A one semester undergraduate biochemistry laboratory experience is described for an understanding of recombinant technology from gene cloning to protein characterization. An integrated experimental design includes three sequential modules: molecular cloning, protein expression and purification, and protein analysis and characterization. Students…

The development and evaluation of a two-session laboratory class, based on Geneswitch technology and sex determination in the fruit fly Drosophila melanogaster, is described. Geneswitch system allows conditional control of gene expression. A laboratory exercise has been devised for sophomores in order to illustrate how Geneswitch technology can be…

In recent years, nanomaterials have entered our daily lives via consumer products; thus, it has become increasingly important to implement activities to introduce these novel materials into chemistry curricula. Here we introduce a newly developed fluorescent nanomaterial, carbon dots, as a more environmentally friendly alternative to heavy-metal…

Several traditional chemistry lab experiences were replaced with a problem-based learning (PBL) experience in a university general education, conceptual chemistry course. Students worked in small groups on an authentic chemistry problem in which each student played a different role (Scientist, Engineering, Marketing Manager, Safety Officer, or…

The novelty of three-dimensional visualization technology (3DVT), such as virtual reality (VR), has captured the interest of many educational institutions. This study's objectives were to (1) assess how VR and physical models impact anatomy learning, (2) determine the effect of visuospatial ability on anatomy learning from VR and physical models,…

Serious game-based learning coupled with just-in-time teaching strategies was applied by offering six different questionnaires to evaluate student knowledge about the safety issues and theoretical concepts and protocols of laboratory exercises. The questionnaires were presented with an appearance similar to that of computer games by means of the…

Transforming fluorescence spectrometers into cost-effective, portable devices provides the potential for field-based applications in biological, environmental, and clinical research and education. However, the majority of developed spectroscopic technologies continue to require heavy, expensive equipment and trained personnel for operation or do…

With the adoption of instructional laboratories that require students to make their own decisions, there is a need to better understand students' activities as they make sense of their data and decide how to proceed. In particular, understanding when students do not engage productively with unexpected data may provide insights into how to better…

Chemistry of the environment has been a long-standing and important area of scientific research. Atmospheric chemistry is of particular interest in society due to the impact that rising levels of pollutants are having on the climate. It is well-known that combustion processes create CO and NO[subscript x], which leads to the creation of other…

A computational biochemistry laboratory, fitted for bioinformatics students, is presented. The molecular dynamics package GROMACS is used to prepare and simulate a solvated protein. Students analyze the trajectory with different available tools (GROMACS and VMD) to probe the structural stability of the protein during the simulation. Students are…

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…

Every day we deal with chemistry in various forms, but sometimes we don't see that. An example is biosensors that help us to evaluate health conditions, monitor environmental pollution and ensure food freshness. The most well known (and most widely sold) is the biosensor for blood glucose measurement, used every day by people with diabetes.…

A high variety of experimental model organisms have been used in developmental biology practical lectures. The work with developing embryos is crucial to make students aware of the multiple biological phenomena underlying normal animal embryogenesis and morphogenesis and represent a unique experimental platform to analyze the impact of molecular…

As medical programs place increasing importance on competency-based training and surgical simulations for residents, anatomy laboratories, and body donation programs find themselves in a position of adapting to changing demands. To better assess the demand for "life-like" cadaveric specimens and evaluate the possible impacts that…

The "transportability" of laboratory findings to other instances than the original implementation entails the robustness of rates of observed behaviors and estimated treatment effects to changes in the specific research setting and in the sample under study. In four studies based on incentivized games of fairness, trust, and reciprocity,…
