Summary:
Recent research in Science education has recognized the importance of history
and philosophy of science and the research procedures offer a model of learning
activity. The reporting and analysis of historical processes helps learners to
set, change and communicate with scientific representations. The history and
philosophy of science can be introduced in the classroom not necessarily
through formal courses in the history of chemistry or comments and anecdotes,
but rather by incorporating the heuristic principles that guided the scientists
to elaborate their theories.
This paper is a summary of an extensive overview article, citing a through
historical and epistemological analysis of the research strategy of scientists
during the birth of quantum theory.
The quantum theory formulated and founded the first decades of the twentieth
century. At the time, the technology was available to scientists began to take
the first experimental results from a unknown world, the world of elementary
particles (molecules, atoms, nuclei, neutrons, electrons, etc.) from a world
which is made to see and understand. The world of particles called microcosm,
which could not be explained by theories of classical mechanics, of
thermodynamics and electromagnetism, which scientists explain the theories of
macrocosm, the world can see, fell and understand.
Specifically, in this paper titled “the history of chemistry as an educational
tool. The quantum mechanical model of atom” presents the grader experimental
scientists involved in macrocosm. These are the Thomas Young with experiment
with two slits, Max Planck with radiation of black body, J.J. Thomson with his
model, Ernest Rutherford with atomic structure, Niels Bohr with Bohr’s model,
Louis de Broglie with waves materials, and Erwin Schrodinger with Schrodinger’s
equation.
The aim of this paper is to understand the contribution of the models proposed
in the processes of conceptual change from classical to quantum worldview, and
to develop educational materials for teaching use of the above.
