory course offered in multiple modalities: at students' home university, and four- and eight-week study abroad. The results examine the impact of support on students' learning and…

"The How and Why of Laboratory Schools: Innovations and Success Stories in Teacher Preparation and Student Learning" is an eagerly anticipated exploration crafted by esteemed researchers and practitioners from some of the foremost Laboratory Schools across the United States and internationally. These institutions, also recognized as…

The Tesla coil is one of the most famous and popularly recognizable high voltage devices. Utilizing the fame of recognizability of the Tesla coil in a "Build Your Own" laboratory exercise is a great way to create a successful and highly interesting learning activity. Classical Tesla coils utilize a spark gap as the primary switch,…

Recently available local positioning systems (LPS) have the potential to be used for interactive physics laboratory activities and classroom demonstrations. The Pozyx LPS combines multiple sensors with position data for any object that one of the devices is attached to. Devices referred to as "tags" (Fig. 1[a]) are mobile devices that…

Several educational trials on handling viruses and or virology have been reported. However, given their small size, direct visualization of these viruses under a microscope has been rarely performed. The so-called "giant viruses" are larger than other viruses with a particle size greater than 200-300 nm. This enables their direct…

Medical schools are increasingly integrating professionalism training into their gross anatomy courses, teaching ethical behavior and humanistic attitudes through the dissection experience. However, many schools continue to take a traditional, technical approach to anatomical education while teaching professionalism in separate courses. This…

Aim of the present study is to analyze science teacher candidates' laboratory videos by using Many-facet Rasch model. Survey method was used in the study. The study was conducted in 2017-2018 academic year spring semester. Rasch model's surfaces are respectively: 9 juries, 13 science activities and 19 criteria. FACETS program was used for data…

Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy is an incisive technique for the characterization of paramagnetic centers in inorganic, bioinorganic, and organic molecules and materials. These measurements are enabled with the help of paramagnetic species, such as organic free radicals and ions, electronically…

In this supplement to our second-year supercapacitor lab (Bringing Real-World Energy-Storage Research into a Second-Year Physical-Chemistry Lab Using a MnO[subscript 2]-Based Supercapacitor. "J. Chem. Educ." 2018, 95 (11), 2028-2033), we incorporate a color indicator as indirect evidence for the manganese oxide's pseudocapacitive…

In the laboratory experiment described here, students synthesize silver nanostructures (AgNS) with different shapes and sizes to elucidate the shape- and size-dependent optical properties of nanostructured materials. Students also develop understanding of some thermodynamic and kinetic aspects of the synthesis process through this experiment. In…

When student projects require an analytical step that is robust and sufficiently selective, high performance thin layer chromatography (HPTLC) is a method to be considered. However, for student laboratories not equipped for HPTLC, sample application as a sharp narrow band is a hurdle. The low eluting power of water on reversed phase plates can be…

This technology report outlines the design and construction of a simple Arduino-based pH sensor using universal pH paper; it can be assembled for less than $40 and is ideal for use in laboratory classrooms teaching students with visual disabilities. The device is simple to construct and suitable for adoption in school chemistry laboratories…

The first purpose of this study was to introduce a laboratory modelling activity focusing on teaching the concepts of radioactive elements/atoms, radioactive decay, and half-life. The second was to investigate pre-service chemistry teachers' understanding of these concepts. Fifteen pre-service chemistry teachers who had enrolled in a Physical…

A laboratory experiment was developed to introduce students to waste valorization. This is the process of reusing, recycling, or composting from wastes, useful products, or sources of energy. In this laboratory experiment, waste valorization is demonstrated through transforming waste orange peel (WOP) into a marmalade-type gel by extracting a…
