A layered interpretation of the history of chemistry is discussed through chemical revolutions. A chemical revolution or rupture, discontinuity, transition mainly by emplacement, instead of replacement, procedures were identifed by: The fourth chemical revolution, fundamentally characterized by the incorporation of new instruments in chemical practices is discussed.

A new chronology is introduced to address the history of chemistry, with educational purposes, particularly for the end of the twentieth century and here identified as the fifth chemical revolution. The fifth revolution developed from to and is characterized by a deep transformation in the very heart of chemistry.

That is to say, the size and type of objects substancesthe way in which they must be done and the time in which they are transformed. History of chemistry Chemical revolutions Chemistry education Exemplars Instruments and subdisciplines. We studied steroid research from to that led to the discovery of the contraceptive pill and cortisone. This course of events, which was unprecedented at that time in a developing country, was interrupted when Syntex moved its research division to the US, leaving Mexico with a small but productive research group in the chemistry of natural products.

Steroids contraceptive pill Syntex. This paper attempts to show one of the ways history of chemistry can be teachable for chemistry teachers, it means something more than an undifferentiated mass of names and dates, establishing a temporal framework based on chemical entities that all students use. Represents a camizo equilibrium between over-simplification versus overelaboration.

Hence, following the initial proposal of Jensen J Chem Educ These three revolutions are called by the chemical structural entities that emerged from the same: The focus of this article will be centered on five Spanish chemists who were refugees in Mexico after the Civil War cahmizo provided a strong drive in developing Mexican chemistry.

This article starts with chamizp panorama of science in Europe mainly Spain and in Mexico from the end of the 19th Century to the beginning of the 20th century. It is also included the development of chemistry in Germany in the 19th century. A conclusion is the importance of their contribution to Mexican chemistry through two institutions: In this article, from the characterization of technoscience of the English historian J.

Pickstone and the recognition of the importance of models and modelling in research and teaching of chemistry, the term technochemistry is introduced as a way of chemical knowledge.

With the above new possibilities for rethinking the farritz curriculum are opened. The synthesis of new chemical compounds makes it the most productive science. Unfortunately chemistry education practice has not been driven to any great extent by research findings, philosophical positions or advances in new ways of approaching knowledge. The changes that have occurred in textbooks during the past three decades do not show any real recognition of these.

Following the proposals of T. Jensen on scientific revolutions, in this article history of chemistry is split up into five great revolutions ; ; ; and and the public image of chemistry around them is examined. History Chemistry Revolutions Paradigms. Heuristic diagrams have the purpose of helping students or teachers, or researchers to understand their own research considering that asks and problem-solving are central to scientific activity. Mexican science teachers without experience in science education research used the heuristic diagram to learn about the history of chemistry considering also in the left side two different historical times: Considering the difficulties identified by the philosophers of science to the universal and unique scientific method, the method of the chemistry is characterized with the analysis and the synthesis.

Through same it is possible to explain the exponential growth of the chemical information in the last years. Today there are little more of 3 million chemist all over the world producing aboutpapers a year. They produce new substances — from some hundreds in to about 20 million now — the vast majority artificial.

This rate is growing quite fast. Once the majority of chemistry teachers all over the world used textbooks as the main sometimes the only source of information, we became, without wanting to It must include an understanding of the nature and process by which scientific activities are carried out.

Recognition of the exponentially chemistry knowledge growth and the incompleteness of the current chemistry textbooks are thus intimately related to recognition of the need for recurrent historical teaching models.
