Seven p-nitrophenyl benzoate esters (p-nitrophenyl benzoate, p-nitrophenyl m-anisate, p-nitrophenyl p-anisate, p-nitrophenyl m-chlorobenzoate, p-nitrophenyl p-chlorobenzoate, p-nitrophenyl m-toluate, p-nitrophenyl p-toluate) were synthesized and characterized by students in a second-semester organic laboratory course. In a subsequent laboratory…

Students have used Cogito.org to pose and/or solve math problems and brain teasers, share their experiences in academic competitions, debate the pros and cons of using biofuels for energy, design an alien world based on sound scientific principles, and expand their cultural understanding by connecting with students from around the world.…

Instructional techniques based on research in cognitive science and physics education have been used in physics courses to enhance student learning. While dramatic increases in conceptual understanding have been observed, students enrolled in these courses tend to move away from scientistlike views of the discipline and toward novicelike views, as…

The roles of science in society and the nature of science are the focus of many science curricula. Current views about these two aspects of science have largely been informed by the history of scientific development. This article uses the outbreak of severe acute respiratory syndrome--a recent health scare--as a case study to explore the roles of…

This article presents a proposed model for a clear description of K-12 age-possible engineering knowledge content, in terms of the selection of analytic principles and predictive skills for various grades, based on the mastery of mathematics and science pre-requisites, as mandated by national or state performance standards; and a streamlined,…

This study describes the influence of a secondary science methods program on secondary science preservice teachers' views and enactment of nature of science and inquiry-based instructional practices. Built into the structure of this program were three cycles of practice teaching and reflection in which the preservice teachers focused on key…

Background: The introduction of a new National Curriculum in post-apartheid South Africa heralded a different approach in education. This curriculum not only advocated the development of knowledge and skills, but also emphasised education for democracy and citizenship. It seeks to balance central control (and a single curriculum) with local…

In this paper I respond to Long's paper in which he uses an ethnographic snapshot of a rally of scientists against the perceived "dumbing down" effect of the new Answers in Genesis Museum in Kentucky to raise educational concerns about the effects of creationist influence on the science curriculum in American schools. In my response I…

Paper attempts to re-define the boundary of the science of educational technology on the basis of conceptualised technology systems. (Author)

Article provided a well-known example of creative invention, that of the hovercraft, which served well as a highlight of the problems facing the student of creativity. (Author/RK)

This article chronologically outlines discoveries and achievements made in the field of Chemistry from Ancient times to 1900. These events are classified into three categories: physical, inorganic, and organic chemistry. The approximate dates, scientists, and their countries of origin for each event are included in the time chart. (MA)

Proposes the metatheoretical stance of skeptical pluralism as a means of ordering and integrating knowledge of human communication. Uses a typology of modern philosophies suggested by Richard McKeon to identify four different conceptions of communication and science (phenomenal, operational, nationalistic, and phenomenological).

Collection of two short descriptions of chemical principles seen in life situations: the autocatalytic reaction seen in the bombardier beetle, and molecular potential energy used for quick roasting of beef. Brief reference is also made to methanol lighters. (PS)

In his remarkable treatise Reflexes of the Brain (1863) Sechenov developed a detailed program which, properly evaluated, laid the foundation for an objective science of psychology not only in Russia but on a world scale. (Author)
