Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

In a typical chemistry instrumentation laboratory, students learn analytical techniques through a well-developed procedure. Such an approach, however, does not engage students in a creative endeavor. To foster the intrinsic motivation of students' desire to learn, improve their confidence in self-directed learning activities and enhance their…

An instrumentation-based laboratory curriculum combining traditional unknown analyses with student-designed projects has been developed for an introductory analytical chemistry course. In the first half of the course, students develop laboratory skills and instrumental proficiency by rotating through six different instruments performing…

Gas chromatography-mass spectrometry (GC-MS) is a powerful analytical tool for detection, identification, and quantification of many volatile organic compounds. However, many colleges and universities have not fully incorporated this technique into undergraduate teaching laboratories despite its wide application and ease of use in organic…

At the beginning of the nineteenth century, the core of a typical teaching collection was composed by apparatus, which were very similar to the ones proposed in the eighteenth century by 's Gravesande, Nollet, Desaguliers and others lecturer demonstrators and makers. Since 1820 circa, new didactic instruments were introduced. Most of them…

My point of departure in this essay is that student approaches to assessment appear to have become more instrumental, and that there has been a correlative propensity in my teaching practice to "teach to the test". Hence, both learners and teachers seem to have become more strategic in relation to assessment. This situation, I argue, is…

Calibration is a technique that is commonly used in science and engineering research that requires calibrating measurement tools for obtaining more accurate measurements. It is an important technique in various industries. In many situations, calibration is an application of linear regression, and is a good topic to be included when explaining and…
