This paper reports a simple magnetically driven oscillator, designed and resolved in order to achieve a better student understanding and to overcome certain instructional difficulties. The apparatus is mainly comprised of an ordinary spring pendulum with a neodymium magnet attached to the bottom, a coil placed in the same vertical direction, an…

The purpose of this action research proposal is to create a Modification of Instruments and Tools in Science (MITS) program to address the need for providing Students With Disabilities (SWDs) appropriate access to scientific tools and techniques of scientific inquiry. This proposal contains a review of literature on SWDs, differentiating…

The introduction of outcomes-based education in South Africa placed many challenges on the transformation of science classrooms. The 2009 National Education Evaluation and Development Unit (NEEDU) Report concluded that South African rural and township schools are largely dysfunctional. This article examined some of the reasons for the…

Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National…

This study focuses on the availability and use of Science Laboratories at the secondary education level in Visakhapatnam District of Andhra Pradesh, India. It is commented that most of the schools do not possess well equipped laboratories and even when equipment is available some science teachers are not utilizing the laboratory facilities.…

This investigative laboratory exercise uses the different relations between ambient temperature and metabolic rate in endotherms and ectotherms as a core concept to answer the following question: What thermoregulatory mode is employed by chicken embryos? Emphasis is placed on the physiological concepts that can be taught with this exercise,…
