The term "throughput" refers to the percentage of a student cohort who complete a course sequence within a set period after having begun that sequence at the same point in time. Under AB 705 the set period for observing throughput rates is described in law as "one year". While that time frame seems intuitive enough, the…

A versatile experiment is described for the high school and college laboratory setting based on the synthesis of biobased polymers prepared from inexpensive, renewable, and nonhazardous chemicals. Combinations of readily available citric acid, glycerol, and tapioca root starch are used to prepare three polymeric materials with different observable…

Dyslexia is a specific learning disability that impacts word reading accuracy and/or reading fluency. Over half of the states in the USA have passed legislation intended to promote better identification of individuals with dyslexia. To date, no study has been conducted to investigate the potential impact of state laws on the identification of…

Zero tolerance discipline policies have come under criticism as contributors to racial discipline gaps; however, few studies have explicitly examined such policies. This study utilizes data from two nationally representative data sources to examine the effect of state zero tolerance laws on suspension rates and principal perceptions of problem…

In these two classroom demonstrations, students observe the reaction between H[subscript 2] gas and Pd foil. In the first demonstration, hydrogen and palladium combine within one minute at 1 atm and room temperature to yield the non-stoichiometric, interstitial hydride with formula close to the maximum known value, PdH[subscript 0.7]. In the…

The stochastic simulation of chemical reactions, specifically, a simple reversible chemical reaction obeying the first-order, i.e., linear, rate law, has been presented by Martinez-Urreaga and his collaborators in this journal. The current contribution is intended to complement and augment their work in two aspects. First, the simple reversible…

First Peoples' knowledge at university lies within a contested knowledge space. The incompatibilities and differences between Western and First Peoples' knowledge systems means attempts to superficially 'add' First Peoples' content to university courses are often ineffective and tokenistic. Considering these issues, this paper reflects on the…

Nationally, one in four high school students drops out in high school. Georgia, in particular, is very concerning with a 67% high school completion rate (Hickman & Heinrich, 2011) and a 41% drop out rate recorded for girls (National Women's Law Center, 2007). While these statistics are disturbing, they do not do justice to the reality of the…

A simple method for studying the kinetics of a chemical reaction is described and the significance of reaction orders in deducing reaction mechanisms is demonstrated. In this student laboratory experiment, oxidation of iodide by iron(III) ions in an acidic medium is transformed into a clock reaction. By means of the initial rates method, it is…

Provides background information for teachers on the rate laws for reversible reactions. Indicates that although prediction of the form of the rate law for a reverse reaction given the rate law for the forward reaction is not certain, the number of possibilities is limited because of relationships described.

An experiment in chemical kinetics as part of our Discovery Chemistry curriculum is described. Discovery Chemistry is a pedagogical philosophy that makes the laboratory the key center of learning for students in their first two years of undergraduate instruction. Questions are posed in the pre-laboratory discussion and assessed using pooled…

Herein we present a modified iodine clock experiment which replaces starch with cellulose paper. This provides the reaction with a white solid surface in which color change can be clearly observed and reduces reagent amounts required to 540 µL per group. After data acquisition, students are required to calculate reaction orders and the reaction…

The Every Student Succeeds Act (ESSA) comprehensively reauthorized the Elementary and Secondary Education Act of 1965 (ESEA). Among other changes, the ESSA amended federal K-12 educational accountability requirements for states and local educational agencies (LEAs) receiving ESEA funds, including those regarding the identification, support, and…

Domestic violence is a purposeful use of force or strength on a person within and outside the house which affects the person adversely or the society at large. Therefore, this study examined the influence of domestic violence among Senior Secondary School Girls in Itesiwaju Local Government Area of Oyo State. Ex-post facto research design was…

The absorbance decay of hexacyanoferrate(III) as a function of time shows a progressive deviation from zero to first order. This variation follows an experimental rate law that has been analyzed. The change in reaction order is due to a change in the relative rate of substrate oxidation with respect to that of catalyst regeneration. (Contains 2…
