Although unrecognized for his scientific achievements during his life, Gregor Mendel pioneered our modern understanding of the gene, work that shaped the field of genetics and advances in biology and medicine. The field that he set in motion 200 years ago lies at the center of current ethical debates about the future of humanity, the limits of…

The aim of this study is to present pre-service biology teachers with reading texts about the research of Van Helmont and Joseph Priestley relate to the subject of photosynthesis, for their familiarization with the processual and contextual aspects of science and their understanding of the nature of science, and to reveal the extent to which these…

History of science (HOS) plays a substantial role in the enhancement of rooted understanding in science teaching and learning. HOS of evolution and genetics has not been included in Vietnamese biology textbooks. This study aims to investigate the necessity of introducing evolution and genetics HOS into Vietnamese textbooks. A case study approach…

Traces the history of the molecular approach to biology from the late 19th century. Describes the development of investigatory techniques as well as of knowledge of molecular structure. (EB)

Examines the history of the transformation of animal regeneration research from observations to hypothesis-based concepts as a classic example of a view of science as a human endeavor, where social context influences the nature of the science undertaken and the science in turn alters the social context. (LZ)
