Sophomore liberal arts and engineering students enrolled in a course to learn and practice some basic chemical engineering side by side. The course was developed around the theme of indigo dyeing, which has an interesting history, fascinating chemistry and is accessible to all students. The students participated in a variety of active learning…

Increasing numbers of college students own cell phones, and many of these phones are smartphones, which include features such as still and video cameras, global positioning systems, Internet access, and computers as powerful as the desktop models of only a few years ago. A number of chemical educators are already using these devices for education.…

Stereotype threat is frequently purported to be an important determinant of gender gaps in math. Unlike prior studies, which mostly occur in lab settings, I use data from the National Assessment of Educational Progress (NAEP)--a large, representative assessment of U.S. children--where through a design quirk, students are randomly assigned test…

This is a story of a failed study. In 2007, the authors set out to demonstrate that Kurzweil 3000, an adaptive text-to-speech software program, would help any student revise with its read-aloud function and numerous writing tools. During the course of the study, the authors confronted their misconceptions about students' technology use and…

Ask students to name the aspects of science class they enjoy most, and working on labs will undoubtedly be mentioned. What often won't be included, however, is writing lab reports. For many students, the process of exploration and data collection is paramount, while the explanation and analysis of findings often takes a backseat. After all, if…

Research Findings: Three infants were followed over the course of 9 months from their last semester in their infant classroom through their transition to a toddler classroom at a university-based child care center. Using participant observation, video observation, and teacher interview, we qualitatively constructed and analyzed profiles of each…

Shades of Pink study describes how six preschoolers and their teacher engaged in a collaborative learning project through which they learned about the shades of a color--in this case, pink. As the children learned through experimenting and discussing their theories, they represented ideas using art as a tool for discovery and learning. The study…

Research apprenticeships for secondary students provide authentic contexts for learning science in which students engage in scientific investigations with practicing scientists in working laboratory groups. Student experiences in these research apprenticeships vary depending on the individual nature of the laboratory in which students have been…

The purpose of this study is to examine the effects of a new approach to performance appraisal training. Motivated by split-brain theory and existing studies of cognitive information processing and performance appraisals, this exploratory study examined the effects of a whole-brain approach to training managers for implementing performance…

Constant technological advancement has facilitated access to digital cameras and cell phones. Involving students in a video production project can work as a motivating aspect to make them active and reflective in their learning, intellectually engaged in a recursive process. This project was implemented in high school level physics laboratory…

Two of the most frustrating things for me as a teacher are the way units and jargon can get in the way of understanding concepts. When I teach pre-nursing and medical students about blood pressure, they end up memorizing a lot of information that would be obvious if they had remembered some of their basic physics--particularly the ability to…

A multiplex allele-specific PCR analysis was developed to identify six "common" genotypes: AA, AO, BB, BO, OO, and AB. This project included a pre-laboratory exercise that provided active learning experiences and developed critical thinking skills. This laboratory resulted in many successful analyses, which were verified by student knowledge of…

This manuscript reports on efforts to introduce beginning college students to the modern nanoscience field. These include: implementing selected experiments into sequencing core first-year and second-year chemistry laboratory courses; providing students with a first research experience; and engaging them in service learning and outreach programs…

Lessons and homework problems involving a pendulum are often a big part of introductory physics classes and laboratory courses from high school to undergraduate levels. Although laboratory equipment for pendulum experiments is commercially available, it is often expensive and may not be affordable for teachers on fixed budgets, particularly in…

The formation constant of iron(III) complex with glycine (Gly) ligand in aqueous acidic medium (0.2 M HNO[subscript 3], I = 0.2 M at 28 plus or minus 1 degree C) was determined spectrophotometrically in which a competing color reaction between Fe(III) and SCN[superscript -] was used as an indicator reaction. Under the specified conditions Fe(III)…
