A laboratory exercise has recently been reported in which the students use the initial rates method based on the clock reaction approach to deduce the rate law and propose a reaction mechanism for the oxidation of iodide by iron(III) ions. The same approach is used in the exercise proposed herein; the students determine the dependence of the…

Victims of sexual assault are often advised to seek postassault medical care to have a forensic exam, which includes evidence collection (termed a "sexual assault kit" [SAK]). After the exam, law enforcement personnel are supposed to submit the SAK to a crime laboratory for analysis. However, recent media reports suggest that in many communities…

Building on recent linguistic-anthropological work that investigates the temporalities of educational processes, the article examines how a marginalized classroom identity is interactionally formed over time in an undergraduate chemistry laboratory. The analysis demonstrates how social marginalization is enacted along multiple temporal scales via…

Research Findings: Utilization-focused, process evaluations of university-based laboratory preschools in their role with teacher preparation programs are rare in the current literature. This paper describes a self-study evaluation designed and implemented at a university laboratory preschool. A theory approach logic model was developed and used to…

What happens to education when the potential it helps realizing in the individual works against the formal purposes of the curriculum? What happens when education becomes a vehicle for its own subversion? As a subject-forming state apparatus working on ideological speciesism, formal education is engaged in both human and animal stratification in…

A technique for automatic error analysis using interval mathematics is introduced. A comparison to standard error propagation methods shows that in cases involving complicated formulas, the interval approach gives comparable error estimates with much less effort. Several examples are considered, and numerical errors are computed using the INTLAB…

New representational technologies, such as virtual microscopy, create new affordances for medical education. In the article, a study on the following two issues is reported: (a) How does collaborative use of virtual microscopy shape students' engagement with and learning from virtual slides of tissue specimen? (b) How do visual and conceptual cues…

The discovery of a Victorian-era microscope slide titled "Grouped Flower Seeds" began an investigation into the scientific and historical background of the antique slide to develop its usefulness as a multidisciplinary tool for PowerPoint presentations usable in contemporary biology classrooms, particularly large-enrollment sections. The resultant…

The Atlanta Sociological Laboratory is the moniker bestowed on scholars engaged in sociological research at Atlanta University between 1895 and 1924. Under the leadership of W. E. B. Du Bois, 1897-1914, this school made substantive yet marginalized contributions to the discipline. Its accomplishments include, but are not limited to, its…

This study investigated the learning dimensions that occur in physical and virtual inquiry-based lab investigations, in first-year secondary chemistry classes. This study took place over a 2 year period and utilized an experimental crossover design which consisted of two separate trials of laboratory investigation. Assessment data and attitudinal…

Over the past decade, several reports have recommended a shift in undergraduate biology laboratory courses from traditionally structured, often described as "cookbook," to authentic research-based experiences. This study compares a cookbook-type laboratory course to a research-based undergraduate biology laboratory course at a Research 1…

Writing activities are a sure way to assess and enhance students' science literacy. Sometimes the author's students use technical writing to communicate their lab experiences, just as practicing scientists do. Other times, they use creative writing to make connections to the topics they're learning. This article describes both types of writing…

Much of the National Science Education Standards (NRC 1996), aside from the inquiry and teaching sections, focus on content. The authors' call is instead to build standards that focus on what students need to be scientifically literate in 10 or 15 years. Although a basic understanding of important scientific concepts and an understanding of how…

As the population of international--and particularly Chinese--students grows in US academic institutions, it is critical that writing center tutors be able to address these students' needs. However, whereas writing tutors at the author's institution are often taught to be indirect and focus on higher order concerns, such strategies are not always…

The use of virtual laboratories has become an increasing issue regarding science laboratories due to the increasing cost of hands-on laboratories, and the increase in distance education. Recent studies have looked at the use of virtual tools for laboratory to be used as supplements to the regular hands-on laboratories but many virtual tools have…
