Campbell, Brian – Journal of Natural Resources and Life Sciences Education, 2010
Copper fungicides and bactericides are often used in tomato cultivation and can cause toxic Cu levels in soils. In order to combat this, organic matter can be applied to induce chelation reactions and form a soluble complex by which much of the Cu can leach out of the soil profile or be taken up safely by plants. Organic acids such as citric,…

Nakhleh, Mary B.; Krajcik, Joseph S. – Journal of Research in Science Teaching, 1994
Involves secondary students in a study designed to allow investigation into how different levels of information presented by various technologies (chemical indicators, pH meters, and microcomputer-based laboratories-MBLs) affected students' understanding of acid, base, and pH concepts. Results showed that students using MBLs exhibited a greater…

Gomberg, Irene L.; Atelsek, Frank J. – 1980
At the request of the National Science Foundation (NSF), the Higher Education Panel (a stratified sample of 760 colleges and universities) collected information on the level of institutional expenditures for research equipment, the federal contribution to those expenditures, and the share of funds expended for high-cost items. The data were…

Chan, K. M. – School Science Review, 1985
Provides a detailed description for the construction of equipment needed to investigate acid/base equilibria through the measurement of pH and potentiometric titrations. Suggested experiments and calibration techniques are explained. This information helps to solve the problems of inadequate, expensive equipment required for A-level chemistry…

Kim, Dongwook – ProQuest LLC, 2009
Although a number of past studies have been aimed at characterizing iron's redox properties in aqueous systems and its contribution to natural attenuation processes of groundwater contaminants, many questions remain. It is especially important to understand the molecular properties that control the reactivity of both Fe[superscript II] and…

Vergnoux, A.; Allari, E.; Sassi, M.; Thimonier, J.; Hammond, C.; Clouzot, L. – Journal of Biological Education, 2011
The impact of humans on aquatic systems is covered in French high schools in the "Premiere" level (ages 16 to 17) by students studying economics and social sciences. We designed experiments to teach critical thinking about water pollution and how citizens can act to minimise it. The experimental session, which lasts three consecutive…

Cluett, Edward; Gould, Jessica – Science Teacher, 2006
This article describes an inquiry-based activity for high school students in which they determine the pH of the digestive compartment in "Paramecia" using different pH indicators. This lab activity introduces students to the challenges of research on the cellular level and illustrates one of the primary methods that scientists use to measure the…

Digital Equipment Corp., Maynard, MA. – 1971
Computer programs which teach concepts and processes related to biology, earth science, and chemistry are presented. The seven biology problems deal with aspects of genetics, evolution and natural selection, gametogenesis, enzymes, photosynthesis, and the transport of material across a membrane. Four earth science problems concern climates, the…

Inner London Education Authority (England). – 1983
This unit on equilibrium is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit, which consists of two levels, focuses on the application of equilibrium principles to equilibria involving weak acids and bases, including buffer solutions and indicators. Level one uses Le Chatelier's…

Gonzalez-Cruz, Javier; Rodriguez-Sotres, Rogelio; Rodriguez-Penagos, Mireya – Biochemistry and Molecular Biology Education, 2003
Enzyme kinetics is a difficult subject for students to learn and for tutors to teach. During the practicals included in the biochemical courses at the Faculty of Chemistry of Universidad Nacional Autonoma de Mexico, we found that the students acquire good training in the calculations to obtain kinetic parameters such as K[subscript m], V[subscript…

McEwan, Hunter; Slaughter, Helen – Educational Perspectives, 2004
The College of Education at the University of Hawai'i at Manoa has two doctoral degrees: the PhD in educational psychology and the PhD in education. Both degrees have been in existence for over 30 years. The PhD in education, however, began its life as the EdD and was renamed the PhD in 1999. As two of the articles in this issue make clear…

Ouertatani, Latifa; Dumon, Alain; Trabelsi, Malika Ayadi; Soudani, Mohamed – International Journal of Science and Mathematics Education, 2007
In this work, we propose to identify the knowledge that Tunisian grade 10 students build up concerning acids and bases. Thus, after learning, we have proceeded by giving a paper and pencil task to students of two levels of teaching. The results obtained allow us to say that the assimilated knowledge is transitory; that the students have a worse…

Murphy, Jennifer, Ed.; Griffin, Carrie, Ed.; Higgs, Bettie, Ed. – National Academy for Integration of Research, Teaching and Learning (NJ1), 2010
The third annual conference of the National Academy for Integration of Research, Teaching and Learning (NAIRTL) was held at Trinity College Dublin on 11-12 November 2009, and was attended by over 300 delegates. The theme--"Research-Teaching Linkages: Practice and Policy"--was timely and generated some fascinating papers, workshops and…

Braxton, John M. – Review of Higher Education, 1983
A survey of male Ph.D.s in chemistry and psychology at selective liberal arts colleges showed the publication rate of department colleagues to be positively related to current publication productivity of the focal faculty member. Colleagues influenced research activity of faculty with low prior research levels, but not higher prior levels.…
