Developing Meaningful Student-Teacher-Scientist Partnerships

This article describes the Earth System Scientist Network, in which students and teachers participate in research projects with scientists. In these projects the scientists can take advantage of having an extended research team, and the students and teachers can contribute to a research project while developing skills in inquiry and expanding content knowledge in Earth system science. Several issues must be addressed in order to facilitate these partnerships: identifying the scientific research questions, the data that the students will analyze, the requirements for participating schools, and the tools and protocols that the students and teachers will use during their research. Other logistical issues must also be addressed, such as assuring that instruments and tools are available to the teachers and students, providing the background information and training they will need, providing additional research questions that can help spark students' interest, and recognizing students and teachers for their contributions.

A family resemblance approach to the nature of science for science education

Although there is universal consensus both in the science education literature and in the science standards documents to the effect that students should learn not only the content of science but also its nature, there is little agreement about what that nature is. This led many science educators to adopt what is sometimes called “the consensus view” about the nature of science (NOS), whose goal is to teach students only those characteristics of science on which there is wide consensus. This is an attractive view, but it has some shortcomings and weaknesses. In this article we present and defend an alternative approach based on the notion of family resemblance. We argue that the family resemblance approach is superior to the consensus view in several ways, which we discuss in some detail

Teleology and Realism in Leibniz's Philosophy of Science

This paper argues for an interpretation of Leibniz’s claim that physics requires both mechanical and teleological principles as a view regarding the interpretation of physical theories. Granting that Leibniz’s fundamental ontology remains non-physical, or mentalistic, it argues that teleological principles nevertheless ground a realist commitment about mechanical descriptions of phenomena. The empirical results of the new sciences, according to Leibniz, have genuine truth conditions: there is a fact of the matter about the regularities observed in experience. Taking this stance, however, requires bringing non-empirical reasons to bear upon mechanical causal claims. This paper first evaluates extant interpretations of Leibniz’s thesis that there are two realms in physics as describing parallel, self-sufficient sets of laws. It then examines Leibniz’s use of teleological principles to interpret scientific results in the context of his interventions in debates in seventeenth-century kinematic theory, and in the teaching of Copernicanism. Leibniz’s use of the principle of continuity and the principle of simplicity, for instance, reveal an underlying commitment to the truth-aptness, or approximate truth-aptness, of the new natural sciences. The paper concludes with a brief remark on the relation between metaphysics, theology, and physics in Leibniz

Design, Fabrication, and Testing of an Electrospinning Apparatus for the Deposition of PMMA Polymer for Biomedical Applications

This paper describes the successful design and fabrication of a deposition system for synthesis and assembly of nanoscale and submicron sized fibers of poly(methylmethacrylate)(PMMA) polymer. To optimize the electrospinning deposition process, the distance between the needle and the electrically grounded substrate, the applied voltage, and the concentration of PMMA polymer in the solution were varied. PMMA fibers as small as 500 nanometers were observed using scanning electron microscopy (SEM). The chemical signature of PMMA was confirmed for best quality and retention of chemistry using Fourier Transformed Infrared spectroscopy (FT-IR). PMMA is a biocompatible polymer, and nanofibers of PMMA are key building blocks for scaffolds and other biomanufacturing applications, such as bioprinting for regenerative medicine and tissue engineering of synthetic organs (Mo, 2004)

From Cells to Cell Theory: What Would Kuhn Say?

Cells as we know them today were discovered in the 1600s by Robert Hooke. A couple hundred years later, scientists came to a final conclusion about how cells arose. The theory of spontaneous generation of life was abandoned in favor of cell theory, the idea that all cells come from preexisting cells. Louis Pasteur was an important thinker and experimentalist in this transition. Furthermore, the implications of this transition were far reaching and can even be seen today with the constant use of HeLa cells in scientific research. But what would Thomas Kuhn, philosopher of science, have to say about this transition? Does this transition fit into his conception of a paradigm shift? Does the transition alter the scientific imagination in such a way as to transform the world of scientists and alter the cultural perspective? If Kuhn was still around, he definitely would agree that this transition meets all his requirements for an effective paradigm change

Beyond subjective and objective in statistics

We argue that the words "objectivity" and "subjectivity" in statistics discourse are used in a mostly unhelpful way, and we propose to replace each of them with broader collections of attributes, with objectivity replaced by transparency, consensus, impartiality, and correspondence to observable reality, and subjectivity replaced by awareness of multiple perspectives and context dependence. The advantage of these reformulations is that the replacement terms do not oppose each other. Instead of debating over whether a given statistical method is subjective or objective (or normatively debating the relative merits of subjectivity and objectivity in statistical practice), we can recognize desirable attributes such as transparency and acknowledgment of multiple perspectives as complementary goals. We demonstrate the implications of our proposal with recent applied examples from pharmacology, election polling, and socioeconomic stratification.Comment: 35 page
