Quine argued that any context allowing substitution of logical equivalents and coextensive terms is truth functional. We argue that Quine's proof for this claim is flawed.

In an effort to address the problems confronting the American education system, the Obama administration has issued structural and systematic reforms such as _Race to the Top_. These initiatives introduce new statistics and accountability systems to gauge what constitutes "good" teaching, both from an administrative standpoint and the perspective of teacher training programs. This volume offers a direct critique of this approach, concluding that it does not respond adequately to the issues of education reform but rather raises new problems and (...) actively stymies progress. The author argues that at the heart of the confusion lies a misguided and rationalistic view of teaching and learning. He draws on the philosophical strategies of Ludwig Wittgenstein to break down the guiding assumptions of _Race to the Top_, allowing both the positive and the negative aspects of the policies to be heard. The author then proposes a different view of teaching and learning which considers how to effectively address the problems _Race to the Top_ seeks to confront. (shrink)

The differentiation of mammalian neurons during development is a highly complex process involving regulation and coordination of gene expression at multiple steps. The P19 mouse embryonal carcinoma cell line is a suitable model system with which to analyze regulation of neuronal differentiation. These multipotential cells can be maintained and propagated in tissue culture in an undifferentiated state. Exposure of aggregated P19 cells to retinoic acid results in the differentiation of cells with many fundamental phenotypes of mammalian neurons. Undifferentiated P19 cells (...) are amenable to genetic manipulations such as transfection and establishment of stable clonal cell lines expressing introduced genes. Proteins that play a key role in the neuronal differentiation of P19 cells are beginning to be identified. These include retinoic acid receptors, the epidermal growth factor receptor and the transcription factors Oct‐3 and Brn‐2. The biological and technical advantages of this system should facilitate deeper analysis of the activities of proteins that play a role in neuronal differentiation. (shrink)

The Wisdom We're Born With explores the desire to live that we carry with us from birth. While some people may believe that it's impossible to acquire perspective like Gottlieb's without a similarly catastrophic life experience, the fact is that every infant possesses a raw need to keep on going. Gottlieb's book awakens us to the idea of our natural perspective, traces the growth and diminishment of that perspective over the years, and brings us back to advanced age, where it (...) recurs once more. If we are aware of this capacity in ourselves, we can actively nurture it, enabling ourselves to embrace the desire to live and grow every day, whether we're joyful or in the grip of a powerful depression. In a time of anxiety and worry, Gottlieb's words provide comfort and strength-if we can remember the wisdom we're born with, we can possess a limitless energy to keep fighting. (shrink)

Both contemporary popular and scholarly discourse on teacher development and evaluation assumes the truth of a certain view of normative human behavior, one that holds that skill in a given domain is predicated upon the application of maxims, rules, or principles in a given situation. Such a view would allow one to isolate behaviors associated with expert practice, distill the rules that give rise to them, and both develop new teachers and evaluate practicing teachers on the basis of such maxims. (...) In this essay, Derek Gottlieb argues that the phenomenon of skillful teaching, and studies thereof, expose the inconsistencies and confusion underlying this model, encouraging the field generally to consider alternative holistic accounts of expert teacher practice as we seek to train and appraise great teachers.
