The purpose of this laboratory experiment is to study fundamental concepts of kinetics and equilibria and the isotope effects associated with both of these concepts. The concepts of isotopes in introductory and general chemistry courses are typically used within the contexts of atomic weights and radioactivity. Kinetic and equilibrium isotope…

Isothermal titration calorimetry was used to experimentally determine thermodynamic values for the ethylenediaminetetraacetic acid (EDTA)(aq) + M[superscript 2+](aq) reactions (M[superscript 2+] = Ca[superscript 2+] and Mg[superscript 2+]). Students showed that for reactions in a N-(2-hydroxyethyl)piperazine-N"-ethanesulfonic acid (HEPES)…

Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…

Students in all areas of computing require knowledge of the computing device including software implementation at the machine level. Several courses in computer science curricula address these low-level details such as computer architecture and assembly languages. For such courses, there are advantages to studying real architectures instead of…

Higher education institutions and scientific funding agencies are emphasizing international projects that involve the integration and synergy between research groups, particularly if different disciplines are involved. Students with an education that reflects these trends will have more tools to succeed in the future, but it is challenging to…

"Born out of struggle and the struggle continues" is the motto of Chicago's Social Justice High School, one of four small, autonomous schools on one campus, Little Village Lawndale High School Campus (LVLHS). LVLHS was the result of a 19-day hunger strike in May 2001 by 14 community residents demanding that funds allocated for a new high…

This article informs about the formation of a school's Institutional Review Board (IRB), presents examples of research that IRBs often encounter, elevates awareness of human subjects research concerns for faculty and staff, and discusses how emerging requirements for science competitions may affect schools, staff and students. An IRB is the group…

"ARL" is the bimonthly report on research library issues and actions from ARL (Association of Research Libraries), CNI (Coalition of Networked Information), and SPARC (Scholarly Publishing and Academic Resources Coalition). "ARL" reports on current issues of interest to academic and research library administrators, staff, and…

The authors' experiments with long-distance arts collaboration in a multiform environment began in July 2002. They consider a multiform environment to be an interactive environment where different audiences experience a shared event from different and mutually exclusive frames of reference. The Dynamic Media Project team members had extensive…

This article features the life and accomplishments of Horace Jeremiah Voorhis in the field of progressive education. Voorhis earned the first Master of Arts degree in Education awarded by the Claremont Graduate Schools after he submitted his master's thesis, "The Education of the Institution Boy: A General Outline of Policies for the Voorhis…
