This investigation was part of a multi-lesson unit that gave students direct experience using increasingly sophisticated tools to make more detailed observations and measurements of light. Through these lessons, students experienced a key aspect of the nature of science (McComas 2004), namely how scientists constantly refine and modify theories as…

This study provides qualitative analysis of data that answers the following research question: how do college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? The study concentrates on four cases and more specifically on three introductory science classes and on four…

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)

The physics of vertical jumping is described as an interesting illustration for motivating students in a general physics course to master the kinematics and dynamics of one dimensional motion. The author suggests that mastery of the physical principles of the jump may promote understanding of certain biological phenomena, aspects of physical…
