Embryos in Wax: Models from the Ziegler Studio is a history of embryo wax modeling written by science historian Nick Hopwood. Published by the Whipple Museum of the History of Science University of Cambridge and the Institute of the History of Medicine University of Bern, 2002, the book, like the wax models, helps exemplify the visual and material culture of science. The first half of the book describes the modeling work of Germany's Adolf and son Friedrich Ziegler during the rise of developmental embryology from 1850 to 1920, a time when embryology's practitioners needed educational aids that could help teach students in laboratories and lay persons in public lectures. Three-dimensional wax models provided just this visual aid.
Clifford Grobstein was a traditional, influential, and highly innovative biologist of the mid-twentieth century, gifted with many character facets and pragmatic talents. His early adulthood passion of linking classical embryology with developmental anatomy and medicine was joined by his later pursuit of combining research ethics and science education with public policy.
The Marine Biological Laboratory in Woods Hole, Massachusetts, began in 1888 with one building housing researchers upstairs and students in a shared lab and lecture space downstairs. For the first two years, instruction took the form of general lectures covering a range of topics in zoology. In addition, the trustees offered some public lectures in Boston to raise funds for the lab.
Henry Havelock Ellis was born on 2 February 1859 at Croydon in Surrey, England, to Susannah Wheatley Ellis and Edward Peppen Ellis, a sea captain. A psychologist, essayist, and physician, he is best known for his contributions to the study of human sexuality and his support of sex education and women's rights. Ellis 's work catalyzed the revolution against repressive Victorian views of sexuality. He was practicing and writing during an era in which attitudes about sex were beginning to change thanks to the activism of several key players in the fight for sexual equality and controlled reproduction. The rise of the more liberal modern approach to human sexuality seen in the first half of the twentieth century is due largely to the efforts of Ellis and other reproductive rights champions like Margaret Sanger and Marie Stopes.
Biologist William Keith Brooks studied embryological development in invertebrates and used his results as evidence for theories of evolution and ancestral heredity. He founded a marine biological laboratory where his and others' embryological studies took place. Later in life, Brooks became head of the Biology Department at Johns Hopkins University where he helped shape the minds of leading embryologists.
The goal of science education in the United States is promoting scientific literacy for all students. The goal necessitates understanding the nature of science-what science is as a body of knowledge, explanatory tool, and human enterprise. The history of science is one of the most long-standing pedagogical methods of getting at the nature of science. But scientific literacy also encompasses education in scientific inquiry, and in the relationships among science, technology, and society (STS), as well as fact and theory-based subject-matter content.
To address this issue, an innovation was developed and deployed for one semester at the Rio Salado College Avondale location. The innovation identified the individual career interests of each student in a treatment group, then worked with industry experts in those career fields to develop PowerPoint slides explaining how each HSE math lesson would directly transfer to the student’s career of interest. In addition, hiring managers from each career field that the students expressed interest in visited the class to discuss the need for HSE math skills and to answer any questions about their career and the transferability of what the students were learning.
The treatment groups’ attendance hours, completion rates, and self-reported engagement were examined and compared all other HSE math classes at Rio Salado College that took place during the same semester, as well as compared to the instructor of the innovation’s previous math classes. The results showed that students who participated in the innovation had, on average, over 38 more attendance hours than students who did not receive the innovation during the same semester and over 44 more attendance hours than the instructor’s previous classes at the same location. In addition, students who participated in the innovation reported higher engagement and enjoyment in the class than in similar HSE classes that they had previously taken.
This study explored the ways a safe space was coconstructed for the sharing of stories and voices and what was learned from families through their writing about who they are, what matters to them, and what they envision for their futures. To understand Somos Escritores, and the Latina adolescent girls, mothers, and fathers who participated in this space and the stories that are shared, I weave together multiple perspectives. These perspectives include Chicana feminist epistemology (Delgado Bernal, 1998), third space (Gutiérrez, 2008), Nepantla (Anzaldúa, 1997) and sociocultural theories of writing (Goncu & Gauvain, 2012; Prior, 2006). Data were drawn from the following sources: (a) postworkshop survey, (b) audio recording and transcription of workshops, (c) interviews, (d) workshop artifacts, and (e) field notes. They were analyzed using narrative methods. I found that Latina adolescent girls and their mothers and fathers are “Fighting to be Heard,” through the naming and claiming of their realities, creating positive self-definitions, writing and sharing silenced stories, the stories of socially conscious girls and of parents raising chicas fuertes [strong girls]. In addition, Somos Escritores families and facilitators coconstructed a third space through intentional practices and activities. This study has several implications for teachers and teacher educators. Specifically, I suggest creating safe space in literacy classroom for authentic sharing of stories, building a curriculum that is relevant to the lived realities of youth and that allows them to explore social injustices and inequities, and building relationships with families in the coconstruction of family involvement opportunities.
