Differential equations are widely used tools for modelling the world around us, making a course in differential equations a natural place for students to connect concrete mathematical applications to abstract concepts. Since students grasp the concepts better by applying them, introducing differential equations through modelling becomes essential.…

The continuous distillation experiment in the Unit Operations Lab was moved to a virtual platform. Students used old data and equipment specifications to simulate the column in Aspen HYSYS. Students experimented without the limitations of existing equipment. For example, they studied the number of trays in the virtual column, something that is…

Change has been described as detrimental for later memory for the original event in research on retroactive interference. Popular accounts of retroactive interference treat learning as the formation of simple associations and explain interference as due to response competition, perhaps along with unlearning or inhibition of the original response.…

Over the past decade the Accreditation Board for Engineering and Technology, Inc. (ABET) has changed the general chemistry requirements to include a single introductory course for most engineering majors. There is a focus on outcomes that equip students with the ability to pass the Fundamentals of Engineering (FE) Exam and to work in…

This chapter explores early impacts from the Florida College system's bold experiment in making placement testing and developmental education optional for most students.

The advantages of active learning approaches have prompted national recommendations for the development of inquiry-based laboratories to replace traditional laboratory classes. However, there is little consensus for the most-effective implementation strategies. Frequently, a single inquiry-based exercise is incorporated at the end of a traditional…

Measuring the heat capacity ratios, [gamma], of gases either through adiabatic expansion or sound velocity is a well established physical chemistry experiment. The most accurate experiments depend on an exact determination of sound origin, which necessitates the use of lasers or a wave generator, where time zero is based on an electrical trigger.…

Hardware security is one of the most researched areas in the field of security. It focuses on discovering and understanding attacks and countermeasures for electronic hardware that provides the "root-of-trust" for modern computing systems upon which the software stack is built. The increasing reliance on electronic devices in our…

In 2018 the Gulf coast of Florida suffered extensive damage from harmful algal blooms (HABs), from as far north as Clearwater Beach south to Naples. The bloom lasted nearly a year, picking up in intensity during the late summer months. HABs occur when conditions such as reduced salinity, higher water temperatures, light saturation, and currents…

Throughout the general chemistry lab curriculum, a common shortcoming is the way in which students measure, record, and manipulate quantitative data. From initial measurements with different digital and analog instruments to proper conversions, calculations, and comparisons, students are often expected to be experts before they have been taught…

Previous research has suggested that people are unable to correctly choose which unfamiliar voice and static image of a face belong to the same person. Here, we present evidence that people can perform this task with greater than chance accuracy. In Experiment 1, participants saw photographs of two, same-gender models, while simultaneously…

When they arrive at community colleges or open-enrollment universities, most students take placement exams in English and mathematics to determine whether they are ready for college-level courses. Students with low scores are referred to developmental--remedial--courses. Forty percent of all entering college students and over half of entering…

Background: Cluster randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

This teaching experiment provided students with continuous engagement in a problem-solving based instructional approach during one mathematics unit. Three sections of sixth-grade mathematics were sampled from a school in Florida, U.S.A. and one section was randomly assigned to experience teaching through problem solving. Students' problem-solving…

Four experiments investigate the influence of topic status and givenness on how speakers and writers structure sentences. The results of these experiments show that when a referent is previously given, it is more likely to be produced early in both sentences and word lists, confirming prior work showing that givenness increases the accessibility…
