A computational experiment investigating the [superscript 1]H and [superscript 13]C nuclear magnetic resonance (NMR) chemical shifts of molecules with unpaired electrons has been developed and implemented. This experiment is appropriate for an upper-level undergraduate laboratory course in computational, physical, or inorganic chemistry. The…

This computational experiment presents qualitative molecular orbital (QMO) and computational quantum chemistry exercises of NO, NO[superscript+], and NO[superscript-]. Initially students explore several properties of the target molecules by Lewis diagrams and the QMO theory. Then, they compare qualitative conclusions with EHT and DFT calculations…

The formation and the hydrolysis of organic salts produced by the titration of a 0.1 M solution of the following amines: methyl-, dimethyl-, trimethyl-, ethyl-, diethyl-, and triethylamine with a 0.1 M solution of acetic, chloroacetic, and dichloracetic acids are studied. The pK[subscript b] of the amine and the pH at the end point were determined…

The synthesis of N-methoxycarbonyl-2-imidazolidone, an analogue of biotin, was conducted by organic chemistry students and confirmed using FT-IR and H NMR. Spectroscopy students used FT-IR to measure the rate of hydrolysis of the product and determined the rate constant for the reaction using the integrated rate law. From the magnitude of the rate…

Measurement of protein denaturation and protein folding is a common laboratory technique used in undergraduate biochemistry laboratories. Differential scanning fluorimetry (DSF) provides a rapid, sensitive, and general method for measuring protein thermal stability in an undergraduate biochemistry laboratory. In this method, the thermal…

The "FluSpec" educational software package is a fully contained tutorial on the technique of fluorescence spectroscopy as well as a simulator on which experiments can be performed. The procedure for each of the experiments is also contained within the package along with example analyses of results that are obtained using the software.

An elective course, "Toward the Greening of Our Minds": Green and Sustainable Chemistry, has been offered at Washington College since 2005. This new course without laboratory is designed for chemistry and biology majors and minors who have previously taken two semesters of general chemistry and organic chemistry. Due to the popularity of…

A simple adaptation of traditional "chemistry kit" condensers for the organic chemistry teaching laboratory is described. These waterless condensers have been employed safely with most solvents. They can be easily fabricated, stored, and used in the same manner as water-cooled condensers. These condensers were utilized in several…

The aim of this study was to determine the preferences of primary school children in relation to the types of activities that typically take place in music classrooms. For the purposes of this study, these classroom-based music activities have been categorised into five areas: singing, playing instruments, listening, reading and writing music and…

In Chinese society over the last two decades, modernisation and globalisation, together with the transition to a market economy, have created new imperatives and challenges for the school music curriculum. As a result, the 2011 reform of the Curriculum Standards for Primary Education and Junior Secondary Education marks the first time that the…

This research examines the work of four elementary music educators who strive to challenge the dominant paradigm of music education. I employed the methodology of a multiple case study to consider the discourses, practices and philosophies of these four educators. I observed in each school for an eight-week period for two full days each week,…

The purpose of this study was to examine young children's definitions of what it means to be a "good musician" and perceptions of themselves as good musicians. The researcher conducted interviews with 347 students in grades 1 through 4 in one US school district, coded the transcripts for salient characteristics and calculated…

This paper examines the intrinsic potential for well-being outcomes in a heritage-related music project. We look at how creative activities that are embedded in a community can serve to enhance the cohesion and well-being of communities through the work of its youth groups. The paper also examines the important roles of partnership working and…

This study examined computer-mediated communication (CMC) -- blogs and responses to YouTube postings -- to better understand how CMCs reflect adolescents' attitudes towards musicians playing instruments that cross gender stereotypes. Employing purposive sampling, we used specific search terms, such as "girl drummer", to identify a…

In this article, we argue that music teachers working in a fast-changing society could focus on envisioning their students' imaginary spaces for engaging with music and equipping them for leaping into what for the students would be the musically hitherto unexplored. Taking Christopher Small's writings as a point of departure, we contest…
